139,477. Liedstrand, K. E. L. Feb. 21, 1919, [Convention date]. Statistical machines; with several totalizers.- Relates to means for totalling statistics from slotted cards of the kind described in Specifications 101,224 and 126,624, [both in Class 106 (iv), Indicating &c.]. The cards stacked in a holder 2, Fig. 1, are fed forward by a spring- urged piston against a plate 5, which is reciprocated by a connecting-rod 7 so that a ledge on the plate thrusts the end card past a spring-controlled separating pawl 13 into the grip of feedrollers 9, 10. One of these is toothed to engage marginal feed perforations 12, Fig. 5, on the card. The paired slot system described in the Specifications quoted comprises one slot a, the differential value of which is to be added. The card passes through feed-rollers 16, 17 to the adding-machine in which the pin wheels 19 are rotated by their shaft 18 synchronously with the travel of the cards. As the card enters, a special pin 37 laterally displaces a blade spring 23 which presses the side of the pin wheel and allows a lateral stud 34 on the side of the first pin 26, if there is a slot in this position on the card, to enter a circular slot 31 in the spring, the slot being concentric with the shaft 18. If there is no slot in the card, the pin 26 is pushed in radially by the card and its stud engages a cam edge 32 on the blade spring, so that the pin is swept out of operative position. By this means, all pieces from the commencement up to the length of the slot a in the card are effective to actuate through an intermediate wheel 28 the adding-wheel 39, read through an aperture 43, in the casing. In an alternative arrangement the slot in the card throws a clutch 78, 79, Fig. 6, into action between a power shaft 76 and a counter shaft 77, thus adding while a slot passes the tactile lever 83. A cam 93 holds off the lever while the non-additive slot passes. For this apparatus, the card of the form shown in Fig. 7 is employed. The adding-mechanism is, as stated, of the form employed in the Odhner calculating- machine. Transfer mechanism.-A transfer pin 51 engages a lever 50 of the Odhner calculating-machine type which engages a tooth 52 on the pin wheel setting it so as to add on the next denomination. A cam 52<1> re-sets the lever 50. When the next denomination is not laterally adjacent, but totalizing takes place in a vertical arrangement as shown at 57, 58, 59, Fig. 3, a pin 66, Fig. 9, is fitted to a totalizer-carrying slide 53 in order to disable the transfer lever 50 by displacing its contact head (i.e. that for engaging the tooth 52) against a spring 65 which normally holds this pivoted head in active position. Selecting denomination; splitting machine.- The pin wheel has nine teeth 26 and one revolution corresponds to a card. To each data column position on the card, a set comprising a pin wheel 19, and adding set 28, 39 can be positioned, these being carried on separate slides 21, 46, and held in position by pawls 24, 47. When data columns are independent, totalizing is effected by vertical wheels 57, 58, 59 carried on slides 53, and fitted with transfer parts 60, 62, and read through apertures 63. Operation and item counters.-As the card leaves the machine by feed-rollers 67, 68 it operates by lever 71 and pawl 72 an item counter 74.
