TYPEWRITING MACHINE.

Continuation of application,

filed June 17, 1925. Serial No. 37,609. This application filed July 9, 1925.

Serial No. 42,382.

This invention relates to ty ewriting machines in which webs, usually firn-folded, are typed. These webs are printed with a succession of forms. and it is customary to 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 substrtute for my application, Serial No. 37,609, filed June 17, 1925.

An object of the invention is to provide a simple, inexpensive, light device for stripping the carbons, of such a character that the stripping device and the web-presenting devices 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 manifnlded, a difliculty 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 proto the plies of the web where they bend or loop around the platen. The carbons have the effect of one binding upon another as 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 dilficult 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 the composite web to be 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 tvping position. Such a device is disclosed in the U. S. patent to 'ernery & Smith. No. 1,132,055, dated March 16. 1915. This makes necetsary a substantial and expensive reconstruction of the typewriter-carriage and the platen-conneetions and also to provide expensive and bulky supporting frames and appurtenances.

It is one of the features of this invention to provide means for successfully stripping 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 under side of the platen from the typed form to the succeeding form. T 0 this end, each carbon is mounted upon an independently operable carrier. There are preferably as many carriers as there are carbons, an each carrier can move independently of all the others. It is within the scope of the invention, however, to attach two carbons to each independently movable carrier m some cases. After a f outermost carbon may be stripped it moves easily, has been shifted platen.

be stripped with the free all stripped.

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

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 suflicient to prohibit the stripping operation.

here may be a table or shelf extended upwardly and rearwaldly from the usual paper-shelf in rear of the typewriter platen, and the fan-fold web or loose web-plies may 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 one after another, beginning (outer) carbon, until they are ranged a set of tracks in the form of rods, fixed upon the platen carriage. preferably two rods for each 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 cars bored to fitupon the rod. so that it will slide easily. From each slide may extend to the right 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. which extends 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 oppositely-pointing blades being mounted thereon respectively.

It will be seen that at the completion of the typing operation. said slides or arms may be grasped by the operator one after another, and each one pushed upwardly along the papenshelf-extension or web-table as fa r as it will go, thereby stripping its carbon from the typed form. Preferably, the 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 stripped first, inasmuch as the outer carbons. not being taut, are not binding upon the inner carbon and do not snub nor seriously hinder its movement. It will 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 this 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 necessary to 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 platenframe, 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 carriermay 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 binding and tending to grip the inner earbons, so that the latter are not retracted first. The driving spring on the outer carbon-carrier is the first to complete the stripping of its carbon, because the same is not bound upon by other carbons. This makes the next carbon become the outer one, and, accordingly, its spring is effective next. Then the third carbon may be retracted by its spring. and so on, each carbon, upon bcing sufficiently released. being retracted. It 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 completed, and prior to the stripping of the carlrons, the composite wcb may be advanced and gagcd at the proper point for eventually tearing olt 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 prefautomatically erably the same length of stroke as the others. Before beginning the typing 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 earriers. 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.

The revoluble platen ll) of a standard Underwood typewriting 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 rearwardlvfrom the usual paper-shelf 1' 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 havin at its ends forwardly-projecting ears 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 alteration in the machine.

The fan-folded web is led down alone 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 deliver shelf 22 that extends upwardly and back from the platen; said delivery shelf having legs 23 whereby itis detaehably 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 usual in the well-known Underwood fan-fold typewriting machine; and each blade may be detachably held at 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-fold ing 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.

The carbon-carrying blades are fastened by said screws 27 upon individual heads 29, that are bent over upon 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 tit and slide upon a fixed rod 32, and each slide has at its lower end all car 33 bent oppositely from 30. to lit and slide upon a companion inner fixed rod or track 3 The parts are shown at Figures :2 and 5 in their rearmost positions. resting against adjustable stops 35. The steps are adjustable along the opposite edges of the webtable 14. which is provided with scales 36 for convenience in adjusting said stops, thus permitting the use of webs having dilferent lengths of printed forms. It will be seen that the carbon-blades 2:; are compact in their rcarmost positions at Figures 2 and 5, this compactness being permitted by the nesting of the slides 31, which are preferably divided into two groups. one group nested on the right hand rods 32. :24. and the other group nested on the left-hand rods 32. 34. 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 un der 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 limited to 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 tem orarily upon the top of the platen or elsewliere 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; the. feed-rolls being at this time cast: off.

The web may be advanced between the rolls and platen, and brought up to posit on in front of the platen to receive the first hue of typing. Then the feed-rolls maybe restored, and the typing may proceed line by line until the form is finished, whereupon the leading edge of the 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 and the platen onto the delivery shelf '22. Gage 39 is adjustable up and down the shelf 22. threaded apertures 39 being formed therein at spaced intervals for receiving a set screw 39" for holding it in position, which position is determined according to the length of the form on the web. Before tearing oti the web, however, the carbon-carriers should be retracted to the rcarmost position seen at Figures 2 and 5, together with the carbons. These carbon-carriers or strippers may be retracted one after another, by the use of linger-pieces -11 provided thereon, as illustrated for all six of the carbon-strippers at Figure 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 -11 and provided with springs 41", which operate their ends 11, 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 49. are preferably mounted upon a plate -13, 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 position to which the gage may be adjusted.

During the stripping of the web. that is, during the backward movement of 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 1-1, attached at their forward ends to the ears 33, 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 46, whereby all of the slides are held in lowermost positions against the tension of the returning springs 4-1. Said latches -16 may be carried upon a rock-shaft 47, pivoted at its ends in arms 48 bent back from the transverse bracket or bar 16. During this forward or downward movement of the stripping slides. the composite web is carried along by the blades 26, between which it is threaded; and an idle loop or slack 49 is formed 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 the line-spacing operations.

At the completion of the typing of any form. the platen is revolved to take up the remainder. if any, ot the loop 19, and to bring the leading end of the web up against the gage 3!). Then the clips =12 are thrust down to hold the web stationary against the web-table, and a finger-piece 50 upon the rock-shaft -17 is depressed to release the latches #16 and permit the individual springs 4% 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 1); and by reason of the pull of the springs 4-1 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 interferim with its free movement, so that it is carried back by its spring against stop 35. This outer carbon is connected to the carrier or stripper 31 which is most re mote from the platen, and, as shown, this is the right-hand strip )er, whose blade 26 overlies the blade of tlie rcarmost right-hand stripper. This rearrnost right-hand stripper is arrested by a stop 35. This relieves all tension upon said carbon, and hence all binding 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 nearestthe 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 40. 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 fingerpicces -11 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 46, which are held in latching positions by a spring 52, the latches yielding as the strippets are brought down. The springs may be made, if desired. too weak to strip the carbons, but capable of assisting the manual retraction of the carbon-Strippers one after another.

The invention is not limited to carbonstripping slides placed under the webtable,

ltlb

lit)

nor to carbon-strippers which are in the form of slides, nor is 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 the carriers that are nearest the platen, as at Figure 4. Preferably, however, they are connected to the most remote carriers, as at Figures 2 and 3.

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