Abstract This invention relates to a rotary storage cabinet comprised of an outer stationary housing and an inner rotatable rotor having four sides two of which are positionable to present the contents of the cabinet simultaneously to two opposite openings in the housing. Two other opposite sides of the rotor are positionable to close the openings in the housing. The cabinet is constructed from a plurality of sub-assemblies which are shipped for assembly at the point of use. The basic structure of the unit comprises a base (20), two pilaster frames (10), and a top frame pan (30) each of which is shipped as a sub-assembly. The cabinet includes several features including: the ball bearing mechanism (FIGS. 7-9); spring urged wheel (180) and detent (150) (FIG. 12) stop mechanism; lock mechanism (160) (FIG. 12); welded pilaster frames (10); and a single centrally located rotor frame (50). The unit is modular permitting the use of like "add-on" units (FIGS. 16 and 17).

Claim 1
Independent Claim
186 words
In a rotary storage cabinet having a stationary housing with openings in two opposite sides and a rotor mounted for rotation in said housing and wherein said rotor has four sides with two opposite sides positionable to present the contents of the cabinet to the openings in said housing and said rotor having two other opposite sides positionable to close the openings in said housing, the improvement comprising said rotor having a generally rectangular base, a generally rectangular top frame pan, and an open rectangular upright frame, said frame having a pair of spaced parallel uprights, a first cross piece extending between and secured to said uprights at their bottom ends, and a second cross piece extending between and secured to said uprights at their upper ends, said lower cross piece being releasably secured to said base, said upper cross piece being releasably secured to said upper frame pan, said rotor having only one of said open rectangular frames, and said one open rectangular frame being releasably secured by its cross pieces across the middle of said base and the middle of said top frame pan.
