Improvements in and relating to Elastic Tyres of Cycles and Other
Vehicles.
I, JOHN ROOSE TAYLOR of Laverstoke Villa, Uttoxeter New Road, Derby in the
County of Derby, Draper, 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:—
The objects of my invention are to provide a tyre for cycles and other vehicles
which will minimise vibration and side slipping or 'skidding,' be noiseless when
in use, will possess a certain amount of resilience and at the same time will not require
the constant attention nor be subject to the inconvenience and annoyance of being
punctured, as is the case with the now well known pneumatic tyres.
In describing my invention reference will be had to the accompanying sheet of
drawings upon which Figures 1 and 2 are cross sections shewing the application of
my invention to the construction of cycle tyres as will be hereinafter explained.
In carrying out my invention I employ strips or layers A of any suitable fibre such
as felt, cocoa fibre, ordinary cloth or the like, according to the amount of resilience
required; between these strips or layers of fibre I place a substance of cork B
saturated or impregnated with a solution of india-rubber; the cork being of a
powdered, granulated or small chip form, is first soaked or steeped in naptha and
then thoroughly mixed with rubber solution the proportion of cork to rubber solution
being varied as desired, I do not however bind myself to any particular method of
saturating or impregnating the cork with solution; the cork thus prepared is spread
upon the layers of fibre aud the whole pressed together and if necessary afterwards
trimmed to any desired shape or contour. An outer covering C is finally spread over
the tyre thus formed, this outer cover being also of cork saturated with rubber
solution, the cork in this case being finely powdered or granulated and used thinly so
that it can be spread or painted on with a brush and may be made of any degree of
hardness.
The road surface of the tyre may be finished with any desired surface; for example
annular corrugations D are shewn upon Figure 2 but I am of opinion that in practice
the plain finish shewn upon Figure 1 is all that will be required; the covering of
cork saturated with rubber solution effectually prevents side slipping or 'skidding'
which is one of the evils of the pneumatic tyres or any rubber tyre of large
diameter.
may form my improved tyre of any desired section and to fit any section of rim,
and wish it to be understood that I do not bind myself to the particular sections
shewn upon the accompanying drawings, which are for the sake of illustration only.
It will be understood that I may combine various kinds of fibre in the same tyre,
for instance, the layers may be alternately of cocoa fibre, felt, cloth or the like, or, I
nay employ the most resilient fibre nearest the road surface, or vice-versa.
I wish also to state that I do not bind myself to any particular method of fixing my
improved tyres in the rims of the wheels, the sections illustrated are suitable for a
cycle, being simply sunk into a deep rim E for convenience of access to the spokes F.

page_text: Again, it is not necessary to my invention that the whole of the tyre shall be
constructed as shewn, the inner part (i.e. the part fitting in or fixed to the rim) may
if desired be of pure rubber or the like and the other part solutioned or cemented
thereto in any well known manner.
The different strips or layers of fibre and cork are carefully arranged to break joint,
and, in the manufacture any desired machine press or mould may be used to obtain
the section or form required.
A small quantity of loose fibre may be mixed with the cork if desired to assist in
cementing same together, for this perhaps cocoa fibre would be the most appropriate
and I may if desired combine small quantities of other light substances, such as
sawdust with the cork, but the principal ingredients are cork and rubber solution.
In the case of a hard tyre being required for heavy road vehicles and the like I may
reduce the layers of fibre to a minimum or even dispense with them altogether and
simply build up the tyre of cork, in slabs, saturated or impregnated with rubber
solution.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
The improved tyre for cycles and other vehicles formed either wholly or partly of
cork saturated or impregnated with a solution of india-rubber, in combination with
fibre, substantially as described and illustrated.
Dated this 7th day of April 1897.
