IMPROVEMENTS IN RAILWAY CHAIRS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We JOHN MAHONEY of 23 Copley Street, plate layer, PATRICK DOOGAN of
42 Havelock Street, gas maker, and JAMES MAHONEY of. 34 Nicholson Street,
store keeper, all of Leeds in the County of York do hereby declare the naturo
of said invention for "IMPROVEMENTS IN RAILWAY CHAIRS" to be as follows:-
The object of our improvements is to provide a chair and appliances in con-
nection therewith whereby the rails are held firmly in position, so as not to be
loosened by the passing of trains or other rolling bodies over their surfaces.
The rail may be of ordinary construction.
The chair is formed on.one side to receive the rail, and on the other a recess is
provided to receive a metallic block. In the face of the metallic block is provided
a recess to receive a wood piece which projects therefrom, and between it and the
fixed portion of the chair the rail is secured. On the lower portion of the loose
metallic block is provided a projecting piece which is passed in a cavity provided
in the chair and the rail seat, by which arrangement the loose metallic block is
prevented from rising. The metallic block is forced with its wooden piece tight
against the rail by means of a wedge which is forced in between such metallic
block and the raised part of the chair. By these combined arrangements the rail
cannot rise or move laterally, but is held firmly and safely in the chair, being
gripped tightly as above described.
The chair is held down to the sleeper in the ordinary way.

DESCRIPTION OF DRAWINGS.
Fig 1 is a side elevation. Fig 2 a transverse section through A B Fig 1.
Fig 3 a plan looking at the top shewing chair constructed in accordance with our
invention. .
The rail a may be of ordinary construction.
The chair is formed on one side as shewn at b to receive the rail a, and on the
other side a recess c is provided to receive a metallic block d. In the face of
the metallic block d is provided a recess e to receive a wood piece ƒ which projects
therefrom; and between it and the fixed portion of the chair the rail a 15
secured.
On the lower portion of the loose metallic block d is provided a projecting
piece g which is passed in the bevelled recess or cavity.c provided in the chair or
rail seat, by which the loose metallic block d is prevented from rising.
The metallic block d is forced with its wooden piece f tight against the rail a
by means of a wedge h which is passed in between such metallic block & and the
raised part of the chair.

page_text: A wooden block f may also be applied when preferred in the chair at l as shewn
in dotted lines instead of as shewn at f, or the wood block may be applied in both
positions at the same time.
We find that the block or blocks answer it or their purpose much better by
being placed with the grain of the wood endway to the rail. By these combined
arrangements the rail cannot rise or move laterally, but is held firmly and safely
in the chair, being gripped tightly as above described.
The chair is held down to the sleeper in the ordinary way.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
The arrangement and application of metallic block d applied and adjusted
substantially as and for purposes herein set forth.
The arrangement and application of wood piece or pieces f and 1 substantially as
herein set forth.
The combination of the various parts forming the chair substantially as herein
set forth.
