To all whom may concern:

Be known that T, ARTHUR A.. JOHNSON, a citizen of the United States, residing in borough of the Bronx, in the county of the Bronx, city and State of N ew York, have in vented eertainnew and useful .improvements in Typed/'Writing Machines, of which the fol" jlowing is a specification.

This invention relates to an `improvement in `typewriting machines, and more espe cially to an attachment known as the fanfold, for typewriting simultaneously a plurality of .copies of the same piece of work, and repeating th'e operation continuously for a number of pieces of work of like character; The invention is shown as'applied to an Underwood typei'vriting-machine.

ln the present disclosure of the invention, the work-sheetsare fed around the 4platen' from continuous strips and cut off after being completed. The sheets are interleaved by carbon sheets, so that the writingon the uppermost sheet may be copied Onto the other sheets. nasmuc-h'as the carbon sheet-s may be repeatedly used for a large number of separate pieces ofA-work, andone'object ofthe present invention is to provide for such re )eated use, it is necessary to space the wor -sheet strips relatively to the car bon sheets.` This is done inthe present casev by"withdrafwing t-hev pack, comprising the Intel-mingled carbon work-sheets, toa-position clear of the platen, so as to ellminate .the bend around the platenand thus lessen the friction between the carbon sheet and the work-sheet. -Then the work-sheets are advanced relatively to the carbon sheets toV bring a fresh sur-face of the work-sheet webs into register with the f carbon sheets. vThe pack comprising the carbon sheets and the new portions of the work-sheets is then ad- Yvanced as a unit to-a position around the platen ready to be written upon.'v

The carbonsheets are herein shown as mounted-on rolls off to one sideof the line of travel of the Work-sheet webs or strips,

and are turnedatright anglesto a'position to extend in line with the vwork-sheet webs.

Guide plates, having edges placed yat 45 degrees with respect to theline of travel of the work-sheet webs, turn thecarbon sheets and interleavethem between the work-sheet stripsa The carbon rollers are connected to be driven positively from the platen, so that the carbon sheets will move in unison with Specification of Letters Patent.

the platen both in feeding fo'rward with the platen and lin withdrawing them from the platen. Feed-rolls for the worksheets are alsov connected to be driven from the platen, `so that the work-sheets may be withdrawn with the carbon sheets.v Thus, thev carbon sheets and the worksheets, when being withdrawn prior to a spacing action, may be driven from three points inunison.

The'spacing of the work-sheets relatively to the carbon sheets vis herein shown as accomplished byljocking the drive tothe carbon rolls, and releasing the drive from the 'work-sheets, at the saine time releasing the pressure feed rolls from the platen'. Under sheets, so that the work-sheets can be drawn `-fon by hand to properly space and position fthe work-sheets and carbon sheets. This withdrawal of the knife is accomplishedl by` I the releasing of the pressure .feed4 rolls, to en- `abletlie pullingon the Aworksheet toA take place whenthe rolls are clearedv froin'the platen. l

A gage is herein shown as provided some distance above the knife, to which the top edges ofthe work-sheets can bedrawn, to determine the length ofv work-sheet to be cut oft'. The kniferis adjustable to 'vary the length ofthe work-sheet, andthe gage is Y 4also adjustable.v A guide is shown as pro-` vided 'for deiecting` the work-sheets from .the gage during Va normal typewriting ac-A tion, and this guide lis depressed out of the wayi. ,o"permit the use of the gage when the mechanism is adjusted for withdrawing'a V,completed work-sheet from the platen and gaging the same.

Other features and advantages will hereinafter appear.

Fig. 7 is a view taken similar to Fig. 6,.

except that the assembled pack of intermingled work and carbon sheets have been advanced to a f ull -bill-space, showing that the. 'piece of work, such as a bill, has been co1n-r pleted. This corresponds to a condition of the parts just prior to that of Fig. 6.

'The platen 1 about which the assemblageor pack of interleaved carbon and Work? sheets is partly wrapped `or turned during a' typewriting operation, is securedto an aXle 2. mounted torotate in platen frame 3, which is mounted in the usual manner on the typeT writer carriage.

.that lthere are" 'two carbon` rolls` 'on' each side of the' mainframe 30./ I

order-to driveI the .wbrksheet strips and thel carbon sheets .atf the same 'timev as the .platen is' cl-riveli', lso that' the"l rear portions paceiwith l theimovementlof those. portions rasante ofthe sh'eets'vwmch are Wrapped around the I on ahorizontal shaft 46, extending to al position vabout midway ofthe frame-30. At

this point, the horizontalshaft' 46 is provided witha bevel gear 47 meshing with a corresponding gear-48 on avvertical shaft 49. On this .vertical shaft 49, there is provided a pinion 50, which meshes with a pair of driving rack bars 5 1 and 52 which are oppo-v sitely -facing, so as to engage the pinion 50 at opposite sides. The pinion v50 can thus 'Spread or retract the guiderack bars 51 and 52, according to the direction of rotation of thefplaten 1v. 1n addition to the racks which mesh withthe pinion 50, the ,drive rack bars 51 and 52 have .auxiliary racks on their under sides at 53 and 54V to mesh with and drive four pinions 55, one on each o'f/.the carbon' roll shafts 34.

The carbonl sheets27 are wrapped arpund the rolls29'in suchet-manner, and the driving train from the platen axle 2 is so arranged, that the carbon sheets will `be fed in the same direction at the carbon rolls as they Vare `at thep'laten. In this way, the

carbon sheets can keep pace' withl the linespace and advancing movement ot the platen, and also can Withdraw the carbon sheets from the plat'enas the latter is reversely. rotated.

Inaddition to.driving the carbon rolls from the platen, the rear work-sheet ,feed rolls 19 .and .20. Vare also .driven from the platen. Forv this purpose, the shaft 40, Fig. 5, is-provided witlranother'bevelgear 56, ,which VKdrives a bevel gear 57.* The bevel gear 57 has securedl to it, for rotation there' with, a pinion 58 which' drives a pinion 59 secured 'to the faXle 22 for tl1e.'work; s'heet feed roll 20. The other feedingro1l19 for `the 'workfsheet `strip is normally :pressed toward the roll Q0 by means of one ormore springs 60, which engage sliding' yblocks 61 forming floating bearings for the 'axle 21.

-In thisway, the two ro11s`19 and 20 normally grip the Aworksheet strips 17, sofasto advance them with, .the advancing 1novementof the platen, `and. may also act to Withdraw the work-sheet strips from ythe platen with a reverse rotationof the platen when tak-ing out the bend in the pack of assembled sheets.

' Then it is desired to withdraw the work` sheet strips by hand, the roll 19 maybe moved to an inactive position by means of a pair of shifting cam arms 62` secured to a shaft 63. These. arms raise the roll 19 link 65 te the'bell crank ot" the finger-piece 16. inasmuch as the driving trainis pret- *i5 erably locked when the sheets are so with'- drawnl while the feed rolls 19 and 20 are released, there is provided a dog 66 arranged to be swung into engagement with. the teethr of the gear 59 when the pressure ifollsj, 6 and 19 are rendered inactive. This dog 66 is pivoted to one of the arms 62 and yieldingly held to its'work by a spring 67, so as to prevent breakage oi' the parts in case it should engage on theend of one of theteeth of the. gear 59.

naddition to drivingthe platen 1 by the line-spaee-lever 4, it may also be driven both reversely and in an .advancing direction a vmajor amount, so asto withdraw the pack of 'work-sheets and carbon sheets, vdisplace them, and return .them -to theplaten. For this purpose, the platen axle 2 is provided,

at the opposite end from lwhich :the gear 33 the platen, the hand-crank 70 is forced rearwardly at its upper end.

t'portionlof the movement of the hand* crank 70 is set oli for the purpose of cover- 105 ing theV distance froml a sheet guide-roll 7 2 vto .the printing point 73 lon which type-bars 74` strike the Worksheet on the platen.

vThat is to say, \\f'hen the pack comprising ,the interleaved work-sheets and carbon sheets is withdrawn reversely from thelplaten. -o`r spacing purposes, the leading edges ofthe. `carbon sheetswill come toa [point indicated at 7 5, Figli, just behind the.

roll After new `pcrtions of the work- 11-5 sheetshave been brought in register with the ,carbon sheets `-the Work-sheets and carbon .sheets arebrought around to a position Where vthese ileading edges of the carbon sheets are just above the printing point 73.

Inl orderthat this portion of the motion of 4the rotation vofthe platen and the motion of the hand-crankO may be automatically determined, there is provided an intermittent gage stop, Fig. 2,. .This stop comprises a plunger 76 guided against rotary movement and sliding through the body portion of the gear segment 69. On one end, the plunger 76 is provided with a head 77 normally held clear of a fixed stop 78 by means of a. spring 130 ,platenthe other end of the plunger brings a cam surface 80 thereon into engagement with -a cam surface 81 of a one-way acting tappet or dog 82 which is mounted on the frame. The .relative position of the dog 82 and the "stop 781s such that as the khand-crank 70 is swung witha quick motion, the plung'ervv will' be projected by the dog 82, sogthat `its head will engage the stop 78 before the spring7 9 can return the plungenwhich has cleared the dog 82, to its normal position. This will stop the hand-crank 70 so that the operativeknows then that the interleaved packfof work-sheets and4 carbonl sheets 1s properly positioned for the initial line of writing. The dog 82 is pivotally mounted on a support 88, so that it will yield when the abrupt face of the plunger 7 Gengages the abrupt face of the dog 82. A spring 84: will returnI the dog y82 to its normal position after the plunger 76 has escaped past the dog;

The work-sheets, and lwhen typewriting is going on' the carbon sheets also,`pass from frame 85 and beneath a cuttingfoif knife 86'. The knife^86 is adjustably mounted on a movable slide 87, so that it can be placed at a number of positions withreference to a scale indicated [by the numbers 5, 6 and "7 which may correspond to the number of lines in the bill or other piece of work. The adjustment is for the purpose of varyin the length of the `work-sheet, Such as a lhill, and the'numbers correspond to five, six and seven lines of typewriting'. Normally, the. knife 86 and its slide 87 are in araised position, corresponding to the position they occupy for cutting off the l work-sheets.- When, however, it is deslred 3 Ato catch hold of the pack of work-sheets to draw them around the platen by hand this coincident with `the requirement of releasing' the pressure feed rolls 5 and 6-,the slide 87 is operated from the release fingerpiece 16.

Forthis purpose, the bell crank of the finger-piece is provided with an arm 88 connected `to the slide87 by a link 89. The link89 and l-the arm 88 forma toggle with their pivotal point of connection on one side of the line of centers, as in Fig.-5'. When releasing the pressurerolls 5 and 6, the toggle is first straightened and then collapsed again to a greater distance to the Fig. 6'position, which lWillwithdraw the bail and knife to a position, permitting access tothe leading edges of the worksheets, as in Fig. 6. For steadying the movement of the knife 86 and its slide 87, there are provided pinions 90/secured to an axle mounted on the slide 87 and engaging racks 91 on each side `frame 85.

osition ef To gage, the leading edges of the workf sheets as they are drawn from the platen` before cutting them 'ofwith the knife 86', there is provided a gage 92 adjustably. mounted by means of set screws v92a (Fig. 5), -on vertical extensions 93 of the guide frame 85. This gage 92 projects forwardly from the face of the extensions 93 at', both its ends, and is connected between these pro'- jectmg parts by a crosse'bar 94vwhosexfront Aface is below the frontface of the projections. l

The form of the gage 92 enables the work-sheets tobe properly squared as well as gaged, and also leaves room for a deector 95 'to be dropped beneath the projecting faces of the gage 92 for a gaging operation. Normally, this deflectoi` is raised to the full line position o f Fig. 5, so as to clear the worksheets from the gage as the typewriting goes on.

-As the'. gagingI operation takes place just subsequent to the drawing forward of the work-sheets by hand, the-deflector is permitted to recede when the pressure rolls 5 and 6 are released by the finger-piece 16. In other words, the deflectoris mounted at its lower end o n guide-frame-S and nor- 96 pivotally connected to a 4lever'97 and ofthe guide),y I*

Vmally held in a raised position bya shifter i guided by extending through an opening in the frame85.. Thel tail end of the lever 97 engages a pin 98 provided on the slide' 100 87, so that this slide when raised toits cuttingoff position, which corresponds.t0l the normal typewriting position, will swing` the,

lieflector 95 yto itseffective fullline position,

ig. 5. y

hen the knife`86 and its slide 87 are withdrawn'for shifting of the work-sheets and catching the same, the vpin-98 recedes,

permitting` the deflector 95 to fall toits ineffective dotted line position of Fig. 5f

, The operation ofthe device `w-illvberead- .ily understood when taken lin connection with the above descriptionz .If itis assumed that a pieceof work, such -as a bill, 11'5.-

has just been completelywritten,the pack of work-sheets'and carbon sheets will oc` cupy thevposition of Fig.-7, with the upper endsof the'carbon sheets projecting onto thel guide-'frame 85.

'In order Ito space thjewrk-sheeti strips relative to the .carbon sheets, to bringja` `fresh surface of the work-sheet strips Yin' register with the activeportion 'of-the carbon sheets, it is first necessary towithdraw reversely the pack comprising the assembled the hand-crank70,- whichfis'at this, time nears-its foremost position,` depending upon- 412.5 work and carbon sheetsxy For this purpose',

the length ofthe pieceofwOrk, must beA .forced rearwardly to the'Fig. 6 position'.

Lasserre s.,

This motion of the hand-crank will rotate the platen 14 reversely, so as to move back the pack of work and carbon sheets, and at the same time will drive the feed rolls 19 and 20"reversely, so as to draw back on the work-sheet 17.

The gearing, it will be remembered, is also connected to the carbon rolls 29, so that they will (be ,reversely' driven to wind up the carbon sheets 27. This continuesuntil the hand-crank 70 comesto the limitof its movement, as in Fig.'6, when the carbon Whole free stretch of sheets and the'portlon of the 'work-*sheets just previously Written upon will be drawn straight; out, in the rear of` the guide-roll 72, so that there 1s no bend in them, and so that they are separated, minimizing the friction betweenthe carbon sheets and the work-sheetl strips '17.

The 4work-sheet strips may now be pulled 4forwardly to advance them relative-to the carbon sheets'. In the present case, this. is done by hand; lthat is to say, the operative ltakes. hold of the sheets and pulls them around independently ofl the platen. In

order to permit this relative movement be' tween the platen and the work-sheets, the

i 19, out of co'perative relation with the feed release-finger-piece 16 vis depressed, which will disengage thepressure feed-rolls 5 and 6' from the lwork-sheets, andA also, through the connecting linkage, shift the feed-roll roll' 20. The dog 66also acts' at this time 'to lock the train of gearing from the platen. to the feed-rolls 19 and 2O and carbon rolls 29, thus enabling' the workesheet Strips to be' drawn forward while the carbon sheets remain stationary.

As lthe sheets may occupy somewhat the position of Fig. 6, it' is .necessary tn withdraw the knife 86 from its Fig.l 7 posltion to its Fig. 6 position. This is taken care of at the same time that the feed-rolls are released, by the finger-piece 16. This action, as explained above, also depresses the detlectorl 95, permitting access to the gage 92. The operative then grasps the top edges of the projecting Workesheets 17 and draws them up until the leadingedges engage the gage 92. This gage has been previously adjusted with an ladjustment of the knife 86, correspending to the-'length of work-sheet desired. The release finger-piece 16 may then y .be restored to its normal position, unlocking the train of gearing, bringing the pressure lfeed-rolls 5, 6, 19 and 20 into play, and restoring the knife-blade 86 to its normal raised position. The Apack of sheets may then be warped across the edge of the knifeblade, -severing the projecting portions of the strip 17, bearing one piece of work, such asa bill. The restoration of the finger-piece 16 also raised the deiiector 95 to its normal full-line position, Fig-5, so that in typewriting subsequently, the leading edges .of

guided over and be 4may now be advanced asa unit from the Fig. 6 position to a position such that the --rst line to be written on, backed up by ycarbon sheets, will come to the 'printing point 73.

To effect this advancement, it is merely necessary to swing the hand-crank forward with va rather quick motion, when the. plunger 76 will be automatically thrown out to temporarily` engage'the stop 78, thus bringing the hand-crank toa stop. The plungerA is so located, as before described, that it will 'limit temporarily the rotation ofthe platen, the feed-rolls 19 and 20 .and the `carbon rolls 29 an extent suthcient to feed thev packv of assembled sheets'from the point v ('Fig. 6), to the point 73 (Fig. 7).

The type-bars 74- 1can now be operated to Write the new piece of work, and the platen spaced, line by line, by means of the line. space lever 4. This movement will also drive 'the' feed-rolls 19 andA 2O and the carbon rolls 29, enabling the work-sheet strips 17 and the carbon sheets28 tomove along' at all points at substantially the 'samespeed, thus eliminating any drag which might tend-to displace the sheets relative to the platen.

`When the piece of Work is finished, the parts again come to the position, Fig. 7, and the pack of assembled work and carbon sheets may once more be withdrawn to straighten outR-the bend and eliminate fricl tion between the carbon ,and work-sheets.` Then the work-sheets vare pulled" forward relatively to the carbon sheets to get the required spacing, and the pack'once more brought to the printing point for still another piece of work. Thus,the same sheets of carbon paper can be used repeatedly with different sections of continuous strips of work-sheet until the'carbon sheets are worn out, when they can be replaced by removing the carbon rolls 29'.

When the worksheet andcarbon sheets are retracted to permit the relative movement of the work-sheet to the carbon sheets, the first line of writing on the last written form'is moved rearwardly away from the ,platen and is located directly above the roller 72, as seen inlfig. 6.

In order that lthe work-sheets, when thus retracted, will not be moved out of the bite of the feed rolls, a surplus amount of worksheet is always left on the web. That is to say, there are always two forms eitherpreviously written on or left blank still attached to the form being written upon. This is done, because, if the form written upon i When't-he carbon 'I being slid onto pins 102' secured-to the frame "guide-plates.
