' This invention relates to typewriting machines of thatv class* employing collating mechanism of the general character disclosed in the patent to J. A. B. Smith, No. 1,503,069, ggranted July 29, 1924..,- l v It has been proposed to mount auxiliary ribbons permanently in thev typewritingA machine -for manifoldin purposes, butthis is found to be 10 impracticab e except for a worksheet which is inserted inthe machine onl once for the typing of the` entire sheet. nel of-theobljects of the present invention is to makelit practicableto employ auxiliary interposed x5 ribbons in cases where itis necessary to reinmaclnne every time` sert the sheet. into the that an item is to be typed kinds of bookkeeping or statement work, v,a sheet must be reinserted many times before 80 it is 'iilled up, as only one itemis typed at each insertion. In attempting to employ the usual auxiliary ribbon for'this'purpose, it is found that the sheets become so crooked from Contact with the auxiliary ribbon, by l5 reason of the frequent insertions, as to prohibit the use of such ribbon. Moreover, 'the diiiiculty of inserting asheet betweenthe platlen and the auxiliary ribbon, which, extends along the entire front of the platenA and close thereon. In some lo thereto, is difficult and time-consuming.

One of the objects of the present invenvtion therefore is to overcome this diiiculty and to afford to the operator the use of an interposed ribbon without incurring the aforesaid objections. To this end it has been contrived that no ribbon is mounted in the mchine, and therefore cannot interfere with the manipulation of the sheets or crock the same. The sheets are quickly placed in the machine and collated at desired positions for the manifoldiug of a single-line entry; 'and after the sheets have been' so collated, an inkribbon is dro ped in between the sheets. The ribbon, for t is purpose, is mounted upon a large card or thin stiff frame, which readily slips edgewise into position between the work-sheets. In order that the inserted ribbon shall be readily located at the printing line, there is provided upon the card a locating shoulder or edge, which engages with a use between thel kworksheets for` Vable from one printing ield to the corresponding locating shoulder or edge that is provided upon the typewriting machine, so that it is only necessary to drop in the card far enough for it to engage with the locating shoulders on the typewriting machine, whereupon the item may be typed. Upon completing the typin of the item, the card may be withdrawn, an the work-sheets may also be withdrawn, 'and new sheets insertedand collated, whereupon the same card may be inserted between the new sheets; and soon.` The work thus proceeds with celerity, and the advantage is preserved of making an ink-ribbon copy as distinguished fromv the objectionable carbon-copy.

Another feature is that the inserted rib; bon may be of the bichrome variety, and may therefore make a copy of the same color as the original typing upon the outside sheet; the inserted ribbon being adjustable or shift other, or locatable in either printing eld at will.

For collating the sheets, there is provided a device which clamps each sheet upon a sep-- arate slide; each slide with its sheet being adjustable as a unit independently of the 4other slide and sheet; and this feature of the invention may be employed for other purposes, in machines in which carbons are used in placeA of auxiliary ink-ribbons for manifolding.

In machines of this character it is desirable to manifold collated Work-sheets, as', for example, a ledger-sheet and a monthly statement-sheet. These two are usually fed around the platen from the rear, up across the front of the platen to a collating table, where an edge of each sheet is aligned vertically and the last printed `entry thereon alinged to the wing-scales at the front of the platen. To align these two work-sheets simultaneously with a carbon-inlay and preserve uniformlyspaced successive records was a painstaking operation and re uired skill to reserve neat, uniformly-space -oif records or singly-inserted items. l

One feature of the present invention provides that the under or statement sheet may be adjusted under the platen from the rear, brought up over the face of the platen and 150 carried to the collating table or plane where one edge is aligned accurately to a side gage and the last typed entry adjusted approximately to the printing line on the platen, and the sheet then clamped to the face of a slide mounted upon the table for an up and down sliding movement. The second or ledger sheet may be similarly adjusted around the platen outside the statement-sheet and adjusted accurately to a second side gage, and the last line typed thereon also approximately adjusted to the printing position regardless of the adjusted position of the previouslyadjusted statement-sheet clamped to the first slide on the collating table. Each slide on the collating table may be moved up or down by a rack-and-pinion connection operated by a fingerwheel at each side of the collating table. By turning these two finger-wheels the ledger and statement sheets clamped to the two slides may be accurately adjusted to the front scale and in register with each other, and, when so adjusted, the released feed-rolls may be restored to hold the two sheets in adjusted relation against the platen. The clamps on both slides are now raised to release the two sheets, and the platen line-spaced for the new entry to be entered on the work-sheet. By adjusting each sheet separately to a sheetedge gage, and then clamping the sheet to a slide, prevents any shifting of the first-adjusted sheet during the adjustment of a second superposed sheet, and this not only permits more accurate registry between entries, but reduces the time required in changing the work-sheets.

The two-color typing is done on the outer work-sheet through the use of the usual bichrome ribbon vibrated across the printing pointA of the types, and also provides for twocolor manifolding for the under work-sheet through the introduction of anauxiliary bichrome ribbon-section between the two worksheets that are shiftable between stop positions to bring either field of the ribbon into a positive registry with the printing point, and thus re roduce the outer sheet with the two-color e ect.

The auxiliary bichrome ribbon-section is mounted upon a carrier, in such a manner that it can be inserted between two work-sheets to cover the printing position, and be locked at one of two fixed positions to bring either inked section to the printing zone at will, and thus vmanifold in Itwo colors, or may be removed at will when it is desired to type the outer sheet without manifolding.

Other features and advantages will hereinafter appear.

The platen 10 of an Underwood standard typewriting machine, against which the typebars 11 strike upon the front side, is supported by a platen-shaft 12 having bearings in the end plates 13 oined together by a tierod 14 and a paper-table 15 forming a platenframe shiftable up or down between two stop positions within the usual Underwood traveling carriage (not shown) The platen 10 has two feed-rollers 16 that may be cast off in the usual Underwood manner as disclosed in the patent to H. S. McCormack, No. 819,785, dated May e, 1906.

The paper-table 15 curves under the platen to a point just below the printing position, and forms a deilector or open passageway between said table and the face of the platen.

The machine is also equipped with two front collating table supports or sections 17 and 18. These are supported upon cross-bar 19 and are capable of adjustment for different widths of work-sheets, or to different positions longitudinally of the platen. The crossbar 19 may be secured at each end to brackets 20 mounted upon rods 14, 21, 22, and supported by the end plates 13 and brackets 23. Upon the front face of these two sections 17 and 18, table slides 24 and 25 are mounted for independent up and down movements over the stationary support. This up and down movement is promoted by three tongues 26, 27 and 28 secured to the under face of each slide to engage with and pass through three slots 29, 30 and 31 in each section 17 and 18. To prevent said slides from falling outwardly, the two tongues 26 and 28 are provided with lates 32 that span the slots 29 and 31 and ear against the rear face of the tables. This construction provides for a free up and down movement for the slides, and to control this movement the center tongue 27 of each slide projects beyond the rear face of the collating tables and is provided with cross-cut rack-teeth 33, Figure 3. These teeth are in mesh with a pinion 34 fixed to the inner end of a shaft 35 that takes bearings within the ears of a bracket 36, Figure 2, secured to the rear face of the collating tables with the free ends of each shaft provided with a finger-wheel 37.

The plane of the collating-table-sections 17 and 18 and the slides 24 and 25 is nearly perpendicular, and hence the slides will drop to the lowest position determined by the engagement of the lower ends o-f the tongues 27 striking the ends of the slots 30, and this lack of control over the position of the slides, at all times would defeat one object of the invention, namely, to adjust the slides and hold them in any adjusted position. To these ends each shaft 35 has an adjustable braking means comprising a compression-spring 38, Figure 8, coiled about the shaft and confined between an eaI` 36a of the bracket 36 and a collar 39 upon the shaft that prevents endwise movement of the shaft from the action of this spring 38. A second collar 40 is adjustedagainst the opposite face of the ear 36, which provides suiiicient drag against the rotation of the shaft 35 to oiiset the action of gravity on the slide 24 or 25.

Viewing the front of. the machine. as in Figure 1, the right-hand edge of the slide 24 and the left-hand edge of the slide 25 are bent forwardly at right Aangles to form long gaging faces 41 and 42. As shown in this ligure, the outer work-sheet A, which may be described as a ledger-sheet, is adjusted to the side gage 42, and the innermost sheet B, which may be a statement-sheet, adjusted to the gage 41, and the relative adjusted positions of these two gaging faces are such that there is a narrow strip along the side edges, as indicated at X, where the two work-sheets do not overlap each other, and, within this singleply work-.sheet space, a clamping means is established to bind each sheet to its respective slide 24 or 25. This clamping means, Figures 1 and 9, comprises two arms43 joined together by a rubber-coated bar to form a long pressure pad 44 adapted to swing, as a unit, upon a rod 45 suspended at each end from the ears of a bracket 46 secured -to the outer face of each side gage 41 and 42 and springpressed by one or two two-way springs 47,

arranged to hold the pad 44 in a raised-inoperative position, orto press the pad against the face of its slide at another position. The longitudinal edge of the work-sheet B engaging the long gage face 41 of the slide 24 and the long spring-pressed pad 44 pressing the work-sheet against the face of the slide, provide an effective gripping means to control the movement of the work-sheet during the movement of the slides for purposes presently to appear. The clamp is mounted to engage the sheet at the side, and is open at the top to permit the sheet to extend up past the clamp.

The outer work-sheet A is typed throu h the usual bichrome ribbon 48, fed longitu inally through the usual ribbon-earner 49, that is vibrated to cover and uncover the printing position by a ribbon-vibrating lever 5() operated by a universal bar 51 at each type action. The two longitudinal fields of the bichrome ribbon are brought to the printing position, at will, in the well-known Underwood manner, by two-color-ribbon-shift mechanism, comprising an actuator 52 having two slotted ears 53 to engage with two Wrist-pins 54 and 55 on the lever 50. The actuator 52 is settable by a crank-arm 56.se cured to a rock-shaft 57 operated by the usual ribbon-shift keys 58 and 59 over the keyboard. Further details regarding this ribbon-shifting mechanism is disclosed in the patent to J. C. McLaughlin, No. 1,066,029, granted July l, 1913.

In the present invention a section of similar bichrome ribbon, used on the ledger-sheet, is introduced between the two work-sheets and controlled by a manually-shiftable ribboncarrier, so that exact duplicate records may be made on each work-sheet in both typing and color effect. To this end each collating-tablesection 17 and 18 at the upper right and left hand corners respectively are formed with extensions, Figures 3 and 8, that projectl outwardly from the tables a short distance, then are bent forwardly at right angles and again bent at right angles away from the center of the machine; these several bends in these ca tensions result in an ear 60 at the upper corner of each collating table that is parallel to the face of the tables and are employed to support a bar or strip 61, extending across the collating tables. This bar 61 may be removably secured to the face of the ears 60 by spring-detent-clips 62 secured to said ears and formed with V-shaped terminals 63 to overlie the bar and interlock within slots 64 formed at each end of the bar 61 and to engage the upper edges 65 of said bar for locking the bar in one of two positions. In its lowermost position the bar 61 is arrested against stop 60El bent up from the ears 60. The bar 61 s-upports a cardboard-section 66 that is co-eXtensive with the width of the collating tables between the two side gages 41 and 42 and extends downwardly to the position adjacent the lower edges of said tables. This cardboardsection may be a thin sheet of hard, wiry grade of fiber-board and may be permanently secured at the upper edge to the bar 61, as by rivets. The lower end of this cardboard-section 66 has three metal fingers 67 permanently secured to the front face thereof, with one finger at the center and one near each side edge lit,

of the cardboard. VThese fingers 67 project below the edge of the cardboard and are arranged to support a long inverted U-shaped metal cli 68, Figure 5, secured to the faces of these t ree fingers, in any suitable manner, with one wall of the clip embossed to form raised-up ridges 69 within the clip to separate the two walls thereof, and thus provide an open longitudinal gap at the open end of the clip. This clip 68 may be formed from thin resilient metal, so that the wall not secured to the fingers may bear against the faces of the ridges 69 under tension. The clip 68 is arranged to support an auxiliary ribbon-carrier comprising a stiff paper-tongue 70 that may be forced within the opening between the two walls ofthe clip 68 by riding over'the ridges 69 and flexing the o posite wall of the clip, in such a manner t at an effective grip on the paper is maintained. The paper-tongue 70 extends downwardly from the clip 68 to a position below the printing line on the platen and is provided with a long rectangular slot or opening 71 aligned to the printing posit-ion of the platen. This slot is covered over on the front side by a bichrome ribbon-section 72, and the width of the slot may be approximately the same width as the ribbon, but the ribbon may be slightly longer than the length of the slot to provide that each end of the ribbon may be permanent-ly pasted to the paper-tongue 70 and effectively cover the whole area of the slot.

As shown at Figure 6, which is a front elevation, the lower field of the bichrome ribbon 72 is at the printing line across the platen. To change this ribbon-field the projecting ends of the bar 61 may be gripped by the operator and the bar forced downwardly against the stops 60 and until the detent 62 interlocks with the edge 65 of said bar whichI lowers the ribbon-section 72 and moves the ribbon-section 72a to the printing position.v

Hence the up and down adjustment of the bar 61 to one of the two detent positions changes the operative longitudinal ribbonfields relatively to the printing line and provides that ribbon-inked manifold may be produced in a uniform color, or selectively in varying colors in the same line at will.

As previously described, the ribbon-section 72 is permanently secured at its ends to the front faces of the paper-tongue 70. As the ribbon-tongue must be introduced between the two' work-sheets, it is obvious that the 'front exposed face of the ribbon will be brought into contact with the rear face of the front work-sheet A, and typed impressions will not only be transferred to the back of this sheet, but the exposed ribbon will cause more or less crocking; both features indicating a waste of ink from the very limited supply carried by the short ribbon-section. To conserve the limited supply of link available in so small a ribbon-area, a cover of thin paper 73 may be pasted to the paper-tongue 70 to cover the whole ribbon-sectlon, which not only prevents smearing the adjacent face of the work-sheet, but prolongs the life of the ribbon.

From this description it will be seen that the auxiliary ribbon-carrier, comprising the two paper- elements 70 and 73, may be assembled for various lengths of work-sheets and for various colors in the bichrome fields; that the carrier as a unit may be instantly removed from the clips and replaced by another carrier having different colored ribbon-fields, and, while the invention has been shown and described for a bichrome ribbon, it will be understood that an auxiliary ribbon of a single color may be employed when the bichrome features are not.desired.

From this description the operation will be readily understood to be as follows: The two slides 24 and 25 are adjusted to a central position on the collating tables; the bar 61 and its attached parts are removed as a unit; the two pads 44 are raised to inoperative positions, shown at Figure 6, and paperfeed-rollers 16 are released to the inoperative positions, shown in Figure 3. The first sheet to be adjusted is the sheet next to the platen-face which will be called a statementsheet B. This sheet is forced under and around the platen from the rear, and guided by the deflector 15 and the usual wing-scales 74 at the front of the platen to thecollating table. If previous entries have been made on this sheet, the sheet is drawn upwardly from the front until the last printed line is above the edge of the scales 7 4, and, without accurately aligning this printed line to the scales, the right-hand edge of the sheet is aligned to the gage 41 of the slide 24, and the pad 44 attached yto the side edge of the slide is snapped down to press the sheet firmly against the face of the'slide underneath, as shown in Figure l. A second worksheet A, which may be a ledger-sheet, is forced around the platen and around the adjusted sheet B until the leading edge of the sheet is brought up over the collating tables where the last typed entry thereon is approximately aligned to the scales 74, and the left hand edge accurately aligned to the gage 42 and the associated pad 44 snapped down to bind this sheet to the face of the slide 25. The adjustment of these two separate worksheets as described allows the operator the use of both hands to quickly and accurately adjust each sheet separately to a side gage, and, when both sheets have been adjusted and clamped with slides, the operator employs both hands to turn the two fingerwheels 37 which move the slides 24 and 25 up and down to adjust the last typed entry on its work-sheet to the edges of the scales 74, and, when so adjusted, the feed-rollers 16 are restored to press both work-sheets A and B against the face of. the laten, the two ads 44 are raisedto-release t e work-sheets the auxiliary ribbon in a fixed longitudinalposition relative to the printing line. As the usual entries on the outer sheet A are made through the upper or black section of the ribbon, the auxiliary ribbon will also be adjusted to bring the ,upper or black field of the ribbon tothe rinting position through the interlocking o the detente 62 with the edges 65 at each end of the bar 61.V These several adjustments havin been completed, the usual center roller 6'is swung toward the platen to bear against the outer face of the sheet A to taken any sag in thework-sheets and still lleave t e sheets loosely positioned to enable subsequent line-spacing movements to be made without disturbing the position of the auxiliary ribbon-earner. The impact of the type against vthe usualvibrating ribbon 48 transfers inked characters to the ledger-sheet A and manifolds these characters through the auxiliary'ribbon to the statement-sheet B in the same color. And should occasion arise to enter a debit transaction' on the ledger-sheet in a 'distinguishable color, the usual bichrome ribbon-shift-keys 58 and 59 of the Underwood machine provide that the lower field of the ribbon may be vibrated to the printing' position, and, by. liftingthe bar 61, the slots 64 lwill interlock with lthe detent-springs 62 and the lower section of the auxiliary ribbon will be moved to cover the printing zone of the types, as at Figure 6,

and the debit transactions entered on the. ledger-sheet through the red section of the standard ribbon 48 will be maiiifolded to a entire face of the sheet B, at the end of the last typing operation on -the sheets and before the sheets arevremoved, a pencil-mark in-l dicated at 77, Figure .1,v may be drawn on sheet B adjacent the right-hand edge of the sheet A, indicating the last line position on the sheet to assist in readjusting the sheet B when it is adjusted to the printing osition for subsequent entries. This mar 77 is essential because the typed matter on the under sheet B is covered by the outer sheet A. The typewritten entries on the two worksheets having been completed, the center roller 76 is swung out of the way, the bar 61 is removed from the ears 60 to withdrawn the auxiliary ribbon from between the two worksheets, and the two feed-rollers 16 are thrown while the machine has been iemi'l'm1 s4 beingadapted for typing la ledgerssheetlnd j, 'l

tween the two superposed work-sheet"an`d providing shifting means for this a `ribbon so as to'fenable the o rator to maml* fold the under sheet in exact y the Same form and characteristics sheet.

asv typed on the outer It will also be noted thatv in providing"l y. Y means, whereby this auxiliary ribbon may be f detached from the collating tables the co1- he tables Y and guides 'may be emiloyed for manifoldwork where it is more a vanta eous to insert lating features associated with -t carbon-inlays between two wor -sheets before they are adjusted around the platen, the pads 44 being raised to inoperative itions.

It will also be understood t at in someforms of work-sheets employin ruled lines,

these ruled lines may vary with t e two work` l sheets and require individual adjustments of the sheets without employing the usual line-.1

spacin device. 'This may be readily accomplishe by line-spacing `each sheet independ ently to the printing position by turning the fingerswheels 37 to draw their work-sheet around the platen distances thatvary with the spacing of the ruled linesof the two worksheets. v

In some forms of supe osed work-sheets,

itmay be advantageous at intervals to silence i a the vibrating ribbon to enable t d entries to bev manifold'ed on the unders eet without making any record on the outer sheet., YTo` this end, `the usual Underwood ribbon-shifting mechanism includes a shift-lever 78 that operates to rock the shaft 57 and `move the osition rel' actuator 52 to an inoperative ative to the two wristins 54 an 55, and the ribbon48 will remain inactive-below the eld of the types, in a mannerl disclosed in the l [lll patent to J.v C. McLaughlin, No.' 1,211,203, granted January 2, 1917. By'raising the fue g bar 61 to' rest upon the iiaring ends of thel spring 62, the auxiliary ribbon maybe rende'red temporarily inoperative, when records are made on the outer sheet o ly.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used vwithout others. Y
