Said lever preferably comes against Be it known that I, PETER SORENSEN, a citia stop 9 (see Fig. 1) to limit the movement in zen of the UnitedStates, residing in the borone direction, so as to determine the position bugh of Brooklyn, city and State of NewYork, of the lever with reference to the arm of the 5 have invented an Improvement in Time Out-. latch device.

Usually such foundation has between and in electrical engagement'with been a slab of marble. the clip-contacts e, and the latch-plate 3 of 0. represents a spring-actuated lever, which said switch-bars presses against the springis pivoted to the foundation and preferably actuated plunger 0 to hold the same down in passes beneath the clock-movement, as shown its case, and at the same time the edge of the 5c in Fig. 1. The lever is provided with a spring latch-plate 3 is engaged by the spring-actua for drawing and holding the same in one diated latch device d, and the lower end of the lever a is placed between the rollers 7 and 8 to hold the latch device d into engagement with the edge of the latch-plate ,3. In this position the circuitis complete, and the spring a holds the lever 0. against the stop 9, with the lower end of the lever between said rollers to fix the position of the latch, this being the normal position of the devices while the current is on and before the current is broken or shunted by the operation of the alarm-release mechanism of the clock. The clock alarm-release is fixed for a predetermined period, and when the time of said period arrives the said mechanism is let off in the usual manner, the arm 1, with its pin, striking the upper end of the lever 61 and swinging the same into the dotted position, Fig. 1. As soon as the lower end of the arm a moves out from between the rollers 7 and 8 the spring of the latch device d raises the latch, bringing the rollers together and freeing the engagement of the latch with the edge of the latch-plate 3. The moment this latch-plate is freed by the latch device the plunger 0 comes into operation and forces the pivoted switch-bars Z). out of the clip-contacts e and the momentum carries the switch-bars over and downward into the dotted position shown in Fig. 2, thus breaking the circuit and either putting out the lights run by the circuit or stopping the mechanical devices operated by the current. To remake the circuit, it is only necessary to return the pivoted switchbars to the normal position by hand, in doing which the switch-bars pass between the clip-contacts, the plate 3 presses in the spring actuated plunger, the edge of the latch comes against the stop 4 of the latch-device d, swinging the latch device against its spring and bringing the nose thereof over the edge of the plate 3 and opening the space between the rollers 7 and 8, so that the lever a, moved by the spring a passes in between the rollers 7 and 8, restoring the normal position of the devices in which the electric circuit is made complete.

In the modification shown in Fig. 4 a wire spring is employed in the form of a loop with coiled ends around a rod 10. This rod 10 passes through the contact-support 2, and the doubled part or loop of the wire spring is beneath the switch-bar and the free ends are securely held in any desired manner, This spring is useful to insure the movement of the switch-bars, assisting the spring-actuated plunger in case the same becomes sluggish or more or less inactive in its movements.

In the modification shown in Fig. 5 one or more clip-contacts e are shown secured to the common foundation, and the switch-bar b is shown as engaged therewith when in the swung-over position and in which the crosshead Z) is positively held by a spring-actuated latch h. Fig. (3 is a diagram illustrating this modification and suitable circuit connections therefor, the object being to reestablish the circuit in the line-wires a: xthrough a shunt-line 11 and the clip-contacts e when the switch-bars b are disengaged from the clip-contacts e and are in engagement with the clip-contacts e and the circuit going to the lamp t' or other electric-service system is broken.

Myinvention is applicable for breaking or shunting electric circuits in electric-light or other electric-service systems either for the purpose of putting out the lights at a predetermined period or shutting 0d the current from machinery, the idea being to control the electric service for lights or machinery in connection with stores, hotels, flats, or other places where electricity is employed for lights or power, so that the vendor of the electricity can control the use and prevent the abuse of the service by the customer.
