ABSTRACT:
The present invention relates to a variable stroke, impact device comprising a rotating cam impeller which includes an elongated first end portion adaptable for attachment to a rotary drive source and further includes a curved cam surface formed on a second end portion. The rotating cam surface interacts with a curved end portion of an impact tool to reciprocate a wedge-shaped portion of the tool into contact with a work surface. The length of the stroke and the reciprocating speed as well as the impact force are directly related to the force exerted by the operator in pressing the impact device against the work surface.
