ABSTRACT:
An article conveyor and package aligner comprises a pair of guide members converging from an infeed station to an outfeed station, a conveyor for moving articles toward the outfeed station, and a pair of levers, one connected to each guide member, below the conveyor. The levers are cantilevered, each carrying a latching pin or roller and a notch cooperating with a similar pin and roller and notch on the other lever. The levers lie closely adjacent and cross each other so as to comprise an escapement mechanism which is in either an "at rest" condition, a locked condition or a released condition, depending on the position of a package traveling along the conveyor and the relation of that package to one or both of the guide members. A package contacting one guide member causes locking of the escapement mechanism and thereby of the guide member which is so contacted, forcing the package laterally until it contacts the other guide member. At the time it contacts the second guide member, the package has been properly aligned with the machine to which it is being fed. The second contact releases the escapement mechanism, thereby freeing both guide members and permitting unencumbered passage of the package toward the outfeed station.
