Abstract
In a live roller conveyor wherein friction drive wheels underlie and drive the live rollers, sprockets mounted on the frame drive the friction drive wheels and are themselves driven by a driving chain course running below them. Both the driving and return courses of the chain are supported and guided by the same chain guide member of extruded plastic which is mounted on the frame and includes laterally projecting flanges having shoulder portions which directly support and guide the respective chain courses. The drive mechanism is provided with multiple sheet metal guard members which are mounted in alternately overlapping (shingle) fashion along the conveyor and are constructed with sections which are readily bendable to accommodate curved stretches of the conveyor. This drive mechanism and the guard members are equally useful on straight and curved conveyors and on combinations of straight and curved conveyor sections.
