ACCOUNTEZNG MACHENE.

Application led August 3, 192'?, Serial No. 210,320, and in Germany August 5, 1926.

The present invention relates to anew and improved accounting machine and more particularly to a machine oil the said type in which the leal of books, sheets, etc. to be written upon are removably clamped on a fiat holder or support.

ln bookkeeping` certain words or combinations of words, numbers, or groups ot numbers occur very frequently and the writing' thereof occasions much loss of time.

The main object of the inve is to provide means which simplities the work oit the book keeper to obvia-te clerical errors.

l attain this and other objects by means ot a device which automatically prints words, numbers or certain groups et words and numbers on the sheets or leaves, the blocks stamps or types with the said words, etc., being always ready to be pressed upon the sheets to obvia'te the composing,` ot letter types and the loss of time connected therewith. rlhe. device may be constructed in such a manner that the duplicatingl or maniolding of the entry in the top sheet is possible to `get with hut one impression a number et copies.

The details of the invention are set forth in the following specification andclaimsand are illustrated in the annexed drawing in a diagrammatical manner in wl'iich Fig. l is a sectional elevation of the machine,

Fig. 2 is a cross-section on line aot Fig'. l,

Figs. 3 6 show details of construction.

The machine shown comprises a table l having two guidegrooves 41-2, 42 running` parallel to each other and in which a board 3 of a maniifolding device is slidably arranged. The said manilolding device is known per se and comprises clips or clamps to hold the original entry sheet, the carbon paper and the copy sheet. On the said table l a support 2 having an arm extending over the said board 3, and below the table l and rigidly fixed thereto is an electric motor .5 ot any known construction. The motor 5 drives by means of a worm del and a worm wheel G a vertical shalt joui-nailed in the support 2. On the upper end ol' said vertical shaft 7 a bevel gear 8 is loosely mounted which is in mesh with a bevel gear 33 fixed to a horizontal shaft 13 rotatably mounted in the horizontal extension of support 2. A. disk le which is rigidly fastened to said shaft 13 carries a crank pin l5 which engages a vertical rod Bel slidably mounted 'in the head 4l@ olf support 2. The rod 84: is provided with a collar 85 which supports a printingl device l5. The device l5 com prises a casinglt in which a shalt 2Llis fixed. On the sha-lt 2e a number of disks are arranged and on each disk a ring` 2G is rotatably mounted bearing' on its outer circumference letters, nlnnbeii's or signs which are to be impressed. The rings 26 having angular cross-section are held by the heads ot screws, screwed into the disks 2G. The inner circular 'face ot each ring 26 is provided with notches 418, one cr cach letter, etc., on the outer circmnlference. In a radial boro ot each disk 2G a pin 2? is arranged which stands under the action of a coiled spring 49 which keeps the pin 2T in engagement with one of the notches 48. By applyii'igj sn'l'licient stress on the ring 2G the resistance of the spring 27 may be overcome and 'the ringmay be turned on the disk 26. The pin 27 however will retain the ringr 26 in its position and secure it againstaccidental. .lisplacement- To enable the disk to be turned more easily a handle 29 is fixed thereto. Over disks 25 a cover 30 of sheet metal is placed and lixed to the casing 16 and providcifl with a slot 50 for each disk 25 through which slots 50 the handles 29 project. The cover 30 is provided with letters, numbers, etc., corresponding* to those attached to the rings 26. By adjusting the handle 29 opposite a number on the edge of a slot the said ringl 26 is brought into such a position that the same letter is iinpressed on the sheet by pressing the device l5 downwards. A type-writer ribbon runs over guide rollers 4&0 and guide pieces 5l, the means to shift the ribbon are well known and are not shown in lthe drawings. Between a plate 3G screwed into the body portion of the device 15 and the collar 36 a spring,` 17 is arranged which transmits the pressure from the rod Bel to the said body portion. Above the disks 25, 26 a dial plate 3l is fixed to the trame of the device and provided with devices, such as numbers, dates, weight amounts, order munbers, etc., corresponding to those on the adjacent disks 2G. The handles 29 may be made in different colors to facilitate the The disks 25, 2.6 are pressed on the sheer es of abook the crank pin 45 may be male Working. The shaft 'i' and the bevel gear 8 are connected by a friction clutch 12 of known construction which clutch may be thrown in and out of engagement by a foot lever (not shown in the drawing). To said foot lever a rod l0 is attachee-; the upper end of the rod 10 is linked to one arm of a bell crank lever 11 pivotally mounted on a stud of the support 2. To the second arm of said lever l1 a bolt 37 is linked which projects in th path of an arm 38 on one of the clnteh members. By pressing on the foot lever the bolt 37 is drawn out of the path of arm S8 and the clutch transmits the otation of shrf" 'hat the crank il.

7 to the bevel gear 8 so i5 reclprocates the rod 34.

ribbon not only on the top sheet, but a's on the copy sheet. The foot lever when fie returns the bolt 87 to its initial position and the gear 8 is arrested. To adjustvthe device to Write on thin 'sheets or on the leavfy and an impression is made by means of the adjustable in radial direction on the disk 14. VHheV spring 17 absorbs shocks. Vtt-r each impression the board 2S is shifted exactly for one line to get the impression on consecutive lines of the sheet-,ete The board 3 isr provided With rack 22 With which a spur Wheel 21 is in engagement. rlhe Wheel 21 is keyed to av shaft 53 journa-lled in hearings of the table 1. .i1 set of bevel gears 20 connects shaft 53 with a vertical shaft l1 and a' second pair of bevel gears 19 connects shaft l1 to a shaft 54e on Which a ratchet Wheel 18 is keyed. Arm 38 of clutch 12 forms a paivl cooperating with said Wheel 18. On each turn of the Crank disk 14 the .shafts 54', l1 and 53 make part of full rotation suflicient to advance the board 3 with the sheet or leaf thereon for one line.

The book keeper in Writing the bills on the original sheet uses the printing device, as often as the Words or phrases appear in the entry to be made and he has only to add the additional Words for changing each entry. A. great saving of time is therefore obtained.

That I Wish to secure by U. S. Letters Patent is 1. In a machine of the class described, a table, a standard thereon having a horizontal arm, a vertical shaft revolubly mounted in said standard, a horizontal shaft revolubly mounted in said arm having a crank at the enter end, gears connect: said shafts together, one of said ars bemg fixed to its 'haft and the other being loose on its shaft,

clutch to lock the loose gear to its shaftI t "will, means to rotate said vertical shaft, board mounted slidably on said table and g a rack, a. shaft geared to the vertical shalt and having a pinion engaging said eek, a vertically reciproeatory member mounted in the horizontal arm and engage: by the pin of the crank, and printing mechanism attached to and vertically movable by said vertically reeiprocatory member.

2. A machine as claimed in claim 1 in -which the printing mechanism comprises :L casing, a fixed shaft extendingv across the casing. a plurality of discs free to turn on said shaft, a printing ring revoluble on the periphery of each dise and having internal ratchet. teeth, each of said discs having spring pressen pawls to engage the teeth of the rings and secure. them against casual rotation, and means to ink the printing characters on the outer periphery of said printine' rings.

in Witness whereof I ailix my signature.

EMIL SCHNEIDER.
