PROVISIONAL SPECIFICATION.
Improvements in the Rolls of Rolling Machinery.
I, ALFRED BLACKWELL, of 264, Icknield Street, in the City of Birmingham,
Cycle Manufacturer, do hereby declare the nature of this invention to be as
follows:
―
This invention relates to improvements in, or additions to, the rolls of rolling
machinery, known in commerce as forge or mill rolls and consists in providing the
said rolls, which are of cast metal, with steel or wrought metal cores.
Cast metal rolls, as ordinarily constructed, break either transversely through
their middles, or at the junctions of their necks with the body parts.
It is understood that in such cast rolls, that the necks are cast integral with the
bodies, and that the surfaces of the bodies are usually chilled.
The object of my invention is to prevent breakage in or of the said rolls, by
having cast within their middles, a wrought steel cylinder, shaft or core, whose
ends extend beyond the ends of the body of the roll, and form the necks or bearings,
which take and work within usual holsters or housings.
In carrying out the production of a mill roll according to my invention, I take
a bar, core or central support of steel, hexagonal in cross section, and of the
desired girth, and I cast around the middle of the said bar or core, a cast metal:
body part, within a mould suitably arranged to chill the surface of the same. The
ends of the said core extending beyond the body of the roll are then cylindrically
turned, forming the necks. The steel or wrought iron central support or core is
preferably gapped or cut away for a short distance, so that the cast jacket shall be
prevented from shifting upon the steel core in an axial direction.
The wrought metal core or end-to-end bearing of the roll may be made cruciform
in cross section, round and flatted upon one or more sides, or the same may be;
elliptical, or of any figure whereby the jacket is prevented from turning upon the
wrought metal middle part.
The rolls may be chilled or unchilled upon their surfaces, according to the
cbaracter of the work for which they are to be employed. Thus in planishing
and sheet iron rolling, the same would be chilled, but for ordinary cogging down,
the same may be left soft.
I propose that the rolls should be cast with the wrought metal middle part
presented vertical, and that the metal in casting should be run in from the
bottom.
Dated this 8th day of March 1893.

Improvements in the Rolls of Rolling Machinery.
I, ALFRED BLACKWELL, of 264, Icknield Street, in the City of Birmingham,
Cycle Manufacturer, 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 improvements in, or additions to, the rolls of rolling

page_text: machinery, known in commerce as forge or mill rolls, and consists in providing the
said rolls, which are of cast metal with steel or wrought metal cores.
Cast metal rolls as ordinarily constructed, break either transversely through
their middles, or at the junctions of their necks with the body parts.
It is understood that in such cast rolls, that the necks are cast integral with
the bodies, and that the surfaces of the bodies are usually chilled.
The object of my invention is to prevent breakage in or of the said rolls, by
having cast within their middles, a wrought steel cylinder, shaft or core, whose
ends extend beyond the ends of the body of the roll, and form the necks or bearings,
which take and work within usual holsters or housings.

a bar, core or central support of steel, hexagonal in cross section, and of the desired
girth, and I cast around the middle of the said bar or core, a cast metal body part,
within a mould suitably arranged to chill the surface of the same. The ends of
the said core extending beyond the body of the roll, are then cylindrically turned,
forming the necks. The steel or wrought iron central support or core is preferably

in cross section, round and flatted upon one or more sides, or the same may be
elliptical, or of any figure whereby the jacket is prevented from turning upon the
wrought metal middle part.
The rolls may be chilled or unchilled upon their surfaces, according to the
character of the work for which they are to be employed. Thus in planishing
and sheet iron rolling, the same would be chilled, but for ordinary cogging down,
the same may be left soft.
I propose that the rolls should be cast with the wrought metal middle part
presented vertical and that the metal in casting should be run in from the
bottom.
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
Making the rolls of rolling machinery with a steel or wrought metal core,
cylinder or shaft as set forth.
