To all lwimmz't may fonce/m:

Be it known that I, VILLIAMJ. Nanne, a citizen of the United States, residing at Madison. in the county of Dane, State et fisco-nain. have invented a certain new and useful Improvement iii VType-Yi'itiiig Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

Certain principles and features of iiiy'in- -veiitioii as described herein a-re included within the generic invention which is described and claimed iii my cti-pending appli- 'catioii tiled A\pril '20,19S,Serial No. 428,212..

The embodiments of my iiiventioirilliistrated iii said application. and herein, contain an operative member, preferably rotary, which is automatically given constant starting position. and which at a predetermined .slieet position is given iii'oveinent eenstant. with that of the sheet from such starting position, preferably through a connection with the platen, and through which various typesl of indicating ,means are called into l operation. The present embodiment is chari the distance to the bottom edge of the sheet.

or to a point a known distance therefrom` during a plurality of line positions, and this automatically. irrespective of the length of the sheet. and beginning considerably iii advance ofthe completion of the sheet.

Others of the special objects-of the illustrated devices or mechanisms are to supply the oijerator with a visual signal becoming effect-ive upon the approaching arrival of the predetermined page-end, and with a practicable and dependable signal, preferably audible, npo'n the completion of a line a.predetermined distance' from the end of the'sheet,

Still other. objects ofthe present branch or division of the invention are indicated hereinafter. division. are not restricted necessarily inall cases to employment-in the precise Oonibina- The features of this branch or tions and relationships herein' shown and described, and some of them are adapted to be used for 4other sheet-position indicating purposes.

An important consideration upon which invention, are based, is that of so contriving and arranging the controlling means and the ine-.ins for causing the Operative member to turn in unison with the platen, that they shall be practically instantaneous in action,

so that the Operative member actually shall be given movement simultaneous with thatof. the platen, from its vconstant starting position, when the sheet attains 'a constant predetermined position, 'without being inliueiiced by whether the sheet arrives at such position during a feed-movement but before the coiiipleticn of such movement, or atthe completion of the feed-movement.

The importance of .the consideration-just referred to can be explained as follows: Let it besiipposed that an indicating mechanism be` applied to a typewriting machine,

the said mechanism having a sheet-controlled controlling member ytheoretically .65 the preferableembodiments ofthe general'A `'iven movement with the-,platen when the i end ofthe sheet. attains a lr(, listaiice 'of exactly 20 single liiie-spaces-froni the print-- ing point; and `for-the sake of clearer exposition let it be supposed that the spacing is b v triple-line advances, and that at the end ot' the advancing movement immediately preceding .the calling into action ot' the said controlling member the end of the sheet is 901iliiiesdistant from the print-ing point. lt is plain that unleslq the' controllingl member is entered into liioveineiit with'the pla-ten during the next advancing.-inovement. that is to Asav` when the sheet-end passes the QU-liiiepoiiit.A orbe'l'ore itiagain comes to rest, the iiiiiiber will viiotrbegin to move with the platen until the beginning of, thenext advancing."niovbnieiit, iiaiiielv, thi-ec lines beyond the 2G1- line point, 011171, lines from the sheet-end.fw In otherwvords; unless the said member enters finto such movement. with the platen during such ad'-y vancing movement, itcfan'not begin move;y ment when theend ,ofthe .sheet-attains a dist-ance or' exactly 20 lines from the printing point. The uncertainty possible Will be seen if We further suppose ano-ther sheet to have been shifted so that the end thereof attains a point one-half line nearer the printing point than before, at the end of a triple-line advance. .In that case the sheetend wouldstop after said advance at a point 19?; lines distant from the printing point, instead of 2% lines:,that is to say, theoretically the member would have been moved with the platen to the extent of on`efourth of a line-space at the'end of the a'dvance movement. But if it were notso moved, its subsequent advance with the platen willbegin when the sheet-end is 192 single line-spaces distant from the printing' point, and not 1731L as before. Such vari- '.ati'ons from accuracy are not-.desirable in practice. If such a member is to controlindicating means such as, indices, or a locking means, or any kind of signaling agency, it is highly desirable that'it should be under the control of operating means that will actually coordinate its'position with that ot' the sheet-end`under the circumstances of service, and not call it into action from its constant starting position in one case when the sheet-end is 19% lsingle line-spaces dis tant .from the printing point, and in another when it is 171 linespaces distant.

My general invention therefore provides actuating, controlling and intermediate means, all of which are practically instantaneous in action, so that the controlling member actually is given movement With the platen from its constantstarting'position -when the sheetend attains a constant distance from the printing point, Whether the sheet-end arrives'atI such constant distance in the midst of an advance movement,` or at thc end ofone. My present branch or division of the general invention comprises .novelties in constructimi directed toward the attainment of delicacy and power in all of the said means. i In the accompanying drawings, Figure 1 1s an end view, partly broken away, of a typeivriting machine showing the embodiment aforesaid of my present invention applied thereto, many of the usual parts of the machine being omitted; Fig. 2 is a top or plan view of portions of the same, but relatively enlarged, and with the index-carrier 6 partly turned in order to show the indices thereon more clearly; Fig. 3 is a vieu' of parts of my mechanism in crossseetion on the line A.f\, Fig. 1; Fig. 4 is an end View of the index-carrier 6 showing the interior clutclmnechanism thereof. part of the incasing structure having been removed; and Figs. 5 and 6 are vievvs of other details of the mechanism, partly in section on the line B-B, F ig.2.

structure represented in lny drawings, the usual key-levcrs 38 having the Yfulcrum 44; are actuated by the keys 59, and in turn actuate the type-bars 78, pivoted at- 80, so that the types 73 are carried to the printing point. riage frame is indicated, but with portions omitted and partly broken away. A portion of the usual platen frame 40 Fig. 2) is shown, together with the platen arbor 1,3, platen 10, platen head 39 with sleeve 39 (Fig. 3), and paper-table 8. These Jarts are all Well-knownin the art and nee not be more fully described.

Referring first to my actuating means for the index-carrier 6,I use as a part thereof a friction-clutch mechanism embracing frictionally-engaging members, one of which is radially exterior of the other and either of which may be the driver. A highly ef fective form of clutch is described as follows: The core-Wheel 56 is mounted upon the sleeve 39a of the platen-head 39, so that an axially-extending seat or recess 5 (Fig.

4) fits over the usual set-screw 30in the hub of the platen-head as over a key and insures unison rotation of the core-Wheel With the platen. The Washer 11 may be used if desired to space Athe parts slightly away from the end of the platen, but it forms no part of my invention. I use as a matter of convenience the Sleeve 71 to maintain the core- Upon the said core-Wheel. is placed the shell ordrum 6, previously referred to from one of its functions as the index-carrier. For convenience in assembling I prefer to construct the said drum 6 with a rear wall yheavy enough to support the pin 53. Upon pin 53 is journaled the lever 32. This lever is supplied at one end with the projection 14, at'the other with the tail portion 54, and adjacent to its axis with the pins 60, and it isy centrally channeled in the plane of its movement to admit of the free passage to the said pins of the ends of the frictionband 57. This band is adapted to conform to the periphery of the core-wheel 56 and is fastened at either end to one of the pins 60, conveniently by means of a riveted loop, the arrangement being such that when the lever 32 is moved in one direction the said band is tightened about the said core-Wheel grippingly, and when the lever 3'2 is moved in the other direction the band is rendered more slack and the friction between it and the core-wheel is eased. The spring 55, fastened at one end in ther-.left of thesplit post 5i) on the inner wall of the drum 6 and held to its work hy the post 58 also on the said wall. 'presses against the tail of the said lever 32 in such a way that. the lever tends to move in the direct-ion to tighten the band 57 about the said core-wheel 56.

The upf standing portion of plate 8 bears the lat- .is journaled the sleeve 21 having ixedly plate of the drum, which isreniovalile for convenience in assembling, isv supplied .with a slot T7 (Fig. 1) through Which the projectionll may freely play when the said lever is oscillated, and with a series of threaded holes 67, preferablyy placed at linespace intervals, into any one of which thel counter-sunk screws 99 entering tapped holes 991 in the rear Wall hold the said face-plate in position. j j

Upon the paper-table 8 of the machine 40 is attached the superposedplate 81 b vmeans 4of the large-headed screw 17, the said screw tting a threaded hole already in the machine. As this threaded hole, may vary slightly in position, I allow for adjustment by providing a hole in' the plate,l 81 that is larger than the screw-shank, thel'large head of screiv 1T covering such a hole Whatever the adjustment. A counter-sink 5 for the screiv head is provided to `facilitate the erally extending shaft or` pin 20, upon which attached 4thereto the lever-weight 66 and` thev paper-feeler butt 281, the latter being recessed or niortised at its end to receive upon the pin 23. The bevel 24 on the feeler-butt coperates with the tail-lug on the feeler to limit the relative movements of the two parts to a one-Way flexion. The end of the feeler may be slightly rounded for the sakevof a smoother action against the sheet. The lever-weight 66 is preferably given the form of a disk with its center of gravity eccentric toits axis; and it has a tivo-fold function, first, to return the parts connected therewith into operative ptisition, and second, to a'ct as a lever upon the paperefeeler 28 through the sleeve 21 and the feeler-butt 28]L when the pin 151 is acted upon by the stop 15. The platey 81 is Supplied with a slot 4 4into which the feeler 28 has its path, and With' the laterally extending safety stop 42 to prevent certain sliding parts (not shown) on rod 62 from being thrust against the stop l5. A down ivaidly extending portion of the said plate 81 is given the bevel 9 to serve as a guide for the backing-up bottom edge of the sheet,l the side edges of said portion serving also as a safety provision vto prevent the before named sliding parts lfrom being thrust j against the paper-feeler'28. The saidA parts are in the nature of paper-guides and are my invention and are not shown.

The weight 66 bears the pin l5l upon@ which is' journaled the bushing 16 havingj tixedly attached tliereto'the'sliding stop 15,

against the sheet.A as shown in Fig.

a. countersink provision permitting the said bushing to lie pai'tly,\vitlim the contour ot the said weight. I use tliebusliing in order pressure otprojection "14; and either o these modesl et' operation may be enipha# sized over the other by altering the forni` and proportion of the said stop. Provision made for backing-up the projection 14 past*- the said'stopv by suitably sloping the throat portion 87' thereof so that the proin such a movement. The statt' portion 88 v l `jection will liftthe stop idly Vfrom the rod'` is given a. slopingcontour in order that f when brought back against rod 62gby the A Weight 66 the stop will tend tov assume the position slioiin in Fig. 1, and not lie awaylfrom rod 62 in a partly elevated inoper ative position. The said statt portion ofthe stop serves also as a' positioning checkupon the return .movement of the. stop toward the platen after its release by projection 14;; Provision is made against 'an excessive movementI of weight 66 upward'V past its center of gravity, the reduced portion 90` of the stop coperating `Witlisleeve 214 to check any such iii'ovenieiit.A `Provision is made against the accidental soniersaulting of the stop, as for instance ithen 'projection l-l is sharply backed-up past it, or when the machine is carriedl in an inverted `"position" from one place to another, by the addition" ot' the safety uiideihang 89 to coperate with the safety projection 42,

The action of the niechanisin thus lfar de`r scribed is as. follows: The paper-sheetl 45 Iis entered into the machine in ordinary inaniier along the paper-tablev 8; the iveiglit 66"` holding the paper-teeler i28 in its iiornialV retracted position .so as to permit the linob'-` i sti-acted entrance oiLl the sheet` and also holdingr the stop 15 in itsiioriiial position in the path et' the projection 14.' Theslieet is t'lieii advanced in the usual way' through` the iiistrunientality of the platen. `.\s the platen; is rotated. the druiii` f3 'also' rotates. under the action of the y v, clutch-nieehanisiii 'contained therein, and vsooneiiir laterlirii'igs the projection 14 against 'the stop 15. Fur'- thei revolution ot' the platen .will push the 4 ,.stop toward the pi'iper-table, rock the weight I (36. and through it vbring the paper-feeler 28 the sheet were not presentl the'feeler wouldy -stop will cause the lever 32 to be rocked upon its axis 53 against the action o1' the 4spring until the friction-band 57 is only radial closure.

slackened about the driving core-wheel 56, thus reducing the friction and therefore the force exerted upon the stop and connected paper-feeler. That is to say, the drum 6 is clutched with considerable tirmness to revolve normally with the platen, and yet a touch upon the controlling projection 14 will stop it instantly and surely and smoothly in a position of rest. The clutching action of the friction-band may be further described as involving radial closure, as distinguished from` axial closure, the frictional pressure being directed along radial lines rather than along lateral or.axial lines.` I do not regard it as essential that the pressure should be applied to a surrounding contormable part and directed inwardly upon the driving part, as disclosed in the present embodiment of my invention, nor that the clutching action should involve Various well-known types of'friction-clutch could be used in'- stead of the one shown.

The mechanism will remain in the position shown in Fig. 5 during the presence oi the sheet over slot 4 in the path ol the paper-feeler Q8. Eventually however the end ot' the sheet will pass from under vthe said t'eeler, stop 15 will no longer act detainingly upon projection ll, lever will be permitted to rock cn its axis under the actuation of spring the conformable band 57 will be tightened grippingly about the core-wheel 5G, and the drum (3, now frictionally clutched to move with the platen and no longer detained, will advance cordinately with the sheetY through the position shown in Fig.v 6 and will move thereafter cordinately with the sheet until the sheet leaves the machine. As the said drum always begins its movement after release r'from the same angular. position, it will alays stop in agiven angular position after a given angular movement from starting position, and as moreover it always begins its said movement when the end ot' the sheet. is a constant distance from the printing point, since the point where the feeler-end lneets the sheet is necessarily ixedly distant from the printing point, and as the sheet is advanced cordinately with the said drum during the said movement of the drum, the end of the sheet will always be a constant distance from the printing point at the end of the said given angular. movement of the drum. I place the stationary index 34, shown as clamped between the shield l-3 and the platen frame 40 by the screw 1S, adjacent to the said drum, and I .supply the indicating portion ot the said drum which is presented opposite the said stationary index in the constant starting position of the drum with an index 89a that will indicate that position of the drum; I further supply the said drum on that portion thereof which is presented opposite the stationary index after an advance of the sheet and drum cordinately with each other, with an index thatwill indicate the new position of the sheet; and so on around the drum for every successive position ot' the sheet, at will. That is to say, if after the irst movement of the released drum or index-carrier the end of the sheet is distant nineteen single lines from the printing point, I supply the indicating portion of t-he drum then in indicating position with the` index 19, and in order to indicate when the end of the sheet is distant eighteen single lines, I supply the drum with the index 18, and so on down to the end of the sheet. In myrdrawings I show the indication by single-line' progresses, the indices 6a here being numerals in descending order. Other indication than by single line indication may be employed,

and other units than the line unit. It is of course immaterial whether the stationary and vmovable indices come to relative rest exactly opposite one another, or whether the distance is given to the. end ot" the sheet or to a point a fixed distance therefrom, orl whether the indices in themselves signify distance-units at all. I prefer to use simple numerals indicating i the decreasing distances to the end of the sheet and involving no mental calculation nor memorizing on the part of the operator. I also supply the drum or index-carrier 6 with a second series of indices 6b, preferably distinguishable in appearance from the series Gf* hereinbefore described. The purpose of these indices is to indicate to the operator thi7 extent of a given backing-up movemer'.

Their action is described as follows.: Suppose the drum 6 to stand in its detained position of rest as illustrated in Fig. 5, wh'ich is the position it will have during mostl `of the progress of the sheet, the index 89" thereon lying opposite the stationary index 34: if the platen were now to be turned backwardly the extent of oneline-space', the drum 6 would move away from stop-detained position to the same extent, bringing a new indicating portion before the stationary index 34. I can supply this portion of the drum with the index 1;'and I can supply it with the index 2 to indicate a backs@ ing-up movement of two line-spaces in ex# tent; and so on around the drum, at will.

The indicating surface upon the drum 6 is further availed of to give the operator sign that the end of the sheet is near. I use for a stationary index 34 a shield-pointer that conceals one portion of the drum from the operator, and I divide the indicating surface upon the drum into two differently appearing segments, one of which is visible to the operator during the detained position of the drum, and the other of which is not visible but lies behind the shieldpointer in that posit-ion of the drum. In my dran-'ings I show the first-named of these segments as bearing the indices S9` and 6b, which may appear in red, and by preference I supply this segment with a ground of black, and the secondof these segments which I cause to bear the indices 6a I prefer to supply .with a ground of White, although these are not the only distinguishing means possible. lYhen the sheet-end releases the drum and the White segment comes into view, the change from black to White attracts the operators attention and he knoivs Vthat the end of the sheet is Within a given distance of his printing point. It is of course not essential that the white segment should come into view at the very first feed-movement of the platen after the release cf the ,carrier to move therewiththe black segment may be extended under the shield-pointer to any required extent so that several feed-movements will inter-` vene before the White segment comes into vieiv, and consequently this signal may be given when the sheet-end attains any required distance from the printing point. It is not essential that either portion of the drum be supplied with indices in addition to such a signaling means, nor that such signaling means be provided in addition to either or both series of indices.

It is to be noted that the structure hereinbefore described. is especially adapted to be added to existing machines. there the device is built into the machine many of the functions performed by the said added structure can be more conveniently peri formed by the structure of the machine proper, as will be understood.

I provide the following indicating means for giving a signal, preferably an audible signal, when the end of the sheet attains a predetermined distance from the :printing point, and for rendering the machine inoperative, lpreferably through means `preventing the actuation of the printing mechanism, at a predetermined page-end position.

The carriage p extending pin 74, upon which isfjournaled the bell-lever k1- soas .toL move in',a`p`lane outside the path ofthe projection V14. lThe said 'bell-lever connected with the pin 63 by means of the rod64.

on the lever 69 frame 12 bears the laterally bears the pin 61, 'ivlfiichI is" The lever 69 is journaled upon the laterally extending pin 37 on the end of the carriage frame 12, and a similar lever and pin Will be understood as lying behind the one shown, mounted on a similar carriage-frame structure at the opposite end of the platen, the tivo levers 69 being integrally connected Vby the bail-rod 3. Against this bail-rod at a point between i the ends 41 of the mainframe of the machine rests the lever 70 ixedly mounted on the shaft 2, which is journaled at either end in the said main frame 41 so as to rock thereon. Fixedly attached upon the shaft 2 is the lever 25 bearing the pin 33, which is connected With the pin 46 on the lever 51 by means of the rod 36, the said lever 51 being tixedly attached to the shaft 48Which is journaled at each end in the main frame 41;. This shaft 48 carries fixedly attached thereto near either end the two levers 52, one thereof being shown and the other being understood to lie immediately connected by the laterally to form in effect a rocking bail-piece, and it carries also the radially extending spring or wire 72 on which is attached the a position nearer or farther from this bellhammer, so as to be struck as desired when the shaft 4S isrocked, is the bell 27, mounted on the frame-extension 86 on the main frame 41. The usual key-levers 38 ranged one behind the` other laterally across them'achine are each supplied with the overhang 381, the parts being so stationed that when the bail-piece Ois rocked it will lie under the said overhang and prevent the actuation of the printing mechanism. A spring 47 attached at one end to the rod 36 and at,l the other to the pin 49 on the main frame 41 tends to hold the said parts in unlocked operative position against the stop S1 on frame 41. This portion of the mechanisni operates as follows: The pin 68 having been placed in the desired screw-seat 67 and the sheet having been advanced until the said pin has been brought around by the released drum 6 into contact with the lever 1, or adjacent thereto, such position being the position for Writing the predetermined last line upon that sheet, and moreover the said last line having been written, the usual abrupt spacing forward of the platen in advancing the sheet will cause pin 68, through lever 1, rod 64 and lever 69, to rock the bail-rod 3 downwardly against lever '70, thereby 'turning 'shaft' 2v and, through lever 25, rod 36 and lever 51, rocking shaft 48 and causing the bell-hammer behind the same, extending bar 50 so as bell-hammer 26. In Y 26 to descend sharply toward the bell 27 125 'move his sheet, and he can d o so Without waste f time ir''trial of the printing mechanism to sce whether` it is inoperative. The

action of the above parts brings alsoV the bail-bar under the overhang 381 on the key-levers 38, thereby locking the printing mechanism against use, so that if the op erator fails to notice the bell signal he will have further indication that the sheet should 'bc removed. In case he desires to con- .tmue printing upon the sheet he has only ing-up movement of the pin 68 against theA lever 1 the bail 3 lifts idly away from the lever 70, the bail 3 serving later as a weight to restore the lever 1 to operative position.'

'My invention is provided with means for holding it in disuse, as follows: The upstanding wall of the superposed part 81 bears thereon the pin 79, upon which is jour.- naled the latch-lever 76 having a projection 31 adapted to enter the recess 75 in the weight 66 `so as to lock the said weight against movement on its axis. The said latch-lever is preferably constructed of a resilient material, and it is supplied with the underhanging stud 74 adapted to enter the recess 35 in the' said part 81 so as to hold the said latch-lever safely out of engagement with the said Weight. If the operator desires to ,place the mechanism into temporary disuse he has only to shift thev latchlever from its position as shown in Fig. 2 untilv the projection 31 engages with the recess 75 in the weight, the stud 74 in this case resting against the edge of the part 81 and holding the latch-lever in locking position. The carrier will now be held in d etained position until the parts are released, and the indicating mechanism, with the exception of the indicesf", will be rendered inoperative.

It is to be noted that the structure hereinbefore described provides for backward movement of the Asheet at any time: If the platen is turned backwardly while the feeler is in contact with the sheet, as shown in Fig. 5, the'resulting backward movement of the drum 6 will cause the projection 14 to move backwardly, relieving the stop 15. of pressure, whereupon the weight 66 will be enabled to retract the feeler from contact with the sheet, and the sheet however thin and irregular of surface can then be backedup with as great freedom asl though my devlce were not in use on the machine. And if the sheet be advanced to a point just beyond its release of the feeler. as shown in Fig. 6, and then fed backwardly, the bottom edge thereof will carry the feeler backwartllv ahead of it, the axis 23, bevel 24 and tail permitting the movement, and atl the same time the weight 66 will move the Locaties l feeler-butt 281 toward the platen until the feeler 28 clears the sheet.

A mechanism such as I have described satisfies the objects of my invention in what I regard as the most perfect manner, but I do not confine myself to the exact forms or arrangement shown in all cases. It is to be noted also that although I show the paperfeeler 28 as intersecting the path of the paper-sheet at the paper-table, I do not limit myself to this construction.
