' VOTING MACHINE Filed Oct. 17, 1962 2 Sheets-Sheet 1 2o' '4 l 24 RICHARD rswANsoN l0 March 23, 1965 R, T. swANsoN VOTING MACHINE 2 Sheets-Sheet 2 Filed oc'. 17. 1962 \\\gl e INVENTOR RICHARD T SWANSON United States Patent O 3,174,685 VTING MACHINE Richard T. Swanson, Jamestown, NY., assigner, by

mesne assignments, to Automatic Voting Machine Corporation, Jamestown, N.Y., a corporation of Delaware Filed Get. 17, i962, Ser. No. 23l,l73 l Ciaims. (Cl. 23S-54) This invention relates to voting machines, and more particularly to improved vote selection and cancellation means, to be actuated by the voter.

One object of the invention is to provide an improved presentation oi the voting facility.

Another object is to provide in a machine as aforesaid an improved push-button type vote selection device.

Another object is to provide in a device as aforesaid an improved switch arrangement employing means for converting lineally directed push or pull button movements into rotary output motions.

Other objects and advantages of the invention will appear from the specification and the accompanying drawings wherein:

FiG. l is a fragmentary front elevational view of a voting machine face embodying a group oi vote selection and cancellation devices of the invention;

FiG. 2 is a plan view on enlarged scale of one of the devices of FIG. l; taken for example along line 2-2 of FiG. l and showing the vote selection member in actuating position and the vote cancellation member in its normal or inactive position;

FIG. 3 corresponds to Fl'G. 2 but shows the vote selection member in inactive position and the vote cancellation member in actuating position;

FlG. 4 is an enlarged scale sectional view taken on line 4 4 of FlG. 3;

FG. 5 is a fragmentary section taken on line 5-5 of FlG. 4; and

FIG. 6 is a sectional view taken on line 6 6 of FIG. 4.

As shown herein the mechanism of the invention is adapted to be fabricated into the form of a self-contained module such as indicated generally at id, pluralities of which may be slip-iitted into appropriate cavities in the face of a voting machine as indicated at l2, whereby the modules are arranged in vertical columns and hori- Zontai rows. Each module includes a base plate le bolted to an insulation plate and having an upturned iront framing panel lo terminating in a reverse bent top ilange i8 for stitlfening purposes. The front panel 16 is apertured to accommodate in free sliding relation therethrough a vote selection bar 2h and a vote cancellation button 22. These members are carried by separate, movable frame devices so as to be reciprocable in and out of the apertures of the front panel. ln turn, lineal motions of the frames are transmitted to devices converting these motions into rotary motions, as will now be explained in detail.

in the case ot the vote selection bar 2t), because of its lateral elongation it is preferably formed with a pair of pivot posts 2d, 24 adjacent its opposite ends, and each post is pivotally connected as at 26 to one end of a scissors link 28 which is pivotally mounted at 3h upon the base plate la. The links are centrally interconnected at 32 by a pivot pin whereby motion of the bar 2t) will be at all times in squared relation to the front panel. A strut device 34 extends from the bar 20 and rearwardly therefrom to receive in journalled relation at 36 the stub shaft end of a thrust bar 3E. The thrust bar 38 is of polygonal sectional form and extends into a bore 39 formed within a bearing block All) which is contra-bored as indicated at ftrom its opposite end to provide an ICC internal shoulder 42. The thrust bar 38 is formed with an enlarged shoulder 44 against which a compression spring do is seated. A guide plate 48 is xed to the rear end of the block d0 as by means of screws 49, and maintains the spring 46 under compression. Thus the spring constantly biases the thrust bar, strut, and selection bar assembly toward'the left as viewed in FIG. 4, or to normal or inactive position.

in the region of the guide plate 48 the thrust bar is twisted as indicated at Sti and the aperture through the guide plate 48 is shaped to complement the sectional form of the thrust bar portion 5@ while accommodating it in free sliding relation therethrough. As indicated at 52, the outer end oi the bar portion 5@ carries the output member which is to transmit the voters action to the mechanism for entering his selection. For example, as shown in FIGS. 2, 3 the member SZ carries a mercury switch 5diso as to rotate it alternately between open and closed switch contact positions. Thus, voter depression of the bar 2@ against the action of the spring 46 will cause the switch to either open or close, according to the switch arrangement, for appropriate control of the associated circuit for entering the voters selection into the voting machine. Whereas in the drawing herewith the thrust bar is of rectangular sectional form, it will be appreciated that it may be of any other suitable keyshaped sectional form, and may be machined or cast or otherwise fabricated to provide the twisted conguration.

As stated above, when a cauce button is provided as at 22, a similar actuating mechanism may be employed to include a strut arrangement 5o connecting to a similar thrust bar and spring and guide plate arrangement, as in connection with the selection bar 2t?. The output member again may be of any preferred form, such as another mercury switch, or the like, to control a mechanism for cancelling the previously made selection.

To prevent simultaneous actuation of both the selection bar Ztl and the cancel button 22, an interlock plate as shown at 6l) is provided to slide within a slot 62 formed in the bearing block et?. The push bars 38, 3S are necked down as shown at 64, 64 in the region of the interlock; plate and the latter is dimensioned to tit between one of the necked portions while resting against a full size rounded portion of the other bar. The bars are bevelled as shown at 66, @o to facilitate shiitiny of the interlock plate to accommodate depression of either one of the selection bar and cancel button members, while preventing simultaneous actuation thereof. indication lights may be provided as indicated at 70 and 72 behind the selection bar and the cancel button, respectively, to provide visual indication of the voters use of either device; energization of the lamps being controlled by any suitable associated circuitry.

`it will, of course, be appreciated that whereas only one specific form of the invention has been illustrated and described in detail hereinabove, various changes may be made without departing from the spirit of the invention or the scope of the following claims.
