Improvements in Railway and other Wheels.
WILLIAM TOZER of 95 Finsbury Pavement London Merchant FREDERIC
BARRY STANTON of 11 Queen Victoria Street London Engineer do hereby declare
the nature of this invention to be as follows:-
Our invention is as follows-
Our invention relates more particularly to disc wheels for railway and other
purposes and especially as to the mode of securing or attaching the discs to the
boss or nave. In the manufacture of these wheels, two or more discs may be used
and the naves may be of cast or wrought iron or steel or other suitable material
and the discs may be corrugated or may be plain of any suitable form.
We now proceed to describe our mode of forming the boss or nave so as to unite
it to the discs. After preparing the discs and before placing them together we
insert between them a ring or lining made of moulders sand, clay, cement fire clay
whether fired or not, or any suitable material the object of this ring or lining
being to prevent the metal forming the boss from spreading into the space between
the discs during manufacture. We then proceed to cast or forge the boss around
and between the discs in the usual manner by means of the usual plant and
appliances or any other more suitable means.
After the wheel centre is made the ring or lining which prevented the hot metal
from spreading between the discs, can be removed by means of proper tools for
scraping it out or breaking it up or as the case may require. In the case of
wheels having forged bosses we prefer to make the discs with a recess, rib, or
groove or other equivalent device and to have a corresponding recess, rib or
groove on the ring or lining engaging therewith in order to assist in resisting the
pressure to which it is subjected while the boss is being forged out and around the
discs. In another modification we make the ring or lining of several pieces or
segments that can be fitted together between the discs or held together by means
of wedges or bands or other means, the said segments taking the place of the
complete ring or lining (or otherwise) described in previous paragraph and after
the boss is formed upon the discs, the segments can be released by slackening the
wedges or bands and removed from between the discs leaving the boss perfect and
complete.

Improvements in Railway and other Wheels.
WILLIAM TOZER, of 95 Finsbury Pavement, London, Merchant, and FREDERIC
BARRY STANTON, of 11 Queen Victoria Street, London, 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 disc wheels for railway and other
purposes, and especially as to the mode of securing or attaching the discs to the

page_text: boss or nave.
In the manufacture of these wheels, two or more discs may be used,
and the naves may be of cast or wrought irou, or steel, or other suitable material,
and the discs may be corrugated or may be plain, of any suitable form.
We now proceed to describe our mode of forming the boss or nave, so as to unite
it to the discs. After preparing the discs and before placing them together we
insert between them a ring or lining made of moulders sand, clay, cement, fire-clay,
whether fired or not, or any suitable material, the object of this ring or lining
being to prevent the metal forming the boss from spreading into the space between
the discs during manufacture. We then proceed to cast or forge the boss around
and between the discs in the usual manner, by means of the usual plant and
appliances, or any other more suitable means.
After the wheel centre is made, the ring or lining which prevented the hot metal
from spreading between the discs, can be removed by means of proper tools for
scraping it out or breaking it up, or as the case may require. In the case of
wheels having forged bosses we prefer to make the discs, with a recess, rib, or
groove, or other equivalent device, and to have a corresponding recess, rib or
groove, on the ring or lining engaging therewith in order to assist in resisting the
pressure to which it is subjected while the boss is being forged onto and around
the discs.
In another modification we make the ring or lining of several pieces or segments
that can be fitted together between the discs or held together by means of wedges
or bands or other means, the said segments taking the place of the complete ring
or lining (or otherwise) described in previous paragraph and after the boss is
formed upon the discs, the segments can be released by slackening the wedges
or bands, and removed from between the discs, leaving the boss perfect and
complete.
We will describe the manufacture of one of these wheels with reference to the
accompanying drawing.
Figure 1 is a section through a corrugated disc wheel.
Figure 2 is an elevation of a plain disc wheel.
Figure 3 is a section through a plain disc wheel.
A are the discs which may either be plain or corrugated.
B are the bosses which may be either wrot iron, cast iron or steel or other
suitable metal.
Care the lining rings which may be made either in one piece as shown, or may
be in segments, the said segments may be held together while the boss is being
formed by bands or wedges or either suitable means.
D is the space between the discs which in the case of wheels having cast bosses
may be filled in with moulders sand, when the boss is being cast upon, around, and
within the discs.
We will now procecil to describe the mode of forming the nave or boss B, so as
to unite it to the discs A.
In the case of wheels having cast bosses we fill or line the whole of the space D
between the discs with moulders sand leaving only such space between them as is
required for the boss itself, or instead of filling the whole space D with moulders
sand we insert between the discs the ring or lining piece C. which acts in the same
manner as the moulders sand and keeps the discs at the proper distance apart from
one another, and prevents the metal forming the boss or nave from flowing
while it is being cast beyond the confines of the said filling or lining.
In the case of wheels having forged bosses we do not employ moulders sand but
we employ the ring or lining piece C exclusively for the same purpose as described
above, this ring being made of clay, cement, fireclay, or any other suitable material
either in one piece or in segments, and if in segments the said segments may be
strengthened or reinforced so as to resist the pressure of the metal while the boss
is being forged, by wedges, bands or other suitable appliances, and in order further
to resist this pressure and to contribute to hold the ring or lining piece in place,
the discs A, may be ribbed or recessed at E. where they meet the ring or

page_text: lining piece C, and the ring or lining piece will have a corresponding rib or
recess to engage therewith.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
In a railway or tramway wheel made of two or more discs of metal united to a
boss or nave, whether of wrought or cast material, the means of uniting them
together by using a lining or ring of moulders sand, fireclay, cement, or other
suitable material or of segments or pieces shaped in the form of a ring and
suitably held together for accomplishing the same purpose, substantially as set
forth.
