Henry F. Phillips

from Wikipedia, the free encyclopedia

Henry F. Phillips (* 1890 ; † 1958 ) was an American businessman from Portland , Oregon , who bought the patent from inventor JP Thompson in 1935 for the type of screw commonly known today as cross or Phillips screw. Phillips modified the invention and won industrial manufacturers to use the screw. The screw type is now widely used around the world in a somewhat improved form and bears his name. After the screw's design was often copied, Phillips lost his patent in 1949.
