ABSTRACT:
The tool attachment for converting rotating into reciprocating motion comprises a hollow traveling body having a radial bore and an axial bore therein. A bearing housing is removably mounted in the radial bore. A ram is movably mounted in the bore's axial bore. The ram has on its outer periphery a single closed groove having a pitch depending on the desired reciprocating stroke of the ram. A roller is rotatably mounted in the bearing housing and has a portion thereof disposed in the groove. Restraining means couple the ram to the machine whereby the ram is restrained against rotation and unrestrained against longitudinal motion upon the rotation of the traveling body by a rotatable member of a machine fixedly coupled to the body.
