Railway Carriages or other Travelling Vehicles.
I, JAMES HENRY WELLINGTON, of 3, Poets' Corner, Westminster, in the County of
Middlesex, Gentleman 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 improvements in, or relating to windows, specially
applicable to railway carriages or other travelling vehicles, whereby they are auto-
matically raised, on releasing a device, tending to lock or hold the same in any
desired position.
I place in the well of the frame as applied to a railway carriage, or like vehicle, a
pivoted lever connected to a spring or weight tending normally to pull on the lever.
The lever is jointed to another link or lever pivoted to the window frame, a toggle
arrangement being thus formed. The tendency of the spring is to force up the
window, and where such abuts on the frame in which the window slides, suitable
cushioning springs may be provided for the purpose of deadening the shock. To
retain the window in position, I may use an eccentric, or eccentrics, which may be
covered with rubber, or other soft material to drop on the window frame automatically
as the window rises, and may be released by a handle or catch to allow it to drop.
An eccentric or catch may be manipulated by hand to hold the window frame in
position as lifted by the spring. In order that the said invention may be more
particularly described and ascertained, reference is hereby made to the accompaning
drawings, in which similar letters of reference indicate corresponding parts.
The accompaning drawing represents the well of the carriage door with the
window up or closed, and the panelling removed to show the interior mechanism.
I place in the well B D C E of the frame U¹ DC V₁ the lever A, pivotted at the
bottom to a fixed iron bar F G, and at the top to another lever H by a similar pivot.
The other extremity of the lever H is pivotted to the window frame at K. To the
lever A. I attach another lever L, which at its lower end is pivotted to the fixed metal
bar G. I cut in the lover A the slot M M of any required dimensions, in which the
upper end of the lever L slides to and fro, by the opening and closing of the window.
[P11

page_text: To the lever L is attached a spiral spring N by means of a hook or other suitable
attachment: The upper part of the. spring N may be attached to a fixed metal
bar OP either by means of hooks or by cross pieces of metal Q, R, and S, to which
the upper part of the spring is nutted.
The tendency of the spring N is to force up the window when released by
application of the handle or push T placed in any required position for releasing the
spring. In the inner frame U BEV at the upper part UV I place cushioning
springs of india-rubber to deaden any shock arising from the upward movement of
the window. I place a small metal wheel X in the side of the window frame U¹D
CV to facilitate the rising and falling of the window. To retain the window in
position I use an eccentric W covered with rubber or soft material arranged so as to
drop on the window frame automatically as the window rises. I affix a small copper
leaf Y to allow of the window being opened to any required distance by ordinary hand
pressure.
This invention can be applied to windows of houses or vehicles of overy
description.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare what I
claim is
The opening and closing of the windows of railway carriages or other vehicles
automatically, substantially as herein before described and as the accompaning
drawings..
Dated this 7th day of December 1888. -
JAMES HENRY WELLINGTON.
