An assembly apparatus of the pick-and-place type having an elongated reach and including an intermittent motion drive mechanism having an output crank arm operable to stop at selected locations. A pivot plate assembly is rotatably journalled to the intermittent motion drive mechanism about the output thereof and capable of being drivably oscillated thereabout. A linkage slide assembly is carried by the pivot plate and comprises slide rods which are pivotally connected to the output crank arm of the intermittent motion drive mechanism for transmitting rotational oscillation into linear sliding movement. A cam member driven by the input of the intermittent motion drive mechanism and engages cam followers carried by the pivot plate assembly. Rotation of the cam member drivably oscillates the pivot plate thereby providing rotatable oscillation to the linearly reciprocating slide rods.
