Improvements in Pneumatic Tyres.
I, WALLACE ATHERTON MCCURD, of 83, Beresford Road, Harringay, London,
Cycle Agent, do hereby declare the nature of this invention to be as follows:-
The tyre consists of a rubber & canvas outer cover and an inner tube. The
essential point of this invention is that the outer cover is divided, thereby having
two ends, which are cut at corresponding angles, and either sealed up or left open,
so that the whole tyre is in one long strip & can be attached or detached from the
wheel almost instantaneously. The outer cover is fixed to the rim of wheel by
wires, cords, or other usual means-the ends of which are held in position by a
catch arrangement, the extreem ends of outer cover being held together by
similar arrangements. The inner tube is cut and sealed up at angles identical
with that of outer cover; this being placed inside of cover the whole is fixed to
wheel and inflated. A flap or continuation of one end of cover is arranged to
prevent dirt or wet getting into the division.

Improvements in Pneumatic Tyres.
I, Wallace Atherton McCurd, of 83, Beresford Road, Harringay, in the County
of London, Cycle Agent, 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 :-
My invention relates to improvements in pneumatic tyres, which consists of an
india rubber and canvas outer cover and an inner pneumatic tube. The essential
point of this invention is that the outer cover is divided thereby having two ends,
which are cut at corresponding right angles and either sealed up, or left open so
that the whole tyre is in one long strip and can be attached or detached from the
rim of wheel almost instantaneously.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1 is an elevation of the rim of a wheel with the tyre attached.
Fig. 2 is a view of Fig. 1, before the pneumatic tube and the tyre cover is fixed
to the rim of the wheel.
In carrying my invention into practice I construct a pneumatic tube sealed at
both ends and over this said tube I fix a divided india rubber and canvas cover h.

page_text: In each edge of the cover h I insert a wire, the said wire is provided with a butt or
knob d at one end and a loop e at the other end. In the rim g of the wheel on each
side I cut a key-hole b and over this said key-hole b I provide a metal slide c to
cover the hole and to keep the dirt out. A short distance from the slide c on each
side of the rim g I drill or punch a hole a for the purpose of securing the loop & to
the hole a by a pin or bolt f.
The outer cover is fixed to each side of the rim of wheel by passing the butt or
knob d on one end of the end of tyre cover h through the key-hole b and down the
slot, when the slide c is pushed along to prevent it moving, the other end is fixed
by putting a pin f through the holes a in rin and the loops e.
When the inner tube and cover is fixed to the rim of wheel the outer cover shows
a division by means of one end of the tyre passing in under the other end of the
cover up to the dotted line j, thus it is overlapped and the tyre is inflated. The
flap k or continuation of one end of the cover is arranged to prevent dirt or wet
getting into the division.
said
Having now particularly described and ascertained the nature of my
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In pneumatic tyres, the combination of a single length pneumatic tube and
cover inserted in a single length cover, substantially as described.
2. In pneumatic tyres, a single length cover constructed and fixed to the rim of
a wheel, substantially as described.
3. As an article of manufacture a single length cover for pneumatic tyres
as above described in this Specification and according to the accompanying
drawing.
