Abstract: A self-adjusting hand-held ergonomic holder for jackhammer for manual use by an operator in chipping a hardened ground surface along a continuously variable chipping strike angle. The holder includes a rigid main frame with an upper load bearing handle and a cradle receiving a pneumatically powered hammer with a reciprocatable elongated pneumatically controlled bit operatively mounted to one end thereof. A coil spring assembly associated with the cradle dampens vibrations generated by the jackhammer.

Abstract: A self-supporting pneumatic hammer positioner for effortless command and control by an operator of a pneumatic hammer. The positioner comprises a rigid elongated template having a handle at a first end portion thereof, a saddle mount for a pneumatic hammer at a second end portion thereof, and a 3-axes pivotal mount integral to an intermediate section of the elongated template. An articulated boom member is provided, having an inner end portion and an outer end portion, its inner end portion pivotally mounted to the 3-axes pivotal mount. The boom member outer end portion is pivotally mounted about a one-axis mount to a ground anchor base.
