ELECTRlC LAMP FRAME.

SPECIFICATION forming part of Letters Patent No. 359,916, dated March 22, 188'? Application filed September 15, 1886. Serial No. 213,658. (No model.)

.To all whom it may concern.-

Be it known that I, THOMAS H. BRADY, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Electric-Lamp Frames, of which the following is a specification.

My invention relates to improvements in frames for hanging electric lamps of the class in which a hood and lamp are supported by means of standards at the top of a pole; and the objects of my invention are to simplify the construction and to so secure the line-wires that they will not become detached upon the breaking of an insulator.

In the accompanying drawings, Figure 1 is a side elevation of my lamp. Fig. 2 is a central vertical section of a portion thereof throu gh one of the standards and insulators; and Fig. 3 is a horizontal section of said standard and insulators on line a m of Fig. 1, the line-Wires and cap-iron being shown in plan view.

A designates the upper end of the pole or post to which the cap-iron Bis secured. The cross-arms extend laterally each way from the socket of this cap and have-at their outer ends or terminations the bosses a a, which are bored vertically to receive the lower end of the standards 6 b, by means of which standards the hood 0 and thelamp D are supported. I thread the lower ends of these standards for some distance, as shown in Fig. 2, for the reception of the nuts 0, d, and e. I form the insulators E of the ordinary form externally, but with a hole entirely through them, the main portion of which is of a size to receive loosely the lower ends of said standards I), while the lower end of this hole is large enough to receive the nut d.

In putting the parts together the not 0 is first placed upon the standards Z), then the insulator E is slipped thereon, and the nut d is screwed on to hold the insulator in place, tak-' ing care, however, not to confine the insulator too closely. The standards with an insulator on each are then passed through the bosses at a of the cap-iron arms and secured firmly therein by the not a. After the lamp-frame is placed in position on the top of the pole or post the line-wires f are passed between the upright standards I) b and made fast to the insulators by means of the ties 9. These linewires are connect-ed with the lamp in any ordinary manner.

By my improvements the lamp-frame is less bulky than heretofore, much more simple and economical in construction, and in case one or both of the insulators should he accidentally broken the linewires will still be held within the lampfra'me, so they cannot fall down to the ground or below the top of the pole.

Heretofore in this class of lamps the insulators have been attached upon arms which are tend laterally each side of the standards by means of a wooden pin or plug held in these extensions, the insulators having a socket or hole partially through them and supported upon the upper end of the wooden pins. Such a lamp-frame is hereby disclaimed.

I claim as my invention- The herein described frame for electric lamps, consisting of the cap-iron B, having lateral arms which terminate in the bosses a a, the standards I) I), secured within said bosses, and the insulators E, surrounding the lower ends of said standards above said bosses, substantially as described, and for the purpose specified.
