Improvements in Window Sashes.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord Street,
Liverpool, and 6, Bank Street, Manchester, both in the County of Lancaster, and
Lower Temple Street, Birmingham, in the County of Warwick, Civil Engineer,
do hereby declare the nature of this invention to be as follows:
The invention has for its object to provide an improved sash particularly fitted
for use in car windows, although capable of more general use. It is desirable that
sashes for car windows should combine great strength with comparative lightness;
while at the same time presenting a construction which will permit of the ready
removal of a broken pane of glass and the insertion of another pane. By the
employment of the present invention a sash meeting these requirements is pro-
duced.
The top and bottom rails of the sash are formed preferably from wood, the edge
which receives the glass in one or both of the said rails being rebated or cut away
at the inner side to permit of the glass being placed in position in the said rails.
When only one of the said rails is rebated, the other will be grooved or channeled
to receive the edge of the glass. After the glass has been placed in position, a
beading of wood or other suitable material is placed next the glass on the rebated
edge of the rail, and secured in place by nails or other suitable securing means.
The stiles each comprise an exterior piece, preferably of metal to give rigidity,
strength and durability to the sash, and which exterior piece is of L or angle shape
in cross section. The said metal piece forms the exterior surface of the stile,
as also the lateral edge portion thereof. Inside of the said metal piece I place
an L-shape or rebated strip, preferably of wood, against the thinner or rebated edge
of which the edge of the plate of glass abuts. A packing of rubber or the like is
employed between the flat side of the glass and the main was of the stile.
flanged or thicker portion of the said rebated strip is of a thickness equal to the pro-
jecting portion or flange of the metal part of the stile so that when the said rebated
strip is placed inside the said metal part the surface of the thicker portion of the
said rebated strip will be substantially flush with the edge of the said projecting
portion or flange of the said metal part. The said strip is secured to the metal part
by screws or other suitable securing means. A retaining strip is placed in the
rebate in the said rebated strip, said retaining strip being of a thickness equal to
the depth of the said rebate. It projects over the edge of the glass so that the
latter is firmly held, and it is secured to the rebated strip and metallic part by
means, preferably, of screws which may be unscrewed from the inside of the car
when it is desired to remove the retaining strips in order to take out
The

parts of the two stiles project across the ends of the top and bottom
rails, the latter being grooved or cut away to receive the ends of said
metallic parts. The said top and bottom rails are united to the ends of the
said metallic portions of the stiles by means of screws or similar securing devices.
By the construction above set forth a very strong, durable and relatively light
sash is obtained, which may be employed with advantage where, as in the case of
windows which are curved vertically, there is considerable wear on the stiles in
opening and closing the 'windows. The said construction affords a ready means of
removing a broken pane and inserting in. place thereof a new pane. Meto

I, WILLIAM PHIllips Thompson, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord Street,
Liverpool, and 6, Bank Street, Manchester, both in the County of Lancaster; and
Lower Temple Street, Birmingham, in the County of Warwick, Civil Engineer,
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:
T
My invention has for its object to provide an improved. sash which shall be more
particularly fitted for use in car windows, although capable of more general use.
My invention is fully set forth in the following description, and the novel features
thereof; are pointed out and clearly defined in the claims at the end of this specifica-
tion. In the said description reference is made to the accompanying drawings, in
which Fig. 1 is an elevation of a window sash embodying my invention. Fig; 2
is a section on line 2-2 of Fig. 1. Fig. 3 is a detail of one corner of the sash
showing the construction more clearly. Fig. 4 is a view in vertical section on the
line 4 4 of Fig. 1.
It is desirable that sashes for car windows should combine great strength with
comparative lightness, while at the same time presenting a construction which will
permit of the ready removal of a broken pane of glass and the insertion of another
pane. By the employment of my invention a sash meeting these requirements
is produced.
Having reference to the drawings, 1 is the glass of the window, 2 is the bottom
rail, 3 is the top rail, and 4, 4, the stiles of the sash. The top and bottom rails
are formed preferably from wood, the edge which receives the glass in one or both
of the said rails being rebated or cut away at the inner side to permit of the glass
being placed in position in the said rails. When one only of the
said rails is rebated, the other will be grooved or channeled to receive
the edge of the glass. After the glass has been placed in position
a beading 5 of wood or other suitable material is placed next the -glass
the rebated edge of the rail, and secured in place by nails 6 or
other suitable securing means. The stiles each comprise an exterior piece 7, pre-
ferably of metal to give rigidity, strength and durability to the sash, and which
exterior piece 7 is of the L or angle shape in cross-section that is shown in Fig. 2.
These metal pieces form the exterior surface of the sash, as also the lateral edge
on
ic

page_text: The
portions thereof. Inside each of the said metal portions, I place an L-shaped or
rebated strip 8, preferably of wood, against the thinned or rebated edge 9 of which
the edge of the plate of glass abuts. A packing 19 of rubber or the like is employed
between the glass and the stile. The thicker portions of the said strip 9 is of a
thickness equal to the projecting portion of the metal part 7 of the stile, so that when
the said strip is placed inside the said metal portion 7 the surface of the thicker
portion of the said strip 9 will be substantially flush with the edge of the
said projecting portion of the said metal part 7, as will be clear from Fig. 2.
said strip 8 is secured to the metal portion 7 by screws 10 or other suitable securing
means. A retaining strip 11 is placed in the rebate in the said strip 8, said strip 11
being of a thickness equal to the depth of the said rebate. It projects over the edge
of the glass so that the latter is firmly held, and the strip 11 is secured to the
strip 8 and metallic portion 7 by means, preferably, of screws 12, which may be
unscrewed from the inside of the car when it is desired to remove the retaining
strips 11 in order to take out a broken pane and replace it by a new one.
The
ends of the metallic portions 7 project across the ends of the top and bottom rails,
the latter being grooved or cut away to receive the ends of said metallic portions 7.
The said top and bottom rails are united to the ends of the said metallic portions
of the stiles by means of screws or similar securing devices. By the construction
above set forth a very strong, durable and relatively light sash is obtained, which
may be employed with advantage where, as in the case of windows which are
curved vertically, there is considerable wear on the stiles in opening and closing
the windows. The said construction affords ready means of removing a broken
pane and inserting in place thereof a new pane.
Having now particularly ascertained and described the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
The improved sash comprising the top and bottom rails, one or both thereof
being rebated and having the removable securing strip provided with means to
retain it in place, and the stiles consisting of each of the L-shaped metal exterior
piece, the rebated strip 8 against which the edge of the pane of glass abuts, and
the removable retaining strip located in the rebate of the said rebated strip,
overlying the said pane, and provided with means to secure it in place, substan-
tially as described.
