PROVISIONAL SPECIFICATION.
An Improved Method of Rolling Wheels, Discs, and other Bodies or
Articles.
I, JOSEF KLEINPETER, of Leobersdorf near Vienna, in the Empire of Austria,
Manager, do hereby declare the nature of this invention to be as follows:-
The present invention relates to an improved method of manufacturing wheels,
discs and other bodies or articles by radially rolling the material or ingot used for
such bodies in such manner that the ingot rotates on its own axis while undergoing
the rolling process.
A pair or pairs of rollers of conical or nearly conical form, mounted at an angle
of inclination to each other and having corresponding profiles, are employed for
carrying out this rolling process.
The ingot to be rolled is placed in the mill in a cold-warm or red-hot state
according to the nature of the material, and, by the gradual bringing together or
approaching of the rollers and diminishing their angle of inclination, the required
form or finish of the body or article is secured.
The rollers employed in the process are of conical or nearly conical form, being
correspondingly profiled in such way, that their longitudinal section corresponds to
the radial profile of the disc or wheel etc., to be produced, so that, by the
said rollers bearing radially upon the ingot, the latter ultimately receives its
desired form.
Several pairs of such rollers can be arranged if required, sufficient room being
left for the ingot to be introduced into the mill from the side.
In manufacturing certain bodies or objects, as, for instance, railway-wheels etc. a
rapid and correct distribution of the material is of the utmost importance. This
is effected according to this invention by causing the end or point of one or both
of the conical rollers to engage the ingot at or near the centre and then, the said
point or points being not only brought together or caused to approach each other,
but also by the angle of inclination of the rollers forward by their axis, being
gradually reduced, so that the ingot is pressed out to the periphery, the definite or
finished form of the wheel, disc or other body is obtained.

COMPLETE SPECIFICATION.
An Improved Method of Rolling Wheels, Discs, and other Bodies or
Articles.
I, JOSEF KLEINPETER, of Loebersdorf, near Vienna, in the Empire of Austria,
Factory Manager, 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 :-
The objects of my invention are to manufacture wheels, discs, or other articles
from ingots by radially rolling same, whereby the ingot is caused to rotate on its
own axis, during the rolling process.

page_text: A pair or pairs of rollers of conical or approximately conical form mounted at
an angle inclined to each other and having corresponding profiles, are employed
for carrying out this rolling process, as diagrammatically shewn in Fig. 1 of the
accompanying drawings.
The ingot to be rolled is placed in the mill in a cold, warm, or red-hot state
according to the nature of the material to be treated; as the operation advances,
the ingot receives its finished form, by the rollers of a co-operating pair gradually
approaching each other, and by the reduction of the angle of inclination of such
co-operating pair of rollers.
The rollers bb (Fig. 8, which is a sectional view of a device for carrying out
the method), are of somewhat conical form, and profiled in such way that their
longitudinal section corresponds to the radial profile of the disc or article to be
obtained, so that by said rollers engaging with or bearing against the ingot radially,
the latter ultimately receives its desired form.
Several pairs of rollers can be arranged if required; Fig. 2, for instance, of the
drawing shows, in plan view, diagram of the arrangement of three pairs, which, as
shewn at f, leave sufficient room for the introduction of the ingot into the mill from
the side.
In manufacturing certain bodies or articles, as for instance, railway wheel discs
or similar bodies, a rapid and correct distribution of the material is of the utmost
importance.
This is effected, as shewn in Fig. 3, by causing the end or point c of one or both
conical rollers to engage the ingot in or near the centre, and then by said point or
points, being not only brought together i.e. by an inward movement imparted to
same, but also by the angles of inclination a ẞy etc., (Fig. 3 to 7) formed by the
axes, xy, being gradually reduced until the ingot is pressed out to the periphery
as shewn in progressive stages in Figs. 4, 5 & 6, so that all parts of the roller
surfaces successively take part in the rolling action until the final or complete form
of wheel, disc, or other article is obtained, as represented in Fig. 7, which is a
sectional view of the arrangement.
Seeing that various constructive arrangements for carrying out the improved
method may be employed, the method alone as herein described, is claimed & sought
to be protected.
In order however, that the operation may be properly understood, Figs. 8-11,
which are sectional elevation, plan & detail views respectively, will serve as
examples of an arrangement of rollers for carrying out my method.
The bearing h, of the axis of the lower roller 6', is mounted on a strong frame
or support g (Figs. 8 & 9) said rollers being driven by bevel wheels i. j. through
the gearing l. k.
The shafts of upper rollers b, b, are mounted in bearings or supports m, which
can be reciprocated in frames n, pivotally arranged on bolts n¹ in the frame i, at
the lower end, and on bolts o¹, in the fork-like frame o, at the upper end.
By means of bolts o², the arms or forks o, are connected with a threaded sleeve p,
on spindle q, which is mounted in a bearing and can be revolved, so that by
revolving the spindle, the sleeve p. is raised or lowered.
It will now be evident that both the frames n, and the shafts b, adjustable in
said frames by means of hand wheels, and spindle t, can be adjusted to different
angles (a) as required for carrying out this improved method of rolling.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner same is performed, I declare that what I claim is :-
Improved method of radially rolling wheel discs, or other articles, substantially
by means of conical rollers, the shafts of which are inclined to each other, and
adjustable as to the angle of inclination, such rollers first operating on the ingot
introduced between them, with their points or ends near to the centre of the article
to be rolled, and, as the operation proceeds, by reducing the angle of inclination of
the roller shafts, pressing the material of the ingot from the centre to the periphery,

the drawings.
