the composition of illuminating-tiles may be spread, thereby imparting
unusual strength to the plate and causing the plastic material to set
in such a way as will secure it a firm hold on the plate and the glasses
E' represents plain unbroken flanges that may be used sometimes in place of the ribs E. Like these they project outwardly from both sides of the tile-plate, and they completely surround the light-openings and part of the lens or lenses filling or covering the same. They may be either round or quadrangular in shape, as preferred.
F is the filling material which I use in connection with the plate and the lenses. This, in ordinary cases, may be concrete or cement, but where a fire-proof construction is desirable I prefer the use of plaster of paris, at least on one side of the tile, as at F', Figs. 7 and 8. Whichever filling is used, it is carefully packed in and around the ribs or flanges of the plate between the light-openings and brought up to a level with the outer surfaces of the glass and the ends of the plate on both sides. Thus is formed an illuminating-tile in which the border of the plate, the filling, and the lenses are all in line or on a level on both sides, thereby presenting a neatness of appearance and affording material advantages that are not found in other constructions.
Figs. 7 and 8 illustrate a practical way of setting up my improved tile in place, which consists in providing it with pivot pins G that allow it to swing within an outer frame or casing H located at any suitable point in a partition or wall I where illuminating-tiles are employed. The frame H and the tile therein may be of any convenient shape, but it is thought the octagonal form shown in the drawings will be found generally acceptable. Flanges h h' inwardly projecting from opposite sides of the frame afford bearing points upon which the edges of the tile may rest and prevent it from being swung around indiscriminately.
The tile may be fastened and practically locked from the inside by means
of a thumb-screw J passing through small plates K K' secured one to the
edge of the tile and the other to the edge of the casing. Tiles mounted
and arranged in this way may be used with as much advantage in sidewalks
as in the partitions or walls of a building. They are invaluable for
ventilating purposes and afford besides an important and ready means of
escape in a case of fire.|
Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is--
1. An illuminating-tile consisting of a perforated plate provided with flanges on both sides, oppositely-placed lenses covering the openings in said plate on each side and having their outer faces in line with the outer edges of said flanges, and filling between said lenses forming even surfaces on both sides of the tile, substantially as set forth.
2. An illuminating-tile composed of a plate provided with light-openings, lenses therein, and a series of forked ribs disconnected at the forked ends forming cavities in said plate, and filling material, substantially as set forth.
3. An illuminating-tile comprising a plate provided with light-openings, curved ribs having forked ends concentrical with said openings, lenses, and filling, substantially as set forth.
4. An illuminating-tile consisting of a perforated plate, oppositely-placed lenses covering the openings in said plate, a series of internal flanges or ribs surrounding said lenses, and filling material covering said flanges or ribs on both sides of the plate, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
