WILLIAM J LAUSTERER, OF JAMESTOWN, NEW YORK, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO AUTOMATIC REGISTERING MACHINE CORPORATION, A CORPORATION OF NEW YORK.

LOCKING MECHANISM FOR VOTING-IVIACHINES.

Application filed October 14, 1913.

To all whom it may concern Be it known that I, WILLIAM J. Laos'rnnnn, a citizen of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Locking Mechanism for Voting-Machines, of which the following is a specification.

The object of this invention is to provide a locking device for controlling the operation of the voting machine, that will permit the unlocking of the voting machine for operation and the subsequent locking of the machine against operation and will then pre vent any further unlocking of the machine for voting operation until the machine is opened and the lockis especially set therefor. This and other, objects of the invention will be fully illustrated in the drawings described in the specification and pointed out in the claims at the end thereof.

In the accompanying drawings, Figure 1 is an elevation of the side of the machine. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Figs. 3, el and 5 are detailed elevations of the locking devices in different positions.

In the accompanying drawings, like reference numerals indicate like parts.

In the drawings, reference numeral 1 indicates the casing of a voting machine in which casing is mounted the inspectors knob 2 having a link 3 attached thereto, which link controls the operation of the our ta-in lever in the manner described in Patent No. 995,424, Gillespie, issued June 18, 1911, see Fig. 54L of said patent.

Pivotally mounted on the side of the easing is a bell crank 1, the lower end of which 5, is adapted to swing in from the inspectors knob and permit the lifting thereof. The upper end of the bell crank is connected to a link 6 which link at its upper end is connected to the stud 7 mounted on the bolt 8 of the lock 9. This lock is controlled by the key 10 in the ordinary manner for the purpose of throwing the bolt 8 to lock or release the voting machine.

The stud 7 has a square shank 11 as is shown in Figs. 3, 4: and 5. The lock is especially fitted with a dog 12 and a trigger 13, both of which are mounted on the lock. The dog 12 has an offset portion 14 with which the lower end of the trigger 13 is Specification of Letters Patent.

adapted to engage. lVhen the dog 12 is moved back to the position shown in Fig. 3, the trigger can be moved back to the position shown in Fig. While in this position, the bolt 8 can be moved up. The shank 11 bearing against the cam portion 15 on the trigger 13 will cause the trigger to move to the right at the top and to the left and up at the bottom. The movement of the trigger to the left and up at the bottom will cause the lower end of the trigger to bear against the offset portion 1% and move the dog 12 back at the top. This backward movement of the dog 12 precedes the upward movement of the bolt 8 with its shank 11 so that the bolt can move to the position shown in Fig. 4. When the bolt is moved down again by the turning of the key, the trigger 13 will remain idly in the position shown in Figs. 4 and 5 but the dog 12 will move to the position shown in Fig. 5, being moved forward by the spring 16. While the dog is in this position, the inspectors knob cannot be raised. As long as the dog remains in this position, voting on the machine cannot be resumed. Access, however, may be gained by the custodian to the inside of the machine and such otlicer can set the parts again in the position shown in Fig. 3 after which the cycle of operations can be repeated.

I claim:

1. In a machine having an inclosing casing, the combination of means for holding an internal mechanism against actuation and means operated from outside of said casing for locking said holding means in operative position, said locking means being releasable only from the inside of said casing.

2. In a machine, releasable means for holding an internal mechanism against operation, means for locking said holding means against releasing movement, means for operating said locking means from outside of the machine, and latching means actuated by movement of said locking means to hold said locking means in operative position, said latching means being releasable only from the inside of the machine.

3. In a lock the combination of a bolt, a stud thereon, a latch mounted to swing on one side of said stud and a trigger mounted to swing on the other side, a lug on said latch ngaged by said trigger to hold the latch out of engaging position, said trigger being engaged by said stud on the forward movement of the bolt to swing the trigger out of engagement with said latch, said latch being adapted to swing into engagement with the stud on the forward movement of the bolt and hold the bolt against a second movement.

4. In a lock the combination of a bolt, a

stud thereon, a latch mounted to swing on 1 one side of said stud and a trigger mounted to swing on the other side, a lug on said latch engaged by said trigger to hold the latch out of engaging position, said trigger being engaged by said stud on the forward movement of the bolt to swing the trigger out of engagement with said latch, said latch being adapted to swing into engagement with the stud on the forward movement of the bolt and hold the bolt against a second movement, a spring pressing said latch forward against the stud.

5. In a lock the combination of a bolt, a stud thereon, a latch mounted to swing on one side of said stud and a trigger mounted to swing on the other side, a lug on said latch engaged by said trigger to hold the latch out of engaging position, said trigger being engaged by said stud on the forward movement of the bolt to swing the trigger out of engagement with said latch, said latch being adapted to swing into engagement with the stud on the forward movement of the bolt and hold the bolt against a second movement, a spring pressing said latch forward against the stud, said latch being first moved back by the movement of the trigger coplel of thin patent may be obtained for five cents each, by addressing the Commissioner of hteltl, washington l).
