Abstract: A device for rotating and reciprocating a ram by rotating the ram at the end of each reciprocation. The device includes a pair of supports for the reciprocating means and a pair of supports for the rotating means. Each pair of supports has a set of perpendicular grooves in which a sliding block reciprocates in each groove. The blocks are securely fastened to one another by means of a tie arm. Both the reciprocating means and the rotating means are synchronously driven with a timing belt.
