SKYLIGHT.
SPECIFICATION forming part of Letters Patent No. 586,250, dated July 13, 189'7.
` Application filed March 8, 1897. Serial No. 626,424. (No model.)
of a light-diffusing device embodying my ini vention.
I have illustrated in the drawing a device particularly adapted for skylights and the like, and which is so constructed that the vertical rays of light are projected in a cerzo tain definite direction, and the rays of light from some other direction are also projected in a direction substantially parallel to the vertical rays.
I have shown a series of prisms A, having the plane surface B and having the prismsurface C'. The two surfaces are so positioned with relation to each other that the vertical light and light from some other direction on passing therethrough are projected 3o in substantially parallel lines toward some given point. The ray of light D, for example, enters the prism and is refracted out through the surface C, by which it is again refracted so as to leave such surface in a substantially vertical direction. The ray of light E enters the prism A and strikes the surface B at such an angle as to be reflected by such surface. The ray passes out through the surface C and is refracted so as to be projected in a direction substantially parallel to the ray D.
The side C of the secondary prism is parallel with the smooth side B of the prism, as indicated in the drawing, Whereas the short side of the secondary prism in question is substantially parallel with the receiving side of the body of the prism proper.
I claim- As a new article of manufacture, a prismlight for skylights or the like, comprising a body of glass with a receiving-surface on one side and a prism-surface on the other side, said prism-surface consisting of a series of projecting prisms having each one plane surface and one prism-surface, such last-named prism-surface made of a series of prisms having each one surface parallel with the receiving-surface, and the other surface inclined to the receiving-surface and parallel with the plane surface of the prism.
