419,202. Card-index cabinets. AAGAARD, B., 9<111>, Nordal Brunsgate, Oslo, Norway. April 27, 1934, No. 12812. [Class 146 (i).] In a card-index cabinet employing a central guide 2 over the front edge 3 of which the cards 7 drop to expose parts of successive cards as the card drawer 6 is advanced relatively to the guide 2, the drawer 6 has, in addition to its horizontal movement, an independent vertical movement so that it can be raised to render the guide 2 ineffective until the drawer is lowered, when the edge 3 is adjacent to the cards it is desired to inspect. The drawer is detachably supported on a carriage 4 by crossed links 8 connected by a spring tending to raise the drawer to its upper position, the carriage being slidably mounted in a housing 1 by means of rearwardly extending runners 5 as usual. A pivoted catch 16<a> is provided on the front of the drawer to engage the bottom of the carriage 4, to hold the drawer in its lower position when it is desired to inspect the cards by moving the drawer, either by a direct pull on the drawer front, or by operating, by means of a knob 23, a gear arrangement 22, 26 co-operating with a rack 27 on the casing 1. In order to prevent displacement of the cards as they move over the surface of the guide 2 a ribbon or belt 17 fastened to the carriage 4 at the opposite ends passes along the surface of the guide 2 and over rollers 19, 20, so that it moves with the cards. Slight longitudinal movement of the guide 2 in the casing 1 is allowed under the action of a spring 29 so that the exposing of the cards can take place outside the casing 1.
