TRUVIDIONAL SPECIFICATION.
Improved Means of Supporting Railway Carriage and other similar
Sash Windows.
We, EDWARD JACOB HILL, of 11, Victoria Street, in the City of Westminster,
Engineer, and VINCENT WALKER HILL, of the Hull Barnsley and West Ruling
Junction Railway and Dock Company's Offices, Tull, in the County of York,
Secretary and General Manager do hereby declare the nature of this invention to
be as follows
-
This invention relates to improvements in the means of supporting, at any
required height, the window sashes of railway and other carriages, ships' deck
cabins, and the like, for which former Letters Patent were granted to us dated
the 7th day of December 1893, No. 23,602.
The present invention has for its object to improve and render more efficient
the action of the window supporter and to adapt it to the exigencies of particular
circumstances
The device, as described in the Specification of the former Patent aforesaid, com-
prised various forms or arrangements and modes of applying a gripping jaw carried by
a lever pivoted to the cat ringe door or window frame and adapted to become jammed
against the sash or its glass, (or ce versa,) with a pressure due to the weight of the
sash so as to firmly retam the latter at whatever height it may be raised and yet
admit of being automatically disengaged from its grip by the slightest lifting motion
of the sash, the action of the jaw being to bind the sash in its grooves in such
manner that rattling is prevented
The first improvement has for its object to enable the rubber pad which forms
the gupping surface of the jaw to be more readily fitted and renewed, and the
combination of elasticity and resistance requisite to ensure a proper grip to be
readily obtained, without using any special make of rubber. For this purpose we
use ordinary rubber tubing and secure it in the nearly cylindrical metal socket by
driving a taper wooden or other pin tightly into the bore of the rubber whereby the
acting part of the rubber is made to sufficicutly project from the metal and receives
the requisite amount of support to obtain the deaned grip.
Another improvement relates to the form of the device which is adapted for use
in conjunction with the sash lifting strap. In the formet arrangement the jaw
pressed against the glass of the sash only through the intervention of the strap and
a spring was so applied as to tend to throw the jaw out of operative position, the
Jan being thrown into position to act by the fiction of the stinp when the latter
was held in a particular position. According to the present arrangement the
gripping jaw is duplicated and adapted to bear duectly against the glass at ench
side of the strap by the friction of which it is thrown into operative position. For
this purpose the two jaws, each provided with a rubber pad, as before described,
are mounted on aims projecting fiom either end of a cylindrical boss mounted on a
pivot in the position on the garmish al usually occupied by the roller over which
the stiap passes and whose function this boss fulfils in so far as its limited capacity
for rotation will allow In addition to the aims carrying the jaws, thumb leveis
project from the ends of this boss by pressing on either of which the double jaw
will be thrown back from the glass to allow the sash to instantly fall, whilst the
Jaws are self-disengaging if the sash be lifted by means of the strap, and if not
D

page_text: already in contact with the glass will be caused to assume that position by the
friction of the stiap on the roller-like boss portion directly the strap is allowed to
run back in contact therewith.
The next improvement has for its object to enable the rubber gripping jaw to be
dispensed with, especially when the device is to be u-ed in extreme chmates. This
consists in making the gupping face of the jaw of metal and of such form that it
has a broad pressure surface to tbrust against the woodwork. To ensure the device
taking and maintaining the necessary hold, the jaw is also provided with a serrated
Burface which stands out beyond the thrust surface and embeds itself in the wood
sufficiently to produce the necessary friction to oscillate the gupping jaw and bring
it into position to act and this it will do, notwithstanding that it inay went a soit of
rough tack on groove in the wood work as it is not requied to support the weight of
the sash It will, therefore, always maintain a sufficient hold to fulfil its function
which is merely to ensure the necessary thinst of the plain part of the jaw by which
the weight of the sash is supported To prevent the making of the woodwork
being visible, the gupping jaw is so formed and located that it will thrust against
the bottom of run of the groove in which the sash slides and as close as possible to
the inner side of the groove where it will not be seen from inside of the carriage.
The same construction of Jaw may be used when mounted on the garnish rail or
window figme and bearing against the inner face of the sash frame close to the
side thereof which runs in the sash groove.
The gupping lever may be variously formed and mounted on the sash, or the
garnish rail, as the case may be. According to one form it is pivoted to the back
of a plate which is adapted to be fixed to the inner face of the sash over a recess cut
therein in which the lever works, the plate itself being slotted to give passage to
the tail end of the level which is provided with a thumb knob for actuating it by,
and forming a counter weight to throw the gripping surface into operative position.
The Luob is flush with the face of the plate which is countersunk or recessed to
afford space for the knob and for the thumb or finger of the person operating it
Or the gripping lever may be cranked to allow the jaw to enter the sash groove
whilst the lever is pivoted in a bracket fixed on and projecting from the inner face
of the sash.
Another modification consists in dispensing with the seriated part of the jaw and
making it a plain metal surface, but in this case it is necessary, in order to prevent
slipping, to form recesses at intervals in the botton or run of the sash groove for
the jaw to engage in and similarly when the jaw is mounted on the gainish rail oi
other pait of the frame and bears against the inner face of the sash Or in this
case, instead of recesses, projections may be fixed upon the sash for the jaw to
engage with.
In all cases where the device is mounted on the garnish rail the bracket on which
it is pivoted is adapted to straddle the upper rounded edge of the rail in such
a way as to be self-supporting without straining the screws by which it is fixed.

Improved Means of Supporting Railway Carriage and other similar
Sash Windows
We, EDWARD JACOB HILL, of 11, Victoria Street, in the City of Westminster,
Engineer, and VINCENT WALKER HILL, of the Hull, Barnsley, and West 5
Riding Junction Railway and Dock Company Offices, full, in the County of
York, Secretary and General Manager, do hereby declare the nature of this

page_text: invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement
-
This invention relates to improvements in the means of supporting, at any
required height, the window-sashes of railway and other carriages, ships' deck
cabins, and the like, for which former Letters Patent were granted to us, dated
the 7th day of December 1893 No 23,602.
The present invention has for its object to render more efficient and otherwise
improve the action of the window supporter and to adapt it to the exigencies of
particular circumstances
The device, as described in the Specification of the former Patent aforesaid,
consisted essentially of a gupping dog or jaw mounted on the door or window
frame and binding against the sash (or vice versa) so as to firmly retain the sash at
whatever height it may be raised and yet admit of beng automatically disengaged
from its grip by the slightest lifting motion of the sash, the action of the jaw being
to bind the sash in its grooves in such manner that rattling is prevented.
The improvements will be described seriatum, with reference to the figures of
the accompanying drawings, formning part of this Specification.
The first improvement, which is illustrated in Figure 1, has for its object to
enable the rubber pad which forms the gripping surface of the jaw to be more
readily fitted and renewed, to cause the rubber to project sufficiently from its
Bocket without being made of special form, aud to enable the exact degree of
elasticity and hardness requisite to ensure a proper grip to be readily obtained.
The torm which the rubber is caused to assume and the way in which it is securely
fastened into the undercut socket of the gupping jaw will be apparent from
Figure 1^.
The improvement consists in using a short length a of cord rubber formed as
a tube with a very small bore and of an external diameto to just fit within the
nearly cylindrical metal socket in which it is tightly secured by driving a tapered
wooden or other pin c into the bore of the rubber after the lattei has been inserted
in the socket b. The pin beug of considerably larger diameter than the bore
causes the rubber to be squeezed out through the gap between the claw-like jas
of the socket so that, although originally of plain cylindrical form, it projects
sufficiently to ensure that the rubber alone will form the acting gupping face of
the jaw whilst the hard core formed by the pin and the compression to which the
rubber is thereby subjected gives the rubber the internal hardness or resistance
combined with softness and elasticity of the acting face necessary for obtaining
the desired grip.
The next improvement has for its object to enable the rubber gripping jaw to
be dispensed with, especially when the device is to be used in extreme climates.
The dog or jaw is made entirely of metal and engages with recesses formed at
intervals along the bottom of the sash run or with recesses formed in, or projections
fixed against, the face of the sash frame, the gupping lever being variously formed
and mounted on the sash, or the garnish rail, as the case may be. According to
one form, illustrated in face view and sectional plan in the upper part of Figures 2
and 3, the lever d is pivoted to the back of a plate e which 18 fixed to the inner
face of the sash frames over a shallow recess cut therein in which the lever works,
the plate being apertured to give access to the tail end of the lever which is
provided with a thumb knob, flush with the face of the plate, for actuating the
lever and forms a counterweight to throw the gripping surface into operative
engagement with recesses formed in the bottom of the sash run or groove.
another form, shewn in face view and sectional plau in the lower portion of
Figures 2 and 3, the gripping lever d¹ is cranked to allow the jaw to enter the
sash groove and engage in recesses f in the bottom thereof, as before, whilst the
lever is pivoted in a bracket g fixed on and projecting from the inner face of
the sash s', the bracket being so formed as to act as a stop to limit the disengaging
motion of the lover.
In
It will be obvious that as the former of the two arrangements ust described

page_text: permits of the gripping lever being sunk entirely within the thickness of the
sash, such arrangement is well adapted for use either in cases where the window
has only a single sash, or upon the outer sash in cases where a glazed sash and
louvre or shutter aro both used; the second described arrangement which
necessarily projects from the face of the sash being in the latter case only suited
for mounting upon the inner sash although it is equally well adapted to be used
with a single sash. This will be clearly seen from Figures 2 and 3 which shew
both arrangements fitted, the former to the outer and the latter to the inner sash
of a railway carriage window having both a glazed and a louvre sash,
According to another modification, illustrated in face and cross-sectional views
in Figures 4 and 5, the jaw 18 mounted on the garnish rail or other part of the
door frame and bears against the inner face of the sash and in this case,
instead of recesses, projections may be fixed to the face of the sash at intervals
for the jaw to engage with. In this case the bracket in which the lever is
pivoted is adapted to straddle the upper rounded edge of the garnish rail in
such a way as to be self-supporting without straining the screws by which it is
fixed.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The means of fixing a plain cylindrical rubber pad in the socket of the jaw
and causing the acting part of the rubber to project therefrom, consisting of the
combination, with the socket formed as described, of a pad formed of tubular cord
rubber and a pin driven into it so as to fix and expand it as described.
2. The berem described improved sash supporter, consisting in the combination
of a dog or lever of straight or cranked form pivoted to a plate or bracket fixed
to tho sash and of recesses in the bottom of the sash groove or run in which the
dog o lever engages, as specified.
3. The herein described sash supporter, consisting of a dog or lever pivoted in a
bracket mounted on the gainish rail and engaging in recesses or against stiids in or
ou the face of the sash fiame, as specified.
