  • Patent number: 4184725
    Abstract: The disclosure teaches a book-holding apparatus to be used with a kitchen cabinet and the like. A leaf, to be used as a book-holder, is provided with means for retaining the book on the upper surface of the leaf and means to hold the book open at a desired page. The leaf is enclosed in a box frame having two spaced sides and a back. Means for supporting the leaf within the frame is provided as a slot carried in each side and back of the frame. At the front of the frame the slot expands upwardly and downwardly. A flange extending from a surface of the leaf is adapted to engage a first stop member to limit the forward movement of the leaf relative the frame. When it is thus limited the forward end of the leaf is outward and its weight causes the leaf to rotate about the first stop member. The rotation of the leaf is limited by a second stop member defined by a forward wall in the upward vault of the slot which engages the upper surface of the back end of the leaf as the leaf pivots about the first stop member.
