Application filed'lebruary 9, 1927. Serial No. 167,044.

This invention relates to'electric connecters used in connecting electric conductors together, and has special application to electrio connectors used withautomobile lights.

The object of my invention is to provide simple and effective means for making and breaking the circuit.

Another object of my invention is to provide a simple and effective means for making and breaklng such a circuit and is applicable equally alike to electric lights havin-ga one wire system, a two-wire system, and to a system which is partly one wire and partly two wire system.

The invention wiltbe hereinafter considered in detail and specifically claimed. Reference will now be had to the drawing forming a part of this application, whereinthere isillustrated a preferred embodiment of my 2 invention, but it is understood that the elements thereof can be varied or changed as for shape, s ze, or form'without departing from the spirit of the invention.

Fig. 1 is a sectional view of a two, wire electric system embodying my invention.

Fig. 2 is a sectional View of an electric system which is partly one wire and partly two wire system, embodying my invention.

Fig.3 is a sectional view of one wire electric system embodying my invention.

Fig. 4 is a view on line 4-4 of Fig. 1. Fig. 5 is a view on line 55 of Fig. 2. Fig. 6 is a view on line 6-6 of Fig. 3. Fig. 7 isa view on line 4-4 of Fig. 1 showing the position of the switch and wire when electric contactis made. In my drawings, referring to Fig. 1: 10 represents an incandescent light or bulb mounted in the shell -11 which is provided with bayonet slot 12 to receive the stud 13 or the bulb. The shank of the lamp is provided at its inner end with two-contacts 14 and15. These two contacts make electrical contact with the ends of the spring pressed plungers 16 and 17, of a well known construction. The rods 18 and-19 have extensions 20 and 21-which are connected to thelead wires. The rod 18 is divided into two parts 22 and 23. i w.

The shell 24 has an openin 25 therein through which the handle 26, w ich is made of nonconducting material, passes. The shell 24 is provided with extensions 27 and 28,

which have openings 29 and 30. The handle 2G is pivotally connected to the shell by means of pin- 31. The head of the handle is fore thehlectric circuit is broken. Vhen it is desired to make the electric circuit the handle 26 is rotated counter clockwise. The ca|n- 33 comes in contact with the ribbon 2 and moves the ribbon so that it makes contact with the rods 18 and 19 and the .cir-

cuit is thereby established. To break the circuit the handle 26 is moved in the opposite direction and the resiliency of the' ribbon forces it away from the rod and the circuit is broken.

The cam mechanism used to make and break the circuit described above is used also for making and breaking the electric circuit shown in Figs. 2 and 3. In Fig. 2 the ribbon 32 is moved so as to make contact with rod 34. In Fig. 3 where one wire electric system is shown, the circuit is made and broken on the rod 35.

From the above description it will be seen that I use a simple and positive means to make the electric circuit. To break the circuit, the resiliency of the metal is used.

Having described my invention, what I claim is:

In an electrical lamp receptacle, the combination of a tubular shell, a base member located in one end of said shell, a vertically located cont-act member longitudinally located with respect to said shell and located in said base member at one side thereof. a second contact member located in said base member on the opposite side thereof, the longitudinal axis of which is obli uely disposed with respect to the longitu inal axis of said shell, a switch member pivotally mounted in the side of said shell and operatively disposed at ninety degrees to the vertical axis of said vertical contact member, a spring contact member transversely dispassing outward and, at the second point 5 passing inward after which the remaining end is bent outward against the inner wall of said shell, the opposite end of said spring contact member adaptedto .be pressed into contact with said vertical contact member by means of a camsurfacelocated on the inner 10 portion of said switch member, substantially as shown and described.

' LEO- MAYER.
