GILBER w. GOODRIDGE, or BBIDGEPORT, oon vncTIc T, ASSIGNOR TO THE BRYANT ELECTRIC COMPANY, OF smncnron'r,..-commcTIoU A CORPORATION or con- NECTICUT.
To all whom, it may concern Be it known that I, GILBERT W. Goon- RIDGE, a citizen of the United States of America, and residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Electric Switches, of which the followingis a specification.
My invention relates to electric switches and particularly to the type of switch adapted to be mounted in an electric lampv socket, the-object of my invention being to provide a simple and efficient mechanism of improved type.
In the accompanymg drawings, Figure 1 is a vertical section through a lamp socket in which my invention is embodied in one form; Fig. 2 is a plan of this switch mech anism in position on one of the buttons forming the socket body; Fig. 3 is a vertical section through the switch mechanism on the line 33, Fig. 2; and Fig. 4 is a perspective bf certain of the switch parts separated. Fig. 5 is an end elevation of the switch spindle showing the position of the operating cams thereon.
The present switch is of the type in which an oscillating switch piece is rocked on its ivot by a switch spring, one end of which 1s shifted to one side'or the other of the axis of oscillation of the switch piece, by a manually controlled operating mechanism. The socket in. which the switch 'is here embodied comprises the usual casing cap 5 and shell 6, with insulating lining 7. The socket body of insulating material is formed from two buttons A and B united by screwbolts 8 and recessed on their meeting faces to form a switch chamber 9. Lateral recesses 10 and 11 accommodate the wire terminals 12 and 13, one of the latter being in constant connection with the shell terminal 14 of the socket, and the other in constant connection with the switch terminal 15. The other switch terminal 16 is preferably formed in one with the center contact 17 of the socket and is secured with thelatter by the rivet 18 in known manner.
Within the switch chamber 9 is mounted the switch frame 19 held in position by the screw 20. While the frame may be of any suitable form, that here shown is shaped from sheet metal bent to form end u rights 21 and side uprights 22. Outward y projecting lugs 23 on the latter serve as pivots the rocker 28.

by the switch spring 25 mounted on the plunger 26 and bearmg at one end against.
the closed end of the yoke (through which The oscillation ofthe switch iseffected' the end of the plunger passes) and at its gaged in any suitable manner, for example,
other end against the head 27 of the plunger. 1 The latter is subject to the vertical move ment of the rocker '28, with which it is en-' by means of a sort ofbayonetslot jointbe tween the slot and aperture 29 in the head- 27 and the cross bar 30 formed in the end of the rocker. Obviously as the head of the plunger is shifted past the axis of oscillation of the switch piece-24 in one-direction or the other, the spring 25' is not only further tensioned, butv its efl'ort is directed to throw the switch yokeinto either the Olf or on po'sition, -a s may be, depending upon the side ofthe axis ofoscillation to which the head 27 of the plunger has been shifted. The movement of the plunger, as above stated, is controlled by the rocker 28, ,the
axis 31 of which is pivoted in-the side uprights of the frame; The rocker in turn is subject to the rotation of the switch key 32 on the spindle of which are mounted, at right angles to each other, the two cams 33 and 34 spaced apart and bearing, in assembled condition, against the lower face of therocker 28 on opposite sides of its axis of oscillation. In the position shown in Fig. 3, the head 27 of the plunger has been depressed through the action of the cam33. on On a quarter turn of the switch key the cam 33 becomes temporarily inoperative, while the cam 34 turning into vertical vposition tilts the rocker 28 in the opposite direction, thus lifting the head 27 of the plunger. A further quarter turn of the switch key restores the switch to its first position throughthe action of cam 33, and so on. Inasmuch as the cams aredouble acting, a quarter turn of the switch key in either direction brings one or the otherv of the cams 33, 34 into eifective operation to oscillate the switch piece through the tilting of the rocker 28.
means thereon for tilting said rocker to shift said end thereof past the axis of oscillation of the switch piece.
