PROVISIONAL SPECIFICATION.
Improvements relating to Window Sashes.
I JOSEPH BUATIER of 85 Rue de Pompe, Passy, Paris, in the Republic of
France, Gentleman, do hereby declare the nature of this invention to be as.
follows:-
The object of this invention is to provide for the raising and lowering of window
sashes with greater facility than heretofore and the invention consists in the
manner of hanging the sashes, whereby this object is effected.
In carrying out my invention, I secure, preferably to the lower edges of the
sash, a plate which projects through a slot in the side of the weight box. To
these plates, the sash lines are attached.
The sash lines pass from one of these plates, say 1, upwards over a pulley,
across the top, over a second pulley, downwards under another pulley to the plate,
say 2, on the other side. From this plate 2, the line continues upwards over
pullies at the top and down the other side to one end of a weight, then from the
other end of the weight downwards under a pulley to the plate 1.
Each sash is thus
The lines of the other sash are arranged in a similar manner.
provided with one weight only, and both sides of the sash being attached to the
weight, it is evenly balanced, and can be raised and lowered by pressure at any
part of the sash.
The sash lines are thus entirely enclosed in the weight boxes.

COMPLETE SPECIFICATION.
Improvements relating to Window Sashes.
I JOSEPH BUATIER of 85 Rue de la Pompe, Passy, Paris, in the Republic of
France, Gentleman, 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 :—
The object of this invention is to provide for evenly raising and lowering
window sashes, no matter at what point in the sash the necessary pressure may be
applied, and the invention consists in the manner of hanging the sashes, whereby
this object is effected.
In carrying out my invention, I secure, preferably to the lower part of the side
bars of the sash, a plate which projects laterally through a slot in the side of the
weight box, and to these plates the sash lines are attached.
One of these sash lines, which may be enclosed within the weight box, will pass
from the plate on one side, round suitable pullies, across the top of the window, to
the plate on the other side, and thence back again to one end of a weight, and then
from the other end of the weight to the first named plate, or vice versa.
The lines of the other sash are arranged in a similar manner.
Each sash is thus
evenly balanced, and can be raised and lowered by pressure at any part of the
sash other than the centre.
In the accompanying drawing,
Fig. 1 is a front view of a window and frame arranged according to my
invention, the covers of the weight boxes, etc., being removed; and
Fig. 2 is a side elevation, with the side of one of the weight boxes removed.

B is the lower sash, and B¹
A is the window frame, which is constructed in
ordinary window frame, with weight boxes A' at
recessed lintel A'; or, in other words, a box frame.
the upper sash, which are of ordinary construction, and work in the grooves
formed by the usual beads on the frame.
To the sash frames, one on either side, are secured plates a a¹, which extend
laterally from the sash, and project through slots. (Fig. 2) in the sides of the
weight boxes A¹.
The position of these plates a a¹ on the sash frame, is practically of no
importance, but it is preferred to place them in the positions shewn in the drawing,
as the slots will then be covered by the sash frame when the windows are
closed.
CC are the sash lines, and D D¹ are the weights.
Referring now to the sash B, the sash line C is attached to the plate a, and
passes downwards and round a pulley 1, then upwards over a pulley 2, across the
top of the window, and over the pulley 3, and downwards to the plate a', to which
it is attached. The line next passes downwards round a pulley 4 to one end of the
weight D, and from the other end of the weight D, over pulleys 5 and 6, to the
plate a again.
By this arrangement, both sides of the sash B will be connected together, and
to the weight D, so that at whatever portion of the sash pressure is applied to
raise or lower it, the pressure will be distributed all over, and the sash will move
evenly. The upper sash B' will be connected by lines C₁ to the weight D', the said
sash lines passing over a corresponding number of pulleys, say, 7, 8, 9, 10, 11, 12,
arranged in a different plane to the first named set, but mounted on the same
axles, with spacing pieces or collars, to keep them the requisite distance apart.
Instead of connecting each sash to a weight, I may connect the two sashes
together, so that they will counter-balance one another, and will move in opposite
directions at the same time.
Or the window sashes may be supplied with the ordinary weights, the equalising
lines being applied so as to ensure the sash moving evenly as before explained.
When the lines are employed as equalising lines only, as, for instance, when
applying them to windows at present in use, may adapt the pulleys outside the
frame, fitting the plates a. a¹ to either the top or bottom rail of the sa h, cranking
them so that they pass outside the bead. The lines may be enclosed within a
casing.
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. Distributing the pressure applied at any part other than centrally, to raise or
lower a window sash by means of sash lines arranged substantially as herein shewn
and described.
2. Connecting the opposite sides of a window sash together, and to a weight, or
the other of a pair of sashes, by means of sash lines arranged substantially as and
for the purpose herein set forth.
3. Hanging window sashes substantially as herein shewn and described.
