LIGHT-SUPPORT.

Specification of Letters Patent.

Patented Feb. 3, 1914.

Application filed May 9, 1913. Serial No. 766,566.

To all whom it may concern Be it known that I, WILLIAM E. DONNER, a citizen of the United States, residing at Grand Island, in the county of Hall and State of Nebraska, have invented certain new and useful Improvements in Light-Supports, of which the following is a specification.

The supporting device which is the subject of the present invention is. designed for use in connection with electric lamps employed for street! lighting, and the object of the invention is to provide a supporting device which allows the lamp to hang plumb at all times without the use of brace wires, and which is not affected by the current wires.

The invention also has for its object to provide a support which is strong and durable, and which can be easily and quickly installed.

These objects are attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a plan view of the device; Fig. 2 is an elevation thereof; Fig. 3 is an end view of the clamp whereby the device is secured to the overhead supporting cable; Fig. 4 is an end view of a modified form of clamp; Fig. 5 is a vertical section of the insulator to which the lamp-hood is attached, and Fig. 6 is a view similar to the last preceding taken at a right angle thereto.

In the drawing, 10 denotes an electric lamp provided with a hood and reflector 11 as usual. The lamp is an ordinary one such as is used for street lighting, and it is suspended from an overhead cable 12. On the cable is mounted a two-part clamp, the two parts being indicated at 13 and 14, respectively, between which parts the cable is placed. By means of bolts 15 passing through the clamp, and tightened up by nuts 15, the clamp may be fastened at any place along the cable, so as to locate the lamp wherever desired. To the base of the clamp part 13 is secured a cross-arm 16 carrying insulators 17 at its ends, around which latter the current wires 18 are wrapped, and

thence carried to the lamp, in a mannerto be presently described. The arm 16 projects equal distances from opposite sides of the clamp, and midway between its ends, on its under side, it carries a loop or ring 19, which latter passes through an eye 20 fitted to an insulator 21. This insulator is a substantially conical body having a rounded top in which the eye 20 is suitably secured. The body has a central passage 22 extending upward from the base thereof to a transverse passage 23 opening through the side of the body. In the passage 22 is secured a short tubular member 24 which depends from the base of the body, and has its projecting portion screw-threaded to receive nuts 25. This projecting portion of the member 24 extends through a central opening in the top of the hood l1, and by means of the nuts 25, the hood is clamped between the latter and the base of the insulator body. The wires 18 pass from the insulators 17 t0 the insulator 21, and are carried through the passages 22 and 23, and through the hollow of the member 24, to the lamp, to which latter they are connected in any suitable manner.

In the modified form of cable clamp shown in Fig. 4, the cross-arm 16 is at the top thereof. The clamp comprises two members 26 and 27, respectively, drawn together by bolts 28. The member 26 has a bottom hook 29 on which the insulator body 21 is hung.

It will be noted that the hood and the lamp carried thereby are loosely suspended, which allows the same to hang plumb at all times, and the suspension is not affected by the wires 18; nor are brace wires needed to keep the lamp plumb.

The construction is strong and rigid, and the device can be easily and quickly installed.

I claim:

An electric light support comprising opposite clamping jaws, an arm carried by one of the jaws, and having insulators on its ends, an insulating member suspended from the arm intermediate the ends thereof, and having passages for the current wires, and a lamp-supporting hood carried by the insulating member.

In testimony whereof I affix my signature in presence of two witnesses.

, WILLIAM E. DONNER.
