Letters Patent No 96,336, dated. November 2, 1869.

IMPROVEMENT IN REFLECTORS.-

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, SAMUEL MEADOWS, of Toronto, in the Dominion of Canada, have invented a new and improved Reflector; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

The object of this invention is to provide a glass 7 reflector, having the glasses so arranged as to have greater power than those now in use, and so that por- 'tions of the reflecting parts may be adjusted to throw the light on any given point, and also so arranged, in respect to the frame for the support of the glass, that the same may be easily and cheaply put together and parts removed for the substitution ofother glasses when broken.

Figure 1, in the accompanying drawing, represents a top view of my improved reflector, and

Figure 2 represents a section of the same, taken on' the line at a: of fig. 1.

I make the frame A, which may be of any preferred form, square, pyramidal, sexagonal, octagonal, or according to the number of ad ustable reflecting-glasses to be used, of cast-metal sectional plates, with flanges (1, having recesses, and projections 1), arranged to fit or. look together, and hold the parts in position when connected by links 0, so that any one plate or section may be readily taken out.

These sectional plates support fixed corrugated mirror-reflector glasses B, and each -is provided with a large circular orifice, D, wherein concave mirror-reflectors E are adjustably supported on transverse rods F, spanning the orifices and supported in studs G, projecting from the exterior faces of the plates, one of the saidstuds for each glass being provided with a setscrew for holding therods. These reflectors Emay thus be adjusted to throw the light from one or more burners to various points in the room, and may be placed onany or every side or section of the frame.

The-corrugated fixed glasses B are plated in the same manner as mirrors, and covered with white enamel for protection, causing the light to be greatly refracted. These glasses are fastened in the sectional plates by plaster-of-Paris or other cement.

To further increase the power of this reflector, I suspend a reflector, G, similarly formed in its general features, except tha'tthe exterior surface constitutes the reflecting part, from the centre of the top, as shown bya rod, H, -having corrugated glass reflectingsurfaees, and small concave reflectors I, whereby thepower is greatly increased. Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- 1., The adjustable concave reflectors E, combined with the case A, having the corrugated reflectors B, and all arrangedsubstantially as specified.'

2. The combination, with the reflector A, of the inverted reflector G, the former being adapted to re-
