PROVISIONAL SPECIFICATION.
Improvements in Rims of Cycle and other Wheels, and in Pneumatic
Tyres for the same.
I, SHELDON HAROLD STUBBS, of 16 Percival Street, Birch Lane, Longsight,
Manchester, in the County of Lancaster, Engineer, do hereby declare the nature
of this invention to be as follows:-
My invention refers to the wheel rims and tyres of cycles or other vehicles and
my chief object is to form a complete light weight detachable pneumatic tyre.
My improved wheel rim consists of a hollow rim made of tin or other sheet
metal or material formed with turned over lips or edges; these lips which are
preferably turned over toward the spokes of the wheel, but may be turned in the
reverse direction, serve to secure the tyre or outer band in position over a pneumatic
or other tube.
My improved tyre is stiffened at each edge by means of a wire border composed
say of a single length of wire which is first bent in a flat zig-zag form and then.
bent into a continuous hook transversely, the canvas or rubber covering is then
doubled over the wire and first stitched to the back of the continuous hooked wire
and then along the inner edge whereby the canvas is securely fastened to the wire
and cannot get loose so long as the stitching holds. In place of bending the
zig-zag wire into a continuous hook previous to covering it with canvas, the bending
might be done afterwards, but it would be necessary to stitch the canvas to the
back portion of the wire as before mentioned; in both cases the canvas or rubber.
may be cemented in addition to stitching it to the wire.
This improved tyre can be used with my improved hollow rim or with any rim
provided with reversely turned over lips.

COMPLETE SPECIFICATION.
Improvements in Rims of Cycle and other Wheels, and in Pneumatic
Tyres for the same.
I, SHELDON HAROLD STUBBS, of 16 Percival Street, Birch Lane, Longsight,
Manchester, in the County of Lancaster, Engineer, 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 invention refers to the tyres of cycles or other vehicles and my chief object
is to form a complete light weight detachable pneumatic tyre.
My improved tyre is stiffened at each edge by means of a wire border composed
say of a single length of wire which is first bent in a flat zig-zag form and then
bent into a continuous hook transversely, the canvas or rubber covering is then
[Price 8d.].

and then along the inner edge whereby the canvas is securely fastened to the wire
and cannot get loose so long as the stitching holds. In place of bending the
zig-zag wire into a continuous hook previous to covering it with canvas, the bending
might be done afterwards, but it would be necessary to stitch the canvas to the
back portion of the wire as before mentioned; in both cases the canvas or rubber
may be cemented in addition to stitching it to the wire.
This improved tyre can be used with any rim provided with reversely turned
over lips.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Figs. 1 and 2 represent two forms of hollow rims for cycle and other wheels
applicable for the purposes of my invention.
Fig. 3 are two views of a wire border for a cycle tyre composed say of a single
length of wire which is first bent in a flat zig-zag form and then bent into a
continuous hook according to my invention.
Fig. 4 is the outer band of a wheel tyre with the two wire borders placed in
position upon it and Fig. 5 shows the band turned over the wire borders and
secured by stitching and cementing.
Figs. 6 and 7 represent the wheel rims shown in Figs. 1 and 2 with a pneumatic
tube and outer band or tyre all secured by the stiffened edges of the tyres to the
turned over lips.
In Figs. 1 and 2, a a represents two hollow rims for cycle and other wheels made
of tin or other sheet metal or material formed with turned over lips or edges a¹;
these edges serve to secure the tyre or outer band in position over a pneumatic or
other tube to the rim a.
Fig. 3 represents a wire border composed, say, of a single length of wire b bent
in a flat zig-zag form and then bent into a continuous "hook. In Fig. 4 two of
these wire borders bare shown in position on an outer band of canvas cand Fig. 5
shows the canvas c turned back over the edges and stitched at d some of the
stitches passing between the wires b and effectually preventing the canvas getting
locse; the edges of the canvas are cemented down to the other portion of the
canvas.
Figs. 6 and 7 are views of the hollow rims a shown in Figs. 1 and 2, with the
fully inflated pneumatic tube e and outer band c with its rubber covering call
secured together by the turned over edges which are hooked into the lips a'.
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 I am aware
that prior to the date of my application it has been proposed to use wheel rims
having lips or edges turned over as shown in Figures 1 and 2 of the drawings
accompanying this Specification and I make no claim per se to such construction of
rims, but what I claim is :-
1. An improved tyre which has its edges stiffened transversely by zig-zagged
wires and then bent into hook form substantially in the manner herein set forth for
the purposes specified.
2. In combination a tyre or outer band which has its edges stiffened transversely
by zig-zagged wires and a wheel rim with turned over lips forming grooves adapted
to receive the rigid edges of said tyre substantially as specified.
