PROVISIONAL SPECIFICATION.
Improvements in Railway-carriage Window and other Sash Holders.
1, GEORGE INGRAM, of 44 Chapel Street, Marylebone in the County of Middlesex
Clerk, do hereby declare the nature of this invention to be as follows:-
I place a metallic spring, resembling in appearance the archer's bow, on the top of
the carriage sash frame, and conveniently on other windows. At each end of the said
spring I fix two metal brackets or stays, into which brackets or stays I fit two sliders
moving on the sash-frame horizontally, the ends of the said spring pressing against
the sliders. Over the centre of the bow of the said spring I fix a metal guard and
stop, the said spring moving freely behind the said guard, and stopping when lifted
bigh enough by the finger of the operator. The said spring guard and stop also serves
as a thumb-rest whilst the finger is pressing the spring to lower the window. On each
side of the door frame I fix a vertical wood guide or slide, preferably I use beechwood,
or I fit the said sliders into grooves made in the door frame. I fit the said sliders on
to the said guides or slides for the sliders to run up and down upon-grooves serving
the same purpose where practicable. When pressure is put under the centre of the
said spring, its ends, previously pressing against the said sliders and slides, and
holding the window up, cease to press, and the window is thus raised or lowered to any
desired position.
COMPLETE SPECIFICATION.
Improvements in Railway-carriage Window and other Sash Holders.
I, GEORGE INGRAM, 4ª Chapel Street Marylebone, Middlesex 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 a sash holder for railway carriage and other windows, that
is to say an appliance which permits the sash to be freely raised or lowered by hand,
but holds the sash at any desired part of its course, as I will describe referring to
the accompanying drawings.
Fig. 1 is an internal elevation of a railway carriage window shewing a sash holder
according to my invention applied to it. Fig. 2 is a part elevation to an enlarged
scale, Fig. 3 is a vertical section on X and Fig. 4 a vertical section on Y of
Fig. 2.
Upon the upper bar A of the sash frame near each end of it I fix a staple B which
receives the limb of a T piece or slider C fitted to slide within the staple B. Against
the hollowed end of this limb bears the rounded end of a slightly bent blade spring D
which extends across the sash, its other end bearing in like manner against the limb
of an opposite T piece or slider, and both sliders bearing against the inner faces of the
window frame. To the middle of the spring D is fixed a loop E which is partly
engaged within a guard bracket F fixed to the sash. The upper face of this bracket
is somewhat hollowed to receive the thumb, and the lower part of the loop E projects
down below the guard so that, when the fingers are applied to the loop E while the
thumb bears on the upper face of F, the pressure of the fingers will raise the middle
part of the spring D bending it farther and consequently relieving the pressure of its
ends against the sliders C. In this condition the sash can be freely moved upwards or
downwards along with the sliders C; but, when the loop E is relieved from the pressure
of the fingers, the spring D tends to straighten, and its ends press the sliders C against
the sash frame, causing such frictional hold that the sash is retained in the position to

page_text: which it had been moved. The sides of the sash frame against which the sliders Crub
may be lined with strips of wood which can be removed when worn to have fresh strips
substituted for them. Although I have shewn the sash holder applied to the upper
part of the sash, which is the most convenient arrangement for a carriage window,
it might obviously be applied at the lower part or at any other part of the sash of
another window.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :
A window sash holder consisting of a bent blade spring extending across the sash and
pressing sliders against the opposite faces of the window frame, in combination with a
guard and loop at the middle of the spring adapted to receive the pressure of the thumb
and fingers for farther bending the spring and so relieving the pressure on the sliders,
substantially as described.
