PROVISIONAL SPECIFICATION.
Improvements in Tyres for the Wheels of Cycles and other
Vehicles.
JAMES SHAW of 5 Clayton Street, Blackburn, in the County of Lancaster,
Brush Manufacturer and Mill Furnisher, do hereby declare the nature of this
invention to be as follows:-
It is a steel tyre or other metal which is convex on the outside and concave
inside. It fits detached on the circumference of the canvassed air tube, and is
kept in its position by steel flanges, which project from the steel tyre, so as to
clip the sides of the rim of the wheel. The steel tyre does not enclose the
canvassed air tube, but leaves a space of about 1 inch from the steel tyre to the
rim of the wheel. The steel tyre is covered with indiarubber about inch broad
to make it noiseless. The steel tyre prevents puncture, and on account of its
being detached allows or retains perfect resilience.

COMPLETE SPECIFICATION.
Improvements in Tyres for the Wheels of Cycles and other
Vehicles.
I, JAMES SHAW, of 5 Clayton Street Blackburn, in the County of Lancaster,
Brush Manufacturer and Mill Furnisher, 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 improvements in the tyres for wheels of cycles and
other vehicles, the object being to obtain the advantages and resiliency of
pneumatic tyres, and to obviate the liability to puncture and otherwise damage.
The invention consists of a combined pneumatic and metal tyre, so constructed
that the air tube is protected by a detached rubber covered metal im, which is
in contact with the surface of the ground, and the combined air tube and wheel
are free to move or rotate inside and apart from the metal rim. The pneumatic
tyre may be protected by a secondary concentric wheel, the spokes of which are
fixed in the metal rim of the air tube.
Such being the nature and object of my said invention, the following is a
complete description of same, refeience being bad to the accompanying drawings,
in which :-
Fig. 1 is a side elevation of a cycle wheel constructed according to this
invention.
Fig. 2 is a sectional view of the tyre detached.
Fig. 3 is a side elevation of an ordinary pneumatic cycle wheel with my
improvements added thereto.
According to this invention, and referring to Sheet 1 of the annexed drawings,
at 1 is a cycle wheel having an ordinary rim 2, inside which is received a canvas
covered air tube 3. Around the periphery of the air tube 3 is a semi-circular
Price RI

page_text: band or rim of metal 4, preferably steel or aluminium, and this band or rim 4 is
covered on its outer face with a pad or band of rubber 5. The outer rim 4 is
placed over the air tube 3 when the latter is in position on the rim 2, and before it
is fully inflated; and when the air tube is fully inflated, the rim 4 is held
securely in position, so that the rim cannot slip off sideways; but the inner part,
i.e., the wheel 1, rim 2, and tube 3, not being fixed on the rim 4, can move or
rotate in same, and in practise it is found they make more revolutions in a given
distance than the outer rim or tyre 4.
The rubber 5 prevents noise and rattle that would otherwise be caused by the
rim or tyre 4 coming into contact with the ground, whilst the rim or tyre 4
protects the air tube 3, and prevents its being punctured or cut when riding. It
will be seen by Fig. 2 that the air tube 3 is not entirely enclosed by the rim 2 and
rim or tyre 4, but that a space is left between the two. This allows the air
tube 3 to be compressed when riding, so that the tyre retains the resiliency of
the ordinary pneumatic tyre without its liability to be punctured.
If thought desirable or necessary, metal clips 6 (see Fig. 1) may be fixed to the
rim or tyre 4, to assist in maintaining it in position, such clips 6 being passed
round or partly round the rim 2.
In Fig. 3 the inner wheel is made in the manner above described, but the metal
rim or tyre 4 is not covered with rubber, but has spokes 7 fixed to it, and these
spokes carry an ordinary rim 8 with a solid rubber tyre. This wheel is thus a
solid tyred wheel with a smaller concentric pneumatic wheel interposed between it
and the hub 9. The detached rim 4 may with advantage be applied to ordinary
and solid tyred wheels, and in this case would be held in position by flanges, such
as 6, only, or like clipping devices, which clip the ordinary rim 2.
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.) The general construction, arrangement, and combination of parts con-
stituting the improvements in wheels, as and for the purpose herein described,
and substantially as illustrated by Sheet 1 of the annexed drawings.
(2.) The rim 2, air tube 3, and rim or tyre 4, all in combination, as and for the
purpose herein described, and substantially as illustrated by the annexed drawings.
(3.) A wheel, the outer periphery of which is provided with a detached rim or
tyre of metal, as and for the purpose herein described, and substantially as
illustrated by the accompanying drawing.
