J. H. Colwell was the U.S. patent examiner in charge of handling patents in USPC 244, the aeronautics classification, as of the 1912 Manual. Source: https://babel.hathitrust.org/cgi/pt?id=iau.31858045028614&view=1up&seq=15&q1=Colwell

He had other categories in 1908, before category 244 existed: https://archive.org/details/manualofclassifi1908unit/page/6/mode/2up

Records of the patents he evaluated are in Kansas City, at the patent archive. Sean Seyer can give advice; it's straightforward to work there and there is a helpful person who brings the archive boxes to you. He had notable back-and-forths with James Martin among others.

The examiner who evaluated the Wright brothers' first submission was W. W. Townsend.
