TYPEWRI'IING Application led July 25,

This invention relates toimprovements in bookkeeping devices,'attachablefor use upon the carriage ofan Underwood standard bookkeeping machine. In such machines entries are made on individual cards or memorandum-sheets, and copies of 'such entries are also kept or made upon proof or record'sheets, as usual. A single ventry is made at any particulartime upon each -memorandum-sheet, while the proof or recordfs'heet is retained in the machine and thereafter all the entries are ymade thereon in sequence until the sheet is full.

One of the lobjects of the present invention is to provid-e a simple, efficient and in` expensive attachment for the type of the aforementioned machine vwhich will effectivelyposition relatively to the rotatable platen of kthe 'machine and longitudinallyY thereof, a typewriter-ribbon which is auxiliary to the usual and main typewriterribbon found in such machine, and in such a manner that thc auxiliary-ribbon is suitably divided into two stretches, one of which is positionably adjacent the printing line ofr the machine, and the other of which is arranged out-of longitudinal alignment so as tobegspaced` vertically from the other stretch and `fromsaid printing line.

This expedient `finds particular application in'all cases where it is desirable tov maintain in proper feeding relation, upon the platen of a typewriting machine, a plurality of sheets; saytwo sheets, one overlapping the other andfbeing of a greater width in conjunction therewith, so as to'leave a margin upon `the wid-er sheet. This arrangement of sheets is serviceable toV allow inscriptions to be typed, line by line, upon the relatively narrower sheet, so'as to assure, through the medium of carbon-sheets, or the-like. that those same impressions be produced simultaneously upon the wider sheet; and without shifting one sheet with respect to the other sheet` and while the platen .and carriage continue to make their rectilinear traverse, it is possible to type inscriptions upon the margin of the wider sheet which flanks the narrower sheet, so that these inscriptions may be in line with the-line of inscriptions already typed upon thenarrower sheet, while the carriage and platen are finishing the same traverse across the machine. 1 Y Y y vThe present invention interleaves between 1924. serial' No.y 72eme'. y

the twoy sheets, notv carbon-sheets, but a typewriter-ribbon which extends completely across the longitudinal axis of the platen, projecting beyondthe effectivel width of the narrower sheet and* extending completely across the margin of the wider-sheet by reason ofthe manner in which thev two stretches of this typew'riter-ribbon, already Y explained, are arranged in vertically spaced'- apart relation. It will readily be yseeny that one of these stretches is v allotted to the' narrower lsheet extending'completely across the same, and the other stretch of the same ribbon is allotted exclusively to they marginal portion of the wider sheet, so 'as -to allow the first stretch to belocated at the printing line of the machine andthe other stretch in a position spaced away therefrom, thereby exposing to View of the typistV any inscriptions that may have been typed` upon the marginalportion; ofthe wider. sheet which are located alsoattheprinting line of the machine. It will be understoodthat the main typewriter-ribbon is arranged .so y

as to always come into yprinting-line position, sothat upon the impinging of the usual type-bar therewith at all points upon .its surface co-extensively with thefxfull length of the platen impressions are made at the printing linev across the narrower sheet, which are reproduced, owing to the Y impinging of the same type-bars with the auxiliary ribbon, upon the wider sheet and impressionsv are also -produced, directly, through the'main ribbon, upon the marginal portion of the Iwider sheet at the printing line (as contradistinguished from being reproduced), because in this region the main ribbon does not overlife and is'not-in `longi-V controlled, in operation, by the `line-spacing A y16 of said frame.

mechanism for urging the auxiliary ribbon along in movable relation with respect to the fixed point of engagement of each typebar relatively to the traveling platen. By

means of the present invention any portion of the length of the auxiliary ribbon may be instantly offsetwith relation to another portion within the Zone of the printing operation, so that, while one portionextends along the printing line, the other portion is spaced therebeyond;"likewise itis possible'to dispose and position a given length of the auxiliaryribbon so that it extends completely across the length of the platen, and is locate-d at the printing line or beyondpthe printing line, as exigencies may dictate, and when it is desired'to shift, insert or remove either or both of the sheets held against the platen of the machine, the present invention is arranged to be manually lifted with its auxiliary ribbon out of contact with the sheets, so as to permit this action to take placeconveniently.

Other features and advantages will hereinafter appear.

Referring to the drawings which are merely illustrative of the present invention, 10 and 11 designate the side members or pieces of the usual platen-frame in which is journaled the platen-shaft 13 carrying the `platen 12 which may be rotated by the usual hand-wheel 14; or other means associated with the line-spacing or ratchet-wheel 15. i V

,Theprcsent invention includes a suitable frame arranged to be supported so asi to be movable upon the ends of the carriageefraine by means of bracket-.plates 17 and 18 which overlie the side pieces'lO and 11 of the platen-frame alongside of the usual end plates Said bracket-plates have depending side supports or webs 19 and 20, and are also formed at one end with integral lugs 21, which are suitably pivoted on pins 22 carried by ears 23 having flanges v24 secured by fasteners 25' upon theside pieces 10 and 11 of thel platenframeshelf, incidental to typewriting machines, is

The paperin which are trunn'ioned the pintles 32 ofv spools 33 having guide-flangesv 34 and asso ciated in movement operativelyV with a ratchet-wheel 35. Tlierotation of the spools, or either of them, takes place against the tension of pressure plates 36 which are shown in the shape of spring arms 37 pressed yieldingly against the spools by means of adjustable tensioning thuinb-screws 3S.

The auxiliary typewriter-ribbon 39 `is shown extending across the length of the Y platen and beyond the ends thereof, being operatively supported and fed along in zigzag manner relatively to the platen by means new to be described. The spools 33 are located in a plane at right angles to the longitudinal axis of the platen, and in the course of feeding the opposing ends of they auxiliary ribbon off from or onto the spools, it becomes necessary to divert and change the direction of movement of this auxiliary ribbon, so that the intermediate portion thereof may be disposed at right angles with respect to the direction of said spools, and thus occupy a position alongside of tliemain ribbon 28, as shown in the drawings, but inasmuch as the intermediate portion of this ribbon has to be offset to position one stretch` thereof in elevated relation with respect Yto the other stretchthereof, it becomes necessary to change the direction of n'ioveinent of the intermediate portion of this auxiliary ribbon at another peint, between the endso'l the platen, at which point the vribbon takes a vertical direction of movement with respect to the aforementioned' stretch, so that theY moment any point of the auxiliary ribbon 39 leaves either ofthe vspools 33 in its course of movement towards and upon the other spool, it changes its direction; thrice, and in each instance it has impressed thereon a Vribbon directly from the spools 33, and is led therebeyond so as to be turned over another roller 412, trunnioned upon an ear 43. also struck up from the web 19 or 20. Brackets elet are secured by suitable fasteners upon the webs 19 and 2O immediately above the the length of the platen'at the upper' plane thereof. Fixed ribbon-guides ai'e provided in. the shape of plates 50- and 52 which aie disposed substantially perpendicularly withY respect to the bracket-plates 17 and i8, so as to be located and extended across, below Yse and in front of said spools, as shown particularly in Figures l and 2. The guide-plate 50 ismade longer than the guideplateV 52, so as to extend further down below thelatter and both are formed with oppositely-inclining diagonal slots 5l and 53, respectively, one being spaced .below the other, the slot 5l of plate 50 extending down below the slot 53 of the-plate 52. The auxiliary ribbon 39,

after leaving the idlers or rollers 42, passes downwardly into the diagonal slots 51 and 53, undergoing a change in direction diagonally, as at the portions indicated 39, 35), respectively, so that they are permitted to vassumel adistinctly horizontal direction of movement which causes the intermediate portion of this ribbon to move longitudinally and horizontally across the platen.

The movable ribbon-guide has its upper portion arranged preferably in the shape ofl Aa sleeve 5i, slida-bly engaging a rail or track 48 secured by fastenersiett) vlongitudinally of the back `of the bar'i in spaced relation thereto. Depending from'the sleeve 5-1- is aplate 55 extending downwardly to the lowerinost point of the plate 50 and formed with a pair of vertically-separated diagonal slots57 and 58 which extend in the saine di- V rection, so that the upper slot 57 extends in the saine direction and in horizontal alignment with the slot 53, fornied in the plate 52, and so that the lower diagonal slot 58 extends inthe opposite direction with re-A spect to and in horizontal alignment with the diagonal slot 5l formed in the plate 50. The intermediate' portion of the auxiliary ribbon 39, atfthe points where it leaves the slots 51 and 53 inthe plates 50'and 52, extends across the platen, entering one' of thediagonal slots 57 or 58, say slot 57, and movably project-ing therethrough so as to be movable along the fi'ont surface of the guideplate The ribbon 39 is also arranged to 4iiiovably project through the other slot58,

so that this stretch 39h is disposed diagonally with respect to the longitudinal axis of the platen, and moves in a vertical direction at this point, and so that at one side of the pla'e55 the stretch 39 is disposed horizontally, and at the other side .thereof .the stretch 39 also extends horizontally, but is vertically spaced with respect to the stretch 39.

A handle 59 is secured upon the bar i6 by means of which this bar and 'the pivotal frame carrying it may be lifted and swung upon-the Vpivots 22, so that theauxiliary ribbon 39 may be moved out of contact with `the platen l2, and thus provide clearance for -face of the bar lo and spaced inwardly 'from-the adjacent end. of the platen, this stop having a side gage Giallowing one edge of thememorandum-sheet to engageit as to properly space this sheet with respect .to therela'tively widerrecord-sheet A.

As an effective mean; for feeding along the superposed stretches of the auxiliary ribbon 39 so as to progressively presenta fresh surface of said ribbon against the action of vthe type-bars 29, mechanism ispiovided preferably controlled by the line-spacing n'iechanism of thermachine for interiiiiltently unwindin'g the ribbonv oil' one yof thespools andv'inding Vit up onto the other spool. Suitably secured upon' the line-space slide 62 is a bracket-plate 68 secured thereto by means of a fastener (il, which plate (58 has an angular arm 65 which has a lug 66, receiving the pivot-'pin (SS upon which is fulcrunied the pawl 67 having ratchet-engaging point 6,9, this pawl being held yieldably in a horizontal position by means of a spring 70 which is secured iiXedly upon a stud 7l. i

From the foregoing description, it will be seen that the movable ribboi'i-guide-plate 55 is designed so as Ato slide upon the rail i8 lengthwise of the platen, so as to be heldpsta.- tionary at any point relatively thereto by means of the thumb-screw 56. As this plate 55 inoves'it always 'maintains two stretches of the ribbon 39 at' opposite sides thereof in perfect horizontal alignment, ythe distance it has been adjusted with respect 'to either end of the platen determining. the variable length of one of the stretches with respect to the 4other stretch spacedfvertically therefrom,

which latter is illustrated by the inscription Dear sir indicated at I, or this guide-plate may beheldstationary at the other. extreme end oftheV platen, shown diagran'imatically at Figure 6, whereby the stretch 39 of the 'auxiliary ribbon will be heldexactly at the printing line of the machine, allowing two sheets. of con'iparatively ,equall width to receive simultaneously typed impressions, the outer sheet being typed through theinstru- 'mentality of the main ribbon 28, and the other sheet being typed through the instrumentality of the auxiliary ribbon 89 interleaved between thetwo sheets. It will be seen that when the machineis to be used for another kind of work inv which the auxiliary ribbon is not required, said ribbon may Vbon is threaded with its tivo horizontal stretches 39 and 39 in a manner to be'positioned relatively to. so as to be located be hind, the guide. The vertical stretch 391 which joins the tivo horizontal stretches 89 and 39, and which have a relative motion, extends inv liront of the guide, thus avoiding` the rubbing action o'l the ribbon against the Work-sheet. Y

The present invention linde immediate application in the typingot monthly statements concerning;v which a record copy is made oit the same entries Ona memorandumsheet inserted in the platen, such entries being made on the same date in the various Y statements. Such a type ofinaehine is described in Smith Patent No. 1,327,446, dated May 10, 1921, in which 'form ot invention the ribbon-guide may be pern'ianently set in delinite position.

' After the' record-sheet A and memorandum-sheet B are inserted in the position shown in Figure l, with one edge of the memorandumsheet B engagingl the 'side gage 6l, and with its other end spaced ttorivardly 'form the adjacent edge ot the' sheet A, whereby the marginal portion oi `sheet A is visible, the 'following typingv vaction may take place in the preparation oit' monthly statements. Vil-hen the sheet- A has its outer edge A disposed at the printing` line the marginal portion thereoit, which flanks the sheet B. is typed, through the instru-V mentality ot themain ribbon 28, with the name-ef a lirm, say James Smith, as indicated at (It. Previously thereto the ribbonguide is positioned so as to overlap the edge B ot' sheet P, so that the stretch 39 extends completely across the Width oit sheet l atrprinting-line position, while the stretch 32) is held above stretch 39, so as to expose the margin o't' sheet at the printing-line, in which last-nan'ied Zone the inscription J ames Smith 7 is printed, Thetivo sheets A and B are then successively line-spaced, line by line, and when the upper edge E of the sheet B is Yin printing-line position the Vinscription or name ot the lirm John Doe is typed. as indicated at C, at which time the type-bars 29, when the platen is brought to the proper point opposite the margin o Vsheet A, eti-ect the typing', through the medium of the main ribbon 28, the saine name t John Doe upon the margmalportion ot sheet A, as indicated at H, both inscriptions C and H beine', at this time, in horizontal alignment and locatedat the printing line ol the machine. Any number of account entries may be typed along` the same line between inscriptions C and H against the main ribbon 28', so as tio-produce impressions ot these entries upon sheetli, and reproduce the same .impressions through the medium or stretch 39. of ribbon 39 upon the record-sheet A'. such additional'entries heingdesignated broadly F. Similarly the two sheets are moved or `spaced the next line on the platen l2, and now a: date, such as is indicated at in one lineI and E in another line, is typed upon both sheets through the medium' otboth ribbons toajether with inscriptions of entries F. By means ot this arrangement, while the recordsheet n. is held stationary against the platen, the memoraiulumfsheet B may be moved line by line, relatively thereto, may be necessary, so that any particular date and yaccount entries may be Vtyped siniultaneously upon vthe two sheets at any point thereof along,` the printing line of the meehine opposite the nanieot the lirm H, exposing to thevieiv et the typist the margin oi the sheet i held stationary against the platen.r

it may be desirableto provide a. lever or 5 levers Y2, hilcrun'ied upon a' stud 73, Vand carrying a roller or rollers le which engage the sheets A and?) under tension at the upper plane olf the platen, so as to press these sheetsagainst the llat-ter, a vSuitable springer springs .75 applying the tension against the rollers. By means ot this engagement oi theseV rollers, thersheet A is held stationary and againstlslipping,in the paper-shelf 26 by means of the tension rollers lll when the liront and rear pressure rollers To' and Y? are released it'rom Contact Vith the under side ol the platen, While the i sheet B, released by said rollers 76 and 77,-is

removed troni the machine; it is also possible, in this manner, to insert the sheet B without movin` sheet ii, although rollers 75 and T7 are disengaged from the platen. Atteiboth sheets are yproperly mounted in position the proper rollers .76 and 77 re-engage with the platen to hold these sheets in the usual mriner, and then the roller 74 may be disengaged in any suitable. manner (not shown). Since the ribbon-guide-plate 55 is disposed intermediate the ends of the auXiliary ribben, said guide-plate serves as' a means to prevent the ribbon from 'being dragged around the platen with the werke sheets when the platen is reversely rotated.

T`Jariations may be resorted to Within the scope o't the invention, and portions of the improvcn'ients may-be used Without others.

26. A device of the kind described, consisting of a frame composed of a longitudinal rail, side supports arranged at the opposing ends of said rail, ribbon-guides con-l sisting of a pair of plates ixedly secured upon said side supports, one of said plates being of a greater length than the other and projecting tlierebeloiv, each of said plates being formed With diagonal slots inclining in opposite directions, a movable guide-plate having a slidable connection upon said rail kand formed With two spaced-apart diagonal slots iiicliiiing in the same direction, one of said last-nained diagonal slots inclining in the saine direction and in horizontal alignment With the slot in the shorter plate, and the other slot in the movable guide-plate inclining in an opposite direction. With respect W to and arranged in horizontal alignment With the slot of the relatively longer plate, a typewritenribbon movably projecting through .the slot in the shorter platey and through the slot in the movable plate align- 651mg therewith, soas to produce a horizontal stretch spanning these tWo plates, said ribbon also passing through the remaining slot in the movable plate and through the slot in the longer plate, so as to produce another stretch spanning the longer plate and movable plate and arranged parallel and out of longitudinal alignment with Vthe other stretch, and means engaging the free ends of said ribbon for successively feeding along and taking up said' ends so that said stretches may be advanced intermittently.V

27. A device of the lrind described, con sisting of a longitudinal bar, brackets upon which the ends of said bar are mounted, a rail spaced longitudinally alongside of and supported upon said bar, spools truniiioned upon said brackets in a plane at right angles to said bar, guide-plates disposed belovi7 and f in advance of the ends Vof said bar and supported upon said brackets, idlers mounted upon said brackets between said spools and i plates, one of said plates projecting below `the other plate and both platesliaving op-v positely-arranged diagonal slots, a typewriter-ribbon liaving its ends Wound upon said spools engaging said idleis `and mov.- ably protruding through said diagonal slots, nieaais exerting tension against the rotative action of said spools, a ribbon-guide adjustabiy mounted upon said rail and depending liielou said bar, and means carried by the :uljustable ribbon-guide and movably guiding the intermediate portion of said ribbon so as to divide saidribbon into two horizontal stretches, one of which. is movably held at the level of the 'slot in the shorter plate, and theother of Whiclris inovably held at the level of the slot in the longer plate. Y

28. ln a typewriting machine, the combination of a carriage, a platen on said carriage, a ribbon.' on said carriage extending lengthwise of the platen, anda ribbon-'guide on said carriage to cause part of the ribbon to extend along the printing line and part to one side of the printing line.

29. ln a typewriting machine, the Coinbination of a carriage, a platen on said carriage, a ribbon on said carriage extending lengthwise of the plateii,a ribbon-guide on said carriage to cause part of the ribbon to extend along the printing line and part'to one side 'of the printing line, Vand in zigzag fo ination, and means to change the position of the zigzag of the ribbonivitli relation to the platen.

30. in a typewriting machine, the combination of a carriage, a sliiftable device on said carriage, a platen on said carriage, a portion of ribbon extending from one side of said device along said platen to cover the printing line, a portion of ribbon extending from the other side of said device to one side 'of the printing line, and means to change the position of said device to increase l (il) the lengthof one portion of ribbon While the other portion of ribbon is being decreased.

31. In a typevvriting machine, the combination of a carriage, a platen in said carriage, a ribbon on said carriage extending lengthwise of the platen, and a ribbon-guide to cause part ot' the ribbon to extend along lprinting line and part to one side of the -printing line, and means to change the position of the guide to alter the arrangement of the ribbon with respect to the printing line.

In a typevvriting machine, the combination With a carriage and a platen, of a typewriter ribbon extending lengthvviseof said platen in front of the same, a guide for said ribbon at each end of said platen, the

left-hand one of said guides being positioned f at the'printing line of saidl platen, and the other of said guides being positioned above said printing line, and a shifter plate mov- Y able along said platen and engaging said ribbon to cause the stretch of the latter b'etween saidleft-hand guide and said movabley plate to be disposed atthe printing line,

said plate being also arranged to cause the remaining portion of said ribbon to be disposed above said vprinting line and parallel.
