Improvements in the Construction of Tyres for Carriages, Bicycles,
Tricycles, and other Road Vehicles.
We, NORMAN KNOWLES and WILLIAM PHILIPSON, trading under the style or
Firm of The Mersey Rubber Company, Bank Quay, Warrington in the County of
Lancaster, India-rubber Manufacturers, do hereby declare the nature of our
said invention to be as follows:-
This invention relates to improvements in the construction of tyres for carriages,
bicycles, tricycles, and other road vehicles, and is designed to prevent the bursting
of pneumatic and other tyres inflated by means of air, gas, or liquids under pressure
when travelling over rough and other roads. The pneumatic tyre consists of an
inflatable tube covered with canvas or a canvas tube or other equivalents. Our
improvement consists in providing the outer casing of the inflatable tube with a
perfectly flat india-rubber sole or outer rim of a width equal to or larger than the
greatest diameter or width of the aforesaid outer casing, by which the latter will be
prevented from coming in contact with curb stones and other projections met
with on roads. The flat india-rubber sole or outer rim is secured to the india-
rubber outer casing of the inflatable tyre by india-rubber or other suitable solution.
The outer flat sole is provided internally with one or more bands of aluminium,
steel, or other metallic tapes or bands which pass round the circumference of the
tyre. The metallic tapes or bauds may be enclosed in canvas or other suitable
material before being inserted in the flat sole. In providing the said metallic
tapes in two or more pieces they will allow the flat sole to yield in case the same is:
bent by coming in contact with curb stones and the like.

suitable solution. The outer flat sole is provided internally with one or more
bands of aluminium, which pass round the circumference of the tyre. The
aluminium tapes or bands may be enclosed in canvas or other suitable material
before being inserted in the flat sole. In providing the said tapes or bands in two
or more pieces they will allow the flat sole to yield in case the same is bent by
coming in contact with curb stones and the like.
Fig. 1 is a cross section of a pneumatic tyre with a flat sole containing three
bands or tapes of aluminium, and Fig. 2 a cross section showing one band or tape
of the same metal.
A is the inflatable tube; B the covering of canvas or canvas bag; C the
india-rubber casing or sole, and D the rim of the wheel.
Our invention consists in providing the outer casing or sole C with the flat
india-rubber sole or outer rim E of a width equal to or larger than the greatest
diameter or width of the outer casing C the rim E being provided internally with
one or more bands or tapes G of aluminium, which pass round the circumference
of the tyre. The tapes or bands G may be enclosed in canvas or other suitable
material before being inserted in the outer rim E. The india-rubber sole or
outer rim E is secured to the casing or sole C by means of india-rubber or other
suitable solution.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
In combination with pneumatic tyres for carriages, bicycles, tricycles, and other
road vehicles the use of a flat india-rubber sole or outer rim E of equal width to or
larger than the greatest diameter or width of the outer casing or sole C, the said
india-rubber sole or outer rim E being provided with one or more bands or tapes
of aluminium, substantially as described and for the purpose specified.
