LAMP-SOCKET.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed 12, 1903.- Srial No. 432,386.

To all whom it may concern: H W

Be it known that I, HENRY E. REi'z vrI, citizen of the United States, residing at New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Lamp-Sockets, of which the following is a specification.-

My invention relates to improvements in sockets for incandescent lamps and similar constructions.

The main objects are to provide a cheap but durable construction in which the parts of the socket 'an be readily assembled and disassembled without injury or unnecessary wear. These objects are attained by the structure illustrated in the accompanying single sheet of drawings and hereinafter more fully described and claimed.

The two parts bf the socket which will be referred to as the base or cap and the sleeve are adapted to telescope into each other and snap together in such a manner that they can be readily separated when necessary or desired The base has two parts of its edge bent over to provide catches and the sleeve has two shoulders adapted to be engaged by said catches.

Figure l, is a vertical sectional view of a socket embodying my invention. Fig. 2, is a side view of a fragment. Fig. 3, is a fragmentary horizontal section on the plane of line X X Fig. 1. Fig. 4, is a view'of the side opposite that shown in Fig. 2. Fig. 5, is a fragmentary horizontal section of the sleeve on the plane of line 3 y Fig. 1. Fig. 6, is an end view of the base showing the catches. Fig. 7, is vertical sectional view of the same. Fig. 8, is an end view of the sleeve.

Fig. 9, is a vertical sectional view of thesleeve. Fig. 10, is a side view of one side of a sleeve for whatis known as keyless socket. Fig. 11, is a side view of a modification of sleeve. Fig. 12, is a horizontal section. Fig. 13, is a vertical section of same. Fig. 1 1, is a detail view of a modific'ation.

The base 1, and sleeve 2, are formed of metal of suitable form and design. A lining 3 of insulating material is preferably provided. The socket of Figs. 1 to t) inclusive is for what is known as a key switch and the sleeve has a wide slot 1. The metal on each side of this slot is turned in to form

flanges

5, 5 to hold the lining in place and preye-nt its turning. This slotting of the sleeve also rendersit. yielding for purposes 1 of assemblin and disassembling as will be described. g

Uri opposite sides of the base 1. limited portions of the edge are bent, flanged or drawn over to form

catches

6 and 7, having 1 abrupt inner edges forming engaging shoull ders. Corresponding shoulders S and 9 are formed at opposite sides of the sleeve 2, by slitting, cutting or indenting the metal for instance at 16. The parts are separated by compressing the sleeve adjacent shoulder S and thus disengaging catch (3. The sleeve can then be drawn out readily.

Alining'tho parts is rendered easy by pro viding a guiding projection 11 and a recess formed by boss 12. Assembling is facilitated by turning in the corners 1 3, 13

slightly and bending in the opposite edges 14: (see Figs. 8 and 9) so that the sleeve will more readilytelescope into the base. Preferably, catch 6 spans the slot 4, (see Fig. 2) and thus assists in preventing relative rotation of the parts. I11 the keyless socket of Fig.10 the slot 4 is provided in order to render the sleeve yielding (so that all parts may be put together and separated readily) Instead of the projection 11 and corresponding recess beneath boss 12, I may indent the sleeve as at 15 (see Figs. 11 12 and 13) to form a groove for guiding the catclrfiange 7. A shoulder-'9 is also provided for engagement by the catch 7 In the form of shell for a socket, as shown in Fig. 14, the shoulder 8 (corresponding to shoulder 8, Figs. 2 and 10) is formed by slitting and indenting a part 16. The large slot 4 is primarily for the purpose of accommodating the key of the ordinary switch (not shown) but it provides a yielding wall in which one of the shoulders, such as S, S or 9 should be located. The parts may also be assembled by simply hooking shoulder 9 back of catch 7 and then swinging the sleeve over and snapping shoulder 8 back of catch 6.

\Vhat I claim is:

1. In a lamp socket, a cap member having a limited portion of one edge turned inward to form a catch serving as one member of a hinge, and an inwardly projecting catch opposite thereto and a. shell member slotted at one side .to provide a yielding portion and having a locking shoulder in said yielding portion and a second locking shoulder opposite thereto, one of said shoulders serving as a second hinge member companion to the inturned catch at the edge of the cap member E and the other shoulder cooperating with said inwardly projecting catch member whereby when said hinge-like members are interengagcd the cap and shell members may. be relatively swung together until the shoulder and catch opposite the hinge snap together substantially as described.

2. A socket comprising a cap having a plurality of limited portions of its edge turned inwardly and forming catches, a lon gitudinally slotted sleeve having aplurality of shoulders corresponding to said catches, one of said shoulders being at one side of the slot in said sleeve, the corners of the sleeve at themonth of said slot being inclined inwardly to facilitate alinement and assembling of the sleeve in the cap, said catches when interlocked with said shoulders preventing longitudina-l j and rotative movement of the parts. v

3. A socket comprising a cap having an inwardly projecting shoulder atone side and having one edge turned in at the opposite side, a. slotted sleeve having a shoulder at one side of the'slot and a second shoulder at the opposite side of the sleeve the inturned edge of the cap spanning the slot and extending to the shoulder thereat.

it ae ase i. A. socket comprising a cap having in \vardly projectingcatches, a sleeve having shoulders to co-act therewith, the edges ot the sleeve adjacent said shoulders being inwardly bent to facilitate telescoping with the cap.

A socket comprising a cap having portions of the edges turned over to form inwardly, projecting catches, a sleeve having shoulders toco-act therewith, the edges of the sleeve adjacent said shoulders being in wardly bent to facilitate telescoping with the cap. V

6. In a lamp socket. a shell member having a longitudinal slot and a notch affording a shoulder a one side of said slot and a second shoulder opposite the slot and a cap member having a portion of one edge turned inwardly and serving as a catch extending across said slot and into said notch and engaging the shoulder thereof and a second catch opposite the first catch and interlocking with the second shoulder substantially as described.
