COMPLETE SPECIFICATION.
An Improved Arrangement for Balancing Window Sashes.
TOM HOLMES TURNER, 66, Grafton Street, Leeds, in the County of York, 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 consists of an improved arrangement for balancing window
sashes. The distinctive features of this arrangement consists in making the upper
window sash act as a counterbalance to the lower sash, and vice versa.
A cord or chain is fixed in front or inserted at the side of the upper and lower
window sashes at corresponding corners.
Each cord or chain passes over a suitable pulley, which may be fastened to the
side or the top of the window frame.
In raising the lower window sash, the upper sash will descend and remain at any
position.
By this arrangement the ordinary balance weight and the space required for it
at each side of the window frame are dispensed with.
This invention is also applicable to the opening and closing of shutters or doors,
by the modification of placing the pulley at a distance above the top side of the
opening to allow the upper side of the shutter or door to rise above and clear of
the opening, and by making the cord or chain sufficiently long, to permit the lower
half getting down below the opening.

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 arrangement of self balancing window sashes or shutters as hereinbefore
described and as shown by the accompanying drawings.
