PROVISIONAL SPECIFICATION.
An Improved Device for Supporting Sliding Windows or Shutters
such as those of Railway or other Carriages when Partly Open.
I, GEORGE LANCELOT EYLES of 2 Delahay Street, Westminster, S.W., Civil
Engineer, do hereby declare the nature of this invention to be as follows:
My invention has reference to an improved device for supporting sliding windows
or shutters such as those of railway or other carriages when partly open for which
purpose I provide at each side of the window or shutter and frame within which the
same is adapted to slide up and down a rack and a hook like tooth such that the
hook like teeth or projections will when the window or shutter is raised or lowered
to the desired position engage each with a tooth of the rack at the corresponding
side of the window or shutter so that the latter will be supported in such a manner
as not to be liable to rattle; in some cases a spring or springs may be used to assist.
in preventing rattling.

COMPLETE SPECIFICATION.
An Improved Device for Supporting Sliding Windows or Shutters
such as those of Railway or other Carriages when Partly Open.
I, GEORGE LANCELOT EYLES of 2 Delahay Street, Westminster, S.W., Civil
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 :-
My invention has reference to the improved device illustrated in the accompanying
drawing and hereinafter described for supporting sliding windows or shutters such
as those of railway or other carriages when closed or partly open in such a manner
that they shall not be liable to rattle.
Fig. 1 shews in vertical section part of a carriage door with window having my
invention applied thereto.
Fig. 2 is an elev. tion at right angles to Fig. 1.
Fig. 3 is a view similar to Fig. I shewing a louvre shutter in lieu of a window.
Fig. 4 is an elevation at right angles to Fig. 3.
A (Figs. 1 and 2) is the window;-A¹ (Figs. 3' and 4) the shutter ;-B is the
frame within which the window or shutter is adapted to slide up and down. At
each side of this frame there is a rack plate of peculiar form; it has a straight
edge C with wedge-shaped notches C' at intervals. At each side of the window
sash or shutter there is attached a tooth D so formed as to bear at its inner inclined
side on the lower inclined surface of the wedge-shaped notch C' with which it may
for the time being be engaged, the construction and arrangement being such that,
as shewn in the drawing, the flat surface of the window sash or shutter will be
brought against the straight surfaces of the rack plates at each side of the door or
window. As will be evident the window or shutter is adapted to slide up and
down; and the hook like teeth or projections thereof will when the window or
shutter is raised or lowered to the desired position engage each with the tooth
forming the bottom of one of the wedge shaped notches C¹ of the rack at the
corresponding side of the window or shutter so that the latter will be supported in
[Price od 1.

be used to assist in preventing rattling as indicated at E.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that I do not
claim broadly and generally the application to the window frames and sashes of
railway and other carriages of racks and hooks, but what I do claim is:―
The improved device illustrated in the accompanying drawing and hereinabove
described for supporting sliding windows or shutters such as those of railway or
other carriages when partly open, the construction and arrangement being such that
as shewn in the drawing, the flat surface of the window sash or shutter is brought
against the straight surfaces of the rack plates at each side as set forth.
