PROVISIONAL SPECIFICATION.
Improved Method of Opening and Closing Carriage Windows.
WALTER HENRY TYLER, of 127, North Street, Brighton, Refreshment Contractor.
I do hereby declare the nature of this invention to be as follows;-
This invention has for its object the easy opening and closing of carriage windows
and of maintaining same in any desired position by means of a cord or chain
attached to a wheel revolved by means of a handle. When the desired position.
is attained the window is fixed in position by the handle which works on a swivel
joint being stopped against a peg.
This invention is more particularly applicable to the windows of railway carriage
doors.

Improved Method of Opening and Closing Carriage Windows.
I, WALTER HENRY TYLER, of 127, North Street, Brighton, in the County of
Sussex, Refreshment Contractor, 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:-
My invention relates to an improved method of and means for raising and
lowering the windows of railway, private and public carriages, the object of which
it to effect such raising and lowering or opening and closing of such windows
more easily than hitherto, and to provide means whereby the said window may
be automatically arrested and held in any position between closed and opened by
the mere cessation of exercising the means for operating the same.
In order that my said invention and the way in which I propose carrying the
same into effect may be fully and clearly understood, reference is hereinafter made
to the accompanying sheet of drawings, of which
Fig. 1 is an inside elevation of a railway carriage door to which my said invention
has been applied, Figs. 2 and 3 being similar views with the inside panel removed
for the purpose of showing my said invention and the manner in which it operates,
the former illustrating a partly raised window locked in that position, while the
latter illustrates a partly raised window unlocked and about to fall by the action
of gravity alone, and I have assumed that these views while referring to railway
carriage doors will serve to make clear the application of my invention to the
sliding windows of private and other road carriages.

page_text: In carriage doors of the type in question it is usual to arrange that the window
frame A slides vertically in grooves formed in each of the sides of the frame of
the door B, the said frame A when lowered passing down between the outer panel C
and the inner panel 1) of the said door.
For the purposes of my invention I mortice or otherwise fix, to the frame of the
door B, and between the outer and inner panels CD, and between the sash A and
the panel D, one or more wood or other brace pieces E or E and F, upon the latter
of which I mount by the means of a screw G. a metallic or other wheel H in the
form of a grooved pulley, the back face of which has formed upon its periphery
ratchet teeth J, as shewn in Figs. 2 and 3, in which views the front face of the
said wheel is broken away in order to show the said teeth. The space between the
front and back faces of the wheel H is adapted to receive one end of a chain, cord
or wire K, preferably the former as shewn, the opposite end of K being pivotally
connected to the lower end of the sash A, so that when H is rotated in the direction
of the arrow in Fig. 2 the said sash would be raised to the height desired, as illus-
trated by Fig. 3, and lowered if the direction of rotation of the said wheel be
reversed.
Upon the brace piece E, I provide a lever or handle L, pivotally connected thereto
at a point M, one end of the said lever being provided at one end with a projecting
hand hold such as N, which projects through a suitably shaped hole O in the
panel D, (Fig. 1) sufficiently to be held between the thumb and forefinger, and so
be raised or lowered, the opposite end of the said lever being in loose connection
with the upper end of a bell crank lever P, pivotted at R, and having a nosing S
and projection or lug T, with the latter of which engages a suitable spring V, the
tension of which serves to keep the nosing S engaging with the ratchet teeth J of
the wheel H, as at Fig. 2.
A. hole is formed in the inside panel D to receive the outer face of the wheel H,
which is flush with the said panel, and thereat receives any suitable form of handle
preferably such as W, by means of which the said wheel may be rotated from the
inside of the carriage.
The before mentioned loose connection between the lever P and the lever L may
be by that of a pin or peg upon the former with which the latter may engage, but
for preference I form an eye X upon the upper end of P through which may freely
pass the small end of the lever L. The manner of operation is as follows.
To raise the window A from its position in Fig. 1, the wheel H would be rotated
in the direction of the arrow Fig. 2, thereby winding upon the boss of the said
wheel the chain or the like K, and so raise the said sash A, and during such rais-
ing of A the nose of the lever P would be kept in contact with the ratchet teeth J
by the tension of the spring V, so that whenever the hand is taken from the
handle W the window would be retained in whatever position raised by the said
lever P engaging with the teeth J but if a slight pressure, in a downward direction,
be imparted to the projection N on the lever L the opposite end of L would be
raised, and would raise the lever I', and so place its nose S clear of the ratchet
teeth J as at Fig. 3. when the the window A would immediately fall by its own
weight, and thus unwind the chain or the like from the wheel H, but the said
downward travel of A may be arrested at any point by simply removing the finger
from the hold N, when the nose S of the lever P would immediately again make
contact with the teeth J by the action of the spring V. and so arrest the wheel H.
In order that the sudden stoppage of A, when allowed to fall to its lowest position,
may not be violent, I provide at the lower end of the frame B a block of rubber,
such as Y, or any other form of elastic or resilient material or surface, or any form
of spiral or plate spring for attaining the same end, and I may find it convenient
or desirable to provide blocks of rubber or other form of spring or springy surface
or surfaces upon the outer edges of the sides of the frame A, or the grooves in B
in which it slides, in order to lessen the rapidity with which the said frame would
otherwise fall, and the probable noise or rattle that might arise therefrom.

Having now particularly described and ascertained the nature of said
invention and in what manner the same is to be performed I declare that what I
claim is:-
In an improved device for raising and lowering carriage windows, the com-
bination of a wheel H with handle W, and having a ratcheted surface J, and spring
lever P engaging with said ratchets, with lever L adapted to be depressed and
release P from J, the said wheel H by its rotation in one direction serving to raise
the sash A by the means of a cord, chain or wire K, substantially as described
and shewn.
Dated this 10th day of September 1898.
