PROVISIONAL SPECIFICATION.
Improved Elastic Non-puncturing Tyre for Cycles and other
Vehicles.
RUSSELL WILLINGTON Lancaster Lodge 399, Goldhawk Road Hammersmith
W. do hereby declare the nature of this invention to be as follows:-
Tyre will consist of, a round or oval shaped cork, suitable to size of tyre, cut
through the middle, forming two equal halves, between the two halves, will run
one, two or more rubber ropes, half inch diameter more or less, to form spring,
the two halves with rubber between slightly let into each, will have rubber bands
stretched over the whole to keep same in position, the tyre will be continued until
long enough, with halves of cork and rubber rope, when long enough, the ends
of rubber will be tightly fastened and covered with cork, forming a circular
ring, the cork will then be wrapped with one or more envelopes of thin rubber
solutioned together or otherwise fastened & can then be stretched and let over rim
of cycle or other vehicle thus making tyre complete.

COMPLETE SPECIFICATION.
An Improved Elastic Non-puncturing Tyre for Cycles and other
Vehicles.
I, RUSSELL WILLINGTON, formerly of Lancaster Lodge, 399, Goldhawk.
Road, Hammersmith, W. but now of 9 Cornhill in the City of London,
Engineer, 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 improvements in the construction of tyres for cycles.
and other vehicles, and has for its object to provide a resilient tyre which will not
be liable to injury by puncture.
In carrying out my invention I propose to construct the tyre from cork:
preferably semicircular in cross section and made for convenience in sections or
lengths.
These corks are placed with their flat surfaces in opposite directions, and are formed.
with one or more grooves, within each of which a rope or band of rubber is placed.
The corks are thus separated by one or more ropes or bands of resilient material
which allows them to approach each other on pressure being applied, but will
cause them to resume their original position and shape when the pressure is
removed.
The ends of each rope or band referred to herein are secured to each other forming
continuous ropes or strands of rubber.
The cork sections are connected together by means of rubber or other bands.
encircling them, and rubber or other covers or sheaths are employed to complete
the tyre.

page_text: The rubber rope or band placed between the cork sections may be of any
suitable shape and one or more may be used.
According to one arrangement two circular ropes or bands are employed placed
in corresponding grooves, but rectangular or diamond shaped bands may also be
employed. Ou enlarging the rope or band a single one may serve placed at
the centre.
In order that the invention may be more clearly understood reference is had to
the accompanying sheet of drawings in which
Fig. 1 is a cross section of a tyre according to one arrangement.
Fig. 2 is a side elevation with parts removed of the same tyre and
Figs. 3 to 6 are cross sections of modifications.
Referring to Figs. 1 and 2 the cork rings or sections A are of similar shape
being semicircular in cross section so that when placed close together with their flat
faces almost touching a circular tyre is formed. The sections when placed together
to form the tyre may be caused to break line at their points of contact being placed
alternately.
These sections are formed with the rounded groove B, one being placed at each
side in the flat faces, and the rubber rings C are placed in these sections between
the two faces. The cork sections are thus held at a short distance from each
other but, on any pressure being applied, they are brought closer together, the
rubber ropes or bands serving as springs. When great pressure is applied such as
may occur at the point of contact with the ground, the cork sections may actually
touch compressing the rubber springs to the fullest extent possible.
The sections are connected together by the rubber bands D placed at short
intervals apart and binding the sections together tightly. Besides these bards an
inner rubber sheath E employed encircling the cork and rubber, and an outer
sheath or tube E' is also used made from rubber, rubber and canvas or other
suitable material.
As shown in Fig. 3 the arrangement is similar to that already described, but the
rubber ropes or bands C₁ are of rectangular form and the grooves B' are of similar
shape.
As shown in Fig. 4 the ropes or bands C' are of diamond shape in cross section
and the grooves B are of wedge form.
In Figs. 5 and 6 a single rubber rope or band is employed the rope or band C³
shown in Fig. 5 being of rectangular form and considerably larger than the ropes
or bands already. referred to.
The groove B³ in cross section is also of rectangular form to receive the rope or
band. The rope or band C in Fig. 6 is of diamond or square shape in cross
section and the single groove B is of wedge shape to receive it..
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,
(1) A new or improved tyre for cycles and the like formed from two semi-
circular rings of cork formed with grooves and separating ropes or bands of rubber
placed in the said, grooves substantially as described and for the purposes
specified.
(2) In an improved tyre for cycles and the like, the combination with two cork
semicircular rings formed with grooves of rubber ropes or. bands in the grooves, and
rubber rings encircling the cork and sheaths completing, the tyre substantially as
described and shown in the accompanying drawings and for the purposes
specified.
