IMPROVEMENTS IN PERMANENT WAY OF RAILWAYS AND TRAMWAYS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We JOSEPH Coox of 707 Duke Street, Glasgow, in the County of Lanark,
Steel Worker, and DANIEL ATKINSON, of 7 Foster Street, Wednesbury, in the
County of Stafford, Forger, do hereby declare the nature of our said Invention
for "IMPROVEMENTS IN PERMANENT WAY OF RAILWAYS AND TRAMWAYS"; to be
as follows:-
This Invention, which relates to improvements in permanent way of railways
and tramways, has special reference to the construction of the chairs by which the
rails are secured.
The improved chairs, which are specially adapted for use in lieu of fish-plates,
to secure the rails at their end joints, are cast or formed with a broad check or jaw
to fit the rail at one side, and with a pair of brackets which rise vertically from
the base of the chair at the opposite side of the rail, but which are at a sufficient
distance from the opposite cheek or jaw to allow of the rail being freely fitted in
between them. Between the two brackets at this side of the rail is titted a plate
or cushion which may be made of metal or hard wood, and which is shaped to fit
the web and lower flange of the rail, and this plate or cushion is kept in place
bearing hard against the side of the rail or rails, by means of a wedge or slightly
tapered key which is passed through a slot in each of the brackets and bears on the
back of the cushion. This wedge or key, which lies horizontally and parallel, or
nearly so, to the rail, is prevented from shaking out by means of a split pin or
similar device fitted into it after it is driven in tight. When applied to secure the
end joints of the rails, pins are formed on the cushion, or passed through the web
of the rail into the cheek of the chair, to prevent the rails " creeping" out of
the chair.
The improved chair described may be adapted for any section of rail. We prefer
however to use a section of rail having no lower flange, and in that case the chairs
are cast or formed with cheeks or jaws which fit the rail on both sides, and the rail
is prevented from rising or creeping by passing pins or bolts through the chair and
the web of the rail.

Steel Worker, and DANIEL ATKINSON, of 7 Foster Street, Wednesbury, in the
County of Stafford, Forger, do hereby declare the nature of our said Invention for
"IMPROVEMENTS IN PERMANENT WAY OF RAILWAYS AND TRAMWAYS," and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
Our Invention, which relates to improvements in permanent way of railways
and tramways, has special reference to the construction of the chairs by which the
rails are secured.
. same.
Our Invention is illustrated by the accompanying Drawings, in which Figure 1
is an elevation of a modification of our improved chair as adapted for railway
purposes, and for securing the ordinary form of rail. Figure 2 is a plan of the
Figure 3 is an elevation of a modified form of chair adapted for use in
securing rails having no lower flange, and Figure 4 is a plan of the same.
Figures 5 and 6 are respectively an elevation and a plan of a form of chair adapted
for securing tramway rails, the rail in this case also being formed without a lower
flange. Figures 7 and 8 are an end and a side elevation of the cushion or key
employed in fixing the rail in the chair.
The improved chair illustrated in Figures 1 and 2 is specially adopted for use in
lieu of fish-plates, to secure the rails R at their end joints, and is cast or formed
with a broad cheek or jaw A to fit the rail at one side, and with a pair of
brackets A¹ which rise vertically from the base of the chair at the opposite side of
the rail, but which are at a sufficient distance from the opposite cheek or jaw A to
allow of the rail R being freely fitted in between them. Between the two
brackets A¹ at this side of the rail is fitted a plate or cushion B, which may be
made of metal or hard wood, and which is shaped to fit the web and lower flange
of the rail R; and this plate or cushion is kept in place bearing hard against the
side of the rail or rails, by means of a wedge or slightly tapered key C which is
passed through a slot C¹ in each of the brackets and bears on the back of the
cushion B. This wedge or key, which lics horizontally and parallel or nearly so to
the rail, is prevented from shaking out by means of a split pin c or similar device
fitted into it after it is driven in tight. When applied to secure the end joints of
the rails, as shown in these Figures, pins D are formed on the cushion, and are
passed through the web of the rail R into the cheek A of the chair to prevent the
rails "creeping" out of the chair.
The improved chair described may be adapted for any section of rail. We prefer
however to use a section of rail having no lower flange, as shown in Figures 3 and 4,
and in that case the chairs are cast or formed with cheeks or jaws A, A', which fit
the rail R on both sides, and the rail R is prevented from rising or creeping by
passing pins or bolts through the chair and the web of the rail.
The chair shown in Figures 3 and 4 is intended for securing the rail at any part
of its length but the end joints, and is therefore made narrower than that shown in
Figures 1 and 2; In lieu of forming the pins (D) to prevent the 'rail rising, a bead
or feather d is rolled on the web of the rail, and a corresponding cheek is made in
the cushion B to hold the rail in place.
The chair shown in Figures 5 and 6 for securing tramway rails is similar in
construction to those already described, but is formed with broad bearing surfaces
on the top of each cheek or jaw A, A³ to support the flange of the rail.

page_text: 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,
First. The combination of parts forming the improved chairs for permanent way
of railways and tramways, substantially as herein described and illustrated.
Second. The combination of the chair and cushion fitted between brackets
formed on the chair and secured by a key passing through such brackets,
substantially as herein described and illustrated.
