WOLFE COMPANY, A CORPORATION OF NEW YORK.
12) all whom it may concern:
Be it known that I, FREDERICK L. ELLIS, citizen of the United States, residing at of Hartford and State of Connecticut, have invented certain new and useful Improvements in Electric- Light'Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as w1 ll en-- able others skilled in the art to which itapthe same. My invention relates to an improvementin electric light brackets.
Referring to the drawings wherein the several figures and letters of reference indicate like parts throughout the several views: Figure 1 is an-elevation' of the bracket, and broken view of the cord; Fig. 2 is an open jointed view of the bracket; Fig. 3 is a sectional view of the first section of the bracket showing the spring for taking up the slack in the cord, and broken sectional view of the base of the bracket; Fig. 4 is a detail plan view of one of the metal joints; and Fig. 5 is a broken view of the arms and cord showing the manner of connecting the arms to the sleeve joints. I
1 is the base, 2 a tubular section projecting therefrom, 3 and 4 the arms, and 5 is the lamp socket. As the sleeve joints are alike, they will be indicated by the same figure'of reference. These joints are first blanked out as shown at Fig. 4, comprising the skirt 6 and ears 7 having holes 8 t-herethrough for the pin 9 carrying the cord pulley 10, as shown at Fig. 5. The skirt of the blank is bent to form the tubular sleeve 6, having the open joint a. Said sleeve is made a trifle smaller than the end of the arm so as to exert a working friction between the sleeve and arm, which is made possible by means of the open joint.
The vertical section 2 has the reduced upper end 2 to receive the sleeve of the first joint, and also to form a kicking post for the upper end of the take up spring 10. The lower end of the spring is supported on the collar 11 adjustably secured to the cord conductor 12. The upper end of the cord being, of course, attached to the lamp socket 5. When, therefore, the arms of the bracket are Specification of Letters Patent. Application filed November -13, 1911.

deflected, as shown at Fig. 2, the strain on thecord will compress the spring and allow the deflected arms to draw up cord sufficient to compensate for such deflection, and the compressed spring will take up all slack that would otherwise occur in the cord when the joints are being closed, as without this take up feature the slack of the cord would be caught in the joints and not only tend toinjure the cord, but would prevent the joints closing.
As the ends of the arms are frictionally connected with the sleeve portion of the joints, it will be readily understood that the arms can be rotated in said sleeves -so that the bracket can be made to assume any position desired. The ears of the joints interlock, as'shown, and the side frictional tension on said cars is regulated by the nuts 13.
Having thus described my invention, what I claim is:
1. In an electrical lamp bracket, a base, a tubular section projecting therefrom, tubular jointed arms carrying a lamp socket connected with and extending from the tubular section, a retractile spring located within said section, a cord conductor connected with the lamp socket' and projecting through the arms and spring, an adjustable support on the cord for the spring, so that, when the arms are deflected, power is stored up in the spring to be automatically utilized in taking up the slack in the cord.
2. In an electrical lamp bracket, a base, a tubular section connected therewith having a reduced upper portion, tubular arm sections, open jointed pivotal connections for the arms and tubular section, a retractile spring within said section abutting against said upper reduced portion, a cord conductor connected with the lamp socket and projecting through thearms and spring, and an adjustable spring support secured to the cord for the purpose set forth.
In testimony whereof I affix my signature in presence of two Witnesses.
