SOCKET FOR INCANDESCENT ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent No. 642,825, dated February 6, 1900.

Application filed September 16, 1899. Serial No. 730,6 72. (N0 model.)

To 60% whom it may concern:

Be it known that I, WILLIAM E. A. M. 0m- TING, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Sockets for'Incandescent Electric Lamps; and

I do hereby declare the following to be afull,

clear, and exact description thereof.

My invention relates to sockets for incandescent electric lamps, and has for its object to provide a cheap and simple means of attaching and removing the cap from the body of the socket.

My invention consists, generally stated, in the novel arrangement, construction, and combination of parts, as hereinafter more specifically set forth and described, and particularly pointed out .in the claims.

To enable others skilled in the art to which my invention appertains to construct and use the socket, I will describe the same more fully, referring to the accompanying drawings, in which- Figure 1 is a side elevation of an incandescent electric lamp having my improved socket applied thereto. Fig. 2 is a like View showing the cap removedand ready for inserting over the socket-body. Fig. 3' is'a cross-section of the cap on the line 3 3, Fig. 2, looking at the bottom of the same; and Fig. 4is a top view of the body of the socket.

Like numerals herein indicate like parts in each of the figures of the drawings.

As illustratedin said drawings, 1 represents the incandescent electriclamp of the ordinary approved construction and composed of the glass bulb or globe 2, which removably fits within one end of a sheet-metal socket 3, having its opposite end provided with a sheetmetal cap 4. The socket 3 is provided with the body portion 5, which is circular in crosssection and has at the open end 5, opposite the globe 2, a series of spring-catches 6. These spring-catches 6 are formed by cutting lengthwiseinto the metal of the body portion 5 of the socket a sufficient distance from the open end 5,as at 8, and then bending down the end of the metal between the cuts 8 to form the flanges or lips 9 on the catches 6. If desired, the catches 6 can then be reinforced or bent outwardly from the face 6 thereof, as at 10, so as to extend or project slightly beyond the face 5 of the body portion 5 of said socket 3. The

cap 4 is provided with the ordinary flange 4 thereon, which fits down over the open end 5- of the body portion 5 of said socket 3 and has a series of openings or slots 11 formed or cut therein at right angles to the cuts 8 in the body portion 5 of the socket 3.

The use and operation of my improved socket for incandescent electric lamps is as follows: After the globe 2 has been inserted within the socket 3 of the lamp 1, which contains the device for holding the wires and the other parts for operating the lamp 1, and it is desired to place the cap 4:, encircling the wires, onto the body portion 5 of the socket 3, all that is necessary is to insert the open end 5 on the body portion 5 of the socket 3 within the flanged of the cape and bring the slots 11 in said flange 4 opposite the springcatches 6. The operator can then force inward the catches 6 by pressing with his fingers on the bent portions lQthereof, when the flange 4: on the cap 4 can he slipped or pushed farther onto the body portion 50f the socket 3, which will allow the lips 9on the catches 6 to spring into the slots 11*on the flange at of the cap 4: and secure said cap 4' on the said body portion 5-of said socket.

In caseit is desired to remove the cap4 for any purpose all that is necessary is for the operator to press with his fingers against the catches 6, which will cause said catches 6 to be'forced inwardly and free the lips 9 thereon from the slots 11 in the flange i of the cap 4-, when the cap 4 can be removed from the body portion 5of the socket 3 and so allow the catches 6 to spring back to their normal positions. The slots 11 in the flange 4 of the cap 4 are made slightly longer than the lips 9 on the catches 6 in order to give suflioient play for the lips 9 therein, and when the outwardly-bent portions 10 on said catches 6 are used they act to enable the operator to press the catches inward more easily and does away with the cutting oft-he bayonetthe spirit of the invention or sacrificing any,

of its advantages.

What I claim as' my invention, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, an in candescent-electric-lamp socket having its tubular body portion formed of sheet metal, spring-tongues formed Within and as part of said tubular body portion, and flanges orlips on said tongues adapted to engage with openings or slots in the flange of the cap to hold the same in place on the socket.

9. As a new article of manufacture, an incandescent-electric-lamp socket having its tubular body portion formed of sheet metal, spring-tongues formed Within and as part of said tubular body portion, said tongues having outwardly-extending bent portions thereon, and bent flanges or lips on said tongues adapted to engage with openings or slots in the flange of the cap to hold the same in place on the socket.

In testimony whereof I, the said WILLIAM E. A. M. GETTING, have hereunto set my hand.

WILLIAM E. A. M. OETTING.
