  • Patent number: 6352162
    Abstract: A book holder system comprising first and second book ends, each bookend having a substantially planar vertical surface for engaging at least one object such as a book, or the like, that is to be held between the bookends. Each bookend has a horizontal leg that underlies the objects to be held between the vertical surfaces. The horizontal legs of the first and second bookends have complimentary-shaped interlocking projections and recesses. The projections permit disengagement of the first bookend from the second bookend only when the first and second bookends are moved in a vertical direction with respect to each other.

  • Patent number: 5441448
    Abstract: A device for counting, storing and stacking coins for filling standard coin wrappers is disclosed. A plurality of coin tubes is clustered in a parallel relationship. Each coin tube is a hollow cylindrical tube and receives and holds coins of a given denomination in a stack. Each tube has a bottom support surface and an open top. Each tube also includes a transverse slot perpendicular to the longitudinal axis of the coin tube. The transverse slot has a transverse bottom edge positioned so that a stack of coins between the bottom support surface of the tube and the transverse bottom edge of the transverse slot fills a standard coin wrapper for that denomination of coin. The transverse slot is dimensioned to allow extra coins stacked above the transverse bottom edge to slide out of the tube through the transverse slot. A plurality of coin keeper clips is insertable within the transverse slots to prevent coins from sliding out of the transverse slots.
