Modular parts supply rack

A modular parts supply rack for supplying a plurality of containers filled with small parts from a loading end to a delivery end for use by vehicle assembly line operators and for return of empty nested containers from the delivery end to the loading end, the rack comprising a pair of upstanding spaced apart side walls each having a loading end and a delivery end, at least three vertically spaced apart loading end support bars extending between said loading ends of the side walls, at least three delivery end support bars extending between said delivery ends of the side walls, detachable fastening means securing each end of each support bar to its respective side wall, each loading end support bar being paired with the delivery end support bar occupying the same vertical sequential position, the lowermost loading end support bar being at substantially the same vertical level as the lowermost delivery end support bar, the loading end support bar of each of the remaining pairs of support bars being at a higher vertical level than its paired delivery end support bar, the lowermost loading end support bar and the delivery end support bars of said remaining pairs having a generally circular cross-section, a plurality of side-by-side slide members extending between each set of paired support bars, the lowermost slide members extending substantially horizontally for manual return of empty nested containers from the delivery end to the loading end, the remaining slide members being angled downwardly from the loading end support bars to the delivery end support bars for gravity feed of filled containers from the loading end to the delivery end, each slide member including a generally C-shaped mounting bracket structure at each end thereof in detachable engagement with the paired support bars between which the slide member extends, each C-shaped bracket structure having an open mouth, the mouth of the C-shaped bracket structure engaging the support bars which have a generally circular cross-section facing towards the opposite end of the rack with said bracket received on said support bar, the mouth of the other C-shaped bracket structure facing downwardly with said bracket received on the other support bar of the pair, whereby the slide members each are mountable on a pair of support bars by first hooking the C-shaped bracket structure having its mouth facing towards the opposite end of the rack onto the support bar having a generally circular cross-section with the other C-shaped bracket positioned above the other support bar of the pair and then pivoting the slide member downwardly using said hooked support bar as a pivot to engage the other C-shaped bracket with the other support bar of the pair.
