PROVISIONAL SPECIFICATION.
Improvements in Cycle and other Wheel Rims.
We, JOHN WILLIAM FULWELL and EDWIN FULWELL, both of 52 Craven
Street, Chapelfields, Coventry, in the County of Warwick, Engineers, do hereby
declare the nature of this invention to be as follows :--
This invention relates to the manner in which we construct cycle and other wheel
rims in a composite form whereby we are enabled to produce a rim possessing great
trength and durability.
In carrying our invention into effect we construct the rim from two strips of
teel or other metal which we roll to a semi-circular or other suitable section to
form a bed for the pneumatic or other tyre to be employed with the wheel. The
sides or edges of the inner strip are rolled over or formed into a beaded or tubular
shape in such a manner that the extreme edges are brought on to the convex side of
the strip. The convex side of the inner strip is then completely enveloped by the
outer strip, the sides or edges of which are similarly rolled over and are curved
around the beading of the inner or uppermost strip, in such a manner that its
extreme edges are brought towards the concave side of the inner strip. The
beaded or curved ends of the outer or under strip are thus caused to embrace the
like ends of the inner or upper strip, but they are so formed and arranged as to
afford no obstruction to the seating of the pneumatic or other tyre on the concave
surface of the rim.
To securely connect together the two strips forming our composite rim, we
solder, braze or otherwise unite them preferably throughout their entire length.
We do not limit the application of our invention to the production of wheel rims
of any particular section, but make such modifications in their form and in their
general construction as may be necessary to suit the requirements of varying
services.

We, JOHN WILLIAM FULWELL, and EDWIN FULWELL, both of 52 Craven
Street, Chapelfields, Coventry, in the County of Warwick, Engineers, 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 the manner in which we construct cycle and other wheel
rims in a composite form, whereby we are enabled to produce a rim possessing great

Figure 1 is a sectional elevation of our improved rim and Figure 2 is a side
elevation of a portion of the same.
Figures 3 and 4 are similar views of the outer portion of our rim, and
Figures 5 and 6 are like views of the inner portion of our rim detached from its
companion or outer portion.
In carrying our invention into effect we construct the rim from two strips of steel
or other metal which we roll to a semi-circular or other suitable section to form a
bed for the pneumatic or other tyre to be employed with the wheel. The sides or
edges of the inner strip A, are rolled over or formed into a beaded or tubular
shape a, in such a manner that the extreme edges are brought on to the convex
side of the strip. The convex side of the inner strip A is then completely enveloped
by the outer strip B, the sides or edges of which are similarly rolled over at b and
are curved round the beading a of the inner or uppermost strip A, in such a manner
that its extreme edges are brought towards the concave side of the inner strip.
The beaded or curved ends of the outer or under strip B are thus caused to
embrace the like ends of the inner or upper strip A, but they are so formed and
arranged as to afford no obstruction to the seating of the pneumatic or other tyre
on the concave surface of the rim.
To securely connect together the two strips forming our composite rim, we
sometimes solder, braze, rivet or otherwise unite or join them together preferably
throughout their entire length.
We do not limit the application of our invention to the production of wheel rims
of any particular section, but make such modifications in their form and in their
general construction as may be necessary to suit the requirements of varying
services and varying shaped tyres.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The construction and arrangement of a wheel rim formed from two separate
strips and having beaded interlocking edges, substantially as and for the purposes
herein before described and as illustrated in the accompanying drawings.
2. In a wheel rim the combination of an inner with an outer strip, one curved to
bed or lie within the other substantially as herein before described.
