Abstract
A positive lock for infinite adjustable stroke alignment mechanism for a mechanical press with an eccentric bushing disposed within a press connection member with a second eccentric member disposed within the eccentric bushing. A rotatable crankshaft is connected to the second eccentric member. A positive lock alignment mechanism is included for aligning the press connection member with the eccentric bushing to prevent rotation therebetween and permitting rotation of the second eccentric member with the eccentric bushing for infinite stroke adjustment whereby rotation of the crankshaft, when the mechanism is activated causes a press stroke adjustment.
