Abstract: The mechanism consists of a crankshaft and connecting rods driving two rods which extend through the full length of the cylinder of the taper. The rods reciprocate 180.degree. out of phase with each other and pass through a piston assembly. Clutch mechanisms in the piston assembly engage when the rods are moving toward the head assembly and do not engage for the opposite motion. As a result the piston assembly advances toward the head assembly an increment of motion each time one of the rods moves in that direction. A mechanism in the piston assembly engages the head end of the cylinder as the piston assembly approaches the head end and prevents the clutches from engaging so that the piston assembly does not jam against the head end of the cylinder. Also, mechanism is provided to disengage both clutches and keep them disengaged so that the piston assembly is free to move as the cylinder is being filled. This mechanism involves rotating the rods to drive cams which engage the clutches to hold them disengaged.
