Improvements in or applicable to Sash Windows.
JOHN HARROP JONES of The Old Stocks, Cheetham Hill Road Manchester
in the County of Lancaster Joiner and Builder do hereby declare the nature of
this invention to be as follows:-
:-
The objects of this invention are so to form and arrange a sliding sash window
that it can be opened (like a casement window) for cleaning or any other purpose,
and also to improve the pulleys, weights and pockets of sash windows, to render the
same more simple and convenient.
According to the first part of my invention I dispense entirely with the parting
beads and outside guiding beads usually employed and I run the sash cords in deep
grooves made in the inner faces of the window frame.
The right hand or hinge side of the sash frame I make with a continuous
projection or tongue to run in this groove. The left hand side of the window frame
or pulley stile I make with a double rebate like a door casing and I form the left.
stile of each sash frame with a corresponding rebate to close against the same like
a door or a casement window.
In the deep groove of the left hand pulley stile or frame slides a metal block to
which the end of the sash cord is fixed by screws or otherwise.
This block projects outwards beyond the face of the stile and at that part of the
sash stile which comes opposite to the said block when the sash is sufficiently raised
to clear the window bottom I make a horizontal notch or recess in the sash stile so
that when closing the sash into the window frame (like a door or casement) the
projecting part of the block comes into this notch and thus obtains a hold on the
sash frame. Above this notch is fixed a metal or wooden projection which passes
into the groove in the pulley stile and keeps the sash in its place, and the latter can
then slide up and down carrying the block with it, the block sliding in the groove
in the pulley stile and acting as a tongue to keep the sash in its place.
This sliding block or cord holder may also be applied to existing sashies.
Near the bottom of the groove a catch lever is provided which allows the block
to slide down to the bottom of the groove but arrests its upward movement above
the point previously named when the sash is just raised clear of the window bottom,
when as before stated the sash can be opened as a door or casement leaving the
block in the groove in the pulley stile, and the said catch lever will hold the block
in this position (with the weight suspended at the other end of the cord) until the
sash is closed and the catch lever withdrawn when the sash frame will work up and
down in the usual manner.
Excepting at the times when the sash is required to open inwards on its hinges
the catch lever is held out of action by a small catch and does not in any way
interfere with the ordinary movement of the sash.
A pin or peg may be used for this purpose but I prefer the catch lever as it is
self acting.
The hinges are made like those of a gate or an oven door so that when the sashes
are raised the gudgeon will draw upwards out of the eye or socket and I prefer to
make the gudgeon of the lower hinge with a horizontal projection or fang and the
socket plate with a corresponding groove or notch so that the fang can pass
through it but when the sash is opened the fang or projection turns under the
socket plate and prevents the sash from being lifted (accidentally or otherwise) off
its hinges.
It will of course be understood that the sashes may be hinged from the left
instead of the right if preferred.

page_text: I carry the cords upwards as usual over pulleys which are supported in the
following way.
I mortise a hole through the pulley stile at the back of which I pass a spindle
through from the inside casing to the outside casing. The pulleys work on this
spindle the inner end of which is formed with a plate or head which may be made
ornamental and let into the inside casing to which it is screwed or otherwise
fixed.
From this spindle or by preference from a plate or plates fixed to the back of
the pulley stile, project staples or loops which keep the cords in place and act as
guides for the pulleys to work against and also by partly surrounding the latter
prevent them from falling backwards when the spindle is withdrawn for renewing
one or both of the said pulleys, which can thus be removed from the stile with the
greatest ease. If the pulleys are small the back of the pulley stile must be
grooved or cut away for the spindle to pass through.
It will be evident that this part of my invention can be applied to all kinds of
sash windows.
I make my weights all of one height varying in diameter or thickness according
to the weight of the windows and instead of making a long pocket hole in the
pulley stile to pass the weight through I make a short pocket at such a height that
the top of the weights comes opposite the pockets and thus the cords can be attached
to the said weights.
I make the inside casing so that it can be taken off for inserting the weights
which must be done before the architraves are fixed.

COMPLETE SPECIFICATION.
Improvements in or applicable to Sash Windows.
I JOHN HARROP JONES of The Old Stocks Cheetham Hill Road Manchester
in the County of Lancaster Joiner and Builder, 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 objects of the invention are so to form and arrange a sliding sash window
that it can be opened (like a casement window) for cleaning or any other purpose,
and also to improve the pulleys, weights, and pockets of sash windows and to render
the same more simple and convenient.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the two sheets of drawings hereunto annexed and the following explanation
thereof.
The first part of my invention relates to the improved construction and
arrangement of sash windows whereby I am enabled by simple and convenient
means to provide for the opening of the same when required like a casement
without interfering with their ordinary rising and falling movement as sash
windows.
Fig. 1 is a sectional elevation of a window frame and window constructed
according to my invention.
Fig. 2 is a vertical section through the line A B and Fig. 3 a horizontal
section.
Figs. 4 and 5 are vertical sections hereinafter more particularly referred to, and
Figs. 6 to 10 inclusive are detached views of parts of the invention drawn to
a larger scale.
According to the first part of my invention I dispense entirely with the parting

page_text: beads and inside guiding beads usually employed, and I run the sash cords a in
deep grooves made in the inner face of the window frame c.
The right or hinge side of the sash frame d I make with a continuous projection
or tongue e (see section Fig. 3) to run in this groove.
The left hand side of the window frame or pulley stile c I make with a double
rebate like a door casing (see Fig. 3) and I form the left stile of each sash frame d
with a corresponding rebate to close against the same like a door or a casement
window.
In the deep groove of the left hand pulley stile or frame e slides a metal
block e to which the end of the sash cord a is fixed by set screws or otherwise
(see Figs. 7 and 8).
This block e projects outwards beyond the face of the pulley stile c (see Fig. 8)
and at that part of the sash stile d which comes opposite to the said block e when
the sash dis sufficiently raised to clear the window bottom I make a horizontal notch
or recess (see Fig. 1) in the sash stile so that when closing the sash d into the
window frame e (like a door or casement) the projecting part of the block e comes
into this notch and thus obtains a hold on the sash frame d.
Above this notch is
fixed a metal or wooden projection (see detached section Fig. 6) which passes
into the groove of the pulley stile and keeps the sash in its place, and the
latter can then slide up and down carrying the block e with it, the block sliding
in the groove in the pulley stile and acting as a tongue to keep the sash in
its place.
This sliding block or cord holder e may also be applied to existing sashes.
Near the bottom of the groove a catch lever (Figs. 7 and 8) is provided
which allows the block e to slide down to the bottom of the groove (see Fig. 7) but
being pulled over into the dotted position arrests its upward movement above the
point previously named when the sash is just raised clear of the window bottom,
when as before stated the sash can be opened as a door or casement leaving the
block e in the groove of the pulley stile or frame and the said catch lever / will
hold the block e in this position (with the weight i suspended at the other
end of the cord) until the sash is closed and the catch lever is withdrawn
into its vertical position, when the sash frame will work up and down in the
usual manner.
Excepting at the times when the sash d is required to open inwards on its hinges
the catch lever is held out of action in the position drawn in full lines at Fig. 7
by means of a small catch or notch and it has to be raised up clear of this
catch or notch before it can be turned over into the dotted position. A pin or
peg may be used for this purpose but I prefer the catch or notch as it is
self acting.
し
The hinges are made like those of a gate or oven door so that when the sashes
are raised the gudgeon will draw upwards out of the eye or socket and I prefer to
make the gudgeon of the lower hinge (as shown at the detached view Fig. 10) with
a horizontal projection or fang * and the socket plate with a corresponding notch
(like a keyhole) so that the fang can pass through it but when the sash is
opened the fang or projection * turns under the socket plate and prevents the
sash from being lifted (accidentally or otherwise) off its hinges, when opening
inwards.
It will of course he understood that the sashes may be hinged from the left
instead of the right if preferred. I carry the cords upwards over pulleys m
which are supported in the manner illustrated on Sheet 2 of the drawings,
(Figs. 11, 12 and 13).
I mortise a hole n through the pulley stile e at the back of which I pass a
spindle o through from the inside casing to the outside casing. The pulleys m
work on this spindle the inner end of which may be formed with a plate or head
which may be made ornamental and let into the inside casing to which it is screwed
or otherwise fixed.
From. this spindle o, or by preference from a plate or plates fixed to back of the

page_text: pulley stile project staples or loops p which keep the cords a in place and act as
guides for the pulleys m to work against, and also by partly surrounding the latter
prevent them from falling backwards when the spindle o is withdrawn for renewing
one or both of the said pulleys, which can thus be removed from the stile with the
greatest ease.
If the pulleys m are small the back of the pulley stile e must be grooved or cut
away as shown at Fig. 14 for the spindle o to pass through.
Fig. 15 shows the spindle o held in its place by a small strap g screwed to the
pulley stile, and the staple or loop p rivetted to the spindle.
It will be evident that this part of my invention can be applied to all kinds of
sash windows.
I make my weights all of one height varying in diameter or thickness according
to the weight of the window, and instead of making a long pocket hole in the
pulley stile to pass the weight through, I make a short pocket at such a height that
the top of the weights comes opposite to the pockets and thus the cords can readily
be attached to the said weights.
I also make the inside casing so that it can be taken off for inserting the weights
which must be done before the architraves are permanently fixed on.
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
First. In a sliding sash window so constructed and arranged that it can be
opened on hinges like a door or casement when desired, the combination of a block
fixed to the end of the sash cord and sliding in a groove in the pulley stile or frame
and partly projecting therefrom, of a corresponding notch in the sash frame, so
placed that when opening or closing the latter (like a door or casement) the notch
in the sash frame can be withdrawn from the said sliding block so as to release the
sash cord from the sash and allow the latter to open, and when the same is closed
again the said notch will pass over or onto the sliding block and so connect the sash
and the cord together again that the block can slide vertically in the groove in the
pulley stile and act as a tongue to keep the sash in its place.
Secondly. I claim the application near the bottom of the groove in the pulley
stile of a catch lever which when raised and pulled over into a horizontal position
comes above the said sliding block so as to arrest its upward movement and prevent
the weight from lifting the block whilst the sash is open on its hinges, so that the
block will be held in position to allow the notch in the sash to pass over it when
the sash is closed again.
Thirdly. I claim the devices shown on the drawings and hereinbefore described
for mounting the pulleys in the pulley stiles, and
Fourthly claim the general novel construction and arrangement of the sash
window frame and its adjuncts to facilitate its being opened and closed on hinges
like a casement or door when required for cleaning or other purposes as
hereinbefore particularly set forth and described and illustrated by the drawings
annexed.
