Weaponry Sight Device
The present invention relates to equipment for use in the
activity of shooting projectiles by a firearm or a bow, more
particularly to an apparatus for the laser guidance of the aiming
function used by the shooter, and fiber optics to increase the
usability of the weapon.
(Although this sighting device seems most particulari y
useful to a shooter at elevated heights, its concepts also provide
advantages when shooting at ground elevations.)
A basic principle utilized by the present invention is that
gravity consistently gives a downward "drop effect" to projectiles,
during the entire distance which projectiles traverse the ground;
whereas a laser beam is unaffected by gravity.
1.
CA 02273116 2007-03-14
1 Thus, the lowering of the laser with respect to the
shooting apparatus causes the sighting dot to be lowered, which
in turn causes the hunter to have to raise the angle of his shooting
apparatus in order to bring the sighting dot back to the desired
elevation at the target distance,which elevation-change causes a
raising of the projectile's flight-trajectory. Such type of
adjustment is provided by a vertically movable and vertically
adjustable cam member.
A second adjustment provided through arm linkage adjusts a
rotatable laser holding memeber, in an'assembly which is novel in
certain respects over the prior Reed patent.
That is, a pendulum-weighted body of the cam assembly causes
the cam to remain in the same orientation with respect to the earth
even though the shooting apparatus inclination is changed; and this
also provides a coordination between the inclination of the shooting
device with respect to the earth and the inclination of the laser
unit.
Two types of laser related adjustments are provided, one
being manual and the other being automatic.
A further novel feature embodied in the laser basis is the
provision of a novel adjustable base means to adjust the laser
2.
CA 02273116 2007-03-14
1 for horizontal (windage) adjustment of a shooter's projectile,
two adjusting stations being provided giving maximum precision
adjustment by convenient manual means.
A second advantageous feature of this sight system is the
concept of the use of fiber optics to give the shooter the means
by which he is able to aim and shoot at farther targets in
comparison to the lasers' limits of rangeability_; and thus this
fiber optic feature is greatly desirable to supplement the laser
feature of the sight device.
This fiber optic sight feature also provides a novel means
for the shooter to adjust the fiber optic components to provide a
range finding capability with the use of a novel sight pin feature.
A further novel concept is the provision of the combination
of the laser having an adjustable lens device by which the laser
beam can be adjustably expanded rather than constricted, this being
a novel combination not provided by any prior art laser guidance
systems.
These and other features are detailed herein, novel as
contributing their own novel features and as co-operating components
of the combinations achieved.

CA 02273116 2007-03-14
In hindsight consideration of the present invention to
determine its inventive and novel nature, it is not only
conceded but emphasized that the prior art had details usable
in this invention, but only if the prior art had had the guidance
of the present concepts of the present invention, details of
both capability and motivation.
That is, it is emphasized that the prior art had or knew
several particulars which individually and accumulatively show the
non-obviousness of this combination invention. E.g.,
a. The prior art has long had shooting devices of
various types;
b. Laser-details and the advantages of lasers as
sight-assisting features are well known in the weaponry art;
C. Lasers, as fascinating articles of technology, have
been known and used for many years, and have established themselves
as greatly and confidently useful, and adaptable to various
mechanisms in several arts;
d. Fiber optics, of various forms, have been used
and incorporated into many types of apparatus for many years, and
for several years have been used specifically as a guidance
alignment in various weaponry;
4.
CA 02273116 2007-05-28
e. Both lasers and fiber optics have been known
and used worldwide, several years, but to the Inventors, knowledge
have never been used in combination with each other and particularly
not to create the novel combination of the present invention;
f. The prior art has had the knowledge of the
typical desire of assisting the aiming for utmost precision in
hitting a target accurately;
g. The prior art knew the action of target animals
in moving between locations in a considerable span of distance;
h. The prior art has been aware of the problems
inherent as to differences in shooting length, nature of different
shooting device features in consideration of size, shape, weight
"pulling strength" and force;
i. The prior art of the industry has surely supposed
or known that many customers have been and surely would be quite
willing to purchase improved and more accurate and consistent
shooting apparatus, providing not only an easy and convenient
aiming apparatus, but one which attains high precision at various
distances and elevations;
J. The industry and users have surely known that even
novices would hope and expect to soon attain the skill of expert
marksmen, and be willing to pay for this hopeful achievement;
5
CA 02273116 2007-05-28
1 k. The relative ease of tooling and manufacturing
of components of this shooting apparatus have surely given
manufacturers ample incentive to have made modifications for
commercial competitiveness in a competitive industry if obvious;
1. The prior art has always had sufficient skill to
make many types of shooting aids, movable-parts products and
various articles having a variety of parts, more than ample
skill to have achieved the present'-invention, but only if the
concepts and their combinations had been conceived;
M. Substantially all of the operational characteristics
and advantages of details of the present invention, when
considered separately from one another and when considered
separately from the present invention's details and
technical accomplishment of the details, are within the skill
of persons of various arts, but only when considered away
from the integrated a.nd novel combination of concepts 4Thich
by their cooperative combination achieves this advantageous
invention;
n. The details of the present invention, when
considered solely from the standpoint of construction, are
relatively simple, and the matter of simplicity of construction
has long been recognized as indicative of inventive creavity;
and
CA 02273116 2007-03-14
o. Similarly, and a long-recognized indication of
inventiveness of a novel combination, is the realistic
principle that a person of ordinary skill in the art, as
illustrated with respect to the claimed combination as
differing in the stated respects from the prior art both as
to construction and concept, is that the person of'ordinary
skill in the art is presumed to be one who thinks along the
line of conventional wisdom in the art and is not one who
undertakes to innovate.
Accordingly, although the prior art has had capability
and motivation, amply sufficient to presumably give incentive
to the development of a weapon accessory according to the
present invention, the fact remains that the present invention
awaited the creativity and inventive discovery of the present
Inventors. In spite of ample motivation and capability shown
by the illustrations herein, the prior art did not suggest this
invention.
In spite of all such factors of the prior art, the
problem here solved awaited these Inventors' present
creativity. More particularly as to the novelty here of the
invention as considered as a whole, the resume of the prior
art uses and needs helps to show its contrast to the present
concepts, and emphasizes the advantages, novelty, and the
7.
CA 02273116 2007-03-14
inventive significance of the present concepts as are here
shown, particularly as to utility, accuracy and convenience of
use as detailed herein.
Moreover, prior art articles known to these Inventors
which could possibly be adapted for this duty fail to show
or suggest the details of the present concepts as
combinations;and a realistic conaideration of the prior art's
differences from the present concepts of the overall
combination may more aptly be described as teaching away from
the present invention's concepts, in contrast to suggesting
them, even as to a hindsight attempt to perceive suggestions
from a backward look into thV prior art, especially since the
prior art has long had much motivation as to details of the
present invention and to its provisions.
And the existence of such prior art knowledge and
related articles embodying such various features is not only
conceded, it is emphasized; for as to the novelty here of the
combination and of the invention as considered as a whole, a
contrast to the prior art helps also to remind both the qreat
variety of the various prior art articles and the needed
attempts of improvement,.and of the advantages and the
inventive significance of the present concepts. Thus, as
shown herein as a contrast to all the prior art, the
8.
CA 02273116 2007-03-14
inventive significance of the present concepts as
combinations is emphasized and the nature of the concepts and
their results can perhaps be easier understood as inventive.
Although varieties of prior art are conceded and ample
motivation is shown and full capability in the prior art is
conceded, no prior art shows or suggests details of the
overall combinations of the present invention as is the proper
and accepted way of considering the inventiveness nature of
the concepts.
That is, although the prior art may show an approach to
the overall invention, it is determinatively significant that
none of the prior art shows the novel and advantageous
conc,ept,s in combination, which provides the merits of this
invention, even though certain details are shown separately
from this accomplishment as a combination.
And the prior art's lack of an invention of a shooting
apparatus, achieving the convenience, accuracy, simplicity of
use and other advantages of the present invention, which are
goals only approached by the prior art, must be recognized as
showing a long-known need, now solved.
Accordingly, the various concepts and components are
conceded and emphasized to have been widely known in the
prior art as to various devices; nevertheless, the prior art
9.
CA 02273116 2007-03-14
1 not having had the particular combination of concepts and
details as here presented and shown in novel combination
different from the prior art and its suggestions, even
only a fair amount of realistic humility to avoid
consideration of this invention improperly by hindsight
requires the concepts and achievements here to be
realistically viewed as novel combinations, inventive in
nature. And especially is this a realistic consideration
when viewed from the position of a person of ordinary
skill in this art at the time of this invention, and
without trying to reconstruct this invention from the
prior art without use of hindsight toward particulars not
suggested by the prior art.

(Noting especially Figs. 2 and 2A, in the "exploded
view" presentations, the limits of the Drawing paper have
required a certain "staggering" of axes of presentation,
and thus what might appear to be the displacement of
certain components; but with that reminder there should
be no confusion in interpreting the Drawings in that
regard.)
15.
CA 02273116 2007-03-14
As of course is well known, the cocking of the apparatus
by the user pulling on the bow string,and forward support of
the arrow by the user's forward hand,gives an aiming effect
to th-e-arrow, the aiming being achieved as the user's forward
hand is moved vertically and thus with respect to the rear end
of the arrow whose elevation is substantially constant, being a
functton of the user's height and relative length of his rear
arm-sections.
Accordingly, as is of course also well known, the user
must elevate his forward hand to achieve a relatively longer
arrow trajectory, due to the fact that the user must impart an
upward component to the trajectory of the arrow's flight path to
compensate for the effect of gravity.
The factors of distance to the target and resilience
characteristics of the bow of course are factors which must be
accounted for in order for the arrow tip to strike the target
by being at the proper vertical height when the arrow has
travereed the trajectory to the target.
16.
CA 02273116 2007-03-14
In the use of the laser sighting unit, the user will
look specifically upon the target for the presentation or showing
thereon of the laser's "sighting dot", in contrast to the
sighting-use of a conventional bow and arrow assembly in which
the user would "sight along" the arrow to physically observe the
initial inclination of the arrow's trajectory.
Also, in considering the sighting and target-accuracy
of this laser-guided sight system, it is assumed that the hunter's
skill of aiming will laterally center the arrow and its trajectory
sufficiently centrally of its lateral or horizontal trajectory,
that the aiming details here discussed relate wholly to the vertical
aiminq aspect.
The concepts herein are generally shown with respect to
archery and its factors of construction and operativity; although
the concepts are not limited to archery, and the correlation of
archery factors to other weaponry factors should'presumably be
quite apparent.
As shown in the Drawings,thE!Qoncepts for the guidance
means 13 of this invention are shown in association with a bow 14,
the bow 14 having a riser 15, a bow window 16, and a handle 17.
Fig. 1 also shows in association with the bow 14 a momentary switch
18 which provides circuitry (Fig. 6, e.g.) to the laser component
(64) shown in Figs. 2,2A,6,7,7A,8 and 9. Bolts (not shown) connect
17.
CA 02273116 2007-03-14
1 the guidance means 13 to the bow 14 by passing through
aligned holes 19 in the bow 14 and in the guidance means
13's sight bracket (82).
Turning now to the concepts for the guidance
apparatus 13 used with the bow 14, they are shown as
contained within a framing containment housing 20, which
is shown as a rec-tangular box, part of which is shown as
"broken away" in Fig. 1 for better illustration of
interior details. The housing 20 is a sturdy framing 20.
The containment housing 20 is provided with
circular adjustment slots 22 (See Fig. 2 and_other
Figures) which are provided for fiber optic light
receivers 30 of light receiver assemblies 30A described
in connection with their operativity.
A switch 24 is carried by the containment housing
20, which has circuitry 25 (Fig. 6) which leads to the
laser diode (64) as described below, circuitry containing
battery 25A shown in Figs. 6,9 and 11.
The bottom wall 20A of the containment housing 20
is provided with a hole 26 which accommodates adjustment
as described below for adjusting cam (39) component
shown in Fig. 2 and other Figures.
18.
CA 02273116 2007-03-14
Jam nuts 28 are threaded onto respective light receivers
30 xhich receive light through fiber optic holders (adjustment
tubes) 31 with operativity described below. Three sets of light
receiver assemblies 30A are shown, for illustration in Fig. 9
mounted on the containment box 20. Each light receiver assembly
30A is illustrated in Fig. 11 showing the first large component
located or installed in adjustment slot 22, referred to as the
"light receiver" because of its position as being the first
component of the light receiver assembly 30A to receive light
through its interiorally threaded core containing the fiber optic
adjustment tube 31.
Other jam nuts 32 are threaded onto the adjustment tubes
31 to jam against the light receivers 30 to hold the adjustment
tube 31's adjusted poeitiona
Crimp nuts 33 are threaded on the ends of adjustment tube
31 to crimp adjusted tube 31's end against the fiber optic cable's
cladding 76 to hold the adjusted position of the fiber optic
cables 34.
The window 35 of the containment box 20 is the opening
in the forward wall 35A of the containment box 20 for laser beam
projection (66) and laser adjustment described below.
Side cover plate 36 is held by screws 38 onto the box 20
on the side of the box 20 opposite to the side wall 36A which
contains the circular adjustment slots 22. (Figs. 2,6,7 and 8)
19.
CA 02273116 2007-03-14
The side cover plate 36, and its opposed counterpart
wall 36A of containment box 20, have a multi-purpose component 40
(shown most clearly in Fig. 11) and providing ciperativity
described below.
Each multi-purpose component 40 comprises exterior male
threads 40A which thread into female threads 40B of the box 20's
walls 36 and 36A, respectively, providing transverse adjustment
described below, of axles 43C and 43D of the pendulum assembly
(48), Fig. 11, described below.
That is, transverse movability of the axles 43C and
43D is provided by each of the axles 43C and 43D bearing outwardly
against a-C-shaped piston member 40C, there being a compression
spring 40D bearing inwardly against that piston member 40C and
bearing outwardly against the outward wall 40E of each multi-
purpose component 40, the springs 40D transmitting the adjustment
force by pressing imwardly against the respective piston 40C.
The springs 40D also act as shock absorbers to reduce shock
from the bow's recoil due to the high force involved in the arrow
projection factors , the spring 40D being interposed between the
axles of the pendulum assembly 48 and the multi-purpose component
40 which is connected to the housing 20's wall.
20.
CA 02273116 2007-03-14
Still noting especially Figs. 1,7 and 11, the multi-purpose
components 40 provide adjustment of the pendulum assenibly 48
transverse with respect to the box 20, by twisting either of the
multi-components 40; for both of the axles 43C and 43D are connected
to the top portion 48A of the''pendulum assembly 48 and thus in that
sense are connected to one another, the goal of such adjustability
being the transverse adjustment movement of the pendulum assembly
48 (Figs. 1,7 and 11) being to achieve desirably tight (although
relatively movable) mating connection of the cam track 39A and arm
50'a fingers 52 as may be desired particularly as in assembly or
maintenance proceduree.
Another function of each multi-purpose component 40 is
that its inner wall 40F has a central opening which provides a
bearing for the axle 43C or 43D as the pendulum aeeembly 48 pivots
during the maneuvering of the bow and sight combination in the
aiming procedure detailed herein.
Such pivoting of the pendulum assembly 48 is provided by
there being a freely turning rotational support of axles 43C and
43D (by the central opening in inner wall 40F) and by the fact
that most or substantially all of the weight of the pendulum
assembly 48 is such that its center of gravity is below the axis
of axles 43C and 43D, as will be apparent by noticing (Figs. 4
and 11) that the cam 39 with its cam brack 39A is of light weight
21.
CA 02273116 2007-03-14
(preferably made of plastic) and the lower portion 48G of
the pendulum assembly 48 is made of a relatively heavy material
(such as metal).
This pivoting is automatic in response to aiming procedures
as to the bow 14 through its maneuvering (raising or lowering)
procedure, for the pendulum axles 43C and 43D are supported by
the multi-purpose components 40 which are connected (even though
screw-threadedly) to the housing wall 36/36A.
Cover plate 36 (and its counterpart 36A) also is provided
(Figs. 2,2A and 6) with a pin support hole 41 which serves to
support a pin 42 of the laser holder 42A. Pin 42 acts as an axle
during actuation described below, the pin 42 being supportively
journaled in support hole 41 in cover plates 36 and 36A.
The laser holder 42A, and its most-related parts are shown
best in Fig. 2A, the laser holder 42A shown as being an important
part of the linkage which ultimately changes the orientation of
the laser diode 64.
22.
CA 02273116 2007-03-14
The hole 41 has its counterpart support opening in the
opposite wall of the container box 20, i.e., the side wall 36A
containing the slots 22. (See Fig. 6)
In the pendulum assembly 48 there are multiple LED sockets
43 (see Figs. 3,4, e.g.). In these sockets 43, LEDs 43A are shown
by dash lines in Fig. 7 and in Fig. 11 by a single LED 43A in dash
]ines. The LEDs 43A are provided circuitry 43B (Fig. 11) a portion of
that circuitry 43B being contained in vertical channels 48B
(Fig. 3), the circuitry 43B leading to the axle 43C and axle 43D,
which serve as components of the circuitry 25 through the
battery (25A).
The axles 43C and 43D are installed in the top portion 48A
(shown in F-igs. 2,2A,3,4 and 11) of the pendulum assembly 48 which
consists of a non-conductive material to avoid shorting out
electrical circuitry 43B. The LED sockets 43 are provided in the
lower portion 48G of pendulum assembly 48.
The axles 43C and 43D which are pressed into the top
portion 48A of the pendulum assembly 48 are pressed securely
against electrical contacts 25B and 25C thus completing the battery
circuitry 25 (see.Fig. 11). When the pendulum assembly 48 is
installed in the containment box 20 the axles 43C and 43D provide
circuitry to the multi-purpose components 40 which completes the

1 Another significant concept is the provision
of a cam 39 (Figs. 1,2,3,3A,4,7,8 and il) whose cam
base 44 (Figs. 3A and 4) has a threaded hole 44A to
receive an adjustment screw 46, rotatable to adjust
the cam 39 for programming the cam 39with respect to
bow pull force and arrow characteristics, explained
further below.
A spring 47 ensleeved about the shaft of screw
46 supplies upward force against the cam 39 by being
bottomed against the cam base 44 and a spring nest 49
of the pendulum assembly 48. The effect of this is to
hold the screw 46 upward because the screw 46 is
threadedly connected to the cam base 44, desirable for
cam adjustment explained below.
Turning of the screw 46 clockwise or counter-
clockwise serves, by its threaded engagement with the
non-rotatable cam base 44, to move the cam base 44 and
cam 39upward or downward, causing the cam track 39A to
provide an adjustment of the laser holder assembly 68
by controlling the motion of the arm 50 and its fingers
52, the laser holder assembly 68 being more fully
described below.
The cam 44 is a lug of square cross-section so as
to be held against rotation by its non-circular nature
blocked against rotation by a square wall 45 of the
pendulam assembly 48 (See Figs. 1-3).
24.
CA 02273116 2007-03-14
A feature of the cam 39 is a cam track 39A in the
form of. a partial ring protruding from the cam 39, the
cam brack 39A supporting a laser holder adjustment arm 50,
by the fingers 52 of that arm 50 slidably receiving the
cam track 39A (See Figs. 1,7 and 8), the arm 50 and fingers
52 serving as a cam bollower of cam 39 for adjustment effects
detailed below.
The laser holder arm 50 has its forward end 54 bent
900 , (Figs. 1,2 and 2A) to provide a transverse wall or ear
surface 54 which supports an adjustment screw 56 effect
explained below.
Noting especially Figs. 2,2A and 7, as to details of
that laser holder arm 50 and its oeprativity, Fig. 7, those
Figures show the laser holder assembly 68 comprising
adjustment screw 56, which extends through a clearance hole
54A in the 90 bent ear or tab 54, spring 58, clearance hole
59 in the bottom portion of the laser holder 42A, a threaded
hole 59A in horizontal adjustment pin 60 when it is inserted
into horizontal hole 63 (a free fit therein), lock nut 62,
axle pivot pin 42, laser holder 42A, laser holder adjustment
arm 50, laser receiver hole 59G, and laser diode 64 inhole
59G which projects a laser beam 66 outwardly of box 20
through its forward wall window 35 of front wall 35A.
25.
CA 02273116 2007-03-14
The spring 58 bottoms against the back side of tab 54
and bottoms againat the front side of laser holder 42A. Tab 54
is stationary, however, because the hole 41A in holder arm 50
receives and is thus located by the horizontal pivot pin 42 which
is received and located by hole 41 in containment housing wall
36 and 36A; and thus any compressive bias in the spring 58 pushes
against the front side of the laser holder 42A to cause the holder
42A to pivot about its axle pin 42, the amount of such pivoting being
controlled as a function of the adjustment of the screw 56 in
pin 60's female threaded hole 59A as blocking continuation of
pivoting of the laser holder 42A. Such bias in spring 58 is thus
controlled by the rotational adjustment of screw 56 which is
freely fit in holee 54A and 59.
With the laser holder assembly 68 mounted in the containment
housiriq 20, the assembly 68 can be adjusted to allow the laser
holder 42A to adjust forward or backward by rotating the adjust-
ment screw 56.
There are two angular adjustments of laser 64 and its laser
beam 66 which are provided by rotating the control screw 56 of the
laser holder assembly 42A, one being a forward adj-ustment and the
second being a rearward adjustment, which indirectly adjust the
laser beam 66, by adjusting the orientation of the laser support
holder 42A as to its rotational setting about the axis of transverse
26.
CA 02273116 2007-03-14
support pin 42, which correspondingly adjuata the angular setting
of laser receiver hole 59G and thus the laser device 64, because
of the laser device 64's tight fit in the receivar hole 59G.
With the threads of adjustment screw 56 extending through
pin 60's hole 59A inadvertently to the back side of laser holder
42A, lock nut 62 is installed on the end of the adjustment screw
56 to act as a safety stop to keep the screw 56 from being baoked
out of the adjuster pin 60.
Aa to the fiber optic components concepts and details,
in addition to the laser guidance features, the features provide for
the archer the advantage of a second feature sighting device, moet
particularly useful when the laser's "sight-dot" cannot be seen
on occasions when the sun's brightness overcomes the laser beam.
Although fiber optic features have been used in constructions
in which fiber optic features are attempted to be used in providing
the archer with an improved sighting means over the prior art of A
standard sight pin, the fiber optic. constructions. of the prior art
as known to the Inventors are of scintillative type in which ambient
light in nature i~ collected by the scintillative cable and
intensified by collection of light through and along its length
and transferred to the ends of the fiber optic cables, vith a direct
result of the ends of the cable showing a high brillance of
illumination.
With that prior art type of fiber optics use, the archer
uses that brillantly lit end of the fiber optic cables as a
sighting guide (sighting pin dot) compared to a standard sight pin,
27.
CA 02273116 2007-03-14
and the fiber optics improvement provide the archer with a
sighting means by which sight dots or sight pins are visibly seen
longer in the evening as sunlight is reduced. Such prior art use
is built upon by the present invention's concepts, which diverqP
from the prior art in the important feature of this invention"$
use of novel particulars of the construction and use of a
sealed light chamber 70 and other details.
Standard sight pins have considerably less illumination
in lox-light conditione compared to the scintillative fiber optic
nature of collecting light in low light conditions; and this
contrast shoWs the advantage expected and obtained by the use of
a special type of scintillative optic cables according to the
present concepts.
Accordingly, as shown In the Drawings and as herein d_escr-ibed
the special type of fiber optics of the present invention are set
forth in contrast to such prior art as well as bo detailed features
and components themselves.
More particularly, as to the features of the-present
invention, fiber optic cables 34 (Figs. 9 and 11) receive liqht from
the LEDs 43A, through the ends of the fiber optics which are installed
in the light receivers 30, the fiber optic cables 34 continuinq as
shown and exiting the light receivers 30 and leading to the sealed
light chamber 70 of housing 20 after entering the box 20.
The light chamber 70 contains an independent light source
72 (Figs. 6,7,8 and 9) for an optional use described below.
28.
CA 02273116 2007-03-14
1 The fiber optic cables 34 are shown schematically
as entering the sealed light chamber 70 in Figs. 7 and 9;
but their pathway is shown more completely in Fig. 9 as
including a partial interim portion 74 in whichthe cladding
76 has been stripped. Exteriorly of the sealed light
chamber 70 the cables 34 are clab 76, i.e., coated with
light fibrous insulation 76, providing that no ambient
light may enter along the exterior length of the fiber
optic cables 34 which would embellish the light coming from
the light receiver assemblies 30A.
The fiber optic cables 34, after exiting the sealed
light chamber 70 through wall 36A, continue to the light
output assemblies 80 which are received by the lower part
of sight bracket 82 in vertical adjustment slots 84, the
slots 84 accommodating vertical changes of the position of
light output assemblies 80 with their respective sight pins
78 which achieves alignment of sight pins 78 to respective
targets and their use respectively.
The light output assemblies 80 are shown in Figs.
1,2,9 and 12. The fiber optic cables 34 are axially
received respectively by a light output adjustment tube
86. The cladded fiber optic cables 34 extend to the center
center portion or area 88 of the light output adjustment
tube 86. This center area 88 is a light transfer and
adjustment tube 86. This center area 88 is a light
transfer and adjustment chamber 88 to adjust light transfer
29.
CA 02273116 2007-03-14
1 (bright to dim or dim to bright) by simply loosening
crimp nut 96 on the flexible fiber optic end of
adjustment tube 86; then the shooter can dim or
brighten the sight pins 78 by either pulling the cable
34 farther out or pushing the fiber optic cables 34 in,
respectively. The crimp nut 96 can be re-tightened to
maintain that adjustment.
Still noting Fig. 12 especially, the light output
adjustment tube 86 also holds and maintains adjustment of sight
pins 78. The sight pins 78 are held securely in the adjustable
tube 86, and also is rotational about its own axis (which is the
sameas the axis of the light output adjustable tube 86), by
loosening the crimp nut 100 and then re-tightening the crimp nut
(100) after the desired adjustment is made. The outer portion of
sight pins 78 are desirably made of a rigid cladding 102 to maintain
a bent shape as well as to provide a light shield cladding effect.
The interior portion 104 of sight pins 78 is formed of fiber optic
material 104, coated with a rigid cladding 102.
Still noting Fig. 12, the light output adjustable tube
86 is threadedly installed in adjustable tube holder 90 which is
received in one of long vertical adjustment slots 84 in sight
brar.ket 82 (See Figs. 1,2,6 and other Figures), the slot nature of
the openings 84 accommodating vertical adjustment for vertical
placement as.well as a means to give space to add several sight pins
78 to achieve further range-distance capabilities.
30.
CA 02273116 2007-03-14
1 Each adjustable tube holder 90 is a tube whose core
is threaded to accommodate the adjustable tube 86, and holder
90 is secured in its position in the slots 84 by a jam nut
92 which presses against a fiber lock washer 93.
Supplementing the laser and fiber optic concepts of
this overall invention, a novel and advantageous adjustment
base 106 provides laser alignment adjustment of the laser
64 and its laser beam 66, in addition to its provision of a
battery compartment 108 serving the electrical needs of the
system 13.
Alignment concepts as now detailed refer to windage
adjustment. Windage adjustment is a factor of horizontal
concern in contrast to vertical adjustment as to gravational
effects.
Windage adjustment provides the shooter a means to
adjust the sight left or right to control a projectile's
left or right shot placement to obtain an accurage hit on
the target.
The windage-considered alignment of the laser diode
64 and its laser beam 66 is very desirable, as it is
important to be able to properly align an archer's arrow
or a projectile's flight path, horizontally as well as
vertically.
31-
CA 02273116 2007-03-14
1 As now shown, this vital horizontal adjustment is
advantageously made by the following mechanism which
achieves a controlled horizontal adjustability of the laser
device 64 and the adjustable base 106, the adjustment of
those two factors achieving the precise horizontal
adjustment of the flight path of the arrow or other
projectile.
Such controlled horizontal adjustability i~; proviv:ed
at each of two stations 107 which are spaced along the
adjustable base 106.
Noting Figs. 2 and 10, especially, there is shown
the adjustment base 106 connected to the upper portion of
sight bracket 82, as particularly shown in Fig. 10, as to
each one of two portions or stations 107 of base 106. A
control screw 110 having a head 112 is installed
(leftwardly in Fig. 10) freely through a large-bore
threaded hole 113 at the right side (right in Fig. 10)
of the base 106. (The particulars as to the hole 113 are
given below.) Each of the two control screws 110 and its
corresponding hole 113,~and for one of two adjustment
stations 107, indicated as to both in Fig. 2 although only
one is shown in Fig. 10. Although there are two sets or
stations 107 of adjustments, each with its control screw
110, etc., in a less expensive embodiment it may be
32.
CA 02273116 2007-03-14
desirable to replace one set with some sort of a pivotal
connection; and even more economically it may be desired to
replace both of those sets of adjustment details by an
optionally usable plurality of spacers to attain the desired
relative spacing of the box 20 and the adjustment base 106 with
respect to the sight bracket 82 to thus achieve windage'control.
32a
CA 02273116 2007-03-14
After passing (leftwardly) through the base 106's hole 113,
the control screw 110 freely slides through a clearance hole 114
of a rotatable cylindrical screw retainer 116, the screw retainer
116 being installed into a round retainer socket 118 k1 the adjustment
base 106, at each of its adjustment stations 107.
The retainer 116 retains the horizontal position and the
rotational position of the control screw 110, accommodating the
relative rotation of the screw 110 while giving support to the
adjustment assembly features.
The end 119 of the screw 110 opposite its head 112,
in moving to its position shown in Fig. 10, passes (leftwardly)
through a large clearance hole 120 at the side face (left) of the
adjustment base 106.
The screw 110 is aligned with a threaded hole 122 of the
sight bracket 82; and the control screw 110 is finger started into
the threaded hole 122. Control of screw 110ie provided preferably
by an Allen head wrench socket in the head of screw 110. In use, the
control screw 110 is rotated (clockwise) until screw head 112 of
screw 110 rests (at 123) against the right face of the screw retainer
116, and the base 106 is forced tightly against sight bracket 82 by
the engagement of the threads on screw 110 and the female threads of
sight bracket hole 122.
It will be noted that a sufficient length of threads at the
leftward end 119 threadedly extend through the sight bracket 82 and
its holes 122 to receive adjustment control knobs 124 onto the
free ends 119 of each of the control screvs 110.
33.
CA 02273116 2007-03-14
1 After installation of each control knob 124, a set
screw 126 is threaded into a small-bore threaded hole 128,
and set screw 126 is forced against the screw 110's threads
to maintain the control knob 124's position.
At the opposite (right) end (as shown in Fig. 10) of
each adjustment set of 107 of base 106, a large set screw
130 is rotationally threaded into the large-bore.threaded
hole 113 until the set screw 130 loosely touches the
socket head 112 of the control screw 110 (although that
touching is not shown in the position of set screw 130
in Fig. 10).
In this position, the screw head 112 of control screw
110 is between the rotatable retainer 116 and the set
screw 130.
The control knob 124 is turned (clockwise) rotating
the screw 110 (clockwise) which forces the head 112 of
control screw 110 to push (rightwardly) against the set screw
130, with a direct result of the base 106 being forced to
move rightwardly from the bracket 82.
With base 106 adjusted rightwardly from the sight
bracket 82, by rotation of one or both bontrol screws 110,
a space 125 will exist between the end face 121 and the sight
34. -
CA 02273116 2007-03-14
bracket 82. If further adjustment is desired one or both
control screws 110 are now to be rotated to create whatever
spacing 125 is desired to achieve alignment as required,
more fully explained below. Any spacing adjustment at
either station 107 of a control screw 110, etc., will vary
the relative spacing between the sight bracket 82 and the
adjustment base 106.
The adjustment base 106 can be adjusted rightwardly or
leftwardly as desired to align the sight laser 64 (and the laser
beam 66) vertically parallel with an archer's arrow or firearm
projectile tube and its projectile.
The fine adjustability which is achieved by being able to
adjust one or both adjustment stations 107 ie particularly important,
and must be individually considered, for each bow and projectile
characteristics are likely to be significantly different.
Miscellaneous hardware is shown in various Figures
of the Drawings.
For example, the containment housing 20 as shown is
hinged by a lug 140 that is located on the lower front 35A
of the containment housing 20, the lug 140 being provided
with a horizontal hinge pin hole 142 which aligns with two
other horizontal hinge pin holes 144 on the front 141 of
the base 106. A slot 146 on the front 141 of the base 106
receives the lug 140. The hinge pin holes 142 and 144 are
aligned, and an axle pin 148 is installed through the hinge
35.
CA 02273116 2007-03-14
pin holes 142 and 144 coupling the containment housing
20 to the base 106.' (Fig. 5, especially)
On the rear 149 of the base 106 another slot 150
is provided to receive a latching device 152 that provides
a horizontal hinge pin hole 154.
The latching device 152 mates with the slot 150 and the
pin hole 154 is aligned with horizontal pin holes 156 on the rear
149 portion of the base 106. A hinge axle pin 158 is installed
into the hinge pin holes 154 and 156 which couples the latching
device 152 to the base 106. On the rear 149 portion of the
containment housing 20 a slot 160 is provided to latchingly
receive the latching device 152 into the slot 160 which securely
provides and maintains a closure of the base 106 to the housing 20.
Such easy openability is particularly advantageous for
battery replacement and adjustable alignment procedures.
Turning now to other embodiments which incorporate the
inventive concepts, attention is called to Figs. 13,14 and 15 as
general views embodying the concept, and particularly with reference
to similarities of use of the present concepts, on various types of
weapons and projectile throwers.
As shown in Fig. 13, the sighting apparatus 13 is mounted
onto a bow 14 as described in detail herein.
In contrast to Fig. 13, Fig. 14 shows the novel concept of
the sighting apparatus 13 embodied in a cross bow forearm stock
sight mount handle 162, and more particularly on the underside, the
underside being under the weapon's rail 164 (the rail 164 providing a
36.
CA 02273116 2007-03-14
1 resting support 166 or firing ramp support 166) for
a bolt to be fired referred to as a "cross bow arrow".
The bow.portion of a cross bow is mounted crosswise to
the rail frame.
That underside nature of the mounting of the sight
13 in Fig. 13 embodiment, the forearm stock sight mount
handle 162 is provided with a recessed underside pocket area
168 to accommodate the sighting apparatus 13.
Likewise, as to the Fig. 15 embodiment, the sight
13 in the Fig. 15 embodiment is also mounted in a forearm
stock sight mount handle underside pocket 168 which is on
the underside of the weapon's projectile tube 170.
This Section supplements the other descriptions, to
the extent that operativity can be shown favorably as a
supplement:
(1) Momentary swi,tch 18:
The momentary switch 18 is shown in Fig. 1 and is
embodied in circuitry 25 and 176 shown in other Figures, for
example, in Fig. 6. The momentary switch 18 is biased to
open-circuit condition, and leads to the external power
jack 172 shown in Figs. 6,7 and 8 with two terminals 174,
one terminal 174 leading to the battery 25A by circuit 25,
and the other terminal 174 leads to the laser circuitry 176
37.
CA 02273116 2007-03-14
1 described below. The effect and operativity of the
momentary switch 18 is to make the laser circuit 176
temporarily energized when the shooter desires to achieve
the temporary illumination of the laser beam 66; this
is by closing the circuit across the terminals 174 of the
jack switch 172.
(2) External dual-purpose power jack 172:
Powered by the battery circuit 25, the power jack 172
leads to the laser circuit 176 which circuit energizes the
laser diode 64, and the circuitry 176 is shown as leading to
the left one of the switch terminals of switch 24. Switch
24 is shown (Fig. 6) as a single-pole double-throw switch
in which the left terminal indicates the input terminal for
the laser circuitry 176 and includes the momentary switch
18 shown in Fig. 6 as one of the features of the circuits
25 and 176. The right terminal indicates the input terminal
for the LED circuitry 43B shown more clearly in Fig. 11.
The effect of energization of laser circuit 176 is
to cause the laser diode 64 to emit the laser beam 66, for
as long as the momentary switch 18 is in circuit-closing
position.
38.
CA 02273116 2007-03-14
1 The external power jack 172 accommodates the use of
an external power source (not shown) for a reduced-cost
embodiment which omits the built-in battery compartment
108 and its battery source 25A and the momentary switch
18; and thus it is referred to herein as a dual jack
172.
(3) The pendulum assembly 48:
The pendulum assembly 48 of Figs. 1,3,4,7 and 8
comprises LEDs 43A and the LED'circuitry 43B which is
installed onto the lower portion 48G of the pendulum
assembly 48.
Noting Fig. 11, the axles 43C and 43D serve two
purposes, i.e., one purpose being that each axle 43C and
43D is in series with LED circuitry 43B and battery circuitry
25 thereby energizing the LEDs 43A when the switch 24 is
turned "on" at the right terminal of the switch 24 in
Fig. G.
39.
CA 02273116 2007-03-14
1 The other purpose of those axles 43C and 43D is
to provide rotational support of the pendulum assembly
48, rotational with respect to the housing 20, for
operative purposes of holding the cam 39 always in a
constant orientation with respect to the earth and to
the housing 20 by the pendulum effect noted above of the
difference in the weight and shape factors of the two
portions 48A and 48G of the pendulum assembly 48.
The corresponding relative rotation of the housing
20 and bow 14 with respect to the pendulum assembly 48
and its cam 39 provides the functions now explained as to
each of the laser and the fiber optic functions.
(4) Relative rotation of pendulum assembly 48
serves laser function:
The relative rotation of the housing 20 and bow 14
with respect to the cam 39, the cam 39 being affixed to
the pendulum 48, causes the arm 50 of the laser holder
assembly 68 to follow, by arm fingers 52, the cam track
39A; and it is that slight rotational movement of holder
arm 50 about the axis of axle pivot pin 42 which (by the
linkage particularly shown in Fig. 2A) is operative to set
or change the orientation of laser diode 64 with respect
to the housing 20.
40.
CA 02273116 2007-03-14
As a shooter is aiming and maneuvering a shooting
device embodying the present concepts, his judgment of
distance is not raquired to be good; the orientation of
the housing 20 aids thp sight system 13 to achieve its
range adjustable feature.
That is, as the box 20 rotates about the pendulum
assembly 48, with corresponding relative rotation of
pendulum assembly 48 about the box 20, a direct result
is the cam track 39A sliding through the fingers 52 of the
holder arm 50; and the result is that the laser 64 and its
holding assembly 68 (Figs. 2A,7 and..8) automatically
rotating about the axis of axle pin 42, emitting its laser
beam 66 at the desired target regardless of its distance
(although of course within the capabilities of the weapon
and its projectile combinations).
As this rotation of the housing 20 and_bow 14 occurs,
relative to the laser 64, the laser 64 is range adjusting
with each increment of rotation of the laser holder 42A
to automatically change the relative orientation of the
laser 64 adjusting to a correct angle, emitting its beam
66 to a desired target.
This automatic vertical adjustment which is achieved
by the relative rotation of the pendulum 48 (and cam 39,
fingers 52, arm 50), is a second type of laser vertical
adjustment, the first being the manual adjustment achieved
41,.
CA 02273116 2007-03-14
by manual -rotation of control screw 56.
These adjustment features enable the shooter to need
only to release his projectile when the laser beam 66 is
visible on the target, considering here only the vertical
adjustments required by gravity. Horizontal adjustment is
explained as discussed below.
15) Relative rotation of pendulum assembly 48
serves fiber optic funct ons:
In addition to serving the function of the laser beam
66 direction,the relative rotation of the housing 20 and bow 14,
with respect to the pendulum assembly 48 (and cam 39) serves
(see Fige. 6,7,8 and 11) as a light transfer function explained
below.
That is, assume (Figs. 6 and 11) that the LEDs 43A have
been energized by switch 24 through circuitry 25 and 43B, emitting
light by that energization.
The light receivers 30 installed into the circular slots 22
of housing 20 are positioned in one or more circular paths 22 about
the axis of the axles 43C and 43D of the multi-purpose component 40
in the vails 36 and 36A.
Two of the light receiver paths (slots) 22 are ehown here
for illustration.
They are both arcs of circles concentric to the axis of
axles 43C and 43D, and the light receiver arcs 22 have the same
radii ae the distance of the respective LEDs 43A from the center
of the axles (shown in Figs. 7,8 and 11) from the center of the
arc slots 22 and the axis of the axles 43C and 43D.
42.
CA 02273116 2007-03-14
As the box 20 rotates, carrying the light receivers 30
for rotating toward or past the LEDs 43A, the LEDs 43A transfer
light to each light receiver 30 one at a time at different
angles of the box 20's rotation about the axis of axles 43C
and 43D; and the fiber optic sight function acts as an
automatic function to provide range finding capabilities.
Light receiver assemblies 30A can be taken out or more
can be installed and moved about as desired by the access
holes 178 in line with the slots 22 and slightly larger to
accommodate the installation and/or removal of light receiver
assemblies 30A.
Automatic range finding capabilities and automatic
functions are explained below. -
As the box 20 rotates, and a shooter is raising or
lowering his shooting device, the light receivers 30, which are
installed in the slots 22 of a wall 36A of the rotating housing
20, will rotate toward of past LEDs 43A installed in sockets
43 in the lower portion 48G of the pendulum assembly 48. The
LEDs 43A will emit light to the light receivers 30, and the
fiber optic cables 34 in the adjustment tube 31 accumulate the
received light and transfer it to the sight pins 78. The sight
pins 78 will light up one at a time (in the sight's automatic
function) and the shooter will use the brillantly lit shining
light pins 78 sequentially as his sighting guide 78 to align
between the shooter's eye and his desired target.

1 The shooter needs only to aim his shooting device and
align the only sight pin 78 shining and this sight pin 78
being aligned with the desired target, the shooter fires his
shooting device's projectile to achieve an accurate shot
placement.
The fiber optic feature addition to this sight system
is important, that is, this feature expands the capabilities
of the sight system to use several sight pins 78 to achieve
farther distance capabilities of the sight system 13, as
well as achieving a sight feature when the laser beam cannot
be seen upon a desired target.
These examples are few of many reasons why this fiber
optic addition advantageously supplements the laser features
of the sight system 13. The laser 64 feature is limited to
range-distance limits because of weaponry and projectile
characteristics and combinations correspondingly. It must
be understood that different weapons of greater force would
increase the limits of range distance of the sight system 13,
and weapons of lower force would decrease limits of range distance.
(6) Horizontal adjustment achieved by stations
107 of the base 106, etc.:
Horzintal (windage) adjustment is achieved mainly by the
features shown in Fig. 10, with various components having
reference numerals 106 through 130.

Briefly summarized to show the ease of horizontal
adjustment, the control screw 110 is turnable through its
head 112 to vary the spacing 125 between the sight bracket
82 and the adjustment base 106.
More particularly, the spacing 125 is achieved by
adjusting.either or both of the two stations 107 as described
above.
(7) Changes in laser beam characteristics:
As a desired supplement to the other concepts, preferably
in combination with one or more of them, the laser diode 64 is
desirably made with adjustable lens unit 180 to adjustably
produce an expanded target reflection dot.
The concept of adjustability of beam 66 as per
adjustment lens 180 is shown here schematically in Figs. 7 and
7A, however, for various mechanisms for altering the size
and/or shape of a projected beam are already well known except
that no combination of an adjustable lens unit for a larger target
of laser illumination is known to the Inventors, and the
laser art seems accordingly to consistently continue to desire
to shrinken the laser beam to achieve the extreme longer
distance, in present laser art, and the desired shrunken beam
66 is in contrast to any possibility of enlarging bhe beam 66
in the art of laser guidance.
45.
CA 02273116 2007-03-14
Operativity of the laser beam 66 alighment.is
achieved by energizing the laser 64 and aligning it with
.an arrow or other projectile, moving the containment box
20 in its vertical rotational path about the hinge connection
pin 144. The vertical rotational movement is illustrated
in Fig. 5. Adjustment procedure is now explained.
With the laser energized, when utilizing adjustment
procedures, the shooter rotates the containment box 20
hinged about the axle pin 144, and moves it in its 900
(Fig. 5) limited path, observing and adjusting the laser
beam 66 to be aligned with the center or axis of an arrow
or a projectile tube 170, by transversely adjusting the
adjustable base 106, by the manual manipulation of one or
both of the adjustment stations 107 provided in the base
106.
The centering is achieved by adjusting the adjustment
base 106 transversely in a direction to move the laser beam
66 towards or to the center of an arrow or projectile tube
170 as needed. _
Several adjustments or movements of the base 106 may
be required to achieve a fine tuned adjustment.

The present invention as detailed herein has advantages
in both concept and in component parts and features; for in
contrast to other articles known to the Inventors as to the
prior art the invention provides advantageous features which
should be considered, both as to their individual benefit, and
to whatever may be considered to be also their synergistic
benefit toward the invention as a whole:
a. Extremely accurate for precision shooting;
b. Even novices and youngsters can show great skill
in marksmanship, and even experienced marksmen can improve;
c. Ability to easily and quickly adjust for differences
in distance, elevation and ambient light conditions;
d. Adjustability for various shooting apparatus
factors and their special needs; -
e. Advantages without contrasting disadvantages;
f. Ability to range adjust and range indicate
distances;
g. Adaptable to various kinds and natures of
weapons;
47.
CA 02273116 2007-03-14
h. Provides special advantages of use to handicapped
sportsmen; and
i. Although technically sophisticated itself,
the sight unit is readily assembled as a manufacturing operation,
and is quite easily used by the shooter.
It is thus seen that a shooting attachment sight piece,
used according to the combination of inventive concepts and details
herein set forth, provides novel concepts of a desirable and
usefully advantageous article, yielding advantages which are
herein set forth.
In summary as to the nature of the overall articles'
advantageous concepts, their novelty and inventive nature is
shown by novel features of concept and construction shown here in
advantageous combination and by the novel concepts hereof not
only being different from all prior art known, even though other
aiming attachments for bow and arrow assemblies and for rifles and
shotguns have been known and used for scores of years, but because
the achievement is not what is or has been suggested to those of
ordinary skill in the art, especially realistically considering
48.
CA 02273116 2007-03-14
this as novel combinations comprising components which individually
are similar in nature to what is well known to many persons,
surely including most of the many makers of weapon apparatus for a
great number of years throughout the entire world. No prior art
component or element has even suggested the modifications of any
other prior art to achieve the particulars of the novel concepts of
the overall combinations here achieved, with the special advantages
which the overall combination articles provide;and this lack of
suggestion by any prior art has been in spite of the long worldwide
use of various types of shooting equipment.
The differences of concept and construction as specified
herein yield advantages over the prior art; and the lack of
this invention by the prior art, as prior art combinations, has
been in spite of this invention's reasonable operativity the and
construction once the concepts have been conceived, in spite of
the advantages it would have given, and in spite of the availability
of all of the materials to all persons of the entire world.
Quite certainly this particular combination of prior art
details as here presented in these overall combinations has not
been suggested by the prior art, this achievement in its particular
details and utility being a substantial and advantageous departure
from prior art, even though the prior art has had similar compnnents
49.
CA 02273116 2007-03-14
for numbers of years. And particularly is the overall difference
from the prior art significant when the non-obviousness is viewed
by a consideration of the subject matter of this sight device as
a whole, as combinations integrally incorporating features
different in their combination from the prior art, in constast to
merely separate details themselves, and further in view of the
prior art of shooting apparatus articles not achieving particular
advantages here achieved by this combination.
Accordingly, it will thus be seen from the foregoing
description of the invention according to the illustrative
embodiments, considered with the accompanying Drawings, that the
present invention provides new and useful concepts of novel and
advantageous articles, possessing and yielding desired advantages
and characteristics in formation and use, and accomplishing the
intended objects including those hereinbefore pointed out and
others which are inherent in the invention.
Modifications and variations may be effected without
departing from the scope of the novel concepts of the invention;
accordingly, the invention is not limited to the specific
embodiments, or form or arrangement of parts herein described
or shown.
