    摘要: A vibratory impact hammer including a hammer body assemblage suspended by rubber mounts for reciprocal axial movement in a support frame, the rubber mounts providing guiding and damping action of the assemblage in either direction of axial movement without extraneous friction forces acting thereupon, and a pair of synchronously driven eccentric weights which are arranged to provide vibratory movement of the assemblage.

    摘要: 57 A reversible pneumatic underground piercing toot of the type having a reciprocating striker (18) with the impact of the striker on the front (19) or the rear (21) of the tool being controlled by the longitudinal position of a valve element (31) in the tool. An interengaging pin (42) and slot (43) arrangement in the tool defines the longitudinal position of the valve element (31) which is positively maintained in the selected position by the supplied air pressure. The iongitu- dinal position of the valve element (31) may be changed for reversing the direction of movement of the tool by interrupting the compressed air supply and rotating the air supply hose (27) a small amount in one direction or the other to reposition the pin (42) in the slot (43).
