PROVISIONAL SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
We RICHARD LEE PHILPOT, of Loch View, Burnside, Rutherglen N.B.
Manager of Works, and HENRY BIRCHALL CLAYSON, of 40 Rockmount Road,
Upper Norwood, in the County of Surrey, Manager of Depôt, do hereby declare
the nature of this invention to be as follows:-
Our invention relates to an improved construction of cover for pneumatic tyres,
the object being to prevent side slipping.
We attach to the cover of the tyre, which may be constructed in any of the
well-known manners, a series of studs or projections formed of leather, hard rubber,
vulcanite fibre, woodite, or any other suitable material. These studs or projections
may be of a round, rectangular, or other form, and they may be either arranged on
the outer face of the cover in one or more straight lines with suitable spaces
between them, or they may be arranged in one or more lines in zigzag fashion.
These studs or projections may be either cemented or rivetted to the face of the
cover on the tread thereof, or they may be attached thereto in any other
convenient manner such as forming them with flat heads and passing them through
perforations in the cover so that they project through it, the flat heads of the said
pieces being on the inner side of the cover where they may be fixed in position
by solutioning a strip of canvas over them, or by solutioning them direct to the
cover.
It will be understood that our invention is applicable both to the ordinary covers
of pneumatic tyres, and to detachable covers adapted to be fitted over the ordinary
covers of such tyres, and as a further modification the studs or projections may be
mounted on, or attached to, a strip or band of any suitable material adapted to be
solutioned, or otherwise fixed, to the outer face or tread of existing plain covers.

COMPLETE SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
We, RICHARD LEE PHILPOT, of Loch View, Burnside, Rutherglen N.B.
Manager of Works, and HENRY BIRCHALL CLAYSON, of 40 Rockmount Road,
Upper Norwood, in the County of Surrey, Manager of Depôt, 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 an improvement in covers for pneumatic tyres, and
it consists in attaching to the cover, which may be constructed in any of the
well-known manners, a series of studs or projections formed of leather, hard
rubber, vulcanite fibre, woodite, or any other suitable material, the object being to
prevent side slipping.
We attain this end in the manner shown in the accompanying drawing, in
which :-
-
Figure 1 is a view in transverse section showing one method of applying the
studs or projections to the cover of the tyre.
Figure 2 is a similar view showing another method of carrying our invention into
practice.

page_text: Figure 3 is a broken view in plan showing some of the shapes the studs or
projections may assume.
Figure 4 is a view in transverse section showing a modification of the construction
illustrated by Figure 1, and
Figure 5 is a view in transverse section showing a modification of the construction
illustrated by Figure 2.
Throughout the views similar parts are marked with like letters of reference.
The studs or projections A which may be of a round, square, rectangular,
or other form, are arranged on the outer face of the cover B of the tyre in one or
more straight lines with suitable spaces between them, or they may be arranged in
one or more lines in zigzag fashion. The studs or projections A are fixed to
the face of the cover B by rivets C as shown by Figures 1 and 4, or they may be
attached thereto by forming the studs or projections with flat heads " a" and
passing them through holes or perforations in the cover B so that they project
through it as shown by Figure 2, the heads "a" of the studs or projections being
on the inner side of the cover are fixed in position by solutioning a strip D of
canvas over them as 'shown by Figure 2, or by solutionizing them direct to the
cover. As a further modification the studs or projections A may be mounted on, or
attached to, a strip or band D of any suitable material adapted to be solutioned, or
otherwise fixed, either to the inner face of the cover or to the outer face thereof.
In the former case as shown by Figure 5 suitable holes are made in the cover for
the studs or projections to pass through, and each stud or projection is preferably
mounted on an independent strip of fabric which is placed transversely on the cover,
but in the latter case the studs or projections are preferably mounted on a strip of
fabric intended to be placed longitudinally on the cover.
It will be understood that our invention is applicable both to the ordinary covers
of pneumatic tyres, and to detachable covers adapted to be fitted over the ordinary
<covers of such tyres.
We wish it to be particularly understood that we do not limit ourselves to the
precise details of construction hereinbefore described and illustrated by the
accompanying drawing, but that we hold ourselves at liberty to make such changes
and alterations as fairly fall within the spirit and scope of our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The hereinbefore described combination of parts constituting a new and
improved cover for pneumatic tyres.
2. The combination with the cover of a pneumatic tyre, of a series of studs or
projections of any suitable shape and size made of leather, hard rubber, vulcanite
fibre or other suitable hard material or composition fixed to the tread or outer part
of the said cover either in one or more lines either straight or zigzag with suitable
spaces between them, as and for the purpose set forth.
3. The combination with the cover of a pneumatic tyre, of a series of studs of any
suitable size and shape adapted to be passed through holes in the wearing face or
tread of the cover from the inner side thereof so as to project through the said
cover, and fixed to the inner surface of the cover either by having heads formed on
them or by attaching them to one or more strips of fabric adapted to be fixed to the
inner surface of the cover, as set forth.
