PROVISIONAL SPECIFICATION.
Improvements in Railway and other Carriage Window Fasteners.
I WILLIAM PURDON of 5 Lambert Street, St. John's Wood, Hull in the
County of York, Commercial Traveller, do hereby declare the nature of this
invention to be as follows:-
The object of my invention is to hold or fasten railway and other carriage
windows at any height, so dispensing with straps, preventing rattling, and keeping
out the dust.
I employ an hinged or pivotted board or wedge, preferably at the bottom of the
window, this board or wedge comes against the window sash at an angle its edge
being of indiarubber or other suitable or pliable substance, so as to allow the
window to be freely raised, and yet on ceasing to raise the window the wedge grips
it and retains it in position, then by lifting the wedge the window is released and
falls. A spring of any kind keeps the wedge in its working position.

COMPLETE SPECIFICATION.
Improvements in Railway and other Carriage Window Fasteners.
I, WILLIAM PURDON of 5 Lambert Street, St. John's. Wood, Hull in the
County of York, Commercial Traveller, 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 :-
The object of my invention is to hold or fasten railway and other carriage
windows, at any height, so dispensing with straps, preventing rattling, and keeping
out the dust.
DESCRIPTION OF DRAWINGS.
Fig. 1 shows a side view partly in section of part of carriage window, with my
improvements applied.
Fig. 2 is a reduced plan view of carriage window with my improvements
applied.
Fig. 3 is a similar view to Fig. 1, in which a brake is employed.
Fig. 4 shows end elevation in section of carriage window, showing counter-
balance arrangement.
Fig. 5 is a front elevation in section of Fig. 4, with front of door left off, to
show counterbalance arrangement.
I employ a hinged or pivotted board or wedge A, hinged or pivotted to the
carriage door B, in any suitable position, this board or wedge comes against the
window sash or frame C at an angle, its edge D being of indiarubber, or other
suitable or pliable substance, so as to allow the window E to be freely raised, and
yet on ceasing to raise the window, the wedge grips it and retains it in any
required position; then by lifting the wedge, or pulling back its hook, the window
is released and falls.
A spiral or other spring F, keeps the wedge in its working position. An
ordinary rubber block may be placed at the bottom, for the window to drop upon,
and break its fall

page_text: Also a brake may be fixed under the wedge grip, consisting of a piece of
indiarubber or other suitable substance H, attached to a bracket J, at each side
of the window; so that after pulling back the wedge and releasing the window, the
brake comes in contact with each side of the window C, and so breaks its
-descent.
Or a counterbalance may be employed see Figs. 4 and 5, consisting of a
weight L, attached to cords, wires, chains M, or the like, such cords being
attached to the bottom of each side of the window or slide C, and passing. over
suitable pulleys or runners N, attached to the frame of the door B, effectually
balances and prevents the window from being brought down violently, it being
almost noiseless.
•
Any other suitable means of breaking its descent may be used.
A stop or guard K prevents the pivotted or hinged wedge from damage by
violent usage.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
-claim is :-
1. In railway or other carriage windows, the use and employment of a hinged or
pivotted wedge A, of any suitable shape, (for dispensing with straps) for holding
up the windows at any required height, and releasing them, as and for the purposes,
such as shown and described.
2. The use and employment of a hinged or pivotted wedge A. or its equivalents
for holding up and releasing the windows, for keeping out the dust and draught, in
the manner, as and for the purposes, such as shown and described.
3. The combination of the hinged wedge A with indiarubber piece D, spring F,
stop K, with or without brake G, or the counterpoise, in the manner, and for the
purposes, such as shown and described.
