ARTHUR J. BROWN, OF NORWOOD, OHIO.
Specification of Letters Patent.
Patented Tan. 5, 1909.
Application filed November 7, 1907. Serial No. 401,078.
To all whom it may concern:
Be it known that I, ARTHUR J. BROWN, a citizen of the United States, residing at Nor- Wood, in the county of Hamilton and State of Ohio, have invented certain new and use ful Improvements in Reflectors, of which the iollowmg is a full, clear, and exact specifica- My present invention relates to improvements in reflectors designed to be placed in proximity to and reflect the lightfrom electric lamps or other similar sources of illummation.
The main object of my invention is to produce from a relatively fixed source of light,
in an eflicient and simple manner and at will,
a diflused beam of light or a concentrated beam of llght made up of parallel rays and ca able of being directed as desired.
11 carrying out the object of my invention I employ a reflector built up of a plurality of parts relatively adjustable to permit the rays of light being projected in any desired direction and in any desired form.
The invention comprises certain novel details of construction described hereinafter and specifically pointed out in the appended claims.
In the accompanying drawings, which illustrate the preferred embodiments ofiny inventlon, Figure 1 is a perspective view of my improved reflector in position adjacent to an incandescent lamp; Figs. 2, 3 and 4 are end elevations of the device shown in Fig. 1, showing the reflector in diflerent ositions of adjustment; Fig. 5 is a detail p an view of one end of the reflector showing one way of maintaining the parts of the reflector in their adjusted positions; and Fig. 6 is a detail plan view, similar to Fig. 5, showing a modification.
Referring now to the figures of the drawmg, 10 indicates a sup ort for the socket 1 1 of the lam s 12. Attac ed to this support 10 1s a bloc 13 forming the middle member of my improved reflector. The under side of this block 13 is provided with a reflecting surface. d le member 13, and adjustable relative thereto, preferably by being attached by hinged joints 14, are the side reflector members 15 and 15. Each of these members 15 and 15 is made up of a plurality of rectangular shaped lates 16 having their inner surfaces polishe or coated with a highly reflectmg material. These plates are preferably Attached to the sides of this mid' long and narrow strips of sheetmetal. The plates are relatively adjustable, being hinged together at 14. The ends 17 of each plate are rolled back to improve the appearance of and to assist in stiflening the reflector. These rolled back or tubular edges may form housings for the retaining rods 18 formed of nonresilient material of such nature and strength that they can be bent into any desired sha e and will retain the members 15 and 15 in any form or ositioninto which it may be found desirab e to adjust them.
As a substitute for the rods 18, and to assist the friction of the hinged joints 14 in retaining the plates 16 in relatively adjusted position, the modification shown in Fig. 6 may beemployed. This consists in placing spring disk members 19 on the extended ends 20 of the hinge pintles 21between the nuts 22 on said intles and the ends of said plates 16.
It thus be seen that my improved reflector may assume any desired curvature de endent uponthe nature and direction of lig t distribution that is required.- Considering a pendent lamp support, such as is shown in the accom anying drawing, the reflector in Fig. 2 is a justed to produce a diffusion of the light rays, in Fig. 3 to concentrate said rays in a arallel' beam. directed downwardly, and in ig. 4, to concentrate said rays in a parallel beam directed at right an les to the support:
ertain modifications can be made without departing from the spirit and scope of mny invention and I aim in the claims to cover a such modifications. A
What I claim is 1. In combination, anelectric lamp support, a reflector carried by said su port, sald reflector com a plurality o relatively adjustable pl tes, and means for fastening said plates together to permit the formation of a reflecting surface of any desired curvature.
port, a reflector carried by said support, said reflector com rising a plurality of relatively adjustable liites, means for fastening said plates toget lier to permit the formation of a reflecting surface of any desired curvature, and means for retaining saidplates in their adjusted position.
3. In combination, a supporting member, a lamp carried thereby, and independently adjustable reflecting members hinged to said supporting member on opposite sides of said 2. In combination, an electric lamp suplamp, each reflecting member being made up of a plurality of long and narrow strips of sheet metal, and provided with means for fastening said strips together so that they may be movable relative to one another to of sheet metal hinged together to permit.
their being adjusted to approximate any desired curvature, and means for retaining said strips in their adjusted position.
5. In combination,asupportingmember, a reflecting member hinged to said supporting member, said reflecting member being made up of a plurality of long and narrow strips of sheet metal hinged together to permit their being adjusted to ap roximate any desired curvature, and rods 0 non-resilient material fastened to each of said. sheet metal strips for the purpose of retaining same in adjusted position.
6. In combination, a supporting member, two reflecting members hinged independently to said supporting member, each of said reflecting members being made up of aplurality of. long and narrow strips of sheet? metal hinged together to permit their being adjusted to approximate any desired curvature, and rods of non-resilient material fastened to each of said sheet metal strips for the purpose of retaining same in adjusted position. 7. In combination, a supporting member, a reflecting member hinged to said supporting member, said reflectin member b'e'ing made up of a plurality of on and narrow strips of sheet metal relative y hinged to permit their being adjusted'to approximate any desired curvature, and-means for assisting the hinged joints between said strips in holding same in any desired position.
- 8. In combination, a lamp support, a lamp carried thereby, and a reflector adjacent said lamp comprising members carried by said support on 0 posite sides of said lamp, each member 0 said reflector being formed of a plurality of relatively adjustable long and narrow plates having reflecting surfaces, said plates havin their long edges hinged together whereby t e rays from said lamp may be cast in any desired direction either as diffused rays or in a parallel beam by simply adjusting the relative positions of said lates.
9. n combination, a lamp support, a lamp carried thereby, a reflecter adjacent said lam and carried by said su port, said reflector eing formed of a lura lty of long and narrow plates having re ecting surfaces, each plate being hinged to the next adjacent plate whereby the rays from said lamp e cast in any desired direction eit er as diffused rays or in parallel beam by simply adjusting the relative positions of said plates,
and means for assisting the friction in said hinged joints in retaining the desired adjustment of said plates. 7
In testimony whereof I afiix my signature, in the presence of two witnesses.
