Improvements in and relating to Rims and Tyres of Wheels for
Cycles and other Vehicles.
I, GEORGE BECKETT BATTEN, of 2, Underhill Road, Lordship Lane, Dulwich,
London, S.E., Doctor of Medicine, do hereby declare the nature of this invention
to be as follows:-
A device whereby the tyres, felloes or rims of wheels, especially of cycles and
other vehicles, may be improved so that brakes and brake power may be applied
to them more advantageously, and also whereby less wear & tear be caused to the
said tyres, felloes or rims when the brake or brakes are applied to them. I propose
to secure these advantages by the addition to the tyres, felloes, or rims of a special
shoe or wearing surface upon which the surface of the brakes may impinge when
the brakes are applied. This wearing surface or surfaces may be of any suitable
shape, and situated on any suitable part or parts of the tyres felloes or rims, and
may be made of indiarubber canvas, wood steel or any suitable materials, and may
either be incorporated with the tyres felloes or rims as an essential part of them,
in the process of manufacture, or may be added to them afterwards in any suit-
able way. This improvement is especially intended for pneumatic tyres but may
be used for any tyres felloes or rims.
In carrying my invention into effect for example with reference to pneumatic
tyres, I may proceed as follows: In the manufacture of the rubber tyre I forin
preferably two projections one on each side of the tread, all round the length of
the tyre, such projections being shaped so as to act as a wearing surface against
which the brake may press.
Where this wearing surface is made of rubber, it
may be additionally vulcanised or otherwise hardened; or it may be composed of
other relatively hard or more wear resisting material, the object being to retain
the resiliency of the tyre while at the same time having a more resistant surface
upon which the brake can act. This devics in addition to its primary object of
providing wearing or resisting surfaces for brakes, may also, be useful in prevent-
ing side slipping.

page_text: and in what manner the same is to be performed to be particularly described and
ascertained in and by following statement:-
A device whereby the tyres felloes or rims of wheels especially of cycles, motor
cars and other vehicles may be improved so that brakes and brake power may
be applied to them more advantageously, and also whereby less wear and tear is
caused to the said tyres, felloes or rims when the brake or brakes are applied to
them. At present brakes of very many kinds are adapted to suit tyres, rims and
felloes, and I propose by my invention to adapt tyres, rims and felloes to suit
brakes and braking power.
I propose to secure these advantages by the addition to the tyres, felloes or rims
of a special wearing surface upon which the surface of the brakes may impinge
when the brakes are applied; this wearing surface or surfaces may be of any suit-
able shape and situated on any suitable part or parts of the tyres, felloes or rims
and may be made of indiarubber, canvas, leather, wood, steel or any other suitable
materials or combination of materials or composition suitable for the purpose.
This special surface or shoe would usually be all along the length of the tyre,
rim or felloe longitudinally. This special surface or shoe may be incorporated
with the tyres, felloes or rims as an essential part of them in the process of manu-
facture or may be added to 'them afterwards in any suitable way; it is not essential
to my invention that this special shoe or wear resisting surface should project
above the general surface of the tyre, felloe or rim, but only that it form a portion
of it situated in such position or positions that the brake or brakes should especi-
ally press on this surface or surfaces when the brake is applied.
In several forms of my invention, however, this wear resisting surface will
more conveniently project.
Pneumatic tyres as at present made are damaged by brakes chiefly by being
dragged upon by the brakes and torn in very minute tears frequently but still
torn not simply worn away, and I wish to obviate this by my invention.
In carrying my invention into effect, for example, with reference to pneumatic
tyres of cycles I may proceed according to many various shapes and situations
of this wear resisting surface, and this may be composed of various materials for
example, the corrugations which are made on each side of the tread on many forms
of pneumatic tyres, may be made of firmer more wear resisting quality of india-
rubber than the rest of the tyre as shown in Fig. 1 of the annexed drawings, or
instead of there being several small corrugations on each side of the tread, there
may be only one broader corrugation made of the firmer more wear resisting
material on each side or on one side of the tread of the tyre. This modification is
shown in Fig. 2. Or the wear resisting surface may be on the centre of the tread
of the tyre.
Another method would be to form the outside material of the tyre and a layer of
the canvas or other lining material or "insertion" into corrugations, and so build
up a brake resisting surface or surfaces (as shown in Fig. 3). These corrugations
or pleats of the outside and lining materials may either be made of the ordinary
rubber and canvas of pneumatic tyres pressed and consolidated together so as to
form a more wear resisting portion for the brakes to act on, or may be made of
different quality of rubber or other material with insertion of canvas, leather or
more wear resisting materials.
These or any other suitable forms of wear resisting materials may be incor-
porated into the outside surface of pneumatic or other tyres in the process of
manufacture or may be made separately as bands or slips which could be solu-
tioned, vulcanised or otherwise suitably fastened on to outside of such tyres.
To apply my invention to the rims of cycles and other vehicles especially of
motor cars, may either form a suitably shaped surface of the material of the rim
itself as of the steel or iron of rims of cycles and motor cars as shown in Fig. 4,
of the drawings, or a portion of the rim of suitable shape might be made of steel
or iron of a quality more suitable for the brake to act on; or the rim may be so

page_text: made that a band or bands of other material can be inserted into it or fastened to
it all along its length which band shall be more suitable for the brake, to act on
than the general surface of the rim. As, for instance, a band of mild steel might
be inserted or fastened all along one or both sides of a wooden rim or a band of
leather, compressed wood, vulcanite or other composition might be inserted or
fastened to a metal rim.
The same sort of method would apply to the felloes of other wheels. The object
of my invention is to supply a special surface or surfaces to wheels to enable
brakes to be applied to the wheels with greater certainty of uniform action and
with less deterioration and less damage to the wheels, and for pneumatic tyres I
aim to do this with as little loss of resiliency as possible, and incidentally but
not necessarily the braking bands would tend also to decrease side slipping.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
-
1. Constructing tyres or rims with braking surface or surfaces substantially as
and for the purposes described.
2. The improved tyre or rim substantially as described and shown in accom-
panying drawings.
