PROVISIONAL SPECIFICATION.
Improvements in Doors and Windows for Railway and other
Carriages.
1, TOм BATTY, of North View, Drighlington, in the County of York,
Decorator, do hereby declare the nature of this invention to be as follows:-
:―
This invention relates to improvements in doors and windows for railway and
other carriages, and particularly to that type of window in which a counter weight
is provided below to balance it and hold it in any position.
For this purpose I arrange the weight in the usual way to slide between guides
fixed below in the interior of the door casing or the casing below the window and
these vertical guides are preferably placed away from the centre nearer the hinged
side of the door. The weight is supported by a cord or band or its equivalent
attached to a cylinder mounted in suitable bearings above the weight. A projection
is provided on the underside of the window frame which when the window is raised
extends below the said cylinder and a cord or band or its equivalent is wrapped
around a second cylinder rigidly attached to and concentric with the first cylinder
but of a suitably larger diameter. The cords and weights are so arranged that
when the window is put down the cylinders are revolved thus drawing up the
weight but it will be evident that owing to the smaller diameter of the cylinder
upon which the weight cord is wound the traverse of the weight will be propor-
tionately shorter and consequently the weight will require to be heavier than the
window to balance it. Helical grooves may be cut in the cylinders to receive the
cords.
A projection or knob or its equivalent is formed on each side of the top rail of
the window frame in order that it may be raised either from the inside or the
outside. And to enable the window to be lowered from either side a hole for the
fingers is made through the lower rail of the frame. This hole is preferably faced
or surrounded by metal and to close it a thin metal partition is placed therein
preferably jointed or pivoted below and so arranged that its upper edge is free to
be pushed from either side to the other so as to leave a comparatively broad
bearing for the fingers. This improvement is also applicable to other sliding
carriage windows. The metal facing may be continued down below the window to
form the above mentioned projection to which the cord is attached.
To prevent the fingers of passengers being caught or trapped between the door
and the door post or frame I employ on one or both sides a spring guard or false
frame hinged or loosely attached to the interior of the door post with its edge
projecting more or less into the door way. The spring guard practically prevents
a passenger laying hold of the frame and in case the door is closed when the
fingers are upon or hold of the guard the guard readily gives under the pressure
and no injury is done. The guard also forms a draft excluder and may be lined
with felt or the like.

I, TOM BATTY. of North View, Drighlington in the County of York,
Decorator, 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 doors and windows for railway and
other carriages, and particularly to that type of window in which a counter weight
is provided below to balance it and hold it in any position.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents an elevation of the inside of a railway carriage door as well
as the side frame upon the hinge side of the door. The panelling below the
window is omitted to more clearly show the application of my improvements.
Figure 2, represents a sectional plan of the same on the broken line a b
Figure 1.
Figure 3, represents a vertical section on the broken line y z Figure 1.
Figures 4, 5 and 6 represent views of detail on a larger scale hereinafter
referred to.
'
To carry out my invention I arrange the weight A in the usual way to slide
between vertical guides B, B fixed between the middle and bottom cross rails C
and C2 of the door. The weight A is supported by a cord or its equivalent D
attached to the cylinder E mounted in bearings F, F secured in the top of the
guides B, B.
A projection G is provided on the lower rail H of the window-frame which
projection when the window is raised extends below the said cylinder and a cord or
its equivalent D' is connected by one end to the bottom of the projection G and is
wound around a second cylinder E2 which is rigidly attached to and concentric
with the cylinder E but of a suitably larger diameter.
It will be readily understood that when the window is put down the cord D
attached to it causes the cylinders to revolve thus drawing up the weight but
owing to the smaller diameter of the cylinder upon which the cord D supporting
the weight is wound the traverse of the weight will be proportionately shorter
than that of the window and consequently the weight will require to be heavier
than the window to balance it. Helical grooves e are cut in the cylinders to
receive the cords D and D².
A projection J is fixed to each side of the top rail H' of the window-frame in
order that it may be raised from either inside or outside. To facilitate lowering
the window from either side and afford a broad bearing for the fingers a hole K is
made through the lower rail H of the window-frame and a thin metal partition L
is fitted in this hole (see Figures 4, 5 and 6). The lower edge of the partition lies
in the groove M formed in the metal lining N along the bottom of the hole whilst
the upper edge is free so that the plate may be readily pushed by the fingers from
either side to the other within the limits allowed by the metal lips O, O formed
along each side of the top and the lips P, P formed upon the metal lining Qat
each end of the hole. The metal facing G on the inside is preferably continued
down to form the projection G. A piece of sheet india-rubber R is placed behind
the metal top lining S of the bole and its edge R³ projects a little way downwards
along each side so as to form a cushion for the upper edge of the plate and prevent
the rattle that might otherwise be caused by the vibration.

page_text: To prevent the fingers of passengers being caught or trapped between the door
and the door-post I hinge the guard U to the door-post W by the hinges V, V and
arrange it to project a little way over the door. The spiral springs X, X lying in
recesses Z in the door-post have their inner ends attached to cross pins a and their
outer ends passed through the guard and secured by the small nuts d and are
arranged to keep the guard normally against the door-post. The spring guard
practically prevents a passenger laying hold of the door-post and in case the door
is closed when the fingers are upon or hold of the guard the guard readily gives
under the pressure and no injury is done. The guard also forms a draft excluder
and may be lined with felt. A similar guard may be fitted to the other door-post.
The corners of the posts are preferably rounded to leave more room for the
fingers.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination with a carriage window having a downward projection on
the underside, of the double cylinder E, E', the weight A and the cords connecting
them, substantially as herein shown and described.
2. The combination with a carriage window having a finger hole through the
frame, of the loose partition L fitted therein, substantially as herein shown and
described.
3. The combination with a carriage door of the spring guard U fitted to one or
both side frames of the door, substantially as herein shown and described.
