Abstract

1282615 Power hammers VULCAN IRON WORKS Inc 29 Oct 1969 [7 Nov 1968] 53016/69 Heading B3H A pile-driving hammer for use underwater has a stepped cylinder 12 containing a similarlyshaped piston 15 that is alternately raised by steam pressure and allowed to fall on to an axially-movable anvil 17 abutting a ring 22, which engages with a driving cap (not shown) on the pile. A valve 25 controlling supply and discharge of steam through ports 33 has a semirotary element 27 actuated by a cam groove in the piston. As the piston approaches the head 13 of the cylinder it closes venting ports 40 to effect cushioning. A passageway 42 between the ports 40 and relief ports 41 is connected to a steam-outlet passageway 34, the ports 41 serving to prevent cushioning at the lower end of the cylinder and facilitate escape of water leaking past seals 19. Loss of heat is minimized by an endothermic chemical in chambers 50, 51, (52), Fig. 2 (not shown).
