PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Opening and Closing Window
Sashes.
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:-
According to this invention I provide in the frame of the sash a suitable grouping
of pulleys so placed that cords can be passed over them and be attached to the
sash balance weights. By this arrangement when the cords are pulled downwards
from within a room the weights loose a sash balancing weight practically equal to
the force of the pull and the sash consequently drops from its closed position with
a velocity proportionate to the force of the pull exerted.
By attaching another cord to the usual sash-cord-groove and passing it over
other suitably placed pulleys in the frame or in the grouping of pulleys aforesaid
the sash can readily be drawn up to its full height by merely' pulling the ends of
the cords last mentioned as attached to the sash.

Improvements in Apparatus for Opening and Closing Window
Sashes.
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:-
According to this invention, I provide in the frame of the sash, a suitable
grouping of pulleys, so placed that cords can be passed over them and be attached
to the sash balance weights.
By this arrangement, when the cords are pulled downwards from within a room,
the sash balancing weights lose an amount of weight practically equal to the force
of the pull, and the sash consequently drops from its closed position with a velocity
proportionate to the force of the pull exerted.
By attaching another cord to the usual sash cord groove, and passing it over
other suitably placed pulleys in the frame or in the grouping of pulleys aforesaid,
the sash can readily be drawn up to its full height, by merely pulling the ends of
the cord last mentioned as attached to the sash.
And in order that my said invention may be more clearly understood, I will now
proceed to describe the same with reference to the drawings accompanying this
Specification, in which
Fig. 1 shews a back elevation of the pulley stile representing the position of the
extra pulleys fitted in the sash frame,

page_text: Figs. 2, 3, 4, and 5 shew views of the said pulleys and supporting pieces detached,
drawn to a larger scale,
Fig. 6 is a front view of the window frame, drawn to smaller scale than that of
Fig. 1.
The same letters of reference are employed in all the views to denote the same
parts.
a shews the balance weight, b the sash, c, c¹ ordinary weight pulleys, d, e, f, g, are
extra pulleys, carried on the supporting piece h, m is another extra pulley carried
on the piece n. Over the pulleys f, g, m passes a cord o fastened to the sash b and
provided with a handle P, and over the pulleys d, e passes a cord k, which is fastened
to the weight a and is provided with a handle l.
The action is as follows :—
On pulling the handle 1, the balance weight a will be drawn up, and supported
by the person pulling such handle-consequently the sash b will fall by its own
weight, which will be no longer counterbalanced by the sash weight a. On pulling
the handle p, the sash will rise-being drawn up by the cord o.
The above arrangement is fitted to each side of the sash, and may be fitted, if
desired, to the lower sashes of windows, in which case, pulling the cords attached
to the corresponding balance weights would close the sash.
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 :-
1. The improvements in apparatus for opening and closing window sashes,
substantially as set forth.
2. In window sashes, the employment of cords or the like, passing over pulleys,
said cords being attached to the counter balance weights, for the purposes set
forth.
3. In window sashes, the employment of cords or the like, passing over pulleys
and attached to the sash stiles, at or near the same place at which the ordinary
weight sash cords are affixed, for the purpose of raising sashes, substantially as
set forth.
