PROVISIONAL SPECIFICATION.
Improved Tyre and Rim for Cycle and other Wheels.
I, HENRY MOORE, of No. 21, Church Street, Whitehaven, in the County of
Cumberland, Tinman and Brazier, do hereby declare the nature of this invention
to be as follows:-
My invention consists in an improved tyre and rim for cycle and other wheels.
I refer to it as a tyre and rim because it is a combination thereof that I claim
to accomplish my object, and will describe them seperately starting first with the
rim say of a cycle. This I make of similar material to those at present in use
or any other suitable material, my rim is a lipped rim of a D shape, the lips may
be straight edged, curled, flanged, or bevilled but so made as not to cut the balls
from which I purpose using to construct or make up my tyre. The channel of my
rim may be coated with cement, enamelled, covered or lined with rubber, canvas
or other fabric. Secondly my tyre is made up and formed of a number of spherical
inflated rubber or other balls these I press into the channel of the rim all round
the wheel which thus forms my tyre, my rim being made to grip the sides of each
ball. The said balls are made with a concave dinge, dint or bulge in one side
only, this concave bulge or dint receives the convex part of its neighbouring ball
and thus forms an additional binder or grip longitudinally all round my tyre,
as a further protection and in order to prevent any part of my tyre from leaving
the rim I may have the balls made with a flange or ridge on each of their sides as
a further side holdfast after they the said balls have been pressed into position in
my rim. I entirely dispense with an inner or air tube and valves and the rider
of a machine fit with my invention need not carry a pump.

Improved Tyre and Rim for Cycle and other Wheels.
I, HENRY MOORE, of 21, Church Street, Whitehaven, in the County of
Cumberland, Tinman and Brazier, 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:-
This invention relates to improvements in that class of tyre comprising a
number of balls placed round the periphery of the rim and is designed to render
such tyre more compact than has hitherto been the case.
It consists essentially in constructing the ria of D shape with contracted or

page_text: lipped edges and the tyre of a number of inflated balls fitted into and gripped by
said rim each ball being formed with a concave dinge or dint in one side with
which the adjacent convex part of the neighbouring ball engages to form a lock
to assist in holding the ball in position.
It will be fully described with reference to the accompanying drawings.

Fig. 2. Transverse section through ball and rim (on line y Fig. 1).
Fig. 3. Perspective view of ball showing dinge or dint in side of ball.
The
The rim A is made of a deep D or channel shape the edges a being contracted
or lipped so that it is narrower across at the edges than nearer the bottom.
contracted lips or edges a may be straight, curved, curled, flanged, bevelled or
otherwise shaped.
The interior of the rim channel may be coated with enamel or cement or covered
with rubber or canvas or other material if desired.
i
The tyre is formed of a number of spherical inflated balls B of rubber or other
suitable material. Each of these balls is formed or moulded with one side b
indented inwards so that even after inflation the ball under slight external
pressure assumes that shape or formation.
The tyre is made up by a number of these balls fitted closely into the channel
shaped rim A and pressed tightly one against the other around the circumference
of the rim so that the spherical or convex part of one ball pressing against the next
causes it to assume the concave shape provided for by the dinge or dint formed
in the moulding and thus locking one ball into position by the adjoining one.
The balls are preferably corrugated, grooved or roughened on the periphery to
prevent side slip.
The balls may also be made if desired with a flange or ridge on each side to
engage with the edges of the rim to hold them more securely in position.
By this construction I am enabled to dispense with an inner or air tube and
inflating valves. Should a ball become cut or punctured the tyre can be readily
repaired by removing it and replacing it with another.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is:
1. A cycle tyre comprising a rim of D or channel shape with contracted edges
and a number of inflated balls inserted therein each ball formed with a dinge or
dint in one side to engage with the convex or spherical part of the adjoining ball
substantially as described.
2. A. cycle tyre having the several parts constructed and arranged in combination
substantially as described and shown in the drawings.
