21 Claims. 7 ((71.197-126) This invention relates to paper and carbon feeding mechanism adapted for use in combination with a printing or typing machine. More particularly, the invention relates to an apparatus for controlling the movement of carbon sheets with respect to a plurality of continuous webs of paper which is fed through a typewriter in a manner that the carbon sheets can be used many times for reproducing copies of information typed upon the paper webs. g

The carbon feeding apparatus is constructed and arranged so that the carbon sheets can be fed through the typewriter with the plurality of continuous paper webs for reproducing information upon the webs. After'the desired information has been typed the paper webs and the carbon sheets are moved rearwardly out of the typewriter and the carbon sheets are retained by suitable mechanism so that the paper webs alone can be advanced through the typewriter to permit removal of the portion of the paper webs which has the information typed thereon. After a predetermined length of paper web has passed through the carbon feeding mechanism the car bon sheets will be released to permit the same to advance with the paper webs so that when the portion of the webs. has been removed upon which information has been typed the. paper webs and the carbon sheets will be in position for subsequent typing operation. The apparatus is especially adapted for typing information upon repeated forms printed upon the face of continuo webs, such as multiple bill forms.

An object of the invention is to provide a carbon feeding attachment for a printing or typing machine wherein .the movement of the carbon is automatically controlled.

' Another object of the inventionis to provide an improved automatic carbon feeding apparatus for attachment to a conventional typewriter or printing machine which relieves the operator of a carbon feeding apparatus for a typewriter which is constructed and arranged to permit the type-.

writer to be used for normal typing operations without removing the carbon feeding apparatus from the typewriter. I

Another object of the invention is to provide a mechanism for longitudinally aligning form faces printed on superposed continuous webs by engaging'a weakened line, such as a perforation line or fold line, extending transversely of the webs after completing preparation of one of the Another object of 'the invention is to provide an improvedacarbon feeding attachment which is adapted to release the carbon to permit the same to move forwardly between a plurality of adjacent paper webs, after a determined length of paper web has passed through the carbon feeding attachment. e

Another object of the invention is to provide a carbon feeding attachment for printing or typing machines wherein the forward movement of the carbon sheets is controlled by a predetermined length of paper web passing through the carbon feeding attachment and the rearward movement of the carbon sheets with respect to the typing niachine conditions a mechanism for measuring a length of paper web passing therethrough.

form faces so that the subsequent form faces on superposed webs will be aligned just prior to their use in a typing machine with which the aligning mechanism is associated; the fold line or perforation line also being used as a tear off line so.

that each form face can be separated from the continuous web, the aligning means also providing means for separating the completed form faces from the continuous web.

The apparatus of this invention is adapted to be used in combination with a typewriter or printing machine wherein a plurality of paper webs is passed through the machine in adjacent relationship for producing multiple copies of desired information. Particularly, the apparatus is adapted to control the movement of carbon sheets which are placed between adjacent paper webs to produce the multiple copies. The paper webs have printed faces which are repeated upon the surface of the web to produce bill forms or the like which can be fed through a typewriter in a continuous web. The carbon sheets are adapted to be used several times and since the paper webs are continuous, the carbon sheets must be moved with respect to adjacent forms after the information has been placed upon one of the for s taken along 4 so that the carbon sheets will be disposed adjacent the subsequent form upon the web when the form is carried over the platen of the y writer. The webs can be arranged in a fan-fold pack with or without a perforated fold line to permit severance of individual forms from the webs, or they can be flat webs with a perforation line between adjacent form faces.

In this invention the carbon feeding apparatus is constructed as an attachment which can be associated with any conventional typewriter. As shown in Figure 1, the carbon feeding apparatus H! is shown in position adjacent a conventional typewriter IS. The typewriter I5 consists of the usual frame I l supporting a carriage l2 which in turn supports a platen I3 having a knob ll for rotating the platen l3 manually. The standard keyboard [6 is carried by the typewriter l5. In all respects the typewriter i5 is of conventional construction and it is therefore believed further description of this apparatus is not necessary, The association of the platen I3 and the carriage l2 of the typewriter with the carbon feeding apparatus ill for producing cooperative action therebetween will be hereinafter more fully described.

The carbon feeding apparatus l3 consists of a frame ll for supporting the carbon feeding apparatus Ill in adjacent relationship with respect to the typewriter IS. The frame II has a base I! adapted to rest upon a table or other support. The base [3 has a cast body i3 secured thereto by-means of a bolt 26. A bolt 2! is threaded into the body 19 and is adapted to engage some part of the rear wall of the frame ll of the typewriter ii for positioning the frame I! and thus the carbon' feeding apparatus with respect to the typewriter l5. A hook 22 is pivotally mounted on the body [3 by a pivot pin 22-. The shank of the hook 22 extends through the pivot pin 23 into threaded engagement with the thumb screw 23. The hook 22 is adapted to engage the rear wall of the frame ll of the typewriter ii at a point adjacent the bolt 2| to secure the frame I I against the head of the bolt 2|. The thumb screw 24 tightens the hook 22 upon the typewriter frame H.

The frame H for the carbon feeding apparatus has two

rods

25 and 26 extending transversely thereof and in parallel relationship. A frame 21 is carried upon the

rods

25 and 26 by means of rollers 28 and 23 in engagement with the

rods

25 and 26 respectively. The rollers 28 and 29 are suitably secured to the frame 21 and have arcuately curved surfaces 30 and 3| for engaging the surface of the

rods

25 and 26. The frame 21 is thus supported vertically adjacent the

rods

25 and 26 for movement along the rods as caused by the typewriter carriage in a manner to be here-' inafter described. A U-shaped member 32 is secured to the frame 21 and extends around the rod 26 as a safety measure to prevent the rollers 28 and 29 from leaving the

rods

25 and 26.

The frame 21 supports the bed plate 33 in the carbon feeding apparatus H]. The bed plate 33 is constructed in two part consisting of an upper section 34 and a lower section 35. The upper bed plate section 34 is a flat plate having channel shaped edges 36 (see Figure 15). The lower bed plate 35 is also a flat plate having channel shaped edges 31 (see Figure 15) which are of sufficient dimension to encompass the channel shaped edges 36 of the upper bed plate 34 to permit the channel shaped edges 36 of the bed plate 34 to slide within the channel shaped edges 31 of the bed plate 35 whereby the longitudinal dimen- -of ,the thumb screws 56.

40 extending from the end thereof which project.

downwardly into the recess 38 in the upper bed plat portion 34 to prevent paper webs passing 7 'over the bed plate 34 from becoming entangled with the edge 4| of the lower bed plate portion 35. The bed plate .

portions

34 and 35 are retained in properly'adjusted relationship by mean of a Y 46 extending therethrough to prevent movement of theclamp 42 with respect to the plate 45. A

threaded rod 41 extends from the clamp 42 through the plate 45. threaded upon the rod 41 for binding the channel shaped edges 36 and 31 of the bed plate .por-

'.tions 34 and 35 between the clamp 42 and the supporting plate 45.

The supporting plate 45 has a pair of threaded rods 49 extending therefrom upon which thumb screws 58 are threaded. The rods 49 slide within slots 5| provided in a supporting plate 52 extending from the frame 21 whereby the bed plate 33 is supported upon the frame 21 and can be adjusted vertically with respect to the same by proper location of the rods 49 within the slots 5| and binding the rods into position through means The bed p1ate 35 is provided with a supporting plate 45 adjacent each side edge thereof for engagement with a supporting plate 52 extending upwardly from the frame 21. v

A paper guide member 53 extends from the lower bed portion 35 and is movable with respect to the same. This paper guide member 53 is provided with a rolled edge 54 which is positioned between the under side of the lower bed portion 35 and a retaining-member 55. The retaining member 55 has a portion thereof in spaced parallel relationship to the bed plate portion 35 and has a hook portion 56 adapted to be engaged by the rolled edge 54 of the paper guide member-53 when it is desired to remove the paper guide member 53 from its adjacent position with respect to'the back plate 51 of the typewriter. Normally, the paper guide 53 engages the back plate 51 to direct paper webs passing over the bed plate 33 toward the platen |3.

To provide connection between the carriage I2 of the typewriter and the bed plate 33 of the carbon feeding apparatus for moving the bed A thumb screw 48 is that the frame 68 floats upon the

pins

63 and 64. Thi arrangement is such that the movement of thecarriage |2 of the typewriter vl5 is not transmitted directly to the bed plate 33 forcing the carriage of the typewriter to move the entireweight of the carbon feeding apparatus-upon each successive motion, but rather the frame 68 moves with the carriage and'through means of the floating action between the frame 60 .and the bed'plate 33, the bed plate-33 can follow up the movement of the frame 60 in a slightly lagging relationship.

The arms 6| and 62 of the name so are connected together by means of a writing or erasing table 18 to maintain the arms in substantial parallel relationship. A tie rod ll aids in holding the arms 6| and 62 in their proper relationship. A roller 12 is carried upon a plate 13 which is pivotally mounted upon the arm 6| by means of the pivot pin 14. The plate 13 has a pin 15 ex: tending therefrom through a slot 16 provided in the arm 6|. A thumb screw 11 is threaded upon the pin 15 to retain'the plate 13 in a properly adjuste'd position. The roller 12 engages the platen l3 of the typewriter for supporting the frame 68 in adjacent relationship to theplaten I 3. Adjustment of the plate 13 permits adjustment of the frame 68 with respect to the platen 3. A similar roller 18 is provided upon the arm 62.

To retain the frame 60 in proper relationship with respect to the carriage i2 of the typewriter adjusting screws 19 and 88 are carried by the arms 6| and 62 respectively for engaging the side walls or some stationary part of the carriage l2 of the tween the arms 6| and 62 for arranging paper webs extending through the typewriter in longitudinally aligned relationship when a typed form is completed and is to be torn from the continuous web. This means consists ofa pair of rollers 8| and 82 suitably mounted in the arms 6| and 62. The rollers are arranged in parallel relationship, the upper roller 82 having th extending shafts thereofdisposed in the slots I15. A tear-off and web aligning blade 83 is pivotally carried upon an actuating lever 84 which is pivoted vupon the pivotpin 85. One of the actuating levers 84 is provided upon each of the arms 6| and 62 of the frame 68 and is interconnected by means of a-rod 86 to form the handle for the levers 84.

A spring 81 is connected between the lever 84 and plate 33 in unison with the carriage 2 a frame 66 is provided. The frame 66 consists of a pair of arms 6|" and 62 which are pivotally mounted upon

pins

63 and 64 projecting from the sup porting plates 45 secured to the upper bed plate portion 34. Helical springs 65 and 66 are positioned upon the

pins

63 and 64 and have their inner ends in engagement with the arms 6| and 62 respectively. The

spring

65 and 66 are retained under compression by means of screws off and aligning blade 83 out of engaged relationship with respect to the rollers 8| and 82 whereby paper webs can pass freely between the tear-off and aligning blade 83 and the rollers 8| and 82.

To' retain the paper webs passing over th bed plate/33 in engagement therewith and to prevent buckling of the paper when the webs are moved in a reverse direction by means of the platen l3 of the typewriter a paper bale 88 is placed in engagement with the lower bed .plate portion 35. The fiiaper bale 88 consists of a wire frame 89 having a plate 90 secured toadjacent parallel arms! 9| and 32 of the frame 89. A leaf spring 93-is secured to the plate 98 and is adapted to extend angularly upwardly therefrom. The free end' of the leaf spring 83 has an upwardly bent portion 94 which forms an angl with respect to the main body of the leaf, spring83 to form a 3 plate a. The

springs

65 and 88 are balanced so V-shaped channel which engages the writing table 10. The upward tension of the leaf spring 93 retains the bale 88 in engagement with the bed plate 33. The degree of tension of the paper bale upon the bed plate 33 can be regulated by means of an adjusting screw 95 which is in threaded engagement with the leaf spring 93 and bears against the plate 90 of the paper bale 88. A pointer I16 is slidably carried upon the bale 88 that is adapted to be positioned upon the bale so that it will provide means whereby an operator can gauge the position of a fold or perforation line with respect to the tear-off or aligning blade 83. I

When a completed form is to be removed from the continuous web of forms the platen I3 is rotated by the operator to feed the webs I42, I48 and I44 downwardly over the bed plate 33 and upwardly past the rollers 8I and 82 until a perforation or fold line in the webis in alignment with the pointer I16. A fold line 180 is-then in position adjacent the tear-off and alignin blade 83 as shown in Figure 16. The blade 83 is then moved inwardly against the webs, the blade being directed somewhat downwardly toward the roller 8! to engage thewebs I42, I43 and I44 in a. manner that they will be caused to shift with respect to one another when the webs are retained between the blade 83 and the roller BI and the blade rides upwardly over the surface of the roller 8I, as shown in Figure 17. The blade 83 strikes the perforation or fold line in the webs and thus causes them to shift and be aligned thereby. 1 y

The blade 83 is then retained in position as shown in Figure 18 so'that when an operator grasps the forms extending above the roller 83 they can be pulled forwardly to sever the forms from the webs, the upper roll 83 moving upwardly to prevent binding of the forms between the rollers 8| and 82.

The carbon feeding mechanism consists of a roller 96 bearinged in a U-shaped support bracket 91 which is secured to the under side of the upper bed plate portion 34. The surface of the roller 96 is positioned adjacent an opening 98 provided in th uppermost edge of the bed plate 34 which is adapted to be engaged by a paper web for retating the roller 96 when the web is moved inwardly into engagement with the roller 96 by means of a roller I32. The roller 96 has a spur gear 99 secured upon the same shaft which bearings the roller 96, the spur gear 99 thu rotates with the roller 96. The spur gear 99 is in meshing relationship with a spur gear I bearinged in the support bracket 91 by means of the shaft IN. The gear I00 carries a pin I02 adapted to engage an arm I03 carried upon a shaft I04. The shaft I04 (see Figure 3) is bearinged at its 'inner end upon the shaft IOI which extends within an axle bore provided in theshaft I04. The opposite end of the shaft I04 extends within an adjusting mechanism for regulating the operation of the carbon feed in accordance with the length of form being used upon the same, which mechanism will be hereinafter described. The arm I03 is secured to the shaft I04 by means of a clamp I05 and is thus stationary with respect to the gears I00 unless rotated by th shaft I04. A torsion spring I06 surrounds the shaft IN and has one end thereof in engagement with the support bracket 91 and the opposite end secured to the gear I00 whereby the gear is constantly urged in a direction to place the pin I02 against the arm I03.

A carbon detent I01 is secured .adiacent each end of a rod I08 bearinged in the depending wall 09 of the upper bed portion 34. The carbon detents I01 are secured to the rod I08 by means of clamps I I0. The detents I01 extend through slots III provided in the upper bed portion 34 whereby the ears II2 are adapted to be engaged by carbon bars II3 (see Figures 6 to 10) which carry carbon sheets II4 adapted to be positioned between adjacent continuous paper webs. Each of the detents I01 carries a dog II5 pivoted thereto by means of a pin II6. A light spring is positioned between the dog H5 and the ear II1 extending upwardly from the detent I01 to urge the dog H5 in a forward position (as shown in Figure 4).

The carbon detent I01 has a ledge IIB adapted to engage a finger II9 provided'on a clamp I20 Secured to a rod I2I bearinged in the depending side wall I09 of the upper bed portion 34. The clamp I20 forms a lever extending from the rod I2I. A clamp I22 is secured to the'rod I2I from a lever extending therefrom adapted to be enaged by the pin I02 secured to the" spur gear I00. The clamps I20 and I22 provide a lever system between the pin I02 and the carbon detent I01 whereby the carbon detent is released when the pin I02 engages the clamp I22 to cause rotation of clamp I20 with respect to the carbon detent I01.

The shaft I08 to which the carbon detent l01 is secured has a clamp I23 secured thereto forming a lever extending therefrom. The clamp 1123 has .an arm I26 pivotally connected thereto by means of a pin I25 which extends into engagement with a. clamp I26, the lever I24 being pivoted to the clamp I26 by means of the pin I21 (see Figure 5). The clamp I26 is carried upon an arm I28 extending inwardly from a wire frame I29. The clamp I26 in this instance remains sufficiently loose upon the arm I28 to be bearinged thereon. A clamp I30 is secured to the arm I23 of the frame I29 and has a pin I3! extending therefrom into engagement with the bearinged I clamp I26.

The frame I29 carries a roller I32 positioned in substantially vertical alignment with the roller 96 to apply friction upon a paper web passing between the rollers I32 and 96. The Weight of the roller I32 and th frame I29 is such that the pin I3I normally engages the bearinged clamp I26 so that the clamps I26 and I30 actuate the frame I29 as though the arm I24 was connected directly to the frame I29 for rotating the same about the arm I28 as an axis.

If, however, it is desired to prevent the roller I32 from engaging the paper web, the mechanical arrangement provided by the clamps I26 and I30 permit the frame I29 to be moved rearwardly manually with respect to the operating mechanism. A stop I33 pivoted upon a support member I34 by means of a pin I34a (see Figure 4) is thrown rearwardly to permit the frame I29 to pass thereover and thus be thrown away from engagement with the paper web passing over the roller 96.

The support member I34 is adapted to engage the edge of paper webs passin over the bed portion 34 to maintain edge alignment between the webs. These support members-I34 are adjustable transversely of the bed portion 34 within slots I53 provided in the bed portion 34. J

When paper webs, which have been folded in accordion fashion, are passed over the upper edge of the bed plate 34, there is a tendency for the 'ation of the apparatus.

folds in the webs to cause the roller L32 to lift sufficiently that slippage is permitted between the roller 96 and the paper webs whereby the measuring device is not properly operated. To maintain the roller I32 in engagement with the paper webs alocking mechanism is provided for engaging the operating mechanism for the roller I32 when the paper webs are moving in engagement with the roller 96. When the paper'webs are moving over the roller 96 the position of the carbon feeding apparatus is as shown in Figures 4 and 8. 7

The locking mechanism for the roller I32 consists of an arcuately shaped arm I35 secured to a clamp member I36 which in turn is secured to the shaft I M (see Figures 11 and 12) The frame I29 carries a clamp I31 secured thereto and having a pin I36 extending therefrom. 'Thearm I35 has a hook I39 adapted to engage, the pin I38 to retain the frame I29 in position with the roller I32 in engagement with the paper web passing over the roller 96. The arm I35 is rotated with the shaft I2I as the axis of rotation so that when .the shaft I2 I rotates to position the carbon detent I01 in the position shown in Figures 1 and 7, the roller I32 is thereby placed in engagement with the paper webs passing over the ro1ler-96, causing them to engage the. roller 96 to drive the same, thehoolr I39 lieing advanced into engagement with the pin I36 thereby locking the frame I29 in position with the roller I32 engaging the paper web.

To manually release the locking mechanism (shown in Figures 11 and 12) a finger pad I40 is provided on the arm I35. By applying pressure, upon the iln'gerpad I40 the shaft I2I will be rotated about its axis in a rightward direction (as viewed in Figures 11 and 12) to release the pin I25 and thereby permit the roller I32 to be lifted from the paper webs.

The description heretofore presented sets forth the mechanical arrangement of the carbon feeding apparatus. The diagrammatic figures, 6 to 10, show the apparatus in various stages of operation. The mechanism is shown in various positions resulting from various movements and oper- The mechanism shown in these figures is somewhat schematic but-the operational function is completely set forth.

Beginning with Figure 6, the apparatus is shown in a position wherein a typing operation can be performed upon a plurality of adjacent. paper webs I42, I 43 and I 44 having carbon sheets II4 interleaved therebetween. The carbon sheets 4 in this figure are shown in position for the typing operation and have been previously released from the carbon detent I01 to permit the carbon bars H3 and the carbon sheets 4' to move with the paper webs I42, I43 and I44, as fed through the typewriter by means of pressure engagement between the'platen I3 and the prescarbon detent I01 is rotated about .the axis ofthe shaft I03, and since the detent I01 issecured to the shaft I03 the clamp I23 is rotated in the direction of the arrow shown in Fi ure '1. The ear 2 of the carbon detent I01 rises into the position shown in Figure I to positionits'elf in the path of the downward travel of the carbon bars II3 when their travel is reversed by reversing rotation of the platen I3. Rotation of the clamp I23 positions the arm I24 to cause rotation of the frame I29 in the direction of the arrow shown in Figure 7 whereby the roller I32 is caused to engage the paper webs, I42, I43 and I44 and move them into engagement with the roller96,

As can be seen from the position of the linkage between the shaft I06 and the frame I29 a toggle arrangement'is provided thereby so that when the apparatus is in the position shown in Figure 7 there is a tendency for the carbon-detent I01 to be retained in the position shown .therein.

When the carbon detent I01 reaches the position shown in Figure 7 the lever linkage providedby'the clamps I20 and I22 on the shaft I2I tends to rotate in a rightward direction; as indicated by the arrow, due to the oil-balance of the linkage in that direction whereby the finger II9 provided on the clamp I20 is positioned beneath the ledge IIB provided on the carbon detent I01 to lock the detent in the position shown in Figure 7. Also, the arm I35 engages the pin I36 as shown in Figure 12 to lock theroller I32 in position as shown in Figures 7 and 12.

The paper webs are moved rearwardly or upwardly along the bed plate 33 until the above described operation is performed. If the operator of the typewriter should run the typed form from between the platen I3 and the pressure rollers I a slight buckle will be given the paper webs (as shown at I54) to provide suiiicient spring I the finger us on the clamp in engagement with the ledge II6 on the carbon de- 7 of paper web passing over in the webs to force the ends thereof into engagement with the platen I3 and the pressure roller I so that when the direction of rotation of the platen I3 is reversed the paper webs will be caught between the platen I3 and the pressure roller I to again send the same through the typewriter.

The mechanism is now in position to permit passage of the paper webs I42, I43 and I 44 over the bed plate 33 without movement of the carbon sheets II4 so that the form which has been previously typed can be removed from the typewriter and a subsequent form aligned. The beginning of this operation is shown in Figure 8. The showing of this figure is such that the platen I3 is rotating in the-direction of the arrow, thereby moving the paper webs I42, I43 and I44 through the typewriter, but the carbon sheets I I4 are detained from movement since the carbon bars II3 are in engagement with the ear II2 of the carbon detent I01. It will be remembered that the roller I32 is in engagement with the paper webs passing over the roller 96 so-that the roller 96 will be rotated by movement of th paper thereover, due t the frictional engagement of the paper webs with the roller 96. Rotation of the roller 96 causes the gear I00 to be rotated so that the pin I02 will be advanced in a leftward direction, as indicated by the arrow in Figure 8. The pin 102 would be advanced and the clamp I20 in a leftward direction until tent I01. The quantity the roller .96 before the'carbon detent I01 releases the carbon bars travel of the pin .Il2 from the arm I03 to the until it strikes the end of the-clamp I 22 rotating the shaft I2I is. moved out of I is equal-to the length of a printed form face and is measured, by the clamp I22. The interval of time required for the pin to move from the arm I03 to the clamp I22 and release the detent I01 thus regulates the length of paper web moved through the carbon sheets I I4 before they are released to permit their movement with the paper webs I42, I43 and I.

Movement of the paper webs I42, I43 and I over the carbon sheets III and the carbon bars H3 produces friction tending to move the carbon bars downwardly and thus move the carbon sheets with the paper webs. However, the carbon bars cannot move until the pin I02 has engaged the clamp I22 and has rotated the clamp I20 suificient to release the carbon detent I01. When the carbon detent It? is released, frictional engagement between the paper webs and the carbon sheets will rotate the carbon detent I01 about the axis of the shaft I08 thereby causing movement of the arm I24 which results in lifting the roller I32 from engagement with the paper webs passing over the roller 96. Release of pressure upon the paper webs passing over the rollerv 96 stops rotation of the roller 96 since the webs are released from engagement with the surface of the rollerand will now be supported by the bed plate 3t spaced relationship to the roller 96. The linkage between the carbon 'detent m and the frame I29 is such that the combined weight of the roller I32 and the frame I29 retains the mechanism in the position shown in Figure 9 since the arm I24 and the clamp I23 have now been thrown over center from the position shown in Figure 8.

When the pressure is released from the paper webs the torsion spring I rotates the gear I00 to return the pin I02 against the arm I03 so that the measuring device is conditioned for the next operation.

The carbon sheets and the paper webs are now ready for advancement through the typewriter by means of the platen I3 and the pressure rollers III to permit the typed form to be removed from the machine, to ali a subsequent form and to position the subsequent form in typing position upon the platen I3. The transition from Figure 9 to Figure showsthe paper webs advanced through the typewriter until a perforation or fold line between adjacent forms is adjacent the tear off blade 83. The operator rotates the platen I3 until a perforation or fold line is aligned with the pointer I16. This places a. fold or perforation line adjacent the blade 83 as shown in Figure I6. At this time the pressure rollers I lI of the typewriter are released from engagement with the paper webs passing under the platen I3. The blade 83 is then moved inwardly to engage the webs and align them. This is accomplished since the fold line between adjacent form faces is the weakest portion of the form and the adjacent folds will always tend to align one with the other when a shart edged instrument engages the fold line and moves thew.v

same thereby.

arm I03 with respect to the clamp I22, andthus the travel of the pin I02 regulates the length of paper web which passes between the carbon sheets III before they are again released to permit their advancement with the paper webs. To adjust the position of the arm I03 the mechanism shown in Figure 13 is provided.

This mechanism consists of a worm wheel I45 secured upon the shaft I00 which carries the arm I03 (as shown in Figure 3). The worm wheel I05 carries a pointer I40 having an edge thereof adjacent a slot IA'I provided in the cover I48 for the adjusting mechanism. A worm I09 is in engagement with the worm wheel I05 and is carried upon a shaft I50 bearinged in the cover I48. A hand wheel I5I is secured to the shaft I50 and is disposed beneath an indicating pointer I52. Indices are placed upon the hand wheel I5I indicating fractions of an inch so that one rotation of the hand wheel I5I causes rotation of the shaft I04 to position the arm I03 further from or closer to the clamp I22 to shorten or lengthen the form passing over the roller 95 before release of the carbon detent I01. One rotation of the wheel I5I thus changes the setting of the arm I03 to permit-one inch more or one inch less of web to pass over the roller 96 until the carbon bars are released.

Rotation of the worm wheel I moves the pointer I45 to indicate the number of revolutions of the hand wheel I5I and thus the number of inches which can pass over the wheel 98 before the carbon detent NI releases the carbon bars H3. The indices adjacent the slot It! thus indicate inches in length of the paper web so that by reading a combination of the indices adjacent the slot I41 and the indices on the hand wheel I5I an exact determination can be had of the length of form for which the carbon feeding mechanism is set.

In order to use the typewriter in normal typing operation for single sheet work the frame 60 can be pivoted upwardly upon the pins 83 and 60 so that the frame will lie upon the bed plate 53. The paper bale 88 is removed from the carbon feeding apparatus to permit the pivotal movement of the frame 60. The paper guide 53 is then moved upwardly until the rolled edge 54 engages the hook portion 56 of the retaining member 55. When these operations have been performed the space above the typewriter platen I3 and the back plate 51 of the typewriter is free and unobstructed so that paper sheets can be fed into the typewriter in the normal manner.
