Windows of Railway and other Carriages

I, DOUGLAS ALLPORT of 9 Fenchurch Buildings London, Merchant do hereby
declare the nature of my invention for IMPROVED MEANS OF MOVING & FASTENING
IN POSITION THE WINDOWS OF RAILWAY & OTHER CARRIAGES to be as follows:-
(1 & 2 are alternative ways.)
i. At the centre of the top bar of the window, I place a handle capable of being
turned only from the horizontal to the vertical position & back again. On the
spindle of this handle are two projections opposite one another, & operating two
rods which extend along the wooden frame to the sides of the window. The ends
of these rods may operate cams or may be covered with india rubber or otherwise
prepared to give them the necessary hold upon the sides of the window frame,
towards which they are forced by the turning of the handle, thus locking the
window in whatever position it may be when the handle is turned.
2. I propose to raise the window by a handle connected with the lower bar &
projecting thro' a vertical slit in the lower part of the door, into the carriage. This
handle moving up & down in the slit, raises or lowers the window & locks it
in position, upon being turned, by means of a cam (or other arrangement for a
similar purpose).

I DOUGLAS ALLPORT of N° 7 St Benet Place London E.C. Merchant do hereby
declare the nature of my invention for IMPROVED MEANS OF MOVING & FASTENING
IN POSITION THE WINDOWS OF RAILWAY & OTHER CARRIAGES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
-
At or near the centre of the top bar of the sash (or the lower bar in case
the window is one which opens upwards) I place a handle capable of being turned
from the horizontal to the vertical position & back again Fig. 1 A. This handle is
similar to those used at present on several railways inasmuch as it forms the means
of raising & lowering the window, but it differs from any hitherto used inasmuch
as it is capable of locking the window in any position by being turned, & of
releasing it by a similar operation. The way in which I prefer to effect this end is
as follows
-
Keyed or otherwise fastened on the spindle of this handle, are either one or two
lugs B; in the latter case on opposite sides of the spindle. I will describe one only,
as the second is not generally necessary, but if used is similar. This lug being at
right angles to the handle projects from the spindle horizontally when the handle
is vertical & vice versa. A slit in the lug C, Fig. 2, receives the end of a rod
or arm D which is connected with it by a pin E passing thro' holes in the lug &
arm and secured by a screw cut on one end of the pin, & fitting into a female screw
in the lug. This arm passes along the sash bar S, either outside it or preferably let
into a groove in the wood. The end of the arm is extended so as to form a plate F,
strengthened at the back in the way shown in Fig. 2 & having a small projection
at right angles to its face at each end. In the centre of this plate on the outer
face, I drill a hole & tap it for a screw. On the face of this plate fitted between
the projecting ends I place a pad consisting on the under side of a layer of india.
rubber G, attached to a piece of sole leather, wood or vulcanized fibre H of similar
A pin, screwed at the end I passes thro' this pad into the hole in the plate,
securing all together; & the head of this pin being deeply countersunk in the wood
or leather allows the pad to be compressed. A steel or other metal spring or case
may be used instead of or in conjunction with the India rubber so as to take
the wear against the groove, & may also be used to retain the India rubber in
position.
size.
Fig. 2 shows a section thro' the sash bar S, J representing a circular bearing-
plate screwed onto the inside of the sash bar by three screws, one of which is
countersunk & the other two have projecting heads, which form stops for the
handle at the horizontal & vertical positions. K is a circular bearing plate secured
by screws; L is a thin wood or metal cover enclosing the whole of the mechanism
except the end of the spindle which passes thro' a hole in M, a bearing plate
screwed on the outside of the cover L. The cover is cut away underneath to give
room for the lug piece which projects into it about of an inch.

page_text: The fastener as described I fix in the sash bar preferably as shown in Fig. 2, &
the arm or rod lies in a groove cut in the outer face of the bar from the centre to
the side. This groove at its lower edge tends downwards so as to pass as near the
corner of the glass as convenient, & it is of sufficient width to allow the rod
to move freely when the lug is turned by the handle, & also to allow of its
assuming a horizontal position. It is of sufficient depth to allow the rod head &
pad to move clear of the cover. The pad lies quite within the bar when the handle
is horizontal, but is thrust outwards when the handle is turned, so as to push
against the groove of the window frame & thus jam the sash against the opposite
side of the frame. When loose the weight of the arm keeps it at the bottom of
the groove, inclining downwards from the centre. When the window is jammed
by the projecting end, any slip of the sash tends to raise the position of the rod
towards the horizontal, thus increasing and forming an automatic adjustment of
the pressure originated by the movement of the handle. The rod or arm may also
be so arranged as to act as a bolt, or to engage with a notched rack in the window
frame, or to operate a cam, but the before-described arrangement is the one
I prefer.
1
In some cases it may be preferable to raise the window from below, & I therefore
propose, in such cases to connect the lower bar of the sash with a handle projecting
thro' a vertical slit in the lower part of the door into the carriage. This handle
may either be attached directly to, or connected with the sash bar, or to or with a
sliding block or other support upon which the sash may rest. The handle by
being turned, as in the former arrangement, locks or releases the block or the
sash as the case may be. In this arrangement the arm or rod may be shortened or
replaced by a cam or screw to jam the window.
Having now particularly described & ascertained the nature of my said
invention, & in what manner the same is to be performed, I declare that what
I claim is:
1. The employment of a moveable handle on the sash bar, which shall suffice for
the fastening as well as the raising & lowering of the sash substantially in the
manner described.
2. The connecting of this handle with the frame of the window by means of a
rod or arm worked by the movement of the handle and adjusted by the downward
pressure of the window substantially in the manner described.
3. The employment of a moveable handle projecting thro' the lower part of
the door for the purpose of operating the window substantially in the manner
described.
