PROVISIONAL SPECIFICATION.
A New or Improved Cushion for Railway Chairs.
We, ARTHUR TRAVIS CLAY, of Rastrick, Brighouse, Yorkshire, Manufacturer,
and SAMUEL DYSON RHODES, of Spring Gardens, Huddersfield, Yorkshire,
Engineer and Millwright, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to railroads and consists of a new or improved
cushion or pad adapted for use in connection with the chairs in and by which the
lines or rails are secured and supported, our object in such invention being
principally to lessen the vibration and concussion of the rolling stock and the noise
caused by the wheels upon the rails or lines thereby securing greater comfort and
safety in travelling and considerably reducing wear and tear.
In order to carry out our invention we employ blocks of india rubber or other
similar suitable elastic body or material capable of yielding to pressure but
recovering its original bulk on the pressure being withdrawn. These elastic blocks
are made or moulded to the size required and have portions of their upper and
under surfaces countersunk, or slightly raised ribs are formed thereon, in order that
they may more readily adapt themselves to irregularities of surface in contact
therewith, namely, the upper surface of the sleepers and the underside of the
"chairs" between which the said blocks are placed in the form of packing. Holes
are made in said elastic blocks or cushions to allow the bolts, which secure the
chairs to the sleepers, to pass through, and they are firmly secured between the
sleepers and chairs by such bolts.
By mounting the chairs upon elastic or yielding cushions instead of upon the
dead surfaces of the sleepers they, together with the lines or rails supporting them
are made to give slightly when a locomotive or train passes over same, and regain
their original levels on the pressure or weight being withdrawn thereby reducing or
lessening vibration of the locomotive or train especially when running at high
speeds also minimising concussion between the wheels and rails and deadening the
noise created by the wheels as they run over the rails.

COMPLETE SPECIFICATION.
A New or Improved Cushion for Railway Chairs.
We, ARTHUR TRAVIS CLAY, of Rastrick, Brighouse, Yorkshire, Manufacturer,
and SAMUEL DYSON RHODES, of Spring Gardens, Huddersfield, Yorkshire,
Engineer and Millwright, 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 railroads and consists of a new or improved
cushion or pad adapted for use in connection with the chairs in and by which the
lines or rails are secured and supported; our object in such invention being
principally to lessen the vibration and concussion of the rolling stock and the noise
caused by the wheels upon the rails or lines, so as to secure greater comfort and
safety in travelling and to considerably reduce wear and tear.
Such being the nature and object of our invention we will now describe the same
Price 8d1

page_text: more fully, and for that purpose make reference to the annexed sheet of drawings
illustrative thereof.
Fig. 1 shews the application of our improved elastic cushion or pad to the
permanent way of railways.
Fig. 2 is plan view of one construction of our improved elastic cushion or
pad, and
Fig. 3 is cross section of same taken on line a, b.
Referring to Fig. 1, A is the rail or line shewn in cross section, B the "chair
in which the rail is secured and supported in the ordinary manner.
"
Between the chair B and sleeper C is a cushion or pad D composed of india
rubber, or other similar suitable elastic body or material capable of yielding to
pressure and recovering its normal state or condition on the pressure being
removed.
These elastic blocks or cushions are made or moulded to the size required and
may have portions of the upper and under surfaces countersunk or provided with
slightly raised ribs d (see Figs. 2 and 3) in order that they may more readily
adapt themselves to irregularities of surfaces in contact therewith. Holes E are
made in the cushion D through which the ordinary bolts I pass for securing the
chairs to the sleepers, such bolts also securing the cushion between the chair and
sleeper.
Other forms or constructions of cushion or pad than the one shewn may be
employed as found best suited for the purposes of this invention.
By mounting the chairs upon elastic or yielding cushions instead of upon the
dead surfaces of the sleepers they, together with the lines or rails are made to give
slightly when a locomotive or train passes over same, thereby reducing or lessening
vibration of the locomotive or train especially when running at high speeds,
minimising concussion between the wheels and rails, and deadening the noise
created by the wheels as they run over the rails.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
In the permanent way of railways, the application thereto and combination of
elastic cushions or pads such as D to the chairs and rails, in manner and for
purposes substantially as herein set forth.
