ELECTRICALLY-CONTBOLLED VOTINGMACHINE.

Specification of Letters Patent. Patented May 28, 1918.

Application filed October 2, 1916. Serial No. 123,271.

To all whom it may concern:

Be it known that I, BORNETT L. Bonnorr, a citlzen of the UnitedStates, and resident particularly hereinafter described and parof Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Electrically-Controlled Voting-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

The present invention relates to new and 1 useful improvements in electrically operated voting apparatus of the type embodied in my co-pending application for patent filed F ebruarylfi, 1915, Serial No. 8639, and including a plurality of main station mechanisms located at a desired central point, and a plurality of corresponding sub-station mechanisms located at the voters desks, for procuring selective diflering indicationsand actuations of the main station mechanisms, a single common photographing means being associated with the main station mechanlsms for photographing their indications to permanently register the individual votes, and a non-interfering total vote indicating means being associated with each set of corresponding indications of the main station mechanisms, and comprising a circuit having an ammeter therein and adapted to se1ectively include said corresponding portions of the main station mechamsms.

It is in general the object of the present invention to simplify and otherwise improve the structure and efliciency of the apparatus of my said previous application, and with respect to themain station indicating mechanisms it is more particularly an object to provide an arrangement whereby said mechanisms have selectively difieringwindications indicating circuits, whereby the operation of the totaling ammeters 1s exact.

With the'above and other objects and advantages in view, the invention resides more particularly in the novel combination,

arrangement and formation of parts more ticularly pointed out in the appended claims.

In the drawings Figure 1 is a plan view of one of the main station indicator mechanisms of my voting apparatus, embodying the present invention and with portions thereof broken away to more clearly disclose structure.

Fig/8 is a plan view of the visual indicatin plate.

Re erring now more particularly to the Figs. 1 to 6 of the accompanying drawings, the main station mechanism shown therein comprises preferably an aluminum base plate'5 mounted on a wooden or fiber support 6 and transversely journaled in upstanding bearing arms 7 on the plate 5 is a spindle 8 corresponding to the spindle of the main station indicatin mechanism of my said previous application, this spindle being urged to rotation in one direction by a splral spring 9 disposed thereabout and secured to the plate 5, and being normally held against actuation by the spring by a pawl 10 intermediately pivoted to one of the bearing arms 7 and engageable at one end with a ratchet wheel 11 on the spindle, and being extended at its other end to form an armature 12 .which is disposed over a pair of magnets 13 mounted on'the bed plate, ex-

cessive movement of the spindle when released bythe pawl being prevented by abutting stops 14 carried by the spindle andbase ,plate. For actuating the spindle against the action of the spring a lever 15 is intermediately pivoted between upstanding arms 16 posed thereunder and the rear end of the lever is engaged for depressing movement by an expansile spring 23 carried by an angular arm 24 on thebed plate, this arm also carrying at its horizontal portion an adjusting screw 25 limiting the movement oi the lever, both limits of movement out. the lever being opposed by suitable cushions 26. Adj acent the rear end of the spindle 8, and embracing the same is provided a U-shaped block 27, the arms of which carry a pair of magnets 28 extending inwardly forco-action with an armature 29 carried by the gear sleeve 19, the gear sleeve being normally urged in clutch engagement with the fixed sleeve 20 by a spring 30 on the spindle be tween said sleeve 19 and the rear bearing arm 7. l

Thus upon successive actuations of the magnets 22 the lever 15 will be swung to impart successive rotative steps to the spindle, the lever returning to initial pgsition by reason of the clutch engagement of the sleeves 19 and 20. When it is desired to reset the spindle, the magnets 13 and 28 are simultaneously actuated, to retract the clutch sleeve 19 from engagement with the sleeve 20 and to release the pawl 10. I

The general arrangement heretofore described is shown in my said previous application, and it is also shown, though not in connection with a voting machine, in Patent" No. 1157839 granted to me October 26, 1915. This structure has been described in detail in view of the intimate relation of its various parts to the subject matter of this present application.

lFixed on the forward end of the spindle 8 is a drum 31 and carried atthe forward end of this drum is'a symbol carrying indicating disk 32 similar to the disk of my previous structure and the drum of the present structure carries three contact blocks a.

33 which are disposed at regularly spaced intervals in stepped relation transversely of its periphery and which are selectively engageable with two of a series of five contact fingers carried by a block 35 upstanding at one side of the drum, the outer fingers and the center finger being connected with return wires 36 extending to the vote totaling means hereafter to be described, and the intermediate fingers communicating with a common supply wire 37, these fingers being menace for later convenience termed positive fingers 34 and negative fingers 3413.

By closing a circuit through a selective pair of fingers 34 and 3d the correspondin .total vote recording means will be actuated,

cating means for the photostat mecha nism which is disposed at the rear 01 the bank or indicatin mechanisms, a slidable plate 39 is provide having the vote symbols 10 on its outer face, this plate being slidably mounted by engagement o1 its lower edge portion in a longitudinal groove 41 in the rear side edge of the base plate 5, and by engagement of bracket arms 42 carried by the free ends of the magnet block 27, in a groove 43 formed in an inwardly upstanding flange at the upper edge of the said plate 39. This plate is slidably actuated to selectively expose one of its symbols 40, which symbols correspond to the symbols of the indicating disk 32, by means of a gear segment 14 fixed on the rear end of the spindle 8 and meshing with a rack series of gear teeth 45 on the under face of the said flange, it beingunderstood that the symbols are selectively dis- I played through a suitable casing (not shown).

Referring now to Fig. 7, which shows a diagrammatic assemblage of the entire apparatus, A designates each of a pair of main station indicating mechanisms and B designates each of a pair of sub-stations which contains a switch adapted to actuate either the voting magnets 22 or the releasing magnets 13 and 28. This switch-comprises an intermediate pivoted common contact bar 46 which is engag'eable selectively by voting and releasecontact members 47 and 48 respectively, the commontcontact member betion of the individual voter, and the indieating and release magnets thereof are indicated in Fig. 7 at 22 and 13 and 28 respectively. A new line 19 connects the voting contact member 47, the magnet 22, the magnet 22 and extends to a common supply point 50, from which a line 51 extends to theendmost of a series of batteries 52. A 3

line 53 extends from the release contact member 48 and is branched to include the magnets 28 and 13 and branched to include the magnets 28 and 13 and terminates at the common supply point 50. Extending from the other end of the battery 52 is a common return line 54 which is branched for extension to the contact members 46 of the sub-stations.

Thus upon pressing the voting contact member 47 into contact with the member 46 the current will pass from said member 46. thereto and through the line 49 to the magnet 22 thus imparting a rotative step to the drum 31 and closing the gap between one of the end contact fingers 34 and the adjacent finger, the circuit being completed through the common return line 51 the batteries 52 and the common supplyline 54. To procure other voting indications the voting switch is closed a second or third time.

Taking up now the total vote means, there is provided three ammeters C, C and C and from each of these ammeters a line 55 extends to a respective negative contact finger 34 The positive contact fingers .34 are connected with the branched end of a sup- 1 ply line 56 which is attached to the positive pole of an intermediate one of the series of batteries 52. Extending from the negative poles of successive other batteries are a series of wires 57 terminating in contact points 58, of a multiple switch 59 and extending from the switch lever is a line 60 connected by the transverse wires 61 with "the ammeters C, C and C" and connected with the common supply. line 56, a volt meter 62 being disposed in this line 60 and consequently arranged in multiple with the ammeter circuits. Disposed in each wire 55 is a resistance 'coil 65 which imparts a definite unit of resistance to be registered in a corresponding ammeter, and thus each unit of resistance registers one vote in the ammeter.

The switch 59 provides for maintaining a constant current through the ammeter circuits whereby their indications will be exact,

and the volt meter 62 indicates a constant necessary yoltage which'must be maintained to effect proper indications of the ammeters.

Tracing now one of the ammeter circuits, the current passes from a positive contact finger 34 to the corresponding negative finger 34 through the contact block 33 of the drum 31 and then passes throughthe line 55 with its resistance coil 65 to the corresponding ammeter. From the ammeter the current passes through the wire 61 to the line 60 and thence through the switch 59 and a selective one of the wires 57 to the batteries, from which it passes by the line 56 to the positive contact fingers 34.

The vote indicating lamps 38 of the indicating mechanism are disposed in lines 67 connecting the common return line 51 of the system and corresponding lines 55 between the resistance coil 65 and the contact fingers 34. Thus a circuit for one of the lamps is traced from the batteries through the common supply line 56 to a positive contact finger 34, through a drum contact 33 to a negative contact finger 34" and thence through the lines 67 and the lamps and the common return line 51 back to the battery.

In Fig. 7, 68 designates a pair of magnets for electrically operating the photostat mechanism 69, to procure a permanent record of the indications displayed by the slidable plates 39 at the rear of the indicating mechanisms. These magnets are disposed in a line 69 branched from the main supply- 73 designates a multiple switch, the lever of which is connected with a branch 74 of the main supply line, and the various stationary contact portions of which are connected by wires 75 with the lines 53 at the substations in advance of the reset magnets 13 and 28 whereby a main station means is provided for resetting all of the indicating mechanisms.
