Abstract: 209,408. Shipley, B. M. Jan. 2, 1923, [Convention date]. Type-wheel machines; column-printing arrangements; line-spacing mechanism.-In a cash register adapted for use in banks and similar institutions for printing deposit and withdrawal items and old and new balances upon a filing card and a pass-book as described in Specification 203,762, [Class 106 (i), Calculating &c.], means are provided for facilitating the positioning of the card and book to receive the impression upon the desired line or column. To re-- cord a transaction, the clerk first places the customer's pass-book in the machine by sliding it between lower guides on a transversely-movable table 635, Fig. 3. He then inserts between upper guides the account card, Fig. 8, so that this lies on the book. The table is then slid along. to position the next blank line beneath the type wheels. In order to facilitate this, plunger keys 654, one for each line on the card or book, are arranged in an extension of the table and cooperate with a fixed stop device. The selected key is held depressed by a slotted detent plate 663 and, on the table being slid to the right, the key-stem rides over the first of a. pair of inclined spring-controlled pivoted stops 668 and then comes into contact with the second of these stops which prevents further movement. Similar action occurs if the key depressed should happen to be on the right of the stops, necessitating movement of the table to the left. To absorb shocks due to the collisions between the keys and the stope, the latter are mounted on a slidable plate 648 controlled by a spring 681. The key is released and the table returned to normal position by its spring 673 when the " new balance" has been printed. The movement of the detent plate to effect this release is derived from the rocking of a shaft, occurring in total-taking operations only, an arm on the shaft producing an upward and leftward shift of the plate to free the depressed key. Mechanism as in Specifications 144,538 and 205,451 is employed to eject the card after the first imprint. Hammer-impression arrangements; ink-ribbon mechanism.-The Specification as open to inspection under Sect. 91 (3) (a) also includes the following subject-matter, which does not appear in the Specification as accepted. (1) The amounts and account numbers set up are recorded on a record-strip by an upper set of typewheels mounted on a shaft 424, Fig. 31 (Cancelled), and also together with the date, set by external knobs, on the file card and the customer's pass-book by a lower set of type-wheels on a shaft 425. The amount wheels on each shaft are quadruplicated and the corresponding impression platens are selectively controlled so that the amount may be impressed in any one of four columns on the record surfaces. The means whereby the differential movements are conveyed to the various groups of type-wheels and the selective control of the platens to effect the impressions in the desired columns are described in Specification 223,939. (2) The ink-ribbon 860, Fig. 31 (Cancelled), passes around an ink-supplying roller 861, a tension roller 869 and the tube and type lines. Shields 866, 867 also encase the latter and together with the roller 861 are mounted on a plate held in position by a screw to facilitate the removal of the plate for ribbonchanging purposes. The ink-supplying roller 861 is intermittently rotated to feed the ribbon by means of a cam mechanism, rocking-shaft 800, and slotted arm 882 to drive a ratchet-wheel connected bv a pair of axial prongs with the end of the roller 861 provided with a circular series of holes to receive the prongs.
