Abstract

515,451. Storing reference books. HEYMANS, R. E. L. June 2, 1938, No. 16540. [Class 52 (i)] In apparatus for storing reference books of the kind in which the book 1 is stored back downwards and raised through a vertical slot 3a for use, the book support 2 extends rearwardly from a vertical carriage 4 having pairs of rollers 4a, 4b adjacent its top and bottom engaging vertical guides 3c. The rollers have their axes at right angles to resist both lateral and longitudinal movement. Flaps 2a hinged to the book support 2 engage curved guides 3d at the sides of the slot to close the book as it is lowered. Counterbalance weights 5 are connected to the book support by a leather thong 5c passing over pulleys 5b and engaging a cross-piece 5e fixed to the book support by a bracket 5d. An external operating knob 6 is fixed to the carriage 4. As shown two or more books are arranged side by side. and interlocking mechanism may be provided to ensure that one book cannot be raised until the other book has been returned to the stored position. Such mechanism may comprise pawls engaging one of the lower rollers of each carriage and released through a Bowden wire connection by a wedge or cam on the other carriage. In a modification the counterweights are omitted and the two carriages are connected together by an endless leather thong passing over pulleys so that as one book is moved up the other moves down. The book supports are connected to the thong by brackets damped to ferrules on the thongs. For detachably securing the book 1 to the book support 2 a rod 7b is provided passing through slotted plates 7e slidable on pins 7d on the support 2 the rod being engaged at its ends by. tension springs 7f. The raising and lowering of the book may be effected by lever mechanism.
