1934 · SETTLED IN THE INVENTORS LEG
One paragraph, by design: The strongest "first" in Mishawaka's technology record is not this section's to retell: the foundational patent of airless blast cleaning — filed from this city in 1934 by the Wheelabrator company's founder, US 2,077,637 — stands whole in the Inventors leg, with the claim tested there at the strength its carriers earn: the History Museum's account calls the Wheelabrator "the first successful airless blast cleaning method," and the company's own historian, Tony Harris, writing in 1964, dates the introduction of "the first practical airless blast-cleaning" machine to the Depression years; the name the whole world uses for the process is the trade name this city's works coined. It is pointed to here, once, so that this section's ledger of claims is complete — a tested first, settled where the patent record lives, beside this section's untested ones, which are printed above at their carriers' names.
