Abstract: 519,013. Segregating and sorting statistics. DIXON, E. K. PORTMAN-. June 13, 1938, Nos. 17522/38, 20049 and 20050/39. [Class 106 (i)] Perforated statistical forms, sheets or cards bearing data, are sorted or classified by being constrained to become threaded individually in succession about a common axis normal to them, so that the sheets or cards of identical characteristics form groups in angular positions according to different data, the groups thus sorted in the one operation being thereafter segregated. As shown in Fig. 6, the cards bearing symmetrical perforations are threaded on a rod 4, so as to occupy different angular positions ready for segregating by passing rods through the perforations 3 and removing the rod 4. The cards shown in Fig. 18 have a commonly placed perforation 15 and triangular groups of perforations 16, the angular positions of which vary according to the data on the card. These cards can be sorted manually by spinning about rod 24 until the perforations 16 engage rods 25, or mechanically as shown in Fig. 20 in which the rods 24, 25 are mounted loosely in a stand 19 on a turntable 26 given approximately two revolutions by each operation of treadle 46. A suitably coloured hood 51 secured by bayonet slots 52 or winged nuts is placed over the rods 24, 25. To help in sorting crumpled sheets, weighted pins 73 depending from holes in plate 72 are adapted to press on a stock of sheets threaded on the central rod 24, through lever and Bowden wire mechanism operated by lever 67 which works the treadle 46. The machine may be provided with a hopper in which case the plate 72 and pins 73 are omitted, and it may be driven by a foot-controlled electric motor. The ends of the rods 25 are chamfered, but for high speed sorting, the ends are bent in the direction of rotation.
