To all whom it may concerns 7 i e Be it known that I, THOMAS E. MURRAY, a ClllZGIl'Of the United States,-residing at New York, in. the county of New York and State of New York, have invented a certain new and useful Improvement in Sockets for Electric Glow-Lamps, of which the following is a specification;
; The invention relates to sockets for electric glow-lamps.
tion of said socket between anend thereof and the cavity therein openings for the re ception of circuit wires, whereby said socket and lamp may be supportedupon 'said wires;
in providing means for clamping and -lock-f ing said wires in said openings-so thatsaid wires cannot bewithdrawn or the-socket moved upon said wires; in constructingsaid means so as tobe operable only from within the- SOCkBt'CElVltY, and so that access cannot be had to the contacts of said means with said circuitwires, incombijning said means withthe terminals in the socketso that said terminals are secured also by said locking:
and clamping means, and in the construction more particularly. peinted out in the claims.
; In the accompanying drawings-Figure 1.

The socket 1 is cup-shaped and-preferably made integrally ofporcelain or-other insu- Extending transversely through the solid ortion of the socket'between the end thereo andthe cav- 'ity therein are two openings 2, 3,;through which; are passed the clrcuit wires 4:, 5. which are inclosed with any-suitable'insulating coverings 6." Said openings, as shown "cross section, haveaone side'arched to. con

' tween said flat sides and the'wiresj Within the socket is placed the internally threaded metal sleeve 9 for the reception of the plug of the glow-lamp. At the inner-end of said sleeve is an arc-shaped flange 10 which bears against the bottomof the socket. Said sleeve 7 is cutaway, as shown 'in Fig. 2, to receive a transverse rib or partition 11, integrally formed on the socket bottom, and also a bent contact- \plate'12 which is secured by two screws, 13, 14:, which pass into the opening 2 and through the spacing plate 7 therein; The screw 13, Fig. 6, has a 'flat end and is made suficiently long to force itself, when set up, through the insulating covering of the circuit wire 6. and into electrical contact with the wire itselfa The screw 14 meets.
contact caused between the flat end of the screw and wire, but by reason of the bending i up of the wire, the compression of the insulation,above the bend, against the arch of the opening and-the positive engagement of the screwbody with the insulation, below the bend, it: becomes impossible to withdraw the .wire'fr'om the opening or in any other way to obtain access to the exposed wireat the.
placefot electrical connection therewith. The arc-shaped flange 10 on-the sleeve is secured by two screws, 15 and 16, similar to screws 13, 14, which pass into the-opening and connect with the other circuit conductor in'the same manner already described with-.rcspect to screws '13- and 14. Theinnerportion or free endof the plate 12- extends' over. the rib 7 ll'whichforms a support for said freecnd, and which-may be enlarged as shown a't17 in Fig. 5, so as to form a broadbearing surface, if desired." Theplate 12, as shown, is supported wholly out of contact with the sleevefi and is designed to establish electrical connectionwith-the usual fixed central conplug of the glowtact plate'or'button on the lamp. y.
Y'Among the special advantages flowing from this construction are: When tlier'glowlamp isinserted in the socket, access to the terminals formed .by the sleeve 9 andplate I 12is completely"prevented. It is also im-v possible'foraccess to be had to the electrical -connections'between the circuit wires and said terminals, inasmuch as they are wholly 5 inclosed inthe material of the socket. The e socket and associate lamp-may he snpported solely on the circuit wires whlch pass through and are locked in the-openings .v This is especially 'important'when it isde'' sired to runteinporary lines, *asffor illuminations ofexhibit-ions and other displays,
electrical connections in the-socket, as; here 7 provided, "is of' economical importance. "Making the socket integrally of a single piece of porcelain or ,the' hke, effectually" protects the" connections; from. the. weather,
which is also important where the lines are exposed, as is oftenthe case withtemporary 'dis'pla'y arrangements; 1 The. flat--f ended screws used for establishing connection with the actual wires,- avoid the necessity of any such a screw readily reams outits own open-f ing in all ordinary insulatingcoverin ,;fits' tight jandfestablishes aflcontactfof s cient' area not to burn. out or become-easily'oxk dized.

1. As .a new article of manufacture and sale, a g1ow lamp socket, cup-shaped, iormed integrally of a single piece of reiractory esepa's insulating material and having in its solid portion -b'etweenone end and thesocket cavity, openings for the reception of supporting.-

3. A glow-lamp 'socket, cup-shaped, hav I ing a transverse opening extending-through 'the {solid portion between thee nd of the socket and the-cavity: therein 'for the rccep-.
