1 WILLIAM EDWIN HEATH of 46 Fairmead Road Islington Engineer do hereby
declare the nature of this invention to be as follows:-
This invention is intended more particularly to be used with the rails described in
the provisional specification lodged with application for Patent A.D. 1887 No. 1311.
The rail is formed in two parts the lower rail preferably of a tee form for laying
on sleepers or concrete, the upper rail is made with a single flange or web on the lower
side the rolling surface is rolled to the desired section. On the inner surfaces grooves
are formed in both parts opposite each other preferably of a semicircular section and
into these grooves between the metal surfaces is placed a packing of either wire hemp
wood or other suitable material preferably tarred rope and bolted tightly between the
metals making the road elastic and preventing noise.

I WILLIAM EDWIN HEATH of 46 Fairmead Road, Islington, 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 is intended to be used with the description of rails for which a
Patent has been granted to me and numbered 1311, 1887, the rail is formed as therein
described so that the use of fish plates for connecting the rails is obviated, the bottom
rail being really the fish plate for the upper rail, as one continuous upper metal runs
over and secures the joint in the lower metal.
In the accompanying drawing figure 1 shows a double headed rail for Railways,
and figure 2 a rail for Tramways.
U.,
I form in both sections, as shown in the accompanying drawing at 1. a, and 2
recesses or grooves rolled in the rail, in to these grooves 1 firmly calk or insert a flexible
or yielding material preferably of hemp, but it may be any other suitable substance.
The point of the lower rail in figure 2, and of the upper and lower rail in figure 1, I
insert in these grooves, which bearing on the flexible material and taking the weight
of the carriage or rolling stock prevents sound and vibration.
I do not confine myself to the precise forms or sections of rails shown, which may
be varied to suit circumstances.
Before inserting the yielding material I coat the grooves with tar or grease or
other similar substance, and after the insertion of the yielding material I also coat it
in the same way, to exclude wet and atmospheric influence.
Before inserting the tie bolts shown at 1. B, and 2. B, I bring the two parts of the
rail into position by powerful cramps.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is :-
For Rails on Railways or Tramways intended for carriages of any description to
roll on and for other purposes, the insertion in grooves between the upper and lower
portions of the rail of a packing of yielding material as before described and illustrated
in the accompanying drawing."
