Atpiicanon mea April 25,- i910. sei-iai No. 557.2%.

T0 all whom i; may concern Be it linown that I, GEORGE VOELKER, a citizen of the United States, residing at St. Paul., in the coiinty of Ramsey and the State of ltlinnesota, have invented new and useful Improvements in Type-lVriting Machines,

which the following is a specification.

Mytinvention relates to typewriting machines and more particularly to means for controlling the time of printing operation, the invention being especially useful when dictation is tajgen on the machine. In such .work the dictator, desiring to change matter already written, requests the operator to X, or cross out, :the words to be changed.

The object of my invention is to provide 'means by the use of which the X-ing out of written matter is eliminated.

A further object of the invention is to eliminate the necessity of erasing when it is desired to change or take out matter already written; or of inserting matter between lines in .cases of `omission.

' 1-o the above and other ends which will front elevation of .showin-g a portion Fig.y` 8 is a fragmentary detail side elevation he features Aof construction, arrangement of arts and combination of devices to he set Aforth in -the following specifica-tion and particularly pointed out in the appended claims.

In the taccompanying drawings like reference characters indicate corresponding parts ,in Ithe various views.

There are various styles or kinds of typewriters. i have elected to show my inven tion on the well known L. C. Smith 8a Bros. machine, wherein the parts are normally at rest and the keys at the key board are the only power applying source. l do not, however, wish to be conned or limited to any particular style of machine.

My invention may be carried out in any key actuated machine. wherein the depression of a key results in an imprint on the paper of the character indexed on that key.

ln my invention, any hey in the keyboard can be made, by adjusting suitable mechanism, to perform the functions of any other ybar basket K.

previously depressed key or keys. Thus, for example, `inwriting tlhe words delayed 'action The mechanism having been adjusted to delay printing operation for a period of fifteen characters or letter` spaces (the space between words counting, for one) the depression of the key i-ndexed n will' actuatethe type 'd It will be noted from. the above that fourteen keys had been de' are provided whereby he can .instantly re`4 store the parts to their starting pointsand lie can again utilize the same fourteeny letter spaces as he may see fit.

The, rock 'shaft V jou-r- 175 naled in the frame A is the usual tabulator key support, haring a downturned crank arm pivotally connected with link 1W, which leads to mechanism at the rear of the machine for the purpose of releasing the car- 8 0 riage. The levers X are substitutes for the l usual levers X shown in dotted lines il Fig, 1. It is not deemed necessary to further describe the above usual typewriting mechanism, except so far as a more detailed de- Iscription may be necessary to understand the' relations of my invention thereto.

Referring to the drawings, 2 represents ward' of the main body of the machin-e and are pivotally mounted on the shaft 3, said shaft having a fulcrumed lever 3a fastened at each of its ends. The le'vers 3aL are fulcrumed in the frame A and pivotallyV con nect at their outer ends with a rod 3", said rod having eccentric pivotal connection 3c with the bail 15. Each key lever has a retaining spring 2to hold it normally against the edge 2b of the wall A of the frame A. The key levers 2 extend forwardly in a horizontal plane' across the-entire keybardand end'in close proximity to the spacing key 4. Each' key lever is paired with one of the type bars of the machine. Intermediate of its length each key lever has an offset, the 105 shoulder, thus formed, terminating in a downwardlycurved cam face 5. 'This'cam face engages the' top of the upwardly projecting linger 6 (Fig. 8) one of whicl'r-.S pivotallyf mounted on the end of each of they sub key levers R. The'spring 7 tendsto hold the finger disengaged from ythe bar 9 by pressing. it against the stop pin 8. The universal b ar 9, whichcarries a linger key 9a at one of its ends, extends laterally across the keyboard. andis ,above the vends of the sub key levers R. It is in a position oy engage the notches 10 in the fingers 63 hen said fingers are slightly moved about their lproject,through the vertical slottedihole 17 13 0 pivots, so as to rest against' it. Its ends pro'- 120' f in the frame A., which permits of the depression of the bar 9. The hail is provided at one end with a iat sided cam 1S, adapted to act upon the end of a slotted plate lll. said plate having two diagonal slots Q0 parallel to each other, through which pass looseljY the screws 2l into the traine A. i spring Q2 tends constantlv to nieve the plate toward the cani 1S. The eoniparativelj long slot Q3 inthe plate l?? is ol a size to loosely receive the anti'irietion roller ffl, the purpose of which will he more speeilirallj' hereinafter set forth. On one ol' the downwardly and forwardlj` projecting members of the universal har 9 are pivotallv mounted. a linger dog Q5 and a pa wl 2o. rl`he dog and pawl are separated h v a liloel; 22T. against the opposite sides of which each is pressed by the sjring 28. which tends constantly to llring thein together. The llog provided at its side with a finger plate 29. which projects through the hole ll in the trame The dog and pawl are each provided with a tooth 3l and respectively. iLirojectingr 'from their sides and toward each other. rl"ne tooth Eli? is above and overlaps the tooth fil. so that a slight rearward ino-feinent ot the dog will stretch the spring 2n and separate the dog and pawl. lt will he noted upon inspection ot the drawings. that the dog is adapted to engage at its top the cani 1S so that the turiiing of the hail lf3 will separate the dog and pawl as shown in Fig. 2.

Journaled in the sides ot the traine A and parallel to the har d are the shattsill and Si. upon each ol which is rigidly mounted an oetagonal roll 35 which Yfor reasons hereinalter explained will also hereinafter he terred to as jaei'piarl carrie The shaft il passes through the traine and has at each end a thunih nut 3o. "l`he shalt at one end and rigidly' inoiinted thereon, a toothed wheel BT. which engages the pawl 20 when the hail l5 is in the position shown in Fig. l. Supporteiil at its tour corners 'oy the shafts 33 and 3l. hy means ot the journals 38, is a jacquard sujjiporting table 39. with its top surface level with the tops of the roll 35. Suj'iported to prevent sagging hy the tahle 3H, and tirinlj stretched over the rolls 35. is an e idless carrier or conveyer 40, also to he hereinafter reiterreigl to as an endless jacquard adapted to conform to the periphery of said rolls and to travel over them when the)v are turned about their hearings. For the purpose, of inovably holding the rolls positioned. so that each shall have two olt its sides in a horizontal plane, the clip #ll has a .spring l2 to pall it ae'ainst one side of the roll.

The, jacquard l0 comprises a series ot' comparatively long hollow sections .ll, preterably bent of one flat piece. and alternately punched and stamped as at stand l5, so

that it will mesh with its adjacent section and permit of the insertion o-a rod i6. thus forming a hinge joint as shown in Fig. T. rl`he sections 4.3 are as wide as the sides of the oetagonal rolls and are of suliicient height to contain the friction plate li' of the rain leal" itl. lt will he noted, that each of the sections lll. has in its top plate a series ot holes lfl and 50. The hole -ltl is spanned with the har fil upon which s ings the cani hat' ll". the frirtion plate i7 ot' which enters Yl'reelj' the hole 30, The cani leaf has at its top the curved ar 52, and on its face (which normally turned down) an index 525. which is identical with the type on its correspondinj,` type 'maar in the type basket K. The curved ear 5'! is concentric with the leaf hinge 52",. and has its underside painted lilacli to serve as distinguishing means to he hereinafter explained. as shown in Fig. 7. The friction plate l? stands at right angles to the cam leaf. of which it is an integral part. and is oppositelj' disposed thereto. lt trnetionallr engages the inner side of the side wall lll or the sections i3. so that the cani leaves will remain in an)v position to 'ahieh her may he turned. Rach cam leaf oi' eaeh row. troni trent to rear. is indexed on its under face with a character that corresponds to the ifharacter of a type in the type ha ind itsl corresponding linger key at the lieixioard. Thus for every character hej' at the lievhoard there is a longitudinal row ot rain leaves on the jacquard. said lea hiring also disposed in transverse roi For example the character e shown in Fig. T is represented hy the type e on a type har in the hasliet K. Thus, any coinhination oi haracters nia)v be selectively recorded on the jacquard `at the will ot the operator.

The barrier l0 and its cani leaves including the rolls 35 constitute a rotary device. and the cam leaves which actuate all the type actions when turned up majv he termed traveling indexes or settahle projections. Integral with the sides of the frame A, and extending rearwardly the full depth of the he;v hoard. are the racks 55. The pinions 56 inesh into these racks and are rigidlyY mounted on the shalt 57, said shaft passing through the horizontal slots in the frame A.. A thunih nut. 59 is rigidly mounted at each end of the shaft .5?. whereby the pinions ran he turned to cause them to travel hach and forth over the racks. The pinion shaft is rotatahlv mounted in the journals ll in the hase of the stand 6l, said hase loing formed with a lip adapt-ed to slide smoothlju in the groove (32 in the frame A. Journaled in the top ot the stands 61 and extending transversely across the hey board,

the time regulating har 63. which is hol- 1ow and rectangular in Cross section. At each end it has a-spindle 63*7 which rota- Itably fits in the journals 64 of the stands.

Onelof the spindles carries rigidly at its outer end a -crank arm 68 with the a11titriction rollerI 24 rotatably mounted in its outer end. A spring66 attached to the arm and stand tends constantly to pull the roller end .71, having at its lower.- en'd a shoe with an offset thus forming the two planes 72 and The upper. portion'of the bar 71 is round in 'cross se'ction and fits slidably in the tube portion65.V The round shank has at its base an inverted cup shaped collar 75. The collar serves as an abutment for the spring 76, itsl downturned rim 77 limiting the downward movement of the bar 71. It

,will here be noted that the tube isfree to be further depressed'after the lower 'edge ofl the. rim 77 is seatedupon the bottoni of the l bar 63.'v y

Rotatably mounted on the pin 7 8, on the frontface of the time bar 63 is the disk lever 'id lever'having pivotally' mounted on sk, by means of pins 80 and 811, the rods 82 and* 83, respectively. Theirodsy extend be ond lthe length ofthe bar 63', having suitab e mounting (as at f) to steady their ends 84. A .spring 83'A tends constantly to withdraw the ends. Theendsk are beveled and rest on similarly beveled lugs 85g said lugs bein integral with the stands 61. The lugs ,are ormed with two o'set horizontal planes the offset forming the bevel portion 86 shown in Figs. 16 and 23. y v

Preferably integral with' the bar 63 is the lug 87, wh'ich slidably supports in vertical osition, the stem 88 which engages w1th its ower end the upper Iedge of the lever 7 9. AT pin 90 fastened in the stem 88 slides 1n the vertical slot 91 in the bar 63 and in the inclined slot 92 in the plate 93. The pin passes through said slots into the interior of the bar 63 and is formed with a head 94, so as to hold the plate 93 slidably against the kinner wall'of the bar. The plate 93 isy formed at its lower edge with a rearwardly extending flange 95, which` slides longltul 'dinally of the bar 63 when the stem 88 is moved in its support. The stem tits snugly in the lug 87, so that it'will retain any' position to which1 it may be moved. The slide 67'has on the flange 69 of its tube port1on 65, a pin 97, which passes through the ver- .tical slot 98, in the Ifront wall 4of the bar 63. The piny 97 engages tlie upper edge ofthe- 'nism to be hereinafter described.

direction to the left as shown in Figs. 12 and 13. These ends engage the forwardedgcs of the cam leaves 18, 'and serve to turn them down, from up position, .when the carrier il) is caused to travel in forward direction by turning the nut 36. The teeth 103 of' the lower'row also extend rearwardly and are bent downwardly and from the rear forwardly,| the downturned portion leading in an oblique direction to the left. These teeth also serve to turn down the upturned cam leaves on the carrierby engaging the rear edges of said leaves when the carrier is moved rearwardly as is shown in Figs. 1, 10 and 11. Thus the ram leaves, which may also be termed indicating actuators are returned from operative to inol'ierative positions by means of said combs, the leaves being operated when upturned to indicate C which keys have been depressed and to actuate through `the moving jacquard, mecha- On the right hand side of, and on the frame A, is adjustably mountedva reflector LZ, having hinge connection 106 with the pivot plate 107, said, plate swinging in a vertical plane about the set screw 108, whereby it can be adjusted and clamped firmly against the side of the frame. The rellector has a mirror`10lA with a'hinge 105 at its top. The hinge 105 is tight fitting so that the mirror when tilted will remain so. It can be tilted so that it will reflect the' character on the cam leaves, as they are passing, on the jacquard through the opening bbb at the right of the machine between the key levers 2 and may be arranged to suit any style. of may chine,thedrawings'showing a tabulator key or bar 110, a spacing key or bar 4, some character `keys 109, and a special key 9.

yEach key, excepting. 9axis mounted on a key lever 2, the tabulator' and spacing bars being shown mounted on two key levers each. The key levers are arranged in pairs, (Fig. 24) one main lever2 above, and a sub key lever R below, with the coperating finger 6 between them. These levers and fingers aline with one of the slides 67 and with a row of cam leaves 48, so that'when one of the keys 109 ,is depressed. the lever '2 engages the slidellt? and pushes it down. 'the slide, by means of the planes i12 and T3 of itsy shoe, will engage and press down the friction plate $7 of one of the cani leaves, and thus turn it on its hinge 33, setting the leaf in upright position (Figs.l 5, t3 and T). Thus the key levers with their liefs and the slides constitute key actuated devices for setting up type indexesor cams. Also the cams or indicating actuators, supported on the llac quard whereby they are bodily moved. constitute a portion of the actuating devices for all the type bars, since no type bar can be actuated to print without lirst becoming connected with the levers ll through the actuation of the cams or actuators.

Upon inspection of Fig. S of the drawings, it will be seen that if the key lever 2 be depressed to the position shown in dotted lines, the top of the finger 8 will slide rearwardly on the cam face 5 until the notch .lll will have engaged the bar 9; a further 'depression of the key iever will aetnate the sub key lever R, and thereby the type bar J to print an impression of its type.

The linger 6 and the bar 9 constitute a cobperating means, or connecting means, be-

tween the key levers and the typewriting instruinentalities, said means being controlled by the cams 48, and the carrier l0 which in turn` are actuated by the key levers.

To permit of the depression of the key levers :2 (Fig. to the position indicated by the dotted lines, the bail 15, and the time bar 63 must be turned on their sides, as shown in Fig. 2, wherein the p-.rts are shown in position to do direct writing, as in an ordinary typewriting machine.

It will be noted that the oscillating ol' the time bar ll carries the depressors GT with it and thus places them out of the path of the key levers 2. The turning of the bail l5 from the position shown in Fig. l to that shown in Fig. aifords a clearance between the levers .2 and the top of the bar l). This clearance permits of snliicient `downward movement of the levers 2 to cause the lingers 6 to engage the bar 9, thus constituting automatic engaging means.

From the above it will be seen that when Lhe slide (5T in Fig. :2i is in the position shown in dotted lilies, the depression of the key l0?) shown indexed with an i in the drawings, will actinite the type liar J and *anse itito print an lY n" an impression of its type. This is direct 'v-uriting.

For the purpose of delaying printing operation of any of the type bars until some time after its corresponding key in the key# bear-fl had been depressed. the engagement of the bar 9 with the fingers 6 is delayed in the following manner:

Referring to Fig. i), it will be seen that the pawl Q6 is held out of the pt th of the toothed wheel 37, by the cam 1S which shown engaging the dog 25, and thereby controlling the pawl as has been hereinbefore explained. ylhe depression of the bar 9 will carry the dog and pawl with it, the fiat sideI of the cani le sliding on the rear end of the plate lil. To set the mechanism of the de laying, or time element as it will hereinai'ti-ir be releri-ed to, it is necessary, only, to turn the thumb nuts lo and 59. The turning to the right of the nut iti on the left side of the. machine wil move the parts from the posi* lion shown in Fig. to that shown in Fig. l. 'lflie cani 15, when turned to the right, will rebase. the dog 25 and pawl Q6, so that they will be drawn toward each other by the spring The pawl will now engage the toothed wheel 3T. turning said wheel a partial revolution. or letter space with every return or upward stroke of the universal bar t). On the downward stroke, the pawl t) will. ride over the teeth of the wheel. Thus the carrier lll. through the turning of the .vheel 3i' and therefore the shaft 33 and roll 33, will travel horizontally and rearwardly, in a step by step movement, the speed of its travel being controlled by the activity of the keys.

Any cani index leaves that may be turned up or project from the surface of the jaequard, will, in turning over the rroll 35 (Fig. Si act as cam teeth to actuate the lingers il and push them into engagement with the universal bar l), The lingers (i constitute jacquard actuated devices. The depression of bar il by the invierator after such engagement will actu-ate the typewriting instrumentaliiies. The return stroke of the bar l) will canse thc pawl to turn the wheel 3T gust sullicir-nt to permit the clip l-l. l. l1" f. 12) to enj; gc the next s cceeilirng llat sine of the iolls 23.3, inns controlling with exa-etness, the step by step movement ol the carrier and its relative position with the depressors (3T. The turning ol' the niet lll, will cause the cam to release the plate il?, `which will more rearwardly and downwardly, by virtue of the spring 22, the slotted hole 2l) and the screws 2l.. Aln its downward travel, it will carry the roller 2i with it, and thereby oscillate the time bar (53. The time bar will thus be turned to the position shown in Figs. l and, iT. ,so that the ilel'iressors (i7 will stand upand aline with the key levers 2y and the cams. 'l`he bail l5 has eccentrically pivoted in its ends. the rod 3, which pivotally connects with the fulcrunied lever When the haii is turned up by means of the nut lo. it also actuates the lever il through the rodv fl. 'thus moving rearwardly, the shaft 3 and therefore all the key levers Q hung on it. This rearward movement of the key levers, when the time element is being set, causes the levers 2 at, to clear the tops of the iii gers 6 as shown in Fig. 25, that the de lll? alinement with it. Thus, the depression of any key or key, lever will simultaneously set.

up one of its corresponding index cam leaves,

and dep'iessy the universal bar 9, thereby.

actuating to print, any type barwhose key lover it with its linger 6 had been previously brought int-o engagement with the bar' 9. lYhen the 'fingers (hare disengaged from the bari), the key levers 2 are .rendered independent, irrespective of their indexes. The return stroke .of the' bar 9 turns the carrier to travel as has hereinbefore' been explained, thus releasing the ringer 6 which will spring 'ba'ck against the'pin e, at the same time disengaging the cam lea v.es from the liingels 6. As the upper run o the jacquard travels rearwardly, the tipturned' leaves, as they turn oter the front oi' the roll 35, from below upward, are wiped down to' their normal position by the teeth -103 of the lower comb. lt will be evident from the above, that the time at which printing operation occurs, after a key has been depressed, depends upon the location on the carrierotl .the point ay which thev leaves are turned up. llietim of printing operation'is,therefore,

controlled by the shiftingv of the time bar 63. It for example a leaf be turned up at a pointnear the `front roll, it will' have to,

travel the entire distance to theiinger 6, before it can engage the typewritmg instrumentalities toieti'ect a printing operation.V

y1n Eig. 2 this distance is shown to be about thirty letter spaces, or more than half of 'an ordinary line. "Thus, inwritin'g thirty characters, the depiession of thethirtieth key will begin to print'on the paper, theirst ot the thirty letters. It .vill be evident from the above, that twenty nine keys had'been depressed without writing anything 'on the paper. lf the operator desired to change these twenty nine letters'on an ordmary typewriting machine, by erasing, much time would be consumed and the work would prey-y sent a soiled appearance.`

In my invention, the operator, desiring to change the twenty-nine letters, proceeds as follows: lVith one hand the finger niece 29 is pressed rearwardly, thus disengaging the pawl Q6 from the wheel 87, and with the other hand the thumb nut 36 is turned to the left or in the direction yto cause the top run of the jacquard to travel toward the front. The upturncd cam leaves, represent ing the twenty-nine letters will be wipedV down, as they'engage vand pass the teeth 101 of the upper comb. By looking'in the mirror 104 the operator can, at all times, see

legibly reflected, what he expects to write, affording opportunity to detect errors or make changes. yThis capability of retrieving depressions-of keys, without printed results, is especially useful in taking dicta tion on the machine, wherein it is very desirable to avoid To change the period yof delay of printing operation, the. operator turns the thumb nut '5,9, which will cause the pinion 56, through the shaft 57, to travel in the racks 5. The pinions, will carry with them, the stands 61 and -therefore'the time regulating bar'63.

T'hus, the| delay may be set 'for a Single letter 75 space or a plurality ofiletter spaces. The carrier with its leaves andthe time bar constitute, therefore, a time .element, whereby the type barsy ofa typewriting machine can be controlled to perform their functions at 30 predetermined times.y Likewise, the bar 9 and 'the fingers 6, constitute a neral cou.- pling ppint, where the key levers are coupled with their corresponding or any of the other` type hars, and toward Iwhich the' carrier 35 travels gr'eater or lesser distances to consume time and-thereby delay type action.

The carrier, with itsI indexed leaves on which the characters are represented'back' wardhso that they :will be legible in the re-.` `iector d, constitute, with, the reflector, a dis'- playing 'device or a work indicator. The bar 9 and thejfingersat the rear of the keyboard, constitute a cooperating means between the typewriting instrumentalities and '95 the keys; they also' constitute a means for interchanging the| operative connections be-' tween saidI instrumentalities andkeys. The thu-mb nut 16 and the chain of mechanism connected therewith, which serves to move the bail 15 and the bar 63, as well as the le.- vers 2. constitute a means for rendering inoperative or operative the delayingdevices, or a means for restoring direct operative ,eonnecti on between thel keys and their type.

It will be evident that whateverlinumber ofletter spacesl the delaying'devices are set to, the work in hand will be lacking that number of characters on the paper to ren-4 der it complete, when they last character of the work in hand hashad its key depressed. The lacking characters still have their corresponding cam leaves upturned on the carrier.

Ty print these lacking characters to complete the work without turning up any more ,cam leaves the operator repeatedly depresses the key 9aon the universal bar 9 until'every one of the remaining upturned leaves have passed. the coupling point', or, in'other words, caused an imprint to be made.

the lower case letters. To distinguish capitals from small letters on' the indicating device, mechanism is provided to tilt the leaves Y as shown in Figs. 6 and 7, wherein the uli-'.125

It win be noted that the cam leaves are indexed with a capital. The turning,r ot the. leaves past the vertical by the depression of either the shift or shift lock kiv is accomplished as follows: The slides ur .'lepressors (37 and 6T aline 'with the. ker levers 2. carrying tho shift lock and shii't key" keys respectively. `l'lien the shit't lock key is depressed, the stein this.

The. turning of the disk Yiev er TJ (.:Xtenrls the rods 82 and S25 lengthwise. causing their beveled ends Si to ride on the bevel surface SG. and thus tilt tl'ie. bar ful as shoun in Fig'.v i8. This oscillation oi'fthe har (33 with the slides7 moves the 'plane 7; over the friction plate 4T ci the cams.

When the shift key is used in the usual Way, or, in other. words, to shift the type basket for one ii iprint, its pin 97 in its downward movenient will engage and turn the lever 79 on its pivot and thereby tilt the time bar momenta ril v, the bar assuming its norma-l position hen the shift key is released from pressure. rFlins. vvhen the Shiftkey is depressed to unlock the shift lock key,the cam leaves. which the shift key turned upwhen it was depressed, will stand as shown in Fig.`5; but when it has been depressed for other purposes than the unlocking of the shift lock7 key. the cam leaf it turns up will stand as shownin Fig'. 6. Thus the leaves will indicate in the reflector Whether the shift key had been depressed for the purpose of unlocking' or for the purpose of shifting the basket. to print. This shift lock and shift key mechanism constitutes a secondary type shitting: and shift locking mechanism. In use the operator, desiring to delay printing oper-ation. proceeds to turn the thumb nut lo until the bail 15 is in vertical position. lle then sets the time element by turning the thumb nut 59. and proceeds to write, manipulating the keys as on any ordinary Writing machine. ll'hen he Wishes to Write direct. he simply turns the thumb nut 16 and each type bar `will respond to the depression of its key. A

lt is obvious that the details of the device univ he variously modified without departing from the principles of the invention. the scope of which is defined in the `claims.
