Application filed June 5, 1920. Serial No. 385,786.

ot' which the following is a full, clear, andV exact description.

-f rllhe present invention relates to new and useful improvements in lamp sockets, and

it pertains more particularly to a new and novel method of constructing a lamp socket and a new and novel `arrangement ot vthe contacts thereof y Y It is one oli' the primary objects of the invention'lto construct a lamp socket in such a manner -that its cost Voit manufacture is `Vmateriallylessened.v f

1t is a further objectoii the invention `to construct a lamp socket in such a manner that 'thelead wires thereof'are infactual contact with the contacts of the lamp globe when the latter is positioned therein.

It is a still further object ol' Lthe present invention to so construct a lampsocket that one of the lead wires forms the means for supporting the lamp globe within the socket..

It is a still further object of the invention to s0 construct a device ot' this character as to make it especially adaptable for use in various positions in which it will be exposed to the weather. y f

Vith the above and lother" objects in view,

ings in whichy s Figure 1 is a sectional view taken on the line 1-1 of Fig. 2 and v f Fig. 2 is a front elevation of the lamp socket.

Reterringinore particularly to the drawings the device comprises a base 5 and proreference is had to the accompanying drawf Y 'ectin forwardlv from said base is an ar nate Harige 6, said flange serving to Adeline -a recess 7, the bottom or lower side of which is open as indicated by the rete'renceeharacter 8. This base is formed of porcelain or other suitable non-conducting-materiah and it is provided at two opposite points with lateral ears orthe'like 9, perforated as at 10 rto provide means by which the Posi-V socket is attached to its support. tioned concentrically and suitably secured therein in the baseY of the recess 7, is lablock -11 provided withtwo oblique passages 12 and 13. Leading into-the passage 12 isla conductor 14, and leading intothe passage` Vand in whichthere are a minimum '13 is a' conductor 15. The conductor 14-r is providedv with a flat looped end 16 positionedjon the outer tace 17 Loi" the block .11. As shown more clearly in F ig. 2, the looped end 16 ot the conductor ltis preferably circular in form. l

rl' he outer end Vof the conductor 15 is coiled as indicatedby the reference character 18, and the convolutions ot the -coil 18 are so formed as to receive the screw-threadedend or plug 19 oi the globe 2O of an incandescent lamp.

looped'end 16 of 'the conductor beyond 'the' outer tace ot block 11 in order to prevent short-ci'rcuiting-in the socket. Y

The ldevice operates in the following 11s more clearly shown Y1n'1`1, .'1',-.this coil 18 is spaced trom the volution oi: 'the coil 18, and upon turning-liz the globe 2G, it; will be seen that the several convolutions'of the coil 18 will cause `movement of the plug end 19 of the' globe Yinwardly ot the socket until its inner endl engages with the looped end 16 of the conductor 14.

With fthe several parts in this position, it will be apparent that a circuit is established between the conductors 14.- and 15,

through the filament of the incandescent lamp, thus causing an same. Y

The device is preferably positioned with respect to its support as shown in Fig. 2, and when so positioned, it will be seen that illumination of' the -thearcuate `flange 6 forms a protection against the weather for the several interior parts of the socket, by serving as a water shed therefor'. l

From Ythe foregoing it will be seen that the present invention provides anew and improved form of. lamp socket in which the cost ot manutacture is materially lessened,

of parts.'
