PROVISIONAL SPECIFICATION.
Improvements in Sliding Window Sashes.
RICHARD JONES, 6, Croydon Street, Bryanston Square, London, W., Landau
and Coach Furniture Fitter and Bicycle Engineer do hereby declare the nature of
this invention to be as follows:-
To prevent the shaking and rattling of glass frames or sliding windows in every
description of vehicle, or window sashes, I insert in the frame a metal box which
contains a roller cradle spring. This spring works on a pivot in the centre of the
box, with a metal or india rubber roller working at both ends.

COMPLETE SPECIFICATION.
Improvements in Sliding Window Sashes.
I ROBERT JONES of 6 Croydon Street, Bryanston Square, in the County of
London, Landau and Coach Furniture Fitter and Bicycle Engineer, 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 sliding sashes with means or apparatus
for supporting or sustaining them in any desired position without rattling in the
window frame to which they are fitted.
The invention is adaptable to all kinds of sliding sashes but is specially
serviceable for the sashes of railway carriage and other vehicle windows.
In carrying my invention into practice, I provide the sliding sash on one or on
both sides with a recess in which is secured a spring or springs carrying a friction
roller or rollers which normally projects beyond the recess and bears against the
contiguous sides of the window frame.
The accompanying drawings shew my invention as applied to an ordinary double
sash window frame; Figure 1 is an elevation partly in section; Figure 2 is a
section taken on the line A B of Figure 1; and Figure 3 is an enlarged section of
the sash. The same letters of reference are used to denote the same or
corresponding parts in all the figures. Referring to the drawings C represents a
recess or box formed in the side of the sash and D is the spring which is secured in
the said recess at E. The spring carries two friction rollers F one at each end
which are preferably secured between cheeks formed by bending up projecting
pieces on the sides of the spring. The tension of the spring is adjusted so as to
cause the friction rollers F to project beyond the outside edge G of the sash thus
causing them to bear against the contiguous face of the window frame H. The
Bash is provided with suitable stops J against which bear the tail pieces d of the
spring which prevent the spring from coming completely out of the recess C when
the sash is removed from the window frame. Figure 3 shews in full lines the
position of the parts when the sash is out of the window frame; the dotted lines
shew the position of the parts when the sash is in the window frame. It will be
understood that the power of the springs D will depend upon the weight of the
sash, the vibration to which the window frame is likely to be subjected and the
more or less ease with which the sash is required to work.
fit each side of
the sash with a spring device such as above described but for ordinary purposes I
find it is sufficient to fit the device on one side only and to secure a strip of leather,
I
may

other side as shewn in Figure 1.
I do not wish to confine myself to the details of construction shewn in the
drawings, as these may be varied without departing from the nature of my
invention.
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. Means or apparatus for supporting sliding sashes in any desired position in a
window frame consisting of a spring secured on the outside of one, or of both side
rails of the sash and carrying a friction roller or roilers which bears or bear against
the contiguous side or sides of the window frame substantially as and for the
purpose herein before set forth and illustrated in the accompanying drawings.
2. My improvements in sliding window sashes substantially as described and
illustrated in the accompanying drawings.
Dated this 1st day of August 1893.
