TRUVIDIONAL DIBUITIVATION.
Improved Means of Supporting Railway and other Carriage Window
Sashes.
I, EDWARD JACOB HILL, of 11 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 improvements in the means of supporting railway and
other carriage windows at any desired beight, of the kind described in a previous
application for Letters Patent dated November 3rd 1888, No. 15,922.
The sash retainer consists of a gripping lever mounted in the top cross rail of
the sash, the outer end of the lever having a jaw which, at the proper time, grips
a vertical rib fixed in the sash groove in the door.
The present improvements have for their object to avoid torsional strain on the
lever in the act of releasing it, to give easy access to the spring so as to admit
of its being replaced, when necessary, without dismounting the lever or its fittings,
and to enable the lever to be readily withdrawn and replaced, when worn, without
disturbing any of the other fittings.
My invention has for its object secondly to provide an improved construction of
the plate fitting in which the lever is mounted; and thirdly to provide an improved
means of fixing the rib in the grooves of the door stile in which the sash works.
According to my improvements, instead of operating the lever by a thumb-
piece attached directly to the inner end of the lever it is operated by a short
lever mounted immediately behind the sash lift and having at its free end a thumb
piece projecting from its front face and a stud projecting from the other face,
said stud engaging in a longitudinal slot in the inner end of the gripping lever
so as to transmit motion from the one lever to the other without causing any
tendency to twist the gripping lever whilst allowing the gripping lever to be freely
disconnected and withdrawn endwise when the top of the sash is raised above the
top of the door so that another lever may be readily inserted without disturbing
the other fittings.
The spring by which the gripping lever is held in its normal position is applied
to the thumb piece lever above described instead of to the gripping lever itself,
the spring and thumb lever being mounted in a cavity directly behind the sash
lift.
The mounting for the gripping lever is made of a single metal plate adapted to
be bent or folded to the form of a flattened tube or casing and within which the
gripping lever works; it is provided with extensions or tangs adapted to be bent
at right angles to said casing and to be cranked or bent so as to embrace and
strengthen the woodwork of the sash particularly in the region of the tenon
joint.
The rib, which is gripped by the lever for the purpose of supporting the sash,
is of L-shaped section and is fixed within the sash groove in the stile of the door.
As the latter is usually worked in the solid it is difficult to fix the rib in the
groove by ordinary means, and to provide a ready means of fixing it I form
L-shaped or bayonet slots in the edge of the rib by which it is to be fixed and
countersink a groove in the bottom of the sash groove in which is to be received
the notched edge of the L-shaped rib and to the bottom of the sash groove 1 fix
studs which correspond in position to the bayonet slots in the edge of the rib and
lie across the groove in which the notched edge is to be received so that, the said
groove having been made and the studs fixed, the L-shaped rib may be quickly

page_text: and securely fixed merely by being pushed inwards and longitudinally so as to
engage the bayonet notches on the studs.

COMPLETE SPECIFICATION.
Improved Means of Supporting Railway and other Carriage Window
Sashes.
[, EDWARD JACOB HILL of 11, 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 improvements in the sash retainer whereby railway and
other carriage window sashes may be supported at any desired height, for which
Letters Patent were granted to me dated November 3rd 1888, No. 15,922.
The said sash retainer consists of a gripping lever mounted in the top cross rail
of the sash and having a jaw which embraces, and automatically grips a vertical
rib fixed in the groove in the door stile in which the sash runs.
The present improvements have for their object to avoid torsional strain on the
said lever in the act of releasing it, to give easy access to the spring by which
the lever is thrown into action, so as to admit of its being replaced, when necessary,
without dismounting the lever or its fittings; and to enable the lever to be readily
withdrawn and replaced, when worn, without disturbing any of the other fittings.
The improvements have further for object to provide a better means of fixing the
rib in the grooves of the door stile in which the sash works.
Reference is to be had to the accompanying drawings, forming part of this Specifica-
tion, in which
Figure 1 shews, in external elevation, part of the window sash and door-stile, the
covering plate being removed from the former and the latter being partly in section to
shew the working parts.
Figure 2 is a horizontal section, on line 1-1 Figure 1; and
Figure 3 shews, in perspective view and apart from the door, a part of the rib which
is gripped by the lever.
Similar letters of reference indicate like parts in all the figures.
A is the sash frame, B the door stile; the gripping lever, D the jaw at the outer
end of said lever, E the rib gripped by said jaw and fixed in the groove of the door
stile B in which the sash works. The lever C is mounted to work in a cavity made
preferably in the outer face of the top cross-rail of the sash frame and covered by a
plate, all as described in the Specification of my said former Patent, and the gripping
operation whereby the sash is supported is similar to that before described.
According to my improvements, instead of the thumb-piece F for operating the
lever C being attached directly to the inner end of the lever and passing through the
sash, as in my former Patent, it is affixed to a short lever G mounted immediately
behind the sash lift H, to which it is pivoted at g, and having at its free end a stud g¹
projecting through a slot a in the sash rail and engaging by a longitudinal sliding
connection with the inner end of the gripping lever so that, in raising the latter by the
lever G, there will be no tendency to twist the gripping lever C. This connection is
preferably formed by the end of the lever C passing through a cross-slot in the stud g²,
as shewn, so as to permit of the gripping lever being disconnected and withdrawn
endwise when the top of the sash is raised above the top of the door for the purpose of
inserting another lever without disturbing the other fittings.
The spring I by which the gripping lever C is held in its normal position is applied

page_text: to act on the thumb piece lever G instead of on the gripping lever itself, the spring I
and thumb lever G being lodged in a cavity formed in the base plate of the sash lift H,
as shewn. The fulcrum of the lever C is at k upon the lower edge of a built-up
mounting formed of the said fulcrum plate and a covering plate K which also serves
to strengthen the tenon joint of the sash frame:
The rib E which is gripped by the lever C for the purpose of supporting the sash, is
of metal of L-section and is fixed within the sash groove in the stile B of the door.
As the latter is usually worked in the solid, it is difficult to fix the rib L in its proper
position in the groove by ordinary means, and to provide a ready means of
fixing it I form L shaped or bayonet slots in the flange of the rib by
which it is to be fixed, and plough a groove b in the bottom of the sash
groove at one side thereof, in which groove is to be received the slotted edge
of the said flange; and to the bottom of the sash groove I fix plates M which
correspond in width and position to the bayonet slots in the rib and whose
ends lie across the groove b so that the plates M having first been thus fixed, the rib L
may be quickly and securely fixed, (in the position shewn by the slotted flange) merely
being pushed into the groove b and the rib then moved longitudinally so as to engage
the bayonet slots / on the plates M.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is;
1. In the herein-described sash retainer, the combination, with the gripping lever C,
of the thumb lever G to which the lever C is detachably connected, as and for the
purpose specified.
2. In the herein-described sash retainer, the thumb lever and spring arranged to
work behind the base plate of the sash lift at the inner face of the sash, the lever being
provided with a stud playing in a slot in the sash, in combination with the gripping
lever mounted at the outer face of the sash with a sliding connection between the
gripping lever and stud, substantially as specified.
3. The herein-described mode of fixing the L-section sash-supporting rib in the
sash groove of the door-stile by a bayonet slot connection, substantially as specified.
Dated this 29th day of September 1890.
