From what has already been said and from this brief description of the drawings, which are intended not to show all possible applications of my invention, but simply to suggest the manner in which it may be utilized, it will be evident that any desired design may be produced by the application of the principle which I have employed.     I do not wish to be limited to the particular quality or character of the glass or glass-like substance used, nor to the particular form or fashion of the prism, nor to the particular designs employed.     The prisms may be inside or out, or on both sides, the glass may be colored, and any desired design employed. I prefer, however, the employment of light-transmitting prismatic glass arranged so as on the whole to increase the volume of light usefully introduced into the room.     Of course my invention is intended to be applied to practically flat glass bodies, such as are used for windows, and the prisms employed are intended to be substantially flat-surfaced prisms, which will be substantially all of them arranged so that they will cooperate to reflect or refract the light, so as to increase the illumination of the room, and such prisms I call "useful" prisms as distinguished from mere irregularities or roughened or broken surfaces of the glass, which are not

intended and do not have the power of increasing the illumination of the room. The complete window-light is called a prism-plate, and the several sections are called "prism-lights."     I claim—     1. A prism-plate for windows comprising a series of prism-lights united together to form the plate, the prism-lights arranged in groups so as to form a predetermined design or figure, and the prisms of the prism-lights forming such design or figure inclined or tilted with reference to the prisms of the prism-lights surrounding the same, substantially as and for the purpose specified.     2. A prism-plate for a window having a receiving-surface and a series of projecting prisms systematically arranged to produce an increased illuminating effect for the apartment on the other surface, certain prisms arranged in groups to form a predetermined design, the prisms of the group which forms the design varied with reference to the surrounding prisms so as to throw the light in a different direction and thus exhibit the design.
