Apparatus for co-ordinating indexing movement of a conveyor with pivoting of a kickout arm adjacent the delivery end thereof

Apparatus for driving an endless loop conveyor in indexing fashion and coordinating movement of a kickout arm therewith, said kickout arm being mounted adjacent a delivery end of said conveyor for removing workpieces therefrom, said apparatus comprising:

• a double acting fluid powered cylinder means having first and second simultaneously reciprocable piston rods extending from opposite of the ends of said cylinder, said rods each having the axis thereof lying in the plane of said loop
• means connected to the first of said rods for driving said loop upon movement of said rod in one of the directions of reciprocating movement thereof,
• said kickout arm having an extension for rotating said arm about the pivot axis thereof from a lowered workpiece receiving position adjacent the end of said conveyor to a raised position for removal of said workpiece from the conveyor, and
• means for operatively connecting and disconnecting said kickout arm from the second of said cylinder rods so that reciprocation of said rod will pivot said arm only while the conveyor loop is at rest between the intermittent movements thereof.
