PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Railway Carriage and like
Wheels.
I, THOMAS WILLIAM MOSELEY JACKS, of Park Villas, Wood Green,
Wednesbury, Engineer and Manager of Works, do hereby declare the nature of
this invention to be as follows:-
My invention relates to the manufacture of iron or steel wheels for railway
carriage or like purposes, as I shall describe referring to the accompanying
drawings shewing my method of manufacturing a rimmed wheel.
Figs. 1 and 2 shew the form of blank to be operated on by a pair of rolls and
Fig. 3 shews it in position to be rolled.
I first forge in iron or steel or cast in steel a blank B which is of less diameter
than the finished wheel and tapers to a greater thickness from near the boss to the
rim. It may also be made with a shallow rim as shewn in Fig. 1. I mount this
blank on a centre stud C projecting from a slide D, and I bring it within the grip
of a pair of rollers R R¹. As the rollers are made to approach each other, the
web and rim are formed to the shape indicated by the dotted line, the centre C
receding as the web is reduced in thickness and the diameter of the wheel increases
the tread T bearing against a collar E on one of the rolls which can enter a
groove F in the other roll.
When a plain disc without rim is to constitute the central part of a wood block
wheel, the rollers do not require a collar or groove. And when wheels of other
forms are to be made, the blanks and rolls are shaped accordingly. Instead of a
wide roller such as R or R' made in one piece, I sometimes employ a narrow roll
fixed on its shaft and beyond it another roll or a pair of rolls loose on the shaft, so
that they can accommodate themselves to the speed of the part of the wheel on
which they bear. When a considerable surface of the blank has to be acted on
I may employ conical rolls fixed on axes inclined to the axis of the wheel and to
each other.

Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The herein described manufacture of railway carriage and like wheels by first
forging or casting a blank of less diameter than the finished wheel, mounting the
blank by a central hole on a stud projecting vertically from a horizontal slide aud
subjecting the blank, while it revolves on the stud, to the action of a pair of
horizontal rollers between which the blank is gripped.
