PROVISIONAL SPECIFICATION.
Improvements in or applicable to Pneumatic or other Inflated Tyres.
I, JOHN BRINDLE, of 49, North Road, Preston, in the County of Lancaster,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to form the running surface of a pneumatic or
other inflated tyre with improved means for preventing slipping for giving increased
bite on the ground and for (to a certain extent) preventing liability to puncture.
To this end I incorporate or manufacture in one piece with the running surface of
the tyre a number of projections knobs or studs arranged at suitable distances from
each other. These projections knobs or studs may be in the form of pyramidal or
circular cones either pointed or truncated or they may be in the form of rounded
buttons or mushroom heads or of any other desirable shape. They may be arranged
either in rows longitudinally or transversely of the running surface of the tyre or
they may be arranged in diagonal or irregular lines as may be found most
effective.

COMPLETE SPECIFICATION.
Improvements in or applicable to Pneumatic or other Inflated Tyres.
I, JOHN BRINDLE, of 49, North Road, Preston, in the County of Lancaster,
Mechanical 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:-
This invention has for its object to form the running surface of a pneumatic or
other inflated tyre with improved means for preventing slipping for giving increased
bite on the ground and for (to a certain extent) preventing liability to puncture.
To this end I incorporate or manufacture in one piece with the running surface of
the tyre a number of projections knobs or studs arranged at suitable distances from
each other. These projections knobs or studs may be in the form of pyramidal or
circular cones either pointed or truncated or they may be in the form of rounded
buttons or mushroom heads or of any other desirable shape. They may be arranged
either in rows longitudinally or transversely of the running surface of the tyre or
they may be arranged in diagonal or irregular lines as may be found most
effective.
The accompanying drawings shew some of the forms of projections knobs or studs
which I employ in carrying out my invention.
Figs. 1 and 2 are a section and plan view respectively of the running surface of
an ordinary pneumatic tyre in which the projections take the form of bee-hive-
shaped cones a being the body part of the outer covering of the tyre and 66 the
projections.
The succeeding figures illustrate other forms:
Figs. 3 and 4 shew a form of rounded button or mushroom head;
Figs. 5 and 6 a truncated cone; and

page_text: Figs. 9, 10, and 11 shew a modification of the above in which the projections are
of an elongated form running round the tyre in parallel planes.
In the several figures the projections knobs or studs are shewn arranged directly
opposite to each other but they may obviously-without departing from the nature
of my said invention-be arranged in alternate positions.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In combination with the ruuning surface of a pneumatic or other inflated tyre the
use or employment of projections knobs or studs substantially as hereinabove
described and shewn for the purpose or purposes set forth.
