PROVISIONAL SPECIFICATION.
Improvements in Machinery for Rolling Flanged Tires for Railway
Wheels.
We, WILLIAM BEARDMORE, of Parkhead Forge, Parkhead, in the County of
Glasgow, North Britain, Steel Manufacturer and Forge Master, and WILLIAM
COPE, of the same place, Tire Mill Roller, do hereby declare the nature of this
invention to be as follows, that is to say:―
This invention has for its object to improve the construction and action of
machinery for rolling flanged tires for railway wheels, and so that the tires may
be rolled to a finished condition with one heating of the annular bloom or ring
operated on.
In the improved machinery a roll shaped for acting on the circumference
and parts of the flat faces of the ring is fixed on a driven rotating shaft, and a
small roll shaped for acting on the inside of the ring and the remainder of the
flat faces is placed loosely on a non-rotating shaft which is moved towards the
other shaft as the radial dimension of the tire becomes reduced by the rolling
action. The small roll has its flanges which correspond to parts of the flat faces
of the ring made with a slight bevil so as to cut of any small portion of metal
which may exude during the rolling action, the cutting off being effected by the
said flanges ultimately coming into contact with the Hanges of the larger roll.
Brass bearing rings are fitted to the small roll, one between the roll and a collar
on its shaft, and the other between the other side of the roll and a collar or cover
fixed on the shaft by means of a screw nut. A recess to contain a lubricant is
formed between the collar or cover and the roll.

Improvements in Machinery for Rolling Flanged Tires for Railway
Wheels.
We, WILLIAM BEARDMORE, of Parkhead Forge, Parkhead, in the County of
Glasgow, North Britain, Steel Manufacturer and Forge Master, and WILLIAM
COPE, of the same place, Tire Mill Roller, 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, that is to say: -
This invention has for its object to improve the construction and action of

page_text: machinery for rolling flanged tires for railway wheels, and so that the tires may
be rolled to a finished condition in one mill with one heating of the annular
bloom-or-ring operated on:
And in order that the said invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing a part of a rolling mill sufficient to
illustrate the improvements.
In the improved machinery a roll, A, shaped for acting on the circumference, B,
and parts of the fat faces, C, of the bloom or ring, D), is fixed on a driven rotating
shaft, E; and a small roll, F, shaped for acting on the inside, G, of the ring, D,
and the remainders of the flat faces, C, is placed loosely on a non-rotating shaft, H,
which is moved towards the other shaft, É, as the radial dimension of the tire, D,
becomes reduced by the rolling action. The faces of the flanges, J, K, L, M, of
the rolls, A, F, are preferably made with a small amount of taper as shown at, N.
The small roll, F, has the circumferences of its flanges, L, M, which correspond
to parts of the flat faces, C, of the ring, 1), made with a slight bevil as shown
at, P, so as to cut of any small portion of metal which may exude during the
rolling action, the cutting off being effected by the said flanges, L, M, ultimately
coming into contact with the flanges, J, K, of the larger roll, A. It may be of
advantage for the same purpose to shape the flanges, J, K, with a similar circum-
ferential bevil as shown at, Q, or these flanges may be made without this bevil.
Brass bearing rings are fitted to the small roll, F, one, R, between the roll and a
.collar, S, on its shaft, H, and the other, T, between the other side of the roll and
a collar or cover, V, fixed on the shaft by means of a screw nut, V. A brass
bearing piece, W, is also fitted in a recess in the shaft, H, on the side taking the
bearing strain.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
In machinery for rolling flanged tires for railway wheels, the combination of
an external roll fixed on a driven rotating shaft with a smaller internal roll
placed loosely on an adjustable non-rotating shaft, the rolls being shaped and
acting on the bloom or ring substantially as hereinbefore described and as shown
on the accompanying drawings.
