EDWARD WESTON, OE NEWARK, NEW JERSEY, ASSIGNOR To THE UNITED STATES ELECTRIC LIGHTING COMPANY, OE NEW YORK, N. Y.

BRACKET FOR ELECTRIC INCANDESCENT'LAIVIPS.

SPECIFICATION forming part of Letters Patent No. 277,642, dated May 15, 1883,

l Application filed November 25, 1882. (No model.)

To all whom it 'may concern Be it known that I, EDWARD WESTON, a subject of the Queen of Great Britain, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Brackets for Electric Lamps, ot' which the following isa specification, reference being had to the drawings accompanying and forming a part of 1o the same.

My present invention, which relates to im-' provements in the construction of the joints of brackets for supporting incandescent lamps or similar devices, is illustrated in the accompanying sheet oi' drawings, where- I Figure l is a view in elevation of aconpling or joint-constructed in accordance with my invention 5 Fig. 2, a plan view of the same; Fig. 3, a central verticalsection, and Fig. 4 a

zo horizontalsection on line x rv of Fig. 3.,

' In another applicationI have shown and described a bracketjoint in which two sets or pairs of conducting-rings concentric with the pivotal axis ofthejoint were the means Ofcomz 5 pleting the circuit between the two parts of .the joint or coupling. My present invention, while embracing this and other features elsewhere described by me, constitutes an improvement upon the forms of joint alluded to, theV 3o construction of the joint in the present case being such that one arm-ot' the bracket or section of the coupling to which the saine is joined is not limited in its movement, but may be turned in the same plane at any angle to 3 5 the other section.

Referring to the drawings for an understanding of the details of construction, the letters 'A B desig-nate the ends of the sections of an ordinary electric bracket or support. C D are Section, as B.

| its lower edge, are passed over the sleeve a and secured to its opposite ends. To these 5o rings insulated conducting-wires c d, passing from the section A through the base C and up through the pin E, are joined, so thattherings forni terminal contacts. The pai-t or section D is a cylindrical cup provided with means i'or readily attaching to it the end of a bracketlt is open at one. end, and contains an insulating shell or casing, c. Metal rings H K are secured to this shell by insulated screws h, and the ends of two conduct- 6o ors contained in the section B are joined to the rings H K, making good electrical contact therewith. rlhe cup-shaped section D, with its lining of insulating material and rings, should tit snugly over the inner or lower part of the 65 coupling, the rings H K registering with the ringsfg. Spaces that are left when the two parts of the joint are thus put together may be iilled in with a ring ot' insulating substance or not, as desired, and, inlieu of being made con- 7o tinuous, the cup D may have one or more openings or slots,j", as shown in Fig. l.

The operation or action of a joint thus formed is very simple and efficient. Intimate contact between the two Setsof rings is always maintained, even it' thejoints should by long usage 'become loose, as the weight ofthe outer arm,

as D, tends to tilt the cup D and press the diagonally-opposite portions of the two pairs of rings closer together.`

Further advantages of this device are that the-conductors. are entirely inclosed and not liable to derangement or injury, and that one section of the bracket may be turned completely around the pivotal axis.
