Improvements in the Construction of Tramway and like Rails.
I, LEONARD COOPER, of Central Bank Chambers, Leeds, in the County of York,
Iron Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the construction of tramway
and like rails, in which there is a groove formed in the rail for the reception
of the wheel flanges; and has for its object, the construction of the rails in such
a manner that, after the rail has been in use and the tread of the rail worn, or
the groove worn to a greater width than is desirable; the worn portion may be
detached and replaced by a new portion without having occasion to provide an
entirely new rail, as is the case with rails constructed in the usual manner.
As is well known, the portions of the rail subjected to the most severe usage
are the tread, and the inside of, the groove when the rail is laid on the curve, in
which case the flanges of the wheels cut away the material, thereby making the
groove wider especially when the curve is of short radius.
In carrying out my object, the rails are rolled in two sections, a portion of the
groove being in both sections, also a bottom flange on both sections, the two
sections are secured together by bolts or the like, thus forming a complete rail
so arranged that on one portion of the rail becoming worn, it may be replaced by
another without having to discard the whole rail, and thus by these means to
reduce the cost of maintenance of the permanent way.

Improvements in the Construction of Tramway and like Rails.
I, LEONARD COOPER, of Central Bank Chambers, Leeds, in the County of York,
Iron Merchant, 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 certain improvements in the construction of tramway
and like rails, in which there is a groove for the reception of the flanges of the
wheels; and has for its object, the construction of the rails in such a manner that,
after the rail has been in use and the tread of the rail worn, or the groove worn
to a greater width than is desirable, the worn portion may be detached and
replaced by a new portion without having occasion to provide an entirely new
rail, as is the case with rails constructed in the usual manner.

page_text: As is well known, the portions of the rail subjected to the most severe usage,
are the tread, and the inside of the groove when the rail is laid on the curve, in
which case the flanges of the wheels cut away the material, thereby making the
groove wider than is desirable, more especially is such the case when the curve
of the rails of the permanent way is of short radius.
In order that my invention may be fully understood, I will describe the same
in detail by making reference to the accompanying sheet of drawings, in which
Fig. 1 represents an elevation of a short length of rail constructed in accordance
with my improvement, and Fig. 2 is a cross section of the same on line a b.
The rail is rolled in two sections A and A¹, a portion of the groove B being
formed in each section, also on each section a portion of the bottom or base
flange C is formed. The two sections rolled to the configuration described, are
secured together by bolts or the like D, thus forming a complete rail in such a
manner that, on one portion Å or A¹ becoming worn, such worn
section may be removed or replaced by a new section without having
to discard the whole rail, as is the case with rails constructed in the
ordinary manner; thereby considerably reducing the cost of maintenance of the
permanent way.
Having now particularly described and ascertained the nature of my
invention, and in what manner the same is to be performed, I declare that what
I claim is:
A tramway or like rail rolled in two sections A and A¹, each section having a
portion of the groove B and bottom flange C formed thereon in a manner that
on the two sections being secured together by bolts or the like D, a complete
rail is formed substantially in the manner and for the purpose as herein before
described and illustrated.
