IMPROVEMENT IN REFLECTING LAMP-SHADES.

Specification formingpart of Letters Patent No. 149,386, dated April 7, 1874; application filed March 17, 1874.

To all whom it may concern:

Be it known that I, DE GRAssE FOX, of Philadelphia, Pennsylvania, have invented an Improvement in Lamp-Shades, of which the following is aspecification:

My invention is applicable to lamp and gas-light shades of porcelain, glass, or other transparent or translucent material. My invention consists in combining with an exterior transparent or translucent shade an interior opaque reflecting-shade formed in leaves or sections, arranged so that said sections can be opened or'closed more or less, and the light thfps regulated as required.

In the drawings, Figure l is an inverted plan of a shade embodying my improvement. Fig. 2 is a vertical cross-section of the same.

a represents an ordinary glass shade. b are separate leaves or sections of burnished metal or other incombustible reflecting material, each of said sections being rigidly attached to a wire forming a bent lever, c. The several sections 11 pass through tubes d respectively, said tubes being rigidly attached to a supporting-band, e, which is attached to the body of the shade a, so that said band shall not move. Each of the levers 0 contains an eye, f. g is a ring or band movably attached to the top of the shade a. h are wires rigidly attached to the ring 9 and united by hooks,

which pass through the eyes f respectively, thereby forming a flexible joint between the wire I) and the levers c. i is a knob or handle for turning the ring 9, and, through the action of the wires 71. and levers c, adjusting the several reflectors b so that they can be completely closed upon the shade a, or opened more or less, as desired.

I claim- 1. The combination of an exterior transparent or translucent lamp 'or gas-light shade, and an interior reflector composed of separate sections of opaque reflecting material, with means for turning or adjusting said sections, all for the purpose of controlling the light by allowing it either to pass through the exterior shade, or causing it to be wholly or partially intercepted and reflected by the interior sectional reflector, as required, sub stantially as set forth.

2. The combination of the reflectors b, bent levers c, and tubes d, with means for the rigid support of these tubes, and also with means for opening and closing said reflectors, substantially as and for the purpose set forth.

DE Gr. FOX.
