PROVISIONAL SPECIFICATION.
Improvements in and relating to the Rims of Wheels for Cycles and
other Road Vehicles.
We JAMES WHITEHEAD of Caledon Co. Tyrone Ireland, Shade Blender,
and JOHN GRAHAM of Caledon, Co. Tyrone Ireland Engineer, do hereby
declare the nature of this invention to be as follows:-
Our invention consists of segments placed round the cycle wheel, each segment
resting on two or more springs One end of each spring is attached to inner rin,
and the other end of spring is attached to a segment. Each segment is intact, with
a clearance of in. between the segment to allow for compression; the segments
are grooved on the one side, to receive a solid indiarubber tyre. The whole forms
a wheel, giving a cushion, to the ordinary solid tyre.

Improvements in and relating to the Rims of Wheels for Cycles and
other Road Vehicles.
We, JAMES WHITEHEAD, Shade Blender, and JOHN GRAHAM, Engineer, both
of Caledon Co. Tyrone Ireland, 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 :-
Consists of metallic rim in segments placed around the cycle wheel, or inner rim
each segment resting on two or more springs the springs being attached to the
inner rim or cycle wheel proper the ends of springs being attached to segments
each segment is intact with a clearance of of an inch to allow for compression
the segments are grooved on the top side to receive the solid indiarubber tyre. The
whole forming a wheel, giving a cushion to the ordinary solid tyre.
In order that our invention may be fully understood we now refer to the annexed
drawings in which :-
Figure 1 is a sectional side elevation of my invention.
Figure 2 section through same.
a is the inner metallic rim to which the springs bare attached at g. The ends of
these springs bare attached at f to the metallic segments c which form the outer or
secondary rim and upon which the rubber or such like tyre d is carried.
e is a tongue or strip depending from the tyre d between the ends of the metallic
segments.c thus allowing for compression when the wheel is in operation.
The metallic sections or segments c allow of a certain amount of play thus reducing
the shock or jar when riding owing to the action of the springs b, bearing upon and
exerting pressure between the outer or secondary metallic segmental rim c. and the
inuer metallic rim a and acting as buffers.

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 that what I
claim 18:
In tyres for bicycles, tricycles and the like, an outer or secondary metallic rim
formed in segments, said outer or secondary metallic segmental rim carrying the
rubber or such like tyre having tongues projecting between the ends of said
segments, springs attached to said segments and to an inner metallic rim substan-
tially as described and illustrated.
