Abstract
A single tool carrier reciprocatingly driven in opposite directions by a pair of double ended reciprocating pneumatic pistons, one of the pistons driving the carrier through rack and pinion gear means and the other piston driving the carrier through a pin integrally connected to the carrier, mounted vertically on the carrier and engaging the said other piston. Seal rings, preferably of Teflon, are mounted on both ends of both pistons. The pistons operate in opposite directions. One piston is made relatively light so that its weight and the weight of the other shoe are counterbalanced against each other.
