PROVISIONAL SPECIFICATION.
Improvements in Covers for Pneumatic Tyres.
We, JOHN WILLIAM GRIFFITHS, 20, Regent Road, Bootle, Licensed
Victualler, and JOHN FITZSIMINS, Music Teacher, 34, Berry Street, Bootle,
do hereby declare the nature of this invention to be as follows:-
Our invention relates to covers for pneumatic tyres and the object is to render
them non-slipping.
In carrying our invention into effect we proceed in or in about the following
manner. We provide a suitable width and length of appropriate material to form
the cover. This piece of material we prefer to furnish at each edge with catgut or
the like instead of the usual endless wires or thickened edges, but these latter may
if desired be used. On that part of the cover which will form the tread we form a
line of ring like projections, and right and left of this line we form other lines of
similar projections. These ring like projections may be of any convenient size or
form and arranged at any desired distance apart from each other. Rings attached
to the cover may be used instead of having them formed in or on the material.
This cover effectually prevents slipping, as the rings form suckers when wet, the
centre line of them coming in contact with the road when going straight and the
side lines when turning a corner, thus affording the rider perfect safety at all times.
In dry weather the rings or ring like projections offer no obstacle to the progress
of the wheel. We prefer the rings or ring like projections to have flat surface
where they come in contact with the road.

Improvements in Covers for Pneumatic Tyres.
We, JOHN WILLIAM GRIFFITHS, 20, Regent Road, Bootle, Licensed
Victualler, and JOHN FITZSIMINS, Music Teacher, 34, Barry Street, Bootle,
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 :-
Our invention relates to covers for pneumatic tyres, and the objects are to render
them non-slipping and less liable to puncture, and to provide an effective easily put
on and removed substitute for the usual wire at the edge of the cover, a substitute
which shall in addition be not liable to rust.
In carrying our invention into effect, we proceed in or in about the following
manner, making reference in this specification to the accompanying sheet of
drawings, in which
Rio 1 ia plan of a nortion of one of our covers flattened out

page_text: Fig. 2. is a cross section through A. B. of Fig. 1, and
Fig. 3. is a cross section of the cover in use.
Similar letters denote the same parts wherever they occur.
We provide a suitable width and length of appropriate material a (such as india-
rubber) to form the cover. This piece of material we prefer to furnish at each edge.
with catgut or the like b as a substitute for the usual endless wires or thickened
edges. The catgut may be inserted in a piping formed either on the edges of a, or
at the edges of a lining c of canvas or other material. Although we prefer to use
catgut, nevertheless, wires or thickened edges may be used if desired. On that
part of the cover which will form the "tread," we provide a line of ring-like
projections d, and right and left of this line we provide other lines of similar
projections e and f. These ring-like projections may be of any convenient size or
shape, and arranged at any desired distance from each other. We prefer however,
that they shall have a flat surface where they come in contact with the track or
road. These ring-like projections may be formed in or on the substance of the
cover, or they may be attached thereto by cementing, rivetting or in any other
suitable manner..
In Fig. 3. g is the air tube and h the rim. When catgut is employed, we prefer
to fasten the ends by hooks i and eyes j; but they may be connected together by
splicing or by any other convenient means.
Our improved cover effectually prevents slipping, as the ring-like projections
form suckers when wet, the centre line of them coming in contact with the road, or
track when going straight, and the side lines when turning a corner, thus affording
the rider perfect safety at all times. Liability to puncture is also lessened by
reason of the actual surface of the cover being kept above the track by the
ring-like projections. In dry weather the projections offer no obstacle to the
progress of the wheel. As regards the catgut, this is much superior to the usual
wires, as it does not rust and is much more easily removed and replaced.
Our invention being capable of considerable variation without departing from
the essential features of it, we do not restrict ourselves to the precise configurations,
disposition of parts relative sizes or proportions, described or referred to in the
above specification, or exemplified in the accompanying drawings.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is ;-
CLAIMS.
1. Providing the exterior of the covers of pneumatic tyres with ring like
projections at intervals along and also aside of the tread thereof, the said ring-like
projections being formed in or on the substance of the said cover or attached
thereto, the whole substantially as described in the above specification, and
exemplified in the accompanying drawings.
2. As a substitute for the usual wires employed in connection with the covers of
pneumatic tyres the use of catgut whether the said covers be constructed in
accordance with the above claim, or in any other manner, the said catgut being
retained in position in pipings formed along the edges of the cover itself, or along
the edges of a lining attached thereto, or in any other suitable or convenient
mauner, the whole substantially as described in the above specification, and
excimplified in the accompanying drawings.
3. In covers for pneumatic tyres, the improvements substantially as described in
the above specification and exemplified in the accompanying drawings.
