T0 att wllomiil may concern.'

Be it known that I, 'FRANK E. SEELEY, a citizen of the United States of America, residing in the city of Bridgeport., in the county of Fairfield, in the State of Connecticut', have invented certain new and useful Improvements in Incandescent Lamp Sockets, of which the following is a specification.

My invention relates to incandescent lamp sockets and the like, and particularly to the f means of fastening together the shell and the ca the ob'ect of my invention being to provic e a rea y and secure means whereby the parts may be attached or loosened.

In the accompanying drawings Figure 1 is a side view of the cap and shell detached; Fig. 2 is a perspective view of the same with the cap inverted; Fig. 3 is an interior view of the ca Fig. 4 is a cross section on the line 4 4, Fig. 3; Fig. 5 is a cross section on the same line but showin y the cap tilted back preparatory to removal; Fig. 6 1s an enlarged cross section on the line 6-6, Fig. 4; and

Fig. 7 is a side elevation of a modification of` the cap lReferring to the drawings', the cap A and the shell C are made of any lsuitable material but referably of the usual drawn sheet meta The cap is provided with the usual circumferential flange B Within Which the shell fits when the )arts are attached.

My fastening evice is as follows -A spring tongue 1 is attached to the cap rim by rivets or otherwise, as shown in Fig. 1, or is cut from the rim as shown in Fig. 7. This tongue is provided on its inner face with a projection 2 forming a beveled catchwhich may be conveniently stamped from 4the tongue itself.

Atpoints on `the rim of the cap approximately opposite to the tongue are rovided two adjacent angled pro'ections 4 acing in opposite directions, each aving one side approximately parallel to the axis of the socket and one side in a 'plane a proximately at right angles to said axis. hese projections may be conveniently made by stamping the same from the inner face,` of the rim ofthe cap, as shown in the drawings. A

In the shell atappropriatepoints are provided holes 5 of sultable shape to receive the ceive the projection 2 on the tongue.

projection-s4 on the rim and alcole 3 to rel When the cap is fitted upon the shell the projections carried by the cap latch into the corresponding holes'in the shell, and the cap cannot thereafter be either rotated' or moved except as hereinafter explained. The rota-v turned, while the faces b of these projections 4 and 2 prevent the shellfrorn being removed endwise from the cap` The shell may be removed, however, if the tongue l-carrying the y projection 2 be first sprung away from the she l by means of the finger or any instrument inserted under the llared end1 6 of the v tongue and the projection 2 thus lifted free of the hole 3. The ca) may be then tilted back until the faces of t e angled projections 11 are clear of the holes 5. The cap is thereby entirely freed andmay be removed at Will.

I claim as my invention l. An incandescent lamp socket, having a flanged cap and a shell, adapted to fit within the flange of the cap, and means for attaching the shell and cap together, said means including two oppositely faced angled projections formed directly on one part While the other part has holes to'receive the said projections.

2. An incandescent lamp socket, having a flanged cap and a shell, adapted to iit wi thin the ilange'of the cap, and means for attaching the shell and cap together, said means including two oppositely faced angled projections formed directly on one part, while the other part has holes to receive said projections in combination with an additional latching means preventing endwise motion ,catch borne by one part and .faced angled projections borne by one part, the other part having holes` to receive the angled projections and the beveled catch.

4. An incandescent lamp socket, having 8.
