Abstract: 379,727. Typewriters &c. KRONSTEIN, I., 48, Cunostrasse, Grunewald, and KASARNOWSKI, L., 7, Joachim-Friedrich- Strasse, Halensee, both in Berlin. May 30, 1931, No. 15904. [Class 100 (iv).] Type-wheel machines; type-carriages; sheetfeeding arrangements ; line-spacing mechanism; column-printing arrangements.-In a book-keeping machine with a stamp-like printing-mechanism and with flat supports for the surfaces to be printed which are displaceable transversely to the direction of the lines, the printing- mechanism is adapted to set previously the entry to be recorded and is displaceable as a whole transversely to the direction of the columns over a plurality of flat surfaces to be printed arranged on a common table top or the like and independently adjustable thereon for enabling the separate surfaces to be brought into a common printing line. The printing- mechanism 30 is mounted on arms 15 overhanging the table 1 whereon the entry sheets 4k, 4a are clamped in slides 3k, 3a, capable of independent movement in the Y-direction, by means of cords 11 and a spring-actuated drum and held in adjusted position by racks 9 engaged by locking-pawls on the slides 3k, 3a. An additional sheet such as a voucher 4b may be held on the slide 3k by a clamp 13. The printing-mechanism 30 contains type-discs 31 arranged in accordance with the columns of the entry sheet, and a check mechanism 32, which displays similar figures to those set up on the mechanism 30, these mechanisms being operated by setting-keys 33, for numerals and the debit and credit signs, in conjunction with operating buttons 34 which couple the separate groups of type-discs with the setting-keys 33, their return to zero being controlled by a lever 27. The casing 30 is supported by a double rail 22<1>, 22<11>, parallel to the entry lines along which it slides upon rollers, the rails being carried by the two spring arms 15, rotatable upon a shaft 17 fixed on bearings to the table 1. The upper rail 22<11> supports a tabulator bar 24 on which a number of stops 25k, 25b, 25a are arranged corresponding to the column spaces of the entry sheets 4a, 4k, and these stops co-operate with a stop-lever 26 on the casing 30 to determine the position of the printing-mechanism. The latter may be moved along the rails mechanically, similar to a typewriter carriage, or a hand-lever 29 may be used, which also serves to release the stop-levers 26, 28, the lever 27 being provided to re-lock the stop 26 after its release by the hand-lever 29 when the carriage is moved to the right. The shaft 17 carrying the shaft 15 and printing- mechanism 30 may be rocked by a lever 20, by a motor or other similar means. In operation, the first four columns are set to the required numbers, using the keys N, D, G, K, and the setting-keys 33 the amount and the debit or credit key. The printing-mechanism 30 is adjusted to the stop 25k and the slides are brought into position for printing, the lines to be printed being opposite the mark 5. Impression is then made, the mechanism swings back and is drawn to the right by the handle 29 into the position determined by the stop 25b. The voucher 4b is clamped in position and a second impression is then made. The final impression is effected similarly, the balance being calculated mentally and entered by hand together with any additional note. The printing-mechanism 30 and the slide 3k are then returned to their initial position and the slide 3a is moved on to the next line, these movements being effected either bv hand or automatically under the control of the arm 15. As the lever 27 passes the stop 25a, the zeroizing of the amounts column and the account-number column takes place, while in passing the stop 25b the entry number progresses by one unit. The printing- mechanism may be fixed to a rocking arm slidable over the surfaces to be printed in the X- direction or it may be displaceable on rails parallel to the X-direction, the rails being mounted on a carriage which is displaceable above the printing surface in the Y-direction running for example on two rails mounted on the right and left hand of the printing surface. Other setting-devices than the keys 33 may be used, such as setting-slides, levers, or the like, coupled in a known manner to an adding- mechanism which stores up the booked amounts. Ink-ribbon mechanism.-The ribbon-operating device comprises two ribbon spools and a ribbon displacing and feed device ; a two-coloured ribbon is mounted in a yielding ribbon frame which is also displaceable in the Y-direction, this movement being effected according as the debit or credit key is actuated. A protecting plate covers that part of the ribbon which lies directly over the clamping lever 13 and a recess 39 is provided in the casing 30 to accommodate this lever.
