PROVISIONAL SPECIFICATION.
Improvements in and in connection with Sash Rollers.
I, ELIZA MILLS of 24 William Street East Greenwich Lady do hereby declare the
nature of this invention to be as follows:-
The object of my invention is to prevent sashes being jammed in their frames when
wet or swollen, and also to prevent them rattling when dry. For this purpose, I
fix the roller or rollers on a bed of brass or other metal, supported at each end by a
steel spring of sufficient strength, the whole being enclosed in a box of brass or other
metal, which I fit into the sash itself at the top and bottom of the sides. The working
of these rollers is as follows. When the sash swells, the roller or rollers, press against
the side of the sash-frame, the pressure forcing the roller into its box and thereby
compressing the spring. The sash shrinks, and, the spring being relieved, forces the
roller out, thus holding the sash tight in the frame.
In the case of heavy sashes, the use of my invention prevents them from jamming
in raising or lowering, as, working on rollers, they cannot jam.

SPECIFICATION.
Improvements in and in connection with Sash Rollers.
J, ELIZA MILLS of 24 William Street East Greenwich Lady 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, and
accompanying Drawing:-
-
The object of my Invention is to prevent window sashes being jammed in their
frames when wet or swollen and also to prevent them rattling when dry.
For this purpose I fix the roller or rollers, having a central pin or stud, on a plate
or bed of brass or other metal as in a bearing and capable of revolving freely therein
the said plate or bed being supported at each end by a steel or other spring of sufficient
strength-the whole being enclosed in a box of brass or other metal or material
which I fit into the sash itself at the top and bottom of the sides or
thereabouts.
The working of these rollers is as follows:-When the sash through variable
causes swells, the roller or rollers press against the sides of the sash frame, this
pressure causes the roller or rollers to be forced as in proportion into its box or
case thereby compressing the springs contained therein, but upon the sash shrinking the
springs become relieved and forces the roller or rollers out, thus holling the sash perfectly
tight in the frame. In the case of heavy sashes in particular the use of my Invention
will materially facilitate and prevent them from jamming, when required to be raised
or lowered, as worked on rollers it will be found impossible for them to jam.

The following figures have

reference to like or corresponding parts: A is the box or case containing the roller B,
which is pivotted by means of a pin or stud C, into a plate or bed D which is
kept in position by means of the coiled or other class of springs E, which in turn
bear upon the inner portion F, of the box or case A.
It will therefore be seen that the roller B, and movable bed plate C, and

page_text: springs E are respectively kept well in position in the box or chamber A and
always ready to act in manner referred to and not liable to get out of order.
Although I have referred to my method for fitting my improved sash rollers as to
the sashes of the windows I may in some cases prefer to fit same to the frames of the
windows instead.
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 use of a roller acting on a plate and springs within a box or case-substantially
for the purpose as hereinbefore illustrated and described.
