Abstract

1,183,279. Power hammer. H. CORDES. 18 Sept., 1968 [21 Sept., 1967], No. 44439/68. Heading B3H. [Also in Division E1] A power hammer comprises a fluid operated ram 2 and a fluid operated clamping device supplied with fluid from the upper part 8 of the ram cylinder so that the hammer housing 1 is clamped to an object 12 to be driven during the power stroke. The object may be a pile and the clamping device comprise a piston-cylinder assembly 10, 11 and an opposed jaw 17 for solid piles or a double-piston 11, 11<SP>1</SP> cylinder assembly for hollow piles 15. The piston or pistons 11, 11<SP>1</SP> are spring urged into their retracted position. A damping piston (20), (21), Figs. 4 and 5 (not shown), with a throttling orifice (22), (23) is provided either inside the clamping cylinder or in the supply line 9 so that regardless of the position of the clamping piston the clamping piston will only allow a small loss of fluid before the flow to the line 9 is restricted.
