Abstract: A conveyor car used in combination with one or more conveyors to transport loads from one conveyor to another includes modular end units, modular conveyor units, a rigid coupling for coupling end units to conveyor units and a hinge coupling for coupling the two conveyor units to each other. The hinge coupling allows the two conveyor units to pivot up and down near the center of the car but provides a rigid coupling to prevent horizontal movement of the conveyor units relative to each other.

Abstract: A profiled upright side support rail for supporting rollers for rotation about transverse axes suitably spaced apart in the longitudinal direction of a conveyor system is generally L-shaped in cross section and is elevated in spaced relationship to a base by leg angles. The rail includes a generally inwardly extending flange and a generally upwardly extending web portion angularly formed with the flange. The web portion of the rail is generally Y-shaped in cross section and includes a side member, at least three planar sections each provided in a different generally vertical plane, an inwardly projecting shoulder section, and an inwardly extending oblique section. An upper section of the web includes a plurality of upwardly opening notches for supporting the rollers, the notches being spaced apart longitudinally along the upper section by distances equal to desired spacing between the transverse axes of the rollers.

Abstract: An accumulating live roller conveyor is power-driven to effect rotation of a plurality of load-carrying rollers and transport loads from roller to roller without gravity assistance and includes apparatus which is specifically designed to permit loads to remain stationary on the load-carrying rollers without interferring with the operation of the conveyor's drive mechanism. The drive mechanism includes an endless conveying member having an upper frictional driving pass and a lower return pass for transporting the loads along the load-carrying rollers through friction contact therewith. A drive/take-up assembly section for an accumulating live conveyor system permits the loads to selectively remain stationary in conveyor zones located at the ends of the conveyor which typically include drive/take-up rollers and a drive motor without interferring with the operation of the drive/take-up rollers or the drive motor.
