Abstract

780,100. Wrenches. DELISO, J. J. April 14, 1955 [April 30, 1954], No. 10821/55. Class 61. A tool for holding and turning a screw having a head with an hexagonal socket therein comprises two or more springy wires 10, 12 shaped complementarily to fit the socket and each having a flat side to contact a like flat side of the other wire, the wires being held together as by a ferrule 14 on the handle 16 and the free ends 22 being slightly sprung apart so that when pressed together and inserted in a socket, they frictionally engage the socket walls. The wires shown each have the cross-section of half a hexagon, the hexagon being slit diametrically either from corner to corner or through the mid-points of opposite sides. In a modification the wires are held together by welding.
