Abstract
A shuttle-type conveyor having a plurality of carriages connected to one another, arranged at a predetermined uniform pitch, and reciprocable along a path through the pitch distance, and a stationary rest extending along the conveyor path, each carriage has an independently operable lifting device. In the operation of the conveyor, if articles are deposited irregularly at an intake station on the rest, the independently operable lifting devices can be operated in such a way as to eliminate vacant spaces in the series of articles being advanced along the rest. This is accomplished by operating the lifting devices of the carriage or carriages behind the vacant space while temporarily disabling the lifting devices of the carriage corresponding to the vacant space and the carriage or carriages located ahead of the vacant space.
