Advocate.]
An Improvement in Sash Holders.
I, SYDNEY FRANCIS GEDGE, of 23 Austin Friars, in the City of London,
Solicitor, do hereby declare the nature of this invention to be as follows:-
This invention relates to sash holders of the kind in which a roller, contained in
a recess cut in the edge of the sash frame, bears against the inclined face of a rubber
free to slide to a certain extent within the recess, so that, when the sash tends to
descend, the roller, descending along the inclined back of the rubber, presses the
rubber outwards against the window frame, exerting friction in the manner of a
brake, sufficient to prevent the sash from descending by its own weight, but not
enough to prevent it from being pushed down. According to this invention, the roller
is interposed between the inclined back of the rubber and a cradle which has ends
projecting outwards to form stops limiting the up and down movement of the
roller..

This cradle has attached to its back a spring consisting, preferably, of several
superposed plates like a carriage spring, the innermost plate of which has its ends
bent into semicircular shape with the round backs of the bends bearing against the
back of the recess in the sash frame. The rubber, which may be of wood faced
with metal, has a shoulder formed above the inclined part of its back, this shoulder
acting as a stop for the roller when the rubber is in the lowest position which the
depth of the recess permits it to take. A sash holder of this kind is especially
applicable to the windows of railway and other carriages, but it may also be applied
to sashes generally.

COMPLETE SPECIFICATION.
An Improvement in Sash Holders.
1, SYDNEY FRANCIS GEDGE, of 23 Austin Friars, in the City of London,
Solicitor, 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 :-
This invention relates to sash holders of the kind in which a roller, contained in
a recess cut in the edge of the sash frame, bears against the inclined face of a rubber
free to slide to a certain extent within the recess, so that, when the sash tends to
descend, the roller descending along the inclined back of the rubber presses the
rubber outwards against the window frame, exerting friction in the manner of a
brake, sufficient to prevent the sash from descending by its own weight, but not
enough to prevent it from being pushed down.
A sash holder according to the present invention is shewn in the accompanying
drawings,
Fig. 1 being a section shewing the position of the parts when the sash is being
raised, and
Fig. 2 an elevation shewing their position when the weight of the sash is
sunported

page_text: A is the rubber which is of T section having its back rib cut to form an incline B
and a shoulder C. The roller D is interposed between the inclined back B of the
rubber A and a cradle E which has ends projecting outwards to form stops limiting
the up and down movement of the roller D. The cradle E has attached to its back
a spring F consisting, preferably, of several superposed plates like a carriage spring,
the innermost plate of which has its ends G bent into semicircular shape with the
round backs of the bends bearing against the back of the recess in the sash frame
in which it is lodged. The rubber A which may be of wood faced with metal, has,
as shewn, the shoulder C formed above the inclined part B of its back, this shoulder
acting as a stop for the roller D when the rubber is in the lowest position which the
depth of the recess permits it to take as shewn in Fig. 1. A sash holder of this
kind is especially applicable to the windows of railway and other carriages, but it
may also be applied to sashes generally.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:
In a sash holder, in combination with the rubber A having an inclined back B
and the roller D, the cradle E and spring F substantially as herein described.
Dated this 10th day of October 1893.
