LUTTRELL H. STUART, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO NECTER ROUSSEAU, SR, OF CHICAGO, ILLINOIS.
INCANDESOENT-ELEQTRIC-LI GHT SOCKET.
SPECIFICATION forming part of Letters Patent No. 778,383, dated December 27, I904.
Application filed August 14, 1903. Serial No. 169,423.
To all whom it may concern:.
' Be it known that I, LU'ITRELL H. STUART, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Incandescent-Elsetric-Light Sockets, of which the following is aspecification.
This invention relates to incandescent-electric-light sockets, and has for its object to do away with the usual key to turn the current on or oif. This object is accomplished by producinga switch in the fixture, said switch being operated by turning one of the parts of the fixture, as more fully described hereinafter. I p
In the accompanying drawings, Figure 1 is a plan view of the fixture. Fig. 2 is a plan view with the outershell or casing removed. Fig. 3 is a longitudinal section. Figs. 1 and 5 are plan views of the meeting faces of the two parts or members of the socket, and Fig. 6 is an end view of the inner member.
Speaking generally,-the device comprises two members, one of which islfixed to the base piece or holder, which is screwed onto the wall or other fixture which supports the lamp, and the other of which. is rotatable with respect to the fixed member, there being contacts between said members which make or break the circuit.
Referring specifically to the drawings, 6 is the brass thimble or base-piece of an Edison incandescent lamp, which is screwed onto the wall-fixture or the like, and 7 is the barrel containing the socket-piece 8, into which the lamp 9 is screwed. The barrel is wholly exposed, so that it may be readily grasped to be turned. This avoids taking hold of the bulb.
Within the thimble is the relatively stationary porcelain block or member 11, fixed to the thimble by screws 12. Within the barrel is the relatively movable porcelain block or member 13, fixed to the barrel by the screws 14:. The socket 8 is fastened to the block 13 by screws 15, one of which connects with a Segmental contact-piece 16 on the inner side of the block. The block 11 carries a spring contact-piece 17, which is adapted to contact with the piece 16 when the parts are turned to the proper position for that purpose, and
said piece 17 is connected by a screw 18 to one of the supply-wires 19.
The parts are held together by a screw-rod 20, which passes loosely through the movable block 13 and into a binding-nut 21 on the inside of the block 11, where it is connected to the other supply-wire. The head of the screw forms a contact for the central or inner terminal of the lamp and the socket-piece 8 for the outer screw-terminal thereof.
The circuit may now be traced from a supply-wire 19 through the rod 20 to the inner terminal of the lamp, and when the lamp is lighted from the outer terminal thereof to the socket-piece 8, the screw 15, contact-pieces 16 and 17 and screw 18 to the other wire.
To put out the light, the barrel and block 13 are turned on the rod until the contact between pieces 16 and 17 is broken. Notches 22, into one of which the free end of the spring-piece 17 falls when the lamp is turned on or off, prevent unintentional turning on movement of the parts.
The socket and switch thus produced are keyless and well adapted for the purpose intended.
What I claim as new, and desire to secure by Letters Patent, is
An incandescent-electric-lamp socket, comprising a relatively fixed thimble, a block of insulating material fixed therein, an exposed relatively movable barrel, a block of insulating material fixed therein, switch contactpieces carried by said blocks and arranged to open or close the circuit when the barrel is turned axially, a conducting-rod connecting and extending through said blocks and on which the barrel and its block may be turned,
- said rod having at the outer end one contactterminal, a lamp-socket secured to the block in the barrel and forming, the other contact terminal, and a conducting connection between the socket and one of said contactpieces.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
LUTTBELL H. STUART.
