JOHN WHITEHEAD, 42, Anglesea Street, Lozells, Birmingham, Art Metal Worker,'
and JAMES ALFRED CRANE, 43, Villa Road, Handsworth, in the County of Stafford,
Modeller, do hereby declare the nature of this invention to be as follows:
Г
The object of this invention is to prevent side-slipping, suction, and puncturing...
We form the tyre with two parralell bold projections or treads, preferably in the.
form of conical shaped beads which while affording a clear air passage between
them (preventing suction) by ploughing through the mud maintain their hold.
of the solid ground; and being pliable will individually depress when in the act of
turning, so that both the treads still retain their level notwithstanding the cycle.
may be at an angle.
We are quite aware that somewhat similar beads have been introduced on the
sides of the tyre which only act as treads when in the act of turning, and do not
touch the ground when the cycle is in an upright position.
When applying our invention to pneumatic tyres we may fit into the hollow
space between the two treads, a band of metal or other suitable material; and as
the treads are thick and the other parts of the tyre are clear of the ground, the whole
tyre is free from the possibility of puncturing. The treads also being pliable
would allow of the band to be fitted into the interior of tyre, or it may be embedded-
within the rubber itself, without interfering with the resilliance of the tyrė.
For antisuction purposes only, we may form a longitudinal hollow only, without.
the addition of the beads or treads.
If desirable we may attach the treads in the form of a belt on to ordinary tyres.
or may form the tyres with an indentation (dovetailed by preference) into which
the belt, or the two treads seperately may be fitted.
The amount of tyre surface in contact with the ground being allways confined
to the combined width of the treads cannot be increased by pressure or through
partial deflation.

JOHN WHITEHEAD, 42, Anglesea Street, Lozells, Birmingham, Art Metal Worker,
and JAMES ALFRED CRANE, 43, Villa Road, Handsworth, in the Gounty of Stafford,
Modeller, 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 side slipping, suction and puncturing.
We form the tyre with two paralell bold projections or treads, preferably in the
form of conical shaped beads, which while affording a clear air passage between
them (preventing suction) by ploughing through the mud maintain their hold
of the solid ground, and being pliable will individualy depress when in the act of
turning, so that both the treads still ntain their level, notwithstanding the cycle.
may be at an angle.
We are quite aware that somewhat similar beads have been introduced on the
sides of the tyre which only act as treads when in the act of turning, and do not
touch the ground when the cycle is in an upright position.
For antisuction purposes only, we may form a longitudinal hollow, only without
the addition of the beads as treads.
If desirable, we may attach the treads in the form of a belt on to ordinary tyres,
or, may form the tyres with an indentation (dovetailed by preference) into which'
the belt or the two treads seperately may be fitted.
The amount of tyre surface in contact with the ground, being always confined
to the combined width of the treads, cannot be increased by pressure or through
partial deflation.
We may adapt the various forms of our invention to pneumatic, solid "or
cushion tyres.
We will now proceed to describe the accompanying drawings.
Figure 1 represents in section a portion of a tyre. a is the body of the tyre:
bb are the projections or treads.
Figure 2 is a representation of same shewing effect upon the treads when the
wheel is upon an angle, and in use:
Figure 3 represents in section part of a solid tyre. a is the body of tyre. b is
the longitudinal hollow.
Figure 4 represents in section part of a solid tyre. a is the body of tyre. 6 is
the dovetailed belt forming the treads.
Figure 5 represents in section the double tread belt as suitable for attaching to
ordinary tyres, by means of solution or other suitable means.
Figure 6 represents in section part of a solid tyre. a is the body of tyre. b b are
single treads cemented into tyre a.
...
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what we
claim is:―
1st. Forming a tyre with two paralell bold projections to act as treads both
taking a bearing upon the ground simultaneously.
..
with deen longitudinal hollow

page_text: 3rd. Forming a tyre with a recess or recesses to receive a belt or belts with
double or single treads.
4th. Forming a belt with double or single treads.
5th. Attaching belts with double treads to ordinary tyres by any suitable means..
