Shapes from Rails or other Forms of Metal, and in
Apparatus therefor.
I LOUIS MANNSTAEDT of. Kalk near Cologne in the German Empire Director
of the Humboldt Rolling Mills at that place do hereby declare the nature of
my invention for IMPROVEMENTS IN THE FORMING OF METAL RODS, PLATES OR
OTHER SHAPES FROM RAILS OR OTHER FORMS OF METAL AND IN APPARATUS
THEREFOR to be as follows:-
The object of the invention is to enable the rails produced for railway use and
other forms of metal to be utilized for other purposes by cutting and rolling or
forming such rails or forms of. metal whilst in a cold state into rods, plates strips
or other desired shapes for reuse and in apparatus therefor.
By these means forms existent of metal such particularly as rails for railways
or other figures of metal whilst cold may be split or separated and rolled or
formed into other rails rods, plates or figures or sections of iron or metal for use
as desired..
The plates bars or other forms especially rails of metal to be transformed are
whilst cold run between one or more pairs of cutting discs, operating under suitable
pressure so that one disc of each pair acts on each opposite face of the form of
metal. These discs are made with cutting or knife edges and where a series of
them are caused successively to operate on the same piece of metal, each succeeding
pair are arranged in closer proximity to each other than the preceding pair, and
each pair of cutting discs are made of successively thinner section or more acute
angle of cutting surfaces. The metal is partially cut by the first pair of discs,
further cut by the next pair and so on until the operation of partial severance is
successfully accomplished to fit it for the succeeding operating which consists in
passing these partially severed pieces between one or more pairs or series of rollers
by which means the complete separation is effectuated.
The divisions of the original piece of iron rail or other form of metal are then'
heated to the necessary heat and are separately run through rollers for development
into the further forms required.

at a point just below the head and again just above the flange will give three
forms of rod or bar-one the mid-rib may be rolled out simply whilst the other
two may be further developed into forms more or less nearly approximating thus
the head may be developed a V, a T, or other section and likewise so may the
Hange piece. Or, one toe of the whole rail cut off, it may be by these means
transformed into a trough or allied form of channelled iron with great economy,
utilizing the original sectional form of the rail or figure of the metal as a base for
progressive development into the required shape or figure of flat, channel angle, or
other sectional form of metal desired, aided by the division or separation of parts,
as set forth.

I LOUIS MANNSTAEDT of Kalk near Cologne in the German Empire Director
of the Humboldt Rolling Mills at that place do hereby declare the nature of
my invention for IMPROVEMENTS IN THE FORMING OF. METAL RODS, PLATES OR
OTHER SHAPES FROM RAILS OR OTHER FORMS OF METAL AND IN APPARATUS
THEREFOR, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of the invention is to enable the rails produced for railway use and
other forms of metal to be utilized for other purposes, by cutting and rolling or
forming such rails or forms of metal whilst in a cold state into rods, plates strips
or other desired shapes for reuse and in apparatus therefor.
By these means forms existent of metal such particularly as rails for railways
or other figures of metal whilst cold may be split or separated and rolled or
formed into other rails rods, plates or figures or sections of iron or metal for use
as desired.
The plates barsi or other forms especially rails of metal to be transformed are
whilst cold run between one or more pairs of cutting discs, operating under suitable
pressure so that one disc of each pair acts on each opposite face of the form of
metal. These discs are made with cutting or knife edges and where a series of
them are caused successively to operate on the same piece of metal, each succeeding
pair are arranged in closer proximity to each other than the preceding pair, and
each pair of cutting discs are made of successively thinner section or more acute
angle of cutting surfaces. The metal is partially cut by the first pair of discs,
further cut by the next pair and so on until the operation of partial severance is
successfully accomplished to fit it for the succeeding. operating which consists in
passing these partially severed pieces between one or more pairs or series of rollers
by which means the complete separation is effectuated.
The divisions of the original piece of iron rail or other form of metal are then.
heated to the necessary heat and are separately run through rollers for development
into the further forms required.
Thus in the case of a railway rail with head, mid-rib and bottom flange severance
at a point just below the head and again just above the flange will give three
forms of rod or bar-one the mid-rib may be rolled out simply whilst the other,
two may be further developed into forms more or less nearly approximating thus
the head may be developed a V, a T, or, other section and likewise so may the
flange piece. Or, one toe of the whole rail cut off, it may be by these means
transformed into a trough or allied form of channelled iron with great economy,
utilizing the original sectional form of the rail or figure: of the metal as a base for
progressive development into the required shape or figure of flat, channel angle or
other sectional forn of metal desired, aided by the division ori separation ofiparts,
as set forth.

through a cog mill with flat and vertical
grooves (such as fig. 19) or with pointed grooves (as in fig. 20) and rolled to an
approximate square section, into billets. These billets are afterwards rolled out
into the section required.
b. The rails are rolled when warm flat and treated like blooms.
c. The rails are cut warm into strips, which again are piled as described under
paragraph a.
If the heads should consist of fine grade iron they are rolled into billets and
afterwards used up for wire rods.
d. The rails are in their original section reduced by alternately rolling the same
flat and an edge until the sections are reduced for such light rails as used chiefly.
in the mining districts.
According to my invention my object is to do away with the whole process of
piling, rolling out of the bloons to rods, bars etcetera as is the present custom and
to utilize the approximate forms already possessed by the rails to and therefrom to
develop the approximate sections to be rolled out.
According to my method I am able to produce.
1st Tee iron, the strips a, b, c, d, having already a tee shape or e, f, g, h, (see
figures 13, 14, 15, 16) I roll the strips directly into tee sections by causing them
to be passed a few times through the rolls (such as figures 21, 22).
2nd Angle iron, the strips b, d, g, figures 14, 16, have in two surfaces approxi-
mate angle form (figure 23) and consequently are rolled direct into angle iron
(figures 24, 25).
3rd Flat bar and hoop Iron strips e (figure 16) have a complete flat iron section.
Strips d (figure 16) with flat footed rails have approximate flat iron section.
Both are rolled direct into flat iron or hoop iron (figure 26).
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
1. The cold splitting or dividing of rails of iron or steel by rolling grooves
therein and causing the severance of the same into parts by means of suitably
formed shearing or severing parts such parts so severed approximating as nearly as
may be to the forms to be developed and the rolling or forming of such strips or
parts so separated into strips or pieces of metal of sections approximating to the
original divisions of the rail strips substantially as set forth.
2. The construction or arrangement of the mechanism as shewn and described
for the said purpose.
