ABSTRACT:
A reciprocating indexing mechanism for linear and rotary outputs which has an output member which inherently reaches a zero velocity at each end of a stroke independent of the input velocity and which utilizes an angular input mechanism, commercially available, which has a rotative movement greater than 180.degree. but less than 360.degree.. The resulting mechanism has versatile kinematic characteristics during the stroke with a smaller acceleration discontinuity at the ends of the stroke than comparable harmonic mechanisms.
