PROVISIONAL SPECIFICATION.
Improved Means for Preventing Slipping of Pneumatic Tyres.
I, FRANK THOMPSON SHELMERDINE of No. 27 Tennyson Avenue East Ham
Essex do hereby declare the nature of this invention to be as follows :-
My invention consists of indiarubber bands to be fixed round both tyre and rim
of cycle wheels fastening by clips at the back of the rim.
The bands are moulded so that the thickest part takes the ground, and are
placed on the wheel about 6 ins. apart so preventing side slip, and doing away with
groved covers.
Dated this 20th day of February 1893.

Improved Means for Preventing Slipping of Pneumatic Tyres.
I, FRANK THOMPSON SHELMERDINE 27 Tennyson Avenue, East Ham, Essex,
Marine Superintendent do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention consists of narrow bands made of india rubber or other suitable
material to be fixed round both tyre and rim of pnematic wheels fastened by
clips or hooks at the back of the rim, and held in place by the stretch or tension
of the rubber or other material used. If made of a strong india rubber I have
found 4 inches long by inch wide and inch thick to be the best size for a
wheel having a 2 inch tyre. They may be made larger or smaller to suit tyres of
various sizes. If made of other material the strength and texture of the material
used would determine the difference in size. The bands are moulded or fashioned
so that there is at the centre about one inch of the band thicker or a total thickness
of inch. The ends of the band are made thicker and a hole moulded through
in which to secure the hook or clip, and in order that the hook may not tear out
from the rubber or other material, the hole is lined with canvàs. The hooks or
clips are made of a strong wire and may be made to hook either on to the spokes
or into each other.
The bands are placed on the wheel at intervals of say 5 inches apart, and are
so adjusted that the thick part takes the ground, making when all are in place a
series of ridges or corrugations across the face of the tyre all round the wheel.
In order that my invention may be more readily and easily understood
reference may be had to the accompanying drawings forming part of this
Specification in which
Figure 1 is the band.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I do declare that what I
claim is :-
1st. A band made of india rubber, or other suitable material which may be
fastened round the tyre & rim, made so that it may be readily put on and
taken off.
2nd. Presenting corrugations to the ground which gives the tyre a grip and
prevents side slip.
