Abstract: A hanger filing device adaptable for horizontal and vertical file orientation includes an integral binder element comprising a pair of longitudinally extending spaced flanges which define an open channel for receiving file material. A hinge pin is disposed within the binder element and extends outwardly of the ends thereof. The flanges include notched extensions for slidably engaging spaced rails of a hanging file rack. The flanges include spaced opposed apertures dimensioned to receive any of a variety of fastening devices for binding file material between the flanges. The hinge pin provides a post support for the vertical disposition of the binder element within an upright file.

Abstract: A holder for the storage, handling, and filing of sound recording magnetic tape cassettes which is an integral tray-shaped frame, includes a support beam disposed along its upper edge and an index bar extends upwardly of the beam and serves as a handle for the holder. A rectangular base or back panel depends from the lower edge of the support beam and side walls extend outwardly of the marginal edges of the base panel. Spaced posts extend upwardly of the base panel and are adapted to engage and prevent rotation of the reels of said cassette. A resilient retaining flange or tab extends from one of the side walls in spaced parallel relationship to the base panel for releasably gripping a cassette. The base panel is provided with an aperture disposed opposite the retainer tab to accommodate therein a raised land portion of the tape cassette.
