PROVISIONAL SPECIFICATION.
Improvements in the Construction and Manufacture of Wheels for
Road Vehicles.
I, CLAUDE CARTER of Holly Bank Levenshulme near Manchester in the County
of Lancaster Engineer do hereby declare the nature of this invention to be as
follows:-
In
My invention relates to that class of wheels which are used for carts, carriages
or other vehicles which travel on roads; and has for its object the strengthening of
the wheel so that it will more effectually sustain the ordinary wear and tear with less
damage and for a longer period than wheels constructed in the usual manner.
carrying my said invention into effect I construct the wheel in the following manner.
I cast of iron steel or other suitable material the nave or hub and the arms of the
wheel in one piece. I form the nave or hub of suitable strength and shape and
I may so design it as to permit of its being bushed with wood or some other
substance suitable for the purpose or I may construct it wholly of the material from
which it is cast. I construct the arms of a suitable section and I form at the end of
each arm a sole or shoe of suitable size and shape. To the soles thus formed I fasten
in any convenient manner the felloe which I make of wood in the ordinary way.
After the felloe is fixed and turned or otherwise trued up on its periphery I fix a
hoop or tyre by shrinking it on in the manner usually adopted. The tyre is afterwards.
secured in the same way as that pursued with ordinary wheels.

Improvements in the Construction and Manufacture of Wheels for
Road Vehicles.
I CLAUDE CARTER of Holly Bank late of Thursa Villas both in Levenshulme near
Manchester in the County of Lancaster 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 :-
My invention relates to that class of wheels which are used for carts carriages,
tramcars or other vehicles which travel on roads and has for its object the
strengthening of the wheel so that it will more effectually sustain the ordinary
wear and tear with less damage and for a longer period than wheels constructed in
the usual manner.
In order that my invention may be more easily understood I have hereunto
appended a sheet of drawings wherein Fig. 1 is a partial vertical section of the nave
and one arm of a wheel made according to this invention. Fig. 2 is a side elevation
of a portion of a wheel made according to this invention wherein the felloe F and
tyre G are shown in section and Fig. 3 is cross section through the arm C when
looking towards the felloe F. In all these drawings only so much of the wheel is
shown as is necessary to enable the method of construction of wheels made according
to this Invention to be clearly understood all the rest of the arms being made in a
similar manner.
I cast of steel iron or other suitable material the nave B and the arms C in one
piece. I form the nave B of the necessary strength and bore as to permit of it being
bored out to fit the axle A as shown in Fig. 1. Instead of forming the nave B as
there shown it may be made of sufficient size to allow of it being bored out to
permit it to be fitted with a bush with which the wheel would rotate in the manner
well understood. The bush may be made of iron or of any other suitable material
'
A

page_text: whether metallic or otherwise. The arms C as shown in the drawings are made
Hshaped in cross section but I do not bind myself to adopt this or any other section.
I may
make the arms elliptical round or any other convenient shape and they may
be either hollow or solid as preferred.
I cast on the end of each arm a sole or foot D on which the felloe F is bedded.
I also form a nipple or finger E which fits into a hole bored to suit it in the felloe F.
I form one of these nipples on the end of each arm and place it at such an angle
relatively to the radial line that the fingers E fitting into the same segment of the
felloe are parallel to each other. This enables the felloe segment to be easily fitted
into its place without straining the arms. After the felloe is attached to the arms in
the manner herein before described it may be turned on its periphery or otherwise
trued after which the wrought iron hoop or tyre G is shrunk on in the usual
manner. The shrinkage of the tyre G fastens all the segments of the felloe F
securely together and it is fixed to the felloe F in the manner usually adopted.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. The construction combination and arrangement of a wheel for road vehicles
consisting of a nave and arms cast in one piece, a felloe and tyre substantially as
herein described and illustrated.
2nd. In the construction of wheels for road vehicles the employment of a central
spider consisting of a nave and arms cast together and forming one piece substan-
tially as herein described and illustrated.
