Improvements in the Manufacture of Wire Rings suitable for use in
Securing Elastic Tyres on Bicycle and other Wheels.
I, JOHN SHAW of Dale Street, Coventry, in the County of Warwick, Bicycle
Hollow Fork Manufacturer, do hereby declare the nature of this invention to be as
follows:-
:-
In securing pneumatic and other tyres to the felloes of cycle wheels it is usual
to employ wire rings but with such rings as heretofore made much difficulty has
been experienced owing to their liability to give way at the joints, which, according
to one plan, have been made by reducing the thickness of the wire at the ends and
causing the ends to overlap one another and there soldering them.
It has also been attempted to join the ends by means of a butt joint enclosed in a
metal tube, but such joints have not been found to answer owing to the impossibility
of introducing within the tube between it and the ends of the wire the requisite
solder to make an efficient joint.
Now according to my invention the joints are made by inserting the two ends of
the wire into a longitudinally split tube and then introducing into such tube along
the slit or opening thereof the required solder, by which means I have found that
a very strong and thoroughly reliable joint is produced.
Dated this 3rd day of November 1892.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Wire Rings suitable for use in
Securing Elastic Tyres on Bicycle and other Wheels.
I, JOHN SHAW, of Dale Street, Coventry, in the County of Warwick, Bicycle
Hollow Fork Manufacturer, 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 :—
In securing pneumatic and other tyres to the felloes of cycle wheels it is usual
to employ wire rings but with such rings as heretofore made much difficulty has
been experienced owing to their liability to give way at the joints which according
to one plan have been made by reducing the thickness of the wire at the ends and
causing the ends to overlap one another and there soldering them.
It has also been attempted to join the ends by means of a butt joint enclosed in
a metal tube but such joints have not been found to answer owing to the
impossibility of introducing within the tube between it and the ends of the wire the
requisite solder to make an efficient joint.
Now according to my invention the joints are made by inserting the two ends of
the wire into a longitudinal split tube and then introducing into such tube along the
slit or opening thereof the required solder by which means I have found that a very
strong and thoroughly reliable joint is produced.
Referring to the drawings,
Fig. 1 shews in perspective partly in section a joint according to my invention in
which the ends of the wires are reduced in thickness and overlap one another.

page_text: Fig. 2 is a section of the joint shown in Fig. 1 taken in a plane at right angles to
the plane containing the slit or opening in the tube.
Fig. 3 shews in longitudinal section a butt joint according to my invention.
A and A are the two ends of the wire to be joined together. B. is a tube
whose internal diameter equals the diameter of the wire A A¹. This tube may
advantageously be made of steel of the quality known as best pen steel. B' is a
slit or opening from end to end of said tube. The two ends A and A' having been
carefully cleaned are inserted into said tube, taking care that in the case of a butt
joint the ends of the wire meet midway between the ends of the split tube; then
borax dissolved in water is applied through the slit or opening B'; then the tube
is placed on coke the combustion of which is promoted by the use of a blow pipe ;
during this time solder mixed with borax is applied by suitable means such as a
piece of wire along the slit or opening B' of the tube B, and runs in and makes a
thoroughly efficient and reliable joint.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The herein described and illustrated improved manufacture of wire rings suitable
for use in securing elastic tyres on bicycle and other wheels.
