Abstract

264,049. Wagner, G. E. April 23, 1926. Percussive tools.- In a rotary percussive tool in which a pair of masses 26 are free to move radially in a cylinder 23 or other suitably - shaped actuator which is rapidly rotated within a casing 20, the masses being constrained to follow a trajectory determined by the shape of a cam 25 secured within the casing 20, the cam is given such a configuration that the trajectory of the masses is symmetrical relative to the axis of rotation except in regard to the part where the masses leave the cam to strike the head of the tool holder 26 where the symmetry is approximate only.
