Improvements in Railway and other Carriage Doors and Windows.
CHARLES LEA, Bank Villas, Church Street, Silverdale, North Staffs, County
of Stafford, Tailor, do hereby declare the nature of this invention to be as
follows: :-
My present invention relates to railway and other carriage windows and doors,
and the object thereof is to construct the said doors and windows in such a manner,
that the sliding portion or window is actuated by a weight & pulleys, instead of the
leather strap &c. as now in use.
The said weight, pulleys &c., to be contained within the lower half of the door,
which is constructed in the usual way outside (and does not interfere with the
general appearance of the carriage) but the inside of the door is provided with a
second and smaller door, which is hinged to the stile or main frame of the door
proper, and is provided with a spring lock on the other edge, such lock may have
The use of such
one or more catches, and is actuated with one key in the centre.
small door is to facilitate the general fixing or repairs of the said weight, pulleys,
&c., such weight to work in a horizontal position, and is attached to the sliding
light or window by chains of brass, antifriction metal, or any suitable material,
which pass over pulleys attached or fixed in any suitable way to the stiles or main
frame of the door proper, and has a hole drilled, cast, or otherwise provided, of an
oblong form on the under side of the weight and of square proportion at the top (to
prevent the sticking of the weight on the conducting rods) and about 1 in. from each
end, to receive a conducting rod, of iron, steel, antifriction metal, or any suitable
material, such conducting rods to prevent the collision of the weight and window,
as the weight traverses about of the length of the window, the said conductors to
be secured to the bottom rail of the main door frame by a plate into which the
conductor is secured, and at the top, to the middle rail of the said framing in the
same way, such middle rail to be removable, and fixed by screws, or any suitable
means, to facilitate the fixing, repairs &c., of the said conductors.
The said weight to be heavy enough to overcome any friction that may arise
from the sliding of the window in the grooves, and also the weight of the said
window when glazed and complete, so that the natural descent of the weight will
cause the window to rise. The action of the said weight to be under the control of
a brake contained in a box or recess provided immediately above the top of the
small door inside, the outward lid or covering of such recess to be removable and
fixed with screws &c., to facilitate the fixing, repairs &c. of the said brake, such
brake to consist of a piece of wood or iron &c. covered with india-rubber, leather,
or any other suitable material, and to lie in a horizontal position across the window,
and of such a length that it will cover as much as possible of the frame of the
window, at each end, and to be pressed against the said window by one or more
spiral springs, and to be under the control of a knob or handle passing through the
centre of the lid or cover afore said. The neck or spindle of such knob to contain
a projecting stud working against an inclined or bevelled face, or boss, which upon
the knob being turned will cause the permanent locking and unlocking of the said
brake, or may contain a ratchet arrangement which will secure the same result, by
the pressure and release of the said knob, or may contain a screw, which upon the
knob or handle being turned will secure or release the brake at any given point,
the pressure of the brake in each case to bring the window into close contact with
a lining of india-rubber, leather, or any suitable material, contained in the outside
of the groove in which the window slides, thereby preventing the entrance of any
draught &c., and also to stop the window at any required position.

page_text: Also in the construction of the sliding light or window, the stiles and bottom rail
are securely framed together, but the top rail is removable and is fixed by screws,
to facilitate the removal of the glass and reglazing of the same, which glass is
simply slipped into a groove and does not require any putty or fixing by beads &c.

COMPLETE SPECIFICATION.
Improvements in Railway and other Carriage Doors and Windows.
I, CHARLES LEA, of Bank Villas, Church Street, Silverdale, North Stafford-
shire, 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 :-
My invention for "Improvements in Railway and other Carriage Doors and
Windows," relates to the constructing of the same, and in such a manner that the
sliding portion is controlled by a weight, in connection with pulleys, and parts
therewith and thus dispense with the strap and mode hitherto employed for raising
and lowering the same.
And in order that this my said invention may be more fully understood I shall
now proceed more particularly to describe the same, and for that purpose I shall
refer to the several figures on the sheet of drawings hereunto annexed the same
letters of reference indicating corresponding parts throughout all the figures.
Fig. 1 is a view in elevation (front) from inside of a railway carriage door with
sliding window, actuated or controlled according to my invention.
Fig. 2 is a plan view of same.
Fig. 3 is a view of same side elevation.
Fig. 4 is a view of same vertical section.
Fig. 5 is a view of same, horizontal section, on line A, B, Fig. 1, to
larger scale.
ณ
Fig. 6 is a view of same horizontal section on line C, D, Fig. 1, to a
larger scale.
a is the door with window b, c is the inside door at the lower half of a, hinged
at c, d is the weight provided with the rollers d¹ d' and d' acting as guides to
facilitate the ascent and descent of d, d' d' being at the ends of d and near the sides
of a, and d² being in the centre of d and working in the groove e in the door c.
To the weight d, at ff are affixed the pulley chains g g which pass over the
pulley wheels which work in fixed brackets 'the ends of said chains being
connected to the sliding window sash bat i. j is the buffer rod, provided with
buffer rollers at each end, k is the spring provided with a hole which passes
over the pull pin 1 and thereby held, the pressure of the spring k, against; the rod,
forces the rollers, against the sliding window sash and by its power the same
is held in any desired position, the spring k, in its action is controlled by the pull
knob which is in connection with the pull pin 7 and from the inside of the door a
of the carriage.
When the sliding window b is up and the door a is closed and occasion requires b
to be let down without opening the door a from the outside, recourse is had to the
knob m, which is connected by means of the pin n¹ jointed at n² to the lever n and
this is secured to the rod o (which is supported and works in the brackets) which
is provided with a claw lever p the action of release of the sliding window is by
the pull of this knob m, is the same as described of l.
The groove in which 6 slides is packed with india rubber or other yielding
material, to exclude draught and damp, or water as in the case when the window is
being washed, the effect being produced by the pressure obtained thereon by
spring k.
When the sliding window b is at its highest position the said spring k

page_text: causes the lower part of 6 to overlap the chamfered edge of the front of a as shewn
at r, Fig. 4.
The sliding window 6 is lowered by means of the plates by hand and against the
resistance of the weight d which rises, and remains there by the power of the
spring and parts in connection therewith as above described, but upon the release
of k, by the action of l' or m, the window will rise until the said lor m is released
when the said window will be again fixed and at any position.
It will be understood by the above and by referring to the drawings that the
"buffer" rod; and the spring k and their component parts are secured to the
"garnish" rail and this can be removed readily, as the door c, can be opened, for
the repairing or the adjusting of the above parts.
The above being my said invention I wish it to be observed that I do not limit
myself to the precise details as shewn on the sheet of drawings, but I may vary or
modify the same without departing from the principle of my said invention.
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 :-
1st. In "Improvements in Railway and other Carriage Doors and Windows," the
arrangement of a weight with rollers and chain on wheels connected to the sliding
window substantially as and for the purposes herein before described.
2nd. The arrangement of a "buffer" rod with buffer rollers, and a spring thereto
with actuating knobs inside and outside the door, substantially as and for the
purposes herein before described.
3rd. The arrangement of the chamfered edge to receive the lower part of sliding
window substantially as and for the purposes herein before described.
4th. The general construction, arrangement, and combination of the several
and respective parts, substantially as and for the purposes herein before
described in the foregoing Specification, and illustrated by the sheet of drawings.
