This old service station tool is a Shaler vulcanizer, used for patching
tire tubes. The Shaler Company was founded around 1900 and is still
producing automobile products today. This is a larger version, used
primarily in service stations. A more popular, compact style - the five-minute vulcanizer - was promoted for use by motorists. The user would locate the hole in the
tube and clamp a hot (or cold) patch to it. The sulfur in the
patch was ignited with a match, and the heat generated vulcanized the patch
and the tube together.
This model originally sold in red, though
someone decided to paint this one green - even the Bakelite handle. We
prefer to keep things as original as possible, so we removed most of the
green, leaving as much red as possible. For an "after" pic, click here.
