' www UNITED STATES EDWARD WESTON, OF NEWARK, NEW JERSEY, ASSIGNOR TO THE UNITED STATES ELECTRIC LIGHTING COMPANY, OF NEW YORK, N. Y.

BRACKET FOR INCANDESCENT LAMPS.

SPECIFICATION forming part of LettersPatent No. 263,828, dated September 5, 1882. Application filed February 18, 1882. (N o model.)

To all whom it may concern:

Beit known that -I, EDWARD WESTON, a subject of the Queen ot' Great Britain, and a resident of Newark, in the county ot' Essex and State of New Jersey, have invented certain new and useful Improvements in Brackets for Incandescent Lamps, of which the folllowing is a specification.

My present invention is directed to the construction ot' electric-lamp brackets, the object being to produce a jointed bracket or support for one or more incandescent lamps similar in appearance to the ordinary forms of lamp or.

gas brackets now in use, and arranged to contain the conducting-wires that convey the current to and from the lamp or the circuit-controlling devices connected therewith.

The invention consists in the arrangement of' conductors at the joint or joints iu said bracket, which prevents breaking or abrasion ot' the same when the bracket is turned, and the short-circuiting or interruption of the circuit, by which such accidents would be followed. In the drawings hereto annexed, Figure l represents in elevation and part section a bracket constructed according to my `invention; Fig. 2, an enlarged sectional View of the g joint.

The bracket is shown as consisting of an arm, E, attached to a tube, E, pivoted by insulated heads to contact-posts set in a plate, B. This latter is slotted and secured by bolts to an insulated plate, A, recessed for the reception ot' terminal contact-springs and a safety-wire, as fully explained in another application of even date herewith. The hollow arm F ends in a cylindrical chamber, G, which is closed below by a screw-head. This chamber terms a socket within which lits the secinterior of cylinder G.

Two plates of insulating substance, lc It, are secured near the opposite ends ot' the cylinder, and a Wooden pin, H, held between them. The conductors are brought from the firstjoint or tube under the plate h and are carried up through perforations therein. They are then formed in spirals about the pin H and carried through the upper plate, k. From this they are led into the second section, L, and connected to the terminals of a switch, N', by means ot' which the circuit is completed through the lamp M. By this arrangement the wires arel not attected by the movement ot' the sections of brackets, except in the spirals. As these permit ot' considerable movement without bringing the wires into contact with each other or subjecting them to any strain, no accidents from breaking or Wearing' oft' ot' the insulating material are likely to occur. As a further precaution the walls ofthe chamber G are insulated, sothat it' the convolutions ot' the spirals are forced into contact with them no injury can result. Arm L, Whether by a special construction or by means of suitable stops, should not be capable ot' a complete revolution in the socket G. A movement of three hundred and iifty degrees may be safely permitted without liability ot' twisting too much the conductors.

It may be stated that the number of joints or sections ot bracket is not material, though two will for most purposes be amply suflcient.

While I do not claim broadlyherein a jointed bracket for incandescent lamps, I do not wish to be understood as confining myselt1 to the precise arrangement described. The object in view, as appears from the description, is to keep the conductors, as far as practicable, inclosed in the bracket to prevent them from kinking and abrasion, and to secure a perfect electrical connection between the wires in one section ot' the bracket and those in the others.

. Instead of the conductors proper being carried through the plates h k and bent into the spirals, these latter may be formed independently and of some metal more resilient than copper, and the conductors joined to them.

Having thus described my invention,what

N is a tube ofinsulating material fitting the I claim is 1. The combination, with a jointed bracket or support for incandescent lamps, of conductors contained Within tnc bracket and formed in spirals at the joints, substantially as and for the purpose set forth.

2. The combination, in a bracket for incandescent lamps, of a section, as F, a section, as L,`and a joining-section, G, With conducting- Wires passing through the several sections and formed in spirals in the joining-section, substantially in the manner described.

3. The combination, in a bracket for incandescent lamps, of a section, as F, a section` as i L, ajoining-scction, as Gr, and insulating-plates 7c h, with conducting-Wires passing through said sections and the plates 7c 7i, and formed in spirals in the-section G, substantially as shown.

j 4. The combination of section F, section L, and insulated joining` section or socket Gr, with conductors passing through the said sections and formed in spirals in the insulated joiningsection, as shown. y

5. The combination, in a bracket for incandescent lamps, of a section, as F, a section, as L, a joining-section, and pin H with conductors passing through said sections and plates, and formed in spirals around the pin H, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand this lith day of February, 1882.
