Abstract: There is disclosed a mechanically driven impact rock fracturing mechanism having a rotary eccentric shaft drive. An impact member in the form of a ring is rotatably mounted on the eccentric shaft and driven in an orbital path to intermittently engage a fracturing shank. Means are provided including a reaction ring to constrain the ring impact member to rotate with respect to the eccentric shaft.
