.lo all 'whom 'is' may connerie: l i

Be it known lthat l, .Canti H. Bissau, a

citizen o the United States, residing at- Syracuse, 1n the county ot Gnondaga and and arrangement of parts to be hereinafter o, a. l on opposite sides of the anis ot the element described and particularly recited in the claims.

@ne exemplilication of the invention is illustrated in the accompanying drawings, wherein:

Figure 1 shows the socket in side elevation. Fig. 2 is a vertical section on line 2 2, Fig. 1. F ig. 3 is a top plan view. F ig. 4 is a vertical section on line 4.-4 Fig. 3; and Figf is a detail view showing principally the arrangement of the metallic parts of the socket.

rlhe invention includes a -one piece element of insulation, and conductor and terminal members associated therewith in such a manner as to bc shielded from the weather and accidental contact with the person, and relieved of the strain incident to the suspension oit' the socket from the conductor mains. cylindrical body portion 2, having a socket in one end, and converging .walls at its opposite end, a cap 3 of greater diameter than the body 2, and a neck constituting an integral connection between the body and the cap. Under surfaces of the cap, on opposite sides of the neck, preferably incline downvardly in parallelism with the converging walls of the body, so as to provide in coaction therewith upwardly converging grooves fl, 5, designed to receive the conductor mains Uritlces 20, arranged parallel to and ot insulation, lead from the bottom of the socket aforesaid through the top of the cap;

suc-li orifices being of larger diameter adja- The one piece element includes a` cent their outer ends.- Horizontal'l passageways 23 leadE through the cap in-opposite directions from the orifices 20, such passageways opening out through the periphery of the cap. and .into the upper 4portions of the grooves 4,5. This one. piece' element of insulation bears the entire' strain incident to thev suspension. of. the lamp from the .conductor mains 6, 7, and supports the metallic terminal andcondu'cting members now to be Pa'tergteeil Aug. 27m-tuig'. y

described; These metallic members include .l

lamp terminals located within the socket -in the body 2, and conductors leading therefrom :tor making electrical contact wit the Shanks are threaded and terminate just. above 4the horizontal' plane-of the' passagey ways 23. The screws are threaded into the inner ends ot' conductor bars 21, 22, one of' which is located in each passage-way 23. The outerends of the bars are deflected downwardly to form lugs 24 which carry threaded plugs 25 having pointed ends designed to make electrical contact with the conductors 6, 7.'

As will be noted, the conductors leading from the terminals 10, 16, to the main con-l ductorst, 7', comprise the screws 13, 17 and conductorbars 21, 22, and the bars are dnplicates, and the screws arc likewise duplicates ot' each other. The arrangement per- .mitting of the use of duplicate bars and screws conduces materially to the inexpeu; siveness and simplicity of the socket. lt will be further noted that the strain or weight of the lamp incident to its suspension from ,the conductor mains G, 7, is not imposed upon the' metallic parts, but is borne by the cap which is integral `with the neck and body of the element ot insulation.

I claim zi l. In a receptacle of the class described, a one piece element of insulation comprising a body. portion having a socket' in' one end, a' cap, and a neck forming an integral connection between the cap and the body, said element being provided with grooves on opposite sides of the neck having opposing walls icc formed by opposing surfaces of the cap and body, and :said element having'parallel orices .extending .therethrough on opposite sides of its axis, and horizontal passageways extending in opposite directions from said orifices through the periphery of the cap, and intersecting with the adjacent grooves, and metallic terminal and `conduct` ing members located in said socket, orifices and passage-ways, all of said metallic mem- .bers being supported by theeleinentof insulation free 'from the strain imposed upon the vterminal members to points adjacent said shoulders, each of said conductors compris- 'ing two members, one a bar extending transversely of the insulating element, and'the other a screw extending in a direction parallel with the axis of the. insulating element,

`the conducting bars being counterparts, and

the screws of the duplicate conductors being also counterparts of each other.

in presence of two 3. ln a receptacle of the class described, a i

single piece of porcelain havingI a socket at one end for lamp terminals, and its opposite end constituting a concentric, overhanging cap, said piece having orifices extending from the bottonro the socket through the cap,v and the cap portion being provided with oppositely extending passage-ways ai'- ranged at right angles to, and intersecting said' orifices, said ,porcelain part being provided with converging channels, or grooves,

for the reception ofthe conductor mains,

each of -said groovesvor channels intersecting 'one of said passage-ways, conductor bars located inthe passage-ways and projecting laterally 'across said grooves, or chaniiels,.

above the conductor mains therein, means on the end' of each bar for making electrical Contact .with the adjacent main conduct-or, and a pair of screws for connecting the inner ends' of said :bars with the -lanip terminals and for holdingsaid bars out of Contact with the main conductors for preventing moisture from entering the receptacle.

ln testimony whereof I aiiix my signature witnesses.
