Improvements applicable to Railway Carriage and other Windows.
We CHARLES LEIGH CLARKE of Weaste Road Weaste Engineer JAMES
MASON of Elton Bury Engineer, and JOHN LEIGH of Brown Street Manchester
Gentleman, all in the County of Lancaster, do hereby declare the nature of this
invention to be as follows:-
This invention relates chiefly to the windows of railway and other carriage doors
and consists of an improved method of and apparatus for raising, lowering, and
securing the same.
For this purpose I provide the outer edge of the sash at each side of the inner
face, with a waved rack made of india rubber, or other suitable material, and to the
door stile at each side I attach by pivots a flap which extends across the door, and
being weighted and being pivoted at its inner edges has a tendency to fall outwards
and rest against the sash frame.
The glass or window is raised in the usual manner either by means of a strap or
by a projecting finger piece ou the inside and as the waved projections of the racks
on the frame pass the outer edge of the flap it falls from one to the other in a
noiseless manner, and upon releasing the window in any position the outer edge of
the flap comes under the projections of the india rubber racks and immediately
holds the window frame and prevents it from falling.
When the window is raised to the top, the flap falls underneath the bottom of
the frame, and holds it up..
When it is desired to lower the window, either from its closed or partly closed
position, all that is necessary is to raise up the flap by means of a button provided
for that purpose and the window will then descend by its own weight. It can of
course be "eased " down by the strap or by the finger piece in the usual manner.

COMPLETE SPECIFICATION.
Improvements applicable to Railway Carriage and other Windows.
We CHARLES LEIGH CLARKE of Weaste Road Weaste Engineer, JAMES
MASON of Elton Bury Engineer, and JOHN LEIGH of Brown Street Manchester
Gentleman all in the County of Lancaster, 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 chiefly to the windows of railway and other carriage doors
and consists of an improved method of and apparatus for raising lowering and
securing the same.
Our invention will be readily understood from the following description on
reference to the accompanying sheet of drawings on which
Fig. 1 is a sectional elevation and Fig. 2 a front view of a railway carriage
door with our improvement applied thereto and Figs. 3 and 4 are similar views
showing a modified form of our invention.
We provide the outer edge of the window sash a at each side of the inner face
with a waved rack 6 see Figs. 1 and 2 made of india rubber or other suitable
material and to the door style c at each side we attach a flap d which extends

page_text: across the door and is so pivotted às seen at d* that it has a tendency to fall
outwards by its own weight and rest against the sash-frame a.
The glass or window a' is raised in the usual manner either by means of a strap
or by a projecting finger piece a' on the inside and as the waved projections of the
racks on the frame pass the outer edge of the flap d it falls from one to the other
in a noiseless manner, and upon releasing the window in any position the outer edge
of the flap d comes under the projections of the india rubber racks and immediately
holds the window frame and prevents it from falling.
In some cases we propose to modify the above construction as shewn on Figs. 3
and 4 and to let the racks b into the window sashes a. In this case the said racks
may be formed by metal or other plates 6 with slots or holes 6 cut or formed
therein and we make corresponding notches in the sashes a and we line the upper
side of the recesses so formed with india rubber or other similar material, and in
this case we provide the flap d with a projection or ratchet tooth d' at each end
which runs over the rack b on each sash a when the window is raised, and locks it
in any desired position.
In both the modifications shown when the window is raised to the top the flap d
falls underneath the bottom a' of the frame and holds it up, and thus it will be
seen that the flap d supports the window a' in every position.
When it is desired to lower the window, either from its closed or partly closed
position, all that is necessary is to raise up or pull inwards the flap d by means of a
button or loop d² provided for that purpose and the window a¹ will then descend by
its own weight; c* are india rubber stops (see Fig. 4) to lessen the shock'sustained
by the window when it falls to the bottom of the door. It can of course be "eased."
down by a strap or by the finger piece a³ in the usual manner.
-
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The improvement in railway carriage and other windows consisting in the com-
bination of a weighted flap pivotted to the fixed style and a rack at each side of the
sash frame the said flap serving to support the window in every position substan-
tially as hereinbefore described and illustrated by the annexed drawings.
