(01. 197-128) j It is known that typewriters or calculating machines comprising a platen are not, suitable for bookkeeping work. In fact, for such oper ations it is necessary tointroduce on the platen, and over the ?rst sheet of paper constituting the journal sheet, several additional independent sheets. The last line of writing on these addi tional sheets must be written to register with the last line of writing on the sheet carried next to ‘the platen, which,‘ is generally the journal sheet. , . the platen and the‘others by crossbars.‘ controlled‘, by tapes and held in a position always parallel1 to thelaxis of .the platen. , , ‘ .- ‘ r This device eliminates‘ the‘ drawbacks men tioned above by the, fact that it has, in addition. to the normal members for keeping a sheeton the platen of the machine, other members for handling the, account forms or other additional 10 sheets. The subject. of the present invention is distinguished from hitherto known devices ‘for But to effect that, it is necessary on a type this kind by the fact that the tapes carrying the writer to free the journal sheet engaged on the platen and to slide along the invoice form or crossbars by their ends, are connected at one end to a tensioning drum which‘ is subjected to the action of a spring, and‘ ‘at ‘the other end ‘to a manipulating drum which is subjected, to the action ‘oflan escapement device, the crossbars being adapted for holdingv the sheets ‘by their balance sheet which is above the journal sheet, . then to adjust the two sheets, until they register correctly. This work is very difficult to do and also tedious, and besides that the carbon paper placed between the sheets dirties the journal 'sheet. 2 chine at least one sheet, of paper is drawn .by upper edge, and a guide or roll passing under the In consequence this Work takes a very 20 rollers or members holding the sheet carried by long time to effect and it is practically impossible the platen, being provided to guide freely‘the to insist on having clean and neat work. In certain cases it is also necessary to introduce over the invoice form a second independent sheet lower ends of the sheets which are carried‘ by the , crossbars. , ‘ The accompanying drawings show diagrammat constituting the statement of account. The last line of writing of this statement must in the same way be made to register with the last lines of Writing on the journal sheet and on the in voice form. This lastoperation is practically impossible without a great loss of time. ically and by way of example one‘ form of em bodiment of the object of the present invention. ‘Fig. 1 is an assembled View in perspective of my apparatus; ‘ , ' , . . Fig. 2 is a side elevation; Fig. 3 is‘ a front elevation; Fig. 4 is a median cross-section; Fig. 5 is a view in perspective with parts re Certain designers have sought to remedy these drawbacks by arranging, above and in front of the platen, guide rollers for each of the inde moved; pendent ‘sheets; These devices are not very practical and if they allow at the very least the introduction and correct placing of one addi _ ‘ ‘ i - Figs. 6, 7 and 8 are views of details, the last two to different scales from the ?rst. ‘ Referring to the drawings, in Fig. 5, the‘mov tiohal independent sheet, they cannot be used to introduce a second additional independent sheet. In fact the guide rollers of this second able part of the carriage of the machine is fitted at each end with aside-‘piece [0 serving as‘ sup port for the various members of the device. ‘Each sheet are necessarily at some distance away 40 side-piece 10 carries, near the platen a stub shaft from the platen, so that it is necessary to pro II on which are freelymounted two rollers I2 vide guides to lead the sheets tangentially to and I3. On each stub shaft also pivoted an the platen at the height of the typing line. Con arm l4 ‘carrying at its ‘free end two rollers I5 and sequently it is necessary to provide a very big [6, as well'as two spring tensioning barrel mem upper margin and it is no longer possible to use bers l1 positioned beside‘ each other and turning sheets of standard size. In known devices of this kind, and in order to avoid the necessity of releasing the rollers holding the journal sheet ‘ on the platen, the additional independent sheets move in guides which direct the sheet to the back 50 of the machine. ' The present invention relates to a device for manipulating the sheets of account forms'in an oi?ce machine such as a typewriter or a. calculat i-ng machine comprising‘a platen, in which ma loosely on a long shaft I8 which serves also as a ‘connecting bar between the free ends of the two arms l4. One end of the spring of the barrel members I1 is ?xed to the shaft [8.’ ‘ I On each of the tensioning -=barre1 members l'l is ?xed one of the ends of the two pairs oftapes I9 and 20 passing respectively over the rollers I3 and I6 as well as l2 and I5, the other end being . connected to control drums~2l and 2‘2-respec tively. Each pair of control drums is rigidly ?xed ‘ 55 2,411,335 '" ' > 7 ' 4 3 For placing the sheet B in position on the de sired line of writing, the crank 3| is operated which, by means of the toothed segment 21 of the pinion 25 moves the operating control drum idly ?xed on a rotating shaft 29 and 39 respective~ 5 2 I, this latter being maintained in the chosen po ly operated by a crank 3| and 32 respectively ar sition by the pawl 4|. The tape l9 winds up on on an individual long rotating shaft 23 and 24 respectively, carrying a toothed pinion 25 and 26 respectively. Each of these \pinions meshes with a toothed segment 21 and 28 respectively rig ranged on the outer, face of the‘ right-hand side; thedrum 2._| against the. action of the spring in piece l0>(Fig. 5-). the barrel l1, so that it always remains taut.

The two sheets pass for correspondence. ‘ " " " freely under the latter in a guide 46. The tapes l9 serve as support for a crossbar 3d Fig. '7 shows diagrammatically and in perspec and the tapes 20 for a crossbar 35. Each cross tive, in what way the sheets A, B and C come to bar carries a slider member 36 (Fig. 1-’) movable lie over each other on the cylinder of the ma longitudinally on it and allowing the sheetof pa-‘ chine. per to be placed at the desired position along the I Once the sheets are put in position, as described above, they are caused to advance simultaneously from one line of writing to the next by means of the spacing lever of the machine with the help of the device shown in Fig. 8. On the other hand each sheet can be displaced by. itself for instance: width of the platen. On the other hand, hold ing or fastening members 31 are provided on slider member 36 for the upper margin of the sheet of paper.
