Indexing device

An indexing device comprising:

• a first body member;
• a second body member mounted to said first body member, said first and second body members being movable relative to one another in a first predetermined path;
• a driving member mounted for reciprocal movement relative to said body member in a second predetermined path, said first predetermined path being non-parallel with said second predetermined path;
• means for coupling said driving member to a source of reciprocatory motion;
• driving lug means mounted to said driving member;
• a plurality of driven elements coupled to said second body, said driving lug means engaging said driven elements individually and successively in either direction of reciprocation of said driving member to cause intermittent relative motion in one direction in said first predetermined path;
• and
• stop means cooperative between said driving lug means and said driven elements to stop said relative motion in said first predetermined path during each reciprocating stroke of said driving member, said cooperative action occurring when said driving member approaches the end of its travel in one direction thereby preventing further relative motion of said first body member with respect to said second body member in said first predetermined path until said driving member moves in the opposite direction, whereupon said cooperative action also occurs between said driving lug means and said driven elements to prevent further relative motion in said first predetermined path when said driving member approaches the end of its travel in said opposite direction.
