in which the transmission ratio is changed by adjustment of the path of movement, the location of the pivot, or the effective length, of an oscillating connecting member

Full Title

Gearings for conveying rotary motion with intermittently-driving members, e.g. with freewheel action > between one of the shafts and an oscillating or reciprocating intermediate member, not rotating with either of the shafts (F16H29/20, F16H29/22 take precedence) > in which the transmission ratio is changed by adjustment of the path of movement, the location of the pivot, or the effective length, of an oscillating connecting member
