IMPROVEMENTS IN WHEEL TYRES AND IN THE METHOD OF ATTACHING THE SAME TO THE WHEEL BODIES
Year: 1884

page_text: PROVISIONAL SPECIFICATION,
I SAMUEL RIDEAL of 9 Wards Buildings Deansgate Manchester in the County
of Lancaster, Civil Engineer do hereby declare the nature of the said invention
for "IMPROVEMENTS IN WHEEL TYRES AND IN THE METHOD OF ATTACHING THE
SAME TO THE WHEEL BODIES to be as follows :—
32
My Invention relates to the wheels adapted for use on Railways and Tramways
and has for its object to produce a strong and at the same time comparatively light
wheel having the tyre firmly attached. I make the body of the wheel of steel
cast in one piece and formed with a periphery to receive the tyre and with a hub,
web and strengthening ribs. The edges of the periphery are beveled or inclined
inwards in order that the tyre may obtain a firm bold. I also make the tyre of
steel cast to about the required working size with the requisite allowance for
turning and fitting. I prefer to cast both the wheel body and the tyre in rapidly
revolving metal moulds but I do not confine myself to this. The tyre is formed
on one side with an inwardly projecting lip which is beveled to fit one edge of
the periphery of the wheel body. The other side of the tyre is cast with fingers
or claws which project outwardly at intervals around the tyre. When the tyre is
forced or brought into position upon the wheel body these fingers or claws are
bent or clenched over and inwards by hammering or by hydraulic pressure or hy
suitable means so as to firmly grip the periphery of the wheel. I prefer to fork
the outer ends of these fingers or claws or to make them of a slotted form and to
arrange that when they are clenched or pressed home the forked or slotted part of
each shall engage with a rib upon the wheel body so that the tyre is prevented
from turning upon the wheel body or the fingers or claws may be arranged in
pairs or be so situated as that they shall bear against different sides of the ribs so
as to produce the same result.

DEVITRATION,
I, SAMUEL RIDEAL of 9 Wards Buildings Deansgate Manchester in the County
of Lancaster Civil Engineer do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN WHEEL TYRES AND IN THE METHOD OF ATTACHING THE
SAME TO THE WHEEL BODIES," and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement and
accompanying drawings:—
My Invention relates to the wheels adapted for use on Railways and Tramways
and has for it's object to produce a strong and at the same time comparatively light
wheel having the tyre firmly attached.
I make the body of the wheel of steel cast in one piece and formed with a 1
periphery to receive the tyre and with a hub, web and strengthening ribs.
The edges of the periphery are beveled or inclined inwards in order that the'
tyre may obtain a firm hold. I also make the tyre of steel cast to about the
required working size with the requisite allowance for turning and fitting. I prefer
to cast both the wheel body and the tyre in rapidly revolving metal moulds but
I do not confine myself to this. The tyre is formed on one side with an inwardly
projecting lip which is beveled to fit one edge of the periphery of the wheel
body. The other side of the tyre is cast with fingers which project outwardly at
intervals around the tyre. When the tyre is forced or brought into position upon
the wheel body these fingers are bent or clenched over and inwards by hammering
or by suitable means so as to firmly grip the periphery of the wheel. I prefer to
fork the outer ends of these fingers' or to make them of a slotted.form and to
arrange that when the fingers are clenched or pressed home the forked or slotted
part of each finger shall engage with a rib upon the wheel body so that the tyre is
prevented from 'turning upon the wheel body or the fingers may be arranged in
pairs or be so situated as that they shall bear against different sides of the ribs so
as to produce the same result.
'
In order that my Invention may be fully understood I will describe the same
with reference to the accompanying sheet of drawings.
In the said drawings Fig. 1 represents a front view and Fig 2 a vertical section
of a Railway or Tram car wheel constructed in accordance with my Invention.
In the said Figs. a is the tyre and b is the body of the wheel,
The tyre is by preference cast to the required form in a revolving mould but any
suitable means and process may be adopted. The tyre is cast with a lip or flange c
which projects inward from one side and with fingers & which project outwardly
from the other side of the tyre as indicated in Fig. 3. The wheel body is made
of steel oast in one piece as. herein before mentioned and one edge of the periphery b¹
is turned to a bevel the inner side of the lips c being beveled to correspond. In
the example, the fingers or claws, dare cast in pairs with a space between the two
fingers in each pair sufficiently wide to receive one of the spokes e of the wheel.
When the suitably turned or prepared tyre is forced upon the wheel body the lip o
is forced into close contact with the beveled side of the periphery b¹. The fingers

page_text: or claws & are then hammered over or are pressed inward toward the inner side of
the periphery of the wheel body so as to tightly clamp the part b. The tyre will
then be securely fixed in position upon the wheel body.
In the event of the tyre becoming loose through fracture it will be prevented
from turning upon the body by reason of the hold which the fingers or claws d,
have upon the periphery and also upon the spokes. In place of arranging the
fingers in pairs each finger may be comparatively wider than shewn and be formed
with a slot at the end to receive the web of the spoke or the fingers may be
arranged at suitable distances apart around the tyre without being adapted to lock
against the spokes or the fingers or some of them may be pressed into recesses in
the periphery of the wheel body so as to lock the tyre in position. I do not
confine myself to the number of fingers cast upon the tyre nor to the number of
spokes in the wheel body.
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. The combination of a cast steel wheel with a cast steel tyre formed and fixed
upon the wheel body substantially as and for the purposes set forth and indicated.
2. Casting the tyres for wheels of the railway or tramway class with fingers or
claws which can be hammered or pressed over the edge of the periphery of the
wheel body or into recesses formed therein so as in conjunction with beveled lips
or flanges to secure the tyre in position substantially as set forth and indicated.
3. A steel wheel tyre cast with pairs of fingers or with slotted tingers which can
be hammered or pressed over the edge of the periphery of the wheel body the space
between the fingers in cach pair or the slot in each finger when so hammered or
pressed over being occupied by a portion of the web of a spoke of the wheel
substantially as and for the purpose set forth and indicated.
