Improvements in Metal Sashes.
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents
45 Sonthampton Buildings in the County of Middlesex, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to metal sashes or frames for holding the glass or other
transparent or semi-transparent material of a window, door or the like. Glass,
especially art glass which is made to embody designs of various kinds, has been
hitherto usually set in a lead frame or sash. This lead frame or sash is difficult of
construction and expensive, and necessitates the use of solder in securing the glass
or other transparent material therein, thus rendering skilled labour necessary,
while in addition, various devices, such as metallic rods and wires are frequently
found to be necessary to be employed in order to prevent the glass from bulging or
sagging. By the employment of my invention the objections above noted are
obviated, and a strong and durable panelled window, or a window embodying any
desired design, may be constructed at a greatly reduced cost. The invention
consists in a metallic frame work or sash of peculiar character and construction,
and in the combination therewith of suitable fastening devices adapted to secure
the parts of the said sash or frame work together, all as will be more fully herein-
after set forth and referred to in the claims.
In the accompanying drawings illustrating the invention Fig. 1 is a view of the
improved frame or sash enclosing panels of glass and held in a suitable frame.
Fig. 2 is a view in cross section of one of the sash bars and portions of the glass
panels, this figure showing one form of fastening device. Fig. 3 is a view of the
same at a point between the fastening devices. Fig. 4 is an enlarged view of a
part of the back frame, this figure showing portions of several ribs cut away
sufficiently to allow for the insertion and securing therein of fastening bolts. Fig. 5
represents in cross section one of the sash bars, and shows a portion of the same
extended through a perforation in the front frame to form a fastening device
adapted to be bent as indicated by dotted lines.
In the following description similar numbers of reference designate corresponding
parts throughout the drawings. In the said drawings 5 indicates a solid frame of
wood or metal surrounding the glazed sash. At 6 is shown a top-frame or lattice-
work forming part of the metal frame or sash, and which may be stamped or cut
in any well known manner out of sheet metal and in any desired design. It is
provided with perforations through which extend the shanks of the fastening
devices hereinafter described, the bars or strips 7 being each of sufficient width to
overlie and hold the edges of two adjoining panels 8-8 over which the frame is
placed. At 9 is an under-frame which is formed of the same design as the frame 6
and is a counter part thereof. Each bar of the under frame 9, is, however,
T-shaped, it having the separating and strengthening and panel-supporting rib 10
pressed up therefrom, or if desired, cast in one piece therewith. Portions of this
rib are cut away at predetermined points to allow the insertion therein of the
fastening bolts 11 which are preferably soldered to these ribs and are provided with
fastening nuts 12.
In place of the bolts 11, portions of the ribs 10 may be extended to form
tongues 10', which are inserted through the perforations in the portions of the front

page_text: frame 6 and are bent over as indicated in dotted lines Fig. 5 to secure the top-
frame and under-frame together. The panels of glass or similar material 8-8 arc
first placed in the frame 9, the ribs lying between their edges and separating
them. The frame 6 is then placed over the whole so that the portions 7 will cover
the ribs 10 and the edges of the panels. The frame 6 is now pushed downwardly,
thereby forcing the bolts 11 or other fastening devices through the perforations in
the frame 6. The nuts 12 may now be screwed on the bolts 11, or the ends of the
fastening strips bent over, and the glazed sash is ready to be enclosed in a solid
outer frame 5 of wood, metal or other suitable material.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent I declare that what I claim is :-
1. A metal sash adapted to contain panels of glass or similar material, the same
being composed of front and back frames each formed of sheet metal having
designs cut or stamped therefrom, as set forth.
2. The combination with front and back frames stamped from sheet metal, one or
both thereof having strengthening ribs 10, of fastening devices adapted to hold the
frames together, as set forth.
3. The combination with the frame 9 having ribs each provided with a fastening
device secured to the same, and panels of glass or similar material held in place
between such ribs, of the frame 6 having bars 7 formed with perforations through
which the fastening devices pass, substantially as set forth.
