This invention relates to'typewriting machines in which webs, usually't'an-folded, are typed. These webs are printed with a succession of forms, and it is customaryto employ manifolding material in the form of sheets of carbon which are stripped or shifted from each typed form to a succeeding form preparatory to typing the latter. This application is a continuation of and substi- 19 tute for my application, Serial No. 37,609,

filed June 17, 1925. I

An object of the invention is to provide a simple, inexpensive, light device for strip ping the carbons, of such a character that 1 5 the stripping device and the web-presenting fdevices can be attached directly to the typewriting machine, or to the carriage thereof, with little or no alteration therein, and may be simply, easily and rapidly manipulated. Where many copies are being manifolded,

a diificulty arises in round-platen typewriters, when it is necessary to strip the carbons from the typed form to the fresh form on the Web, because a snubbing effect is produced, and the carbons stick to the plies of the web where they bend or loop around the platen. The carbons have the effect of one binding upon anotherns it is attempted to pull them all back around the under side of the platen. This has not successfully been accomplished. If it is attempted to attach the carbons at their rear ends to a carrier, the carbons will prove diiiicult or impossible to strip or shift, and they would become torn. To avoid this obstacle, it. has

been the practice to displace the platen upwardly to permit thecomposite web tobe straightened out, and a carbon-carrier-has been provided which strips the carbons easily back to their new positions; whereupon the platen has been depressed to typing position. Such a device is disclosed in the U. S. patent to Vvlernery 8:- Smith, No. 1,132,055, dated March 16, 1915. This makes necessary a substantial and expensive reconstruction of the typewriter-carriage and the platen-con nections and also to provide expensive and bulky supporting framesand appurtenances. It is one of the features of this invention to provide means for successfully stripping all the others.

the carbons, as they stand looped around the platen at the.completion of the typing of a form, by merely pulling them back around the underside of the platen from the typed form to the succeeding. form. To this end, each carbon is mounted upon an independently operable carrier. There are preferably as many carriers as there are carbons, and each carrier can move independently of It is Within the scope of the invention, however, to attach two carbons to each independently movable carrier in some cases. After a form is typed, the outermost carbon may be stripped from the typed form and retracted to the next form, and therefore no longer binds upon the inner carbons. Said outer carbon strips easily and readily, because there is no carbon or sheet snubbing or binding thereon. Then the next outer carbon may be stripped from the typed form to the succeeding form, and it moves easily, because the outer carbon has been shifted back from around the platen. Then the third carbon may be shifted in like manner, and then the fourth, and so on; each carbon shifting, readily because it is not bound by any other carbon.

Itwill thus be seen that the carbons may be stripped one after another, beginning with the free (outer) carbon, until they are all stripped.

This overcomes the diiiiculty heretofore experienced of the snubbing or binding of taut carbons upon one another as it was attempted to pull them around the platen. 5 In the present invention there need be no binding and no diflicultyn.

If two adjacent carbons are attached to one carrier, they can in some cases be stripped successfully, because the binding of the outer upon the inner of the two carbons is not sufficient to prohibit the stripping operation.

There may be a table or shelf extended upwardly and rearwardly from the usual paper shcl't'. in rear of the typewriter platen, and the i'aniold web or loose web-plies may be led up over the top of this extension, and then downwardly over it to the intake side of the platen. Each carbon-carrier may comprise a blade or finger, which is thrust in between plies of web and carries a carbon, the fingers pointing alternately in opposite directions to accommodate the fanfolding of the web. Under the table may be ranged a set of tracks in the form of rods, fixed upon the laten carriage, preferably two rods for eaoi group of carbon-carriers, so that if there are two groups, there are four rods. Slides may travel up and down on the rods, each slide having at its ends ears bored to fit upon the rod, so that it will slide easil From each slide may extend to the rig t or left, as the case may be, an arm, said arm extending out beyond the side of the web-table and having at its outer end a head or mount upon which is fastened a carbon-carrying blade, whichextends from said mount inwardly to the plies of the web. In case it is desired to carry two carbons on one carrier, the slide may have two arms, one extending to the left and one extending to the right, and oppositelypointing blades being mounted thereon respectively.

It will be seen that at the completion of the t ping operation, said slides or arms may be grasped by the operator one after another, and each one pushed upwardly along the paper-shelf-extension or Web-table as far as it will go, thereby stripping its carbon from the typed form. Preferably, the v outer carbon is stripped first, but this may not be necessary in all cases, because it is evident that in manual operation the inner carbon can be strip ed first, inasmuch as the outer carbons, not heing taut, are not binding upon the inner carbon and do not snub nor seriously hinder its movement. It w1ll be understood that the usual feed-rolls are released which hold the composite web upon the bottom of the platen, so as to permit the stripping operation. It is practicable in thls manner to strip one carbon and possibly two at each movement.

Said frame and rods or tracks, and the slides or carriers thereon, are all that it is necessaryto add to an ordinary typewriting machine to convert it into a-fan-fold or other web-typing machine; a detachable delivery shelf being also added to the platen-frame, with gage, web-clip, etc.

If desired, each carbon-carrying blade may be provided with a knife to split the fold of the web at the operation of stripping the carbon.

In the preferred form of the invention, each carrier may be provided with an individual spring for effecting its carbonstripping movement. These springs may tend constantly to retract the carbons. The carbon-carriers may be latched in their advanced positions, and, upon being unlatched, their springs tend to pull all the carbons back around the platen, the outer carbons were binding and tending to grip the inner carbons, so that the latter are not retracted first. The driving spring on the; outer carhon-carrier is the first to complete the stripping of its carbon, because the same is not bound upon by other carbons. This makes.

retracted If the carbons are provided with web-splitting knives, the driving springs may be made of corresponding strength. The springs may be made weaker and serve only to assist the manual retraction of the carbons.

After the typing of each form is cont pleted, and prior to the stripping of the carbons, the composite web may be advanced and gaged at the proper point for eventually tearing 011' the typed form by means of a knife extending along the front upper side of the platen. The carbon-stripping occurs before the web is severed. The spring-retracted carbon-carriers may be arrested by .stops, which stops preferably are adjusted to vary the length of the strokes of the carbon-carriers. Each carbon-carrier has preferably the same length of stroke as the others. Before beginning thetyping of the next form, all of the carbon-carriers are preferably pulled downwardly and latched in their bottom positions, thus forming a loop of composite web between the carboncarriers and the platen, which loop is taken up at the line-spacing operations as the next form is typed. This makes it unnecessary for the platen and its feed-rolls to pull the composite web against the tension of a multiplicity of carbon-carrier-retracting springs, the aggregate tension of which is strong, especially where the springs must also split the webs when retracting the carriers. The track-rods are parallel with one another and mounted by their ends upon the web-table frame which forms an attachment that is secured upon the platen-carriage of the typewriting machine.

Other features and advantages will hereinafter appear.

This figure also shows the positions of the individual strippers at this time.

The revoluble platen 10 of a standard U11 derwood type'writing machine is mounted upon a platen-frame comprising'ends 11 and a paper-shelf 12 extending upwardly and rearwardly at the rear of the platen 10. A fan-fold web 13 is led upwardly from-a source of supply and then down over the rear or top edge 14 of a broad table, which extends upwardly and rearwardly from the usual paper-shelf 12. The lower or front end of said table is seen at 14 and it is supported by means of arms 15 extending rearwardly from a cross-bracket 16, the latter having at its ends forwardly-projectingears 17, whereby it is detachably secured upon the typewriter-carriage bar 18 by screws 19, such as are usually employed upon said bar in said machine; the web-table 13 and its appurtenances being preferably 'in the nature of an attachment to the standard typewriting machine, making unnecessary any J alteration in the machine.

The fan-folded web is led down along said table 14 and passes downwardly and forwardly between the platen and the papershelf 12, and is held and fed by the usual releasable feed-rolls 20, running upon the under side of the platen. The web is typed by means of the usual type-bars 21, and feeds upwardly "and rearwardly along a delivery shelf 22 that extends upwardly and back from the platen; said delivery shelf having legs 23 whereby it is detachably supported by screws 24 usually employed upon the platen-frame ends 11; said delivery shelf being also in the nature of an attachment.

Carbon-sheets 25, interleaved between the plies; of fan-fold web, are carried by blades 26, constructed as nsualin the well-known Underwood fan-fold typewritin machine;- and each blade may be detachably held ah one end, by means of a screw 27, upon a suitable support, the blades extending across the fan-fold web and pointing alternately right and left to accommodate the fan-folding of the web. Preferably, each blade carries a splitter 28 of usual construction, to split the folds of the web at the carbon-stripping operation. V

The carbon-carrying 'bladesare fastened by said screws27 uponindividual heads 29, that arebent over upoh arms 30, the latter extending to the right and left from slides or carriers 31. These slides are individual to the carbon-blades. Each slide arm 30 iS perforated to fit and slide upon a fixed'rod 32, and each slide has at its lower'end an ear bent oppositely from 30, to fit and slide upon a companion inner fixed rod 'or track 34. The parts are shown at Figures 2 and 5 in their rearmost positions, resting against adjustable stops 35. The stops are adjustable along'the opposite edges of the webtable 14, which is provided with scales 36 for convenience in adjusting said stops, thus per mitting the use of webs having different lengths of printed forms. It will' be seen that the carbon-blades 26 are compact in their rearmost positions at Figures 2 and 5, .this compactness being permitted by the nesting of the slides 31, which are prefer- -,ably divided into, two groups, one group nested on the right-

hand rods

32, 34, and the other group nested on the left-hand rods 32,

.84. The rods or tracks are riveted at their forward ends to the cross-bar 16 of the main bracket, and extend upwardly and rearwardly under the carbon-blades, and preferably under the web-table, and are supported at their rear ends in a flange 37 provided upon a plate 38, which is fixed to the rear or under side of the Web-table 14 at its upper end; said rods 32 being stationary, to guide the carbon slides or strippers.

The invention is not limitedto' a slide.

having a single carbon-carrier thereon, inasmuch as the arms 30 of any'slide or slides may,.if desired, be extended entirely across the work-web table, and may carry at their opposite ends carbon-blades 26, whereby two carbons may be controlled by each slide or stripper within the scope of the invention.

The inserting or loading of the carbons into the fan fold web may be done before the web is inserted around the platen, and while the carbon-slides are in'their rearmost positions; the web extending forwardly and resting temporarily upon the top of the platen or elsewhere. After the carbons are loaded into the web, in a manner known in this art, the leading end of the composite web may be thrust down between the paper-shelf 12 and the platen; thefeed-rolls being at this time castofii i i The web may be advanced between the rolls and platen, and brought up to position in-frontof the platen to receive the first line of typing. Then the feed-rolls may be restored, and the typing may proceed line by line until the form is finished, whereupon the leading edge ofthe web may be brought up against a gage 39 that is provided upon the'delivery shelf 22, at which time the web is in position to be eventually torn off by a transverse knife 40 ,which is mounted upon the platen-frame in front of the platen, the web having been delivered between the knife the transverse bracket or bar 16.

and the platen onto the delivery shelf 22.

Gage 39 is adjustable up and down the shelf carbons. These carbon-carriers or strippers may be retracted one after another, by the use of finger-pieces etl provided thereon, as illustrated for all six of the carbon-strippers at Figure 5. Preferably the upper outermost carbon is stripped or retracted first, and then the next inner carbon, and so on, although this order is not important in all cases, especially where no springs are used.

During the retraction or stripping of the carbons, which may take place before the web-severing operation, the web is preferably held by clips 42, which are mounted on pivots 41 and provided with springs ll", which operate their ends 41, so as'to pinch the sides of the web at its leading end against the delivery shelf 22, so that the web remains gaged until the carbon-stripping is finished; whereupon the web may be torn off against the knife 40. These web-detaining clips 42 are preferably mounted upon a plate 43, which carries the leading-edge gage, so that the clips may be adjusted with the gage, and be useful for clipping the web at the carbon-stripping operation in any po sition to which the gage may be adjusted.

During the stripping of the Web, that is, during the backward movementof the blades 26 along the web-table 14, the splitters 28 may be utilized to split the folds of the web, these splitters being individual to the slides 31, and the splitting operation being therefor rendered automatic and easy.

In the preferred form of the invention, the strippers are power-driven, or at least aided in their stripping action, as by means of draw-springs 44, attached at their for- Ward ends to the ears 38, and connected at their rear ends to the flange 37. In order to put the springs under tension, the uppermost finger-pieces 41 may be grasped and pulled downwardly along the web-table,

thus bringing down all the slides with their.

carbon-blades, until lugs 45 on the innermost or topmost slides 31 are caught by latches l6, whereby all of the slides are held in lowermost positions against the tension of the returning springs t-"i. Said latches 46 may be carried upon a rock-shaft 4T, pivoted at its ends in arms 48 bent back from During this forward or downward movement of the stripping slides, the composite web is carformed at the bottom of the Web-table, between the set of carbon-carriers and the platen, and below'the delivery shelf. During the subsequent line-spacing operations of the platen, this loop is gradually taken 'up; the strippers remaining stationary at web-table, and a finger-piece 50 upon. thev rock-shaft 47 is depressed to release the latches 46 and permit the individual springs as to strip the carbons. These springs put tension upon all the carbons, which at this time extends between the web-plies down around the under side of the platen and up in front thereof and up along the delivery shelf (Figure 4) and by reason of'the pull of the springs 44 the outer carbons tend to snub or bind the inner carbons around the platen and to interfere with or prevent the movement of the inner carbons; but the outermost carbon has nothing binding upon it, nor interfering with its free movement, so that it is carried back by its spring against stop This outer carbon is connected to the carrier or stripper 31 which is most remote from the platen, and, as shown, this is the right-hand stripper, whose blade 26 overlies the blade of the rearmost right-hand stripper. This rearmost right-hand stripper is arrested by a stop This relieves all tension upon said carbon, and hence all'bind ing upon the next inner carbon, which is thus free to be carried'back by its spring against the left-hand stop 35, which arrests the rearmost carbon-carrier at the left-hand side. This in turn relieves all binding upon the next inner carbon, and so on, until all the carbons are freed and restored. The innermost carbons at Figures 2 and 3 are connected to the stripper bars 26 that are nearest the platen and that are the last ones to be retracted. Then the clips are released, and the typed form is severed from the web by means of the knife -10. At this time the fresh, form, and also the leading ends of the carbons, are in position for beginning the first line of typing on the next form; but before typing said line, the topmost fingerpieces 41 may be grasped and pulled downwardly, thus carrying down both of the topmost or most remote slides or strippers, and with them the remainder of the set of slides, all of the slides being caught and retained by the single pair of automatic latches do, which are held in latching positions by a spring 52, the latches yielding as the strippers are brought down. The springs may be made, if desired, too weakto strip the carbons, but capable of assisting the manual 7 retraction of the carbon-strippers one after another.

The invention is not limited to carbon- 4 stripping slides placed under the Web-table,

nor to carbon strippers which are in the form of slides, nor the Web-table necessary in all instances; It is not necessary to use latches when no springs are used; and the outermost carbons may be connected to thecarriers that are nearest the-platen, as at Eigure 4,. Preterably, however, they are connected to the most remote carriers, as at Figures 2 and 3.

ItWill be seen that'the stripping movement between the. work-plies and carbon is effected by the movement of

truck

30, 31; and in order that the stripping may be eflected by moving this trucker carrier, there is provided' a co-operative clip 42, whereby the work-plies are releasably clipped at the leading end of the web. -The movement of the stripper-truck pulls the material around the platen while the webs are clipped, and the adjustable stop 35 terminates the stripping movement of the truck away from the platen. The stripping is efi'ected while the plies of the work-web extend around the platen.
