PROVISIONAL SPECIFICATION.
Improvements in and connected with the Tyres of Cycles and other
Vehicles.
I, JOHN MCCORMACK, of 82, Windsor Street, in the County of the City of
Glasgow, India Rubber and Waterproof Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention which relates to the tyres of cycles and other wheeled vehicles
has for its object to retain the outer cover of the tyre securely to the rim
without the liability of its being displaced at any time by a method and means
now to be described.
The ends of the outer cover are formed with the usual eye extension at either
ends thereof and into and through these eyes or annual pockets I insert a hoop,
rod or band composed of cane, whalebone or other nonstranded fibrous material,
natural or artificial other than metal which has previously been treated in order
to take out the stretch or remove any tendency to undue expansion. The approxi-
mately inextensible cane or other hoop, rod, or band, has its ends connected by a
lap joint incircled by a ferule collar, or its equivalent, or between the ends to
which they are connected, may conveniently be interposed a short length of spiral
br other spring in order to render the cover sufficiently extensible to be placed
in the rim.
The method of taking out the stretch of the cane, or other fibrous material which
constitutes an especial feature of my invention and one I have found to be highly
successful consists in causing the cane or other material to take up a sufficient
amount of moisture under pressure or not. After this operation, I pass the cane
or other material between rubber or other rolls when it becomes extended in
the 'direction of its length to the maximum extent and remains so. By this
means it becomes sufficiently impervious to resist moisture incidental to cycling
during wet weather or when the roads are in a plastic condition.
Dated this 12th day of November 1898.

page_text: 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 which relates to the tyres of cycles and other wheeled vehicles
has for its object to retain the outer cover of the tyre securely to the rim
without the liability of its being displaced at any time ensure lightness and
overcome certain disadvantages common to the wires now in use by a method
and means now to be described.
In order that my invention may be properly understood and readily carried
into effect I have hereunto appended one explanatory sheet of drawings in the
three figures of which corresponding parts are marked with the same letters of
reference.
Figure 1 is a perspective view of part of a cycle tyre embodying my improve-
ments.
Figure 2 is a side elevation partly in section illustrating the lap joint, and
Figure 3 is a perspective view of a rolling machine employed in the stretching
operation.
The edges of the outer cover A, are formed with the usual eye extensions 13,
and B', at either end thereof, and into and through these eyes or annular
pockets, B, and B', I insert a hoop, rod or band C, composed of cane, whalebone,
or other nonstranded fibrous material, natural or artificial, other than metal,
which has previously been treated in order to take out the stretch or remove any
tendency to undue expansion. The approximately inextensible cane or other
hoop, rod or band C, has its ends connected by a lap or splice joint D, incircled
by a ferule, collar, or its equivalent E; or between the ends to which they are
connected may conveniently be interposed a short length of spiral or other
spring, not shown on the drawings, in order to render the cover sufficiently
extensible to be placed in the rim. The method of taking out the stretch of the
cane or other fibrous material which constitutes an especial feature of my inven-
tion, and one I have found to be highly successful, consists in causing the cane
or other material C, to take up a sufficient amount of moisture, under pressure
or not.
F
After this operation I pass the cane or other material between rubber-coated
or other rolls Fig. 3, when it becomes extended, in the direction of its length
to the maximum extent and remains so. By this means it becomes sufficiently
impervious to resist moisture incidental to cycling during wet weather or when
the roads are in a plastic condition.
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:-
In tyres for cycles and other wheeled vehicles securing the outer cover to
the rim by means of a hoop or band of cane, whalebone, or analogous animal or
vegetable material, treated by saturation and rolled in order to minimise the
tendency to stretching, and operating substantially as and for the purpose herein-
before described, and shown on the accompanying sheet of drawings.
