VOTING MACHINE Filed Jan. 16, 1941 ATTORNEYS Patented Feb. 3, 1942 VOTING MACHINE Ransom F. Shoup, Ardmore, Pa., assigner to The Shoup Voting Machine Corporation, Philadelphia, Pa., a corporation of Delaware Application January 16, 1941, Serial No. 374,621

y(Cl. 235-1'44) 9 Claims.

This invention relates to counters and more especially to counters of the type covered by Ransom F. Shoup United States yPatent No. 2,140,336, such counters being designed for use in voting machines of the type disclosed in Shoup et al. United States Patent No. 2,054,102.

In Shoup Patent No. 2,140,336 there ,is disclosed a counter consisting essentially of a master gear oscillatable over a denite path and a plurality of number wheels in combination with a reciprocable pinion assembly for driving the units wheel by the master gear for vote-registering purposes and for locking the units wheel against operation except through the medium of the master gear. A shield overlies the counter and is provided with a slot through which are visible the digits on the number of wheels. Also, the structure of the counter is such that it can be reset to zero in an easy and expeditious manner merely through the operation of efectingrotation of the units wheel. However, the resetting arrangement shown in said patent is such that during a resetting operation, the pinion assembly is released from the units wheel thereby making it possible to rotate the latter independently of the former and to locate the units wheel with its numbers so oriented with respectto themaster gear and shield slot that after one or more operations of the counter, the portion of the units wheel in register with the shield slot will be f' the space between two digits rather than a digit.

An object of this invention is an improved counter which is of such structure that the units Wheel is at al1 times operatively connected to the pinion assembly so that whenever the master? gear lies at one end of its path, the units .wheel has one of its digits in full registration with the shield slot.

Other objects, novel features and advantages of the present invention will become apparent from the following specication and accompanying drawing, wherein:

Fig. 1 is a section substantially on `the line I-I of Fig. 2.

Fig. 2 is a fragmentary front elevation of a counter column of a Shoup type voting machine;

Fig. 8 is a section on the line 8-8 of Fig. 5.

In this specification there will be described mechanism common to said Patents No. 2,054,102 and 2,140,336 and the present application'with ber '46.

the reference numerals used to designate the mechanism illustrated in the drawing corresponding to those of said two patents so as to make clear the relation of the present improvement to the former structures.

A vertical partition plate 39 supports a plurality of vertical channel members 46, but for vthe sake of simplicity only one such channel member is illustrated. Each channel member has its open portion facing the partition plate and vencloses a column of counters later to be described. Also each channel member is provided with flanges 46a through which extend spindles 38 provided with operating handles 39 and in the cross yplate 4Gb of the channel member 46 are -provided a plurality of horizontal slots 46c. On

the opposite side of the partition 39 from the channel members 40 is arranged a vertical bar `54 supported as described in Patent No, 2,140,336

49 to effect horizontal reciprocation of the latter,

there being a bar 49 for each horizontal row of spindles.

On each spindle 38 is provided a pinion I0 which meshes with teeth on a master gear I I supported by a shaft I2 journalled in the sides of the channel member 46 in horizontal alinement with a slot 46c. On the shaft I2 are also supported digit wheels I3a, i317 and I3c of which Ita is the units wheel and the other two digits wheels are connected therewith inthe usual manner through pinions I4 rmounted on a shaft .I5 which is supported by the sides of the channel mem- `The units wheel Ita is provided with twenty teeth I0 and on the shaft I5 is journalled an eight tooth .pinion II in mesh with the teeth I6. A four-tooth pinion I8 is formed on ythe end of a stud I9 extending from pinion Il. The teeth of the pinion I0 are so arranged as to engage the master gear Il as shown in Figs. 1, 3 and 6 to lock the pinion against rotation except as later to be described. The relation of the units Wheel and pinion assembly is such that whenever the pinion I8 is in locking relation on the master gear II, a digit is alined with the slot 46c.

The end of the master gear II adjacent the .units Wheel I6 is recessed at 20 to permit movement of the pinion I1 along the shaft I5 and in the recess are provided two transfer teeth 2l ,adapted to mesh with the pinion II when the .latter is so arranged as to extend into the recess,

'I'he master gear II is provided with a slot 22 extending from the toothed end thereof and having its inner end axially offset from the adjacent end of the recess 2D, the slot 22 being in alinement with the groove between the teeth 2| and terminating short of the transfer teeth to form a bridge therebetween. The recess 20 is of insuflicient axial width completely to receive the pinion I1 thereby preventing disengagement of it from the teeth I6 and the distance between the opposing faces of the pinions I1 and I8 is slightly less than the distance from the inner or left end of the slot 22 to the face of the master gear adjacent the units wheel. The pinion I1 will be engageable by the teeth 2| whenever a tooth of the pinion I 8 is insertable into the slot 22 and the pinion assembly will therefore be positively rotated to cause the tooth of the pinion I8 to move into the slot 22 upon rotation of the master gear II.

Means are provided for shifting the pinion assembly I1, I8 and I9 along the shaft I5. A vertical channel member 23 is attached by bolt 23a to the bar 49, the bolt 23 passing through a horizontal slot in the partition 39. A lug 24 is struck up from the channel member 23 and a slide 28 having an upturned end 29 is supported by the channel member with the upturned end 29 being arranged exterior of the flange. A spring 40 is associated with the slide 28 and has one end attached to the upturned end 29 with the other attached to the opposite flange of the channel member whereby the slide is normally maintained with the end 29 in contact with the channel flange al1 as is set forth with more particularity in said Patent No 2,140,336. The lug 24 and end 29 constitute yokes straddling the pinion assembly and upon movement of the channel member 23 the pinion assembly is correspondingly moved. Each lug 24 and end 29 is recessed to receive the shaft I and limit movement o1' the pinion assembly away from the units wheel.

In the master gear is arranged a recess IIa of suicient size to receive the teeth of the pinion I8 to permit rotation thereof with consequent unlocking of the pinion I1. The location of the slot IIa is such that when the slot receives a tooth of the pinion I8, the pinion I1 is fully moved into recess 20 and, as previously mentioned, the width of the pinion I1 is such that it cannot be moved out of mesh with the gear I6. The spacing between the slots 22 and Ila equals the width of a tooth 2| and is of sufficient size that with the master gear in unvoted position the pinion I8 may rotate freely.

In Figs. 1, 3 and 6, the pinion assembly is shown in counter-locking position, this being the position of the pinion assembly before a voter enters the voting machine and with the curtains of the machine open. In this position, units wheel I3a is held against rotation by reason of the locking engagement of the teeth of pinion I8 with the periphery of the master gear II which prevents rotation of the pinion I8. Therefore, as the pinion I1 is in mesh with the gear I 6, rotation of the units wheel I3a is prevented. Upon closure of the curtains the bar 54 is moved to the right (Fig. 1) a predetermined distance carrying with it the bar 49 and the channel member 23, all as described in said Patent No. 2,054,102. Such movement of the channel member 23 causes the yoke member 24 to move the pinion asembly I1, IB, I9 into the position shown in Figs. 4 and 7.

In this position, the pinion I1 is still in mesh 75 with the teeth I 5 but projects into the path of the teeth 2I, and rotation of spindle 38 to the dotted line position of Fig. 1 effects rotation of the master gear II to move the slot 22 into position to permit projection thereinto of a tooth of the pinion I8, thereby allowing rotation of the pinion assembly by the transfer teeth 2| to eifect one-tenth of a revolution of the units wheel to advance the wheel one digit. During the above-described operation, the master gear II is rotated to such an extent that the tooth of pinion I8 which entered the slot 22 is moved out of said slot and it, together with the succeeding tooth of said pinion is again in locking relation to the master gear to prevent rotation of the pinion I1, After the voter has operated the proper spindles to register his vote, he opens the curtains as described in said Patent No. 2,054,102 thereupon causing return of the bar 54 to its original position with the accompanying return of the pinion shifter and pinion assembly to original position, leaving the units wheel in the position to which it had been advanced by operation of the spindle. After the pinion assembly has been returned to original position, the spindle and master gear are returned to the position shown in Fig. 1 by mechanism fully illustrated and de scribed in said Patent No. 2,054,102.

In the event that the voter has left a spindle in a position of incomplete operation, possibility of injury to the counter during the return of the pinion assembly, master gear and spindle to original position is avoided. Under such conditions, a tooth of the pinion I8 will remain sufciently projected into the slot 22 to prevent full return movement of the pinion assembly thereby preventing disengagement of the pinion I1 from the teeth 2I of the master gear. Thus, when the master gear and spindle are returned to their original position during curtain opening operation of the machine, the teeth 2| will rotate the pinion I1 thereby causing the tooth of pinion I8 to move into the slot 22 without any binding action. At the same time the units wheel is likewise returned to its original position, and

injury to the counter is prevented.

When the master gear has been returned to its original position, the tooth of pinion I8 will have completely moved out of the slot 22 thereby permitting full return movement of the pinion assembly to its original position under conditions which cannot cause injury to the counter. The spring 40 permits relative movement of the slide 28 and the channel member 23 so that if a pinion assembly is held against full return movement as above set forth, the channel member may be returned to its original position without injury either to the pinion assembly or the pinion shifte1'. 'The spring will yield sufliciently to permit the necessary relative movement of the slide and channel member when the above-described condition arises.

When it is desired to reset the counters to zero, the bar 54 is operated as described in Patent 2,140,336 to move the pinion assembly into the position shown in Figs. 5 and 8 with the pinion I8 in alinement with the recess Ila. The units wheel of the counter is now free to rotate in the reverse direction and may be so rotated merely by wiping the counter face with a brush or other suitable instrument which frictionally engages the units wheel The front face of the channel member is depressed at 32 so as to permit projection through the channel face of the units wheel teeth. Standard means are provided for preventing reverse movement 'of the digit wheels beyond the positionin which all three digit wheels have their zeroes in register with the slot '460, -seePaten't No. 2,140,336. `After the counters have been reset to zero, the pinion assembly is returned to the position shown in Fig. 3.

Should the "operator in resetting the counter leave a units wheel in such position thatits Zero does not fully register with the slot 460, ythe pinion I8 will have one of its teeth projecting 'into the slot Ila (see Fig. 8) thereby lpreventing Ureturn lmovement of the spindle assembly to 'the Fig. 3 position. The bar 54 and the bar 49,h0wever, will return to proper poistion due Ato the stretching of the spring 4U. With the counter in this condition, rotation of the master gear 'by operation of the spindle from unvOted to voting position has no effect on the units Wheel until a tooth 2l engages a tooth of the pinion I1 after which the master gear and units wheel rotate in unison. With one or both teeth 2| in mesh with the pinion I'I, the units wheel I6 is properly lined up with respect to the master wheel so that after maximum rotation of the master wheel, the number I on the units wheel registers with the slot 46c. Rotation of the pinion I1 as just described also causes rotation of the pinion I8 to remove from the recess IIa the tooth projecting thereinto and to bring another tooth of the pinion I8 into the slot 22, thereby permitting return of the pinion assembly to the position shown in Fig. 4 under the influence of the spring 40. Return of the master gear Il to its initial position leaves the units wheel in position with one of its digits in register with the slot 46c, the particular digit thus in register being dependent upon whether or not the master wheel is returned to original position by the manual operation of the spindle 38 or whether its return is a part of the curtain-opening operation of the machine.

In Fig. 2, two spindles and their associated counters are illustrated, The upper spindle is in unvoted position corresponding to the position shown in full lines in Fig. 1, while the lower spindle is in voted position corresponding to the dotted line position of Fig. 1. In each position of the spindle, a units digit is in register with a slot 46c. Before any actuation of the counter, this digit is zero as indicated in connection with the upper spindle, while after the rst movement of the spindle 38 into voting position, the number is 1 as indicated in connection with the lower spindle. Whether or not the resetting operation has placed the units wheel zero directly in register with the slot IISG, the first operation of the spindle 38 will result in the digit I of the units wheel being brought into register with the slot 46c and thereafter a units wheel digit will be in register with the slot 46a with the spindle either in its unvoted position or in its voted position.

It is of course understood that various modiiications may be made in the structure above described, without in any way departing from the spirit of the invention as dened in the appended claims.
