PROVISIONAL SPECIFICATION.
Improvements in or relating to Pneumatic Tyres and Rims therefor.
I, GILBERT ROY, of 17, Whitelow Road, Chorlton-cum-Hardy, in the County
of Lancaster, Oil Refiner, do hereby declare the nature of this invention to be as
follows:-
This invention relates to pneumatic tyres the object being to fix the same into
the rims so that they can be readily detached or partly detached for the purpose
of repairs or for other purposes, and the invention is applicable to split tubeless
tyres, or to tyres consisting of a detachable tube and a split cover.
According to my invention I permanently fix one edge of a split tyre or tyre
cover in a suitable grooved metal rim or ring, and I provide a second inner rim
or ring having one flange only and of such a form and size that the first named
rim or ring fits closely over, and can move sideways upon, the ring until fixed
thereon by suitable clamps or locking devices.
The free edge of the split tyre or tyre cover is brought over in arched form
and inserted between the flange on the inner rim or ring and the adjacent flange
of the outer grooved rim or ring, and the two flanges are tightly clamped
together and grip the free edge of the tyre or tyre cover between them. The
inner and outer rims and the tyre or tyre cover will thus form a pneumatic tyre or
a perfect cover for a pneumatic tube.
The spokes are fitted to the inner rim or ring.
Improvements in or relating to Pneumatic Tyres and Rims therefor.
I, GILBERT ROY, of 17, Whitelow Road, Chorlton-cum-Hardy, in the County
of Lancaster, Oil Refiner, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement: -
This invention relates to pneumatic tyres, the object being to fix the same into
the rims so that they can be readily detached or partly detached for the purpose of
repairs or for other purposes, and the invention is applicable to split tubeless
tyres, or to tyres consisting of a detachable tube and a split cover.
According to my invention I fix one edge of a split tyre a or tyre cover a¹,

page_text: shewn at Figs. 1 and 2 on the annexed drawings, in a suitable grooved metal rim
or ring b, and I provide a second inner rim or ring e having one flange only and
of such a form and size that the rim or ring 6 fits closely over, and can move
sideways upon, the ring c until fixed thereon by suitable clamps catches or locking
devices (as seen at din side view Fig. 3).
The free edge of the split tyre a or tyre cover a¹ is brought over in arched
form and inserted between the flange c on the inner rim or ring c and the
adjacent flange 6 of the outer grooved rim or ring b and the two flanges b c
are tightly clamped together by the catches or clamps d or otherwise, and grip
the free edge of the tyre a Fig. 1, or tyre cover a¹ (Fig. 2) between them. The
inner and outer rims b and c and the tyre a or tyre cover a will thus form a
pneumatic tyre, or a perfect cover for a pneumatic tube e as seen at Fig. 2.
The spokes are fitted to the inner rim or ring c.
In case of a tyre cover the fixed edge of the same may be held in the grooved
rim 6 by a wire or otherwise.
In either case the free edge of the tyre or tyre cover is preferably beaded or
thickened at the edge as shewn at Figs. 1 and 2, and the section of the rim 3 or rings
are made to grip such beaded or thickened edge.
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:-
The combination with a grooved rim in which one edge of a split tyre or tyre
cover is fixed with an inner rim having a flange at one side or edge between which
and the corresponding flange of the said grooved rim the second edge of the split
tyre or cover is clamped substantially as herein before described. .
