I. G. SOPBR.
BASEMENT LIGHT.
Patented July 13,1897.
jli ar/ Lag UNITED STATES PATENT OFFICE.
FRANK C. SOPER,
BASEM ENT-LIG HT.
SPECIFICATION forming part of Letters Patent No. 586,252, dated July 13, 1897.
Application filed April 20, 1897. Serial No. 632,969. (No model.)
To (tZZ whom it may concern:
Be it known that I, FRANK C. SOPER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,
have invented certain new and useful I111- provem cuts in Basement-Lights, of which the following is a specification.
My invention relates to a device for lighting basements and the like, and has for its IO object to provide a new and improved device for this purpose, of which the following is a description.
My invention is illustrated in the accompanying drawings, wherein I5 Figure 1 is a view of a basement, showing one form of my device. Fig. 2 shows a modiiication.
Like letters refer to like parts throughout both figures.
A is the basement or room to be lighted; B, the vault beneath the pavement, which is composed of the tile-sections C and D, faced in opposite directions and adapted, both of them, to throw the light upon the prism-plate 2 5 E, which is preferably composed of a series of pris1n-lights united by electroglazing.
F F are prisms which throw the light in some other direction. Of course the size, form, )roportion, and arrangement of the sev- 0 eral parts may be greatly varied without departing from the spirit of myinvention. The
. angles of the prisms in the tiles and also of the prisms in the plates will be varied, and the angle of inclination of the plate may be 5 varied to suit varying conditions. The device is applicable to the illumination of rooms, whether basements or otherwise. The tiles are made up into a so-called pavement, though of course this pavement is nothing 0 more than a pavement-like construct-ion projecting substantially horizontally from the building.
I have illustrated my device as applicable to basements, but it is evident that it will be 4.5 applicable to other situations where illuminating eifects are to be produced.
I claim- 1. A device for lighting basements and the like comprising a series of prism-tiles arranged in oppositely-facing sections, in combination with a transparent prism-plate, depending beneath and between such sections.
2. A device for lighting basements and the like comprising a series of prism-tiles arranged in sections, oppositely faced, in combination with a prism-plate having a comparatively smooth surface on one side with a prismsurface on the other side, the several prisms set at an angle so that the light will be thrown from the one section of the prism-tiles upon the prism-surface of the plate and be thence reflected into the direction desired, while light from the other section of tiles will be thrown upon the smooth surface of the plate and will be transmitted therethrough and be refracted thereby so as to be directed into the room to be illuminated.
3. A device for lighting basements comprising two sets or sections of prism-tiles, a re ceiving prism-plate intermediate between said two sets or sections and suspended in a substantially vertical plane, said prism-plate so formed as to refract the light received from one set of prism-tiles and direct it into the basement and reflect the light from the other set of tiles and also direct it into the basement.
i. A device for lighting basements and the like, comprising a transparent pavementlike body projecting substantially horizontally from the building and provided with two sets of prism-tiles adapted to throw the light in opposite directions, a substantially verticallyarranged transparent prism -plate, so suspended between the two sections that light 8 from one section of tiles passes through the prism-plate and is refracted into substantially horizontal lines, while the light from the other section of tiles is reflected from the prism-plate into substantially horizontal 0 lines.
