Improvements in and connected with Protectors for Pneumatic
Tyres.
I, Alfred ERNEST COOPER, of 39, Warwick Road, Maida Vale, London,
Civil 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 :-
The object of my invention is to prevent the puncturing of pneumatic tyres, and
at the same time do away with or lessen the danger of side slipping so common
with all the india-rubber tyre covers now in use. It is applicable to single tube
tyres, as well as to those having an inner air tube and an outer cover, and in
carrying out my invention, I proceed in or in about the following manner, that is
to say,
I attach in any suitable manner to the tread of the main elastic tyre a
protector made of woven wire somewhat similar in character to that used for
brushes of dynamos. Where the protector is used as an outside cover, it is
attached to the main tyre by placing it round the latter when in a deflated state,
and then inflating. In the case of its being used between the air-tube and rubber
cover, it is proposed to place metal studs at intervals which will project through
the rubber cover for the purpose of increasing its frictional hold on the ground,
and preventing the tyre from slipping sideways.
This protector covers the tyre circumferentially, and is so wide and so curved
that it embraces the tread portion or say approximately from one third to one half
its cross section.
In its cross sectional form I prefer the cover to be fluted on the outside. The
wire may however be woven into any suitable pattern, and may be ribbed, grooved,
or studded with any kind of isolated, connected or continuous projections or other
formations on its outer surface, the main object being to present a surface which
shall be non-slipping.
In order that my invention may be the more readily understood, I make reference
to the accompanying sheet of drawings, in which Figs. 1. and 2. are isometrical
end views of a protector applied as an outside cover to single and double tyres,
and Fig. 3. a similar view of it placed between the air tube and its india-rubber
cover. Similar letters refer to the same parts. a is the rim, b the air-tube, c the
india-rubber cover, d the wire protector, e studs projecting through c.
I do not confine myself to the precise details, configurations, relative proportions
or disposition of parts as shewn in the drawings, as any or all of them may be
varied without departing from the invention.
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.-
A protector for pneumatic tyres, and consisting of a woven wire ring surrounding
the inflated tube and embracing the tread portion of the said tube, the whole
substantially as described in the above specification, and exemplified in the
accompanying drawings.
