TO WHOM IT MAY CONCERN:
Be it known that I, Edward Humpert, a resident of the City of St. Charles,
County
of Saginaw, State of Michigan, a citizen of the United States of America have
invented a
new and useful device that is an
ARCHERY CROSSBOW ASSEMBLY
that is described in this specification.
This application claims priority from US Provisional Patent Application No.
61/215,898 filed May 11, 2009.
BACKGROUND OF THE INVENTION
The applicant is unaware of any prior art that incorporates a peep sight and a
range finder into the sight of a crossbow.
THE INVENTION
The invention is an archery crossbow assembly comprising in combination: a
gunstock that has a near end and a distal end; an archery crossbow assembly
that has an
archery bow mounted on the gunstock near the distal end; a bow string mounted
on the
bow with a stopping means for the bow string when the bow string is in a
firing position,
and a peep sight. This peep sight is mounted on the gunstock near the near end
of the
gunstock. The archery crossbow assembly also has a front archery sight that
has a front
surface and is mounted on the distal end of the gunstock, and, a trigger
mechanism for
releasing the bowstring. There is a range finder mounted on the front surface
of the front
sight.

DETAILED DESCRIPTION OF THE DRAWINGS
Figure 1 is a side view of the crossbow assembly 2. The cross bow assembly 2
has
a front sight 4 equipped with a ranger finder 6. An arrow channel 8 has a near
end 10 and
a distal end 12. The near end 10 has limb supports 14 that support limbs 16.

Also the rear
sight 28 comprises a vertical peep slide frame 38, a vertical peep slide view
hole 40 and a
male dove tail 42.
Figure 2 is a full front view of the vertical peep sight frame 38 showing the
vertical peep slide view hole 40 and the adjustment holes 36.
Figure 3 is an end view of vertical peep sight 38 showing a male dove tail 42.
Figure 4 is a front view of the peep sight frame 38 featuring adjustment holes
44
and view hole 46.
Figure 5 is a front view of the mounting plate 48 featuring a threaded
mounting
hole 50 and windage calibration markings 52.

Figure 11 is a side view of the front sight 4 including a fiber optic channel
with
tubing and the fiber optic channel in the range finder 6.
Figure 12 is one embodiment for the front sight 4 with a sight pin bar 74,
fiber
optic channels 76, fixture holes 78, and fiber optic wrap tabs.
Figure 13 is a side view of the front sight 4 featuring mounting holes 82 and
fiber
optic channels 84.
Figure 14 is a rear view of the range finder 6 of the cross bow assembly 2.
This
view shows both the quick range back bar 86 and the quick range belly bar 88.
Also
present is the fiber wrap tabs 80 and a threaded hole 90 for a light kit.
Figure 15 is a rear view of the range finder 6 without the back 86, and the
belly
88, bar assembly. Again visible are the wrap tabs 80 and the fixture hole 90.
The crossbow assembly of this application combines the use of a rear peep
sight
with a front sight that incorporates a quick view range finder. The user can
quickly raise
the crossbow, look through the peep, and determine the distance of the target.
This will
enable the user to have the knowledge that the target distance is precise and
not just an
estimate. The sight also has a windage indicator that will allow compensation
for wind in
the range that is the distance between the shooter and the target, giving even
more
accuracy than is obtained with standard sights. The sight is also equipped
with the ability
to be lighted using fiber optic technology.
The sights of this invention may be used on any weapon.
