ROBERT COTTON, 16, Wilson Street, Newcastle, Staffordshire, Mechanic,
and HENRY TODD, near Board Schools, Etruria, near Stoke-on-Trent, Foreman of
Brick and Tile Works, do hereby declare the nature of this invention to be as
follows:-
The object of our invention is improvements in sliding and reversable window
sashes and frames.
And consists of a device for preventing wind and rain from blowing through the
joints of such windows.
Also for dispensing with steel springs and metal slides thus allowing sash to be
more easily removed in case of necessity.
At same time diminishing friction caused by such springs thus taking less force.
to raise and lower sashes.
Also making our improvements more readily applied to any window and is con-
structed in the following manner.
There is a strip of hard wood or suitable material with a groove or rabbet cut
or formed into one edge to recive a core of approximate size and of suitable shape
and of suitable material strong indiarubber tube for preference.
The tube is forced against sash and stop bead or parting bead by the action of
a metal strip of tee shape which is placed in bottom of groove.
The hard wood strip the metal strip and the core are all secured to the sides of
sashes by means of two metal disks a indiarubber washer and a nut and pin in
such a manner that they are free to slide up and down frame when window is
intended to be open.
But when window is almost closed the metal strip which has one edge cut in
such a manner that it wedges itself further out of groove thus pressing one portion
of the indiarubber tube or its equivalent against the sash and the other against
the bead for the purpose of making the joints airtight and watertight.
The wood strip has a hole bored in the back a certain depth and diameter to
suit the metal disks and indiarubber washer.
At the bottom of the said hole there is a smaller hole cut through to recive a
square boss or projection that is on one side of one disk for the purpose of pre-
venting disk from turning round and for forming a bush for pin to work in.
The pin is riveted to a plate which is secured to side of sash approximately to
suit the holes in the disks and strip.
The disk with square projection is driven to the bottom of hole in strip which is
then placed upon pin.
The indiarubber washer which is smaller then the hole in strip to allow for
expansion is also placed upon pin then the other disk which has a square hole in
center that will fit the square part of pin to prevent pin from turn round without
washer is placed upon pin the nut is then screwed up until there is sufficient
tension or presure upon indiarubber washer or pin to hold sash in anny required
position and to keep a close joint between sash and strip.

draught.
We serve each side of each sash of reversible windows in the said manner and of
ordanary sliding windows partly in the said manner thus stopping vibration and

Improvements in Sliding and Reversing Window Sashes and Frames.
ROBERT COTTON, 16, Wilson Street, Newcastle, Staffordshire, Mechanic,
HENRY TODD, near Board Schools, Etruria, Staffordshire, Foreman of Brick, and
Tile Works, 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:
The object of our invention is improvements in sliding and reversible windows
sashes and frames.
And consists of a device for preventing wind and rain from blowing through the
joints of such windows.
"
Also for dispensing with steel springs and metal slides thus allowing sash to be
more easily removed in case of necessity.
At same time diminishing friction caused by such springs thus taking less
force to raise and lower sashes.
..
Also making our improvement more readily applied to any window and is con-
structed in the following manner.
There is a strip of hard wood or suitable material with a groove or rabbet cut or
formed into one edge to recive a core of approximate size and of suitable shape
and of suitable material strong indiarubber tube for preference.
The tube is forced against sash and stop bead or parting bead by the action of a
metal strip of tee shape which is placed in bottom of groove.
The hard wood strip the metal strip and the core are all secured to the sides of
the sashes by means of two metal disks an indiarubber washer and a nut and pin
in such a manner that thay are free to slide up and down frame when window is
intended to be open.
But when window is almost closed the metal strip which has one edge cut in
such a manner that it wedges itself further out of groove thus pressing one portion
of the indiarubber tube or its equivalent against the sash and the other against
the bead for the purpose of making the joints airtight and watertight.
The wood strip has a hole bored in the back a certain depth and diameter to
suit the metal disks and indiarubber washer.
At the bottom of the said hole there is a smaller hole cut through to receive a
square boss or projection that is on one side of one disk for the purpose of prevent-
ing disk from turning round and for forming a bush for pin to work in.
The pin is riveted to a plate which is secured to side of sash approximately to
suit the holes in the disks and strip.
The disk with square projection is driven to the bottom of hole in strip which is
then placed upon pin.
The indiarubber washer which is smaller then the hole in strip to allow for

page_text: expansion is also placed upon pin then the other disk which has a square hole in
center that will fit the square part of pin to prevent pin from turning round with-
out washer is placed upon pin the nut is then screwed up until there is sufficient
tension or pressure upon indiarubber washer or pin to hold sash in any required
position and to keep a close joint between sash and strip.
There is a plate of wood or metal secured to the top of strip to prevent up-
draught.
'
We serve each side of each sash of reversible windows in the said manner and of
ordinary sliding windows partly in the said manner thus stopping vibration and
making them tolerably airtight.
In order that our invention may be more easily understood we have appended a
sheet of drawings upon which we have illustrated the nature of our said improve-
ments.
Figure 1 shows the grooved or rabbeted edge of the hard wood strip.
Figure 2 is a vertical section of side of strip when window is closed and tee
strip forced out and core or tube forced against bead and sash. The tube is
secured to the tee strip.
Figure 3 is a similar section showing sash slightly raised tee strip back into
slot and tube released from bead and sash and free to slide up and down.
Figure 4 is a end section of sash and strips and windowframe one sash closed and
the tube or core under compression the other slightly raised and the tube released
and free to slide up and down.
On the same sash is shown the pin disks and washers and the way in which they
are applied.
The action of the said invention is as follows
S Figure 1 is the bottom of the rabbet or groove.
M Figure 1 is a narrow hole cut into bottom of the rabber or groove to admit of
certain parts of tee strip T shown on Figure 2 and 3.
Pon Figure 1 and 2 are slot plates with the top edge of slot beveled to suit the
wedge shaped ends of tee strip.
C Figure 2 and 3 is the tube or core.
The tee strip T projects below the bottom sash so that it reaches the bottom of
windowframe before the sash and when the sash goes the other part of distance it
wedges the tee strip forward and presses the tube or core against the bead B
Figure 2, 3 and 4 also against sash H Figure 4.
The tee strip projects above top sash thus working against the top of window-
frame to compress core.
V Figure 2 and 3 is a plate to stop the up draught.
D Figure 2 is a disk with square hole in center that fits on pin to stop nut N
from coming unscrewed when pin is being turned round.

R Figure 4 is the plate with pin riveted to it which is fastened to side of sash.
F is the disk with square projection or boss that forms the bush for pin to work
G is the pin. A is the indiarubber washer.
D is the disk with square hole in center.
N is the nut which when screwed up compresses indiarubber washer or its
equivalent thus always keeping hard wood strip X against the sash H.
Wis the weights used to balance the sashes.
If necessary the indiarubber tube may be inflated or it may be strengthened
with a web or webs in the inside.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
-
1st. The way and means hearin set forth of securing and pressing the supple-
mental strip, to and against the sides of sashes.

page_text: 2nd. The means hearin set forth and shown upon the accompanying drawings
for preventing wind and rain from blowing through the joints and stopping the
vibration of ordinary sliding sash windows and sliding and reversing sash windows.
