To all whom it may concern: Be it known that I, WILLIAM H. WINSLOW, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain Improvements in Processes of and Means for Framing Up Glass and other Tile, of which the following is a specification. My invention relates to methods for uniting or bringing together a series of tile, particularly glass tile, into a body, so as to make a window or covering for an aperture. My invention relates to and is applicable to various kinds of glass or tile, but I have particularly illustrated it in connection with prismatic window-glass and vault-lights, which is the particular field at present intended by me to be occupied by this invention so far as it relates thereto. Prismatic tile or the like commonly consists of glass bodies more or less smooth on one side and provided with inwardly or downwardly projecting ribs or the like on the opposite side. These ribs have faces set so that the rays of light entering will be refracted or reflected, as the case may be, by the inclined walls or faces or surfaces of said ribs. Referring to the particular kind of tile which is illustrated in the drawings, I would explain that these tiles consist each of a body of glass with a smooth outside surface and inwardly-projecting refracting-ribs, one face of each rib being nearly at right angles to the surface and the other being inclined thereto. In the preferred form of my device each tile or separate piece of glass has its ribs extending clear to the extremity of the tile in every direction so far as may be possible. The separate sections of glass are to be brought together firmly and held securely in position. This ought to be done with the least possible obstruction of light, or, in other words, the connecting devices which join the several sections of glass together should be as thin as possible. Again, in the case of prismatic glass the prismatic ribs or projecting parts should cover the greatest possible portion of the inner surface of the tile, for since these ribs tend to distribute the light any break between them, as for example, by means of ledges which surround the prismatic portion, will of course present a side surrounding or intervening strip which will not distribute the light. |
Again, the connection must be such as to make the completed body
waterproof and of a nature to resist the action of the atmospheric
air. Again, if the complete body of glass or tile is to be of any
considerable extent, and particularly if it is to be inclined or laid
horizontally, or if the tile are to be made of heavy weight, as in the
case of vault-lights, it is necessary to support the several sections
or the complete body through the middle. Again, it is highly important
that the ribs should be arranged in such manner as to make it easy for
the same to be cleaned and to leave as little as possible in the way of
corners and obstructions to prevent cleaning. In other words, it is
desirable to have each rib as nearly as possible continuous across the
whole width of the body when completed. All these results and many more
as well accomplished in my device, particularly when the same is applied
to such prismatic window and vault lights as are illustrated in the
accompanying drawings, wherein-- Figure 1 is a plan view of a series of prismatic window-lights laid in position on a table and in a frame. Fig. 2 is a cross-section on the line 2 2 of Fig. 1. Fig. 3 is the same as Fig. 2, with metal deposited between the tile and the strip. Fig. 4 is the same as Fig. 2, with metal deposited overhanging the surfaces of the sections. Fig. 5, 6, and 7 are detail cross-sections of modifications of connections. Fig. 8 is a plan view like Fig. 1, with the prismatic ribs extending entirely across the tile on which they are formed. Fig. 9 is an enlarged detail of a modification. Like parts are indicated by the same letter in all the figures. A A indicate the prismatic tiles. O is a metallic frame, which may or may not be the permanent frame for the complete body of glass, though it is perhaps preferable to have this frame in which the glass is formed into the body permanent therewith. B is a table on which the parts may be conveniently assembled. C C are the prismatic ribs on the tile. D D are the spaces which intervene between the strips and the tile-sections before this deposit is made. |
