This invention relates to a toy cash register
having a supporting structure and including a plurality
of indicator targets and a plurality of keys for
individually raising the targets.
This is a division of copending Canadian Patent
Application Serial No. 223,904, filed April 7, 1975.
The manufacture o~ toys and educational devices
of the types which require manual assembly of larger numbers
of operative parts has become so costly due to rising labor
rates that many persons desiring to purchase them have
been prevented from doing so by the necessary high prices.
The overall objective of the present invention
is to provide an improved toy cash register from which
children can learn numbers and the mathematical operations
of change making while at play, and which accurately
simulates the action of acutal cash registers used in
trade, but which is manufacturable at substantially lower
cost than known types that are capable of similar performance.
The present invention resides in a toy cash
register having a supporting structure, a plurality of
vertically slidable indicator targets, a plurality of keys
~ for individually raising the targets, and means for
- releasably holding the indicator targets in raised position.
The invention includes an abutment portion on each target,
a target latch member rockably mounted in the supporting
stru~ture, and a plurality of fingers on the latch member
individually aligned with the paths of movement of
corresponding ones of the abutment portions on the targets.
Each finger is inclined upwardly and angularly toward its
corresponding target and has a free upper end which is
movable toward and away from a position corresponding to
underlying relation to the abutment of the corresponding
'~

raised taxget in response to rocking movement of the
latch memher. Each o~ the fingers is stiff enough in a
vertical direction to support a target when undercngaged
with the corresponding abutment, but is yieldable enough
in a horizontal direction away from the target to flex
away from its target far enough to permit the abutment of
a target which is being raised to pass the same without
thereby transmitting enough torque to the latch member to
rock the other fingers away from underlying relation to
other raised targets.
In a specific embodiment of the invention,
the finger may be integral extensions of the latch member.
Other objects and advantages will become apparent
upon consideration of the present disclosure in its
entirety.

The housing of the improved cash register may be
formed of sheet metal, and comprises a drawer compartment
portion generally designated 50 formed as an inverted box a,~nd
serving as a base for the machine. The drawer 51~ shown closed
in Fig. 3, is pro~ectable in the usual fashion when released,
as shown in Figs. 7 and 9. The bottom of the drawer compart-
ment or base 50 is closed by a sheet metal bottom plate 52 upon
: . .
which the drawer rests.
A main casing portion 54, also formed of sheet metal,
is upstanding from the base 50. Casing 54 is comprised of a
front portion 56 and a rear portion 57, with the latter of
which the side walls 58,are integral. The sheet metal compo-
nents 50, 5Z, and 54 are secured together in a convent~ional
manner as by suitable tongue and slot fastening meansj indi-
cated at 55, 55'. The sloping front wall 56' pf the ront
portion 56 of the casing 54 ~onstitutes a keyboard section and
is provided with two transuerse rows of openings tundesignated)
for plunger-type pushbuttons 60, 61 which normally proJect
therefrom.
The pushbuttons 60, 61 are formed integrally wi~h
corresponding indicator target portions 70 and 71 and with
connecting and hinging portions by which these elements are
dg/ ~ -3-
(J
~ 0647~Z
supported and by means of which motion is transmitted from
the pushbuttons to the indicator targets. These parts are
formed as a single injection molded plastic component, gener-
ally designated 75, preferably of a plastic of the polyolefin
family, e~g., polypropylene or ~astman's "Polyallomer", which
are well-known plastics which in thin sections can be bent,
and function practically indefinitely as a hinge without rac-
turing, whereas in thicker sections they are quite rigid and
function effectively in structural components.
The member 75 will be referred to as the key-target
assembly (although it is actually a single unitl as noted).
Its construction is best shown in Figs. 16-18. As there shown,
nine pushbuttons and targets axe incorporated, although this
is of course subject to variation. Each pushbutton portion
60, 61 has an integral supporting stem portion 76, 77 which is
connected by a thinned hinge portion 78 to another thicker
(and therefore stiffer) portion 80 which constitutes a lever of
.
the first class. Each lever has a shorter arm 81 to which the
hinge portion 78 is connected and a longer arm 82 connected by
a second thinned hinge portion 84 to a stem portion 85 which
carries the indicator target 70 or 71, as the case may be.
All of the targets are molded as a single panel, and subse~uent-
ly cut. Each lever also has a pair of rigid projections 87, 88
extending laterally from both sides thereof, continuations of
the projections being extended rearwardly along side the lever
and having transversely aligned thinned hinging portions 89
defining the fulcrum of the lever. Rearwardly of the fulcrum
hinge portions 89 the material is continued in a further thick-
ened stiff section 91 defining a support arm which terminates
in an integral supporting pin portion 90. It will be seen that
e~cept at the two outer ends of the assembly/ each of the pin
portions 90 is connected to and serves to support two adjacent
levers.

The key-target assembly and other supporting and
operative components are preassembled before installation there-
of in the housing structure. The method of assembly and instal-
lation will bs described hereinafter, the parts will first be
described with reference to their installed operative posi-
tioning.
A supporting frame generally designated 95 is se-
cured to the top of the base 50 inside the casing 54. The
construction oE frame 95, which I have formed of molded poly-
styrene, is best shown in Figs. 10 to 15, inclusive. A flat
; medial portion 96 of frame 95 lies on wall 53, extends trans-
versely of the casing 54, and carries along its rear edge a
series of upstanding tubular socket portions 98 open at the
top to receive the supporting pin portions 90 of the key-target
assembly, which pin portions are pressed into the sockets and
may be held by fric~ion. Along its front edge, frame 95 is
provided with a pair of spaced paral:lel upstanding flanges 101,
102.
A multi-fingered comb-type retractor leaf spring
generally designated 100 is supported by the flanges 101, 102,
The retractor spring is preferably shaped so that two can be
pressed without wasté from a single rectangular blank, as is
brought out by the broken line in Fig. 26. ~One of the fingers
103 is provided for each pushbutton-target pair, the fingers
being spaced conformably to the spacing of the pushbutton stem
portions 76, 77 and extending rearwardly beneath the extrem-
ities of such stem portions as best shown in Figs. 3-7. The
spring 100 is flat in its relaxed condition but is held in an
arched form by the flanges 101, 102, and by its confinement
beneath the thickened lower extremities of the stems 76, 77.
The fingers of the spring extend through locating notches 105
between the upwardly projecting parts 104 of a crenelated top
dg/ l,;; -5-
~.J
~L069~7~
formed on flange 102, the straight rear edge of the spring
being wedged against the rear wall of flange 101. The ends of
the fingers 103 extend rearwardly beyond the extremities of
the stems 76, 77 and overlie a raised shoulder portion 106
formed on frame 95 forwardly of but close to the socket portions
98. The upward bias effect of ~he spring fingers 103 urges
the longer forwardly-projecting arms 82 of the levers 80 up-
wardly, thereby biasing the stems 7~, 77 and their pushbuttons
upwardly and outwardly with respec~ to the keyboard section
56' and also urging the targets downwardly. When a pushbu~ton
is depressed fully, as shown in Fig. 5 at 6i, the lower corner
portion as 107 of the corresponding stem, as i6, slides along
the spring finger 103 while-depressing it, and forces the tip
of the finger downwardly against the shoulder 106. In the fully
depressed position of the button the corner 107 thereby dis-
torts the spring finger to S-shape, increasing the elastic
modules of the spring so that when the target and button are
subsequently released the target and pushbutton will be re-
turned in a smart, quick fashion which overcomes any delay or
slowness of action which might be caused by the memory factor
of the plastic. A hammer portion which is a dimple 83 of
solid plastic i9 formed at the end of each lever arm 82 and
projects downwardly in position to strike the top waIl 53 of
base 50 when the target drops. Due to the substantial res-
onance factor of the sheet metal wall 53, this causes a noise
which adds interest to the use of the machine.
The frame 95 is secured to the flat top wall 53 of
the base 50 by means of integral hooks 111 and 112. The hooks
111 are formed as short rigid downward extensions of the body
of the frame 95 along its rear edge and project through suit-
ably positioned openings (undesignated) in the top wall 53 of
the base. The hooks 112 are formed on the lower ends of spring
dg/~ 6-
~647~2
arms 114 which extend forwardly and downwardly from the upper
edge of front flange lOl and proj&ct through openings (undes-
ignated) in top wall 53. The openings for the hooks 111 and
112 are so positioned that the hooks 112, ~hich have inclined
front walls, must be cammed toward the rear in order to enter
the openings, whereafter the arms 112 snap forwardly and lock
the frame 95 in position. Integral projections 113 on the
bottom o the frame 95 extend into locating holes (undesignated)
in top wall 53 of base 50 to prevent the frame from moving for-
wardly far enough to free the retaining hooks 111 after
installation of the frame.
The stems 85 and their attached target portions 70
and 71 are straight and extend upwardly from the hinge portions
84 at their lower extremities through a target guide member 120
located in the top wall 115 of casing 54. When the targets
are moved upwardly to the raised position they are visible
through the window member 122, while when in the lowered posi-
tion they lie substantially below the top walls 115, 118 of
the casing 54 and target guide 122, respectively, so ~hat the
indicia 116 thereon are obscured from view.
The target guide has been formed of a unitary poly-
styrene molding. A relatively large rectangular opening 12L
in top wall 115 is defined by the rear edge of the front c~sing
member 56, the forwardly inturned upper flange 57' of casing
part 57, and the edges of inturned flanges 58' of end walls 58.
Opening 121 is substantially filled by the flat top wall por-
tion 118 of'the target gulde, although the target guide is
enough smaller front to bac~ to permit its insertion in opening
121 by shifting it to the front of the opening, to permit the
interfitting oE tongue parts (to be described) on the casing
and target guide. The wall 118, whi~h is substantially co-
planar with the top wall 115 of casing 5~, has vertical down-
turned front and rear marginal Elanges 11~ and vertical end
~ 7-
~Cl 647~2
hanger walls 155 which position it in the horizontal plane.
The inverted generally box-shaped transparent win-
dow member 122 has its open-bottomed walls proportioned to
project between and substantially fill the space between the
perimeter of the target guide 120, defined by flanges 119 and
end walls 155, and the walls of the opening 121, The rear
portion of top wall 115 of the casing section 54, defined by
the flange 57', has tongue portions 126 coplanar therewith
and which project forwardly from the rear edge of the opening
121 and which underlie the top wall ll~ of the target guide
120 along the rear edge thereof. The front portion of top
wall 115, defined by the rear edge of front wall 56, also has
tongues 127 pro;ecting rearwardly horizontally, but stepped
downwardly from, the front edge of the opening 121. Tongues
126, 127 also underlie the bottom edges of the front and rear
walls of the window member 122, which is formed of a tough
t~ansparent plastic such as a molded polystyrene copolymer.
In the areas between the tongues 126, the rear edge of the
target guide 120 has depressed rearwardly extending horizontal
tongue portions 128 u(nderlying the wall 115 rearwardly of the
opening 121 and preventing upward displacement of the target
guide. Hooked flange por~ions 129 on the lower edge of rear
wall 125 of the window member 122`also project rearwardly and
underlie the top wall 115 behind the rear edge of opening 121.
Hook portions 129~extend between the tongue portions 128 and
the lower surface of top wall 115. In the areas between the
front tongues 127 on the casing, the target guide 120 is
provided with two integral downwardly-displaced forwardly-
extending horizontal tongues or flanges 130 each of which has
a longitudinal slot 131 therein. The flanges 130 extend for-
wardly beneath the downturned front edge wall 116 of the
opening 121, thereby preventing upward displacement of the
target guide 120.

The front wall 124 of the window member has portions 123 which
project downwardly through the slots 131 and carry at their
lower extremities forwardly hooked retaining portions 135
which underlie the flanges 130 forwardly of the slots 131,
thereby retaining the window member 122. The.window member
locates the target guide 120 against unwanted horizontal shift-
ing and maintains the respective tongue portions in their inter-
locked retaining relationship.
The top wall 118 o~ target.guide 120 has a longi- -
10tudinal vertical slot 136 through which the target portions
70, 71 are vertically slidable between upwardly projected
raised positions, as shown in Fig. 5, in which the indicia 116
thereon are visible through the window, and lowered positions,
as shown in Figs. 4, 6 and 7 wherein the indicia lie below the
opaque top walls 118, 115 and are hidden from view.
The above-described key-target assembly is also
described and is claimed in above-mentioned Parent Application
Serial No. 223,904 and in copending Canadian Divisional
Application Serial No. 314,117, filed October 24, 1978.
Integrally projecting from the front surface of
each target is an abutment generally designated 140 having a
sloping top surface 141 inclined outwardly and downwardly at
an acute angle to the face of the target, and a lower surface
142 inclined rearwardly~and downwardly at an obtuse angle to
the face of the target.

A latch member is provided, the details of construc-
tion o which are best shown in Figs. 20-22, consisting of a
rockable frame generally designated 150 éxtending transversely
and parallel to the plane of the targets and having integral
fingers 152 rockable therewith in such manner that the upper
horizontal end portions 153 of the fingers are movable to and
from a position lying in the path of the respective abutment
portions 140. The frame 150 has integral coaxial stubshaft
portions 154 at i~s ends by means of which it is trunnioned
in the end hanger walls 155 ,which are suitably apertured
therefor as indicated at 156.
The latch member frame 150 is biased, in a clockwise
direction as viewed in Figs.~4 to 6 inclusive, to yieldably urge
it to the holding position wherein the fingers 152 are ih the
interfering position. In such position, the lower wall 142 of
the abutment 140 of any target which is raised, will overlie
the top edge 153 of the corresponding finger 152 of the latch
member, the target thereby bsing held in the raised position.
The latch member is biased to such position by a wire spring
160 which is straight in the relaxed position, and which is
hooked at its ends in pocket-defining portions 161 formed integ-
rally with and pro~ecting forwardly from the ends af the target
guide member 120. The central po~rtion of the spring ~ire 160
extends through a hook 162 on the latch member 150 located for-
wardly of the fulcrum axis defined by the stub-shaft portions
154, so that the spring biases the fingers rearwardly.
The latch member is formed as an integral injection
molded polystyrene unit. The fingers 152 are thin enough so
that they are relatively flexible, and the strength of the bias
spring 160 and the proportioning of the abutments 140 are such
that the outward camming effect of the abutment 140 of a
target which is being raised does not rock the latch member
dg/`\~; 9-
~ ~06~7~3Z
(counterclockwise, as viewed in Figs. 4-6) far enough to cause
any other fingers which may be underlying a raised target to
move outwardly far enough to free the abutment and allow such
other raised targe~ or targets to drop. Thus any number of the
ta~gets may be raised in sequence without thereby releasing any
of the other targets.
In order to permit the operator to release the targets
when desired, ~he latch frame 150 is provided with a lever arm
170 inclined forwardly and downwardly therefrom at one end and
having a slot 171 therein. A pushbutton 175 which proiects
through and above a sui~ably-positioned opening (undesignated)
ln the keyboard sec~ion 56 has a plunger portion 177 with a
reduced lower extremity 178 which extends into the slot 111.
The pushbutton 175 and plunger 177 are normally held in the
raised position by the biasing spring 160, but depressing the
button rocks the latch mem~èr in a direction to move the fingers
away from the targets far enough to free the abutment and permit
raised targets to drop.
Another pushbutton 180, similarly mounted in an
(undesignated) suitably-positioned opening in the keyboard
section 569 has attached thereto a plunger 1819 the lower extrem-
ity of which pro~ects through and is guided by a slot (undesig-
nated~ in the top wall 53 of the base 50. A crank, generally
designated 182, is rookably supported in a downwardly-opening
slot 184 in the bottom of the frame 9!5 and has one arm 183
pivoted in the lower portion of the plunger 181 and a second
arm 185 which projects rearwardly from the frame member 95
through a slot 196 in one of the socket portions, designated 98'
in Fig. 15,~ and is hooked in a 810t 198 in a drawer latch arm
generally designated 200.
The drawer 51 is biased outwardly by a wire spring
202 which is looped to substantially circular shape but which
when the drawer is closed is distorted to oval shape, as shown
~1 - 1 o-
~.,
96~7C~
in Fig. 9, by the depending front wall 204 of the drawer.
The spring 202 lies beneath the drawer and has its two spaced
rear ends hookéd into and retained by tongues 205 struck up
from bottom plate 52. The tongues 205 have front edges which
incline rearwardly at approximately 60 ~oward the top, and
the hooked ends 203 of spring 202 are of generally S-shape, as
shown in Fig. 8. The expansive force of the spring causes the
parts thereof near the S-bend, which parts are forced against
the inclined front edges of the tongues 205, to exert a cam-
like force urging the spring to and holding it in an upwardly
inclined position, as nearl~ perpendicular to the inclined
edges as possible. The spring is thereby kept in effective
engagement with the drawer and prevented from projecting out
underneath the drawer front.
The drawer latch arm 200 comprises a flat sheet metal
member lying on a central vertical plane and extending toward
the front and rear of the assembly beneath the top wall 53 of
the base. Near its forward end the latch arm has an upwardly
and forwardly inclined tongue 208 hooked in a slot (undesignated)
in wall 53. The ~uncture of tongue 208 with the straight bottom
portion of the latch arm 200 defines a pivot for vertical swing-
ing movement of the arm. The rear end of the latch arm has an
upwardly extending tongue 210 which extends through and is
guided in a slot in the wall 53 and is notched at 198 ~o receive
the crank arm 185. A mid portion of the latch member 200 has
an integral tongue 212 which extends upwardly through a slot-
like opening 225 between two laterally spaced downwardly pro-
jecting flanges 214, 215 integral with frame 95, and through
upwardly extending coplanar continuation flanges 214', 215',
also integral wlth frame 95. The downwardly extending flanges
214, 215 project through an opening 218 in wall 53, and coact
with the flanges 214', 215' to define slide bearings for the
sheet metal latch arm 200, which is thereby ef~ectively held

against substantial lateral movement and accurately guidea in its vertical
movement. In Fig. 8 the central one of the spring fingers 103 is broken
away to show the positioning of flanges 21~', 215' and the aperture 218.
A shoulder 220 on the rear of the latch arm 200 is movable vertically to
and from an interfering position with the rear wall 222 of the drawer 51
by rocking movement of the latch member in a vertical plane around the
plVOt axis defined by the front tongue 208.
The flanges 214', 215' extend upwardly to a position higher
than that occupied by the top edge of the tongue 212. A transverse slot
227 extends downwardly through flanges 214', 215', intersecting slot 225.
A wire spring member 226, which is straight when relaxed, is arched over
the top edge of the tongue 212 within the slot 227, and is confined by
looped retainers 228 and abutment flanges 229 formed on the frame 95.
Spring 226 biases the rear end of the latch down to the drawer-holding
position, and the pushbutton 180 to the raised position. As the drawer
is moved to the closed position, the latch arm, which has a stxaight lower
edge, is cammed upwardly by the rear wall 222 of the drawer, and when the
.
drawer reaches the fully-closed position the rear of the arm ves down-
wardly so that the shoulder 220 then retains the drawer in the closed
position. Outward movement of the drawer is limited by an abutment tongue
251 depending integrally from the bottom of the drawer. The drawer is
also formed as a unitary molded plastic member. A tongue 252 struck up
from the bottom plate 52 blocks the abutment 251 to limit the projection
of the drawer. The drawer is provided with a transverse central partition
253. The partition 253 and rear wall 222 are provided with aligned vert-
ical slots 256, 257, respectively, which are narrow and of a width to
just slidably receive the latch arm 200. The latch arm thus serves as
a guide to center the drawer in the front drawer opening. Rounded hold-
down tongues 258 struck downwardly from wall 53 and positioned to overlie
and prevent upward ~ovement of the back wall 222 of the drawer insure
proper disengagement of the latch bar when button 180 is depressed.
When the drawer is fully closed, the abutment 251 which has an
dg/ , ,,; -12-
1~647(~
inclined rear edge 25~ lies to the rear of a spring clapper
arm 265, also of molded plastic, for a bell 266. The clapper
arm and bell are riveted to the top of bottom plate 52
under the raised bottom of the drawer. In moving forwardly,
the abutment 251 moves the clapper arm 265 forwardly until
the abutment slides past the free end of the clapper arm,
which then moves rearwardly, undex the spring effect of its
own resiliency, and a metal button 268 thereon strikes the
bell.
: 10 It will be noted that the ears 205 which secure
the ends of the looped drawer spring 202 are spaced on
either side of the centerline, 50 that the abutment 251 can
: move between them, to and from engagement with the abutment
252. The spring 202 reaches the limit of its expansi.on
before the drawer reaches the full~ open position, but the
inertia of the drawer carries it to the fully open position.
The position and length of the clapper arm 265 are such
that the abutment 251 moves free o the clapper arm whi3.e
the spring is exerting power on the drawer, or close to the
limit of expansive movement of the spring.
The above-described drawer construction is also
- described and is claimed in copending Canadian Patent
Application Serial No. 267,697, filed October 2~, 1978.
Assembly of the cash register is carried out in
the following manner: The~target guide 120 and targe latch
150 with targèt latch spring 160 are preassembled with the
window 122 in the upper casing 54. The key-target assemb].y
75 and retractor spring 100, together with the drawer latch
bar spring 226, and crank 182 are also preassembled with
frame 95. The metal upper casing 5~ with the target guide
and target Latch therein are supported in an inverted
- 13 -
sb~
1~647~
position. The key-latch assembly 75 i5 then installed in
the inverted upper casing, taryets 70, 71 bein~ passed
through slot 136 in the target guide 120 and the push-
buttons 60, 61 being passed through their respective
openings in the keyboard section 56. Drawer release button
180 and target latch release button 175 are inserted, an~
are held from falling through their respective openings in
the keyboard section 56 by flanges at the lower ends of the
pushbutton parts. Plunger 181, which was previously inserted
and held in a slot (undesignated) in the pushbutton 180,
has a hole (undersignated~ which is hooked over the inturned
end of arm 1~3. The base 50 is then positioned. The hooks
111 are passed through their slots, and a hooked tool (not
shown, but comprising a simple double hook, as will be
~` obvious) is then projected through a pair of openings
274 in the wall 53, and through the aligned openings 275 in
the wall 96 of frame 95, and usecl to pull the frame against
the (inverted) top surface of wall 53. The hook portions
112 at such time snap through their receiving slots and
move forwardly to lock the operative parts to the wall 53.
The tongues 55 are then bent to lock the upper casing portion
54 to the base 50 and retain the operative parts. The
looped spring 202, bell 266 and clapper 265 are pre-
assembled to bottom wall 52 of the drawer compartment, and
the bottom wall is then secured by means of the tongues 55'.
The drawer 51 is installed by pushing lt into place. The
tongue 252 and the bottom wall 52 yield sufficiently to
permit the abutment 251 to pass thereover, but return to posi-
tion and will not thereafter permit the escape of the drawer~
