Abstract: A system for hanging documents on rails includes one or more of the following: (1) a plurality of flexible straps having head portions at the opposite ends thereof for passing through respective spaced openings in both document attachment means and a rigid support bar on the rails; (2) adapters on the rails having horizontal flanges with upward extending lips, and flexible document attachment strips with apertures defining hook portions with downward extending tabs supported by the flanges and interlocked with the lips of the flanges; (3) folded flexible document attachment and hanging strips with upper end portions hanging over the rails where the folded edge flares apart to provide stronger end portions; and (4) a document compactor with means interlocking with apertures formed in the rails or adapters.

Abstract: Document hanging apparatus comprising an elongated strip of plastic material folded along a longitudinal foldline and having apertures provided in the side portions near the foldline, and adhesive document affixing means provided along one edge opposite the fold to engage a document and secure such document between the sides of the strip.

Abstract: .[.A means for filing documents which is particularly adapted for open filing of various file folders, as for example legal size file folders, and wherein the folders are suspended on horizontal rails and freely slidable longitudinally of the rails, the files suspended below the rails being closely adjacent lower surfaces of a plurality of superimposed files and bars support the file folders on the rails slidably longitudinally thereof, the bars being provided with notches or bearings in their lower edges near their opposite ends so that the file folders, together with the bar, may be placed into a position between superimposed files, as for example, by placing one end of the bar underneath a first rail and then lifting the bar up at its far end and lowering it onto a second rail to engage a respective notch with the rail.
