Abstract
154,336. Brown, G. L., Hubbard, W. S., and Wheeler, A. D. Aug. 27, 1919. Statistical apparatus; sorting cards. - Relates to card-index systems of the kind in which notches in the edges of the cards are placed to co-operate with selective means for locating them, and consists in means for locating a single card of a large number. A cover is provided which may be applied to any one of a number of card boxes, and is fitted with four selector bars 6, Fig. 1, each attached to a pair of racks 4 gearing with a pinion 11 so as to be set according to a scale 15. A series of ten spaces is allotted to each bar 6 as indicated on the templet 18, Fig. 6, which facilitates notching the cards. Thus, for card 7963 say, the selector bars so set, when the cover is applied to the card tray and the whole inverted, will allow only that card to fall and so to be located. For an extensive svstem the card trays may have permanent bars 17, Fig. 4, arranged so that only cards of a particular classification can be placed therein.
