IMPROVEMENT IN LAMP-S'HADES.
Specification forming part of Letters Patent No. 48,532. dated J uly 4, 1865.
To all whom fit may concern Be it known that I, CORNELIUS S'r. JOHN,
I of Boston, in the countyof Suffolk and State of Massachusetts, have invented an Improved LampfShade; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- A Figure 1`den0tes' la `top viewfFig. '2 "'a'side elevation, and Fig. 3 a vertical section, of it.
In such drawings, A denotes an ordinary lamp-shade made in the form of the frustuxn ot'a. pyramid, and provided'with a supporter, B, extending down from .onesideot' it. The interior surfaces of each side of the said shade I line with a plate of mica, a, which not only 'serves as a lght-retlecting surface, but ns a v means of reflecting heat, and preventing combustion of the paper or material of which the body of the shade may be composed. To the .lower edge' of each face or side of the shade I hinge a reflector or reflecting-plate, C, which may be made of mica or glass, and with its surface or surfaces so treated as to render the deiiector semilucent, Or so that while its lower surface will answer to reflect light, more or less light may pass through' the reflector and be diffused from it-that is, when there may be a llame within the shade, or such shade may be surrounding a lamp-wick enamed.
With the shade A provided with the series of movable reflectors C the angles of reflection of the rays of light from the llame may be varied more or less, as circumstances may require. In this way the main part of the rays maybe thrown down or concentrated into a small space, or such light may be diffused over a larger area. more or less of the light will pass vthrough them, portions of it will be relected by them.
shade A and the'series of reilectors G C, &c., arranged and applied to it substantially as and so as to operate as specified.y
