Abstract
Abstract An indexing mechanism for converting reciprocating motion into intermittent rotary or linear motion. Driving elements engage driven elements during each motion of the reciprocating member in either direction to effect intermittent motion of the workpiece in the desired location. The driving elements also include locking means to limit the motion imparted by the reciprocating member and lock the driven elements in place until the reciprocating member moves in the opposite direction. Several different embodiments are disclosed employing the same inventive principles.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
244 words
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.
Claim 2
Dependent Claim
244 words
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.
Claim 3
Dependent Claim
107 words
The indexing device recited in claim 1 wherein said driving lug means comprises first and second driving lugs, said frist driving lug, when said driving member moves in said one direction, engages one of said driven elements and creates a force component urging said relative movement in said first predetermined path, said second driving lug, when said driving member moves in said opposite direction, engages another one of said driven elements and creates a force component urging said relative movement in said first predetermined path, reciprocating motion of said driving member thereby causing intermittent relative motion between said first and second bodies in said first predetermined path.
Claim 4
Dependent Claim
84 words
The indexing device recited in claim 2 wherein relative movement in said first predetermined path pursuant to movement of said driving member in said one direction aligns one of said driven elements with said second driving lug so as to enable said second driving lug to cause relative movement in said first predetermined path when said driving member moves in said opposite direction, said movement of said driving member in said opposite direction aligns another of said driven elements with said first driving lug.
Claim 5
Dependent Claim
94 words
The indexing device recited in claim 1 wherein one of said driving lug means and said driven elements is formed with a driven surface skewed with respect to the direction of movement of said driving means and a stopping surface forming a V-shaped intersection therebetween, the other of said driving lug means and said driven elements being formed to first engage said driven surface upon movement of said driving member and then to engage both said driven surface and said stopping surface at said intersection thereby stopping relative movement in said first predetermined path.
