.10 the pending application of David W. Rubidge,

Serial No. 407,251, filed November 14, 1929 (now Patent No. 1,896,465 dated February 7, 1933) In certain typewriters of this kind, individual carbon-sheets are held at one end in blades, and

together with said blades are inserted between the work-web plies, the blades being attached to a carbon-carriage, mounted for movement toward and from the platen. By means of this carriage and the attached blades, the interleaved carbon-sheets can be retracted to register with a fresh work-web form every time the typing on one form is completed; it being understood that the carbon-carriage carrying the aforesaid blades and carbon-sheets will have advanced with the work-web in linefeed movement toward the platen during said typing. L

In certain other kinds of manifolding typewriters, continuous rolls of carbons areemployed, instead of the comparatively sh'ort aforesaid carbon-sheets, the carbon-rolls being mounted in the carbon-carriage. The axes of the rolls are spaced laterally from the edges of the work-web, so that the rolled portions clear said web. A suitable length is unwound from the carbon roll, is carried transversely across the web, and is then turned over a dfagonal guide disposed in the path of the web. By such turning the carbon is directed along the web toward the platen, enough carbon being unwound to suffice for manifolding without interfering with said-diagonal guide.

Owing to the difference between the substantial width of the carbon-rolls and the much narrower width occupied by the aforesaid blades, a carriage for the rolls takes up more room in the direction of carriage movement than does a carr'iage for the blades.

hon-carriage moves, and thereby accommodate the wider carbon-roll carriage'without reducing its range of movement. In other cases where a Wide carbon-roll carriage was used in a machine having guides of a length designed for a narrower blade-carriage, the range within which such wide carriage could move was reduced, owing to the heretofore used arrangement of the carriage rela- Heretofore it has been the practice to extend the guides upon which the cartively to its guides. Such reduction of the carriage-movement range resulted in a corresponding; limitation of the length of form which could be manifolded without shifting the carbons.

- A feature of the present invention an ar-' 69 rangement 'for a carbon-carriage for widecarbun-rolls whereby a typewriter havingguides designed for a narrow blade-carriage may, without change, receive the wider carbon-roll carriage without reducing the efiective range of 5 carbon-carriage movement, that is to say, just as long a'form may be manifolded with the wider carriage as was manifolded with the shorter carriage.

The importance of this feature resides not only 70. in the possibility which it affords of applying wide carbon-roll carriages to guides that were, designed for the narrower carriages; but there is also the advantage resulting from the weight of the typewriter-platen-carriage being kept down, it being understood that the guides for the carbon-carriage are directly connected to the typewriter-platen-carriage, and that any extension or such guides increases said weight. Furthermore such increase in length and weight is at a point remote from the main typewriter-carriage-- guides and escapement-mechanism, and inits skewing efiect every time the carriage is arrested the increased weight puts additional strain on said bearings and mechanism and is to be strictly avoided. V

The carriage includes a narrow truck which, in the illustrated embodiment of the invention, may accommodate different carbon-carriers. In the wide carrier the necessary width to accommodate the carbon-rolls and guides is obtained by extending said carrier so that when mounted upon said truck, it overhangs the rear of saidv truck. In this way the guide-rail length is minimizedand the weight of the complete typewriter-carriage is kept down.

Another feature of improvement relates to the diagonal carbon-guides. Heretofore, a number of vertically-spaced rods, separate from the diagonal guides and extending transversely of the composite work-web could be prepared.

According to the present invention, these verable in said carriage. To these ends,.each diag' onal guide may include one of the aforesaid rockshafts which also serve to space a carbon-sheet vertically.

An angularly-shaped wire or member is used and includes two portions, one portion forming the diagonal guide and being secured to one end of the rock-shaft, and the other portion formin a strut supporting the other end of the diagonal portion and being secured to the rock-shaft at a point spaced from the point where the diagonalportion is secured to said shaft. There is thus formed a triangle having a rock-shaft, the diagonal portion and the strut-portion as its sides. iihe rock-shaft extends sufficiently beyond the triangle thus formed, so that it may be journaled in supports, each support including a series of vertically-spaced bearings, which, in conjimction with novel formations on the ends of a rock-shaft, facilitate easy removal and replacement of the triangular diagonal guide. The preferred procedure for assembling a workweb with its interleaved carbons is to remove all the triangular guides from the carbon-carriage and then replace them seriatim, as one after another of the carbon-sheets is withdrawn from itsroll and threaded around a guide. Thus,beginning with the first carbon-sheet for the lowermost plies, the leadingedge of said sheet is drawn slightly past the rock-shaft position, the rockshaft with its attached diagonal guide is then inserted in its bearings, the rock-shaft overlying the sheet, and the sheet is then further pulled forward, turned over said diagonal guide for direction lengthwise of the work-web and carried a suitable distance past said guide. While said sheet is being thus threaded around the guide, the latter may be swung to any convenient position away from the web to facilitate such threading, and the subsequent insertion between corresponding plies of a work-sheet. The next diagonal guide for the next ply is then picked up and inserted into the carriage, the carbon-sheet associated, with said guide being then similarly threaded therearound and inserted between its corresponding plies of work-web. v

The built-up assembly of rock-shafts thus formed separates and directs the several carbonsheets, the separation being effected without the necessity of threading the leading ends of the carbon-sheets into the narrow openings of the vertically-spaced rock-shafts.-

Other features and advantages will hereinafter appear.

The invention is herein illustrated in connec-" tion with a fan-fold typewriter of the kind shown in the patent to Wernery & Smith, 1,132,055, dated March 16, 1915, in which a platen-carriage includes a frame 20, Figure 2,'guided for letter: feed travel on a front rail (not'shown) and a rear rail 21, supported by posts 22 of thetypewriterframe. In said carriage-frame, a platen 23 is mounted on a platen-axle 24, journaled in end plates 25, attached to a cross-shaft 26 for swing- 7 shifted, inasmuch as, in vsaid displaced position,

the tortuous course which the web assumes when the platen is in its normal position is straightened out, as fully set forth in said patent.

From a suitable position behind the typewriter, the web may be guided over a cross-member 28 of the novel carbon-carriage, and in a manner and by means to be described, the. plies of said web will have been interleaved with carbonsheets when the web and platen are in writing position.

To facilitatereplacement of worn carbon-sheet portions, said sheets are in the form of rolls 30, from which fresh portions may be unwound. Each roll may be made up of a number of superposed sheets, and the rolls may be arranged at the sides of the'work-web, the axes of the rolls return directions.

1 extending parallel to the path of the work-web, seeFigur'es 1 and 3. F

A suitable length of carbon-sheet'is led from a roll in a direction crosswise of the work-web, and is turned, over diagonal guides to be described, in the direction of the work-web. The carbon-rolls and carbon-sheet guides are supported in a movable and novel carbon-carriage, so thatthe interleaved carbons may, bymeans of said carriage, move as usual with the workweb, as the latter is line-fed, and, furthermore, so that the interleaved carbon-sheets may be re- 6 tracted to register with a new work-webform after-typing on thepreceding form has been completed.

For supporting and guiding the carbon-carriage, which, inasmuch as it carries the composite work-web, must also move with the platencarriage' in letter-feed and return directions, there is projected, rearwardly from said platencarriage, a pair of guide-rails 31. At their rear ends, said rails 31 are spaced and connected by a cross-member 32, to form a frame which, by

means of 'Lpivoted connections 29, located at the forward ends of said rails 31, is secured to brackets 33 fastened to and extending rearwardly from the platen-carriage frame,20. The typewriterfrainework also includes a stationary cross-rail 34 for supporting the guide-rails 31, and along which cross-rail 34 said guide rails 31 may move as the platen-carriage moves in letter-feed and For bearing upon said crossrail, each guide-rail 31 has-a roll 35 mounted on a bracket 36 secured to the guide-rail, said bracket including a horizontal tab 37, which, bearing against the under side of the cross-rail 34, prevents upward displacement of the guide-rail.

two guide-rails 31.

As it is desirable, .on occasion, to replace one carbon-carrier by another, the guide-rails 31 support a truck 38, to which difierent carbonthe present invention includes a base 43 formed of sheet-metal, and 'having its edges turned down, as at 44, to secure stiffness of the base. The base 43 rests upon the truck-plate 39, and, to this end, it may be provided on its under side with elongate bosses 45 extending crosswise of the base 43, as shown in Figure 2. As best seen in Figure 3, said bosses 45 may be pressed out of the sheet-metal forming the base 43. Extending downwardly from said bosses '45, tobe received by corresponding openings in the truckplate 39, are the usual slotted pegs 46, said pegs 46 having slots to receive the edges of holding levers 47, pivoted on studs '77 on the under side of the truck-plate 39, as best seen in Figure 3. The pegs 46 are secured to the base 43, by riveting, washers 48 being interposed between the riveted ends of the pegs and base 43 to thereby hold the pegs securely. It willbe evident from said Figure 3 that, with the levers 4'7 in the position shown, the base 43 of the carbon-carrier is secured to the top of the truck-plate 39,. It, will also be evident that, if 'the levers 47 are swung outwardly about said studs 77, that is, away from the pegs 46, the edges of said levers will be withdrawn from the slots in the pegs 46 and the base 43 and the pafis carried thereon to form a carbon-carrier may then be removed. Other carbon-carriers that are to be used with the truck 33 will have similar pegs 46. As shown in Figure 2, the turned-down edges 44 of the base 43 may embrace the front and rear edges of the truck-plate 39.

Retaining. brackets 49' for the carbon-rolls and carbon-guides are mounted on the carbon-carrier base 43, and are designed to secure lightness without sacrificing strength. With a fan- ,folded web, it is necessary to be able to insert carbons from'either side of the web; one of the novel brackets 49 is therefore mounted upon the base 43, upon each side of the web. Each bracket 49 may include an elongate base-portion 50, having turned edge-portions 52 to secure stiffness. Said base-portion 50 may also be provided with openings 51 to secure lightness. For attachment to the base 43, the turned edge-portions 52 of saidbase 50 may be extended to form feet 53, by means of which the bracket 49 may be secured to the base 43 by screws 54. Turned up from the endsc of the base-portion 50, and integral therewith, are portions forming supports 55 and 56, in which. carbon-roll spindles 5'7 and rockshafts 58 may be retained, said rock-shafts 58 forming part of the novel diagonal guides to be described later herein. The length of the bracketbase 50 is such that the spacing of the upturned ends 55, 56 is large enough to include'a sufficiently wide carbon-roll 30.

The invention is herein illustrated as bodied in a machine-employing four carbon-rolls, two on each side of the work-web; it being understood, however, that the invention is not limited to any specific number of rolls. a The carbonrolls are wound on spools 59. Each spool may have a rectangular opening 60 extending centrally throughout the length of the spool, which.

opening, as best seen in Figure 12, may at one end of the spool fit over a similar rectangularly shaped hub 61 of a cup-shaped member 62, which may form a retaining flange to abut one end of said spool. The other endof the spool is also provided with a retaining flange 63 having an outer hub 64 and an inner cylindrical hub 65; which latter hub is of a diameter to fit into the opening 60 of the spool. The flange 62 may be keyed to the carbon roll spindle by a pin 67. The flange 63 is slidable along the spindle 5'7 to alter the spacing between the flanges, so that different widths of carbon-roll may be accommodated, and said flange 63 may be secured by a set-screw 66 threaded into the outer flange 64 and binding on the spindle 57. An extra flange ll2-is for use with narrow spools as will be explained later herein.

The cup-shaped flange 62 has, as best shown in Figures 7 and 8, V-shaped teeth 68 cut in its rim-edge and thereby forming a crownshaped detent-wheel that co-operates with other parts to lock the spool in a manner to be dewith notches 75, each to receive the reduced portion at the other .end of said spindle. A'latchplate '70, common to the two spindles 57 that notches '75, when the latch, urged by a spring '74, is

' eluded. Such rearward extension is substan-- in the position shown in Figure 1.

When the latch-plate '70 is moved in the direction of the arrow (Figure 1), the hooked portions '73 thereof will be withdrawn from the spindles 5'7, and either spindle may then be lifted out. The upper ends of the hooked portions '73 and also the sides of the notches '75 may be formed so that a spindle 5'7 may be snapped into place by laying the end of said spindle against said upper portion of the hook '73 and notch-side and pressing down the other end oi the spindle having first been inserted in its hole '76 in the opposite support 56' Such pressure will cause the spring '74 to yield-and the latch-plate '70 to be displaced, the latch, urged by the spring 74, snapping back into place as the end of the spindle seats itself under said pressure in the notch '75.

As seen in Figure.2, the extent of the truck 38 in the direction of the guide-rails is substantially less than the extent of the carbon-carrier mounted thereon. Said truck 38 would also accommodate a narrower carbon-carrier of the type set forth in the aforesaid Wernery & Smith patent. According to the present invention, the carboncarrier is extended toward the rear of the machine, to aflord sufficient room within which the wide carbon-rolls and carbon-guide may be intially beyond the rear side of the truck 38. The rearward extension of the carbon-carrier will therefore overhang the rear endsof the carboncarriage guide-rails 31 when said truck is pushed back to the ends of said rails 31.

For turning the carbon-sheets from the direction crosswise of the work-web as they are unrolled from the carbon-rolls into a direction along the work-web, there are provided diagonal guides 80, secured to the aforesaid rock-shafts 58 in a manner best seen in Figure 5. As will be seen in said Figure 5, each diagonal guide is one of two portions of an a'ngularly bent wire, the other portion forming a strut 81, to support the free end of the diagonal guide 80, As seen in Figure 5, the other end of the diagonal guide 80 andone end of the strut 81 are inserted in drillholes 82 of said rock-shaft and firmly held in said holes by any suitable means, as, for example, a forced fit, soldering or riveting. The diagonal guide 80, rock-shaft 58 and strut 81 form a triangular carbon-guide. The rock-shaft 58 is extended sufficiently beyond the diagonal guide 80 and strut 81, so that it may be journaled in the supports 55, 56, which form part of the bracket 49. An object of the invention is to make said triangular carbon-guides easily removable ,from and replaceable in the supports 55, 56. To this end, one end of each rock-shaft may be cham- 'fered and rounded, as at 84, Figure 5, to facilitate insertion into one of bearing-holes 85 of the sup.- port 55. Said bearing-holes 85 may be sufliciently larger in diameter than the diameter of a rock-shaft 58, to permit the rock-shaft to be skewed, so that the other end'of said rock-shaft may be passed around the inner surface of the opposite support 56, for insertion into or withdrawal from one of the bearing-holes 86 in support 56 for said other end of the rock-shaft. Said bearing-holes 86 are formed to include slots 87 through which a flattened head 88 of the rockshaft may be inserted. Adjacent said flattened head 88 is a cylindrical neck 89, smaller in di ameter than the body of the rock-shaft, which is journaled in the cylindrical portion of the hole 86. As seen in Figure 5, it is evident that after insertion of the rock-shaft end, including the flattened head 88 and neck 89, into a hole 86, 87, and, after said rock-shaft has been given a quarter turn, said end of said rock-shaft will be interlocked with the support 56, as indicated at 90. Preparatory to assembling a web interleaved with carbon-sheets, all of the r0ck-shafts 58 and attached guides 80 are removed from the carboncarrier and laid aside, ready for use. Sufiicient lengths of carbon-sheets are unrolled and allowed to hang idly, as shown, for example, at 91, Figure 13. Said Figure 13 shows a number of plies 92 of the work-web already, interleaved with carbonsheets 93. During such interleavement, the guides 58, 80 were introduced into the carboncarriage, one after the other. For example, the lower carbon-sheet 93, as shown in Figure 1, will have been picked up first and its leading edge advanced slightly beyond the position to be occupied by the rock-shaft 58. Said rock-shaft 58 will then have been picked up, placed over the carbon-sheet so advanced, and at the same time will have beeen inserted in its bearings in the supports 55, 56. With the rock-shaft 58 turned so as to elevate the diagonal guide 80 to the position illustrated at 80, Figure 13, the leading edge of the carbon-sheet is then advanced further,

web, it is next in order to introduce the lowermost carbon-sheet coming from the right of the workweb. In the latter case, the leading edge of the carbon-sheet is also advanced to a position ,just beyond that which the rock-shaft will occupy,

said rock-shaft and its attached diagonal guide 80 being then inserted in its supports 55, 56, the carbon-sheet being then advanced and turned about the diagonal guide 80, which, together with the carbon turned thereabout, is then swung downwardly against the next ply, of the workweb. If the web is fan-folded, as shown in Figure 13, the carbon-sheets are thus built up alternately bon-rolls and the edges of the work-web. It has not been necessary to insert the leading edge of every carbon-sheet into the narrow opening between any of the two rock-shafts 58, inasmuch assaid rods and their attached guides were assembled seriatim, that is to say, in the case of two adjacent rock-shafts 58, the lower rock-shaft 58 was first in place, then the carbon-sheet laid over it, and on top of that the next rock-shaft 58, and so on, until the assembly was built up.

, While the carbon-sheets are being interleaved with the several plies of the work-web, the leading ing lever 98.

enses edge of said web may be slightly in advance of. the diagonal guides, that is,.in advance of the struts 81 of said guides. Similarly, the leading edges of the carbon-sheets may also extend beyond the struts 81, but preferably not quite as far as the leading edges of said plies. The work-sheet plies and carbons interleaved therebetween are then advanced toward the platen and threaded around said platen while the carbon-carrier is held, the

carbon-rolls turning as the interleaved carbonsheets together with work-web plies are so advanced. It will be understood that during this operation, the platenis in the position shown by the broken lines in Figure 2. Ihe platen is then lowered to its normal writing position, and the carbon-carrier may be retracted far enough to afiord a sufficient range of advance for line-teeding. During such retraction, the carbons, if the platen is in its writing position, will be held by said platen, and it is necessary, therefore, that the carbon-rolls be free to revolve. During the regular line-feeding advance of the carbon-carrier, however, the carbon-carrying rolls must be locked, and the parts that cooperate with the r previously mentioned detent-member teeth 68 to leg abutting said support 56, and the other leg extending from said support, and carrying the lever 98, which is pivoted on a stud 101, carried by said latter leg. Said latter leg also carries a holding lever 102 for the locking lever 98, said holding lever being pivoted on a stud 103. For manipulation, the locking lever 98 has a finger-piece 104 extended to project through an opening 105 of the support 56. Furthermore, said locking lever 98 has an arm having a V-shaped edge 106 which may engage the detent-teeth 68 formed on the flange 62 of the carbon-rolls. and below said edge 106 is 'a shoulder 107, over which a latching portion 108 of the holding lever 102 may beinterposed, as. shown in Figure 8, when it is desired to keep the holding lever 98 withdrawn from the detent-flange teeth 68. The locking lever 98 and its holding lever 102 are connected by a spring 109 having points of attachment to said levers as seen inFigures 7 and 8. It will be seen from Figure 7 that the distance from the axis of said spring 109 to the center of the pivot-stud 101 is such that in conjunction with a suitable strength for said spring, the

V-shaped edge 106 of the locking lever 98 is firmly held against the detent-flange teeth 68, and that the .corresponding carbon-roll is thereby securely held against rotation. While the locking lever 98 is so held in its effective position, the axis or the spring 109 is suinciently near the center of the pivot-stud 103 of the holding lever 102th minimize the pressure of said lever 102 upon theloclr- When it is desired. to unlock the carbon-roll, the locking lever 98 is, by means of its finger-piece 104, shifted to the position indicated in Figure 8. spring 109 will have increased its distance from the pivot-stud 103 and decreased its'distance from the pivot-stud 101, with the result that, whereas the. turning power of said spring upon the holding lever-102 is increased, its turning power upon the locking lever 98 is decreased, and said spring, therefore, enables theholding lever 102 to hold Extended beyond In thisposition, the axis of thethe locking lever 98 in the position indicated in said Figure 8, in which the finger-piece 104 abuts the end of the opening 105. For restoring the locking -lever 98 to the detent-teeth 68, a pull upon the finger-piece 104 of said locking lever in the direction of the arrow. Figure 8, overcomes the tension of the spring 109. Inthis case the locking lever 98 is rotated clockwise-and causes the holding lever 102 to be displaced in counterclockwise rotation until its latching portion 108 escapes from the end of the shoulder 107 of the locking lever, whereupon the spring 109 will be effective to force'the t -shaped edge 106 of the locking lever into engagement with the detent-teeth 68 again.

Some worlowebs have plies of difierent widths as shown in Figure 9. in such case, narrow car hon-sheets 110 are used and are unwound from correspondingly narrow rolls 111. An extra flange 112 may be provided for the narrow roll ill. if it is at the left of the'web, it being inexpedient to move the flange 62 to abut the narrowroll 111, because said flange 62 carries the detent-teeth 68,

which, in the case where narrow-rolls are used,

also serve to lock said narrow rolls. Said extra flange 112 has a rectangular hub 118 (see Figure 12) to fit the opening 60 of the carbon-spool 59, the latter corresponding, of course, in length with the narrow roll. Said flange 112 also has an outer hub 114 in which is threaded a set-screw 115 to bind upon the shaft 5'2. When a narrow roll is used at the right of the web, the regular flange 63 is simply moved to abut said narrow roll, as shown in Figure 9. Figure 9 shows the use of a fan-fold form with wide folds and narrow folds. The narrow or bottom fold has to be slit by guide-rod 80, of the standard carbon-guide in order to pass said rod 80. The wide plies of the fan-fold form pass freely and unslit past the standard carbon-guides. Figure 9 thus shows an arrangement whereby the fan-fold form of wide and narrow plies can be used with standard size carbon-guides, by slitting the narrow folds. h

It will be seen in Figure 9 that the diagonal guide 80 crosses the folded edged the narrow web-plies when said guide 80 projects from the same side of the web at which the narrow plies are disposed. It is necessary, therefore, that such folded edge be cut as shown at 116. Such cutting may be done by moving the carbon-carrier backward while holding the whole web, in which case the guide 80 does the cutting, or the cut-' tingmay be effected by a separate operation in any suitable manner, as, for example, by running a knife down said folded edge. In some cases, however, where a webhaving plies of different widths is used, it is desirable to retain the plies in their fan-folded form after a form has been typed on and detached from the web. Figure 11 shows an arrangement whereby a fan-fold web of wide and narrow folds is used without slitting any of the folds. For this purpose a carbonguide having a short diagonal reach may be used for the narrow told, which freelypasses the short-reach carbon-guide without being slit. The short-diagonal reach carbon-guide is arranged to be mountable in the same supports as mount the standard carbon-guides so as to be interchangeable with the latter. By mounting thediagonal guides 80 on the rock-shafts 58, said guides maybe made of different lengths, for a web having fan-folded plies of difierent widths, the folds of which plies are not to be cut. As seen in Figure 11, a short diagonal guide 117 is fastened to a regular rock-shaft 58 in the same manner already described for fastening the longer guide- 80, such short diagonal guide 117. being employed wherever a carbon is .to be interleaved from the side of the web at which the narrow web-plies are to be disposed, that is to say, if the interleavement from such side of the web is to be between narrow plies, a short guide 11'? is used. If the interleavement is to be between full-width plies, a guide 80 of full length may be used. In any case, if the interleavement is from the other side of the web, guides 80v of full length may be used irrespective of whether such interleavement is between wide or narrow web-plies. The use of the short diagonal guides 117 also avoids the necessity for providing the extra flange 112 for the carbon-rolls at the left of the web, the regular flanges 63 being suitable, as will be evident from Figure 11.

Figure 10 illustrates how a diagonal guide may be extended beyond the folds of a fan-folded extends perpendicularly. to the rock-shaft .ets by screws 127.

web to out said folds, as indicated at 113. To afford suchgextension 119 of the diagonal guide without a corresponding increase of the length of the rock-shaft 58, on which such extended guide -80 is mounted, the wire forming said guide may have areverse bend at a point 120, which lies beyond the fanfolded edge. From said point 120 the wire may extend in a direct line to its point of attachment 121 with the rockshaft 58, or, as is preferable and illustrated, the wire may be bent and directed from said point 120 to include a bend 122, from which the wire 58 to its point of attachment 121.

The wire forming the diagonal guide 80 may also have a bend 123 just outside the edge of the carbon-sheet, the purpose of this bend being to incline the cutting portion or extension 119 of the diagonal guide more toward the folded edge of the web, and thereby facilitate the cutting of said edge.

For guiding the workweb laterally, there may be provided the usual guides 124, which are adjusted laterally of the work-web along the crossmember 28, which may be secured in brackets 126 extending from the rear end portions of the carbon-roll brackets 49, said brackets 126 being secured to the under side of said carbon-roll brack- Where a narrow carbonbracket is mounted on the truck 38, the cross member 28 may be retained in upstanding brackets 128 projecting from the rear portions of the carbon-rail frame along which the carbon-carriage mo'ves, said brackets being usually attached to the ends of the cross-,member 32 of said frame.- It will be noticed that the feet 5 3 of the carbonspool brackets 49 arehigh enough to elevate the base-portion 50 of said brackets 49 above said upstanding brackets 128, thus enabling said baseportion 50 to clear said brackets 128 or any rod that may span said brackets 123. s

The platen-carriage includes the usual papertable 129, a front paper-table 130 and a tie-rod 131 connecting end plates 132 of saidcarriage. Said tie-rod 131 also serves as an abutment for the end plates 25 of the swingable platen-frame. The usual gage 125 for. positioning the leading edge of the work-web, preparatory to detaching a finished form from said work-web, is fastened to the front paper-table. For moving the carhon-carriage back and forth conveniently from a position in front of the typewriter, there is provided an arm 135 formed as best seen in'Figures 1 and 2. For attachment to the right carbon-roll bracket 49, said arm may have an ear 136 abutting the upstanding carbon-roll support 56 of eluding a plurality of Said flat piece 133 forms part of a bracket 134, I

which is extended upwardly from the base 43 of the carbon-carrier, so that said fiat piece may support saidweb. The bottom ply of the web is in immediate contact with said flat piece 133, as seen in Figure 3, and the strut-portion 81, immediately above said bottom ply and resting thereon, cooperates with said flat piece 133 to support the web against sagging.

Figure 4 shows how two separate work-webs may be accommodated at one time by the carboncarrier, one of said webs being in use and the other one being idle. The leading end of the idle web may be tucked between two struts 81 of two diagonal guides, said two guides being inserted in the carbon-carrier in addition to the guides that are between the plies of the two separate webs.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
