ARTIFICIAL LEG PATENT
February 10, 1863 - U.S. Patent
Dubois D. Parmelee was issued a U.S. patent for an "Improvement in Artificial Legs" using a custom-moulded suction cup to receive the stump (No. 37,637). Atmospheric pressure held the socket in place such that "straps usually employed for this purpose can be dispended with, and at the same time a perfect fit of the bucket is attained." On the underside of the bucket "a small faucet" was open as the stump was forced into the tightly fitting socket. The faucet was then closed, and atmospheric pressure held the bucket in place until air is readmitted through the faucet. It was 90 years before his idea received general acceptance. Parmelee also invented the first key-operated adding machine (Pat. No. 7,074, 5 Feb 1850).
