Improvements in Fittings for Railway Carriage and other Sliding
Windows.
I, JOSEPH INGRAM, of 5 Lechmere Road, Willesden Green, London N.W..
Railway Clerk, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-.
The object of my invention is to effect improvements in fittings for railway..
carriage and other sliding windows, for the purpose of facilitating the operations.,
of raising, lowering and retaining the same in any required position.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is an elevation (partly in section) of the inside of a railway carriage door.
fitted in accordance with my invention.

Fig. 2 is a transverse sectional elevation of the upper part of the same. door,
and Fig. 3 is a similar sectional elevation of the middle and lower parts of the
same door, drawn to a larger scale.
I divide the ordinary garnish rail into two parts 4 and 5; the rail 4 being fitted
to the garnish rail 5, or its equivalent, by means of hinges 6, in such a manner that,
it may pivot upon its binges from a nearly vertical position to the inclined position
shown in Fig. 3.
The pivoted rail 4 is fitted with a thumb piece 7, and the fixed garnish rail 5 is
similarly fitted with a finger piece 8.
away
By applying the thumb and finger to the pieces.7 and 8 the rail 4 may be drawn
from the position shown in Fig. 3, its motion towards the vertical being
limited by its contact with the hand rail 9. 10 is one of two ordinary rubber pads,
which press against the window sash and prevent its rattling, when quite closed, as
shown in the figures. These, pads also retain the window at any required height,
when partly open. The hand rail 9 is useful in enabling a passenger to support
himself on entering and leaving a carriage.
When the window is entirely closed, as shown, it is held in that position by the
contact of the catch 11 with the upper edge of the pulley box 20 fitted on the
rail 4, the catch 11 being fixed to the window sash. On applying the hand to
the pieces 7 and 8, the rail 4 is caused to leave contact with the catch 11, and the
window falls down by gravity until it rests upon the fixed buffers 12, unless
arrested in its fall by the pads 10.
13 is a metallic plate sliding in grooves 14. This plate nearly counterbalances
the weight of the window. 15 is a cord (preferably of catgut). One end of this
cord is fixed to a bracket 16 attached to the underside of the window sash; the
cord is carried over a pulley sheave 17 in the box 20, and down to the plate 13.
This arrangement of weight 13 and cord 15 serves the double purpose of balaucing
or nearly balancing the window, and of keeping the rail 4 in an inclined position
with sufficient force to enable the pads 10 to hold the window in various open
positions, or partly open positions, as required, without the use of springs.
18 is the ordinary lift plate fitted to the inside of the window frame, in addition
to which I also fit an outside lift 19, to enable the guard to close the window
from the outside, without having to open the door for that purpose.

page_text: In closing the window the operator lifts it by means of one of the lift plates 18
or 19, the rail 4 readily yielding to the upward motion. On removing the hand
the contact of the pads 10 with the window frame causes the former to grip and
suspend the window in an open or partly open position, as required.
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. In railway carriage and other sliding windows, the combination of means
and appliances substantially as and for the purposes hereiubefore described and
illustrated by the drawings.
2. In fittings for railway carriage and other sliding windows, the combination of
a garnish rail or its equivalent divided into two parts 4 and 5, the rail 4 being
hinged or otherwise pivoted above the rail 5; the rail 4 being fitted with
pads 10 and a pulley sheave 17, sustaining the balance weight 13 and a portion of
the weight of the sliding sash, in such a manner as to cause the pads to grip the sash
frame; together operating substantially as herein before described and illustrated
by the drawings.
3. The combination with the means and appliances for supporting the sashes of
railway carriage and other sliding windows described, of a metallic plate 13 sliding
in grooves and arranged to partially balance the weight of the sliding sash,
substantially as herein before described and illustrated by the drawings.
4. The combination, with the fittings for railway carriage and other sliding
windows herein described, of a hand rail 9, substantially as and for the purposes
herein before described and illustrated by the drawings.
5. The combination with the fittings for railway carriage and other sliding
windows herein before described, of an additional lift plate 19, substantially as
and for the purpose herein before described and illustrated by the drawings.
