June 11, 1929. 1.. MAYER 1.717344 ELECTRIC LAMP SOCKET /NVENTOR ATTORNEY Patented June 11, 1929.
UNITED STATES PATENT OFFICE.
LEO MAYER, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO HENRY COLE COMPANY, 013 BOSTON, MASSACHUSETTS.
ELECTRIC-LAMP SOCKET.
Application filed December 14, 1927. Serial No. 240,060.
My invention relates to electric lamp sockets and particularly to such as are used in connection with automobile lights.
The object of my invention is to produce 5 a lamp socket with a switch located outside of the lamp socket whereby the making and breaking of the circuit is easily accomplished by a simple turn of the switch member.
The invention will he hereinafter consid- 1 ered in detail and specifically claimed. teference will now be had to the drawing forming a part of this application, wherein there is illustrated a preferred emhodin'icnt of my invention, but it is understood that the ele- 1 mcnts thereof can be varied or changed as for shape, size, or form, and various modifications thereof in detail and in the arrangement of the parts may be made by those skilled in the art, without departing from the spirit of the invention.
F ig. 1 represents the improved lamp socket in longitudinal section, certain parts being left in elevation for clearncss.
Fig. 2 shows the same construction of the socket as Fig. 1, except that only one terminal wire is shown, the body of the automobile being used as the other terminal.
Fig. 3 is a section on line 33-43 of Fig. 1. Fig. 4 1s a section on line li of I 1g. 1.
Fig. 5 is a section on line 55 of Fig. 1.
The casing 10, at the left end thereof, is
provided with suitable means such as bayonet joints 11, one of which is shown in dot ted lines, see Fig. 1, to receive pins 12 of a lamp 13 in the usual and well known manner. At approximately midway of said casing 10 is a rotatable plug or switch member 14 of insulating material 15. provided with a metal band 16 surrounding the insulating material 15. A tubular member 17 is located in the insulating material and is held fast theirin. The said tubular member 17 is arranged to house the headml portions of plungcrs 18 and 19, between which is located a spring 20 normally tending to separate them. A terminal plug 21 of insulating material secured on the right end of said casing 10 and preferably protruding therefrom is arran ed to receive the wires 22 rind 23 which enter dioles in metallic cylindrical members 24. and 25.
The tubular member 17 is singularly arranged with the axis of said casing so that the headed portion 18 is always in contact with the lamp 13. The headed portion 19 when in contact with the metallic cylindrical member 24., will complete the circuit. If however the switch member 14 is rotated so that the headed portion 19 is out of contact with metallic member 24, then the circuit is broken. I
The plug 14 has a hand piece 26 extending therefrom, whereby it may be rotated to position the headed portion 19 in contact with the metallic cylindrical member 24 to complete the circuit or remove it therefrom to break the circuit.
When the circuit is completed the current passes from wire 22 to metallic cylindrical member 24, then into the tubular member 17 into the lamp then into casing 10, then through spring 27 and out through wire 23.
From the above description it will be seen that a very simple and inexpensive device is formed, and the making and breaking of'the circuit is accomplished very easily by a movement of the hand piece 26 less than a quarter of a turn.
Having described my invention, what I claim is:
A lamp socket of the class described comprising a casing having means at one end thereof to receive a lamp, a terminal plug fixedly secured to the other end thereof, an electrical contact mounted in said plug and arranged eccentrically in respect to the axis thereof, a rotatable switch member, having spring pressed contact members, said switch member being in angular arrangement with respect to the axis of the casing, one end of the said switch member being in continuous electrical contact with a lamp in said casing and means by which the other contact member may be rotated to make or break the electric circuit.
LEO MAYER.
