BURGISS of 18 Hora Street. Newcastle-on-Tyne, Joiner ROBERT WILSON
39 Cromettee Street, Newcastle-on-Tyne, Joiner, do hereby declare the nature
of this invention to be as follows:-
This invention relates to an improved construction of compound window sash,
the inner sash of which (carrying the glass) swings on hinges and can when desired
be opened inwards, so that it may be cleaned in a convenient manner from the
inside, the object of the invention being to render such windows more secure, and
draught proof. The inner frames of the top and bottom sashes are hinged at
alternate sides, and the edge of the outer sliding bar is rebated at the hinge side,
at the front, the hinge being formed by an L shaped metal plate fixed on the inner
and projecting part of the edge, the hinge being thus formed a short distance inside
of the sliding bar, thus allowing the hinged frame to swing clear of any obstacles.
The rebated edges (the inner bar being formed corresponding to the outer) will
thus also close tightly together and prevent any draught passing between them.
The other inner sash is hinged much in the same manner, but instead of having
the edges rebated, a groove may be formed in one edge in which a beading on the
other can take, this may be employed also for the front sash in place of the rebated
edges. At the other side I provide a lock which serves to fasten the hinged sash
securely to the outer by means of a bolt in the latter, sliding into a recess in the
former, being actuated by a suitable key. When the sashes are unlocked, the
outer end of the bolt is caused to project into a recess formed to retain it, in
the pulley stile, thus allowing the hinged sash to be opened only when the sliding
sash is in the proper position, and preventing the latter being moved up down
until the bolt is reversed when the hinged sash is closed. To cause these edges of
the sashes to meet closely a beading is formed on each, the edges of which beadings
are recessed so that they fit tightly into each other when the sashes are closed, and
the bolts locked.
The pulley cords move in a groove in the pulley style, and a sliding slip is
fixed on the side of the sash frame projecting into the said groove, and recessed
so that the cord can lie within it and be fastened to it by a plate. The cord
is thus out of sight, and there is no necessity to use beads.

Improvements in Window Sashes.

BURGISS of 18, Hora Street, Newcastle-on-Tyne, Joiner, ROBERT WILSON
10 39, Cromettee Street, Newcastle-on-Tyne Joiner, 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 :-
This invention relates to an improved construction of compound window sash,

page_text: the inner sash of which (carrying the glass) swings on hinges and can when desired
be opened inwards, so that it may be cleaned in a convenient manner from the
inside, the object of the invention being to render such windows more secure, and
draught proof. The inner frames of the top and bottom sashes are hinged at
alternate sides, and the edge of the outer sliding bar is rebated at the hinge side,
at the front, the hinge being formed by an L shaped metal plate fixed on the inner
and projecting part of the edge, the hinge being thus formed a short distance
inside of the sliding bar, thus allowing the casement to swing clear of any
obstacles. The rebated edges (the inner bar being formed corresponding to the
outer) will thus also close tightly together, and prevent any draught passing
between them.
The other inner sash is hinged much in the same manner, but instead of having
the edges rebated, a groove may be formed in one edge, in which a beading on the
other can take; this may be employed also for the front sash in place of the
rebated edges.
At the other side, I provide a lock which serves to fasten the hinged sash
securely to the outer by means of a bolt in the latter, sliding into a recess
in the former, being actuated by a suitable key. When the sashes are unlocked,
the outer end of the bolt is caused to project into a recess formed to retain it, in
the pulley stile, thus allowing the hinged sash to be opened only when the
sliding sash is in the proper position, and preventing the latter being moved up or
down until the bolt is reversed when the hinged sash is closed. To cause these edges
of the sashes to meet closely, a beading is formed on each, the edges of which
beadings are recessed so that they fit tightly into each other when the sashes are
closed, and the bolts locked. The pulley cords move in a groove in the pulley
stile, and a sliding slip is fixed on the side of the sash projecting into the said
groove, and recessed so that the cord can lie within it and be fastened to it by a
plate. The cord is thus out of sight, and there is no necessity to use beads.
In order that this invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which
Figs. 1 and 2 are sectional plans of the sash and frame, one showing the hinged
window closed and the other open the section being taken through both sashes,
and
Figs. 3 & 4 are detail views of the slip to which the cord is attached.
A is the frame of the window constructed in the usual manner and provided with
the weights a and pulley stile A'. The sliding stiles B and B' are fitted at each
side with the sliding slips C rebated at the side next to the sash. These slide in
grooves a¹ in the pulley stile A' being held in place by the beading D slotted to
allow the sliding slip to pass freely up and down. The slip C is grooved and
perforated as shown more clearly in Fig. 3 to allow of the cord E being fixed.
This cord is passed through the perforation and lies in the grooves c¹ being
pressed on the small pins which hold it securely to the slip when the latter is
fitted to the stile of the sash. This is done by the plate F screwed to the slip C
and furnished with a tapped hole through which passes the screw f from the inner
side of the stile. The cord E is thus completely out of sight, and moves within
the groove a¹. The slips C serve in place of the ordinary beadings used to hold
the sashes, thus dispensing with the latter.
The casement or hinged sashes G G'are hinged as shown in Figs. 1 & 2 at
opposite sides to the stiles of the ordinary sashes, the hinges g being of shaped
iron plates, thus allowing the two sashes to open inwards without interfering with
one another.
Each casement is formed with a beading g' at the side opposite to the hinge,
which when closed fits into a correspondingly shaped beading b, on the inner side
of the sliding sash, thus completely closing the aperture and preventing any
draught.
At the hinged side of the casement a beading 9 of another shape is used,
projecting into a groove 6' in the stile B. Locks H are fitted in the stiles B, Bí

page_text: and the bolt h can be shot either into a recess in the pulley stile A' or into a
recess in the casement G G₁ locking either the sliding sashes to the frame or the
casement to the sliding sashes. In the former case, the sliding sashes would be
prevented from moving up or down, while the casement can be opened for cleaning
or for other purposes, thus preventing the sliding sashes being moved while the
casement is open. The sashes can only be raised or lowered when the casement is
locked, the bolt always locking in one or the other direction. The sliding stiles
are not provided with cross or horizontal bars, the sashes being completed by the
casements. The light area will thus not be materially reduced.
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 :-
(1.) An improved window in which, within the ordinary sliding sash, is hinged a
casement saɛb, having a lock fitted to the sliding sash, with a bolt which projects
either into a recess in the casement or one in the window frame, locking the sashes
together and allowing them to be raised or lowered, or locking the sliding sash to
the frame allowing the casement to be opened, substantially as and for the purposes
specified.
(2.) An improved window, having hinged within the ordinary sliding sash, a.
casement, with lock fitted to the sliding sash with a bolt, which can fix the sashes
together, or the outer one to the window frame the casement being furnished with
a beading around its edge fitting into a groove in or against a corresponding
beading on the sliding sash, substantially as described and shown, and for the
purposes specified.
(3.) In an improved window sash in which a casement is hinged in the ordinary
sliding sash, the employment of a special form of hinge formed of L shaped
plates, allowing the casement to be swung clear of the other parts substantially as
described and shown, and for the purposes specified.
(4.) In a window, the employment of a sliding slip fixing the end of the cord
and fitted to the sash stile, sliding in a suitably formed groove in the pulley stile,
thus concealing the cord substantially as and for the purposes specified.
(5.) The improved window sash constructed and operating substantially in the
manner described and illustrated in the accompanying drawings, and for the
purposes specified.
