PROVISIONAL SPECIFICATION.
Air-cushioned Tires for Tricycles, Bicycles, and other Common Road
Vehicles.
I, FREDERICK PUGH, of Elim House, Clifton Street, Swindon, Wilts, Noncon-
formist Minister, do hereby declare the nature of this invention to be as follows:-
Spherical air cavities to be separately formed in the substance of the tire in one
or two lines as required: Elastic balls, about two thirds the size of cavities made
solid or hollow to suit weight of vehicle, to be inserted loose in the cavities to
prevent tire from flattening. The tires to be made single or double, with one or
two lines of air cavities, as may be required.
Dated this 30th day of April 1891.
COMPLETE SPECIFICATION.
Air-cushioned Tires for Tricycles, Bicycles, and other Common Road
Vehicles.
I, FREDERICK PUGH of Elim House, Clifton Street, Swindon Wilts, Baptist
Minister 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 :-
Spherical air cavities to be formed in the substance of the rubber tire in one or
two lines as may be required. Elastic balls, about two thirds the size of cavities
to be inserted loose in the same. The balls to be formed solid, or more or less
hollow, to suit weight of machine-and to prevent tire from flattening at point of
contact with road.
The rubber or other elastic substance used in forming the tire to be of a tough
but sufficiently yielding nature, and not liable to crack or unduly harden by atmo-
spheric influence. Balls to be of the same material.
No specific size of tire is set forth in this Specification as the invention is intended
to be adapted to different kinds of velocipedes and common road carriages, and
must be made proportionate to the weight and size of the vehicle to which it is
applied. No scale is therefore given, the accompanying drawings giving only a
general view of the relative proportions of the tire, the air-cavities, and the balls
inserted therein. The air-cavities are to be placed nearer together or further
apart, to be left entirely void, or to have solid or hollow balls inserted as best may
suit the weight of the cycle or carriage. This invention is also intended to be
applied to the making either of single or double tires; one line of air-cavities being,
as shewn in drawing, used for the single, and two lines used for the double tire.
The drawings accompanying this Specification represent cross, longitudinal, and
oblique sections of the single and double tire, and of air-balls as follows, A. is a
longitudinal section of the double tire. B, a cross section of the same.
C is an
oblique section of the double tire, shewing section of air-ball inserted. D is a cross
section of the single tire, having only one line of air cavities.
The tire, whether single or double, to be made in longitudinal halves, the air
balls to be loosely inserted in the cavities, and the halves united, leaving the air-
cavities perfectly air-tight, and the air-balls free to move about in the same.

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 declare what I
claim is
The invention of air-cavities separately formed and placed in the elastic substance
of cycle and carriage wheel tires, with air-balls loosely inserted in the cavities.
And I make this claim irrespective of the precise form, position, number, or size of
the said air-cavities and air-balls.
