ABSTRACT An automatic, reciprocating, indexing and picking assembly apparatus wherein a motor-driven reducer mechanism is drivably connected to an indexer mechanism for providing indexed rotation of an assembly dial plate , and to a first cam-actuated oscillator means for pro- viding reciprocation through a first shaft to a first plate carrying retractable slide pick-up units and through an adjustable positive drive means and a second reducer mechanism to a second cam-actuated oscillator means for providing reciprocation through a second shaft to a second plate , the latter being connected through pivotal linkages to the pick-up units on the first plate Relative vertical displacement between the reciprocating first and second plates affects horizontal extension and retraction of the pick-up units , while overall displacement of the first and second plates relative to the indexed assembly dial plate allows for uninterrupted, indexed rotation of the dial plate and for vertical pick-up and placement of component parts . Adjustment of the positive drive means provides for synchronization of the reciprocation of the first and second plates . Stop-block means and lost motion mechanisms are used to con- trol the travel of the pick-up units so as to eliminate the effects of any non-parallel travel of the first and second plates due to normal manufacturing tolerance variations in the oscillators .
