BALLOT MARKER 5 Sheets-Sheet 5 Filed Nov. 2l, 1960 INVENTOR. 75e PETTEQS 0^/ BY Mum Afro/@MEV United rates Aircraft Corporation, East Hartford, Conn., a corporation of Delaware Filed Nov. 21, 1960, Ser. No. 70,827 8 Claims. (Cl. H11- 363) My invention relates to a ballot marker and, more particularly, to an improved device for causing a marking member to strike the surface being marked with a uniform force.

In many systems presently in use, such as for counting and sorting of ballots or the like, the ballots of a stack of marked .ballots are automatically scanned to count the lballots or to sort and count the ballots. Customarily, this is done by examining deposits of material placed on the ballots by voters. For example, a photoelectric system may be employed to detect marks and to determine their location on a ballot. In many systems, special inks such as are suited to the particular scanning system to be employed are used to mark the ballots. They may be particularly suited for a photoelectric scanning system or they may be magnetic or conductive inks.

In marking ballots, it is desirable that the deposit of the marking medium on all vballots be as uniform as is possible. Where the ballots are marked manually by the individuals of a large group, the chances that marks made with pencils or other known marking devices will be uniform are substantially nil. Thus, if such a marking means is employed, the scanning system may have to be sensitive to marks which diifer widely in size and in characteristic. The desirability of uniform marks will be apparent.

I have invented a ballot marker which is especially adapted for use to mark ballots which are to be handled by automatic tallying systems. My marker is so constructed that it always makes a mark of the same character, no matter how actuated. I provide my marker with means for insuring that the marking pad strikes the ballot, or the like, with a uniform force on each actuation. My ballot marker is simple in construction and inexpensive to manufacture for the result achieved thereby.

One object of my invention is to provide a ballot marker which is especially adapted for use in marking ballots which are to be counted or sorted on automatic tallying machinery.

Another object of my invention is toprovide a ballot marker which makes a uniform mark on each actuation thereof.

Another object of my invention is to provide a ballot marker which causes the marking pad to strike the ballot with a uniform force upon each manual operation thereof.

A further object of my invention is to provide a ballot marker which is simple in construction and inexpensive to manufacture.

A still lfurther object of my invention is to provide a manually-operable ballot marker which is rugged and reliable.

Other and further objects of my invention will appear from the following description.

In general, my invention contemplates the provision of a ballot marker including an inking pad which is normally telescoped within a sleeve carried by a handle. After the sleeve has been brought into engagement with the paper, and as the handle is moved downwardly against the action of a return spring, a separate printing spring is loaded. When the handle has been moved through a predetermined displacement, the marking pad holder is triggered to permit the printing spring which is uniformly loaded on each operation, to drive the pad into engagement with the paper with the same force on each operation. When the handle is released, the pad holder is returned to its initial position under the action of the return spring.

In the accompanying drawings which form part of the instant specification and which are to be read in conjunction therewith and which like reference numerals indicate like parts in the various views:

FIGURE 10 is a sectional view of my ballot marker taken along the line lil-10 of FIGURE 3 and drawn on an enlarged scale.

Referring now to FIGURES l to 3 of the drawings, my ballot marker, indicated generally by the reference character Ill, has a handle top 12 and a handle bottom 14 formed from any suitable material such, for example, as Bakelite or the like. The outer diameter of the top 12 is slightly greater than the inner diameter of a counter bore I6 formed in the upper end of the bottom 14 as viewed in FIGURES 1 to 3. When the top and bottom are to be assembled, the top is forced into the counter bore 16 and is rotated until locking lugs 18 formed on the outside of the top 12 ride into the complementary notches 20 formed in the counter bore 16. It will be appreciated that the material of which the top and bottom are formed is sufciently resilient to permit the top thus to be snapped into position. As can best be seen by reference to FIGURES 1 to 5, the handle bottom 14 slidably receives a sleeve 22 formed of the same material as are the top and the bottom. I provide the sleeve 22 with a pair of oppositely extending guide lugs 24 which ride in longitudinally extending grooves 26 formed within the bottom 14 to guide the sleeve in its movement with respect to the handle in a manner to be described hereinafter. As can be seen by reference to FIGURES 2, 4, 5 and 8 sleeve 22 is provided with a pair of pad holder guide slots 3ft and 32 having enlarged ends to form respective shoulders 34 and 36. We form the end of the sleeve remote from lugs 24 with a plurality of prongs 38 to facilitate the operation of holding the ballot marker against the paper to be marked in a manner to be described hereinafter.

Referring now to FIGURES 2, 3, and 6 to 9, the sleeve 22 is adapted to house a pad holder 40, one end of which is provided with a recess 42 which frictionally holds a pad 44 of porous material, such as sponge rubber, which is adapted to be saturated with a suitable marking fluid, such as ink.

I provide the pad holder 40 with a pair of oppositely extending cross-pins 46 and 48 which extend into recesses 50 and 52 formed in the inner surface of the bottom 14. I provide the inner surface of the top 12 with recesses 54 and 56 which are complementary to recesses 50 and 52. The bottom of each recess Sil and 52 forms a cam surface 58, while each recess 54 and 56 forms a cam surface 6l?. With the parts retracted in the position shown 3 in FIGURE 2 of the drawings, cross-pin 46 is held against the shoulder 36 of the guide slot 32 in the sleeve 22 by the cam surface 58.

The handle made up of the top 12 and the bottom 14 houses a return spring 62 which bears between a shoulder 64 formed in the top 12 and the upper end of the sleeve 22 normally to urge the sleeve downwardly, as viewed in FIGURES 1 to 3 to a position at which the lugs 24 are in engagement with the closed ends of the guide slots 26. In this position of the parts, a spring 66 bearing between the upper end of the handle top 12 and an annular shoulder 68 formed on the upper end of pad holder 40 normally urges the pad holder 40 downwardly as viewed in FIGURES 2 and 3 to a position at which the cross-pins 46 and 48 engage the shoulders 34 and 36 to which positions they are guided by the cam surfaces 58 of the recesses 50 and 52.

In operation of my ballot marker, I grasp the handle formed by top I2 and bottom 14 and press the prongs 38 against the paper to be marked. When a downward force is exerted on the handle, it moves downwardly, as viewed in FIGURES l to 3, in the course of which movement springs 62 and 66 are compressed. When the handle has been moved through a sucient distance that the cam surfaces 60 in the recesses 54 and l56 engage the pins 46 and 48, they cam the pins off the shoulders 34 and 36 as by moving the pin 46 to the right as viewed in FIG- URE 2. When the pins 46 and 48 are thus cammed off the shoulders, they are free to move downwardly as viewed in FIGURES 2 and 3, along the slots 30 and 32. ln this position of the parts, the compressed spring 66 drives the pad holder 40 downwardly as viewed in FIG- URES 2 and 3 to cause the pad 44 to strike the paper being marked to leave an impression thereon. It will be noted that, owing to the fact that no matter with what force the handle is moved downwardly after the sleeve is brought into engagement with the paper, the pad 44 strikes the paper in the same force, since print spring 66 always is loaded or cocked to the same extent by the travel of the handle with respect to the sleeve.

When the pressure on the handle is relieved and the handle moves upwardly, the sleeve 22 moves relatively out of telescoped relation to the handle while the pad holder remains stationary with respect to the handle. In use the sleeve remains in contact with the surface while the handle and the pad holder move upwardly. The pad holder is constrained to move upwardly with the handle by the engagement of cam surfaces S with pins 46 and 48. As the sleeve 22- completes this relative movement with respect to the handle, the slots 30 and 32 clear the pins 46 and 48 and the cam surfaces S8 move the pins 46 and 48 back onto the shoulders 34 and 36 thus to reset the device for its next operation.

It will be seen that I have accomplished the objects of my invention. I have provided a ballot marker which is especially adapted for the manual marking of ballots or the like which are to be handled by an automatic scanning or sorting machine. My ballot marker produces a mark of the same character upon each actuation thereof. I so arrange my ballot marker that the marking pad strikes the ballot with a uniform force each time the marker is actuated. My ballot marker is rugged and is reliable in use. My marker is simple in construction and inexpensive to manufacture.

It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of my claims. It is further obvious that various changes may be made in details within the scope of my claims without departing from the spirit of my invention.
