Improvements in Sliding Windows.
I WILLIAM YOULTEN of 159 Victoria Street Westminster in the County of
London, Architect, do hereby declare the nature of this invention to be as
follows:-
The objects of this invention are
(a) To provide readily accessible though concealed pulleys.
(6) The concealment combined with accessibility and non-disturbance of the
vertical lines of the chains or cords which connect a pair of sliding sashes when
linked to each other by means of a pair of chains or cords so that when sliding,
each sash balances the other.
(c) To provide for the prevention of the sliding of the sashes beyond a given
point.
(d) To prevent the inconvenience arising from any stretching of the said chains
or cords.
To effect the object (a) I use a form of pulley which can be readily removed for
the purpose of facilitating the renewal of chains or cords affording the connection
between the sashes. This provides for the pulley-carriage plate to take its
bearing in or about the centre of the thickness of the pulley-stile at or about the
level of the top rail of the top sash when the latter is closed. Cast therewith and
at right angles to the same is the face or fixing plate the position of which is about
flush with the room face of the inside lining. By removing the screws from the
said fixing plate the pulley (attached) can easily be drawn into the room for the
purpose of passing a new cord or chain over the same when necessary.
Object (6) is attained owing to the fact that the position given to the pulley
wheel by such an arrangement is in a direct vertical line with the chain attach-
ment to the sashes and enables the concealment of the cords or chains to be readily
effected.
In order to carry out object (c) I provide in the pulley stile, grooves of the
required height, in which slide pivot like projections to which the chains or cords
are attached, or other suitable means.
I effect object (d) by providing in connection with the attachment of the chain
or cord to the sash a screw or other suitable means of tightening the chain as may
e necessary to render it properly taut.

I WILLIAM YOULTEN of 159 Victoria Street Westminster in the County of
London, Architect, 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 this invention are
(a) To provide readily accessible though concealed pulleys.
(b) The concealment combined with accessibility and non-disturbance of the
vertical lines of the chains or cords which connect a pair of sliding sashes when
linked to each other by means of a pair of chains or cords so that when sliding,
each sash balances the other.
(e) To provide for the prevention of the sliding of the sashes beyond a given
point.
(d) To prevent the inconvenience arising from any stretching of the said chains
or cords.
To effect the object (a) I use a form of pulley which can be readily removed for
the purpose of facilitating the renewal of chains or cords affording the connection
between the sashes. This provides for the pulley-carriage plate to take its
bearing in or about the centre of the thickness of the pulley-stile at or about the
level of the top rail of the top sash when the latter is closed. Cast therewith and
at right angles to the same is the face or fixing plate the position of which is about
flush with the room face of the inside lining. By removing the screws from the
said fixing plate the pulley (attached) can easily be drawn into the room for the
purpose of passing a new cord or chain over the same when necessary.
Object (b) is attained owing to the fact that the position given to the pulley
wheel by such an arrangement is in à direct vertical line with the chain attach-
ment to the sashes and enables the concealment of the cords or chains to be readily
effected.
In order to carry out object (c) I provide in the pulley stile, grooves of the
required height, in which slide pivot like projections from the sashes to which the
chains or cords are attached, or other suitable means.
I effect object (d) by providing in connection with the attachment of the chain
or cord to the sash a screw or other suitable means of tightening the chain as may
be necessary to render it properly taut.
And in order that my invention may be more clearly understood I will proceed
to describe the same with reference to the drawings accompanying this specifi-
cation which shew my invention as applied to a window having pivotted sliding
sashes and in which
Fig. 1 is a section through head of frame,
Fig. 2 a plan shewing position of pulley wheel in pulley stile,
Fig. 3 a plan shewing grooves in pulley stile, and
Fig. 4 an elevation of pulley stile facing sashes.
The same letters of reference denote the same parts in all views.
a shews the bottom sash, 6 the top sasb, c the pulley wheel, d the pulley frame,
dface plate of pulley frame, e the chain, one end of which is connected to the
bottom, and the other to the top sash. f Fig. 3 shews a pin projecting from the
sash a, and provided at its outer end with an adjustable chain connection g.
A similar pin is provided to each side of each sash, and the ends of the chains e are
attached thereto, so that each sash balances the other. h shews grooves in the
pulley stile in which the chain attachments g slide. These grooves extend up the
pulley stile to the centre line x (see Fig. 4) where they meet other grooves i in

page_text: the back of the pulley stile. These grooves i are shewn by dotted lines in Figs. 3
and 4.
It will be seen (a) that the pulley c is concealed but may be readily removed by
withdrawing the screws from the face plate d',
(b) that the position given to the pulley wheel c is in a direct vertical line with
the chain attachments to the sashes, so that the chains, while easily accessible, are
concealed, and each sash balances the other; (c) that the grooves h regulate the
sliding of the sashes; and (d) that by means of the adjustable connections at g the
chains e may be tightened or slackened as required.
Having now particularly described and ascertained 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 improvements in sliding windows substantially as and for the purposes set
forth.
