"Vintage Machinery" entry for Weller Electric Corp.
The amateurish patent drawing might mislead you into thinking this is an unimportant patent. But this is the original soldering-gun patent where the soldering tip is also the resistive heating element. The inventor's timing was exquisite: he began manufacturing his invention right at the advent of commercial television which created an enormous demand for electronics manufacture and repair. The inventor's business was enormously successful, made a lot of money, and saved countless hours that would have been spent waiting for the old-style soldering irons to heat up. Weller's invention got the tip to soldering temperature in the time it took to squeeze the trigger and bring the tip to the work.
