A storage and selection apparatus for suspended sheets such as drawings characterized by having a sturdy mechanism to assist lifting any selected stack of sheets and by having selection pins which move endwise toward the pins of the selected stack of sheets for sustained accurate alignment of the pins and reliable transfer of sheets from the pins of the selected stack to the selection pins and vice versa. This storage and selection apparatus comprises a cabinet, a pair of parallel guideways secured along opposite sides of the cabinet, and defining between them a storage space for suspended sheets, main rack bars and an elongated carriage including an elongated frame and an auxiliary rack bar extending with the main rack bars transversely of the guideways with their opposite ends displaceable along the guideways respectively; the carriage is above the main rack bars and provided with a lifting mechanism to selectively lift any main rack bar with the stack of sheets thereon, each rack bar is provided with pins to suspend the sheets, and the auxiliary rack bar is displaceable to and fro longitudinally of the guideways to reliably abut the pins thereof in endwise registry against the pins of the lifted main rack bar thereby allowing to transfer the sheets from the pins of the lifted main rack bar to the pins of the auxiliary rack bar and vice versa to insert or remove a sheet or drawing at any position in a stack.
A storage and selection apparatus for suspended sheets and comprising a pair of parallel guideways laterally spaced apart by a storage space for suspended sheets, a carriage extending over said storage space and having opposite sides engaging said guideways and displaceable along the latter, a plurality of main elongated racks extending lengthwise transversely of the guideways, having opposite ends operatively movable on the guideways respectively and having sheet suspending projections outwardly extending from one side of the racks in one longitudinal direction of said guideways, said carriage including a main frame portion and an auxiliary elongated rack extending lengthwise transversely of the guideways and having sheet suspending projections outwardly extending from one side thereof in the opposite longitudinal direction relative to said one longitudinal direction, a lifting mechanism operatively mounted on said main frame portion, selectively engaging one of said main elongated racks, and operatively lifting said one main elongated rack into endwise registry of the sheet suspending projections thereof with said sheet suspending projections of the auxiliary rack, said auxiliary elongated rack being displaceable to and fro longitudinally of said guideways relative to said main frame portion and toward and away relative to abutment of the projections thereof with the projections of said one main elongated rack, and an acutating mechanism operatively mounted on said main frame portion, connected to said auxiliary elongated rack, and operatively displacing the latter toward said abutment of the projections thereof with the projections of said one main elongated rack, whereby suspended sheets may be slided onto the projections of the auxiliary rack from the projections of said one main rack, and vice versa.
