An Improvement in Railway and other Carriage Window Sashes.
I, EDWARD JACOB HILL, of 11, Victoria Street, in the City of Westminster, Civil
Engineer and VINCENT WALKER HILL, of The Hull, Barnsley and West Riding
Junction Railway and Dock Company's Offices, Hull in the County of York,
Secretary and General Manager, do hereby declare the nature of this invention to
he as follows:-
This invention relates to an improvement in raising railway and other carriage
window sashes by means of the strap generally used for the purpose.
As such straps are now attached to the lower cross rail of the sash it is necessary in
order to raise the sash to a sufficient height to enable it to be pushed outwards over
the fence rail to first partially raise the sash by a pull on the strap exerted on an
approximately horizontal direction on the strap after it passes over the garnish rail
roller, and then to raise it still further by a second direct pull exerted on the strap
in the upward direction after the strap has been raised completely off the garnish
rail roller.
The necessity of applying two distinct pulls to the strap in different directions
involves the shifting of the hand in order to change the direction in which the
pull is exerted which is troublesome and also annoying since unless the strap is
firmly held it is apt to slip and allow the sash to fall again to the fully open position.
In effecting the reverse movement it is also necessary to lift the sash inwards over
the fence rail by a direct upward pull which is less convenient to exert than a pull
in the horizontal direction.
The object of my invention is to enable the sash to be at once raised to the full
height necessary to pass it over the fence rail by a single indirect pull exerted on the
strap in the horizontal direction without requiring the strap to be lifted off the garnish
rail or any second or further effort to be exerted in order to maintain it at the height
to which it has been raised except that of pushing the sash outwards over the fence
rail in the usual way. Similarly it has for object to enable the sash to be lifted
inwards over the fence rail for the purpose of lowering by a pull in the horizontal
direction exerted on the strap after it passes over the garnish rail roller.
According to my invention the strap is attached not directly to the face of the sash,
as usual, but to a bracket which projects downwards from the lower edge of the sash
such a distance that the bottom of the sash when raised by the pull of the strap
passing over the garnish rail roller in the usual way will rise above the level of the
fence rail. This bracket is formed of a flanged plate adapted to embrace the face and
lower edge of the sash in the forner of which it is countersunk as usual and to which
it is secured by screws both in the face and lower edge flange of the plate. This
plate has a pair of downwardly extending arms in which the pin on which the
strap is hinged or threaded is fixed and is suitably strengthened to resist the strains
to which it is subjected.
As the bracket projects downwards so far that the strap when the sash: is raised to
the highest possible position must always pass in the upward direction from its point
of attachment in order to pass over the garnish rail roller, it follows that a pull
exerted on the other end of the strap in the horizontal direction will always suffice to
aise the sash high enough to pass over the fence rail and as the tendency of the strap

page_text: is to draw the sash towards the garnish rail such a pull is sufficient to lift the sash
inwards over the fence rail for the purpose of lowering the sash.

COMPLETE SPECIFICATION.
An Improvement in Railway and other Carriage Window Sashes.
We, EDWARD JACOB HILL of 11, Victoria Street, in the City of Westminster,
Civil Engineer, and VINCENT WALKER HILL formerly of The Hull Barnsley and
West Riding Junction Railway and Dock Company's Offices, Hull, in the County
of York, Secretary and General Manager and now of the Constitutional Club,
Northumberland Avenue, London, S.W., 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 :-
This invention relates to an improvement in means of raising railway and other
carriage window sashes. For this purpose a strap is generally attached to the
lower cross rail of the sash and as such strap is now attached it is necessary (in
order to raise the sash to a sufficient height to enable it to be pushed outwards
over the fence rail) to first partially raise the sash by a pull exerted in an
approximately horizontal direction on the free end of the strap which has passed
over the garnish rail roller and then to raise it still further by a second direct
pull exerted on the strap close up to tho sash in the upward direction after the
strap has been raised completely off the garnish rail roller.
The necessity of applying two distinct pulls to the strap in different directions
involves the shifting of the hand in order to change the direction in which the pull
is exerted, which is troublesome and also annoying since unless the strap is firmly
held it is apt to slip and allow the sash to completely fall again. In effecting the
reverse movement it is also necessary to lift the sash inwards over the fence rail
by a direct upward pull on the strap which is less convenient to exert than a pull
in the horizontal direction.
The object of our invention is to enable the sash to be at once raised to the
full height necessary to pass it over the fence rail by a single indirect pull exerted
on the strap in the horizontal direction without requiring the strap to be lifted off
the garnish rail or any second or further effort to be exerted in order to maintain
it at the height to which it has been raised the only further operation necessary
being that of pushing the sash outwards over the fence rail in the usual way.
Similarly it has for object to avoid the necessity of first lifting the sash inwards over
the fence rail by a direct upward pull in order to lower the sash and to enable the
sash to be lifted inwards over the fence rail by a pull in the horizontal direction
exerted on the strap after it has passed over the garnish rail roller.
Our invention is illustrated in the accompanying drawings forming part of this
specification wherein
Figure 1 is a face view and Figure 2 a vertical section of the strap attachment as
applied to the sash.
Figures 3 and 4 are sectional views of the door showing the sash in the lowered and
raised positions respectively.
The same letters of reference denote like parts in all the figures.
According to our invention the strap A is attached not directly to the inner face of
the lower cross bar of the sash as usual but to a bracket B which has two limbs C that
project downwards from the lower edge of the sash S so that when a pull is applied in
the horizontal direction to the free end of the strap the sash will be raised wholly
above the level of the fence rail f. This bracket is formed of a plate B of angled

page_text: section adapted to be screwed against the face of the sash and having a flange b
which is screwed against the lower edge of the sash as shewn. This plate has a
pair of downwardly extending arms C in which is fixed the pin D to which the
looped end of the strap A is attached.
As the bracket projects downwards so far below the bottom of the sash that
the attachment pin D of the strap when the sash is raised to the highest possible
position must always remain below the roller r on the garnish rail g, it follows that
a pull exerted on the free end of the strap in the horizontal direction will be
transmitted as a pull in the upward direction to the pin D and will therefore
always suffice to raise the sash high enough to enable the usual angle plates at
the bottom of the sash to be passed over the fence rail f. As the tendency of the
strap is to draw the sash towards the garnish rail g a pull on the strap in the
horizontal direction is sufficient to lift the sash inwards over the fence rail when it
is desired to lower the sash.
By fixing the flange 6 of the plate B to the angle plates the tendency of the strain
to split the wood of the sash is prevented and the same end may be attained by
casting the bracket B and angle plate s in one or by rivetting them together before
affixing to the sash. The downwardly projecting bracket arms C are protected
from injury when the sash is allowed to drop by providing the usual rubber buffers E
for the sash to drop on to.
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
The berein described means of attaching the strap to a railway or other carriage
window sash, consisting of a downwardly projecting bracket adapted to bring the
point of attachment of the strap such a distance below the sash as to be always below
the upper edge of the garnish rail and provided with means of attachment to the face
and lower edge of the sash, substantially as described.
