To all IIF/H/HP it I/hilg mace/"n:

lie it known that l, lVAL'inn R. Hanks, a citizen of the United States, residing at (hicago, in the county of Cook and State of Illinois, have invented an improvement in Supports for lncandesccnt-l llectric-Lamp Sockets, of which the following is a specification.

My invention relates to supports for the sockets of incandescent electric lamps, particularly to that class of lighting fixtures for producing the so-called semi-indirect lighting etiects, in which a transparent or translucent bowl is suspended, and the lead wiresare brought to one or more lamp sockets fixed within the bowl. in fixtures of this character it is customary to employ hangers to support the bowl, and to connect the supporting arm or bracket for the lamp sockets to such hangers or hooks. In all such cases of which I am aware the supporting arms for the lamp sockets have no adjustability and the lamps must remainin a fixed position relatively to the bowl.

The object of my present invention is to so construct the supporting arms for the lamp sockets, that the position of the lamps may be changed at pleasure and fixed in any clesired adjusted position within the bowl.

The details of the invention are hereinafter particularly described.

In the accou'ipanying drawing: Figure l is an elevation partially in section, illustrating my invention connectedv to a hanger at taohed to a bowl. Fig. 9 is a similar view showing the same attached to a modified for-In of hanger. Fig. 8 is a plan view of my improved support detached. Fig. l is an inverted plan view of thesame. l ig. 5 is av plan view illustrating the blank from which one mcmber formed, and l ig. 6 is a similar view, of the other incmber.

Similar reference characters indicate like parts throughout the several views.

1 designates a bowl of glass or other transparent material such as used in a fixture for producing a semi-indirect lighting of i ect.

2 designates av hai'iger connected with the l have represented the hanger provided with a hug 3, passed through a. hole in the bowl beneath its rim, said lug ha ring a reduced end screw threaded to receive a. nut 4. The hzniger also has a hook 5 at its upper end adapted end link of a supporting made of any suitable material. '1 also p11,-

ferto make each member of a, single'piece of metal cut out of the shape shown in Figs. 5 and (3. ihe men'iber 7 being bent to shape on the dotted lines 9, 10, ll, 32 and 13, and the member 8 on the dotted linell. lhe member 7 is provided with a central longitudinal slot 15 enlarged at one end. When the right angled projections at one end of the blank shown in Fig. 5 are bent to shape, they form the guide clip lei sh wn in Figs. 1,2, 3 and l, The opposite end of this member 7 provided with a circular opening 17. The member 8 is also provided one end with a similar opening "l8, while its opposite end is preferably somewha reduced in vidth and mfovidcd' with a Sti'CW-illl'filvdld hole 19, of smaller din'iension. This end of the member 8 is adapted to be inserted in the guide clip 16, on the member 7, when the set screw Eli) is gt and through the enlarged end (it the slot la in the member 7 and screwed into the small screw--threaded hole 19, in the member 8, thus connecting the. two members together in such manner that the member 7 is Slitlillllt. longitudinally upon the upper surface or the member 8. the screw E30 Workin in the slot l5 with its head in contact with the upper surface of said member 7. it will be apparent that the member 4" may be fixed at any desired longitudinally adjusted position upon the member by tight cninp; the set screw 20.

in connecting my improved socket support to a mg fixture. the opening 18 in the member 1 is placed over :1 lug); upon the hanger secured to the bowl. said lug having a 1'ETWV'hlllYililQd projection to receive a suitable nut to clamp the end of said memher is firmly between it and said in Fig. l or" the drawing in addition to the lug El and nut l, for securing the hanger 2 to the bowl 1. i have shown the hanger provided with another lup' 2i and nut-22 for altachn'ient oi" the member 3.

in l igz. of the drawing". i have shown the member 5% attached to the same/lug and secured by-thc same nut as employed For attin-hing the i anger to the bowl. As before remarked, the socket support may be attached to any charactertof hanger and in any suitable manner.

23 designates a hollow stud exteriorly screw-threaded on its lower part and secured within the opening 17 on one end of horizontal position. This may be done by- Zoosening the nut 22 or the nut 4 and swinging the support to the desired position and then tightenln the nut.

By the emp oyment of my invention, the same socket supports may beused upon fixit"ures of various sizes, as the length of the support can be varied to suit the circumstances, and allow-for proper relative arrangement of the lamps, and they can be secured in any desired adjusted position.

The end of the screw 20, after it has been screwed into the small screw-threaded hole 19 in the member 8, is preferably upset, which prevents possible loss of the screw, the enlarged end of the longitudinal slot 15, in the member 7, permitting the insertion or withdrawal of the screw-head at that point when it may be desired to connect or separate the two members; the reduced end of the member 8 also aiding in this respect.

1' claim as my invention:

1. A support for an electric lamp socket, comprising two members each cut out of a fiat strip of metal, one of said members 'having oppositely disposed right angled projections at one end bent over toward each other forming a guide clip, said member being provided with a central longitudinal slot enlarged at one end, a stud secured to the other end of said member for attach- 1 ment oi": a lamp socket, the other member havinga reduced portion at one end, with a screw-threaded hole therein, a headed screw secured within. said hole and adapted to be passed through the enlargement at the end of the longitudinal slot in said first member and passed along in said slot whereby the two members are held by means of said screw-head and said clip in slidable contact, the free end of said second member being provided with an opening for connection central longitudinal slot enlarged at one end, a stud secured to the other end of said member for attachment of a lamp socket, the other member having a reduced portion at one end with a screw-threaded hole therein, a headed screw secured within said hole and adapted to be passed through the enlargement at the end of the longitudinal slot inv said first member and passed along in said slot whereby the two members are held by means of said screw-head and said clip in slidable contact, the free end of said second member being provided with an opening for connection with said hanger.

3. A support for an electric lamp socket, comprising two members, one of said members being provided with a guide-clip and longitudinal Slot having an enlargement at one end, a stud secured to one end of said member for the attachment of a lamp socket, the other member having a reduced portion at one end provided with a screw-threaded hole and passed through said guide-clip on the first member, a set screw passing through said slot in said first member and screwed into said screw-threaded hole in the second member with its end'upset to pre Vent its withdrawal, the other end of said second member being provided with an opening for connection with a hanger.

Signed by me this 1st day of May, 1914.
