Improvements in connection with Window Lifts and Windows for
Railway Carriages and Road Vehicles, applicable also to other
Windows.
ROBERT HYDE, Derbyshire House, Darnall Sheffield in the County of York
Engineer do hereby declare the nature of this invention to be as follows:-
According to this invention I arrange a lock and make suitable connections to
secure the window lift and draught excluder bar (as shown in Patent No. 13182
year 1891) to the window frame which slides up and down in a railway carriage
or cab.
°
In carrying out my invention in practice I make a lock of suitable shape and size
having a pivoted lever, at one end of the lever, a spring is used, any suitable shape,
to keep lever in locked position.
The bolt and catch is on the other end of the lever and is made in shape to be
self locking. To release the lock pressure is applied to the back of the lever to
compress the spring and release the catch. The lock and connection can be used
with a draught excluder or not, the advantage of the lock is that it can be released
in an instant by pressing the lever with a nail or pricker thereby enabling repairs
to be done readily.
The lock can be used with a window lift and falling or moveable garnish rail.
The lock connection is made between the window frame and window lift to prevent
the lift from sticking in bottom of window recess and also to prevent the lift being
pressed out of right position.

1. ROBERT HYDE Derbyshire House, Darnall, Sheffield in the County of York,
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:-
This invention relates to improvements connected with windows or sliding
shutters or louvres or the like used in railway carriages or other doors. According
to this invention I arrange a lock and make suitable connection to secure the
window lift and draught excluder bar (as shown in Patent No. 13,882, 1891) to
the window frame which slides up and down in a railway carriage or cab. In
carrying out my invention in practice I make a lock of suitable shape and size
having a pivoted lever. At one end of the lever a spring is used any suitable
shape to keep lever in locked position. The bolt and catch is on the other end of
the lever and is made in shape to be self locking. To release the lock, pressure is
applied to the back of the lever to compress the spring and release the catch or

page_text: connection. The lock and connection can be used with a draught excluder or not.
The advantage of the lock is, that it can be released in an instant, by pressing the
lever with a rail or pricker, thereby enabling repairs to be done readily. The
lock can be used with a window lift and falling or movable garnish rail. The lock
connection is made between the window frame and window lift to prevent the lift
from sticking, or jamming in bottom of window recess, and also to prevent the lift
being pressed out of right position.
The object of this improvement is to provide a more expeditious method of
connecting and disconnecting windows, and window lifts used in railway carriages,
and other doors such as my window lift No. 14,073 Oct. 1/1888 it is also
applicable to Patent No. 13882 Aug. 18th 1891. A screw turn is not required
to make the connection, there being no screws to displace to disconnect the window
from window lift, or to connect same which is very important when repairs have to
be done quickly at stations without taking carriages out of made up trains.
In order that my said invention may be more fully understood the mode in which
I prefer to carry it into effect is illustrated on the accompanying sheet of
explanatory drawings which are marked with figures and letters of reference
corresponding with those in the following description thereof.
Fig. 1 plan of lock.
Fig. 2 plan of pivoted lever.
Fig. 3 side elevation showing pivoted lever.
Fig. 4 front elevation showing lock in position on bottom part of window frame
with connection to window lift giving space for draught excluder bar.
Fig. 5 section on A. A.
Fig. 6 front elevation showing connection without draught excluder bar.
Fig. 7 section on B B. showing catch or connection in locked position.
Fig. 1 shows plan of lock with pivoted lever a in closed position which has a
pin B passing through it and the sides of the box c. A small spring d (any
suitable shape by preference spiral) is made to keep lever in closed position as
shown. The projecting piece e on lever is bevelled on under side to allow catch
or connection (Fig. 4) to be pressed into position when projecting piece e, is
forced through hole y and makes the connection between lock and catch or con-
nection. The catch is secured to the top of window lift I as shown. It can be
fixed centrally or near each end. One or more locks can be used to each window.
The spring H can be used or not, with catch or connection f a split pin K and a
washer is used to secure catch ƒ to top of window lift I when draught excluder bar
is used.
Fig. 6 shows catch revited to top part of window lift I for use without draught
excluder bar.
Fig. 7 is a section on B B showing catch or connection in locked position. The
fence plate L supports window in top or closed position as shown in Fig. 7.
To release the catch or connection, all that is necessary is, to press a nail or
pricker against back of lever a, inserting it in hole M which is made opposite
pivoted lever a which will compress spring d, and cause lever to move on
pin B, sufficient to withdraw projecting piece e on end of lever out of
hole g and liberate the catch or connection f. It will be understood that the
connection and disconnecting of the window lift or sash holder and window or sash
can be done immediately when desired.

The parts of my apparatus can be made of any suitable material and is so made
and arranged that the windows or louvre, can be used to existing arrangements
there being no projections on bottom of window frames.
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
1. The novel and special construction and application of connection as shown in
Figures 1 to 7 of the accompanying drawings constituting improved connecting.

page_text: apparatus for windows or sashes or louvres and the use thereof in railway carriage
doors or windows or other doors, the same being substantially as hereinbefore
described or set forth.
2. The lock mechanism connected with and arranged for the aforesaid combina-
tion for connecting and disconnecting as shown in Figures 1 to 3 inclusive of the
accompanying drawings and substantially as hereinbefore described or any equivalent
modification thereof.
