Abstract: Apparatus for supporting and storing engineering drawings and similar large size paper sheets comprising a plurality of longitudinally aligned ring binder assemblies each of which includes a plurality of rings which can be opened and closed and extended through holes formed in the paper sheets to be supported, an elongated support member connected to and arranged in a supporting relation with the binder assemblies and provision for disposing the support member in a horizontal position with the ring binder assemblies extending downwardly therefrom so that the paper sheets hung on the rings can hang downwardly from the rings. In one form of the invention, the elongated support member consists of a clamp assembly of a type presently used for supporting engineering drawings and the like and in another embodiment of the invention, the elongated support member is secured directly to the binder assemblies and is supported from a suspension hook.
