PROVISIONAL SPECIFICATION.
Improvements in the Method of Hanging Window Sashes.
I, ARTHUR PICKARD Engineer 48 Franklin Road Harrogate do hereby declare
the nature of this invention to be as follows:-
My present invention is intended to simplify the construction of windows by
causing the two sashes to act as a balance for each other thus dispensing with
independent balance weights, this is accomplished in the following manner.
The window frame may be constructed in the ordinary way having suitable
grooves provided for the sashes to travel in; a cord, wire, or chain, is attached
to each side of the bottom sash and carried upwards to the top of the window
frame where is affixed in a suitable position a pulley over which the cord runs and
then descends to the top of the upper sash and is fixed thereto.
The upper sash is now suspended by these cords, and if the upper and lower sashes
are of equal weight they will balance each other, and the act of raising one will
cause the other to descend or vice versa.
If one sash should be lighter than the other it may be weighted to obtain a
balance, or one sash may be purposely made heavier than the other in order to
obtain automatic closing or opening of the windows, in which cases provision may
be made for causing the sashes to remain in any desired position by bolts,
catches etc.
If it is desired to make the top sash travel at a slower rate than the bottom one,
this may be accomplished in the following manner.
If the top sash is desired to descend at half the rate, at which the bottom one
ascends an additional pulley is fixed to each side of the upper sash the descending
cord is then passed under this pulley and carried upwards again to the top of the
window frame, and finally attached thereto; in this case it may be found necessary
to weight the upper sash in order to obtain an approximate balance. To facilitate
the outside cleaning of the glass in the bottom sash, the grooves in which it runs
may have the upper half of its inner guide rails removed so that when the bottom
sash is raised to the top of the window frame it may be swung inwards at the
bottom, and then drawn down again clear of the guide rails and within reach of
the operator.

Improvements in the Method of Hanging Window Sashes.
1 ARTHUR PICKARD Engineer 48 Franklin Road Harrogate 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 present invention is intended to simplify the construction of windows, by
causing the two sashes to act as a balance for each other thus dispensing with
independent balance weights.
This is accomplished in the following manner. The window frame may be
constructed in the ordinary way, having suitable grooves provided for the sashes

page_text: to travel in, a cord wire or chain is then.attached to each side of the bottom sash
and carried upwards to the top of the window frame where is affixed in a suitable
position a pulley over which the cord runs and then descends to the top of the upper
sash to which it is attached.
The upper sash is now suspended by these cords and if the upper and lower
sashes are of equal weight they will balance each other and the act of raising one
will cause the other to descend or vice versa.
If one sash should be lighter than the other it may be weighted to obtain a
balance; or one sash may be inade purposely heavier than the other in order to
obtain automatic opening or closing of the windows, in which cases provision
may be made for causing the sashes to remain in any desired position by bolts
catches &c.
If it is desired to make one sash travel at a slower rate of speed than the other,
this may be accomplished in the following manner: If the top sash is desired to
descend at halt the speed at which the bottom one ascends, an additional pulley is
fixed to each side of the upper sash, the descending cord is then passed round this
pulley and carried upwards to the top of the window frame and finally attached
thereto, in this case it may be necessary to weight the upper sash in order to obtain
a balance.
To facilitate the outside cleaning of the glass in the bottom sash, the grooves in
which it runs may have the upper half of their inner guide rails removed, so
that when the bottom sash is raised to the top of the window frame it may be
drawn inwards at the bottom and then brought down again nearer the operator,
clear of the guide rails.
In the accompanying drawings
Figure 1 represents the window open for cleaning, the bottom sash has been
raised to the top and brought inwards over the top of the short guide rails or staff
beads and then drawn down nearer the operator.
Figure 2 represents a section of Figure 1.
Figure 3 represents a section of the window closed.
Figure 4 represents a method of arranging the pulleys when it is desired to make
one sash travel at a slower or faster rate than the other or when it is desirable to
make a small sash balance a larger one.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what 1
.claim is,
1. In windows where one sash is made to balance the other, the absence of the
upper part of the inner guide rails or staff beads, to allow of the bottom sash
when raised to the top of the window frame being drawn inwards for cleaning.
2. The arrangement of pulleys substantially as illustrated in Figure 4 the object
being to make a small sash balance a larger one, or to make one sash travel at a
slower or faster rate than the other.
