JOHN BOYD DUNLOP Veterinary Surgeon 50 Gloucester Street Belfast do hereby
declare the nature of this invention to be as follows :-

I JOHN BOYD DUNLOP of 50 Gloucester Street, Belfast, Veterinary Surgeon 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 improvements are devised with a view to afford increased facilities for the
passage of wheeled vehicles-chiefly of the lighter class such for instance as velocipedes,
invalid chairs, ambulances-over roadways and paths, especially, when these latter are
of rough or uneven character, as also to avoid the sinking of the wheels of vehicles
into the ground when travelling over boggy soil or land; and likewise for the tyreing
of wheeled vehicles generally, in all cases where elasticity is requisite and immunity
froin vibration is desired to be secured, and at the same time ensuring increased speed
in travelling owing to the resilient properties of wheel tyres according to my Invention.
In carrying out my Invention, I employ a hollow tube tyre of india rubber, sur-
rounded with cloth canvas or other suitable material adapted to withstand the pressure
of the air introduced and contained within the tube tyre as hereunder mentioned.
The canvas or cloth being covered with rubber or other suitable material to protect it
from wear on the road. Said hollow tube tyre is secured to the wheel felloes-say by
a suitable cement or by other efficient means-and is inflated with air or gas under
pressure. I may use, for the purpose of inflation, any ordinary forcing pump or like
device; the air or gas (as the case may be) under pressure being introduced to the
interior of the hollow tube tyre through a small duct formed in the rim of the wheel
and provided with a non return valve.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare, that what I claim is:
For wheel tyres, the employment of a hollow tube or of hollow tubes of india rubber
inflated with air or gas under pressure substantially as herein set forth.
