Abstract: 436,391. Statistical machines. REMING- TON RAND, Inc., 465, Washington Street, Buffalo, New York, U.S.A. April 10, 1934, No. 10812. Convention date, April 10, 1933. [Class 100 (iv)] [See also Group XIX] The invention relates to a record-controlled statistical machine and the Specification as open to inspection under Sect. 91 comprises the following subject-matter. Hammer - impression arrangements.- When the card-reading results in a stop 51, Fig. 2, raising and lowering the nought-stop 52, rack 42 moves to the left to meet the raised stop 51, and teeth 48 set the correct type 50 opposite the platen 46 and ink ribbon 47. Immediately a rack 42 commences to move left its pin 169 allows latch 166 to swing its shoulder 171 over bar 168. At the end of its setting movement to the left, the bar 68 rocks a bell-crank to raise the common bar 168 which raises the overhanging latches 166 and releases the corresponding hammers 164, the latter being thrown by springs 165 against the type. A bar 175 relatches the hammers. Types.-Each computing " unit " has a special type bar 318, Fig. 13 (Cancelled), with types +, -, +A, -A, +B, -B denoting addition item, subtraction item, positive or negative total, and positive or negative grandtotal respectively. For addition items, slide 317 is unobstructed and the bottom + type 50 is positioned opposite the paper 46. For subtraction items, the rocking of shaft 98, Fig. 2, by the special card hole raises finger 319, Fig. 13 (Cancelled) into the path of shoulder 323 on slide 317 to position the - type 50. For a positive total from counter " A " rocking of shaft 139, Fig. 13 (Cancelled), raises stop 325 to arrest shoulder 326 on slide 317 and thus position the + A type 50. If the total is negative, the movement to the right of a slide rocks up a bell-crank 339 to obstruct the shoulder 342 and position the -A type. Certain " units " of the machine are without counters and are used for printing letterpress. Each type-sector 348, Fig. 9 (Cancelled), is controlled by teeth 350 and a rack 351 whose heel 358 coacts with the stops in the basket 357. There are thirty types on each type bar, omitting letter V and including numerals 3, 4, 7, 8, 9. Letter U is shaped so that it may also be used for V and letters O, I, Z, S, and G are shaped so that they may also be used for the numbers 0, 1, 2, 5, and 6 respectively. If a single hole in the card column raises one of the stops 7, 6, 5, ... 0, 11, 12 then the heel 358 is arrested to print a certain letter or numeral. If there be also a second " 8," hole in the column the end 360 of the " 8 " stop is forced up past the spreader 362 and moves all the stops 7 ... 12 one-third of a stop-width to the right so that the raised normal stop of the series 7 ... 12 arrests heel 358 earlier, to position a different letter or numeral for printing than if the normal stop alone had been raised. Similarly, if there be a third " 9 " hole in the card column, the end 361 of the " 9 " stop rises to move the normal stops a further third to the right to arrest the heel 358 still earlier. Special " 8 " and " 9 " card holes in addition to one of holes 7 ... 12 may thus be used to cover the selection of the thirty type on bar 348. When bar 68 reaches the end of its travel to the left, it rocks levers 1663 and 1662 to remove latch 1660 from hammer 1640. This subject-matter does not appear in the Specification as accepted.
