PROVISIONAL SPECIFICATION.
An Improved Process for the Manufacture of Railway Spikes.
A communication to me from HEINRIOH RUMPF, of Dahlhausen, on the Ruhr,
in the Empire of Germany, Manufacturer.
I, EDMUND EDWARDS, of the Fum of Edwards and Co., Patent Agents and
Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows
The manufacture of railway spikes has been heretofore effected by hand or by
the help of machines; this process has, however, not only been expensive, but has
occupied much time.
The improved process hereinafter described, obviates these inconveniences by
first rolling double bar-iron of the desired section, then separating the same longi-
tudinally, and finally transversely cutting the bars thus separated longitudinally,
so as to form spikes.
In Figures 1 to 4 (of the accompanying drawing) different forms of transverse
sections of such bar iron are represented. After rolling, the iron is cut through
longitudinally, along the line x―x, whereby two rods of the desired section are
obtained.
These rods are then cut transversely to spikes. For such cutting any contrivance
may be used; but the process will be most conveniently and quickly performed by
means of ordinary plate shears. The process described may, however, be altered
In such manner, that the double bar iron is first separated transversely into pieces,
which are then separated longitudinally.
From the manufacture in the way described of railway spikes from double bar-
iron a considerable advantage is obtained First, the iron is more easy to roll, and
much time is saved, as at each cut two spikes are turned out, and they are more
easily cut from double bar iron, because the iron is of the same section on both
sides of the centre line, whereas in rolled iron having the section of one spike only,
In consequence of the unequal thickness of the metal, the cut is also unequal, and
the cutting of the spikes becomes difficult.

An Improved Process for the Manufacture of Railway Spikes.
A communication to me from HEINRICH RUMPF, of Dahlhausen, on the Ruhr,
in the Empire of Germany, Manufacturer.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Patent Agents and
Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, 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, and
accompanying drawing, that is to say :—
The manufacture of railway spikes has been heretofore effected by hand or by

page_text: the help of machines, this process has, however, not only been expensive, but has
occupied much time
-
The improved process hereinafter descubed obviates these conveniences, by
first rolling double bar-iron of the desired section, then separating the same longi-
tudinally, and finally transversely cutting the bars thus separated longitudinally,
FO as to form spikes.
}
In Figures 1 to 4 of the accompanying drawing, different forms of transversc
sections of such bar non are represented. After rolling, the iron is out through
longitudinally, along the line -, whereby two rods of the desned section are
obtained
These rods are theu cut transversely to form spikes. For such cutting any
contrivance may be used, but the process will be most conveniently and quickly
performed by means of suitable plate shears. The process described may, however,
be altered in such manner, that the double bai-non 18 fist separated transversely
into pieces, which are then separated longitudinally.
From the manufacture in the way described of railway spikes from double bai-
on a considerable advantage is obtained. First, the non is more easy to roll, and
much time is saved, as at each cut two spikes are turned out, and they are more
easily cut from double bar 11on, because the non is of the same section on both
sides of the centre line; whereas in rolled on having the section of one spike
only, in consequence of the unequal thickness of the metal, the cut is also unequal,
and the cutting of the spikes becomes difficult.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.-
The improved process for the manufacture of railway spikes, consisting in rolling
double bar iron of the desired section; then cutting through and separating the
same longitudinally, and finally cutting transversely the bars thus formed so as to
forin spikes of the required shape, substantially as described and illustrated.
