This invention relates to improvements in apparatus for raising and lowering
the sliding windows of railway and other carriages the object of the invention
being the production of an apparatus whereby the sashes can be easily and quickly
opened and closed by merely operating by the hand a handle or knob on the inside
of the carriage door or window.
In carrying out our invention the sash frame carrying the glass is made to freely
run up and down in grooves and guides as usual and the said sash frame is
counter-balanced by a spring or weight; along the bottom of the sash frame is a
slot in which runs a small wheel or runner block; the said wheel or runner block
is attached to the end of a radiating lever jointed at the other end to the side of
the sash box, and at a short distance from this joint there is jointed on the radiating
lever a link, which is connected at the other end to a crank on the spindle of the
knob or handle in such a manner that when the handle or knob having the crank
is turned, it communicates a motion to the radiating lever by means of the link,
and by means of the radiating lever a raising or lowering motion is given to the
sash frame according to the direction in which the handle is turned. Attached to
the spindle of the handle are two ratchet wheels having their teeth formed in
opposite directions; the said crank works frictionwise with one of the ratchet
wheels which allows of the window being lowered by the pressure of the hand
without using the handle. The other wheel is rigidly fixed to the handle spindle
and in the teeth of the said ratchet wheels works a compound spring ratchet the
main part of the ratchet gears into the wheel which works frictionwise with the
crank and the other part of the ratchet gears into the ratchet wheel fixed rigidly
on the spindle of the handle; these ratchets operate in such a manner that when

main ratchet to fall successively into the teeth of its ratchet wheel until the sash
frame is raised to its desired position when the handle will be prevented from
turning any further; by turning the handle to the left hand, the ratchet wheel
fixed rigidly on the handle spindle is first moved the distance of the length of a
tooth in the wheels and by this motion the main ratchet is raised out of its ratchet
wheel by the second part of the ratchet acting on a pin in the main ratchet thus
allowing the sash frame to be lowered tooth by tooth until the turning of the
handle stops and by this arrangement the window can be maintained at any
position or height.
Instead of the hereinbefore described compound ratchet arrangement a rigid
crank may be fixed on the handle spindle the crank having a circular portion with
notches or teeth cut therein and a spring locking piece taking into these teeth in
such a manner that it can be unlocked on turning the handle in either direction.

We HARRY EDMUND WINTER of 30 Palace Street, Buckingham Gate in the
county of Middlesex, Gentleman, JEAN LODOÏS MÉRIGOT of 56 Conduit Street,
Regent Street in the county of Middlesex, Medical Electrician and WALTER FROST
of 92 Copeland Road, Peckham Rye in the county of Surrey, Electrical Engineer do
hereby declare the nature of our said invention for " 'IMPROVEMENTS IN APPARATUS

n
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 improvements in apparatus for raising and lowering the
sliding windows of railway and other carriages the object of the invention being
the production of an apparatus whereby the sashes can be easily and quickly
opened and closed by merely operating by the hand or handles or knob on the
inside of the carriage door or window.
In carrying out our invention the sash frame carrying the glass is made to freely
run up and down in grooves or guides as usual and the said sash frame is counter
balanced by a spring or weight; along the bottom of the sash frame is a slot in
which runs a small wheel or runner block; the said wheel or runner block is
attached to the end of a radiating lever jointed at the other end to the side of the
sash box, and at a short distance from this joint there is jointed on the radiating
lever a link, which is connected at the other end to a crank on the spindle of the
knob or handle in such a manner that when the handle or knob having the crank
is turned it communicates a motion to the radiating lever by means of the link and
by means of the radiating lever a raising or lowering motion is given to the sash
frame according to the direction in which the handle is turned. Attached to the
spindle of the handle are two ratchet wheels having their teeth formed in opposite

page_text: directions; the said crank works friction wise with one of the ratchet wheels
which allows of the window being lowered by the pressure of the hand without
using the handle.
The other wheel is rigidly fixed to the handle spindle and in the teeth of the
said ratchet wheels works a compound spring ratchet; the main part of the ratchet
takes into the wheel which works frictionwise with the crank and the other part
of the ratchet takes into the ratchet wheel fixed rigidly on the spindle of the
handle; these ratchets operate in such a manner that when the handle is turned
to the right hand the ratchet wheels revolve and allow the main ratchet to fall
successively into the teeth of its ratchet wheel until the sash frame is raised to its
desired position when the handle will be prevented from turning any further; by
turning the handle to the left hand the ratchet wheel fixed rigidly on the handle
spindle is first moved the distance of the length of a tooth in the wheels the ratchet
wheel fixed on the handle spindle having a pin which works in a slot in the ratchet
wheel which is loose on the handle spindle which arrangement allows of the said
motion and by this motion the main ratchet is raised out of its ratchet wheel by
the second part of the ratchet acting on a pin in the main ratchet thus allowing
the sash frame to be lowered tooth by tooth until the turning of the handle stops
and by this arrangement the window can be maintained at any required position
or height.
Instead of the hereinbefore described compound ratchet arrangement a rigid
crank may be fixed on the bandle spindle the crank having a circular portion with
notches or teeth cut therein and a spring locking piece taking into these teeth in
such a manner that it can be unlocked on turning the handle in either direction or
the crank may operate without the said notches or teeth and spring locking piece.
In order to enable our invention to be fully understood we will proceed to
describe the same by reference to the accompanying drawings in which figure 1,
represents an elevation of the outer side of a railway or other carriage door shewing
our improved apparatus for raising and lowering the window of the same applied
thereto; and in which an arrangement of ratchet wheels is employed to admit of
the window being lowered by the pressure of the hand alone when required; in
this view part of the frame of the door is removed to more clearly illustrate our
invention and the window is shewn in its raised or closed position; figure 2, is a
vertical transverse section of the same on line A. B of figure 1; figure 3, is a similar
view to figure 1, but shewing the window in its lowered or open position; figures 4,
5 and 6, are detached views drawn to a larger scale shewing the arrangement of
the ratchet wheels; figures 7, 8 and 9 are similar views to figures 1, 2, and 3, but
shewing the improved apparatus arranged to operate without the ratchet arrango-
ment. Similar letters in all the figures represent similar parts.
We will first describe our invention by reference to figures 1 to 6.
a, is the sash frame of the window made to freely run up and down in the
grooves or guides b, in the frame of the door c (or of the window) in the usual
manner; d, is the spring for counterbalancing the weight of the sash frame (or a
weight may be employed for this purpose); e, is the slot at the bottom of the sash
frame a, and f, is the small wheel, roller, or runner block which runs in the slot e;
g, is the radiating lever to one end of which the roller f, is attached, the other end
being jointed at n, to the side of the sash box i; j, is the link jointed at k to the
radiating lever g, and 2, is the crank on the spindle m, of the knob or handle n, to
which crank, the other end of the link j, is jointed as shewn; o, and p, are the
two ratchet wheels having their teeth formed in opposite directions as shewn
clearly in elevation at figures 4 and 5 and in section at figure 6; the ratchet
wheel o, is loose upon the handle spindle m, and works frictionwise with the
crank, by means of a spring plate q, rivetted or otherwise suitably fixed to
the ratchet wheel o, and bearing upon the surface of the boss r, of the crank
as shewu in figure 6; the ratchet wheel o, is provided with a boss 8, upon
which the boss r, of the crank can rotate when the window is lowered by the
pressure of the hand without using the handle n; when however the window is

page_text: raised or lowered by means of the handle n, the boss of the crank is by means of
the said friction forced to rotate with the ratchet wheel o, as hereinafter described;
the other ratchet wheel p, is rigidly fixed to the handle spindle m; t, and u,
represent the compound spring ratchet; the main part t, thereof takes into the
ratchet wheel o, and the other part u, pivotted to the main part t, takes into the
ratchet wheel p; v, is the pin on the ratchet wheel p, and w, is the slot in the
ratchet wheel o, in which slot the pin v, works and by means of which the ratchet
wheel p, is allowed (when the handle n, is turned towards the left hand to lower
the window) to be moved the distance of the length of one tooth; x, is the pin on
the main ratchet t, against which the ratchet u, bears when its ratchet wheel p, is
being turned towards the left hand as already described and by which motion the
main ratchett, is moved out of the teeth of its ratchet wheel o, and the window by
continuing to turn the handle is lowered tooth by tooth into any desired position.
To raise the window the parts being in the position shewn in figure 3, the
handle m, is turned towards the right hand in the direction indicated by the arrow
in figure 4, when the main ratchet t, as the ratchet wheels o, and p, revolve will
fall successively into the teeth of its ratchet wheel o, and the part u, of the
compound ratchet will pivot on the main ratchet t, and will pass over the teeth of
its ratchet p; the ratchet wheels as they revolve will carry with them the crank l,
which by means of the link j, will cause the radiating lever g, to raise the window,
the roller f, meanwhile sliding in its slot e, until the window is closed when the
handle will be prevented from turning any further or until the window is raised
to any other required position or height at which position or height it will be
maintained.
To lower the window the handle n, is turned towards the left hand side in the
direction indicated by the arrow in figure 5 when the main ratchet will be moved
out of the teeth of its ratchet wheel o, in the manner herein before described and
shewn in the said figure 5 and both ratchet wheels will be free to rotate and will
carry with them the crank 1, until the window has been lowered to the required
position by means of the link j, and lever g, when the handle n, is released and the
window will be maintained in the said position.
If the window be pressed by the hand in order to lower the same the ratchet
wheels will be prevented from moving by means of the compound ratchet and the
boss r, of the crank will be forced by the window operating the link j, and lever g,
to move friction wise over the ratchet o.
In the arrangement shewn in figures 7, 8 and 9 in which the ratchet mechanism
is dispensed with I have shewn a coil spring contained within a barrel y, for
counterbalancing the weight of the window and a tape or band g, of metal or other
suitable material passes round the said barrel and is attached to the radiating
lever g, and a rigid crank is employed for operating the lever g, and raising and
lowering the window.
To raise the window the parts being in the position shewn in figure 9, the
handle n, is turned towards the right hand side whereby the crank 1, will raise the
link j, and radiating lever g, thereby raising the sash frame a, which will remain
in any position to which it may be raised or lowered by being counterweighted by
the coil spring which operates the barrel y, and winds the tape or bands, thereon
and assists in raising the radiating lever g.
To lower the window the handle n, is simply turned in the opposite direction
and the operation of the parts will be well understood without further description.
If required the crank 1, last herein before described may have notches or teeth
cut in its circular portion and a spring locking piece taking into these teeth in
such a manner that it can be unlocked on turning the handle in either direction.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
(1) In apparatus for raising and lowering the windows of railway and other
