When was the Phillips head screw invented and why?

The Phillips head screw was invented by an obscure employee from the Ford Motor Company named Alexander Pendrew in 1923. He devised this screw to isolate the manufacture and repair of Ford products. A person was required to Push Hard (PHillips) to install it easily but the design caused removal to be more difficult thereby ensuring that the screw would remain installed even during vibratons caused by driving conditions at the time.I think it was patented in the 1930s. It was invented to provide an "automatic screw-driver" function on assembly lines. When the screw was tightened sufficiently, the bit would start to slip.That is, unlike the TORX screw, the Philips-head was not for the purpose of increasing the torque on screws.Henry F. Phillips formed the Phillips Screw Company in 1934, and after refining the design himself (U.S. Patent #2,046,343, U.S. Patents #2,046,837 to 2,046,840) for the American Screw Company of Providence, Rhode Island, succeeded in getting the design quickly adopted by industry.
