ABSTRACT:
For a multi-level rack-type conveyor having a multiple series of racks connected end-to-end to form an endless loop supported on a central standard, a rail-and-roller configuration which provides for each series of racks, an upper, inwardly-facing vertical rail surface and a lower, outwardly-facing vertical rail surface having a free upper edge. Each rack is provided with a pair of upper and lower rollers to engage the respective vertical surfaces, the lower roller having a flange adapted to ride on the free upper edge of the lower rail surface to provide vertical support for the rack. The free edge engages in the corner between the flange and the vertical roller surface to enable the flange to roll on the upper edge without slippage which causes friction and consequent noise and wear. The upper rail of one series is made integral with the lower rail of the upwardly-adjacent series by using a L-shaped member whose horizontal leg mounts the upper rail of the lower series and whose vertical leg mounts the lower rail of the upper series. The rear and under surfaces of the L-shaped member are provided with equipment-attaching and rail-attaching retaining grooves extending throughout their length and through the end portions thereof permitting a wide variety of support configurations for the rail and an infinite adjustability for mounting equipment such as sensors, limit switches and the like, along the length of the rail.
