Merchant, do hereby declare the nature of this invention to be as follows:-
An improved cycle tire which consists of a snake spring internally and inlaid
through centre of india rubber strengthened by canvas bore tire the tire will be
manufactured with a joint or jointless to suit the views of users the tire with
joint will be tightly jointed by means of a mettel union to slot together and
plugged together by means of a hollow threaded tube bolt stopped airtight upon
the internal end and capped with an ordinary cycle valve upon the external
end in order that the user may blow air into the tube with an ordinary cycle
pump the tire will be made to fit any rim now manufactored therefore puntures
in tire does not effect the rider or cause him to become stranded.
I, ALFRED EMANUEL WRIGHT, of The Aviary, Ash Vale, Aldershot, Surrey,
Slate Merchant, 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 an improved tyre the object being to produce a tyre
possessed of sufficient resiliency to reduce to a considerable extent the vibration
due to the passage of the vehicle, to which such tyre is fitted, over the inequalities
of the road, and to produce a tyre, possessing to a very considerable extent, the
advantages of the ordinary pneumatic tyre, without the disadvantage of being
liable to be rendered non-effective by puncture, and to this end, I provide a tyrė
consisting of a spiral spring of sufficient diameter enclosed within a rubber tube
and which is reinforced with one or more layers of canvas, rubberized canvas,
or the like, and upon the outer surface of the whole, a tread of suitable form and
material may be arranged. This improved tyre is preferably made with separated
extremities, which are united, so as to form a circular tyre, by the employment
of a iunction or connecting piece, as hereinafter described.

In order that this invention may be more fully understood, I will now procced
to describe same with reference to the accompanying drawings, in which:-
Fig. 1, is a sectional view of the ends of a tyre constructed according to this
invention,
Fig. 2, is a similar view, shewing the extremities of the tyre, joined or con-
nected together.
The
In carrying this invention into practical effect, and in the form I prefer to
employ it, the tyre consists, of a spiral spring s of sufficient length, the extremities
of which are connected with the junction or connection piece, comprising the
tubular sleeve b and the sleeve ₁ formed with reduced extremity .
springs, the tubular sleeve b and a part of the sleeve b¹ is enclosed within the
rubber tube a, strengthened by reinforcements of canvas or other suitable
material c, and upon the outer surface of the whole, a tread c¹, of rubber or other
suitable material.
In order to connect the extremities of the tyre together, and so as to make
a flush joint, the reduced extremity 62 of the sleeve b¹, is slipped into the
sleeve b, until the holes or perforations 9 and the corresponding holes g¹ in the
reduced extremity 62 of the sleeve b', coincide, any suitable cement being placed
between the meeting edges, when the whole is secured together by a bolt d,
formed with a screw threaded head d, designed to enter the upper holes g g',
and with an enlarged screw threaded part d², designed to engage the lower
holes gg. The bolt d is provided with a screw threaded stem d³, designed to
pass through the ordinary valve hole in the rim, where it is secured in position
by a suitable nut, while the said bolt d may be formed hollow throughout part of
its length so as to receive a valve of any suitable and well known form to allow
of air being pumped into the tyre to act as a further supporting medium in
addition to the spiral spring s, but I do not consider the pumping of air into
the tyre to be essential as the spring is sufficient to give the required elasticity.
In the drawings the sleeves 6 6 have been shewn with straight parallel sides,
but in practice such sleeves are preferably formed with a curvature corresponding
to that of the rim upon which they are to be fitted, while the remainder of the
tyre is sufficiently flexible to readily adapt itself to the curvature of the rim.
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:
1/. A new or improved tyre consisting of a spiral spring such ass, the
extremities of which are connected to sleeves b 61 forming a junction or connec-
tion piece, and enclosed within a rubber tube such as a, reinforced by one or
more layers of canvas or other suitable material such as c, and furnished with a
tread of rubber or other suitable material such as c¹, and connected together at
the extremities by a reduced end of one of the sleeves taking into the other,
where it is secured in position by a screw bolt such as d furnished with a screw
threaded head such as d, and an enlarged screw threaded parts such as 2, screw-
ing into screw threaded holes or perforations such as g formed in the one sleeve,
and into corresponding screw threaded holes or perforations such as g¹ formed in
the reduced extremity of the other sleeve, and fitted or not as required with a
suitable valve to allow of air being pumped into the said tyre; the whole arranged
and constructed substantially as herein described and shewn with reference to
the accompanying drawings and for the purposes specified.
2. The combination with a tyre consisting of an inner coiled spring such as s
contained within an enclosing tube such as a reinforced with one or more layers
of canvas or other suitable material such as c, and provided with a suitable tread
such as c¹; of a junction or connection piece consisting of tubular sleeves such
asb connected with the extremities of the spring s, one of the said sleeves
being furnished with a reduced extremity such as designed to enter the other
sleeve, and each furnished with an upper and lower screw threaded hole or per-

page_text: foration such as 9 9¹ designed to be engaged by the upper and lower screw
threaded parts d¹ d² of a connecting bolt d, substantially as herein described
and shewn, with reference to the accompanying drawings and for the purposes
specified.
