Abstract
530,606. Card index. AAMODT, M. A. H. June 28, 1939, No. 18853. Convention date, June 29, 1938. [Class 146 (i)] In a card index, in which cards contained in a drawer are supported in trays 4, Fig. 1, having pivoted end-walls 5, 6, which fall outwards when a tray is lifted, so that the cards spread out fanwise, the trays are supported in raised position by spring studs 10, which engage over the upper edges of the side-walls of the drawer. Springy double dividing-cards 12, Fig. 2, may be used to spread the cards, or the cards themselves may be of this form. Dividing-plates 13, Fig. 3, may be used, which have outpressed tongues 14, and are slotted to grip a support 15. The bottom of the tray may be formed in curves to facilitate the spreading.
