Improved Means and Apparatus for Raising, Lowering, and Retain-
ing the windows of Railway Carriages and other Vehicles, and
Draught Excluder for same.
I HENRY DEARDEN of 5 Lombard Street, King Cross, Halifax, Yorkshire Joiners'
Foreman, 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 improved means for raising lowering and retaining
the windows of railway carriages and other vehicles and means for operating an
automatic draught excluder for same.
In carrying out the first part of my invention for raising lowering and retaining.
the said windows I employ an extending and collapsing system of levers commonly
known as lazy-tongs which are operated by a bell-crank lever a connecting rod and
suitable spring.
To the said bell crank lever is attached a combined handle and catch which said
catch engages in a V notched segment secured to the lining or boarding of the inside
of the carriage door. In carrying out the second part of my invention I secure to the
window frame bearings in which work freely by suitable connections the draught
excluder which is operated by means of bars or strips of wood or other suitable
material which are secured to the inner side of the lining or boarding of the outside
of the carriage door and against which said bars or strips the draught excluder
slides.
In order to enable my invention to be fully understood I will describe the same by
reference to the accompanying drawings.
Fig. 1 is a view of a Railway Carriage door, the window being represented as closed
and the outer lining or boarding removed in order to shew more clearly the method
of working the window frame.
Fig. 2 is a like view shewing the window open.
Fig. 3 is a view of the inside of a carriage door shewing the V notched segment and
bell-crank lever handle.
Fig. 4 represents part of the bell-crank lever (to which is attached the combined
handle and catch) and a sectional view of the V notched segment secured to the lining
or boarding of the carriage door.
Figs. 5 & 6 represent the V notched segment.
Figs. 7 to 10 inclusive are detail views in plan & elevation of a nut and
bracket.
Figs. 11 to 16 inclusive are detail views in plan and elevation of the combined
handle and catch.
Fig. 17. is an elevation of part of a window frame with the draught excluder
attached.
Fig. 18 is a plan of same.
Fig. 19 is a side elevation shewing position of draught excluder when the window
is closed and

page_text: Fig. 20 is a side elevation shewing position of draught excluder when the
window is open or partially open. Similar letters of reference indicate similar
parts
A is the window frame to which is attached a bracket a connected by a stud or
pin b to one end of the extending and collapsing system of levers or lazy-tongs the
opposite end of the lazy-tongs being attached by a pin c to a nut or fixing d secured
to the lining or boarding of the carriage door. e is the hell-crank lever which works
freely on a stud or pin f the said stud or pin f being fixed in a second nut or fixing d
also secured to the lining or boarding of the carriage door. Near one extremity of
the bell-crank lever e is a stud g upon which one end of a connecting rod h works
freely the opposite end of the connecting rod h works freely on a stud or pin i secured
to the centre of the lazy-tongs.
Near the other extremity of the bell crank lever e is attached a stud or pin j
upon which is a bracket k with a stud or pin upon which one end of an
elastic, rubber, or other suitable kind of spring m is attached the said spring m
being attached at its other end to a second bracket attached to a third nut or
fixing d.
One portion of the bell-crank lever e is bent as at n Fig. 4. to allow its
passing through a semi-circular slot in the lining or boarding of the carriage door
and the V-notched segment O. Near the end of the bell crank lever is attached
the combined handler and catch 8.
When it is necessary to raise or lower the window frame A the operator takes hold
of the handle and presses the thumb button or capt which compresses the spring u
and releases the catch s by then moving the handler in the direction required it
will be obvious that the window frame A can be raised or lowered at will, and set at
any position by releasing the thumb button or cap t and allowing the catch s to
engage with the V notches of the segment o.
The draught excluder a' may be made of brass, sheet iron or other suitable material
with suitable bearings w which work freely on pins or studs x attached to the window
frame A. On the inner side of the outer lining or boarding of the carriage door I
attach bars or strips y of wood or other material against which the draught excluder a¹
slides when the frame A is raised or lowered, when the window is closed the draught
excluder a¹ assumes the position as shewn in Figs. 17 and 19 and when the window is
open or partially open it assumes the position shewn in Figs. 18 and 20.
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 hereinbefore described method and improved means for raising retaining and
lowering the windows of railway carriages and other vehicles.
2. In combination in apparatus for raising retaining and lowering railway carriage
and other vehicle windows a freely extending and collapsing system of lazy-tongs
with a bell crank lever and combined handle and catch substantially as hereinbefore
described.
3. In combination in apparatus for raising retaining and lowering railway carriage
and other vehicle windows an automatic draught excluder connected to the sash
frame, substantially as herein before described and illustrated in the accompanying.
drawings.
