Improvements in the Manufacture and Construction of Metal Rolls.
I, STEFAN KOSSANYI, of 93, Külső Váczi-ut, Budapest, Factory Official, 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:-
My invention relates to rolls constructed in more than one piece which are
suitable for various industries and especially for rolling mills for the manufacture
of any plain or ornamental section of rolled iron.
The roll consists of a strong shaft A with necks a and coupling ends 6 Figs. 1, 2, 3, 4,
which in cross section may be elliptical, polygonal, triangular with rounded
corners or round provided with one or more flats or one or more grooves or other
suitable section whereby the rings c, Figs. 5, 6 and 7, which are provided with
a bore corresponding in section to that of the shaft A when threaded thereon to
form the body of the roll may be held fast thereon or wedged or keyed on so that
they revolve with the shaft.
The rings c in any desired number may be of various or of varying diameters
and the rolling surface may be grooved, scrolled, plain or ornamented with various
designs, so that the form of the usual groove or pass whether plain or ornamented
may be altered at will by the rearrangement of the rings. In order to prevent
the rings c from slipping off the shaft I provide a keep ring f Figs. 4 and 10
combined with a cylindrical sleeve f¹ having a bore corresponding in section to
that of the neck a, over which it is passed to form the journal.
k
To retain the sleeve fl in place I provide a ring u which is secured in a groove
in the coupling end b Fig. 1, 23 and 4. This ring n may be in halves and bolted
together as shewn in Fig. 9 or it may be provided with a single hinge joint, see
Fig. 11, or it may be composed of several links hinged together as shewn in Fig. 12.
Lastly a coupling sleeve l, Fig. 8 is provided having a bore corresponding in
section to that of the coupling ends b.
The sleeve while being cast is provided with a helical wire core m or with
rods o arranged concentrically around the axis.
The shaft A Figs. 1, 2, 3, 4, is cast in steel, nickel steel, iron or similar materials,
and in order that it may withstand greater pressure it is provided with a core
of wrought iron or steel tube, or H or channel iron q or other suitable section. This
core may be cast in or may be pressed in, while the casting is still hot, by hydraulic
pressure.
I provide the shaft A Figs. 1, and 3, at one end of the part corresponding to
the body of the roll with a fixed collar p to prevent the rings c from slipping off,
in which case the neck a adjoining the collar is cylindrical in cross section to
form the journal. I may however place the collar p near the centre of the
body (Fig. 2) in which case both necks a are similar in section and are each pro-
vided with a groove ka ring and sleeve f, f, and a keep ring n.
The rings c may be of steel nickel steel or similar metals and may be cast
rolled or pressed.
The shaft and rings c after being cast or rolled and while still glowing are

page_text: placed in a suitable divided iron or other metal mould and compressed therein
under a hydraulic or other press or subjected to the pressure of a dead weight
if they are to have a greater toughness and solidity.
I employ this process with all rolls that are to have an ornamented rolling
surface.

By means of this process the ornamentation or outline of the rolls or rings is
sharply defined.
с
or,
The rings & Fig. 5, when cast are provided with a spiral core of wire r
arranged concentrically around the axis, a series of rods & Figs. 6 and 7 or woven
wire to enable them to withstand a greater torsional strain.
In Fig. 5 is shewn an ornamented ring in one piece where a figured design is
required while Fig. 6 shews a series of roller designs consisting of a number of
rings of different or varying diameters.
In Fig. 6 a¹ care roller rings of varying diameter and 6¹ is a conical ring for
wedge shaped iron.
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. A roll with mutually interchangeable metal parts consisting of a strong
shaft A of elliptical, round with one or more flats or grooves, polygonal or other
suitable section provided with one or more interchangeable rings which may be
ornamented, of varying diameters, grooved or plain said shaft A being provided
at any suitable point with a fixed collar p to prevent the rings slipping off in one
direction and to prevent the rings slipping off in the other direction the said shaft
is further provided with a keep ring or rings f and sleeve or sleeves f¹ having
an elliptical or round cornered triangular bore and a hinged ring or rings u or
in place thereof a ring or rings in halves and bolted together in a groove or
grooves k in the neck or necks a.
2. In a roll according to Claim I a shaft A having a longitudinal central core of
wrought iron or steel I iron or tube either cast in or pressed in by hydraulic
pressure while still glowing and having a collar p inside the journal or at any
desirable point towards the middle.
3. Rolls or roller rings chaving an elliptical round cornered triangular or
other suitable bore for threading on the shaft A singly or in sets and having a
spiral wirer or rods s or woven wire cast in.
4. The method of obtaining in rolls or roll rings great solidity and toughness by
subjecting them while in a glowing state to hydraulic or other pressure.
5. The method of treating the working surfaces of rolls, or parts of rolls, for
forming different diameters, for ornamenting, providing grooves or ridges thereon,
by subjecting the rolls or parts of rolls while in a glowing state to hydraulic
or other pressure or to the pressure of dead weight in a mould.
6. Providing rolls of any construction with necks and coupling ends having
a round with one or more flats, round cornered triangular, polygonal or elliptical
section.
7. A keepring combined with a neck sleeve or either by itself and both having
a bore oval or polygonal with round corners in section.
8. Coupling sleeves having wire work cast therein concentrically with their
axes and having bores oval or polygonal with rounded corners in section.
