Abstract

259,592. Cuinier, H. Oct. 8, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Percussive hand tools.- The driving rod 4 and tup 8 of a percussive hammer have an elastic cushion interposed between them. In one embodiment of the invention a spring system 1 seats on a nut 9 secured to the tup, the nut having a guide bush 6 for the driving-rod, which latter carries a pistons 7 at its lower end. A leather washer 10 is interposed between the piston and the nut. In a modification the springs 1 are replaced by superposed hollow plate springs of elliptical cross section. In a further modification the elastic cushion may comprise superposed concave plates riveted together to form closed vessels and provided with non-return valves whereby the vessels may be charged with air &c. under pressure. The driving-rod and tup may each be provided with a piston 13, 13<a>, Fig. 3, working in a cylinder 12 provided with non-return valves e for the supply of air &c. under pressure.
