I, GEORGE ROBERT BROWN, of No. 15 Binfield Terrace, Chingford, in the County
of Essex, Commercial Traveller, do hereby declare the nature of this invention to be
as follows:-
My invention relates to means of constructing and fixing elastic tyres to wheels
such as are used for bicycles tricycles and other vehicles, the principal object which I
have in view being to put on the clastic tyre without material strain, and to hold it
securely on the rim of the wheel.
For this purpose, I make the wheel as usual with a rim of trough shape, and I attach,
by the process of vulcanising, a caoutchouc ring to a light trough shaped ring which
is divided at one part of its circumference or at several parts thereof.
This ring or
set of ring segments, having the caoutchouc ring made to adhere in its hollow by
vulcanising, is sprung on and into the rim of the wheel in which it is secured by
rivets or otherwise. The caoutchouc tyre being held by adhesion and not by its
elastic strain, should a portion of it be damaged, this can be cut out along with a
portion of the ring to which it adheres, and a fresh segment of ring and adherent tyre
can be introduced in its place, thus rendering it unnecessary to replace the whole
tyre.

page_text: An Improvement in Wheels with Elastic Tyres.
I GEORGE ROBERT BROWN of 15 Binfield Terrace Chingford in the County of
Essex Commercial Traveller 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 means of constructing and fixing elastic india rubber tyres
to the folloes or rims of wheels such as are used for bicycles, tricycles, and other
vehicles, the principal objects which I have in view being to put on the elastic tyre
without material strain and to hold it securely on the rim of the wheel.
The nature of my said invention and the manner in which the same is to bo
performed or carried into practical effect will be readily understood on reference to
the accompanying drawings and the following explanation thereof.
For the purposes of my invention I make the wheel as usual with a rim or felloe of
trough shape preferably semi-circular as shown in transverse section at a, a, Fig. 1.
on the drawings, and I attach the same to the spokes by rivetting in the ordinary
manner, and I drill holes through this rim or fellow between the spokes at as many
places as may be thought necessary.
For the tyre I take a metal ring b, b preferably trough shaped and of thin material
(see section Fig. 2) which may be divided at one part of its circumference only or
formed in several parts or sections and I fix therein screws or rivets c, c at points
corresponding with the holes drilled in the rim or felloe a, a of the wheel and I
then attach to the interior thereof a strip or lining d, d of india rubber which will
become hard on being vulcanized.
Inside this ring b, I then place the india rubber cord e, e of a quality which will
remain soft on being vulcanized (see Fig. 3) and I unite the two india rubbers (hard
and soft) by varnishing or cementing them together in the usual weil known manner.
I prefer to cover the outside also of the ring b, b with a strip of soft rubber ƒ, ƒ
similar in quality to the rubber cord e, e (see section Fig. 4) as the covering, of
soft rubber prevents all jarring and noise. After making in the manner above
described, the whole tyre is subjected to vulcanization which may be done in moulds
or by the "open cure process as may be most convenient.
This india rubber tyre with its metal core or ring b, b (and screws or rivets c, c)
firmly secured thereto either in a ring divided at one point or in several sections or
segments is then secured by the screws or rivets c, c'in the hollow of the rim or
fellow a, a of the wheel as shown in transverse section at Fig. 5 and in longitudinal
section at Fig. 6, and it will be evident, that the caoutchouc e, e is not strained or
stretched in any way and should a portion thereof be damaged this can be cut out
along with a portion of the metal ring or core b, b to which it adheres, and a fresh
segment of ring and adherent tyre can be introduced in its place, thus rendering it
unnecessary to replace the whole tyre.

page_text: 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
The improvement in wheels with Elastic tyres substantially as hereinbefore
described and illustrated by the drawings annexed consisting of an india rubber tyre
secured by vulcanization to a ring of metal which is rivetted screwed or bolted to the
rim or felloe of the wheel.
