Improvements in Sliding Windows for Railway Carriages and

•
I, WILLIAM ROCHESTER PAPE of 36 Westgate Road in the City and County
of Newcastle on Tyne, Gunmaker do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in sliding windows for railway carriages
and similar vehicles.
To effect my purpose I propose to fit or attach on or in connection with the top
or bottom and by preference the latter of the window frame or sash one or a pair
of rollers which may be of or about the width of the sash and mounted at each
end in brackets or on arms attached for example to the corners of the frame or
Bash.
The rollers may consist of brass or other tubes or bars over which there may be
fitted india rubber or other equivalent tubes or coating and the external diameter
of such roller or rollers where a pair are used is intended to be sufficient to
give a working fit in or between the opposite sides of the window casing. or
casings.
Thus one roller so formed and mounted may fit the casing or two may be
similarly arranged so that when the window is drawn up or down the fitting or
friction of the rollers against each other or arranged as described between the
casings or frames will give sufficient frictional resistance to hold or suspend the
window in any desired positions while draughts through or up or in the casings will
be adequately prevented.
The rollers can thus revolve against each other or against the casing to support
the sash or window and to in like manner prevent the entry of dust or draughts
therethrough.

COMPLETE SPECIFICATION.
Improvements in Sliding Windows for Railway Carriages and
similar Vehicles.
I, WILLIAM ROCHESTER PAPE of 36 Westgate Road, in the City and County
of Newcastle on Tyne, Gunmaker, 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 improvements in sliding windows for railway carriages
and similar vehicles.
To effect my purpose I propose to fit or attach on or in connection with the top
or bottom and by preference the latter of the window frame or sash one or by
preference a pair of rollers which may be of or about the width of the sash and
mounted at each end in brackets or on arms attached for example to the corners of
the frame or sash.

page_text: The rollers may consist of brass or other tubes or bars over which there may be
fitted india rubber or other equivalent tubes or coating and the external diameter
of such roller or rollers where a pair are used is intended to be sufficient to
give a working fit in or between the opposite sides of the window casing or
casings.
Thus the rollers may be so arranged with regard to the casing that when the
window is drawn up or down the fitting or friction of the rollers against each other
or arranged as described between the casings or frames will give sufficient frictional
resistance to hold or suspend the window in any desired positions while draughts
through or up or in the casings will be adequately prevented.
The rollers can thus revolve against each other and against the casing to support
the sash or window and to in like manner prevent the entry of dust or draughts
therethrough.
I will fully describe my invention with reference to the accompanying drawings
in which Figure 1 shows a front elevational view illustrative of my improvements;
Figure 2 is an enlarged side view shown partly in section and partly in elevation of
the same; Figure 3 is a side view of a modification all as hereinafter described
and in the following description like marks of reference designate like parts.
Referring to Figures 1 and 2 of the drawings let S represent a window sash
and SS the sides of the casing in which it works. Connected to the sash as
shown are brackets or arms a which carry brass or equivalent bars or tubes a¹
adapted to revolve and over the latter india rubber or like flexible tubing a³ is
placed, the diameter across the pair of rollers so formed exceeding to the required
degree the internal width of the window casing so that the compression of the
tubing or coating as the case may be between the sides of the casing shall give
sufficient resistance to enable the window to be beld in any intermediate or other
position.
.
If only one roller was used instead of two as shown its revolution would
obviously be prevented by its contact with the opposite sides of the casing and
friction would be unnecessarily increased and therefore I do not recommend its
adoption.
The brackets on or in which the roller-carrying-bars are mounted may be
constructed as shown in Figures 1 and 2 or if required as shown in Figure 3
the arms A carrying the rollers may be free to swing or radiate on a pivot P
so that the centres of the rollers need not be at a determinate distance apart.
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 :-
―:
In sliding windows for railway carriages and similar vehicles the combination
with the window sash of india rubber or like flexible rollers adapted to support the
window in any required position by their contact with the casing, the several parts
being arranged combined and adapted for use substantially as and for the purposes
herein set forth.
