To all whom it may concern Be it known that I, GILBERT W. Goon- RIDGE, a citizen of the'United States of Afmerairfield, and State of Connecticut, have invented certain new and useful Improvements in the Construction of Incandescent-Electric-Lamp fiockets and the Like, of which the following isa speciiication. m p "M invention relates to the construction ofiticandescent-electric-lamp sockets and the (like, and the obge'ct of myinvention is to provide a means w be more readily attached together and detached than in those constructions'in which screw fastening means. are employed, and

will be no danger of the twoyet so that there parts becoming accidentallyor unintentionally detached from each other. I

In the accompanying drawings, Figure 1 is 'a side elevation, drawn to an enlarged scale, of

the shell and cap detached from each other. Fig. 2 is a section on the line 1 1, Fig. 1. Fig. 3 is a View of the inner face of the cap, and Figs. 4 and 5 are views showing the action of the spring-latch.

. While my invention may be applied to different devices in which a sheet-metal shell is to be attached; to a cap or base part, it is here shown and is more particularly intended for sockets having sheetand capswhich have to be. made attachable and detachable from each other.

A is the sheet-metal shell, and B is the cap,

provided with the usual threaded nipple C.

secure to. the cap by means of this nipple or otherwise a yoke 10 with elastic arms, the outer ends of which lie adjacent to the inner face of flange 13-of the cap. To the outer ends of these elastic arms I secure shouldered pins 14 with enlarged-buttons or heads 15 outside the-cap of a suitable size to be acted ress the elastic arms inwardly in the cap. These shouldered pins, which project through suitable openings or notches 16 in the flange of the cap, each have a part 18 of relatively large iameter. adjacent to the s ring-arm which carries it and a art of re atively small di ameter 17 at the utton end of the pin." On

ereby the cap and shell may,

that edge of the pin which is to fit within the flange of the cap 1 form notches 19 of the form best seen in Fig. 1that is, each contracted at 20 at the mouth of the notch, so as to be just of suflicient size to pass over the contracted part 17,01?- the in; but at the back of this contracted part the notch is made of sufficient width or diameter to letthe part 18 of the pin enter. Thus when the arts are to be lit together the person puts is finger and t iumb on the opposite push -pins to press both spring-fingers'inwardly to the osition indicated'in Fig. 4, and then the s ell is. pushed down into the cap, the contracted part of the notch 19 slipping over and beyond the part1? of the push-pin which is of smaller diameter. Then when the shell has been pushed home the ressureon the springarms is released and t ose arms springs-out wardly a ain to the position indicated in Fig.

5, with the parts 18 of the pins of larger di- 'ameter entering the enlarged parts of the notches 19 in the shell and engaging with the contracted edges 20 of the notches, so as to firmly hold the shell in place. 'VVhen the shell. is to be taken oil again, it can be quickly done by simply pressing on the opposite buttons and drawing the shell out.

I claim as my invention:

1. An incandescent-lain socket, having a cap and shell to be detacha ly connected, one of said parts having spring-arms with radial pins, each with an external push-button and a stem of two diameters, the other part having notches'contracted at the edges substantially as described. I

2. An incandescent-lam socket, haying a cap and shell to be detaclia )ly connected, the cap having spring-arms with radial pins, each with an external push button and a stern of two different diameters, and the shell having notches contracted at their outer edges to cooperate with said pins.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GILBERT W. GOODR-IDGE.
