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.

Apparatus for causing oscillating movement of a ram including a reciprocating stroke and rotational movement of the ram near the ends of ram stroke comprising:
- (a) an elongated ram;
- (b) first and second support blocks each containing a pair of perpendicular arranged ways;
- (c) a sliding block mounted for reciprocating sliding movement in each of said ways;
- (d) an elongated tie arm pivotally connecting the sliding blocks of each support block;
- (e) means for synchronously driving said tie arms so as to cause timed reciprocating motion of said sliding blocks, each of said tie arms including spaced means pivotally connecting said tie arm to each of the associated sliding blocks and pivot means positioned between said pivotally connecting means;
- (f) a drive crank associated with each of said tie arms and having eccentrically mounted means rotatably mounted to said pivot means;
- (g) means for synchronously rotating said drive cranks;
- (h) first connecting means associated with one of the sliding blocks of said first support block for causing reciprocating movement of the ram;
- and
- (i) second connecting means associated with one of the sliding blocks of said second support block for causing rotational motion of said ram near the ends of ram reciprocating travel, said second connecting means further comprising
- (i) and elongated toothed rack fixedly secured to said one sliding block,
- (ii) a rotatably mounted spur gear meshingly engaging said rack,
- (iii) an elongated pivotally mounted pinion arm drivingly connected to said spur gear at one end and terminating at its opposite end in pinion gear means,
- (iv) rack gear means mounted for reciprocating motion and meshingly engaging said pinion gear means, and
- (v) sleeve gear means slidingly and rotatably connected to said ram and meshingly engaging said rack gear means,
- whereby reciprocating motion of said one sliding block causes rotational movement of said ram over a portion at least of its reciprocating travel.
