Yep I remember that too.
Vulcanization
"An industrial process that strengthens natural rubber. Because it requires great heat, the process was named after the Roman god of fire, Vulcan."

Not sure about car tubes, but the motorcycle tubes were the rage and this was a good *portable* tool. One note though! The rubber content on nowadays tubes is highly suspect now. they seem to be more plasticky. That process works well on a good tube, but not so much on cheaper Asian ones. That is not to say that there are no higher quality available for a price of course.
I generally use the bench wise and 2 pieces of plywood to accomplish the same effect. It happens mostly now when one uses incorrect size tube, either too small in which case the tube is *thinner* or too large and the tube has a *fold* while inflated.

Oh, my...does that bring back memories. I patched many tubes in my younger days. The trick for me was not to pinch the tube when I put the tire back on by beating it with a mallet and a tire tool. Whoever invented the tubeless tire should get a free pass to heaven.

Used for fixing tires back in the olden days, usually a hot patch.

Actually, vulcanizing was the process that Charles Goodyear invented of adding sulphur to the rubber under high heat to strengthen the rubber. The only patches I remember were glued on. Maybe the gunk, sticky or not, was a combination of fuel for the heat and sulphur to strengthen the patch.

As soon as I saw the photos I remembered the smell. Thanks for the memories.
