PROVISIONAL SPECIFICATION.
Improvements in Tyres for Wheeled Vehioles.
We, HENRY IVAN GOULD of 115 Falmouth Road, Engineer and JAMES
WILLIAM BENNETT of 41 Eastcheap, Advertisement Contractor, both in the County
of London do hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in tyres for wheeled vehicles, in which the
elastic properties of a hollow annular air chamber are utilised to reduce vibration,
and has for its object the prevention of slipping or skidding which obtains in the.
case of ordinary tyres of circular, or approximately circular cross section when
such vehicle to which they are applied is caused to turn sharply when running.
In carrying our invention into effect, we construct the hollow tyre in such a
manner that the tread, or surface which normally bears upon the track, projects
outwards from the entire breadth of the tyre, so that two shoulders are formed, one
on each side of the projecting tread, aforesaid. These may be made curvilinear,
or of any other suitable shape, and the whole tyre of any suitable elastic substance,
material, or composition. The inner part of the tyre may be shaped to conform to
the shape of the rim of the wheel to which it is adapted. When the vehicle is
running in a straight line, the traction is upon the projecting tread alone, but when
turning a sharp corner, or rounding a curve, the angularity of the wheel due to
turning, causes one of the shoulders before described to bear upon the track, thus
presenting a double surface, which precludes any tendency to slipping or skidding.
Our invention is applicable to inflated and other elastic and resilient tyres.

Improvements in Tyres for Wheeled Vehicles.
We HENRY IVAN GOULD, of 115 Falmouth Road, Engineer, and JAMES
WILLIAM BENNETT of 41 Eastcheap Advertisement Contractor, both of the County
of London 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 improvements in tyres for wheeled vehicles in which
the elastic properties of a hollow annular air chamber are utilised to reduce
vibration, and has for its object the prevention of slipping or skidding, which
obtains in the case of ordinary tyres of circular or approximately circular cross-
section, when such vehicle to which they are applied is caused to turn sharply
when running.
In order that our invention may be the better understood, we have appended the
accompanying sheet of drawings in which
Fig. 1 represents a cross section of a preferred form in the position of a vertical
wheel.
Figure 2 shews the same in the position of an inclined wheel, as when rounding a

page_text: Similar letters of reference indicate corresponding parts throughout the several
views.
In carrying our invention into effect we construct the hollow tyre in such a
manner that the tread or surface which normally bears upon the track, projects
outwards from the entire breadth of the tyre, as shewn by the drawings, in which
a is the hollow tyre, and d d¹ the projections thereof, said tyre being held within the
rim of the wheel b by any of the well known methods. A sheath may be formed
upon, or attached to said tyre in the usual manner. The projections dd' form two
shoulders, and may be made curvilinear, as shewn by Figures 1 and 2, or otherwise
as may be necessary to fulfil the conditions of each case of adaptation. When the
wheel so fitted is in a vertical position as shewn by Figure 1, the projections or
shoulders d d are clear of the ground, but in turning sharply, or in rounding a curve
the angularity of the wheel due to turning causes one of the shoulders d or d¹ to
bear upon the track as shewn by Figure 2, thus presenting a double surface which
precludes any tendency to slipping or skidding. The under surfaces of the aforesaid
shoulders d d may or may not be serrated to increase adhesion.
Our invention is also applicable to other than inflated tyres, and we may
construct solid or cored tyres of any elastic or resilient material without departing
from the lines thereof, and Figure 3 is a cross section of a solid tyre constructed
with projections or shoulders d d', and Figure 4 is a cross section of a sheath or
covering for inflated or other tyres, which may be attached by eyelets, hooks,
lacing or by other known methods, but which has attached, or formed thereon
two opposite projections or shoulders d d for the purpose herein before stated.
Figure 5 is a cross-sectional view of a hollow tyre similarly provided with
projections or shoulders d d¹ as shewn.
In all these cases the object of our invention is fulfilled, namely, to provide an
auxiliary surface upon each side of the tyre of a wheel, which normally is clear
of the road when the wheel aforesaid is vertical, but when said wheel is in an angular
position as when turning sharply, one of said auxiliary surfaces touches the
track and by its adhesion prevents skidding or slipping.
Having now particularly described and ascertained the nature of our said
invention, and the manner in which the same is to be performed we declare that
what we claim is ;-
First. In a tyre for wheeled vehicles the construction and use of a projection
upon each side thereof as an auxiliary bearing surface when necessary substantially
as and for the purposes herein set forth with reference to the appended drawings.
Second. In a tyre for wheeled vehicles the construction and use of an inflated
tyre a with projections d d' upon each side thereof substantially as herein described
with reference to Figures 1 and 2 of the appended drawings.
Third. In a tyre for wheeled vehicles the construction and use of a solid annular
ring of resilient or elastic material in. combination with two projections d d
Figure 3, substantially as and for the purposes herein set forth with reference to
the drawings.
Fourth. In a tyre for wheeled vehicles the construction and use of a sheath or
covering, with projections d d¹, in combination with solid, hollow, or inflated tyres
substantially as herein described with reference to Figure 4 of the appended
drawings.
