PROVISIONAL SPECIFICATION.
An Improved Method of Hanging Sliding Window Sashes.
I WILLIAM STABLES INGLE of Green Gate Apperley Bridge in the County of
York, Joiner and Builder, do hereby declare the nature of this invention to be as
follows:-
This invention consists in hanging Window Sashes in such a manner that one half
of the Window balances the other: that is to say when one half is raised or lowered
the other half moves the same distance in an opposite direction.
To carry ont this Invention I employ a grooved pulley working in a suitable case
bracket, which I fix to the top of each internal side of the Window Frame, the centre
of the pulley being mid-way between the two side Window-sash frames. Over these
grooved pulleys I pass a cord or chain, one end of which is fixed to each top side sash
frame and the other end to each bottom side sash frame thus when the top side sash-
frame is being lowered, the bottom sash frame is raised and vice-versa.

COMPLETE SPECIFICATION.
An Improved Method of Hanging Sliding Window Sashes.
I, WILLIAM STABLES INGLE, of Greengates, Apperley Bridge, in the County of
York, 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 :—
This invention relates to improvements in the method of hanging sliding window
sashes when two sashes are mounted in one frame, and it consists in banging said
window sashes in such a manner that one sash balances the other; that is to say, that
when one sash is raised or lowered the other sash is so connected to it that it moves
the same distance in an opposite direction.
To carry out this invention I employ two grooved pulleys mounted in suitable case
brackets or boxes one of which I attach to the top of each internal side of the window
frame the centre of the pulleys being midway between the two sashes. 1 pass a cord
or chain over these pulleys and one end of each cord is fixed to the top of opposite
sides of the top sash and the other end of the cords or chains are secured to the same
sides of the bottom sash, thus when the top sash is being lowered the bottom sash is
raised and vice-versa.
To more fully illustrate my invention reference is made to the accompanying sheet
of drawings forming a part of this specification in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1 is an elevation of a window frame with the sashes partly open and arranged
in accordance with my invention.
Figure 2 is a vertical section of the same.
Figure 3 is a side elevation of the window frame with the side removed but leaving
the pulley at that side in position.
A pulley A mounted in the box or case B is secured to the top of each side C of the
window frame, aud metallic cords D pass over such pulleys and their ends are
respectively attached to the hooks E and F let into the sides of the top and bottom
sashes G and H. The hooks F are provided with screwed shanks a so that such hooks
may be adjusted vertically in respect to the lower sash by means of the nuts b for the

page_text: purpose of adjusting the length of the cords and insuring both sashes being
together. The upper sash G has a portion J cut away at each top corner to all
top of such sash to pass the pulley cases B.

To facilitate cleaning and repairs the staff beads K and K'are divided and a
is hinged to the window frame so as to be opened as represented at K fi are 1
to allow the sashes to be removed. It is also necessary to remove one of the
parting beads L to take out the top sash. Buttons or tongues M are provided to
secure the beads K and K' when closed.
A draught flap N is hinged to the bottom of the window frame which flap
may be turned into the position represented by the dotted lines figure 2 for the
purpose of excluding the draught beneath the lower sash when the sashes are partly
open as represented.
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 what I claim is:
1. In a window frame provided with two sashes, the arrangement herein described
in which the sashes are connected together by cords or chains passing ove pulleys
and thereby balance each other, substantially as herein shown and deser and
illustrated in the accompanying drawings.
•
2. The combination with a window frame having two sashes arranged to balance
each other, of hinged staff beads and a draught flap, substantially as herein shown and
described.
