LAMP-sooner.

To all whom it may/concern; v f Beitknown that I, WILLIAM C. TREGQN-l ING, a citizen of the UnitedStates, residing atCleveland, in thecounty. of Cuyahoga and lState of Ohio, have invented certain new and Iuseful Improvements in Lamp-Sockets, and

do declare that the 'following is aful1, clear,.

and exact description 'of theinvention, which will enable 4others skilled in the art to which -it a pertainsto makeand use the same. l his invention relates to lamp sockets, and

the invention conslstsina ,socket more es pecially designed to be used-fin eleotriclight signs employing metallic casin s, but adapted to. various combi-nations an poses, lall Asubstafritiadly as' shown a,r' 1d^- de5A scribed and particularly pointedeutin the claims. L y,

Thus, the said socket member- -or socket proper is vpreferably of porcelain Vbut may be of any suitable nonconducting materialg'and is of the shape and outline vparticularly shown in Figs. `1t, 5 and 6, respectively, the distinguis hingv features of whlch are the opposite-"bearing ribs 2, which have Hat or substantially ila't faces adapted to lie against wall b if-metallic casing B and which ribs have suchdept'h and .length as to aiord a sufficient spacing portion for socket l Y C to make room for the means required to secure conducting' wire Dupon said socket and keepthe fastening or connectingplate or part d' from Contact with said-case.'

Vand as intermediate means for fixing the shell yfirmly in socket fC. Asuitable washer 16 preferably of asize tol overlap base'of shell E serves as a bearing'ior lthe head of screw 8 on said disk`12, and conductor g becomes also fastened' thereby. n `this connection it wi be noted that conductor member d lies within a semi-circular recess -17e`- upon the' inner face' ofy closed end c of socket C and (conductor member g to the rear thereof with end wall Vc between, and Vrecess 6 provides' screw 8 as well asbeingmeans of entering conductormember g into place so thatl screw 8 may fasten all said.

A cross portion orzbacking part 9 ot socket end c supports member g at `1ts free end against rear pull or strain and arate conducting members front and rear of said cross Wall and seated within said lateral openings, and a central screw and insulating disk jointly securing all said parts togethe 2. An insulating socket member for lamps and the like having oppositerecesses through the wall thereof and a recess in its rear face and a cross portion bridging said rear recess, in combination with current conductors fixed in said recesses and constructed at their outer ends to engage the line wires, a conducting shell within said socket bearing upon one of said conductors to hold it in lace, an insulating disk within said shell anci)a single fastening and conduct-ing member ada ted to secure said parts in their respective p aces Within and upon said socket member.

3. A socket for lamps and the like cnstructed of insulating' material and provided with opposite openings through the wall thereof, and having a part circular recess within its inner end, conductors fixed in said openings having their outer portions constvucted to fasten the conducting wires thereto and one of ysaid conductors formed to seat within said recess, a conductinef Ashell insaid socket in electrical contact with one of said conductors, an insulating disk Within said shell, andv a conducting screw centrally of said socket member adapted to fasten said disk and shell and both said conductors upon vsaid socket.

4. In electric lamps, an insulating socket of circular formation having `protecting ribs on its outside and lateral opemngs at the' end of 'said ribs opento the interior of the socket, in combination with conductors mounted in said openings having their outer ends terminatiiig below the outer face of said ribs and adapted-tomake connection with the circuit wires, a shell bearing upon-one of said conductors, an insulating member -Within said shell, and asingle fastening member securing saidjparts to theother conductor and the socket and providing a central contact for the lamp.

5. An electric lamp socket having conducting members for the line connections and a metallic shell in said 'socket engaged with and bearing upon one of said conductors `and a central screw and insulating'member 65 fixing said shell and said conductor in place, saidscrew being threaded through the other of said conductors, which serves as a nut for said screw and secures said parts jointly togetlier.

6. An electric insulating socket having a closed endxand lateral openings therein, in 'combination with a receiving shell, and wire fastening and conducting members mounted upon the inner and outer faces of said closed 75 end and projecting outwardl through said lateral openings, and asingle 'astening mem# ber jointlyv securing said conducting members in their respective places upon said socket.

` 7. A socket member for lamps and the like having lateral openingswithin its sides and a circular recess within its bottom and recesses at its rear foraccess in making connections, in combination with a conducting shell,'an 85 insulating disk Within said shell, a art circular conductor adapted to seat within said circular recess and project through one4 of said vlateral openings and bearing .against said shell, a second conductor seated within said WILLIAM" C.
