PRISMATIC PLATE AND FRAME FOR SAME.
SPECIFICATION forming part of Letter Patent No. 586,261, dated July 13, 1897.
Application filed April 19, 1897. Serial No. 632,709. (No model.)
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 and produced new and useful Improvements in Prismatic Plates and Frames for Same, of which the following is a specification.
My invention relates to prismatic plates or plates comprising a series of prism-lights and to means for framing the same. It is illustrated in the accompanying drawings, wherein—
Figure 1 is a view of a series of prism-lights gathered together within a frame, the parts being placed in position ready to be secured together. Fig. 2 is an elevation of a complete prism-plate. Fig. 3 is a section therethrough on the line 3 3 of Fig. 2.
Like parts are indicated by the same letter in all the figures.
A is a surround lug channel-bar frame-piece into which a filler-frame of wood B may be let, the latter being made of any desired size or shape, so as to cause the complete device to properly fill the window or aperture. This frame may be put together by mitering the corners or otherwise, as indicated, the parts being properly secured together in any desired manner. It is then laid down upon a suitable table or bed C'. The several prism-lights are then arranged in the proper position within the frame, and the warps or ribbon-like strips C, running in one direction, are laid in position between the prism-lights, and the ties D or similar short strips are laid in the opposite directions between the prism-lights. Thus the parts are brought into the relation shown in Fig. 1. The corners of the prism-lights are cut off slightly, as indicated at E, and then indented, as indicated by dotted lines at F. This leaves a little square aperture or opening about the point of junction of the warps and ties. Of course these warps and ties maybe each made of a long strip, each being cut half-way across and the shorter parts being fitted together, if desired, though in some cases this would not be the best form.
The frame, or, as I have called it, "net," in the meshes of which, so to speak, the prism-
lights are laid, may be made up in any desired manner from warps and
ties or from short and long strips or otherwise. The indentation in
the surface of the edge of the prism-light having been formed, it is
evident that if a substance, such as solder, be deposited or forced into
the aperture about the junction of the warps and ties it will fill the
square opening, unite the warps and ties, and enter the indentations or
grooves, thus holding everything in position and making a complete plate
by uniting the several parts of the frame so as to form a sort of grid
or net and by uniting to such net the several sections or prism-lights.
I prefer to use solder for this purpose, and this when used on the
points where the warps and ties engage the inside edge of the middle
frame will result in fastening the parts together at that point also.
If now, after the parts have been so united to form the prism-plate,
it is thought best to further secure the joints, the entire product
may be immersed in an electrolytic bath and be there treated in any of
the well-known ways for the application of the electroglazing process.
While this method is applicable to any sort of glass or tile sections
intended to be united into a plate, it is peculiarly applicable to
prismatic lights and is intended by me particularly for that purpose.|
I have illustrated prism-lights rectangular in cross-section, but it is evident that my invention is equally applicable to various shapes of prism-lights. The squares here shown as cut out or formed at the corners of the prism-lights may be of any desired size, but probably ought to be much smaller than indicated in the proportions of the drawings. Moreover, the solder is shown in an excessive quantity. It need not extend beyond the surface of the body of the prism-light on either side. When the parts are all laid securely on a table, it will not of course form in any considerable quantity on the plain sides of the prisms, and if it so forms there it can be removed without danger to the plate, so as to leave that surface smooth and plain. By leaving this aperture or cavity between the corners of the prism-lights and about the members of the grid, net, or frame there is room for the introduction of solder in the indentations,
