PROVISIONAL SPECIFICATION.
Improvements in Cushioning Devices for Sliding Windows and
Ventilators of Railway and other Carriages.
We, RICHARD PEARCE, of 5 Church Road, Howrah, Bengal, India, Carriage
and Wagon Superintendent, and JOHN CHARLES TAITE of 63 Queen Victoria
Street, in the City of London, Engineer, do hereby declare the nature of this
invention to be as follows:-
-
This invention has reference to inproved constructions of cushioning devices for
supporting the sliding windows and jil mills or ventilators of the louvre type
(hereinafter referred to as ventilators) of railway and other carriages when they
are in their opened position, and also to cushioning devices for preventing the
rattling of such windows and ventilators when they are in their closed position, the
objects being to render such cushioning devices more efficient and durable than
heretofore.
For this purpose, a cushioning device according to this invention consists of a
perforated block of india rubber having large, fat, and oppositely arranged hearing
surfaces, and centrally arranged reduced end portions that are adapted to be
detachably secured to a carrying rail, or to be fixed in the edge of a window or
ventilator frame, according to the purpose for which it is to be used, the thickness
of the said end portions being such that the bearing surfaces on the intermediate
portion or portions of the block extend beyond them on each side.
In one construction the intermediate or enlarged part of the block is of rect-
angular form in cross-section and of approximately rectangular form but with
rounded corners, in side view, and is formed with horizontal holes of circular form
in cross section to increase its resiliency.
In a modified construction, the holes are in the form of horizontal slots.
In another construction, the cushioning device consists of two or more perforated
intermediate blocks connected by one or more narrow neck portions that may be of
the same thickness as the reduced end portions.
Where the cushioning device is to be used as a support or rest for a sliding
window or ventilator, the reduced end portions, and it may be also the intermediate
neck portion or portions when used, are formed with screw holes to permit of the
device being detachably connected to a carrying rail so that when one bearing or
supporting surface has become worn and rendered inefficient, the block can be
readily reversed in position to enable the other bearing or supporting surface to be
brought into use.
Where the cushioning device is to be used to prevent rattling of a window or
ventilator, the reduced end portions are made of such a shape at their free ends, as
for example of vee-shape, as seen in side view, that they can be forced laterally
into correspondingly formed recesses in the edge of the window or other frame, so
that the said devices will be prevented from becoming accidentally displaced in a
sideways direction.

Ventilators of Railway and other Carriages.
We, RICHARD PEARCE, of 5 Church Road, Howrah, Bengal, India, Carriage
and Wagon Superintendent, and JOHN CHARLES TAITE, of 63 Queen Victoria
Street, in the City of London, 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:-
This invention has reference to improved constructions of cushioning devices for
supporting the sliding windows and jil mills or ventilators of the louvre type
(hereinafter referred to as ventilators) of railway and other carriages when they
are in their opened position, and also to cushioning devices for preventing the
rattling of such windows and ventilators when they are in their closed position, the
objects being to render such cushioning devices more efficient and durable than
heretofore.
For this purpose, a cushioning device according to this invention consists of a
perforated block of india rubber having large, flat, and oppositely arranged bearing
surfaces, and centrally arranged reduced end portions that are adapted to be
detachably secured to a carrying rail, or to be fixed in the edge of a window or
ventilator frame, according to the purpose for which it is to be used, the thickness
of the said end portions being such that the bearing surfaces on the intermediate
portion or portions of the block extend beyond them on each side.
Fig. 1 of the accompanying drawings shows in side view one construction of
cushioning device according to this invention applied to a carrying rail, and
Fig. 2 is a plan of the device alone.
In this construction the intermediate or enlarged part 1 of the block of india
rubber, having two oppositely arranged flat bearing surfaces 1ª, is of rectangular
form in cross-section and of approximately rectangular form, but with rounded
corners 1, in side view, and is formed with horizontal holes 2 of circular shape
in cross-section to increase its resiliency. 3 are the centrally arranged reduced
end portions.
Figs. 3 and 4 show in side view and plan, a slightly modified construction in
which the holes 2 are in the form of horizontal slots.
Figs. 5 and 6 show in side view and plan, another modified construction in which
the cushioning device consists of two perforated intermediate portions 1, 1 connected
by a narrow neck portion 4 which may, as shown, be of the same thickness as the
reduced end portions 3.
Where the cushioning device is to be used as a support or rest for a sliding
window 5 or ventilator 6, as shown in Fig. 7, which is a cross-section of a
railway carriage door drawn to a smaller scale than the remaining figures, the
reduced end portions 3, and it may be also the intermediate neck portion 4 (or
portions) when used, are formed with screw holes 3 to permit of the device being
detachably connected by screws 7, (Fig. 1) to a carrying rail 8 so that when the
bearing or supporting surface or surfaces 1 at one side of the block has or have
become worn and rendered inefficient, the block can be readily reversed in position
to enable the bearing or supporting surface or surfaces at the opposite side of the
block to be brought into use.
Where the cushioning device is to be used to prevent rattling of a window or
ventilator, the reduced end portions 3 are made of such a shape at their free ends,
as for example of vee-shape as seen in side view, that they can be forced laterally
into correspondingly formed recesses in the edge of the window or other frame, so

page_text: that the said devices will be prevented from becoming accidentally displaced in a
sideways direction.
Figs. 8 and 9 are respectively edge and side views showing a cushioning device
of the kind represented in Figs. 1 and 2, but having vee-shaped reduced ends and
no screw holes, thus applied to the edge of a sliding window 5. Figs. 10 and 11,
and Figs. 12 and 13 are similar views to Figs. 8 and 9, showing the application to
windows of similarly modified forms of the cushioning devices shown in Figs. 3
and 4, and Figs. 5 and 6 respectively. Cushioning devices thus applied to a sliding
window and to ventilators, are shown at 1* in Fig. 7.
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. A cushioning device consisting of a perforated block of india rubber having
large flat and oppositely arranged bearing surfaces and reduced end portions that
are adapted to be detachably secured to a carrying rail, or to be fixed in the edge
of a window or ventilator frame, the thickness of the said end portions being such
that the bearing surfaces on the intermediate portion or portions of the block extend
beyond them on each side, substantially as described and shown for the purpose
specified.
2. The improved cushioning devices herein before described with reference to and
shown in Figs. 1 and 2; in Figs. 3 and 4 and in Figs. 5 and 6, or modified according
to Figs. 8 to 13 inclusive of the drawings annexed.
