I remember seeing my dad patch tire inner tubes back in the early
60's. The patch was a thin metal "piece" with the patch on one side
and a flammable material on the other. It was clamped over the hole
with the patch side against the inner tube and the flamable material
was ignited with a match. This adhered the patch to the tube and was
called "vulcanizing".
