Improvements in Railway Carriage and other Sash Windows.
EDWARD JACOB HILL, of 11, Victoria Street, in the City of Westminster,
Civil Engineer, and VINCENT WALKER HILL, of The Constitutional Club, North-
umberland Avenue, London, Gentleman, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improvement in the apparatus for raising railway
carriage and other sash windows, for which former application for Letters Patent
numbered 24,830 of 1897 was made, consisting essentially of a bar or flap hinged
to the lower edge of the sash and a strap attached to the said flap or bar so that by
the upward pull of the strap in the act of raising the sash will cause the latter
to be automatically moved outwards over the "fence" rail when it reaches its
fully raised position, the sash being thus raised and moved outwards over the
fence"
rail by a continuous pull of the strap applied by one hand without the
necessity of using the other hand to force the sash outwards over the edge of
the strip which rises from the surface of the "fence" rail.
66
The object of the present invention is to enable the sash to be disengaged from
the fence" rail and to lowered under the control of one hand with the same
facility as in raising it and it consists in the employment of an auxiliary strap
whose function is to enable the sash to be disengaged from the flange or strip on
the "fence" rail and to be pulled inwards for the purpose of being, lowered under
the control of the main strap or of being allowed to fall suddenly. This auxiliary
strap is attached directly to the lower bar of the sash itself or to the upper edge of
the hinged bar in such manner that a pull on the auxiliary strap will tend to cause
the sash and hinged bar to lie in the same vertical plane and so that the auxiliary
strap will lie upon the main strap as it passes over the roller on the garnish rail
in such a position that both straps may be readily grasped together. The auxiliary
strap is preferably attached to the main strap by passing through a loop on the
latter and it terminates in a rigid tab or enlargement constituting a stop to prevent
the auxiliary strap being drawn out of the loop and as a hand-hold by which the
pull may be applied wholly or principally to the auxiliary strap when both straps
are lightly grasped at once for the purpose of lifting the sash inwards over the
rail. In thus operating the hand is allowed to slip along the straps until the tab
or enlargement comes within the grasp so that by gripping it laterally sufficient
strain can be put on the auxiliary strap to lift the sash inwards over the "fence"
rail, which done the main strap remains in the grasp of the hand for controlling
the further lowering of the sash.

We, EDWARD JACOB HILL, of 11, Victoria Street, in the City of Westminster,
Civil Engineer, and VINCENT WALKER HILL, of The Constitutional Club, North-
umberland Avenue, London, 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 the means for raising railway
carriage and other similar windows (forming the subject of an application for
Letters Patent numbered 24,830 of 1897) consisting essentially of a toggle bar or
flap hinged to the lower edge of the sash and a lifting strap attached to the toggle
flap or bar so that the upward pull of the strap will cause the sash to be moved
outwards over the "fence" rail when it reaches its fully raised position, the sash
being thus raised and moved outwards over the "fence" rail by a continuous pull
of the strap without the necessity of using the hand to apply pressure to force the
sash outwards.
"
The object of the present invention is to enable the sash to be disengaged from
the "fence" rail and to be lowered with like facility under the control of one hand
and the invention consists in the employment of an auxiliary strap whose function
is to enable the sash to be disengaged from the flange of the "fence" rail and to
be pulled inwards for the purpose of being lowered. This auxiliary strap is
attached directly to the sash itself or to the toggle bar so that an upward pull on
the auxiliary strap will tend to raise the sash and disengage it from the "fence"
rail, the auxiliary strap lying upon the main strap as it passes over the "garnish"
rail so that both straps may be readily grasped together. The auxiliary strap
is preferably passed through a loop on the main strap and it terminates in a rigid
tab or enlargement constituting a stop and serving as a hand-hold to enable the
strain to be applied mainly to the auxiliary strap when both straps are lightly
grasped at once.for the purpose of lifting the sash inwards over the rail. In thus
operating the hand is allowed to slip along the straps until the tab or enlargement
comes within the grasp so that by gripping it laterally sufficient strain can be put
on the auxiliary strap to lift the sash inwards over the "fence" rail which done
the main strap remains in the grasp of the hand for controlling the further
lowering of the sash.
The invention is illustrated in the accompanying drawings forming part of this
specification wherein Figures 1 and 2 are a vertical cross section and inside face
view of the lower part of a railway carriage door the window being in the fully
raised position.
A is the sash, B a toggle bar or flap hinged at a to the lower edge of the sash A,
and C the sash-lifting strap attached to the toggle bar as in my previous application
above referred to, so that by the mere pull of the strap C the flap or bar B is
caused to assume the inclined position shewn in Figure 1 so that in consequence
of its end tenons B¹ bearing against the side of the sash grooves E in which they
are engaged, the bar is caused to act as a toggle tending by its thrust to force
the sash A outwards over the "fence" rail D when the sash is completely raised.
The strap C is attached to the lower edge of the bar B as at e and passes up over
the usual roller g on the "garnish" rail G. The lower edge of the sash A is shod
with the usual angle iron strip A¹, the downwardly projecting flange of which
engages with the usual upwardly projecting edge of a metal strip F1 fixed to the
6h
fence "rail D.
I is the auxiliary strap of the present invention. It is shewn as attached by a
screw plate i directly to the upper edge of the bar B and lies in a notch in the joint-

page_text: This
covering lip 6 of the bar B. It might, however be attached to the sash itself,
and in either case it lies upon the strap C as it passes over the roller.
auxiliary strap is preferably slipped through a loop C attached to the lifting
strap C (but it might be entirely loose) and it terminates in a stiff leather tab C³
which serves as a stop and hand-hold. This strap I is intended to be used for
lifting the sash A inwards over the "fence" rail flange for the purpose of lowering
it which may conveniently be done by grasping both straps C and I together
and allowing them to slip until the tab C3 comes within the grasp of the hand
sufficiently to enable the strain to be mainly applied to the strap I for the purpose
of lifting the sash inwards whilst the retention of the hold on the strap C enables
the lowering of the sash to be controlled.
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 combination with a railway carriage or other window sash provided with a
toggle bar hinged thereto and a lifting strap attached to the toggle bar so as by
its pull to cause the bar to act as described, of means consisting of an auxiliary
strap applied substantially as described for lifting the sash inwards over the
'fence rail previous to lowering.
