  • Patent number: 4199173
    Abstract: A clipboard with improved sheet holding means includes an elastic band stretched across a flat, rigid board and having opposite ends secured near opposite corners of the board. On the band are spaced solid beads having bores through which the band extends. The beads may be adjustably positioned along the band or their positions may be fixed. Underneath each of the beads is a friction pad or friction surface. A single sheet of a pile of sheet material may be held between the beads and the friction pads. The beads may be shaped and the bores are located so that the beads and band cam upwardly when a sheet is being pulled away from the pile under the elastic band. The beads can be a cubical with rounded edges, ellipsoidal with bores extending across the shorter diameters, or spherical with bores eccentrically located.
