IMPROVEMENTS IN TYRES FOR VELOCIPEDE AND OTHER WHEELS
Year: 1885

page_text: We WILLIAM HENRY BATES, Manufacturer, and HUGH FAULKNER, Manager,
both of St Mary's Mills, Leicester in the County of Leicester do hereby declare
the nature of our invention for "IMPROVEMENTS IN TYRES FOR VELOCIPEDE AND
OTHER WHEELS," to be as follows:-.
The object of this invention is to provide a tyre for velocipede and other wheels,
which may firmly hold to the wheel without the aid of cement, and be capable of
easy removal, either wholly or partially, for the purpose of repairing the wheel
spokes..
t
This is a great desideratum, and absolutely to fulfil both conditions, has hitherto
probably been practically impossible.
Many attempts have been made, but the results, so far as we are aware, have not
been satisfactory.
:
In carrying out our invention, we employ a flexible metal core, round which we
lap or roll the rubber compound, of any desired thickness, and vulcanize it in the
usual way.
The flexible metal core which we prefer to use, is a chain, which is drawn to
tension before being coated with the rubber.-A chain is however liable to cut
through the rubber while in use, and we therefore first cover the chain with
canvas or other suitable material, or braid it, which will prevent its cutting
through the rubber:
In making the tyres, we prefer to prepare the materials therefor in long lengths,
which are cut up to the requisite lengths for the tyres it is desired to make.-The
ends of the pieces of chain are then connected together, and the ends of rubber are
joined by solution, or in any other suitable manner, and the rings thus formed are
vulcanized in the usual manner.
The tyre being made complete before vulcanizing, the metal core is protected
from danger of corrosion.
The length of the pieces to form the tyre must be such that the length of the
metal core shall only slightly exceed the circumference of the wheel to which the
tyre is to be applied, the compressibility of the rubber allowing for the insertion
of the tyre on the felloe.-The metal core thus practically serves to bind the tyre
on the felloe, and the use of cement is unnecessary, though it may of course be used
if preferred.
Although we have particularly referred to rubber, we would here remark that we
may also employ other vulcanizable elastic compounds.

We WILLIAM HENRY BATES, Manufacturer, and HUGH FAULKNER, Manager,
both of St Mary's Mills, Leicester in the County of Leicester 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 a novel construction of tyre for velocipede and other
wheels having hollow felloes which will more firmly hold to the wheel than here-
tofore, and be capable of removal for repairing the wheel spokes and for other
purposes.
.

Facility of removal and replacement, with a firm hold, is, a great desideratum
in respect to velocipede wheel tyres, and though many attempts have been made to
attain this result, they have not proved, so far as we are aware, satisfactory..
In carrying out our invention, we employ a flexible metal core or cores, which
we enclose with the ends joined in canvas or other fabric, and cover to the desired
thickness with rubber or other, vulcanizable compound, which (with the joined core
inside) is subjected to the process of vulcanization in the usual way.
In the accompanying Drawing, we have shown, in side view and cross section, a
portion of a tyre constructed according to our invention.
A is the flexible metal core, say a chain of any suitable construction.-B is a
covering of some fabric, as canvas, or it may be a braided tube, and C is the rubber
or other vulcanizable compound forming the outside of the tyre.
J
The canvas or braided covering is used to prevent the flexible metal core cutting
through the rubber or other compound while the tyre is in use.
In making our improved tyre, which we prefer to do in long lengtbs, we first
coat the flexible metal core with a thin coating of india rubber to form an even
surface, and we then lap or roll round it a strip or strips of canvas or other suitable
material, which has been previously coated with rubber or other compound, or we
braid a tube round the core in a suitable braiding machine.
{
'
We then coat the fabric-covered metal core with the rubber or other vulcanizable
compound to the required thickness for the tyre, by any of the methods well known
to manufacturers of this class of goods.
From the long length of material thus prepared, we cut a length necessary to
make a tyre of a given size, and we connect the ends of the core.-
-We then join,
by means of solution, the ends of the rubber or other compound, and the tyre thus
formed is vulcanized in moulds, or in any other well-known manner, with the
joined flexible core inside.
A tyre produced in this manner, and of a size adapted to the wheel, will have
a firm grasp on the wheel, the metal core practically tying the tyre onto the
felloe. If desired however, cement may also be employed to attach the tyre to
the felloe.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we would here remark
that we are aware a wire has been inserted in rubber tyres for bicycle wheels after
vulcanization, and we are also aware that this wire has been inserted through a

page_text: canvas or other tube contained in the tyre, also after vulcanization.
We are also
aware that an iron or other wire, or segments of wire, have been embedded within
the rubber tyre, for the purpose of strengthening the tyre, and we do not therefore
make any claim for a wire or canvas tube so used, either alone or in combination,
or for strengthening the tyre by embedding therein a wire or segments of wire,
neither do we. make any claim to a flat metal core as described and claimed in
specification No 4812 of 1885 but what we claim is
1. A tyre for wheels of velocipedes and other vehicles constructed in the manner
herein shown and described.
2. In the manufacture of tyres from rubber or equivalent compounds for the
wheels of velocipedes and other vehicles, the use of a flexible metal core which is
enclosed or inserted in the rubber or other compound, and its ends secured together,
previous to the vulcanizing operation as set forth.
