PROVISIONAL SPECIFICATION.
Improvements in Wheels for Velocipedes and other Vehicles.
I JAMES ROBSON, of 32 Queenshead Lane, Handsworth, in the County of
Stafford, Engineer, do hereby declare the nature of this invention to be as
follows:
-
The object of my invention is to soften and ease the motion in velocipedes, cycles,
and other wheeled vehicles, by applying to the wheel rims of such vehicles, tires
made of that kind of india-rubber known as spongy or cellular india-rubber, or of a
mixture of india-rubber and gutta percha, which are formed with a great number
of air or vapour cells throughout their mass.
It can be applied to the wheel rims either as a rope fixed round them, or the
cellular rope can be tightly inserted and cemented into an india-rubber tube and the
tube be attached round the wheel rim as a tire. By this means any large amount
of water or mud is prevented from entering or lodging in the tire, in cases where
the tire becomes accidently cut or holed, and at the same time the elasticity of the
tire is retained intact.
Dated this Twenty-third day of Sentember 1890.

COMPLETE SPECIFICATION.
Improvements in Wheels for Velocipedes and other Vehicles.
I JAMES ROBSON of 34, Queenshead Road, Handsworth, in the County of
Stafford, Mechanical Engineer, 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 my invention is to soften and ease the motion of velocipedes, cycles,
and other wheeled vehicles, by applying to the wheel rims of such vehicles, tires
made of that kind of india-rubber known as spongy or cellular india-rubber, or a
mixture of india-rubber and gutta percha, which is formed with a great number of
air, or vapour, cells throughout their mass.
It can be applied to the wheel rims, either as a rope fixed round them, or the
cellular rope can be tightly inserted and cemented into an india-rubber tube and
the tube be attached round the wheel rim, as a tire. By this means any large
amount of water, or mud, is prevented from entering, or lodging, in the tire, in cases
where the tire becomes accidently cut or holed, and at the same time the elasticity
of the tire is retained intact.
For the purpose of more fully showing how my invention is carried into practice,
reference is to be had to the accompanying drawings, formning part of this
Specification.
Fig. A. represents a cross section of my wheel rim and tire, 1 is the cellular
india-rubber enclosed in an outer india-rubber tube 2, which is cemented, or
otherwise attached to the wheel rim 3, Fig. B. is part of a side view of the wheel
with the rubber tube 2, and rim 3.
Fig. C. is another method wherein the cellular rubber or gutta-percha 1, is only
surrounded on three sides by the outer rubber casing 2, the inner surface being
cemented, or attached to the rim 3 as represented.
Instead of being in one continuous piece the cellular rubber may be in small
pieces, packed in the outer rubber tube.
In some cases I form the cellular core of a sheet of india-rubber having a large

rolled up into a rope form.
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.
1st. The use of sponge india-rubber, either as a rope or in small pieces, and
enclosed in an outer india-rubber tube, or partial casing, to form an elastic tire
when attached to the rims of vehicle wheels, as described herein.

2nd. The use of a cellular rope formed of a sheet of india-rubber, having honey-
comb like cells formed on its surface, and rolled up into a rope form and wholly, or
partially, enclosed in an india-rubber casing, to form an elastic tire when attached
to the rims of vehicle wheels, as described herein.
Dated this Twenty-third day of June 1891.
