To all 'whom it may concern:

Be it known that I, HEINRICH D iiEwELL, subject of the German Emperor, residing at Charlottenburg, Germany7 have invented.

i 970,694, dated September th, 1910` I have described a device by means of which, when Setting typo by means of register bands any errors can 'be made inoperative. when making the band, definite groupsot holes in the band, which represent lines, words or individual characters, being made inoperative. In this arrangement the type space indicating device must be correctly setin eat-li rase, which operation is effected by the paper carriage. ofthe typewriter connected with the band perforatingdevice being moved backward. As the feed of the paper carriage corresponds exactly .with the width 'of the printed letter to be set, every optional group of characters can be made inoperative` the position of the paper carriage or the written line indicating' the correct length to be adjusted. The composer, however, who is making the band must pay considerable attention to the adjustment of the paper carriage j, in the event of its not returning into the position for beginning a line.

A rough ad- .justment of the carriage maylead to'incorrect length of line. Aceording'to my present invention the paper carriage is adjusted correctly automatically both when doing away 'with a defective line. and also when removing incorrectly written words which occurs most frequently. In this' lnaniiernnexact adjustments are avoided.

1 According to pending application the perforated word separating symbol,v which causes the spaceA member to be set, forms the one limit ot a groupof holes ivhieli'represents an incorreetly written ivord which is to be made inoperative. Now according to my present. invention, when perforating this symbol a stop or'iilautn'ient is adjusted which limits the backward movement of the lpaper. carriage the' eventl of. the word last. written being removed. The stop is adjustcdat each pressureon the Word separating key before the '.ie above mentioned cti-' paper carriage is fed forward by depressing the Wordseparating key. For this purpose the stop iscaused to .follow the movement of the pa )er carriage or of 'an intermediate member connected therewith the amount of the total Width of the word last written u`n` til it contacts withasecond stop arranged on the paper carriage or on an intermediate member. The first stopv is fixed again until the next time the Word se arating key is used. At the end of the line the stop together with the paper carriage is'rcturned into the position for beginning a line.

The keys by means of which incorrectly made groups of holes are made inoperative are designated hereinafter as Wordcancel ing key and line-canceling key. In addition the line-separating key and the word separating key come into consideration. lAll the other keys are designated briely as type' 4inveiition is not limitedj," however, to this form. On the contrary," type snace indicators of every kind can be provi ed 'with the means according to this invention and be thereby arranged forcorrecting parts of matter. Also, the mechanical devices can be varied in manifold ways without departing from the spirit and sco e of my invention.

` l' te erring to the drawings, in the body or frame 1 of the typewriter'the type levers90 5 and 91 are mounted in suitable manner and connected by draw rods 92 with. levers 93. These are arranged on shafts 94, which, on the one hand, carry at one end levers 95 and are so connected by these with thekp'ys 96 that., when a key -is depressed, one of th shafts 91is rotated, and the levers 93 act by means of the draw rods 92 on the type levers 90 so that' the type 97 corresponding -to the key which has been depressed strikes against the platen roll, whereby an impression of the type is obtained by means of the ribbon 98 located between the type and the -platen roll. On the other hand, the shafts 94 are carried at their other end in the frame of the perforating apparatus and are journa led therein at 100 and 101. They traverse a number of plates 102g, 102b and 102, 102, as well as eleven plates 103. The plates-102@l to 102d influence the feeding mechanism of the paper carriage, while the plates 103 effeetthe selection of the punches. Then any key is depressed the corresponding shaft 911 is'rotated and plates103 or 102` to 102r1 are displaced. This displacement is brought about as t'ollows -In each of the plates 102l to 102dj and 103 is provided for each shaft a recess 101 and Within this vrecess two teeth or shoulders 105 and 106 Fig.I 5. riphery of each shaft 91 are ribs or projec tions 107 and 4108 arranged diam frically opposite one anothe But the projections 107 and 108are so t isplaced longitudinally of the shaft relatively to one. another that a gap on .the 'one side always corresponds to a ribou the other side. The shafts 94C are divided into' two groups as seen in vsection in Fig'. Those located to the left in Fig. 5 are rotated clockwise whenva key is del pressed whereas those on the right are rotated counterfcloekwise when a `key islde-A pressed. But''the plates 1.02a to 102d and 103 are always-`dis`placed-in th'ef'same direc-A tion, namely vin thatI shown byit'the. arrow` 5U the recesses of thelpla'tsfaird the projection'sfv 1 07 and thefshaftstll are positionedf* @responda opposite 'ie- 1nove's; 'tlie plate, in'whi'ch" thgsllo i located, from the" right to the left, rotation th'eprojee aangaat iatlserp-lageswhah are. not t@ :be placed in front of the 'shonl dt prevent the 'plates' in question 107fand 108 need. never On the pel L 'When ashaft on thedeftlV Iis'4 obvious from "this thatV gess, :but: that, on lieti-"103.8090158 108: may be at'anytime infthe'lrecessof 'each plate., On the right-hand side the correspondng .projection and shoulder a re located reversely, z'. e. the projection 108 is aboye and the projection 107 ,and shoulder,105.are

Each of the plates 103 has an extensionl 110 running out into a hook 111. The latter engages in a hook 112 of an angledever ing to a key beingstruck, the angle lever 113 rocks under the action ofthe sp1-in 1 116 about the roundhead 117 of the punc 114 and the extension or shoulder 115 arrives in front of the 4strikin bar 118. Whenever a key .is struck two of t e plates 103 are moved, and leach of these plates corresponds toa special punch which is rendered operative in the described manner bygthe displacement of the plates owing to the extensin 115 corresponding to the punch in question arriving in front ofthe striking bar 118, and when the key moves further a special coupling', is

released whereby the mainf'shaft 7 8 of the:

perforating'apparatus is operated. 4At'this shaft is a ca'm 121 which, when the main shaft' rotates, impels the ybar 118 forward. lby means of the roller 122. This forward movement takes place during the third. quarter cfa revolution of the main shaft and'has' terminated at thev commencement of the fourth' quarter. At this moment the v'rith-- drawal of the bar 118 begins bv means ofthe'v` angle lever 123 and the roller .124, on which thebam 121 gacts, when'the forward move;4 ment of the'striki'ng bar isterminated..I

(loir sequentflythe spring 116 pulls the 'angle lever 11,3 around Aso far that the' hook 112 lies against the hook 111, whereby further rotation of the anglev lever 113 temporarily prevented. In order that the point ofthe lever 113 can slide unlnpededly over the bar 120 when the punches are driven forward, at the moment when the.. punchesl are driven forward the bar 120 is moved downwardly -by the projection 121 of the cam 12,1" so thatv it does not contact wit .the point of the levers 113` `The plates -102a to 102d have extensions 130 and 131 which coactl with the vertical I'arms 132 'and '133. of angle levers. The

horizontal arms' 134, 135 of these angle levers form catches or pawls, by which the angle levers lare held in their normal position. v.The angle levers 136 aire pivoted to rods 138 in like manner as the angle levers 113 and possess a horizontal arm -137 which can be placed in 'the path of the striking bari-28'. This, is brought about by the spring 137 lasso'on as the arms 136 are. unlocked by -tlieangle levers 135,. 134.- Four 'rols138 (Figia) .are provided corresponding the four plates 102a t'o 1021.

,Pawls 139` are provided o n the rods 138 and engage in the ratchet Wheels 16, `17 18, 19 When one rod 138 is moved forward t-he Icorresponding pawl-139 rotates the appertaining Twheel 16 5o 517,18, 19. `-Thcsewheels are prevented fro-1n ',l'noving backward by suitable pawls 140 ',underthe intiuenceof springs 141' (Fig. 7). The number of teeth .of the ratchet wheels4 1G, 1 7, 18, 19 is various and, correspond- 'ingly,vth e feed ot' the Vpaper carriage which they occasion is various. The motions of "the'individual' wheels 16 to 18 is added by means of differential gear and imparted-to l.the paper carriage. The mode ot operation of the differential gear has .been described in detail in my United States Letters Patent #953988', dated April 5th, 191.0.

Referring now to Fig. 1, the framc2 of the paper carriage runs with rollers 3 on rails 4' secured on the body' 1 of the t [Je-' writer. The platen roll' is mofnnte in New ifA the lattertogether with .the f1-'aine 1 25 ispushed forward when the main shaft 120 r 40.

The devices for securing the paper on the platen roll, for raising theplaten roll and for rotating the saine are not. shown because they maybe constructed in optional manner. and are sutlieiently4 well-known. operation is not relevant` to the present in' Their mode of vention. On the fran'1e2 of the paper carriageis secured a rack 10 with which a pinion 11 meshes. The latter is on an axle 12 which, on the one hand, is journaled at 12* in the'. typewriter and, on the other hand, at 1`2fl and '1,2c in the frame of the perforating apparatus-land carries the vgear wheel 13. (Fig. 2'.) I n contradistinction to the ordinary arrangement a' spring'tends to :bring the paper carriageconstantly into the .position which the carriage occupies when b e- 'ginning a line.'l When Writing, the pa per carriage is fed by feeding mechanism which worksA against thezspringJ and is driven by the mechanical force serving for perforating 'the paper band. Y This arrangement makes it possible for the pa er carriage tojnove backward automatical have b een'struck,` namely after the depression'v ofthe end-of-line key,:the line-canceling key or the word-canceling key. The

vgear Wheel 13 'meshes with a'gear Wheel 1 4 which. runs loosel on the axle 15. This `axle carries secure on it another gear Wheel 2 2-which meShesZWith the wheel l-21 secured on `the faxle 20 of theieeding mechanism'.

This Afeeding mechanism' comprises 'four wheels 1 6, 17, 18 and 19 which can be rotated independently one of another (Fig. 3).

," after ldefinite keys These Wheels are?v moved by pawls which are l coupled in. siiitablc manner, means 'of universal barsrnoved 'by the keys, with the source offpowefggoperating the punching device.` The lnotonimparted to the rWheels is added inl known manner byditl'erential gearing-"anfd imparted to the axle 20, by which the axle '15 is driven 'with tlie intermediary of the gear wheels 21 and 22..` This axle imparts its rotatory otiontojthe wheel 14 by means of a detacha le clutch comprisingitwo crown Wheels 37 a'nd 38. The crown wheel 'vcomprises a-,l'o-w'erful disk 25 (Figs. S`

and- 9) p rovid'd atits edge with axial4 grooves 26 In these grooves rods 27 move axially, sald rods being shaped like a' ratchet. tooth at one end and -at the other carry a round extension 4254 around 'which a spring 2f) is arranged.- Each rod 27 has a flange-like. enlargement 30 which limits''i'ts" displacement. The disk 25.is firmly connected with 'the axle 15. i

Betweenl the disk 25L and the flanges 30 'isa disk ltagainst whichthe flanges'abut and which serves forholding 'back 'all'v the rods 27 against the action et the springs 29. l To l'this end,- the disk 31 'is integral with a 'bushing 32 havingfaange 33.A .By means. of j a lever 34,whfo'se 'forked end claspsthe bushing2,ffthelatter-can be moved axially. A casing is pushed over the rods 27., and the disk 25 prevents the rods 27 'falling out of the"grooves 26 and supports the springs .29 by means of its end 36. The extensions '28 are guided in holes in the end 36. The disk 25 with the projcJting, ends of the rods 27 formed as teeth forms a.

crown wheel with movable teeth which can be pressed back individually and independently one of another. This crown wheel will be hereinafter briefly designated crown wheel 37. Opposite the teeth of the rods 27 is a crown wheel 38 provided with oppositelydirccted, fixed teeth and secured to or integral with the gear wheel. 14.

The latter is free to rotate on, the axle 15.

'site'the crown wheel-42 is a crownwheel 45 Vprovided with `-movable teeth 44; These teeth are moved toward the crown wheel 42 -3'0 by springsand tend to engage in the ratchetl teeth of the latterwheel.- On the wheel 45 is -also'an axially displaceable bushing-46 having lianges 47 and 48. By means of these fianges andwit-h the intermediary of the ley vers 49 and 50, which engage like forks around the bushing 46, the teeth 44 ofthe l,wheel 4 5 can be ,displaced and removed from the crown Awljxeel`42. The crown wheel 45 is free to rotate, but is axially non-displace# h able on the axle 15 and is 'prevented fromro- -tating by a noseor projection.51"located between a lfixed stop 52 and an elastic stop 5,3.

. (Figs. V2 and 7.) The stop 53 is aile'ver revo- Vluble around a pivot 54 land under the action of a'pow'erful spring 55. By `means of the lever 53 this spring presses the nose 51' againstt-he v stop 52 and thereby'elas tically secures .the crown wheel 45 in its position. This arrangement forms a'- buffer i elastic so that great Awear and'tear of the device,.by which the limit stop for' the backward motion of; the paper carriage is made gearwheels and other'parts is avoided. The

' crown wheels 37, 38,42 and 45 form two .dc-

tachable clutches, of,V which one comprises the crown wheels 37' and 3.8 andthe otherthe' crown wheels 42and'45. The former clutch is disconnected whenever the paper carriage returns, and the latter' when thepaper 'carriage'jreturns into `the position atfthe beginningfof the line, and, in addition, 4when perforating the iWord separating symbol.

4As the paper carriage is fed yvarious distances "wllich are graduated according to Ysmall units, provision must be made in the 4clutches that the papercarriage is held fast,

independently'of the position ofthe axle 15,

exactly at thatpoint up to which it is to movebackward and 4coup ed with the ratchet mechanism. To this end, eithe' the c rown wheels of the clutches must have very fine teeth or, as in the present instance, special arrangements must be made which. assure lthe paper carriage bein finally adjusted.

VIn thelv illustrative embodiment this is effected by means of the movable te'eth of the crown wheels 137 and 45 as follows: TheA crown wheels 38 and 42 each have 56 teeth.

Opposite each of these teeth are the movable ratchet teeth of the crown wheels 37 and 45. The number of teeth of two opposite-crown Wheels thus .form relative prime numbers. Consequently, of the'l teeth of the crown wheel 37 only one tooth can enter eachftime entirely into an opposite tooth gap of the wheel 38, While the remainin teeth do not or only partially en'gage in t e teeth gaps of the wheel 38. The number ofthe various reciprocal positions which the two wheels 43*( and 38 can occuply relativelv to (e ane en-` other, each .of whic *is assured by gagement of one movable tooth in a tooth gap of the opposite crown wheel, is equal to the product of the two numbers of teeth,

'thus in the case in question 840, 'so that :the

dilerencet in the position of the pa er 'carriage amounts toonly 1/840th part o a rev0' lution. The same tine adjustment is obtained in the case-'of the'crown wheels 42 and 4.5, mamans @which the stop 401s adj usted. 'Itfisito be noted'here that the post,

tion of the,stbp 40 must be 'assured in two directions, ,ti-n1 the one'h'and against the action of the spring 43 tending to' move the. stop in the direction of the normal rotationA of the wheel 14, andl on the-I other-hand :against a rearwardmotion by the paper car- `ri age, Aor bythe stop 39, when -thejpaper carriageV is to be placedbackwardj-*to this stop. Now'the ratchet teeth of thel` wheels 142 and40, are so arr'an ed 'that the motion of .the stop 4 0, which mlght beA brought rabout y bfy the rearwardly-moving paperfcarriage,

must vtake place opposite to the :direction-of 'the ratchet teeth,so that a toogreat rear-f -ward "movement `is rendered impossible. The reverse motion, however, is not" ossible without disconnecting the clutch etween fthe wheels 42ar'1d 45, because inathis event .the-sprin 43`Would have toinove backa number o teeth ofthe wheel 45.` "This-can be readilyl prevented by making the springs which keep these teeth in engagement with the wheel 42 suliiciently 'powerful .toi-'otter sufficient resistance to the action of fthe spring 43. The clutchesjormed* byjthe crown wheels' are disconnected-in each case, as'requu-ed, by means of the levers 34, 49 and 50. 'Lever 49, whichkcoactswith` the iange 47 is revoluble around the pivot `5i' and carries at its end-a roller-58 lyu g on the r. is generally stationary and is only driven'l seem lkey-shaft 68 which carries at its end-thekey 68 which is for eliminating an incorrect word, z'. e. the word-cancelingfkeyfy The cam 59 is secured on an axle 70 which carries in addition the cam 71. Against the latter therel rests the roller 72 providedy at the end ot' one arm of the lever-34 which is revolublc around the fixed-pivot 73. The shaft when the paper carriage is to be moved backward,z'. e. when the end-ofline key, the linecanceling key and the word-canceling key are struck. In thisevent the shaft 70 is coupled with-the source ofpower operating the perforatingr4 apparatus, whereupon it rotates once and then automatically stops. The coupling devices are not more particularly described because they may be made in any optional manner well-known in itself. In the normalposition of shaft 7 0 the rollers 53 and 72 are in recesses in the cams 5,9 and 71. If the shaft 70 is moved by striking the end-of-li-ne key or the line-canceling key, the rollersi 58 and 72 are forced out of the Irecesses in the cams 59 and 71 and cause the.

levers 34 and 49 to rock around their fulcrums 73 and 57, respectively. Lever 34 then draws the bushing 32 back. the ratchet 'teeth 44 of the crown wheel 45 being also` drawn back andwithdrawn from the crown vwheel 42 by means of the vlever 49. This crown wheel 42 is driven, during the backward .movement of the papercarriage and the wheels 11, 13 and 14, by the/stops 39 and 40 and likewisearrivesback into the position for the beginningof a line.

whenl the pawl .|151 falls into a gap in the crown wheel this diskiscompelled to participate in the rotation of the wheel. With the disk is firmly 'connected the auxiliary 'shaft so that this also must participatein the rotation of the wheel. In its position of rest the pawl is prevented by a, lever 1551frombeing connected with the crown Wheel, but

'when this lever is pulled away thepawl is connected with the crown wheel and .the auxiliary shaft rotates with the grooved pulley 148. :But before one rotation is 1invishedl, the lever 155 returnsinto its. normal position and a'slanting face 156 on the lever receives tliepawl ll'and lifts it out. of the teeth of the crown wheel.- The clutch which temporarily connects the grooved pulleysv .145, 146 witlrthe main shaft 78 is arranged in exactly similar manner. Opposite the crown wheel '1,49 is the pawl 160 which is under the action of a spring 161 and tends to engage in the teeth of the crown wheel The pawl is pivotally connected 164 supports the extension of the pawl 160 and prevents it engaging in the teeth of the crown wheel.

l Now if any key is struck, any one ofthe plates 10i-iis displaced. Be-

The latter is considerably .weaker than the silnultaneouslyacting; fifteen springs of the ratchet teeth of the .Wheel ,45. Consequently this Wheel remains in engagement with the Wheel flfrand theY latter isthe paper carriage comes to rest as soon as the stop 39 has reached the stop 40. The

cam 71, lever 34 and crown Wheel 37 actin the case of this -key exactly as in the case of the end of'- line key or in the case of the line-canceling key.- After the wordfcanceling key has been" depressed the paper carriageshould occupy that pos ition in which it was before beginning the canceled Word. To this end, when finish? ingr a word or when beginning'a new )word thestop 4U must pursue the stop 39 :1154i be at Voucc fixed ag'ai1'1. VVhenercr the 'word separating 'key 'is struck, the connection of thecrown Wheels-45 and -12 i's broken. For this reason the lever-'50' is rovided 4which coacts `with the flan e 4 8. T is lever can rock' a1"oundA a `Vpivot 5 and .carries at. one end a roller 76 lyingjagainst a cam 77. Theroller 7G is onv the i-nainfshat 78 of the apparatus n-'hicl1 .'is driven Whenever a'key is struck .and stops after one revolution. The roller 76 is `in a recess of the Cain 7 7 and Y is influenced bythe cam in Iikennanner as the rollers 58 and 72 are-influencedby the cams 59 and 71. however, onlywhen the Word-scparatinglkey is struck, because the pivot 'is secured,' like pivot 57i-ono sliding carriage r79f1novablc longit-u'(.linalty` to ivhose f ree ende lever 80 v`is p'ivotefh This'lever can rock around the pivot 81 and is1h`cld at 'its'loiver cud teni poraiily by a 'detcntor catch 82. #This catch forms the iend of-vu lever 84 rocking around pivot83 und attached at its other lend to a 115 lever with the shaft 86 of the word-scparafting'keyf l-Vhen any key other than the wond-separating key is depressedythe Shaft 78 is actuated without 'the lever 50 disenga ging the: crown 'wheel 43 fnom""the crown 120 Wheel 42, namely the-lever 5,0 rocks around its forked end, While` the pivot 75 and the slide ,79 reciprocate under-the action of the spring 87.

After the complete revolution of the main shaft 78 the'roller 7U falls again into. the recess iii thecam 77 and the teeth tlf-- airain enter into the crown wheel 42, so that this is again checked from moving fmith'cr. If, when canceling a Word, not onlyr this baty valso the previous' spacing element is to be canceled, the adjust-ment of the stop must be completed before the paper carriage is fed corresponding to the space. This can be broughtabout by snitallily shaping the cam 7 7. For example, the recess in this cam may ybe made so large that during that part of the rotation' of the main shaft 76 which Serves `for actuating the wheels 1G, 17, 18 and 19, the roller 76 lies in Ytherecess of the cani 77 and exercises no action von the lever 50.

The operations when using the individuall keys are as follows: ln the case of tht` eudof line key the auxiliary shaft' TO is coupled with the source of power, which operates the perforating apparatus. during one revo-lu ti `h ofthe auxiliaryshaft and is automatica ly disconnected therefrom afterl the {irstV revolution. The two cams 5f) and-Ttwtfht raw the teeth of the crown wheels 37 and 45 from the crown wheels 38 andl 42. In this manner both the wheel 1=t and also'the arm :l1 become free, so' that bothmore baekf ward ander-the influence-of the spring at. the papercarr-iage up to the beginning-of line position. The spring on the paper earriagc is not shown on theV drawings; it may he arranged aswell-known from ordinary type-'writersbut. with' the difference beforementioned, that it. must' move the carriage backwardly instead olf forwardly.l *ln addition, when the endlof-line key 'is struck .an end-ofline symbolis perforated. The per- 'forating devices for tlii'smaybe of optional kind and' are 'therefore not liereiu-described.

'When-the line-caiiceliiig-key is struck tl1c= saine action occurs', with regard to the haekwai-d niov'einent of the'papei carriage. as
