Tom. J Martin (sometimes confused with Marshall) was a black inventor who made an improvement to fire hydrants and was issued a patent entitled "Fire Extinguisher." It is nothing like what we call a "fire extinguisher" today, but rather a wet standpipe system for piping pressurized water up to nozzles inside a building. US Patent 125,063 was issued March 26, 1872 to Thomas J. Martin [sic].

If you find any patents under the name of T.J. Marshall, let us know.
