page_text: Improvements in and relating to Pneumatic or Elastic Ball
Tyres for Cycles, Motor Cars, and other Road Vehicles.
I, CLARA COLLS of Beaconwood Barnt Green in the County of Worcester do hereby
declare the nature of this invention to be as follows:-
This invention relates to an arrangement of pneumatic or elastic Ball Tyre whereby
in the event of puncture or for other purposes it becomes a very easy matter to detach
the punctured section or ball from therein and insert a fresh one thus repairing the tyre
expeditiously and effectually.
To effect my purpose a series of india rubber hollow balls form the tyre the rim of
may be of any suitable construction that will answer the requirements.
Said balls each have a square shaped flat flange or collar of solid rubber integral
with and located near to the base or crown of same, which flange or collar exceeds the
diameter of the ball and overhangs upon the sides that are inserted beneath
circunferential flanged edges of the rim (or other suitable construction of rim) upon
each side thereof so that said rubber flanges are passed into position and obtain a firm
bearing therein the base of each ball lying within the concave or other form of
rim.
In cross section the lateral edges of the square flanges of each ball touch when
inserted in the rim as described so that whilst they are each held firmly in position
the fact of their being in immediate contact each to each is an additional means of
strength and support to the whole series comprising a continuous tyre of balls or
similar sections. Each ball as soon as placed in the rim is perfectly firm and
independent of its neighbour except for the purpose of combined support.
The advantage of my arrangement is that the solid flange or collar being of a square
formation it is obviously impossible for any individual ball or section to work round
or become displaced from the rim in wear which not infrequently is the case with
other kinds of ball tyres.
Whilst each ball is securely attached in manner stated any one of them can be
readily detached as will be seen,
The tyre being thus composed in sections many advantages exist for the purposes
of repairing renewing and otherwise, whilst preserving the essential features of a
pneumatic or elastic tyre.
The balls or sections may if desired be covered with a casing or casings of leather
or other suitable material attached in any suitable manner either to the balls or to
the rims.

Tyres for Cycles, Motor Cars, and other Road Vehicles.
I, CLARA COLLS of Beaconwood, Barnt Green in the County of Worcester, 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 reference being had to the drawings accompanying this specification and
to the figures and letters shewn thereon:-
My present invention relates to an arrangement in connection with Pneumatic or
Elastic Ball Tyres for attaching and securing the balls or sections in the wheel rims
and whereby in the event of puncture or for other purposes it becomes a very
easy matter to detach the punctured ball or section and to insert a fresh one, thus
repairing the tyre expeditiously and effectually, furthermore in the event of a
puncture the rider can proceed without removing the damaged ball or section.
Figure 1 represents a part side elevation of a rim and ball tyre.
Figure 2 represents a plan of same.
Figure 3 represents a cross section of a rim shewing the arrangement of flanged
ball in position.
Figures 4 & 5 are views of the ball separately.
Figure 6 a section. Figure 7 represents the flanged ball in plan.
To effect my purpose a series of India Rubber or Elastic Hollow Balls or sections A
form the Tyre the wheel rim B of which may be of any suitable construction that will
answer the requirements having flanged or other suitable edges or of the skeleton
form described and illustrated in the previous Specification of Patent No. 10773
of 1896. Each ball A is formed with a square or nearly square solid flange A¹, which
is made integral with same and situated preferably near to the base (or other
convenient positions thereon).
It will be seen on referring to the drawings that the mode of attaching the balls A
as shewn consists in passing the square or nearly square solid flanges A¹ beneath the
flanged or inturned circumferential edges B¹ of the rin B. said balls A obtaining
their seating within the rim and being retained rigidly in position by the solid
flanges A' by means of which they obtain a firm bearing. In cross section of the
rim B the meeting edges of the square flanges A¹ of each ball preferably touch when
inserted in the riin as described so that whilst they are each held firmly in position
laterally in the rim the fact of their being in immediate contact each to each is an
additional means of strength and support to the whole series.
The object and advantage of my arrangement as herein described is that the solid
flanges or collars being of a square or nearly square shape it is obviously impossible
for any individual ball or section to work round or become displaced from the rim in
wear, at the same time a ball can be readily detached when required as will be
understood.
The Tyre being thus composed in sections many advantages exist for purposes
of repairing, renewing and otherwise, whilst preserving the essential features of
resiliency of a pneumatic or Elastic Tyre.
The solid Flanges situated on the balls as shewn the greater part of said balls is
available for the tread of the Tyre thus affording increased resiliency.
Having now particularly described and ascertained the object and nature of my said
invention and in what imanner the same is to be performed I declare that
what I claim is,
Firstly. In combination with Pneutnatic or Elastic Ball Tyres or Treads of similar
sections for the wheels of cycles, Motor cars Velocipedes and other Vehicles the

page_text: special construction and arrangement of a series of hollow balls or sections having
solid rubber square or nearly square flanges or collars formed integral therewith said
rubber flanges engaging the flanged or other suitable edges of the wheel rims or the
rims of skeleton formation herein referred to and retained and fixed therein
substantially as described.
Secondly. In wheel rims the balls and special form of flanges or collars thereon
situated near to the base or crown of same preferably or other convenient position
adapted to engage said rims and in combination therewith in manner described.
Thirdly. Forming square or nearly square solid rubber flanges upon the balls or
sections, said flanges being situated near to the base or crown of same substantially
as described.
