We GEORGE HAYDON and WILLIAM VAIL of Clarence Yard Manor Place
Walworth in the County of Surrey Engineers, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to prevent the wheels of cycles from skidding on
wet or greasy roads.
According to this invention we mould or cast round the tyres periphery a series

COMPLETE SPECIFICATION.
Improvement relating to the Tyres of Cycles.
We, GEORGE HAYDON and WILLIAM VAIL, of Clarence Yard, Manor Place,
Walworth, Engineers, 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 this invention is to prevent the wheels of cycles from skidding on
wet and greasy roads.
According to this invention we mould or cast around the periphery of the tyres a
series of diagonal projections so as to give a firm grip on the road on which the
wheels are running.
Our invention will be readily understood by the following description having
reference to the accompanying drawing, on which
Fig. 1 shews in plan view a portion of a wheel tyre having diagonal projections
upon the tread, or external periphery, according to our invention.
Fig. 2 shews a section of the tyre shewn at Fig. 1, a so-called pneumatic or air-
pressure tyre being illustrated, merely to shew the application of the invention, for
it will be obvious that the aforesaid diagonal projections may be applied to other
types of elastic tyres used on velocipede wheels.
Figs. 3 and 4 shew slightly varied arrangements of the aforesaid diagonal
projections.
A are the diagonal projections, slightly standing out from the surface B of the
tyre, as will be evident from an inspection of the section Fig. 2. These projections
may extend entirely across the tread of the tyre as shewn, or may only extend
partially across the tread if so desired, as we do not limit ourselves as to the length
of such diagonal projections, and the said projections may form any angle with
the tyre either to the right or left hand, that shewn in Fig. 1 inclining to the
right.
In some cases the diagonal projections may have a double inclination as shewn at
Fig. 3, or as at Fig. 4, and still come well within the scope of our said invention, so
that the wheel when running on the road will run smoothly from one projection to
another, and yet slipping or skidding will be entirely prevented and a firm grip on
the road will be maintained in all weathers.

page_text: 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 :-
:-
In elastic tyres for velocipedes and the like, the diagonal projections A formed
upon the running surface of such tyres, all acting substantially as and for the
purposes herein described with reference to the accompanying drawings.
