PROVISIONAL SPECIFICATION.
Improvements in Wheel Tyres.
I, ALFRED ALEXANDER FURST, of 3, St. George's Avenue, Aldermanbury, in
the City of London, Manufacturer's Agent, do hereby declare the nature of this
invention to be as follows:-
This invention relates to further improvements on the invention forming the
subject of my former Application No. 10705 of 1896. In the specification of my
said former application I described a tyre formed of a tube of celluloid, xylonite,
vulcanite, or other similar hard but more or less yielding or resilient material.
In carrying out my present improvements I employ a celluloid tube but in
combination therewith provide a cover of suitable material and between the
lower part of the cover and the tubular celluloid tyre I provide a bag or chamber
of rubber or other suitable material with means for inflating the. same with air.
To apply my tyre to the rim of a wheel the tubular tyre is placed within the
cover and between the tyre and the under part of the cover I place the air bag.
The edges of the cover are. then connected in any suitable manner so as to enclose
both the celluloid tyre and the air bag.
In adapting the complete tyre .thus. formed to the rim of a wheel it is placed on
the rim the air bag being between the tyre and the rim. The air bag is then
inflated and forces the lower part of the cover against the tyre so as to fix the same
in position.
By this combination I obtain a tyre which is very light and which possesses the
advantages of a combined cushion and pueumatic tyre the cushion being protected
from risk of puncture.
I, ALFRED ALEXANDER FURST, of 3, St. George's Avenue, Aldermanbury, in
the City of London, Manufacturer's Agent, 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 :-
This invention relates to a tyre in the construction of which a tube of celluloid,
xylonite, or other suitable hard but more or less yielding or resilient material.
is used.
In carrying out my present invention I employ in combination with the said
celluloid or other tube a cover of suitable material and between the lower part of
the cover and the tubular celluloid tyre I provide a bag or chamber of rubber or
other suitable material with means for inflating the same with air.

page_text: To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure represents a transverse section of a tyre made according to my
invention; and,
Figure 2 a similar view shewing the tyre applied to a wheel rim.
In the drawing a represents an ordinary wheel rim: the tube of celluloid,
xylonite, or other suitable hard but more or less yielding or resilient material
constructed in the ordinary and well known manner; c is the bag or chamber of
rubber or other suitable material capable of being inflated with air in the usual
manner, and d is the cover of suitable material.
To apply my tyre to the rim a of a wheel the tubular tyre b, the internal
diameter of which is by prefereuce slightly smaller than the external diameter of
the flanges of the rim, is placed within the cover d and between the tyre b and the
under part of the cover I place the air bag c. The edges e, e of the cover are then
connected in any suitable manner so as to enclose both the celluloid tyre and the
air bag as shewn in Figure 1.
In adapting the complete tyre thus formed to a wheel rim it is placed on or
sprung over the rim a the air bag c being between the tyre b and the rim a. The
air bag c is then inflated and forces the lower part of the cover d against the rim so
as to fix the tyre in position.
By this combination I obtain a tyre which is very light and which possesses the
advantages of a combined cushion and pneumatic tyre the cushion or air bag being
protected from risk of puncture.
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 :-
1. A tyre for wheels consisting of a tubular ring or hoop of celluloid, xylonite,
or other suitable hard but more or less yielding or resilient material and an
inflatable bag or chamber enclosed within a cover of suitable material, substantially
as described and illustrated in Figure 1 of the accompanying drawing.
2. The combination substantially as hereinbefore described and illustrated in
Figure 2 of the accompanying drawing of a wheel rim with a tyre constructed as
described and claimed in Claim 1.
