PROVISIONAL SPECIFICATION.
An Improved Method of Hanging Window-sashes.
ARTHUR ALEXANDER GOVAN Wood Merchant 15 Renfield Street Glasgow do
hereby declare the nature of this invention to be as follows:-
The window cords are carried from the front sash up to and over grooved pulleys
fixed near the tops of the side channels of the lower sash, but said pulleys not as
usual inserted in the side channels, but fixed on the surfaces thereof, with their
grooves at right angles to the upper sash. After passing over the pulleys the cords
are carried down to points of attachment to the upper sash and there terminate and
are fixed. The cords are attached to one or other sash by a couple of springs
which may be set with a degree of tension to maintain a measure of strain on the
cords. By this arrangement the one sash acts in counterpoise to the other and side
boxes and weights are dispensed with. In combination with above and where
desired a swivelled or movable strap of wood or metal may be supplied to cover
over the lower opening when it is wished to have only the upper sash open.

COMPLETE SPECIFICATION.
An Improved Method of Hanging Window-sashes.
1, ARTHUR ALEXANDER GOVAN, of 15 Renfield Street, Glasgow, in the County
of Lanark, North Britain, Manufacturer, 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 :-
My invention relates to an improved method of hanging window sashes, and
consists in so arranging the sashes that the one acts as a counterpoise to the other,
and so dispenses with the side weights presently employed. To effect this, the
window cords, which are non-stretching, are carried from the front sash up to and
over pulleys fixed near the top of the pulley styles, and are carried to the upper sash
at a point a little underneath the pulley so that when the lower sash is raised, the
upper sash is simultaneously lowered.
In order that my invention may be properly understood and readily carried into
effect, I have hereunto appended one sheet of drawings showing the side view of a
window.
A is the lower sash; B the upper sash: C the pulley style; F the pulley, which
is fixed on the face of the style C at a slight angle to it, so that it will carry the
non-stretching cord d clear of the parting bead g. The one end of the non-stretching
cord d is attached to a small metal plate e, which is screwed to the lower sash A.;
and the other end is attached to a similar plate el fixed to the face of the upper
sash B, so that as the lower sash A is raised, the upper sash B is simultaneously
lowered thus both the top and bottom sashes are open at the same time.
It is to be understood that although only one side of a window is shown in the
drawings, the same arrangement is applied to the other side.
If the window sashes are not of an approximate weight to each other, a little
metal may be added to the lighter one as required.
When it is desired to have only one of the sashes open, a strap of wood G, or
other material may be hinged or otherwise attached at either top or bottom of the
window casing to cover such opening.

tion and in what manner the same is to be performed, I declare that what I
claim is:
The method of hanging window sashes by causing the one sash to act as a
counterpoise to the other, and by the use of non-stretching cords, substantially as
described and illustrated in the accompanying sheet of drawings.
