PROVISIONAL SPECIFICATION
Improvements applicable to Railway and other Carriage
Windows
I WILLIAM WRIGHT of Ashfields, 751 Hyde Road, Gorton Manchester, in the
County of Lancaster, Commercial Traveller, do hereby declare the nature of this
invention to be as follows:-
This invention consists of a simple appliance to be adapted to railway and other
carriage windows for the purpose of enabling the same to be raised and lowered or
fixed in any desired intermediate position.
The invention consists principally of two horizontal sliding bolts the outer ends
of which project through openings at each side of the sliding window sash, near
to the top so as to lock into suitable holes or recesses formed in the fixed frame
or style at each side near to the top or bottom, and also at intermediate positions
between the two. The inner ends of these sliding bolts overlap and are provided
with teeth or projections which interlock with other teeth or projections from a
central boss which is so mounted as to revolve in holes or bearings in the metallic
casing of the apparatus. This boss is fitted with a handle or knob projecting
inside the door of the carriage, whereby the boss can be turned so as to withdraw
both the sliding bolts into the casing and to release the sash window, and allow
it to be lowered when required.
The two sliding bolts are each fitted with a coiled spring having a constant
tendency to thrust or pull the bolts outwards whenever the knob is released.
The upper side of the projecting end of each bolt is bevilled like an ordinary
door catch so that the window can be raised without turning the knob and when
the bolts come opposite to the holes in the frame they will be shot outwards by
the springs and hold the sash in position. It is only when the sash is to be
lowered that the knob is required to be turned, but the same knob also serves to
raise the window sash.
Dated this 9th day of May 1896.

COMPLETE SPECIFICATION.
Improvements applicable to Railway and other Carriage
Windows.
I WILLIAM WRIGHT, of Ashfields, 751 Hyde Road, Gorton, Manchester, in the
County of Lancaster, Commercial Traveller, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
This invention consists of a simple appliance to be adapted to railway and other

page_text: carriage windows for the purpose of enabling the same to be raised and lowered, and
fixed in any desired intermediate position.
The nature of the said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to the
annexed sheet of drawings and the following explanation thereof.
The invention is applicable both to the top rail of a sash window such as
are used for the doors of carriages and also to the bottom rail of saloon windows.
Fig. 1 on the annexed drawings is an elevation Fig. 2 a longitudinal section and"
Fig. 3 a transverse section of my improved apparatus as applied to the top bar of a
sash window such as are fitted in the doors of railway or other carriages.
The invention consists principally of two horizontal sliding bolts a and b the
outer ends of which project throngh openings formed in the metal casing e one
at each side near to the top of the sliding window sash d (the upper part of which
only is shown).
The outer ends of these bolts a and bare bevilled at the top, so as to lock
into suitable recesses a formed in the fixed frame or style at each side, near to
the top or bottom, and also at intermediate positions between the two.
The inner ends of these sliding bolts a and bare bent so as to overlap and are
provided with teeth or projections e which interlock with other teeth or projections
formed on a central boss which is so mounted as to revolve in holes or bearings
in the metallic casing e of the apparatus (see also enlarged detached view of these
parts Fig. 4).
This boss is fitted with a handle or knob y projecting inside the door of the
carriage and also with a similar one outside, by either of which the boss can
be turned partially so as to withdraw the sliding bolts a and b simultaneously into
the casing and to release the sash window and allow it to be lowered or raised
to the position required.
The two sliding bolts a and b are each fitted with a coiled spring 4 or other suitable
spring or springs having a constant tendency to thrust or pull the bolts outwards
whenever the knob or handle g is released.
r
I prefer to make the metallic casing which encloses the apparatus of a piece of
sheet metal bent into an inverted trough shape (see Fig. 3) so as to be light and
capable of being fitted onto the sash without cutting away the woodwork; the parts
carrying the movable portions of the apparatus being fixed therein by screws or
rivets.
The upper side of the projecting end of each bolt a and b is bevilled or rounded
like an ordinary door catch so that the window can be raised without turning the knob.
or handle g and when the bolts a and b come opposite to the holes in the fixed frame
or style they will be shot outwards by the spring or springs and hold the sash in
position.
It is only when the sash is to he lowered that the knob or handle g is required to
be turned, but the same knob also serves to raise the window sash.
To adapt this improved apparatus to sash windows which do not fall down into a
casing, such for example as the side windows of saloon carriages all that is necessary
is to bevil off the projecting ends of the bolts in the opposite direction, and to turn
the apparatus upside down and to fit the same underneath the bottom rail of the sash
as shown at Fig. 5.
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 :-
. In apparatus for raising lowering and fixing railway and other carriage windows,
the combination with a hollow metal casing, adapted to be fitted to the top or
bottom rail of the sash, of two sliding bolts thrown outwards by a spring or springs
and capable of being withdrawn by partially turning an external knob or handle fitted
to a central boss having teeth or projections gearing with teeth or projections on the
inner ends of the said sliding bolts, the said knob or handle being also adapted

page_text: to be used for raising or lowering the window sash when the bolts are withdrawn
substantially as herein before described and illustrated by the drawings annexed.
Dated this 9th day of February 1897.
