ABSTRACT:
A percussive tool has a percussion mechanism driven by a linkage that combines the simplicity of a connecting rod drive with the compactness of more complex drives. A first member, which may be a crank, drives a second member, which may be a cylinder, mounted for sliding and pivotal movement in a guide. A piston is mounted for reciprocating movement in the cylinder. Rotation of the crank reciprocates the piston causing blows to be imparted to a tool piece. The tool piece is rotated as well as being subjected to percussion.
