PROVIDIUNAL SPECIFICATION.
Improvements in Velocipede Tyres.
I ARTHUR PICKARD Engineer 48 Franklin Road Harrogate do hereby declare
the nature of this invention to be as follows:-
My present invention relates to velocipede tyres & is intended to obviate side
slipping.
In the case of an ordinary pneumatic tyre of circular section I provide a flat
strip of canvas webbing, or other similar material, of about the same width as the
diameter of the tyre. Along each side of this strip is attached a cord made of
solid or tubed rubber, cotton, hemp or the like.
The strip is then by means of cement, cords or wires affixed round the
circumference of the tyre & the two ends joined together.
The width of the strip is such that the two cords after being fixed to the tyre
run clear, or almost so, of the ground while the machine is in a perpendicular
position but any variation of that position will bring one or other of the cords in
contact with the ground thus giving the wheel a better grip of the road & preventing
the wheel from slipping sideways.
In constructing new tyres on this principle the cords would be moulded on to
the tyre
a section of the tyre would represent a circle with one projecting cord
on each side, the cords being separated by about one-third of the circumference of
the tyre.
Dated this 20th day of January 1894.

I ARTHUR PICKARD Engineer 48 Franklin Road Harrogate 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 :-
My present invention relates to velocipede tyres and is intended to obviate side
slipping.
In the case of an ordinary pneumatic tyre of circular section, I provide a flat
strip of canvas webbing or other similar material of about the same width as the
diameter of the tyre; along each side of this strip is attached a cord made of solid
or tubed rubber, cotton, hemp or the like.
The strip is then by means of cement cords or wires affixed round the
circumference of the tyre and the two edges joined together.
The width of the strip is such that the cords after being fixed to the tyre, run
clear or almost so of the ground, while the machine is in a perpendicular position,
but any variation from that position will bring one or the other of the cords in
contact with the ground, thus giving the wheel a better grip of the road, and
preventing the wheel from slipping sideways.
In constructing new tyres on this principle the cords would be moulded on the
tyre, and a section of the tyre would represent a circle with one cord on each
side, the cords being separated by about one-third of the circumference of the
tyre.

page_text: I am aware that cords or ridges on the tread of the tyre have already been
employed to prevent side slipping and I lay no claim to such tyres as have these
ridges in contact with the ground while the tyre is compressed by the riders weight,
and the cycle in an upright position.
In the accompanying drawings
Fig. 1. is a cross section of the tyre with the band attached; the cycle is
upright and the tyre compressed by the riders weight, the cords do not touch the
ground.
Fig. 2. represents the same tyre with the cycle laying over at an angle, but one
of the cords is in contact with the ground.
Fig. 3 and Fig. 4 are sections of the band for attaching to ordinary tyres.
Fig. 5. is a cross section of the complete tyre in its normal condition uncompressed
by the riders weight.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1. An attachment for cementing on to tyres, substantially as illustrated and
described; the cords or ridges whereof shall run clear of the ground while the
cycle is upright, and the tyre is compressed by the riders weight.
2. A complete tyre, having cords or ridges moulded upon it, the cords being
sufficiently far apart to run clear of the ground while the cycle is upright, and the
tyre is compressed by the riders weight.
Dated this 28th day of September 1894.
