PROVISIONAL SPECIFICATION.
Improvements in Railway Carriage Windows and the like.
I, ROBERT DENNY Junr., of 26 Apsley Place, in the County of the City of
Glasgow, North Britain, Plumber, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in railway carriage windows and the
like, and has for its object to dispense with the use of the ordinary leather straps
and connections and at the same time to provide more efficient means for raising
and lowering the windows of railway carriages and other vehicles.
In carrying out my said invention I mount on the inside of the sash one or more
perpendicular racks into which I engage one or more suitably shaped or angled
catches, said catches being mounted on the hinged lower bar of the window or
door. I also provide the sash at its upper end with a suitable catch or handle.
Also in accordance with my invention, if desired, I may provide a catch or handle
and movable pin arrangement on the outside of the window sash or frame whereby
the window may be opened or closed from the outside.
The whole thus forms an efficient raising and lowering apparatus for vehicle
windows, in which the tendency of the windows to change position during the
vehicles movement is greatly prevented.

COMPLETE SPECIFICATION.
Improvements in Railway Carriage Windows and the like.
I ROBERT DENNY, Junr. 26 Apsley Place, Glasgow, Plumber, 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 railway carriage windows and the like,
and has for its object to dispense with the use of the ordinary leather strap and
connections and at the same time to provide more efficient means for raising and
lowering the windows of railway carriages and other vehicles.
But in order that my said invention may be more readily understood and easily
carried into effect I will proceed to describe the same with reference to, the
accompanying drawings in which
Figure 1 is an elevation and
Figure 2 a section shewing my improvements applied to the window of a railway
carriage door.
In carrying out my invention, I mount at each side of the sash A of the window,
the upright racks B into which the catches or pawls b engage, said catches being
mounted on the hinged or pivoted bar C of the door, the pins c forming the
pivots being shewn in dotted lines in the figures. The sash A at its upper end
is provided with a hooked finger portion D for raising and lowering the window.

page_text: The catches b on the bar C are kept in contact with the rack B by weighting
the top of the bar C by means of a strip of lead c. To lower the window all
that is required is to raise it a little by means of the catch D and pull the lower
bar forward by its knob or finger portion c², thus disengaging the catches b.
If desired a catch or finger portion may be provided on the outside of the
window sash or frame whereby the window may be opened or closed from the
outside, without the necessity of opening the door as is necessary with the ordinary
strap which has to be first unhooked or unbuttoned from the inside of the
carriage.
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
To raise and lower railway carriage and other windows, the arrangement of the
racks B upon the window sash, into which the catches or pawls b on the hinged
lower bar of the door engage, substantially as hereinbefore described and shewn in
the accompanying drawings.
