Improvements in Tyres for Cycles and other Road Vehicles.
I JOHN CHARLES BAYNTON TAYLOR, of St. Magdalen's, Bath in the County.
of Somerset, Gentleman do hereby declare the nature of this invention to be
as follows:-
A hollow wire tire arranged in any or all of the following ways-or in any
combination thereof-so as to adapt it to the various kinds of wheels and wheel
strains-vizt.-1st. A tire tube is made of wire twisted spirally round a cylinder
(or in any other way) the ends being joined it forms the wire-tire. 2nd. The coils
of wire may be (or not) fastened equidistant. 3rd. One tire tube in reverse order
may be enclosed in another and the cross segments joined or left free. 4th. Wire..
woven into a net work may be used to form the wire-tire tube. 5th. The wire tire
tube may be formed of rings parallel to each other and held in place by suitable
attachments. This tire tube may or may not be enclosed in-or embedded in-
or placed outside of a tire or sheath (pneumatic or not pneumatic) made of india.
rubber or any other suitable substance.

1, JOHN CHARLES BAYNTON TAYLOR, of St. Magdalen's, Bath, in the County
of Somerset Gentleman, 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 :--
1
My invention relates to improvements in tyres for cycles and other road vehicles
and an important feature thereof consists in the employment of a coiled wire
spring or springs, or other equivalent device such as spring wire rings or spring
wire woven into tubular network or gauze, for the purpose of imparting the requisite.
resiliency or elasticity to the tyre.
If a coiled spring be employed, the same may be so arranged that the coils
thereof project radially or in an approximately radial direction from the wheel rim,.
and may be combined with a tyre body formed of a rubber or other suitable tube,
or two or more such tubes with or without an outer covering and a layer or layers
of canvas or other suitable material between them. In order that my invention
may be clearly understood and readily carried into effect I will proceed to describe
the same with reference to the accompanying drawings, in which
Figure 1 shows a transverse section of one form of tyre constructed according to
my invention and provided with a coiled spring.
Figure 2 is a longitudinal section thereof.
a is the rim of the wheel and 6 is the coiled spring by which resiliency is
imparted to the tyre. This spring is embedded in a rubber tube c, around which is.

page_text: arranged an outer tube d and a protective covering or tread e. An inner lining
of canvas may be provided for the tube c in which the coil is embedded. A similar
lining or thickness may be arranged inside the tube d between it and the said
tube c.
The embedding of the coiled spring in the rubber tube c may be effected in any
convenient manner, and the said spring may either have its coils open as shown, or
they may be arranged to lie close together. Moreover instead of using a single
coiled spring extending completely around the wheel I may use a number of short
coiled springs placed end to end around the rim.
It will be understood that the diameter of the coiled spring; and the thickness
and section of the steel or other wire or the like of which it is composed may be
varied in accordance with the class of wheel or vehicle to which such coiled spring
is to be applied. Moreover instead of the coils of the spring being of circular form
they may be flattened somewhat or made approximately elliptical.
In some cases the tyre may be composed solely of the coiled spring or springs
above described without any outer cover, or I may embed the said spring or
springs in the outer tube or cover. I may also arrange the said spring or springs
between the tubes of the tyre body, or between two of such tubes, instead of
actually embedding it in the rubber in the manner referred to, and I may
employ a solid or a hollow core of india rubber or other suitable material
inside the tyre.
According to another modification of my invention instead of a coiled spring
I employ a series of spring rings arranged in positions corresponding to those of
the coils of the spring. These springs may if necessary be secured in place by
suitable attachments, or may be connected to circular wires or hoops arranged
around the wheel at each side of them. They may be used in conjunction with one
or more tyre tubes as above described with reference to the coiled spring, or they
may in some cases be used alone.
Instead of the coiled spring I may employ one or more tubes of spring wire
gauze or netting which may be combined with india-rubber tubes and with a
cover such as above referred to in a manner analogous to the said coiled
spring.
I may also instead of a single spring employ two coiled springs, respectively
right-handed and left-handed, arranged one inside the other, with the coils
connected in any suitable manner.
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. In a tyre for a cycle or other road vehicle, the employment of a coiled spring
or springs or the equivalent, for the purpose of imparting resiliency or elasticity
to the tyre, substantially as described.
2. A tyre for cycles and other road vehicles consisting of a coiled spring
combined with an india rubber or other tube or tubes and with a suitable tread or
protective covering substantially as described.
3. My improvements in tyres for cycles and other road vehicles, substantially as
herein before described with reference to the accompanying drawings.
