do hereby declare the nature of this invention to be as follows:-
Our invention relates more particularly to what are known as disc wheels for
railways & tramways, and to improvements in their mode of manufacture, but it
may be applied to other articles such as pulleys.
We will describe our invention as applied to a railway disc wheel, composed of
two plates (preferably of iron or steel) united together at the boss or nave, and
having a tyre fastened upon the periphery or flanges of said plates.
In our previous Patent No. 14,722/1891 we have described how a wheel of this
character can be made by employing a ring or lining between the disc plates, the
said ring remaining between the plates after the wheel is made, but in order to
avoid loose pieces & to effect economy in manufacture we dispense with the said
ring or lining, & manufacture the wheel as follows:-
We take two plates or discs of suitable metal having holes at their centres and

made, we insert between the said plates two or more temporary segments, which when
assembled together would act in the same way as a ring or lining between the
discs & leave a space for the boss. The boss would now be formed upon & between
the plates by inserting a heated bloom or blooms through the centre holes in the
plates and forging them into the required shape in proper dies in a suitable
press.
The disc plates might either be heated to make a welded wheel centre or they
might be cold, & they might if thought desirable be pierced with holes near the
centre hole to enable some of the metal in the boss to pass through the holes while
it was being forged, & thus prevent the discs from turning in the boss after the
wheel is made. After the boss is made the segments as before described would be
withdrawn leaving the boss solid and homogeneous without any loose piece what-
ever & to enable the segments to be the more readily withdrawn the plates might
be made tapering as regards one another, that is to say being nearer to each other
at the boss than at their edges or peripheries.

or shrunk on said blocks & secured to the wheel centre in the usual manner.

BARRY STANTON, 11, Queen Victoria Street, London, E.C., Engineer, and HERBERT
BARRY TILFOURD STANTON, 20, Tivoli Road, Crouch End, London, N., Engineer,
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:
Our invention relates more particularly to what are known as disc wheels
for railways and tramways and to improvements in their mode of manufacture,
but it may be applied to other articles such as pulleys.
With reference to the drawings, Fig. 1 is a section through a wheel during
manufacture, Fig. 2, 3, 4, are sections through completed wheels.
We will describe our invention as applied to a railway disc wheel, composed of
two plates A, Fig. 1, (preferably of iron or steel) united together at the boss or
nave B, and having a tyre C, Fig. 2, 3, & 4, fastened upon the periphery or flanges
of said plates.
In our previous Patent No. 14,722/1891, we have described how a wheel of this
character can be made by employing a ring or lining between the
disc plates, A, the said ring remaining between the plates after the
wheel is made but in order to avoid loose pieces and to effect economy in manu-
facture we dispense with the said ring or lining and manufacture the wheel as
follows:-
We take two plates or discs A, of suitable metal having holes at their centres and
form them into shape in a hydraulic or other press. Before the boss or nave B is
made we insert between the said plates two or more temporary segments E, of
suitable construction and made of iron steel or other material, which when
assembled together would act in the same way as a ring or lining between the discs
and leave a space for the boss. The boss B, would now be formed upon and
between the plates by inserting a heated bloom or blooms through the centre holes
in the plates and forging them into the required shape in proper dies in a suitable

the centre hole to enable some of the metal in the boss to pass through the holes
while it was being forged; and thus prevent the discs from turning in the boss
after the wheel is made. After the boss is made the segments E as before
described would be withdrawn leaving the boss B solid and homogeneous without
any loose piece whatever and to enable the segments E to be more readily with-
drawn the plates A might be made tapering as regards one another, that is to say
being nearer to each other at the boss than at their edges or peripheries.
After the segments E are removed the plates or discs A would be brought
together at their peripheries as shewn in Fig. 2, and this could readily be done by
squeezing them in a suitable press and if necessary they could also be rivetted.
The squeezing of the plates together could be done either hot or cold.
It will be readily understood that the disc plates A themselves may be plain,
or corrugated, or dished, or of any suitable form, and that the wheel is completed
by securing a tyre C upon the periphery or flange of the plates or discs as shewn
in Figs. 2 3 & 4 in the usual well known methods.
It will be observed that while we have described that after the boss B is formed,
the plates or discs A are squeezed together so as to bring them close to one another
at their peripheries, this process might be left out, or distance pieces G Fig. 3 or
an annular ring might be inserted between them, and the plates then rivetted
together as described or they might be only partially squeezed together
without touching one another, and with or without the distance pieces
or annular ring being inserted and the plates rivetted up.
In a modification of this invention and in order to make wheels more applicable to
passenger carriages, after forming the boss upon the plates in the method described,
we insert blocks of wood H Fig. 4, or other suitable material between the plates A,
so as to reduce sound and give an easier running wheel, the tyre C being afterwards
forced or shrunk on said blocks and secured to the wheel centre in the usual
manner.
Having now particularly described and ascertained the nature of our inven-
tion and the way in which it is to be performed, we declare that what we
claim is:-
A wheel centre composed of discs or plates with a forged boss or nave made with
the aid of loose segments substantially as described and shewn on the accompanying
drawings.
