VOTING-MACHINE Specification of Letters Patent. l PtenfedNov, 30, 1909,

Application filed l.Tune 8, 1899. Serial No. 719,758.

To all whom it may concern.'

Be it known that I, JOHN HOWARD MC- ELROY, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Voting-Machines, of which the following is a specification.

My invention is concerned with certain new and useful improvements in the interlocking mechanism of voting machines, which is the mechanism associated with the individual candidate registering or counting mechanisms toprevent the voter from casting, more candidates than there are offices to be lilled, and my invention is concerned with a lsimple mechanism of the class described,

which is available not'only for single-candi date to be elected groups but more especially for multicandidate to be elected groups.

Referring to the drawings, in which the Same letters of reference are used to designate identical parts in all the figures, Figure 1v is a' plan 4vlew withthe cover removed, and with the lower portion of the machine in sectionon the line 1-1 of Fig. 2; Fig. 2

Y is a vertical section throu h the machine on the line 2-'2 of Fig. 41; i 3 is a vertical section on the line 3-3 o Fig. l; Fig. 4 is a fragmentary plan view on the line 4-4 of Fig. 2; Figs. 5, 6 and .7 are a plan view, side elevation, -and end elevation, respec* tively, of the ballots holder; Fig. 8 is a tion of the same on the line 8-8 of Fig. 5; `igs. 9, 10 and 1l are a side elevation, perspective, and longitudinal section, respectively, of the holder employed for use `in connection with the irregular balloting mechanism.

My present voting machine takes the general form, of a ballot box, and is of the type of machines where actual tokens or ballots are employed to register each vote cast for each candidate. The box consists of the bottom piece A, the end ieces B, the side'pieces C, and 4thelid D, w ich may be hinged to the rear sidel iece C so as to be turned up when the mac ine is in use, or it may be entirely removed during the election. The ballots or tokens E I preferably make in theformof disks, which in-size and' shape may be similar toone of the 'smaller coins, such as a penny, or the nickel five-cent piece.

or attempting to cast, his ballot fo'rl If desired, the ballots foreach o'iice may be separately marked, but this is an unnecessary refnement. These tokens or ballots E are deposited inl the ballot holders F, which are a series of elongated metallic tubes, the tubes for each party being conveniently 'arranged upon a single slide G, which rests upon the bottom piece A, and when the returns of the election are to be canvassed, the door H in one of the sides C is unlocked and swun down about the hinges J so that the slides can be withdrawn one at a time and the ballots therein for each individual candidate counted. To facilitate` the counting of these ballots without stopping to handle each one, I form the two staggeredy rows of perforations K in the outer side of the tubes, and between these perforations I form a scale, and the perforations overlap sufficiently so that the, height ofthe disks in each tube can'be readily seen, and by comparing the height with` the scale, the number o f ballots in each tube, and the consequent number of votes cast for that particular candidate with that machine can be readily and speedily ascertained. lThese tubes are conveniently formed of sheet metal, and may be slipped overor secured to the circular blocks L which are screwed down to the slides G, as

shown in Fi 2. While the tokens before being actual y deposited in the tubes are placed in a straight line,`as indicated by the position of the apertures T in Fig. l, for economy of space, I preferably arrange these tubes F in a staggered row, as best shown in Fig.' l. To assist in directing the tokens into their respective tubes, I may form the flanges M projecting from the top of each of the tubes, as shown in Figs. l and 2.

l/Vhile I have shown the box as comparatively shallow, and the tubes as capable of accommodating only` comparatively a small number of bal ots, it will be understood 4that in practice the tubes will be three or four feet long, so as to be able to accommodate as high as five hundred tokens in each tube, ywhich is the maximum number that would ever be cast for any one candidate, as the machines are designed to accomnlodatc about .six hundred voters in a precinct, and one machine should be employed in each precinct. l

The controlling mechanism for the ballots or tokens consists of a movable plate .N

SO l slot for each candidate and tube F, and these which is substantially the width of the inmit the ready passage of a token through lthem and into the tubes F. In its normal position, however, the apertures Q are so placed as to be out of register with the tokens placed in the machine, so as to prevent their falling into the tubes.

A short distance above the plate N, preferably slightly less than the radius of one of the tokens, is Xed a plate R-, which is preferably metallic, and covers the ent-ire interior of the machine, it being conveniently secured in place by being made wider and longer than the inside of the machine, and taking into grooves S formed in the sides and ends of the vertical Walls of the machine. This plate R is formed with a series -of slots T therein,` which, as previously stated, are formed inl straight lines representing the parties, and there is one slots are slightly longer than the diameter of the token, and slightly Wider than its thickness, and bear the relation to the apertures Q in the plate N so that when the tokens are placed in. thefslots T they vwill be held substantially vertical, and will rest i on the plate N between the apertures Q.

-On the plate R are located a number of controlling blocks U, which are secured in Y channels ormed on the plate R by longitudinal stri s V which are conveniently bolted or rivete to the upper side of the plate R, but which might be formed integral therewith if desired. These blocks U are of the shape shown in Figs. 1, 2 and 3, and consist ofelongated rectangular blocks having the upper portions of their sides and ends' beveled ot, say at an langle of sixty degrees. To conveniently secure these blocks in their channels, and to prevent their removal, the strips V have secured on their upper sides the strips W, which I preferably form of glass, so that a printed paper strip containing the name of the candidate and the oice for which he is running may be placed between the upfper side ofthe strip V and the under side o the strip W, and thusbe visible to the person usin the machine. These strips W have their si es beveled at an angle corresponding to that at which the sides of the blocks U. are beveled, so that the strips W overhan the blocks U and prevent their being lifte up. The strips-V Aand lV are 'also continued at the sides and ends of the h of the inside of the mad This plate is supported upon same ofi machine, so as to form the ends of 'thechannels, and these ends are likewise beveled so as to prevent the Withdrawal of the blocks. In each of these channels is placed a number-of blocks referably corresponding to the number o? political parties,l and the channel is enough longer than the 'combined lengths of the blocks so as to make it possible to completelyA uncover oneand only one, of the slots T in each channel, so that only one token can be placed in a channel at a time. Of course, it will be understood that each channel is devoted to the candidates of the different political parties for the The general operation of the device will now be readily apparent, as if a token is placed in position for one candidate for each oice to be filled, and the voter can put only one token in place, and after'the voter has left the machine, the plate -N is pulled to the left b means of the handle X which is attache to an extension Y of the plate N, which extension passes through an aperture Z in the vend or the machine, the tokens placed in the slots T, which are supportedbyl the plate N While the voter was at the machine .are permitted to fall through the apertures Q and into: the tubes F, as the movement of the plate N by the judge of the election, or automatically as the voter leaves the booth, serves to bring the apertures Q beneath the slots T.

To provide for the rapid placing of the tokens in the slots T if a straight ticket, or a substantially straight ticket, is to be voted, I provide the following mechanism: To get all of the slots T accessible for the. particu@ lar party for which the voter desires to cast a substantially straight ballot, Iv place two rods A 'across the machine near to the sides and these rods may be secured in place by a bolt head and a nut on the outside of the box, as shown. Upon these rods slides an adjusting mechanism B which may conveniently be constructed of the two tubes G sliding on the rods A, and conducted by the rigid rod D which may be conveniently screw-threaded into offsets in the tubes C, and by the rod E which is pivotally mounted at its ends to the tubes C and extends parallel to the rigid rod D. This rod or rock-shaft E is provided with a number of arms F,

the inner ends of which are shaped so as to engage with the ends of the blocks U which project above the surface formed by the strips W. 1

The operation of this device will be readily` apparent. Assuming that it is in the position shown .in Fig. l, if the voter desires to vote the straight ticket for the party occupying the irstcolumn, he will shove the device B to the right the length of one block U, when, of course, all the blocks will be carried from over the column in which he desires to place the tokens.

Should he desire to cast a vote for the party occupying the thirdcolumn, instead of stopping the operation at this point, he will then turn the rock-shaft E upward and over an angle of about 240, when the arms F will be ointed in the opposite direction, and rea y toengage the o posite ends of the blocks. The device B 1s then slid until the arms F engage the ends of the blocks U which are over the column he desires to vote for, and the; device B is then shoved to the left for the length of one block U, thus uncovering the apertures T of the party for which he desires to vote. To further assist the rapid placing of the tokens E, I referabiy provide a carrier G', shown in Figs. 5

to 8, the object of which is to hold 'the complete set of tokens for all the offices to be filled in position so thatthey can be instantly dropped into the slots T. A plurality of the carriers G is provided, and the tokens are inthe hands of some election oliicials, who keep the carriers filled with the necessary tokens, so that a voter before entering the booth in which thc machine is placed is provided with a carrier containing all the necessary tokens. -Afterthe blocks U have been manipulated by means of the device B, as previously set out, the carrier G is placed in the appropriate pair of the recesses H which areformed in the parts J which are secured Aabove the continuation of the strips W and next to the side walls C. The width of `these notches H is ust suilicient to accommodate the ends of the carrier, which are placed across the machine so as to place the lower end of eachtoken just above the slots T. The carrier is then Anianipulated so as to drop the tokens into the slots T, and the carrier is then removed. If any candidate is to be scratched, the token in his slot is lifted out, and the slide U covering the slot fortlie candidate for whomit is desired to vote is moved so as to cover the slot from whichrthe token wastaken and to uncover the slot in `which the token is to`bej laced. After the tokens have all been ad- ]usted, the Work of the voter is completed, and he can leave the booth.

The specific details of the construction ofA the carrier G will now be described. It is in the form of a clamp, consisting or" the aw K which may be composed of a comparatively thin sheet of metal; having a handle L formed there by extending a. portion of the sheet K upward and turning over the edges of the upwardly projecting portion, as shown at M.v The ends of the clamping member K are preferably turned at right angles to form the ends N, which, of course,

are a width to fit into the notches or reso as to turn up the lower portion O thereof at right angles, so as to furnish a little greater bearing supportl for the carrier. The other clamping member may consist of a tubular body portion P which is secured in position by the rod or bolt Q passing therethrough and through apertures i`n the ends N, outside of which said rod is headed or riveted so as to secure it in position. The body portion P is provided with a handle R opposite the handle L of the other clamping member, and an expanding coiled spring S is secured between these handles and tends to keep them apart. The jaws T of this member are of the shape best shown in Fig. 8, where it will be seen that they are formed integral with the tubular body porvtion P, and are of a shape to clamp the token against the opposing plate, which might also be slotted i desired. The inner sides of thejaws T are provided with the grooves U which are of a width and depth to securelyhold the token in the position shown in Fig. 8. lVhen the carrier is placed in the depositing position, each of the tokens E will be above a slot T, and when the handles M and R are brought together by the movement of the handle R against the resistanceof thespring S, the tokens will be releasedand'will :tall into the slots T, as previously"e 'plained InA soine States, there are different classes of voters, depending upon the amount of suffragev that is extended to them. For instance, in the State of Illinois, the women of legal age are permitted to vote for all the educational oilicials, and in the State elections, they have the privilege of voting for the three trustees of the State University which are elected at the time of the congressional elections. This necessitates making some provision whereby Voters of a limited franchise can be provided for, and in the present machine l havel illustrated a construction i'n which the three ballots for the trustees of the State University can be cast by a voter having that limited franchise without the possibility of casting any for some other oifice to which they are not entitled to vote. This I accomplish by dividing the plate N into two parts, and so connecting these parts that when a voter having a full franchise has deposited his ballot, the

entire plate N` will be moved, depositing in the machine all the tokens which can be placed therein. When a voter having a limited franchise votes, only the portion of the plate N pertaining to the receptacles Ior that oiicegand which portion I have lettered V', will be moved, and, consequently, if the tokens are placed elsewhere than in the slots in which they'should be placed, they will not be cast when the voter leaves the machine. Referring especiallyto Fig. 4, where I have shown the plate V as in its operated position, it will be seen that it is piush with the plate N, which is, on account of the position ofithis plate V, virtually separated into two parts, which, however, are connected by two or more cross pieces J shown only in Fig. 2, and connect the two pa-rts of the plate N passingfbeneath the plate V. The plate V has the general shape shown in Fig. 4, and is provided .with van extension W and a handle X similar to the main handle X of the plate N. The 'rear portion of this plate V has twovott'set portions as at Y', forming shoulders that cooperate with the complementary shoulders Z on the plate N, so that when the plate N is drawn forward, the shoulders Z cooperating with the shoulders Y will also carry the plate V forward, but when the plate V is carried forward,

it does not move the plate N. Thus, 'it will' be seen t-hat if the voter ot' limited franchise should place the three tokens furnished in the slots for some oiiicials of more impor.- tance, t-he election otlicials by moving` only the handle X would not permit any 1mproperly placed tokens to be cast into the machine-.

As is well known, groups of oiticials are sometimes elected, and such groups are known as multi-candidate groups. As they are ordinarily voted for, each party nomi-l nates one candidate for each place, and as in the case of the trustees for the State University, just considered, each party nominates three candidates, but the voter is at liberty to cast one of his votes for t-he candidate oi the Republican party, another for a candidate of the Democratic party, and perhaps a third for a candidate of the Prohibition party. In such case, it might occur that the apertures T in which he desired to place the ballots are all in the' same longitudinal channel, so that if the ordinary construction were employed for these grouped candidates, it would be'impossible for the voter to cast his ballot for the candidates desired, because he could not open the three slots in the same channel. To overcome this diiiiculty, `in multi-candidate groups, I provide connections between the three channels at one or both ends, so that it is possible to get one channel completely filled with the blocks Il, while another channel has the customary number of blocks in it, while the third channel has one less than the customary number of blocks in it, so that one token' blocks in each group as the ballot counting mechanisms that can be actuated in t-he group by a single voter.

As shown at the right hand side of the machine, there is space for a set of blocks beneath which there are no holders. These blocks are used principally for refsetting purposes, as will be subsequently explained. The strips V and W extend between the blocks ot this extreme right hand end portion, as shown in the upper partI of Fig. 1,`

except between the three blocks oit the multicandidate group, where the strips V and W are cut out and their place is -taken by two extra blocks. At the opposite or lett hand end of the machine, I may form a similar space, as shown at A2, and fill it with tive blocks U, three ot which correspond to the positions of the blocks in the channel, and two of which serve as fillers to take up the space. In the complete system, there are blocks enough to till up the complete channel space and the end -space A2, except for three blocks, It will be seen that these blocks cannot be lifted out of position on account of the overhanging portions of thc strips IV or their continuations overhanging the beveled port-ions of the blocks. It will also be seen that by means of shitting t-hesc blocks across the ends, as may be necessary, any three slots T in the entire multi-candidate group can be uncovered. IVhen it is desired to vote for two or more candidates in the same row of a multicandidate group, some of the interlocking blocks N in the con necting end of the channel must be moved into the row or rows in which no candidates are to be voted for. The space in the connecting channel thus secured is illed by moving in the blocks from the row or rows in which more than one candidate is to be voted for. By a little manipulation, it will be apparent that any necessary arrangement ot blocks within the capacity of the machine can readily be made.

It is desirable to re-set the machine after each person has voted so that the next i'oter entering the booth cannot by an inspection ot' the blocks see how the last voter has east his ballot. It is primarily for this purpose that the right hand end row of blocks U is provided. Just bciieath this row of blocks is a series of slots B2, which are about halt the width ot' the block, and exactly of the length of a block. The plate N has rigidly fastened therein and projecting upwardly therefrom the teeth C2, which are of the shape shown in Fig. 2. These teeth C2 project upwardly through the slots B2 and when the plate N is in its normal position are directly behind the right. hand end blocks U. As the plate N is moved to cast the ballots, these teeth C2 taking against the` ends of the blocks U at the right hand end of the machine will move them and, consequently, those to the left of them, one space to the left, so that the voter enterm the machine will find all of the blocks Il at the left hand side of the machine, and all thefsiots T covered so that he cannot tell how thevdter immediately preceding him has voted. In connection with the multi-candidate group, a` slight modication of this structure is necessary, as it may sometimes occur, when a person is voting ascratched ticket, that he may cast ballots fortwo men in thel same horizontal row, in which case one ofthe other horizontal rows would be filled with machinerwas re-set, it would be impossible to move the block U at the right hand end to the. left in resetting, inasmuch as the channel is entirely filled.V Consequently, it becomes necessary in connection with this multi-candidate-group to have the teeth C2v arranged with yielding connections, so that if any channel is full, the machine will not be brokenin an endeavor to re-setit. For this purpose, I place the teeth G2 of the multi-candidate group in special slides D2, which slides are placed in channels E2 formed-in the plate V', or they will be in the plate N if the multi-candidate group did `not at the same time belong to the limited franchise'group, as in the present case. The slide D2 has secured to its upper side a cross ieee F2, to which are secured two long elically coiled springs G2 which are also secured to the plateV piece H2 passing through the. teeth C2 of the multi-candidate group v beneath the slots J 2 in the ri ht hand supporting plate O serves to hold -t e plates D2in position against any possible'tendency of the spring to 'tilt them or otherwise disarrange them. When the channel ofl any of the multi-candidate groups is filled with blocks, and the plate V is moved forward either directly or by means i N, the plate ofthe movement of the plate D2 of that particular channel remains stationary, as illustratedin the central one in Fig. 4, and the expansion of the springs G2 permits this. The strength of the springs G2 is sufficient to overcome the slidin resistance of the blocks, and thus re-set t em, if the blocks are 'so .positioned as to leave a vacant space-in the channels.

The rlght hand set of 'tubes and slots isl provided for irregular balloting, and this I preferably accomplish by having the token.

1n the form of a holder, such as shown in Figs. 9 to 11, into which a piece of paper having the` name ofJ the. candidate' written thereon can be inserted, and the holder inserted in .the machine just the same as a token'. I preferably make the apertures T for the irregular balloting of twice the width of the ordinary apertures, so as toenable me to make the holder` of greater thickness. These holders may be of any desired form, but I preferably make them of the shape blocks so that as the.

A pin or'other cross shown in Fig. 9, where it will be seen that the lower half of the holder K2 is dishshaped, while the upper half is mostly cut away, except a tongue L2,4 which presses down into the central ortion of the holder and serves to hold the olded ballot which is placed therein securely in the holder and. preventits being displaced. Of course, I might make these holders somewhat like a pill.d box, and of two separate parts, but the structure shown consisting of a single metallic sheet metal piece is preferable as there is no possibility of the parts becoming separated.

,While I have shown the various features 0 of my -invention as applied to a token receiving voting machine, it will be apparent that some features thereof might be applied to the more common type of machines in which wheel registers operated 'or controlled g5 by candidate'keys are employed. For instance, it -will be apparent that the interlocking block system for the multi-candidate groups might be applied to the keys for such a wheel register instead of to the tokens. Similarly the method of controlling the limited franchise voters by only arranging the machine to operate such ballot candidate mechanisms as their franchise entitles them to operate might. also be applied to a wheel register voting machine. Consequently, when I employ the term register mechanisms or ballot counting mechanisms etc., I do not desire to be understood as limiting myself to any one form of mechanism.

While I have shown my invention as embodied in a form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of modifications, and that I do not desire to be limited in the interpretation of the following claims by the language thereof, but only as may be necessitated by the state of the prior art. g

While I have .shown and described the 11o general mechanism connected with the above mentioned machine, irrespective of the interlocking mechanism employed, I do not herein claim the same, the present applicationbeing limited to the inter but reserve the subject-matter of the same for'a divisional application.

Havingnow described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is:
