PROVISIONAL SPECIFICATION.
Simplifying and Facilitating the Opening and Closing of the
Windows of Railway and Road Carriages and similar Windows.
I, JOHN KIDSON JACKSON, 27 Caledonia Road, Batley, Yorkshire, Methodist
New Connexion Minister, do hereby declare the nature of this invention to be as
follows:
The end, as above stated, is secured by directing the path and progress of the
window (as it is being raised or lowered by strap in the usual way) in a det
adefined
course, 1st to its "rest" (closed) and 2nd back into its socket or case.
To do this, hard metal studs or pins are attached to the right and left top corners
of the sash (Figs. 1 & 2). These studs, as the window is being opened or closed,
come in contact with and pass certain spring catches which prevent their return
and direct their progress, and that of the sash, as desired.
The catches are contained and arranged in a metal box (Figs. 3 & 4).
The box is sunk (inserted) in the inner side of the frame of the window, very
near to the top of it. The box shewn in Fig. 3 is for the right hand side of the
window frame. A similar box, with the catches arranged the reverse way, is to be
inserted in the left hand side of the window frame..
'
When the window is to be closed, and is raised by the strap, the stud travels up
the groove A (cut in the window frame) and enters the box at B. Continuing its
progress to point C it pushes aside, to the left, the upper portion of the top catch.
When the stud has reached point C the upper portion of the top catch will have
sprung back to its original position. From point C the window descends by its
own weight, guided by the contour of the catch,. to point D, and, in its progress,
pushes aside to the right the lower portion of the upper catch, which, being
passed, returns to its place, and prevents the return of the stud. At point D the
stud rests in the hollow of the fixed block G. The window, thus. closed,.is
suspended, on two studs, resting on two fixed blocks, one on each side, and, to
prevent draught and rattle, springs are made to press the bottom (horizontal part)
of the sash against the inner surface of the outer side of the window case (both
surfaces being clothed with brass plates, as now) and the strength of such
springs to be so proportioned as not to prevent the sash from descending, easily, by
its own weight. To open the window the sash is raised (by strap) casising the stud
to travel to point E, and, in its progress, pushing aside the upper portion of the
lower catch, which, having been passed, returns to its position. From point E the
window descends by its own weight. guided (the stud that is) by the obliquity of
the lower catch, and, in its progress, pushing, aside the right hand arm of the
lower portion of the upper catch (thus elongated simply to prevent the stud from
being diverted, when being raised, from its true path, & travelling from B to E instead
of from B to C) down, back to B and (the stud re-entering the groove A) so far
toward the bottom of the case or socket as may be desired.
Also a channel or groove is to be sunk in the floor of the box, almost exactly
coincident with the path of the stud, in which channel the end of the stud ahail
travel. The outline of the channel to be so arranged as to bear, so far as is
possible, the pressure of the stud, and thus relieve any strain of the studs on the
Catches.

The invention for which Provisional protection is asked consists in (1) the studs,
attached to the sash, (2) the catches, to direct the path of the studs, (3) the channel,

page_text: to reduce the strain on the catches, (4) the application of this contrivance either to
the top or bottom of carriage window frames, and (5) such modification of the size
and shape of the parts as may be necessary in applying the contrivance to the
largest and smallest of carriage windows as also to existing windows.
H. H. in Fig. 3 simply indicate the screw holes for attaching the box to the 5
window frames.

The outline of the channel is shewn with approximate correctness by the dotted
lines in Fig. 3.

I, JOHN KIDSON JACKSON, 27 Calédonia Road, Batley, Yorkshire, Methodist
New Connexion Minister, 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:-
OBJECTS AND AIMS.
The ends aimed at by this invention are simplicity (the impossibility of "getting
wrong") in the opening and closing of the windows of carriages, along with the
avoidance, in the act of closing a window, of the "lifting over of the bottom of
the sash, and of an open ("yawning") window case when the same is closed, and
of the departure of the sash from a perpendicular position, and of all stiffnes
("dragging") in its upward or downward course, as also a complete exclusion of
draught and prevention of noise.
In the accompanying drawings :--
Fig. 1 is the box, full size, with catches fixed.
Fig. 2 is the same, with the catches &c. removed, shewing the course of the
channel.
Fig. 3 is a section of the box at J shewing the thickness of the raised parts, and
of the catches.
Fig. 4 is the end of the box shewing the opening B, and the thickness of the
floor,
"

Fig. 6 is the same,-side view.
CONSTRUCTION AND FIXING.
To carry out this invention hard metal studs, on jointed arms, are attached to
the right and left top corners of the sash, as shewn in Figs. 5 and 6. The arns
may extend above the top of the sash more or less to apply to varying patterns of
windows. The metal box, with catches as shewn in Fig. 1 is sunk or inserted in,
and screwed to, (the holes for such screws indicated by G G Fig. 1) the inner
side of the window frame at a convenient distance from, but near to, the top.
Fixedness and constancy of bias is given to both catches by the spring F, or
by some other ordinary spring.
The box and stud shewn in the drawings are for the right hand corners of the
window frame and sash, viewed from within the carriage; a similar box and
stud but arranged and fitted the reverse way are applied to the left hand top
corners of the sash and frame.

page_text: If water enters between the weather plates (which it is believed will not be the
case if the said plates be accurately fitted) the lower edge of the outer plate
shall be slightly bent outwardly and made to overhang a narrow (say inch)
brass gutter fitted in the inside of the outer side of the window case, and the
water thus carried away. The upward course of the sash to be effectually stopped,
by ordinary means, say inch before the stud reaches points C and E, to prevent
the stud from being brought into violent contact, at those points, with the upper
catch.
OPERATION.
When the window is to be closed the sash is raised by strap in the usual way.
The stud H is thus made to travel up the groove A, and enters the box at B;
continuing its course to point C it pushes to the right both the left hand limb of
the lower catch and the upper catch. Having reached point C both catches will
have returned to their original positions. The window is then "let go," and
descends by its own weight, and in so doing the stud pushes aside the upper catch
to the right. When the stud has reached point D the upper catch has returned
to its position, and at point D the window is closed, the sash being suspended on
the 2 studs, right and left. To open the window the sash is again raised by
strap, the stud travelling from point D to point E guided by the contour of the
right hand side of the upper catch and by the channel, and pushing to the right
both upper limbs of the lower catch, as also the upper catch. When point E bas
been reached the catches have returned to their position; the sash is again "let
go" and descends by its own weight, the stud travelling from E to B, and in its
course pushes to the left the lower extremity of the lower catch, and so back
into the groove A, and so far further down as may be desired.
(If it be necessary which it is believed will not be the case with a well maile
window, so suspended, and sliding in a channel which does not taper-slight
springs may be applied to press the bottom of the sash outwardly when the window
is closed.)
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:
(1.) The studs on jointed arms attached to the top corners of the sash and the
suspension of the sash thereby when the window is closed.
(2.) The spring catches arranged and fixed in the metal box as shewn in the
drawings, Fig. 1.
(3.) The employment or non-employment of the channel.
(4.) Such modification of the shape, size, strength, and combination of the
several parts of the invention as may be necessary in applying the same to the
varying sizes and patterns of windows.
