ELECTRIC cur-our;

SPECIFICATION forming part of Letters PatentNo. 768,351, dated. August 23, 1904.

Application filed January 21, 1901. San No. 45,986. on mean.) I

To all whom it may concern.- I

Be it known that I, JULIUs OTOURNIER, a citizen of the United States, residing at Schenectady, county of Schenectady, State of New York, have invented certain new and useful Improvements in Electric Cut-Outs, of which the following is a specification.

This invention relates to that class of mechanical cut-outs known as two-button snapswitches, adapted to be set in flush with a wall or switchboard. In these switches the movable contact is actuated in one direction by one push-button and in the opposite direc-v tion by a second push-button, having a snap action imparted to it in each direction of move ment by a spring.

The object of my invention is to improvev embodying my improvements, the switch be ing closed. Fig. 2 is a cross-sectional eleva- Fig. 3 is a longitudinal section showing the switch open. Fig. i'is a plan view with the face-plate removed. Fig. 5 is a top plan of the face-plate. Fig. 6 is a plan view of the supporting-bar with the holes for the attaching-screws omitted. Fig. 7 is an axial section of the rocker and switch arms and hubs. Fig. 8 is a perspective view of one of the switch-arm hubs, and Fig. 9 is a plan view of a switch-arm.

The casing A is of insulating material, preferably porcelain, molded to the proper shape such, for example, as a rectangular box having an open top. In each corner ofthe box is an upright standard B, consisting of a strip of metal having an angular foot 6, receiving a screw '0, by which it is secured to the bottom of the box. The upper end of each standard is bent inwardly to receive a binding-screw D for the line-terminals. An inwardly-projecting arm 5 on each standard carries a stationary spring-contact E, consisting of two independent clips or of a strip of copper doubled into a U-shaped clip and riveted to said arm at the point where it straddles it. The clips at one end of the box have their-open ends upward and those at the other end downward. A rib 0 runs down each end of the box between the standards, one or both of them being continued along the bottom of the box at a. Lying lengthwise on top of the box is a flat supporting-bar F,whose ends project beyond the ends of .the box and are received in shallow grooves in the upper edge of the box. Screws G are inserted through long countersinks a in the ends of the box and pass into the bar to fasten it to the box.

To the underside of the supporting-bar is attached a transverse yoke H,-having' parallel legs 7L extending into the box. In the ends of these'legs is carried a transverse shaft I, on'which is journaled a rocker K and two double -ended switch-arms ormovable contacts L, one on each side of the rocker and each in line with the clips'E on that side of the box. Each switch-arm is carried on a hub M of insulation, havinga polygonal portion on fitting an eye Z at the middle of the switch-arm. An insulating washer M lies between the switch-arm and the leg of the yoke. The rocker carries a stud k, entering I a hole in the hub M and so locking them all together.

' Pivoted to each end of the rockeris a link N, preferably doubled, as shown, and having a broad upper end, by-which it is attached to a button or plug P, extending up through a suitable hole f in the supporting bar F.

When'one of the buttons is pushed in, as

shown in Fig. 1, the switch-arms enter and connect their respective pairs of contact-clips. When the other button is pushed in, the rocker is rocked and the switch-arms are withdrawn from the-clips, as shown in Fig. 3.

In order to give a quick snap action to the switch, so that the switch-arms will be moved into and out of the clips with a sudden jerk, and thus lessen the danger of drawing an arc, the middle of the rocker has a beveled lug 70, whose two edges are i'nclinedin' opposite directions at the same angle to the upper edge of the rocker. A detent-plunger R, having at its lower end two inclined edges adapted to sunk holes through which the buttons P project.

} By removing the face-plate the circuit connections can be easily made, the leading-in wires being led up through the holes a; in the corners of the wall of the box to the bindingscrews at the tops of the standards. Moreover, when the face-plate is off all parts of the switch can be readily inspected and tested, and the mechanism can be removed from the casing, if desired.

I/Vhat I claim as new, and desire to secure by Letters Patent of the United States, In a cut-out, the combination with a \'ol\'e,

of a rocker rotatably journaled therein and having a beveled lug, a bar extending across the yoke, a plunger passing through the bar and engaging with the lug, and a spring pressing on the plunger.

In witness whereof I have hereunto set my hand this 18th day of January, 1901.

JULIUS C. 'IOURNIER.
