PROVISIONAL SPECIFICATION.
A New or Improved Combination Tyre and Rim for Cycles and
other Vehicles.
We, JOSEPH MARSHALL of 39 Parkmount Street, Belfast, Engineer, and
WILLIAM GORDON of 100 Castlereagh Street, Belfast, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a new or improved combination tyre and rim for cycles
and other vehicles.
In carrying out our invention we make the combination tyre and rim, preferably,
in the form of a split tube. The tube, which is or may be made of steel or other
suitable metal is so shaped that its edges overlap and give a spring action.
The tube has or may have a beading round its inner circumference for the
reception of the heads of the spokes.
The metal tube may be made of any suitable strength.

corrugated longitudinally.
As will be seen the tube a which is formed or bent to the proper shape is so made
that the one edge b overlaps and covers the other edge b'. The overlapping edge
or part 6 which forms the inner circumference of the rim is, preferably, made with
a trough or bead c for the reception of the heads of the spokes d.

part or opens out according to the pressure.
A wheel having a combination tyre and rim made as hereinbefore described has
the merits of strength, resiliency, neatness, lightness and durability.
Having now particularly described and ascertained the nature of our said inven-
