PROVISIONAL SPECIFICATION.
Improvements in the Construction of Window Sashes.
I, WILLIAM HENRY LINDSAY, of The Coil Clutch and Pulley Co. Ld., of
Ashton Gate Bristol, Managing Director do hereby declare the nature of this
invention to be as follows:-
This invention relates to window sashes in which metal sash bars are employed.
Where the bars meet they are connected by a boss formed with grooves to.
receive and fit upon the sash bars, one bar generally passing completely across the
boss and having the ends of the two transverse bars abutting against it. After
the bars are in place the boss is compressed by a suitable die or otherwise to make
it grip the bars firmly. In order still further to prevent the bars from moving in
the boss, depressions are formed in the latter and the flange of the bar is forced in.
places into these depressions by means of a punch.
I also form the sash bars of window sashes of a double trough section the outer
edges of the webs forming the sides of the troughs being turned inwards towards
the glass. A strip of india rubber or other elastic material or plastic material
such as putty is placed along one side of each trough and forms a bed against
which the face of the glass near its edge is pressed as hereinafter described the
pressure causing the turned in edge of the web of the sash to bed itself in the
rubber thus securing the latter in place.
On the other side of the glass there is a bar of angular section one side of the
angle bearing against the glass whilst the other side against the central web of the
bar the outer end of this side lying in the angle formed by the central web and
the turned in edge of the adjacent web. When this angular bar is put into place
it presses the other side of the glass against the rubber. In order to prevent the
glass from moving parallel to itself between the india rubber and the angular bar
the ends of the latter are slotted and the strips so produced are turned back forming
springs which when the bar is pressed into place spring out and rest against the.
edge of the glass.

I, WILLIAM HENRY LINDSAY, of The Coil Clutch and Pulley Co. Ld., of
Ashton Gate, Bristol, Managing Director, 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 :-

receive and fit upon the sash bars, one bar generally passing completely across the

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation of part of a window constructed according to my
invention,
Figure 2 is a section on the line 2-2 Figure 1.
Figure 3 is a back view of one of the bosses and
Figure 4 is a section on the line 4-4 Figure 3.
a is one of the bosses, b is a sash bar passing completely across it and
bare two bars whose ends abut against the bar b. These bars are of double
trough section having flanges cc at the lower end of their central web and
having the ends of its other webs turned inwards as shown at c¹ c. d Figure 3
are depressions in the boss into which the edges of the bars are forced. e Figure 2
is a sheet of glass. ff are strips of indiarubber or other elastic packing, and
gg are bars or packing pieces of angular section shown separately at Figures 5, 6
and 7 which are a plan, a side elevation and a perspective view respectively. One
side of each of the pieces g is slotted as shown and the strips g' thus formed are
turned back.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. The bosses slotted to receive the sash bars substantially as described.
2. The combination of a boss, a sash bar passing completely across it and two
other bars at right angles to the first with their ends abutting against it substan-
tially as described.
3. The method of fixing the bars to the boss substantially as described and
shown at Figure 3.
4. Sash bars of a double trough section with turned in edges c¹ c¹ substantially
as described.
5. The method of fixing the glass by the angular bars or packing pieces g
substantially as described.
6. Window sashes substantially as described and shown in the drawings.
