Inspector both of Prince's Foundry, Ramsbottom in the County of Lancaster, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in rail chairs and couplings for permanent
ways and has for its object to provide means which will serve to secure the rail in the
chair in its continuity, as well as at the ends or points of junction of the same, thus
acting as a coupling at the same time.
The nature and novelty of this invention consists in forming the inner side of the
jaw of the chair, against which the customary wooden wedge is driven, with two
inclined surfaces, & employing between the said inclined surfaces and the rail (or rail
ends when serving as a coupling) two wedges, suitably arranged in a line so as to be
forced towards each other by suitable means.
The said wedges may be made of any suitable material and drawn or driven
towards each other, by means of a bolt passing through the same, and lock-nut, or
cottar or wedges.

page_text: Improvements in Rail Chairs and Couplings for Permanent Ways.
We JOSEPH STRANG, Engineer and JOHN HENRY PINDER, Permanent Way
Inspector, both of Prince's Foundry, Ramsbottom, in the County of Lancashire, 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 improvements in rail chairs and couplings for permanent
ways and has for its object to provide means which will serve to secure the rail in the
chair in its continuity, as well as at the ends or points of junction of the same, thus
acting as a coupling at the same time.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is an end view, and Fig. 2 a plan, of a-single chair, and Fig. 3 a plan of a
joint chair according to our invention.
A is the base of the chair, the sleeper, and b the rail.
In carrying out our invention and referring to Figs. 1 & 2, the improvements
consist in forming the inner side of the jaw a of the chair, against which the
customary wooden wedge is driven, with two inclined surfaces a¹, and employing
between the said inclined surfaces a' and the rail b (or rail ends, when serving as
a coupling, see Fig. 3) two wedges c, suitably arranged in a line so as to be forced
towards each other by suitable means.
The said wedges may be made of any suitable material, preferably of cast iron or
steel and drawn or driven towards each other by means of a bolt d passing through
the same, and lock-nut, or cottar or wedges if deemed necessary.
As will be readily understood from the drawing, our improvements will be equally
applicable for a single as well as a joint chair, in the latter case, however, the width
of the chair A and length of the wedges c would be proportionally increased and one
of the wedges c caused to overlap the rail ends so as to give the same a firm hold in
the chair A, the wedges c being in both cases prevented from lateral and vertical
deflection by means of the bolt d.
Having now particularly described and ascertained the nature of our invention and
in what manner the same is to be performed, we declare that what we claim is :-
In single or joint rail chairs for permanent ways; the inclines a¹ formed on the
inner face of the jaw a in combination with two wedges e employed in a line. with
each other between the said inclines a¹ and the side of the rail (or rail ends b¹), and
drawn or driven together by means of a bolt d or its equivalent, substantially as and
for the purpose hereinbefore specified.
