Abstract

A mechanically powered impact breaker apparatus comprising: a housing; an elongated breaker pin mounted to pivot at one end in said housing, for oscillatory movement about said pivot mount and including at the other end a breaker tip; a drive shaft rotatably mounted in said housing and extending essentially parallel to said pin and in the plane of oscillation thereof; said drive shaft including an eccentric rotation support to rotate therewith; and an impact member supported in said housing for application of shock or impact with said pin and including substantially rigid means supported in rotation in said eccentric rotation support, to establish an imperative connection of said impact member with said eccentric support.
