Tn sockets of the iin'esrnt type it. has been the. enstomanv practice to rel rupon the insulating character of the camlehdnnm tube whirh sari-(mods the socket shell to alford the necessary insulation which protects the installation from accidental contact with conducting parts. Inasmuch as these candelabrmn sockets are ordinaritr of porcelain or glass they afford ellicient protection to this end. The eonnnon eandelabrmn inbes are thus rather fragile and it has been proposed to substitute therefor metallic or enameled metal tubes for the same purpose. Inasmuch as this introduces a possible element of danger into the installatiol'i by reason ol" the conducting. nature of the. metal it necessary to provide an insulator between the shell of the socket and the ('alnlelaln'um 1 ulnto prevent contact between the same.

in the embodiment oi my invention illustrated. l have shown a socketl ody 10 comprising the usual insulating button rarr f ing on its l wer fare an internally threaded invention 'thimble 11 which screws upon the upper end of the wire ronduit 12 through the holes 3} in which the wires It and 15 are. led to the binding serew terminals 16 and t? on the upper surface of the socket body.

To insulate these parts from each other I provide aniasnlating easing 2 sue rounding the sorket shell 19 and in the present form secured thereto by a threaded portion 24 formed between the ends of the ea ing Qiland adapted to lie threaded on the outside of the shell ll'z .-l| ,u,li l r formed on the insulating lanlvl' l all'ords a stop \Ylllt'll position the easing 23'', on the shell. 1n atljn tell position tll. lower end .to prevent the easing from barking oil and obviously no other means than the threaded engagement between the parts i retpiirerl, to secure the easing in position on the sorket.

1 claim as my invention:

1. A candle socket, comprising an insulating: body lamp terminals mounted at one end thereol',-means mounted at the opposite end thereof for securing the sot-hot to a wire eondnih wire terminals electrically connected to the lamp terminals and having bind ing sen-'5 arranged at substantially right angles to the longitudinal axis of the. socket. an insulating easing: carried by one of the lamp terminals and snrroinu'iing both the lamp terminals and the wire terminals.

A randle surkel. mmprising an insulating: lHlll srrew Hlltll-Zllhl rent r mutant lamp terminals motmteal a one end thereof means mounted at the opposite end thereof (or securing the socket to a wire conduit, wire terminals electrically -eonneeted to the lamp terminals and having binding screws a rrangedat substantially right angles to thelongitndinal axis of the soel-zet, an 1nsu1ating casing having a threaded area screwed upon the screw shell lamp contact and surrounding both' the lamp terminals and the wire terminals.

3.. A candelabrum socket comprising an insulating body, wire terminals and a lamp socket screw-shell side contact mounted thereon, an insulating casing threaded on said shell and inelosing said wire terminals and abutting against said body at one end.

al. An electric lamp socket, comprising an insulating'body with a peripheral shoulder, wire terminals and a screw shell lamp-receiving contact mounted on said body to one side of said shoulder, in combination with an insulating casing earriedby said screw shell and inclosing said wire terminals, said caslag abutting at one end against said shoulder on the insulating body.

An electric lamp socket. comprising an insulating body with a peripheral shoulder, 7

wire terminals and screw shell lamp-receiving contact mounted on said body to one side of said shoulder, in combinatlon with an insulating casing havinga threaded area externally screwed uponv said screw shell and inelo'sing the wire terminals, said casing abuttin at one end against said shoulder on the insu ating body.

6. In a candle socket, an insulating body, screw shell and center contact lamp terminals mounted at one e'nd of said body, means at the other end of said body for mounting the same on a support, a peripheral ledge on the side of said body. wire terminals thereo and grooves cutting said edge and leading to' said wire terminals. in combinationwith an insuhlting casing seated against said ledge anl inclosing the lamp terminals and in part t e wire grooves.
