July 7, 1936 –
John P. Thompson applied for the patent rights on a “Screw” (U.S. Patent 1,908,080) with an innovative “cruciform groove” and a matching “Screw driver” (U.S. Patent 1,908,081) in 1932. In 1933, Thompson’s patents were transfers to a friend of his, Henry F. Phillips, the managing director of the Oregon Copper Company, a mining outfit in eastern Oregon.
Phillips made some improvements on the screw driver and was granted a patent (US patent 2,046,480) on this date.
The rest as they say, is history, therefore I’ve mentioned it. Otherwise, why would you care?
