of Berks, for the Invention of "IMPROVED MEANS OF HANGING' OR SUP-
PORTING WINDOW SASHES, APPLICABLE ALSO TO OTHER SIMILAR PURPOSES.”
Sealed the 9th September 1876, and dated the 29th March 1876.
PROVISIONAL SPECIFICATION left by the said Henry Charles Tucker at the
Office of the Commissioners of Patents on the 29th March 1876.
HENRY CHARLES TUCKER, of Little Faringdon, in the County of Berks. "IM-
PROVED MEANS OF HANGING' OR SUPPORTING WINDOW SASHES, APPLICABLE ALSO
TO OTHER SIMILAR PURPOSES."
My Invention relates to a contrivance for supporting hanging window sashes
without the use of counterweights or lines, and it is also applicable to shutters
sliding in vertical grooves, to domestic lifts, and in other similar cases.
As applied to window sashes the contrivance of my Invention consists in strips
of india-rubber in combination with wheels mounted in the sash frame, as hereafter
described.
An india-rubber strip is let into a groove made in each of those parts of the
window frame usually called the pulley stiles, which designation I shall for con-
venience retain although there is no pulley mounted in the style. Each strip is in
the position usually occupied by the sash line and pulley, and it preferably projects
slightly from the surface of the pulley stile, and has a convex or rounded face
against which runs a wheel or roller (one or more) mounted in the sash stile, the
said wheel or roller having a toothed, serrated, grooved, or other shaped periphery
which presses against and embeds in the india-rubber strip, the latter thus cou-
stituting a sort of elastic rack and the wheel a rack wheel, in addition to which a
small square or polygonal roller may be mounted to run against the same strip.
The india-rubber strip for the upper sash is more deeply recessed at the upper
extremity to relieve the wheel when the sash is in the closed position. In the sash
stile at the lower part a wheel made of india-rubber is mounted so as to press and
run against the pulley stile; this wheel becomes flattened by the pressure against
the pulley stile, and in conjunction with the india-rubber strip and toothed wheel
serves to sustain the window sash in any position in which it may be placed, and
prevent rattling whilst permitting the sash to be raised and lowered with the
requisite facility.

HENRY CHARLES TUCKER, of Little Faringdon, in the County of Berks.
PROVED MEANS OF HANGING OR SUPPORTING WINDOW SASHES, APPLICABLE ALSO
TO OTHER SIMILAR PURPOSES."
My Invention relates to a contrivance for supporting hanging window sashes
without the use of counterweights and lines, and it is also applicable to shutters
sliding in vertical grooves, to domestic lifts, and other light bodies sliding in vertical
grooves.
As applied to window sashes the contrivance of my Invention consists in strips of
india-rubber fixed either to the sash stiles or to the pulley stiles or frame in com-
bination with wheels or rollers pressing against the said strips, and mounted in the
one case in the pulley stiles, or in the other case in the sash stiles, as hereafter
described.
The wheels or rollers have a toothed, serrated, grooved, or otherwise roughened
periphery which presses against and embeds itself in the india-rubber strip, the
latter thus constituting a sort of clastic rack. In the sash stile at the lower part a
wheel made of india-rubber is mounted so as to press and run against the pulley
stile; this wheel becomes flattened by the pressure against the pulley stile or frame,
and in conjunction with the india-rubber strip and toothed wheel serves to sustain
the window sash in any position in which it may be placed and prevent rattling.
In order that my Invention may be more readily understood, I will proceed to
describe it more fully as applied to window sashes with reference to the annexed
Drawings, in which,—
Figure 1 represents an edge view of the sashes.
Figure 2, the sash grooves, the sashes being removed.
Figure 3, an inside view of part of the lower sash, drawn about full size; Figure 4,
a cross section of same on line 1-1, Figure 3.
Figure 5 a view, also full size, of the middle portion of the sash grooves where the
sashes meet; and Figure 6 an edge view of part of one of the lower sashes.
In all these Drawings I have shown the arrangement which I prefer, viz., the
india-rubber strip fixed to the sash stilc, and the rack wheel or roller in the pulley
stile or frame.
For convenience I retain the ordinary designation of the pulley stile although no
pulleys are used. A is the upper sash, and B the lower sash. Referring to the
lower sash, C is a strip of vulcanized india-rubber of round or square form in cross
section laying partly in a groove D in the sash stile, and partly projecting beyond
the same, as shown. The india-rubber strip extends from the top nearly to the
bottom of the sash, and is fixed at either end by metal plates or clamps E screwed
to the sash. F is a toothed wheel mounted in a suitable case fitted in the pulley
stile, from the surface of which the wheel partly projects. The wheel is opposite
the india-rubber strip C, and at such a height that when the sash is down it will
press against the india-rubber strip C at the upper part and embed itself therein,
as shown. G is a spring titted in the wheel case and pressing against the teeth of
the wheel to prevent it rotating too freely; H is a vulcanized india-rubber wheel
mounted at the lower part of the sash. The bracket in which wheel H is mounted
is bent outwards, and serves as a spring to press the wheel against the pulley stile.
I, groove at the bottom part of the stile to relieve the india-rubber wheel of the
pressure when the sash is in the closed position. Both sides of the sash are
similarly fitted, and the upper sash is likewise provided with india-rubber strips
and wheels at each side. In this case however the india-rubber wheel H is at the
top of the sash, and the wheel F is mounted in the pulley stile in such a position as
to be opposite the lower end of the india-rubber strip C when the sash is in its
highest or closed position, as shown.

page_text: It will be readily understood without further description how the india-rubber
strips might be fixed to the pulley stiles and the toothed wheels to the sashes.
Having described the nature of my Invention, and the manner of performing the
same, I declare that what I claim as my Invention to be protected by the herein-
before in part recited Letters Patent is,
First. The employment of an india-rubber strip or clastic "rack" in combination
with a toothed wheel working against the same, as described, and the application
thereof, substantially in the manner shown and described, and for the purposes
specified.
Second. The employment in combination with the india-rubber strip and toothed
wheel applied, as described, of the india-rubber wheel H, substantially as and for
the purpose specified.
In witness whereof, I, the said Henry Charles Tucker, have hereunto set my
hand and seal, this Twenty-sixth day of September, in the year of our Lord
One thousand eight hundred and seventy-six. .
