Abstract
A lift conveyor in the form of an endless chain is mounted on a vertically extending frame and provides a down-travel side and an up-travel side. Fastened to the chain is a progression of evenly spaced shelves for reception of articles to be loaded on and discharged from the conveyor. Each shelf has opposite relatively flat low friction faces for reception of articles so that on the down-travel side of the chain one of the surfaces receives, carries and discharges articles in one direction whereas on the up-travel side it is the opposite face which receives, carries and discharges articles, and in the opposite direction. Each shelf, moreover, has a laterally tilted mounting on the chain so that articles slide by gravity action onto and off the shelf. Removable chocks are used to keep the articles from sliding off the shelf during travel and until the chock is removed at the time of discharge.
