CIRCUIT-CONTROLLER.

SPECIFICATION forming part of Letters Patent No. 659,244, dated October 9, 1900. Application filed February 23, 1900. Serial No. 6,180. (No model.)

To all whom it may concern:

Be it known that I, ADAM LUNGEN, a citizen of the United States, residing at the city of New York, in the borough of Bronx and State of New York, have invented certain new and useful Improvements in Circuit- Controllers, of which the following is a full, clear, and exact description.

This invention relates to circuit-controllers adapted to be operated in a somewhat-similar manner to ordinary push-buttons or automatically by the movements of a door, the device being then located inthe jamb of the door.

The object of the invention is to provide a device of this character which shall be simple, cheap, and eifective; and to these ends it consists of the detail of construction, which will be hereinafter described with reference to the accompanying drawings, in which- Figure 1 is a side elevation of my improved switch adapted for operation by a door or similar device. Fig. 2 is a sectional view of the same. Fig. 3 is a plan. Fig. 4 is a view of a modification of the invention. I

The parts of the device are mounted upon a face-plate a, which as respects Figs. 1 to 3 will ordinarily be placed in the jamb or frame of a door, the frame being mortised out to receive the mechanism attached to the plate and the plate being let in to be flush with the surface of the door-frame. On the back of this plate a is fixed a frame 17, consisting of.

two side pieces connected together by piece I). In these side pieces is fixed a cross-pin forming the pivot for a circuit-controlling lever c. This lever is forked at one end, as shown in Fig. 3, the ends of the fork being connected bya pin, upon which is a roller 0. The other end of the lever is formed by a piece of insulating material carrying at its extremity a u-shaped metal clip 0 embracing its sides and extending across the under side of the lever. Below this end of the lever and affixed to the face-plate a is a block of, insulating material d, carrying two binding-posts e e, from which extend two metallic blades f f, between which the metal plate 0 is adapted to be forced by theleverc for the purpose of completing the circuit between the two binding-posts. When the end of the lever is removed from the blades, the circuit is tends outward through the face-plate a and,

as respected in Figs. 1 to 3, is adapted to be operated by the edge of the door. This plun ger has a movement at right angles to the faceplate, its bearings being in the faceplate and in the piece I) of the frame. Zspring s surrounds the plunger and tends to ;keep it in its outward or extended position. .To this plunger is rigidly attached a forked arm 1", extending at right angles therefrom and immediately behind the face plate. Across the ends of this forka pin is mounted to furnish a pivot for a lever 75, extending substantially parallel to the plunger and resting against the roller 0' at the end of lever c, it being held in this position by spring u. The face of the lever which bears against said roller is provided with two cam-faces t and i which widely diverge and have the general shape of the letter V.

When the door is open and the plunger thereby permitted to be in its outer position, the extremity of lever 25 is against the under side of the roller 0 and is holding the opposite end of the lever c in engagement with the contact-blades ff. When the plunger is forced inward by the closing of the door, the face of the lever t runs against the roller 0, the lever being thereby forced backward on its pivot until the apex of its cam-faces passes above roller 0, whereupon the tension of spring u, combinedwith the change in direction of the cam-surface of the lever, causes the position of lever c to be reversed and its contact end lifted quickly out of engagement with the contact-blades ff and breaking the circuit. Thus when the door is closed the circuit is open, and when the door is open the circuit is closed, one motion being positively effected by the door, while the other is effected by the spring actuating the plunger.

The same invention is embodied in the construction illustrated in Fig. 4;, wherein parts corresponding to the same parts in Figs. 1 to 3 are given the same letters of reference. In this case, however, the circuit-controller is intended to be operated positively in both directions by pushing upon a plunger, and for that purpose two plungers 0 and 0 are shown, both passing through the face-plate and pivot-ally engaging with a lever q, the lever being connected with cam-lever t.v It will be readily understood that by pushing upon one of the plungers the circuit is completed, While by pushing upon the other the circuit is broken, the condition of the circuit being always indicated by the relative positions of the plungers.

The principal feature of my invention being the construction and arrangement of the cam-lever 1, in connection with a circuit-controlling lever, it is immaterial what form the actuating devices are put in or what special arrangement is adapted for the contacts.

Having described my invention, I claim- 1. In a circuit-controller, the combination of a pivoted circuit-controlling lever, a second lever bearing against one end of the circuit-controlling lever and having a V-shaped cam-surface engaging with said circuit-controlling lever,means for forcing the cam-lever against the end of the circuit-controlling lever and simultaneously moving its cam-surface along said end, for the purpose set forth.

2. In a circuit-controller, the combination of a circuit-controlling lever a plunger, and a pivoted levercarried by the plunger and provided with V-shaped cam-faces, and a spring tending to force the pivoted lever against the end of the circuit-controlling lever.

3. In a circuit-controller, the combination of a circuit-controlling lever provided with a roller arranged parallel to its pivot and a reciprocating V- shaped cam, whose working faces are held in engagement with said roller during its reciprocations.

4. In a circuit-controller the combination of a circuit'controlling lever provided with a fork at one end between the arms of which a roller is held, a plunger, a lever pivot-ally connected with the plunger and having V-shaped cam-faces engaging with said roller, and a spring adapted to hold said lever in such engagement, substantially as described.

5. In a circuit-controller, the combination of a pivoted circuit-controlling lever, a second lever arranged at right angles to the circuit-controlling lever and having reversed cam-faces acting thereon, asprin g holding the cam-faces against the circuit controlling lever and means for reciprocating the second lever substantially as described.

In witness whereof I subscribe my signature in presence of two witnesses.
