WILLIAM WHEELER, OF CONCORD, MASSACHUSETTS, ASSIGNOR TO THE WHEELER REFLECTOR COMPANY, OF BOSTON, MASSACHUSETTS.

ELECTRIC-LIGHT REFLECTOR AND ITS SUPPORT.

SPECIFICATION forming part of Letters Patent No. 254,523, dated March '7, 1882.

Application filed December 8,1881. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM WHEELER, of Concord, of the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Electric-Light Reflectors and their Supports or Attachments; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 denotes a side elevation, and Fig. 2 a top view, of a compound reflector provided with my invention, the nature of which is defined in the claims hereinafter presented. Fig. 3 is an inner end view of one of the reflectorsections with its clamps and binge portions, to be described. Fig. 4 is an inner end view of the other reflector-section, showing its hinge portions.

The reflector shown is of double formthat is, it is composed of two separate truncated or bonnet-shaped reflecting-sections, A B, arranged with their lesser ends or bases in contact. They are designed to reflectin opposite directions. rays or beams of light from an elec' tric burner arranged at or about at the center of their common intersection. There project from each of the sections, atits inner end, two ears, a a b b. These ears are provided with two sets of bin ge-j oint tubes, 00 d d d d, those marked 0 being projected from the ears of one of the sections, while those marked d extend from the ears of the other section. Each ot'the tubes 0 is to go directly between and in line with two of the tubes d, and with such and a pin, 0, passing through the three tubes, is to constitute a hinge.

Each ear of the section A has a clamp, O, hinged to it at its outer edge, such clamp and ear being recessed to receive and span a cylindrical insulator, D, of india-rnbber or other suitable material, through which tube one of the two vertical rods forming a part of. the frames of the electric lamp, and used in this case for supporting the reflector also, is to pass. Each clampC is furnishedwith a screw, E, which goes through it and screws into the ear,

and is to set the clamp firmly to the insulating-tube, and that to the rod. 7

Each reflector-section is notched at its lesser end, as shown atf, in order that when the two sections abut against each other at their lesser ends there may be a vertical passage through them to receive the carbon pencils or means employed in the reflector for generating the electric light. On withdrawing either of the hinge-pins from its tubes the section B may be turned on the other pin in a direction away from the section A, in order for access to be had to the burner or parts composing it, the two sections being fastened together when the two pins are in place in the hinge-tubes.

In certain cases where the lightis to be projected in one direction only, or when a double form of reflector, made in one entire part, is to be used, only one ear is provided upon each side of the reflector, and hence the hingesjoining the two separable parts herein shown are dispensed with,the clamps remaining as shown and described.

'I would remark that the two sections, instead of being provided with two hinges to enablethem to be opened apart in either of two directions, may be hinged together so as to open apart in one direction only; but I prefer to have them doublehinged, as described and represented, for in such case either hinge, be-

sides serving the purpose of a hinge, answers WM. WHEELER.
