ABSTRACT:
An improved reciprocating ram for an envelope inserter includes a pusher which drives an enclosure from a ram pick-up station to an envelope station. Cycle time has been reduced by providing a ram return path which is beneath the elevation of the pick-up station. Thus, the next enclosure is fed to the pick-up station before the ram has completed its return stroke. The ram mechanism includes a ram carriage which rides along a pair of longitudinal rods. A ram block carrying a ram blade rides with the carriage and is keyed for vertical movement relative to the carriage. The block includes a follower which engages a longitudinal box cam having a latch adjacent its envelope station end. When the ram blade reaches the envelope station, the latch directs the follower to a lower elevation camming surface for the return stroke. The pusher is secured to the ram blade by a leaf spring catch which engages a grating on the undersurface of the blade. The pusher position is adjusted by depressing the leaf spring to release the catch.
