Abstract: A multi-stage Geneva mechanism comprises first and second Geneva mechanisms and a constant speed ratio drive, such as a gear train, interconnected between the Geneva mechanisms. An adjustment mechanism is connected to the gear train to selectively adjust the phase angle between a crank and wheel of the second stage Geneva mechanism, on the output side of the system. Selective change of such phase angle enables the operator to fine-tune the indexing time to accommodate more precisely the requirements of an automated production line.
