PROVISIONAL SPECIFICATION.
Improved Means of Supporting Railway and other Carriage
Window Sashes.
I, EDWARD JACOB HILL, of 6, Westminster Chambers, Victoria Street, in the City
of Westminster, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
My Invention relates to an improvement in holders for retaining the windows of
railway and other carriages at any desired height; and it consists in an improvement
on the invention for which foriner Letters Patent were granted to me dated the
29th day of January 1886 No. 1332.
The sash retainer described in the specification of my former patent consists of a
gripping lever pivoted on the upper cross-member of the sash, the one end of the lever
acting as a gripping jaw which embraces and, in the normal position of the levor,
binds against a vertical rib fixed to the stile of the door. When the said lever is
mounted in a cavity formed in the cross member of the sash, the cutting away of the
wood of the sash stile, necessary to admit the rib and to allow the lever jaw to work,
is apt to weaken the tenon and mortise joint of the stile with the cross member of the
sash frame; and the object of my present improvement is to provide means whereby
to strengthen this joint and at same time reduce the time required for, and the cost of,
fitting the device to the sash and to ensure its more perfect working..
My improvement consists in providing a metal plate of such form that it is adapted
to retain the gripping lever and the spring in their proper working position and at
same time to embrace the edge of the tenon where the same is exposed by the cutting
away of the cross-member in which the corresponding mortise is formed, and so
constitute at once a mounting for the lever and a strengthening piece for the wood
work in which it is mounted. Accordingly, this plate which is screwed in the cavity
in which the lever works, made with a return end or flange at right angles to its
plane, which embraces the edge of the tenon and affords the support of which the
tenon is deprived by the cutting away of the wood, as above mentioned, and the plato
near its inner end is formed with a piece projecting from its top or bottom edge,
which piece is folded over parallel with the main body of the plate and sufficiently
distant therefrom to admit the lever between them. Between these two parallel
members of the plate, the lever and its spring are placed and the plate is fixed in
position by screws passing through both menibers of the plate, one screw serving also
as the fulcrum of the lever whilst the other passes through the bow of the spring and
so retains it in position whilst the tail of the spring abuts against the folded part of
the plate. The screws are so inserted, or bear in such manner against the plate, that
they tend to draw the return outer end of the plate tightly against the tenon which it
is intended to support.
The cavity in which the lever is mounted is made in the inner face of the cross-
member of the sash and is boxed in by a thin cover plate of wood which completos
the said cross member and conceals the parts from view with the exception of the
thumb piece for operating the lever which projects through a slot in the cover plate
and is acted on in conjunction with the sash lifter, as described in my former
pecification.

I, EDWARD JACOB HILL, 'of 6, 'Westminster Chambers, Victoria Street, in the City
of Westminster, Civil Engineer, 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 an improvement in holders for retaining the windows of
railway and other carriages at any desired height; and it consists in an improvement
on the invention for which former Letters Patent were granted to me dated the 29th
day of January 1886, No. 1332.
The sash retainer, which is similar to and acts in the same way as that described in
the specification of my former patent, consists of a gripping lever pivoted on the
upper cross-member of the sash, the one end of the lever acting as a gripping jaw
which embraces, and in the normal position of the lever binds against, a vertical rib
fixed to the stile of the door.
The said lever is usually mounted in a cavity formed in the cross-member of the
sash and the cutting away of the sash stile necessary to admit the rib and to allow
the lever jaw to work, is apt to weaken the tenon and mortise joint of the stilo with the
cross-member of the sash frame; and the object of my present improvement is to
provide means whereby to strengthen this joint and at same time reduce the time
required for, and the cost of, fitting the device to the sash and to ensure its more
perfect working.
Reference is to be had to the accompanying drawings forming part of this specifica-
tion wherein figure 1 shews a face view of the lever as mounted in the upper part of
the sash, the cover plate being removed and the lever being represented in engage-
iment with the rib fixed to the stile of the door. Figure 2 is a horizontal section, and
figure 3 an end view, of same. Figure 4 shews the mounting for the lever, as
developed in the flat. The same letters of reference indicate the same parts in all the
figures.
My improvement consists in providing a metal mounting for the gripping lever, of
such form that it is adapted to retain the gripping lever a and the spring in proper
working position and also to embrace the part of the tenon where exposed by the
cutting away of the end of the cross-member in which the tenon is mortised and so
strengthen the joint of the sash frame. This mounting which is received in the
cavity in the top cross-member d of the sash is made of a metal plate e, of the form
shown developed in the flat in figure 4, the part e' which projects from its upper edge
being folded over along the line e so as to lie parallel to the main body e of the plate
and sufficiently distant therefrom to admit the lever a between the two parts e and e¹.
The plate may also be formed with a strap piece y near its outer end which, like the
part e, is doubled over parallel with the plate e at gl and serves to assist in retaining
the lever in position but this is not essential. At the outer end the plate is formed
with a return end or flange f bent up at right angles on line f¹ to the plane of the
plate, which flange covers the end of the tenon. The lever a and its spring bare
placed between the parts e and e¹, as shewn, and the mounting is fixed in position by
screws passing through both members e and e¹ of the plate, one screw h serving also
as the fulcrum of the lever a whilst the other screw i passes through the how of the
spring and so retains it in position whilst the tail of the spring abuts against the bend
uniting the parts e and e¹ of the plate. The flange is held tight up to the wood-work
by screws inserted through it.
The cavity in which the lever is mounted is made in the outer face of the cross-
member of the sash and is boxed in by a thin cover plate of wood which completes
the said cross-member and conceals the parts from view. The thumb-piece k
for operating the lever a projects through a slot in the cross-member and is acted
on in conjunction with the sash-lifter 1, as described in my former Specification.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, declare that what I
claim is
The combination with the gripping lever of the herein described mounting, con-
sisting essentially of a metal plate adapted to retain the lever and its spring in position
and to brace the tenon joint of the frame, substantially as specified.
