ABSTRACT OF THE DISCLOSURE A compact, lightweight, manually operated voting machine with provisions for straight ticket, selective and write-in voting, and for choosing two or more candidates from a list of several running at large; with provision for recording each voters choice on a punch card for computer counting, and including a mechanical counter automatically totalling the votes for each candidate for confirmation of the punch card count.

This invention relates to voting machines and is directed to improvements in the construction illustrated and described in my prior Pat. No. 3,168,240 which was issued on Feb. 2, 1965.

My prior invention accomplished the object of listing candidates for more than one office in a single column, thus substantially reducing the weight and bulk in comparison to existing voting machines. It also employed a very compact selector mechanism, whereby but one vote out of each slate of candidates is allowed, which helped to provide a relatively small and economical machine. My present invention further simplifies this selector mechanism by using standard steel balls instead of specially designed plungers which substantially reduces the cost of manufacture.

Another object of the invention is to improve the layout of the machine from the standpoint of reading and operation.

Another object of the invention is to provide a voting machine which records each vote on a punch card for later computer counting and which also records every vote for each candidate on a mechanical counter which cannot be read until the machine is unlocked after the election.

Another object of the invention is to provide means whereby a stated number of candidates can be selected from a larger list, for example, as in a city council election, where there are to be only three candidates elected out of a slate of ten.

These and other objects will become apparent from the following description and the accompanying drawing, in which:

Referring now to FIGS. 1 and 2, when fully assembled, the voting machine consists of several identical columnar units included in a frame 10, and each columnar unit 11 comprising a body 12, voting keys 13, and a cover card 14 on which are taped or printed the various offices and the candidates names. A cover plate 15 along the left side of the machine conceals the card punching mechanism hereinafter numbered and described, leaving a slot 16 for the insertion of the card. Additional cover plates 17 along the top of the machine and 18 along the bottom serve to make the mechanism inaccessible to tamperers and to hold the machine together.

A voting lever 19 at the upper right hand corner of the machine is pulled towards the operator to register his vote. A re-setting key 20 is retained by an oflicial at the voting booth and used to release the mechanism after each vote is recorded, preparing the machine for the next voter.

The paired voting keys 21 along the top of the machine are for straight ticket voting as hereinafter described. The body 12 of each voting unit 11 contains apertures 22 through which mechanical counters, hereinafter described and numbered, can be read by removing the cover cards 14 when the machine is unlocked after the polls are closed. A key 23 fitting a standard tumbler lock (not shown) gives access to the inside of the machine and is retained by a qualified oflicial at election headquarters. The candidate-at-large selector mechanism index 24 is concealed by the lower cover plate 18 and must be adjusted at headquarters for each election when the machines are assembled, as hereinafter described.

Referring now to FIGS. 3 to 8, inclusive, the selector mechanism comprises, in multiple, the aforementioned voting key 13 shown complete in FIG. and having a vertical post 25 with a socket 26 at its lower end. A slide 27 extends horizontally from the post 25 and contains a hole 28 accurately machined so that the periphery on the far side is circular and the wall 29 of the hole opposite the post 25 is cylindrical and perpendicular to the plane of the slide 27. The wall 30 of the hole toward the post 25 is cylindrical at a 45 angle to the plane of the slide 27. The thickness of the slide 27 is one-half the thickness of the post 25 and a flange 31 equal to the other half of the thickness of the post 25 extends from the post 25 to the hole 28, ending coincident with the diagonal cylindrical surface 30. The diameter of the hole 28 where it is circular on the far face of the slide 27 is equal to the combined thickness of the slide 27 and the flange 31. A finger 32 having a cam surface 33 extends beyond the end of the slide 27 for the purpose of operating a mechanical counter as hereinafter described.

The body 12 of the voting mechanism comprises a pair of notched plates 34 and 35, respectively, and a series of identical pairs of interlocking blocks 36 and 37, respectively, which fit into the opposing notches of the plates 34 and 35. As detailed in FIGS. 6 and 7, the larger block 36 partly surrounds the smaller block 37 and is U-shaped with legs 38 which, in outline, match the outlines of the end faces 39 of the smaller blocks 37. Two horizontally separated and parallel holes 40 and 41 having their centers parallel to the length of the body 12 are located on the vertical center of the smaller blocks 37. The hole 40 extends through each block 37 while the hole 41 is blocked off near the surface 42 to form a socket. The diameters of the holes 40 and 41 fit the diameter of the hole 28 in the slide 27. The space between the legs 38 on the larger block 36 [37] is equal to the length of the smaller block 37 plus the distance between the centers of the holes 40 and 41.

The back of each larger block 36 is provided with a hole 43 of the same diameter and which will align with either of the holes 40 or 41 [41 or 42] when the smaller block 37 is resting against one or the other of the legs 38. The back of the larger block 36 is slotted horizontally to accept the flange 31 of the slide 27 of the key 13. The blocks 36 and 37 and the key slide 27, when nested, make an assembly three times as thick as the diameter of the hole 40, as is clearly shown in FIGS. 3 and 4. As shown in FIG. 8 the assemblies are stacked one adjacent the other in any convenient number by fitting the same into the matching notches of the plates 34 and 35. A blank 44, with the outer shape of the larger block 36, but without a hole or slot, is provided to end the series as shown in FIG. 8'.

When the aligning holes in the parts forming the body 12 are filled with identical steel balls 45, there is a pattern as disclosed in FIGS. 3 and 4. Each socket 41 in the smaller block 37 contains one ball 45a supported by a helical spring 46 which forces it against the larger block 36. The balls in the holes 40 in the smaller blocks 37 and the holes 28 in the slides 27 make a continuous column for all the candidates for one office. The candidates are separated by moving one of the smaller blocks 37 to the right where the hole 41 lines up with the hole 43 in the larger block 36. The head of a set screw 47 in the top of each smaller block 37 fits into either end of a dumbbell shaped slot 48 in the upper notched plate 34. The blocks 37 at positions A A and A in FIG. 3 have been set to start a column of candidates for a different ofiice. To accomplish this the set screw 47 is loosened to where it can be moved in the slot 48 then the key 25A in that block assembly is pushed to the left like the key 25B (shown for convenience just above) forcing the whole series of balls 45 downward so that the ball is eliminated from the hole in the slide 27 of the key involved. Then the block 37 is moved to the right and secured by the set screw 47. When the key 25A is returned to its right hand position the ball 45a centers the hole 28 in the slide 27, as shown at position A. Key 25B, as shown, should be considered only as an illustration of what happens when key 25A is pushed to the left to set the block 37. If it had been voted, the balls would be in a position indicated at A For the purpose of this description consider that the candidate above A has not been voted. No candidate in A A has been voted and one candidate in A A has been voted. When any key in a series is pushed to the left the ball 45 in the hole 28 in the slide 27 forces the column of balls downward, the last one 45a entering the socket 41 of the block 37 set at the bottom of the column. The spring 46, will not allow the ball 45a to drop more than one diameter into the socket 41, so it is impossible for more than one ball to be displaced, hence one key can be moved; and only one candidate can be voted in each series.

If it is desired to vote more than one candidate out of a series, as for example, a city council, the set-up illustrated in FIG. 4 is used. The blocks 37 are all in the right hand position so that there is a continuous column of balls free to move downward against a spring supported stop 49 slidably installed in a tubular receiver 50 the size of the balls 45. A U-shaped block 51 is attached to the stop 49 by means of a pin 52 and operates smoothly on guide rods 53. The compression spring 54 supporting the stop 49 is relatively long and limber allowing a substantial travel of the stop 49. Each time a key 13 is moved to the left (starting at the top of the column and working down) to vote a candidate, the column of balls 45 is moved downward displacing the stop 49 the diame ter of one ball. A shoulder 55 on the extension 52 will eventually come to rest against an indexing block 56 held by an adjusting screw 57 stabilized by a slide rod 58 and turned by a thumb screw wheel 59. When the machine is set up for voting the indexing block is set for a certain number of allowed selections out of the list of candidates on that column, as shown in the cutaway portion at the bottom of FIG. 1. In FIG. 4 three candidates in the series have been voted and there is room for two more. The parts described above belong to the candidate-at-large selector mechanism 24 mentioned early in the description and further described below.

It might be that there are more candidates-at-large then can be listed on one column, or that more can be voted out of that list than can be accommodated by the receiver 50. Thus it becomes necessary to list the candidates in two or more adjoining columns that are mechanically interacting. Referring now to FIGS. 8, 10/! [8A,] 9, and 10, it will be seen that the bottom of the U- shaped lock 51 carries a sheave 60 around which runs a chain 61 which is threaded over paired sheaves 62 attached to the body 12. This configuration is repeated on each column and the ends of the chain are fixed (by means not shown) so that if the U-block 51 on any one column is pushed back one ball diameter, taking up the chain, it limits the available travel space of the U-block 51 on the adjoining column by one ball diameter. For example, if there are eight candidates to be voted out of a slate of thirty and the receiver will accept only six balls, then twenty candidates can be listed on one column and ten on the adjoining column. If all eight candidates voted should be in one column, two of them would have to be transferred automatically to the receiver of the other column as above described.

The last referred to action is shown diagrammatically in FIG. 10A [8A] in which one end of the chain 61 is fixed at the point 60 [63] on the first body 12 and the other end of the chain is held taut by a spring 64 but is prevented by an adjustable stop 65 from extending to include more than the allowed number of elected candidates. Thus, if out of eight candidates five are voted out of column II, only three more can be voted out of column I, as shown by solid lines. But if only three are voted out of column II, as shown by the dotted lines, then five can be voted out of column I.

The straight ticket voting mechanism, detailed in FIGS. 15, 16, 17 and 18, consists of an elongate bottom plate 66 attached directly under all but the last two bodies 12 as shown in FIG. 16. Two parallel bars 67 are integral with the elongate plate 66, and two slightly smaller bars 68 lie alongside of the bars 67 and are attached thereto by toggles 69. The bars 68 are linked to the straight ticket keys 21 as shown in FIG. 17 and are held in the down position illustrated by springs 68a. The ba s 67 and 68 are supplied with holes 70 and 71, respectively, one each for every voting unit in the body 12 and which are designed to receive pins 72 and 73, respectively, on cams 74 which can be lifted out and placed in any parr of holes corresponding to any voting unit. A cam IS placed on one pair of bars 67 and 68 under each Democratic candidate listed on the column and on the other pair of bars 67 and 68 under each Republican candidate listed on the column. When the Republican key 21 is forced upward, all the cams 74 on that pair of bars will swing to the position shown dotted in FIG. 15, voting all the Republican candidates in that column as further explained below. Since one Republican candidate in each series has now been voted, it is impossible to move the Democratic key 21, as this would tend to cause an additional voting key 13 to move in each series, which would be impossible.

The cams 74 in the straight ticket voting mechanism interact with a series of transverse slide bars 75 which are notched where they intersect the key posts 25, each notch 76 being of sufficient length to allow the key post 25 to travel the full length of the voting stroke without displacing the slide bar 75. Depending pins 77 on the slide bars 75 are the means whereby the cams 74 move the slide bars 75 and each slide bar, when moved by its corresponding cam 74, in turn moves its corresponding voting key 13 by hearing against the key post 25. In the machine herein illustrated the last column is devoted to constitutional amendments or other propositions requiring yes or no vote, so the notches 76a for this column on the slide bars 75 are long enough so that the keys in this column are not affected by the cam action in a straight party vote.

A re-setting unit comprises two stationary anchors 78 for a pair of toggles 79 which extend to a rigid bar 80 which lies just under and perpendicular to the slide bars 75, and which, when forced to follow the swinging are 81 of the toggles 79, will bear against the depending pins 82 forcing all the slide bars 75 back to their original positions and re-setting all the voting keys 13 by means of the notches 76 and the key posts 25. In FIG. the slide bar 75a only is shown in the extreme right hand position required to reset the key posts 25. Light tension springs 75b anchored to the frame 10 attached to all the slide bars, but shown only once, return the bars to the ready position described above. The reset bar 80 is powered by a pressure block 83 (FIGS. 15, and 21) which is moved in turn by a pawl 84 engaging a hook 85 on the pressure block 83. The pawl 84 is actuated by the return spring 86 of the voting lever 19 as hereinafter described, so that every time the lever 19 is pulled and released the vote is registered and the machine is cleared. A roller 87 attached to one end of the reset bar 80 coacts with a cam face 88 on the pressure block 83 to transmit the required motion to the reset bar 80, and the block 83 is guided by slide rods 89.

After each voting operation an ofiicial inserts the reset key 20 between rollers 90 on the pressure blocks 83 and 91 on the pawl 84 forcing the latter off the hook 85, allowing the reset bar 80 to be returned to its original position by means of a spring 92, connecting the bar to the frame 10. For each voter a punch card is inserted in the slot 16 at the upper left hand corner of the machine. The card punching unit is primarily illustrated in FIGS. 11 to 15, inclusive, and comprises a bank of selector plates 93, one for each voting columnar unit 11. The plates 93 are grooved longitudinally, parallel to the voting colums 12 to receive push rods 94, each progressively longer by the space required by one voting unit body 12. The longitudinal grooves 95 extend the full length of the plates 93 and are intersected by transverse grooves 96 opposite the voting unit bodies 12, each reaching progressively from just beyond the first groove 95 to just beyond the last one.

Transverse push rods 97 are attached to the sockets 26 at the lower ends of the voting key posts 25, the rod at the top of the column being the longest, and each one being shorter in a descending series so that it will block the movement of its corresponding longitudinal rod 94 when the key is voted, but will allow the rod to pass when the key is not voted. The key posts 25 are progressively longer for each voting column to align the transverse rods 97 with the respective selector plates 93.

The longitudinal push rods 94 extend through a movable perforated plate 98 at the end adjacent the card slot 16 and are locked on the far side with snap washers 99. Close to the movable plate 98 there is a matching stationary perforated plate 100 holding punches 101 axially aligned with the punch rods 94 and held in place with snap washers 102. A punch plate 103 and a guide plate 104 are held together on each side of the card slot 16 by pins 105. The movable perforated plate 98 and the guide plate 104 comprise a unit held together by side frame members 106. When the voting lever 19 is pulled towards the operator, bellcranks 107 on a jack shaft 108 (operated by a linkage described below) pull the punch plate 103 against the punches 101 by means of links 109. Only the punches 101 blocked by the push rods 94 which are in turn blocked by the transverse rods 97 attached to keys which have been voted will resist the motion of the punch plate 103 and perforate the card. The remaining punches 101 will slide through the stationary plate 10, displacing their respective push rods 94. When the lever 19 is released, the punch plate 104 returns to its original position, stripping the card off the punches 101, and the perforated plate 98 pulls the rods 94 back to their original position by means of the snap washers 99.

The jack shaft 108 (as shown in FIG. 20) is actuated by a bellcrank 110 connected by a link 111 to a lever 112 actuated in turn by a bellcrank 113 on the main shaft 114 to which is attached the voting lever 19. The length of the lever 112 and the shortness of the bellcrank 113 adds considerable mechanical advantage where it is required to punch the card if a large number of keys have been voted.

The card is printed with a space for each possible write-in candidate, and the voter writes the name on the card and then votes the corresponding write-in key on the machine, which will punch the card to show that a write-in vote has been cast for that office. Referring again to FIG. 20, the pivot pin 115 which connects the bellcrank 113 to the lever 112 carries a sheave 116 around which runs a chain 117, one end of which is attached to the frame of the machine and the other end of which is attached to the sliding block 118 which carries the above mentioned pawl 84 which engages the pressure block 83. Tension on the chain 117 is maintained by a spring 119. This chain and pulley linkage provides for the relatively long travel of the pressure block 83 required to reset the machine. The pivot pin 115 also operates a link 120 running to a bellcrank 121 which turns a second jack shaft 122 which has attached thereto a short bellcrank 123 for each column 11 of voting units in the machine. Pins on the bellcrank 123 operates slidably in goosenecks 124 on the ends of slide rods 125 extending through each voting column, giving said rods a reciprocating motion.

Referring now to FIGS. 19 and 3, a three digit mechanical counter 126 operated by a star wheel 127 is mounted along each voting unit in the column 12. Mounted along the slide rods 125 is a series of pawls 128, one for each counter. When a particular candidate is voted the cam surface 33 on the finger 32 of the key slide 27 moves under the pawl 128. Then when the voting lever 119 is pulled the pawl 128 rides up over the cam surface 33 and engages the star wheel 127 of the counter 126, registering one vote on that counter. Since, at the beginning of the return stroke of the lever 19, all the voting keys are cleared far enough for the cam surface 33 to miss the pawl 128, it does not engage the star wheel 127 on its return trip.

The last voting column 11 adjacent the punch card bank 94 is purposely used for questions involving only certain precincts, and the keys not to be voted in any one precinct can be blocked by means of pins 129, FIG. 16, set in a shaft 130 lying just under and parallel to the body 12. The sequence of the pins can be arranged to lock out certain keys in each precinct, or, as in some elections, when only registered tax payers are to vote on a proposition, the election oflicial can turn the shaft 130 to block off the keys 25 as shown by the dotted outline of the pins 129 on ascertaining if the voter is eligible. The shaft 130 can be turned by the same key 23 that unlocks the voting machine, or by a special key, not shown.

Although the interacting mechanical motions of this invention may appear somewhat complicated, the end result is a greatly simplified voting machine from the standpoint of setting up for election, counting votes and use by the voter. A substantial reduction in cost and weight has been accomplished in relation to voting machines now in use, and the weight reduction alone is an important factor in the cost of elections as the machines have to be transported from official headquarters to the polling places and back again for each election. Reduced cost of storage is also important, this machine having but a fraction of the volume of machines now in use.

The invention is not limited to the exemplary construction herein shown and described, but may be made in various ways within the scope of the appended claims.
