The Invention consists in a compound rail constructed in three parts, preferably of
steel; a central member of 1 section having channelled side members bolted to either
side of its vertical web. The side bars rest upon the foot or base, and extend to the
top of the central web, and form therewith the rail head. They are of similar shape,
at top and bottom, so that they may be reversed when one edge. becomes worn or

I, EDWARD GEORGE CHAMBERLAIN, of San José in the Republic of Costa Rica,
Central America, Engineer, 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 the construction of compound railway rails; and has for
its object to render the rail durable and enable it to be easily repaired.
The Invention consists in a compound rail constructed of three members, as
hereinafter described and claimed.
Reference is to be had to the accompanying drawings forming
a part of this
specification, in which figure 1 is a cross-section taken at the joint of the middle
member of the rail and shewing the fish-plates; and figure 2 is a cross-section
through the three members of the rail shewing one of the intermediate bolts by which
they are united.
Similar figures of reference indicate corresponding parts in both the views.
:
The rail, which is constructed preferably of steel, is composed of three parallel
members vizt. a central member 1 having a flanged base 2 and clamped between
channeled side members 3 by means of a number of bolts 5 and nuts 6. The side
members 3 rest upon the base 2 and extend to the top of the central web 1 and form
therewith an even surface for the head of the rail. They are of similar shape at top
and bottom, so that they may be reversed when one edge becomes worn or injured,
and have a longitudinal channel or groove 7 in their outer faces to receive the fish-
plates 4 at the joints and the heads and nuts 5 and 6 of the intermediate bolts. To
form a continuous rail and prevent "pounding" of the car wheels, the central and
side members may overlap or "break joint,” that is to say, the central member 1
projects beyond the side members 3 whilst at the adjacent end of the abutting rail
the side members 3 project beyond the central member 1 so as to overlap the central
member 1 of the first mentioned rail, the overlapping parts at the joints being clamped
between fish plates 4 by bolts 5 and nuts 6. If desired, the members 3 may be
arranged to break joint midway of the central member 1 and form therewith a
continuous rail.
The rail above described can be readily repaired, if one of the parts break, by
substituting a new part in lieu thereof.
The rail is light for transportation as it can be handled in sections, is durable
as it is compactly made, and will last longer than other rails as it is reversible.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. A compound railway rail, consisting of a central longitudinal member having
a flanged base and reversible-side-members bolted thereto at either side and having

page_text: their lower edges resting entirely on flanges of the central member the central and
side members having their upper edges even to form the head of the compound rail,
substantially as shewn and described.
2. A compound railway rail, consisting of the central member 1 with flanged
base 2 and reversible side members 3 with channeled outer faces to receive the fish-
plates and bolts by which the members 3 and 1 are bolted together to form a head
for the rail, substantially as described.
