PROVISIONAL SPECIFICATION.
Improvements appertaining to Sashes and Doors for Railway
Carriages and other Vehicles.
We, ALBERT RHODES of Victoria Villas, Rickardshaw Lane, Stanningley
near Leeds, in the County of York, Manager, and CHARLES GILL of Spring
Valley Stanningley aforesaid, Engineer, do hereby declare the nature of this
invention to be as follows, that is to say :-
It consists of improvements appertaining to sashes and doors for railway carriages
and other vehicles, by the employment of which said sashes are suitably counter-
balanced and the means used for this purpose are rendered serviceable for operating
or regulating the positions of said sashes while the whole is cheaply produced and
may be readily applied.
In accordance with our invention we arrange the sash to slide in the framework
of the door as at present, however instead of the strap attached to said sash having
one end left to hang loosely for the purpose of operating or raising same, we
arrange this strap to pass firstly over a suitable guide roller or runner, mounted in
bearings attached to cross rail or frame of the door, then to pass under a similar
runner mounted upon a counterbalancing weight which has its edges formed to fit
guide-pieces fixed within the hollow part of the door, the outer end of this said
strap being finally taken and fixed in a suitable position or to a suitable part of
the framework of said door, so that it thus has one of its ends attached to the sash
while the other is attached to the door, by which means as said sash is moved up
and down the counterbalancing weight will be similarly moved but in an opposite
direction and only through half the space.
This counterbalancing weight occupies a position somewhat centrally in the door,
in which latter a slot is made so that an appropriately formed handle attached to
the weight may protrude through it. By this handle the weight and consequently
the sash may be operated so that the occupants may adjust same as desired
without leaving their seats, the only force required for performing such adjustment
being that which is necessary to overcome the friction of the operating parts
which is or may be regulated by suitable spring attachments so that any vibrations
of the vehicles will not cause the sash and weight to alter their positions.
As the doors and sashes of ordinary coaches, cabs and other road vehicles are
similar to those of railway carriages as far as regards the applications of our
invention it will be seen that we may with equal advantages make use of same in
connection with either or any of those vehicles.

Improvements appertaining to Sashes and Doors for Railway
Carriages and other Vehicles.
We, ALBERT RHODES of Victoria Villas, Rickardshaw Lane, Stanningley
Dear Leeds in the County of York, Manager, and CHARLES GILL of Spring
Valley, Stanningley, aforesaid, 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 certain improvements appertaining to sashes and doors
for railway carriage and other vehicles, and has for its object the regulation of the
position of the sash as required with the least amount of friction and wear and
tear, and consists in the arrangement and suspension of the sashes in such a manner
that, a sash may be readily moved up and down in the grooves of the door, and
there retained in the position by a weight exactly counterbalancing the sash, thus
avoiding the necessity of, as in other cases, the application of a brake to hold the
sash in any required position. The weight is placed in a cavity within the
door and is moved through a shorter distance by one half than that of the sash
itself.
In the accompanying drawings
Fig. 1 represents an elevation of a door suitable for a railway carriage.
Fig. 2 is a vertical sectional view of the same, and
Figs. 3 and 4 enlarged sectional details.
The sash A. is placed in grooves B. formed in the stiles of the door frame which
extend nearly the whole length of the door, and to the bottom portion of the sash
frame are secured brackets C. having a bar D. passing between the same, to which
is attached one end of a strap E. the other end being attached to a similar bar F.
suspended by brackets G. secured to the frame of carriage door.
Between the ends of the strap E. secured in the manner described, is suspended
the counterbalancing weight W. by a roller R. journalled in projections H. of said
weight which is placed in suitable grooves J. within the casement of the door, so
that it does not come in contact with the sash as it moves up or down in grooves B.
By suspending the weight W. in the manner described, the sash is counter-
balanced and the weight moved through less space by one half than that of the
sash, and by placing the strap E. in the position shown and described, it is out of
reach of being destroyed by the wilful damage of passengers so frequent in the
ordinary method. The sash is raised and lowered by means of a suitable projection
secured thereto in any convenient manner.
By arranging the sash to slide in the door in the manner described, there is no
space between the sash and door, as is the case when constructed in the ordinary
manner, into which lighted matches and the like may be placed and deposited in
the cavity in which the lower portion of the sash A. and weight W. slide, thus
reducing the liability of the door being set ou fire.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is,
A door with which is combined a sash A. supported by one strap E. attached to
the sash and door and provided with a weight W. arranged to work in one half of
that traversed by the sash.
