PROVISIONAL SPECIFICATION.
Improvements in Window-sash Apparatus.
We, MATTHEW BUTCHER, of 40 Noble Street, Sunderland, in the County of
Durham, Insurance Agent and ARCHIBALD CAMERON, of 53 Frederick Street,
Sunderland aforesaid, Draper, do hereby declare the nature of this invention to
be as follows:-
Our invention relates to window-sashes of the ordinary sliding form, and the
object of our invention is the construction of apparatus and its combination with
such sliding sashes, to take the place of the pulleys, cords and weights, ordinarily
employed therewith.
The apparatus forming the subject of our invention is constructed substantially
as follows.
One, or more metal frames, of suitable form, are sunk into recesses on the outer
edge of each side of the sash. And each such frame is provided with a roller
journalled therein, or free to rotate upon a pin fixed in the frame.
These rollers are formed of some suitable elastic material, thus they may, for
example, be made wholly of rubber, or of metal, or wood faced with rubber.
They bear against the inside of the window frame, and project beyond the sash
to an extent that will ensure sufficient compression between the frame and the sash
of the elastic material of the roller, to cause enough friction to retain the sash in
any position to which it may be raised or lowered.
If desired, suitable means or devices may be combined with the apparatus, to
adjust the degree of projection of the rollers from the sash, in order to conform to
reduction in size by wear, or to alterations in the dimensions of the sash, or frame
from shrinkage, or other cause.

We, MATTHEW BUTCHER, of 40 Noble Street, Sunderland, in the County of
Durham, Insurance Agent and ARCHIBALD CAMERON, of 53 Frederick Street,
Sunderland, aforesaid, Draper, 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 :-
Our invention relates to window sashes of the ordinary sliding, or other like
form, and the object of our invention is the construction of apparatus and its
combination with such sliding sashes, to take the place of the pulleys, cords and
weights, or like devices, ordinarily employed therewith.
In the accompanying sheet of drawings, forming part of this Specification and
in which similar letters of reference denote similar parts throughout,
Fio is front elevation and

Fig. 2 is a side elevation of an ordinary double sliding window sash, having our
invention applied thereto.
Figs. 3 and 4 are elevations, at right angles to each other and to an enlarged
scale, of the apparatus, forming the subject of our invention, which is combined
with the said sashes.
Figs. 5 and 6 are similar views of a modified form of the said apparatus, and
Fig. 7 is a detached view of a roller, forming part of the said apparatus.
A is an upper and B a lower sliding window-sash, of ordinary construction.
C is a metal frame of suitable form, such for example as those shewn in Figs. 3
and 4 or 5 and 6, and sunk into a recess on the outer edge of the side of the sash.
Holes D, D, are provided in the frame, so that it may be secured within the said
recess by screws, but any other suitable means may be employed for fastening the
frame therein. E is a roller contained within the frame, and F is a pin passing
through and secured in the sides of the frame, upon which the said roller is
journalled and free to rotate.
In Figs. 1 and 2, as shewn, two such frames and rollers are provided on each
side of the sash, but in small sashes, one on each side may in some cases be
sufficient, while in large sashes more than two may be employed, if necessary.
The rollers E are formed of some suitable elastic material, thus they may for
example be made wholly of rubber, as indicated in the drawings, with a central
tube or bush H to form a bearing for the pin F, or they may have a central part
of wood or metal, surrounded by a thick ring of rubber.
These rollers bear against the inside of the window frame, and project beyond
the sash to an extent that will ensure sufficient compression between the frame
and the sash, of the elastic material of the roller, to cause enough friction to retain
the sash in any position to which it may be raised or lowered.
If desired, suitable meaus or devices may be combined with the apparatus to
adjust the degree of projection of the rollers from the sash in order to conform to
reduction in size by wear, or to alterations in the dimensions of the sash, or frame,
from shrinkage, or other causes.
In the case of sliding windows in railway carriages, or other vehicles, a series
of slight indentations may be formed in the sides of the frame into which the
rollers on the sash can spring, and thus ensure the said sash being securely held
at any height required, and so obviate any tendency to drop, due to the vibration
of the carriage, or vehicle.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is:-
1. In a window sash of the class described, the combination therewith of rollers
of elastic material, substantially as and for the purpose herein set forth.
2. In a window sash of the class described, the combination therewith of rollers
surrounded by elastic material, substantially as and for the purpose herein set
forth.
3. In a window sash of the class described, the combination therewith of metal
frames C, containing rollers E formed wholly or partly of elastic material and
journalled on pins F, held within said frames, substantially as and for the purpose
herein set forth.
4. In a window sash of the class described, the combination therewith of metal
frames C, containing rollers E, formed wholly or partly of elastic material and
journalled on pins F, and meaus for adjusting the position of said rollers relatively
to said sash, substantially as and for the purpose herein set forth.
Dated this 3rd day of December 1895.
