ABSTRACT OF THE DISCLOSURE A housing contains a plurality of vertically spaced shelves movable vertically relative to each other upon activation of a fluid pressure piston-cylinder uni t mounted on the housing. Elongated suspension rods depend from the top shelf to support the next two adjacent shelves for relative vertical movement, and each subsequent lower shelf is similarly supported by a shelf above it but separated from it by one intervening shelf. The two top-most shelves also are arranged to be secured together detachably in abutting relationship. The lower end of each suspension rod mounts a rotary disc which supports a pair of upstanding spaced pins arranged in one position of rotary adjustment to abut the underside of a lug extending laterally from the adjacent shelf, and in a second position of rotary adjustment, 90° from the first position, to register with openings in the lug, whereby the associated shelf is lowered from the first position of support a distance substantially equal to the length of the support pins. This support arrange- ment allows the shelves to be adjusted to four different spacings.
