This invention relates to front-strike typewritin machines equipped for typing u on mul-tip e-ply webs, the same being either anfoldedy or consisting of loose plies.

These plies are usually interleaved with Jsheets of carbon, which are usually lon enough to cover only one 'or two forms. The carbons are stripped from each form after it vis typed, and .shifted to the succeeding form .on theweb; x I

1Where many copies are being manifolded, a difficulty arises in round-platen type writers, when it is desired tol stri the carbons from the typed 'forn to the resh formy on the web, because the carbone stick to the plies of web -wherethey bend around Pthe platen, a snubbing action taking place, that is, the car-bons having' the elfect of one binding upon another as it is attempted to pull them all back around the under side of the platen, asl by pushing back the carrier to which all the carbons are attached at their rear ends. The carbons are difficult to strip or shift, and are apt to become torn. To

Itis one of the features of this invention to provide meansv for successfully stripping the' carbons, as they stand Vlooped around the by pullin them backy around the llaten,

der side of the p aten from the typed form independently moi/fable carrier in some cases.

After a form is typed, the outermost carbon may be stripped from the typed form tofthe,y next form, and thereforeino longer binds upon the inner carbone. Said outer carbon strips easily and readily, because there is fno carbon or sheet binding thereon. Then the next outer carbon may be stripped from the .typedform to the succeeding form, and

245 avoid this dificulty, it has been thefpractice', moves easily, because the -outer carbon has to displace the platen, upwardly to permit the composite web to be straightened out, so that the carbon-carrier can strip`the carbons easily back'to their new positions; whereupon the platen has been depressed to typing position. This makes necessary a substantial and expensive reconstruction' vof the typewriter-carriageand the`\ platenconnections, and to provide expensive and bulky appurtenances. An object of thev inuention is to avoid the vdelay and trouble that `ifs usually experienced in round-platen typewriters of displacing the platen upwardly for this purpose, that is, to enable the carbons to be stripped sucf cessfully without displacing the platen, and in' fact while vthe composite web remains looped around the platen, and to effect this result by means of simple, inexpensive devices'which are readily attachable to a standard typewriting machine, thus avoiding .fthe vnecessity of partially rebuilding the in'g device andfthe web-presenting devices i1 can'be attached directly to the typewrltmg experienced of the 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 difliculty.V

one carrier, they Joan 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. f f

, According to the preferred form of practising the present invention',- when the composite web stands looped around the platen .t

at' the Icompletion of the typingof a form, the leadin end of the web may be clamped or fastenecgl to the machine, preparatory to stripping the carbons. Thereupon the feed- If two adjacent carbons are attached to` rolls are cast olf nfrom the platen, thus releasing the web, and the outermost carbon is pulled back around the platen and retracted to position in` register with the next form on the web. It will be understood that since no carbon surrounds .fs'aid outermost carbon, there is nothing to bind upon it, or to hold .it against` the work-plies, and it will slip Q readily back around the platen. '-Then the next carbon (which has in its turn become the outermost one) is stripped back easily,

. since there is no exterior carbon-sheet to bind thereon. The

carbons slip back to a l' point where.` their leading ends are under the .advanced to bring the bottom edge of the just-ty ed form u to a web-severing knife a severing gage beling provided for the lead ing edge of the web.

Each stripper or carbon-carrier is referably in the form ofv a transverse bar aving at its ends bent-u ears; and in these ears there are journalled transverse horizontal rock-shafts, each rock-shaft ,carrying pinions at its ends. The pinions mesh with station- Cary racks, a pair of which extendsl upwardly and rearwardl from the rear end of the usual paper-ta le and carriage of the Underwood standard typewriter. Hence each stripper moves back and forth in parallel- 1sm.

The strippers may be moved by hand, and preferably they are rovidedvwith fingerpieces at alternate si es ofl the machine, so that the 'left hand may move the outerstrip, and then theright hand may move. the next, and the left hand the next, and 'the right/ hand the next, and so on, so that the strip# I ping may be readily effected.

" by individual ,sprin Preferably the'iirst stri per -is connected wit each of theremaining strippers, a l of these springs being tensioned at the operationof retracting the yfirst stripper, and thereafter advancing or tending to advance the remaining strippers,

so that in some cases the strippersy w1l1 become self-retracting, so long as the first stripper is held back against its stop.

Other features and-advantages will hereinafter appear.

In the accompanyingdrawings,

Figure 1 is a diagrammatic sectional side elevation, illustrating the completion of the typing of a form, the leading end of the form havin been advanced to a stripper-v gage. In t is and other views, the polnts of division between each printed form and Figure 2 is' a sectional central elevation short dashes interon a larger scale, showing ttlahe leading end ofthe web as having been c amped, the feedrolls released, and all of the carbon-strippers retracted.P f

Figure 3 is a view similarto Figures 1 and 2, but showing a later stage. At Figure 3 the web is shown as, advanced to the websevering gage, and the next form, with the interleaved carbons, is in position to begin typing thereon.l At this ligure the leading formus shown as being torn off by the knife.

In the Underwood standard typewriting machine, types-l0 strike-against the front side of a platen 11',4 which is journaled by mea-ns of an axle `12 in a platen-frame, which comprises ends 13 joined by a rear papershelfk 14, which inclinesv downwardly and forwardly and curves under and up in front of the platen. This platen-frame is usually shiftab e up and down upon a paper-carriage 15, which is guided upon tracks 16 supported on the framework of the machine 17.

A multiple-,pl

ends of two rack- bars 22, 23, which extend downwardly and forwardly to the papershelf 14. At their lower or-front ends the rack-bars are connected`by a transverse tierod 24; the parts V19, 21, 22, 24 and 25'formingya rigid frame. yIt will be seen that 25 consists of a pair of brackets which are riveted at 26 to the racks, respectively, which are hence rigidly joined by the tie-rod 24. This frame is shown without any table thereweb 18,l either fan-foldedl or consisting of oose plies, is led up from a on, the table being preferably omitted to avoid overweightiv the carriage; but it is obvious that-.a tab e may be supplied,l if

olf the machine, it is only necessary to pull the split spring-studs 27 out of the sockets. These spring-studs tend to open, and hence they bind in the sockets.v Other means fo detachably holding the rack-frame upon typewriter may be provided.

interleaved with the web-plies, which are indicated at 31, Figure 2, are carbon-sheets 32, the leading, ends of which are shown at 32a, Figure 2, at 32", Figure 1', and at 32, Figure 3. The rear ends of the carbons are attached to blades 33 securd`by usual dowel pins (not shown) upon heads 34, Figure 7, and are withdrawn from and replaced upon said heads by means of finger-pieces 35,*in the usual way for the usual purpose of loading the carbons.A The blades in sec? tion have an echelon relation at Figure 2, the outermost carbon being connected to the first or rearmost blade, the next carbon to the next blade, and so on, the innermost carbon being connected to the lowest blade, which is the nearest to the platen, and which is the last to be retracted. k l

The heads 34 are secured alternately upo opposite ends of carrier-bars 36, which extend horizontally from right to left, over= ytwo typed lying the racks 22, 23, and having at their ends bent-down ears/37, 38. ittin over the racks, which serve as guides an supports or as tracks for these carbon-strippers. The ears 37,' ,38 are continued downwardly to form bearings for the ends of rock-shafts 39, which extend across the machine, each shaft havin fixed upon its ends pinions 40, 41, the pinions 40 meshing with the rack 22,

. and the pinions 41 meshingv with the rack 23.

The rack andpinions make a compact, light structure, and are employed to insure that the individual movements of each carbonstripper shall be in parallelism, and that it shall not bind or skew,-even though the stripper is moved by means of its, handle 42 at only one end thereof. l The strippers, in their retracted positions at Figure 2, lie one above anotherupon the racks or tracks, and the carbons extend downwardly and forwardly therefrom, each carbon bein usually about the length of orms, and terminating .at 32a. At the completion of the formy ing operation, the lower end of the rst crm stands a little below the printing line, and at the point marked 43, Figure 1; and the forms.

composite web of work-plies andC earbons stands looped around the platen.- The leadingfendsof the web are set up against a gage 44, which maybe adjusted u and down upon and along a rearwardl -i c 'ned work-shelf 45, having a slot 45a or this purpose, and mounted at the delivery side of the laten 11. This gage is secured Wherev ad]usted by a thuinbscrew 46. Upon the gagel is provided a pair of clips 47, which may be forced down to clamping position by means of a handle 48. This handle is shown in ref leased position at Figure 1, and in clamping` position at Figure 2. It vis xed upon a rock-shaft 49, having a Hat 50, which, when the handle is depressed, permits the springclips 47"*``"to risev rand free the work-web.

`When the typin lof a form is completed, as at Figure 1, t e handle 48 is raised, Figure 2, to cause, the rock-shaft49 to force down the clips 47 upon the front corners of the leading end of the web, thereby holding the same stationar during the carbon-stripping operation. f he next ste is to releasethe feed-rolls 51, which usiia ly run upo the bottom of the platen, to relieve the carbons of pressure.

Then the outermost of the carbons, that is the one most remote from the platen, and located outside'of all other carbons, is pulled rearwardly by grasping `handle 52 of its stripper 36, andthe outer carbon is thereby readily retracted; the pinions 40,41 keeping the moving carbon-carrier inparallelism, or i leading edge of the stripped outer `carbon reaches the retracted position seen at 32",` Figure 2, whichl is just under the bottom of the platen, so that this outer retracted carbon has' no purchase to bind upon or snib' the inner unretracted carbons. Moreover, said carbon-carrier, 36 is arrested by a'stop 54, and1 hence there is no pull' upon the carbon, and' consequently no binding thereof upon the inner carbons, which still remain unretracted. The stop 54 may be adjusted backwardly and forwardly along the rack 22, and secured by a clam ing screw `55, to Yaccom- `modate different engths 'of parbons and Thev next carbon-holder 36 may be thrust backwardly by means of its handle 42, thus stripping the second carbon from the typedl form, as this is nw the outermost carbon, `so yiar as the pla-tenis concernedg the right and hands alternatel thus `Thesesprings .1

The springs will then; pull back the third carbon-car `er, and all three retracted carriers may be eld back by/ iinger` vieee 56. Then the remaining retract the remaining carboncarrier.` However,'the springs may, if desired, be made much weaker, so as to have merely the effect of assisting the pulling back. of the carbonlcarriers; that is, the

rings may be imade to co-operate with the gers ofthe operator in effecting the retraction.` ofl the successive carbons.4 The springs ma be' adjusted to vary" their strength as esired,

When the carbons [are all retracted, their leading` ends all stand at the position 32, just under the platen at Figure 2.- The lead- '44, the gage 60 beingl secur ing web-forn`i,' .whose lowerend is indicatedat 43,is' then advanced'by pulling' theqsame up by "means of its' leadin end after' the clips 447 have been released y pullin down the handle 48'.

The blades may thereupon beattached to the carbon-carrier heads by inserting the usual dowels in the usual sockets. This work-shelf 45 is hinged to a frame which includes 'standards 64a having flanges or feet (65 detachably mounted by screws 66 upon said platen-frame, and also including an indli'ned plate 67, to which the knife 64 is attached, and supporting fianges 67, The folds of the webs may be split by blades 68 on the ends of the carbon-strippers.

Variations may be resorted to within the uur scope of the'invention, and portions of the improvements may be used withoutothers.
