Abstract

1353991 Percussive tools VICTOR PRODUCTS (WALLSEND) Ltd 20 July 1971 [10 Feb 1971] 4387/71 ,Heading B4C [Also in Division F1] A percussive tool, e.g. a drill, comprises an anvil 41 forming the tool head and struck by masses 37A, 37B reciprocated by hydraulic pistons 30A, 30B operating 180 degrees ot of phase, the pistons being controlled by a common spool valve 3. A port 47A, 47B in each working cylinder is controlled by the respective piston 30A, 30B to effect valve reversal at the end of each stroke (see also Division F1). Each piston has a lost-motion connection 38, 40 with its respective mass. An abutment 35 limits the piston stroke.
