Specification of Letters Patent.

Patented 'Allg12431920 Application filed September 1o, 19'11s. Serial 1ifo. 2 5 3,368.

To all whom it may concern: j l I Be it known that I, Jenn YVALDHnrM, a citizen of thellnited States,.residing in Elizabeth, in the county of Union and State of New Jersey, have invented, certain new and useful Improvements} in Typewritinglvlachines, of which the following is a speci tication. Y

li ly invention relates, chines of the class wherein a plurality of separate and distinct printing mechanisms or devices are provided, any one of which may be operated by a single set-of key levers and from a single key-board, so that a plurality of tents of type differing in style troin one another, or fonts of type adapted for writing in two or more languages, are available for use in the same machine the machine being capable of adjustment in such a way that any one of the printing mechanisms may be used at will." The object of my inventionis to provide certain improvements in; machines of this type, and wherein the printingdevices; are unitary structures insertible into and removable fromthe machine as a Whole and at a single operation, whereby the number of kinds or styles of fonts oftype'usable in a particular machine is unlimited; this in vention' being an; improvement upon the typewriter disclosed in'my' co-pending" application filed March 20, 1918, l\o.. 223,489, v A plurality of printing devices, preferably in the form of type-sets, compriseeach' a type-bar. supporting segmentcarrying a plurality of pivotally supported type-bars, the said printing devices being supportedin fixed relationto oneanother by 'a movable, member supported from the frame of the machine; said printing devices beingreadily detachable as a whole and as unitary structures from the movable member whereby they, are supported, so that any one or all of them maybe removed from the movable member and other printing devices substituted therefor; thus providing for the'use of. any number of printing devices and any number, of stylesor kindsof fonts or type in a single machine. y

The movable supporting member provides for the movement of any one ofthe print ing devices,which maybe supported by it at any given time, into a position such; that it will'typewrite properly upon a work-sheet to typewritingmasupportedfby a carriage carried by the ma-C chine,;"all the printing devices being adapted to printat .one and the same point; and

'means are provided for locking the movable member in positionssuch that anyone of the printing devices carried thereby will be roper position for, typing upon the wor esheet.

The movable support ng member erably in the-form or a barmovable in the direction of itslength along suitable guides carried by the frame'o'f themachine; and the said bar carries brackets whereby the, printing devices are supported, and the construction of which brackets is such that any prlnting device may be readily removed from the machine and another substituted therefor. Said bar is also provided with a rib having notches orrecesses spacedapart from one another and adapted to beengaged by a swlng'ing locking pawlto thereby lock the bar in positions suchthat theiprin'ting device selected for usevwill print properly upon the work-sheet; the, end portions of said rib being higher than the middle portion and forming stops forlimiting the normal movement of the bar. The locking pawl may, however, be swung into an ex-i treme position in which it will clear the end portions of the rib, thus permitting a furth'er movement of the bar in order to carry the type-sets supported thereby beyond and free fromthe frame ofthe machine to thereby facilitate their f removal from the supporting bar, and in'order that the frame may not interfere with the substitution of one printing device forv another. 1

Each printing-device preferably comprises an upper type-barv supporting segmentwhereby a plurality of type-bars are pivotally supported; i a lower crossb'ar whichserves'as'a support for a plurality of pivotallyu. supported typebar operating members operatively connected one with each of said bars and connectingside portions whereby said cross-bar and segment are connected together, whereby a unitary type-set, removable, in its entiret' andjas a single structure from the movab e supporting bar, is provided; the side portions of the r type-sets carrying means whereby they are supported from the brackets carried by the bar in such a Way as to be readily detach able therefrom.

A single setof keylevers is provided foroperating all of the printing devices with which a machine may be equipped or which may be used'therewith, said key levers be ing provided with means whereby they may be'operatively Connected with any particular printing device selected for use. In the embodiment of my invention illustrated, the key levers are provided each with a connecting member pivotally connected therewith, and the free ends of the-connect ing members are provided with pins adapted to be moved into and out of engagement with slots formed in the type-bar-operating type-set and unlock the movable bar, whereby thetype-sets are supported, thus leaving the bar and type-sets carried thereby disconnected from the key levers and unlocked from the frame of themachine, and free to be-moved to bring another type'set into position for use. i 1 i i A single escapement mechanism is provided, the same being supported from the -main'frame of the'machine and operatively connected with the carriage thereof. Each type-set, however, is provided with an individual universal bar, and the single escapementmechanism is operated by the universal bar of the particular type-set in use at a given t me; motlon'bemg transmitted from the universal bar to the dogs of the 'escap'ement mechanism through a reciprocating pivotally "supported inter mediate member adapted to be engaged by any oneofsaid universal bars, and which in turn is'in engagement with the dogs.

Suitable mechanism for supporting and advancing a'ribbon, and for 'shifting'a por-' tion thereof in unison with the platen as v the same is moved into its upper and lowercase positions, will also be provided; the ribbon mechanism comprising vertically shiftable ribbon-vibrating members carried one by each of the type-sets'and adapted to move the ribbon into the path of a type as it approaches the platen, together with operating levers, one associated with and adapted to. operate each ribbon-shifting member; the said lastmentioned levers being carriedby the platen-shifting mechanism, and motion being communicated to them from the universal bar of the particular type set in use at a given time through operating lever being thus always associated with its own type-set and 'operatively connected with the ribbon-vibrating member thereof, although only the lever and ribbon-shifting member associated with the type-set in use at a given time are then in actual operation; one only of said operating levers being connected with and operated by the said reciprocating intermediate member at the time in question.

In order to provide for the convenient and ready removal of the type-sets from the machine as unitary structures, the connections between the ribbon-shafting members carried by the type-sets, and the levers which operate the same and which are permanently associated with the machine, are made readily separable as the type-sets are removed, preferably by providing a slot at the free end of each operating lever into which a pm at the lower end of the ribbonshi'fting members may enter. The typesets as a whole are supported from the movable bar or other supporting member whereby they are carried by brackets earmember ried by the bar and having slots adapted to receive pins carried by the side members ofthe type-sets, a suitable locking member or device being'provided for locking each type-set to the supporting member to which it is secured and whereby it is carried.

"Other features andv advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a view showing my improved typewriter upon a vertical, centrally located plane'extending fromthe front to the rear thereof.

Fig.2 is a View showin ribbon-shifting mechanis 1 Fig. 3 is a skeleton perspective view, showing the principal operative elements of myinvention.

r Fig. 4 is a view showing a locking member for securing a type-set to its supporting member. V

Fig. 5 is a view illustratingthe universal bar of a type-set, and the guiding mechanism therefor.

Fig. 6 is a fragmentary front elevation g detail of the illustrating the relation of the removable type-sets to the main frame ofthe' machine, and showing one normal position of thesupport therefor as well as an abnormal position assumed by the support when a type-set is to be removed from the machine.

ig. 7 is a fragmentary view illustrating ent type-set. icferring to the drawings, the reference numeral 10 designates a suitable frame whereby the various elements which form my improved typewriting machine are supported in proper relationwith one another, the same having upwardlyextending standards 11 atits' rear end which serve as supports for a rear carriage rail 12 which supports the rear end ofa traveling carriage l3, and for an oscillating rod 14 to which two arms 15 and two members 15, for shift ing the platen 16 vertically into upper and lower-case positions, arese'cured'; the said platen being supported in a platen frame having end plates 17, and the front end of the carriage having a roller which runs along a front rail 18 carried by upwardly-extending standards 19 at the front portion of the framework. The two arms 15 are located near the standards 11. A shift bar 20, along which runs a roller 21 operatively connected 'with the cnd'plates 17 is supported at its ends by the members 15, which are located some distance outside of said arms 15. The arms 15 may be operated by upwardly eX- tending arms'22 at the rear ends of shift levers 23 pivotally supported from a crossbar 24 located at therear end of the machine, and which shift levers are provided withshift keys 25 at their forward ends and located 111 the keyboard of the machine, two such levers being employed, one engaging each of arms 15.

Supportedlb the. frame of the machine and preferably located nearthe rear end thereof is a guide shown .as comprising two guideways 26 spaced'apart from one another and having eacha Vshaped groove as best shown in Fig. 1. of the. drawings, and 27 designates a bar havingcorrespondingly V- shaped'grooves and which bar is movable between and longitudinally of the guides 26, suitable balls 28 being ordinarily interposed between'adjacent pairs of grooves'in order to reduce friction, as will be appreciated. The bar 27 is provided with forwardlyextending arms 29 located one at each end thereof and having bearings at their free ends, and 30designates vertically-extending shafts supported in said bearings, and the upper ends of which carry ribbon spools 31 which support a ribbon 32. The lower ends of the shafts 30 are provided with beveled gears 33 which mesh with beveled gears 34 of the frame H p (The several type-sets upon a horizontally-arranged ribbon-feeding shaft 85, through which the vertical shafts 30 may be operated to thereby wind the ribbon from one spool to the other, it'being understood that there is an arm 29 at each end of the bar 27, Fig. (i, and that a spool shaft 30 is supported in bearings provided at the forward end of each arm, although only one of said arms is shown. V

The longitudinally slidable bar 27 also carries a plurality of pairs of supporting bracketsdtl extending forwardly therefrom, as many of suchpairs of brackets being provided asth'erc are type-sets or equivalent printing devices to be supported from the bar 27. ,In the embodiment of my invention illustrated, two printing devicesin the form of type-sets are provided and which are designated. as a whole by the reference numerals 37,, Fig. 3, although more than two print ing devices maybe provided for should it be deemed. necessary or desirable to do so, all of said devices being supported from the longitudinally movable bar 27 and'moi able' therewith, as will be appreciated.

The type-sets 3? each comprise a type-bar supporting segment 38 which carries a plurality of type-bars 39 pivotally supported in slots 40 formed therein, and two depending side portions 41, the lower ends of which are connected with one another by a cross-bar 42, Fig. 3; said. cross-bar 42 being provided with a plurality of slots 43. within whicha plurality supported, one such lever being 'operatively connected with each type-bar 39 through a pin-and-slot connection 45 at the upper end of said lever, as best shown in Figs. 1 and'S of the drawings;

37 are eachdetachably connected with the sliding bar '27 through and by means of the pairs of brackets 36 above mentioned, to which end the brackets which form each pair are provided with slots 46, 47 and the end members 41 of. the type-sets with pins 48 adapted to enter the lower slots 4-7 and. the upper slot 46 of the bracket'which supports the inner one of the side portions 41,Figs. 1 and 6.

The outer end members of the type-sets are provided each with a slidable spring-pressed locking member-49 having a beveled head 50 adapted to lie ina correspondingly-shaped.

recess provided at the inner end of the upper slots 46 of the brackets which. support the outer end members 41, as best shown in Figs. 4- and 6; whereby when a locking member 49 is forced inward the. beveled head 50 thereof is moved out of the recess in which it normally lies, thus permitting the type-set with which it is associated to be swung forward, upon the lower pair of pins 48, as shown in Fig. 8, and removed from the supporting bar 27 and from the machine by lifting the pins 48 out of the slots 47'. Any

, type-set or all of them may be thus removed of a pawl 57, Figs. 1,

from the machine, and other type-sets difi ering as to the character or styleof the type carried by them may then be substltuted for the sets removed; or type-sets adapted to typewrite in a different language may be substituted for those removed; a single machine bein capable of operating with any number or type-sets, as will be appreciated.

T he bar 27 is stead ied in its movements and binding between the same and the guides 26 in which it moves, due to the-offset arrangement of the typesets and ribbon-supporting mechanism, which are ordinarily located to one side 01 the vertical plane of the barand guides, is reduced, by the use of brackets 51 carried by the said bar and extending below the lower guide 26, and carrying rollers 52 at their lower ends; whiclrrollers move in contact with a stationary rod or guide 53 supported from the frame oi the machineas the bar and the type-sets car.-

' ried thereby are shifted relatively to the frame of the machine.

The reference numerals 54-, see Fig. 7, designate two recesses or notches formed in a rib extending from the rear side of the bar 27 and spaced apart from one another, the middle portion 55 of said rib being of lesser height than the end portions 56 thereof, the purpose of the said notches being to lock the bar 27 in whichever one of the extreme positions into which it may be moved; the location of said notches being such that when the bar is locked, as aforesaid, one or the other of the type-sets carried thereby will be in proper position for typing upon a work-sheet carried by the platen 16. a position such that any one of the type-sets The locking of the bar 27 in maybe used. may be accomplished by means 7 and 9, movable into and out of the notches '54, said pawl being carried by a shaft 58, the ends of whichare journaledin the frame of the machine. S ecured to this shaft 58 is a depending arm 59, the lower end of which is pivotallycon nected with a link 60. The forward end of this link 60 is pivotally connected with the lower end of a lever 61 pivotally mounted'at 62 on the frame of the machine, and the upper end thereof extends into convenient position where it may be manipulated by the operative, so that as the upper end of said lever is swung backward on its pivotal support .62 motion will be commnnicatedto the pawl 57 throughthe shaft 58, and the free end of said'pawl will bemoved out ofwhichever one of the recesses 54 it may then he in, whereupon the bar 27 andtyp e-sets carried thereby may be moved sidewise along the guides 26 and itfilll'felGTlt type-set brought into position for use.

In shiftin'gfrom one to the other of the two type-sets, which at any giventime may be supported and carried by thebar. 27, the

pawl 57 need be moved rearwardly only far enough to clear the lower middle jpor- \Vhen, however, it is desired to removeone of the type-sets carried by the bar, the pawl 57 is moved rearwardly to a greater extent -Fig. 9, and to an extent such that it will clear the higher end portions 56 of said rib. This permits the bar 27 to bemoved to a greater extent than it is normally moved, as shown in dotted lines in; Fig. 6, and to an extent determined by a stop 56? which cooperates with the pawl 57, so that thetypeset-to he removed will be cle'arof the forward upwardly extending standards 19, whereupon the same may be released from the upper slots 46 in the brackets 36 and swung forward and removedpfrom themachine, as shown in Fig. 8, preparatory to substituting a different style of type-set for the one removed. When desired, recesses or notches 54 may also be provided in end p01 tions 56 adjacen'tstops56, so as to enable bar 27 to .be locked in position while typesets are being inserted and removed.

Located within the space 63 of the frame of themachine ,is the keyboard, the same comprising a plurality of key-levers (34 having operating keys65 at their forward. free ends, and the rear ends of ally supportedffro'm the framelofthe machine in the slottedbar 24 hereinbefore re} ferred to; springs 66, one foreach key-lever,

being provided in order to keep the same-in means are provided for operatively connecting the set of key-levers with whichever one of the plurality of type-sets the operator may desire to use. The connecting means employed in the embodiment of my invention illustrated in the drawings comprises a plurality of intermediate operating links 68,

one for each type-bar, the lower ends of said links being pivotally connected with the keylevers at 69, and the upper ends thereof being operatively and etachably connected with the type-bar operating levers 44; to which end the said levers are providedwith forwardly-extending portions provided with which are 'pivot-.

slots 70 into and out of which pins 71 carried by the connecting links 68 may be moved. I i V Movement is imparted to the intermediate connecting links 68 to move the pins 71' into bail 72 which lies in slots73 providedin the intermediate links;,the said bailibeing movable to thereby simultaneouslyswing all the said links about their pivotal connections '69 and move the pins.;71- into and out of; gagement with the slots 70. This bail72 is supported by an oscillating shaft7-1supported in bearings provided in the frame of the machineby means of upwardly-extending arms 75 located one at each end thereof, and the upperends of which arms carry said bail. One of the arms 75 is provided with a forwardly extending portion 76, see Figs. 1, 3 and 9, having a headed pin 77 at its free end; which pin extends into a cam slot :78 provided in the link through which the locking mechanism for the bar 27- is operated. This slot 78 is of such a form as-to produce a forward movement of the bail 72 as the link 60 .is moved forward by means of the lever 61, which forward movementof the bail will swing the set of intermediate links 68' forwardlyabout their pivotal connections 69; from which itfollows that as the lever 61 isswung upon its pivotal point 62, the pawl 57- will bemovedout of one of thenotches5t, and the pins 71 of the links 68 moved simultaneously out of the slots 7 0 of the type-bar operating levers 44, thus disconnecting the key-levers from the typeset whichthey have been connected with and freeing the bar 27, so that the sameytogether with the type-sets carried thereby, maybe moved sidewise by a finger-piece 67 extending forwardly from the slide bar 27. This releasing movement disconnects; the key levers from the particular type just pre viously in use, and permits anew type-set to be moved into proper position forguse, whereupon, and as the lever 61 returns to itsoriginal position, the pins '71 will 'be moved back into engagement'with the slots of the type-bar operating'levers44 of another type-set, and the pawl 57 will enter the second notch 54, thus locking the bar27- in position'such that thewsecond type-set is in position for use; 7 1 H i w Supported by the frame of thermachin'e' is V a bracket 79 which, serves as a support'for an escapement mechanism, 1 whereby i the V movement of. the carriage 13 for letter spacing is controlled, and-also as a support for meanswhereby said escapement mechanism .is operated by alnd vfrom the type-set in use at a given time. .1 j

The escapement mechanism is illustrated as ofa common'e type used in the standard {Underwood typewriter, and as comprising an escapementwheel 180 connected (bytheusual :one-way pawls, not shown) with a pinion 81 in engagement with a rack 82 carried by the carriage, the carriage being moved by'a suitable spring drum, not shown,

and the step-by-step movement thereof being controlled by a pair of dogs 83,84 carried byra dog-rocker 85 also supportedby the bracket 79.

The dog-rocker '85 is operated by anin ter mediate reciprocating operating member 86 having a bar 87 which engages the: dogrocker .85, and which member is supported by a link 88,the ends of which "are pivotally connected therewith and with the bracket 79, and'by spaced upwardly-extending arms '89, of .arocker 90 also supported fromth'e said bracket; said rocker having a depending arm 91, the free end of which is slotted, as at 92, and moves in slidingengagement with a bail 93 carried at the free ends of arms 94 located at the ends of an oscillating ribbon-feeding shaft 95, Figs. '1 and '2, supported in ears 96 shown as depending from 'two or 'more of the type-set supporting brackets 36. It therefore follows that the ribbonfeeding shaft 95 partakes of the longitudin al movement with the bar 27 ,"and that the, said shaft is operated from and by the intermediate reciprocating member 86 through the rocker 90, arm 91, and slotted end 92 thereof; the sliding engagement between the slot 92 and the bail 93 providing 5 a permanent operating connection through which oscillating'movement is imparted to the ribbon-feed shaft 95; I This ribbon-feed shaft carries pawls 97 which engage the toothed'periphery of a ratchet wheel 98 carried by the ribbon shaft 35 hereinbefore rc.

ferred to, whereby oscillatory motion imparted to the ribbon-feed shaft 95 is com-- municated to the shaft 35 and rotates the same to wind the ribbon 32 upon one or the other of'the ribbon spools31. 1

The machine may be provided with? a space-bar ear'riedby levers, therear endsof which are pivotally supported inthe cross-"- bar 24:, which levers will be operatively connected with an upwardly-extending arm adapted to-engage the arm' 91 depending from the rocker 90, to thereby operate the escapement independently of the key-levers, thesame asinmy co-pending case hereinbefore referred to, although these elements are not shown in'the drawings;

Suitable ribbon-vibrating mechanism is provided, the samebeing supported from the shift rail 20, whereby the platen is shifted, so as: to partake of the vertical movements of the platen'as it'is shifted'into its upper and lower-case positions, the construction of which mechanism. is as follows.

r Y removed to its replacement position, is out I Thereference numeral 99 designates two arms carried on-the shift rail 20, and which arms serve as supports for the ends of a rod 10 0,which rod in turn carries two vibratlng 'members in the form of bell-crank levers 101, one such lever being provided for each I type-set, although one only of them is shown; which levers slide along the rod 100 as the bar 27 is moved to bring either typeset into position for use. The verticallyextending arms of these bell-crank'levers 101 are provided each with apin 102, either of which pins may be moved into engagement with a slot 103, provided in an-upwardly-extending arm carried by the inter:-

porting segments 38 thereof; and in orderto provlde a separable operating connection between the said levers and the vibrating members 104, the aforesaid areprovided each with a slot 105, into which slots pins 106, carried at the lower ondsof the ribbonvibrating members 104, maybe moved, as will be understood-from Fig. 8; this detachable driving connection being provided in order that each type-set may be, moved out of operative relation with "the ribbon-vibrating lever 10lwith whichit is associated in removing the type-set from the machine.

It will be understood that the interme i diate actuating member 86 is located at the .middle of-the machine, and that the ribbonvibrator levers 101 are movable sidewise and relatively to said intermediate wactuatlng 'member 86 whenthe slide bar 27 is moved'to bring another type-set into eifectivere'lation with the keys. It will also be understood that anradditional sidewise movement is given to the slide bar 27 when itis desired to detachone of the type-sets so that it'may be :replaced by another When this addi-.

'tional movement is imparted to the slide bar 27, it will be seen that the ribbon vibrator lever 101,.associated with the type-set being of engagement with the intermediate actuatmg member 86 and-to one sidethereof: To

prevent the ribbon-vibrator lever from.

swinging about the bar 100-at this time, or,

in other words, to guard against the pin 102 from co mingout of alinement with the slot 103, so as to ascertain proper reengagement therebetween, the ribbon-vibratinglev i universal bars,

provided with finger 101--"which rests against the shift rail 20, F ig; 8.

The ribbon-vibrating levers 101 move vertically with the platen because of thefact that they are carried by the rod 100 which, asexplained, is carried by the shift rail 20,

during the movement of which the ribbonvibrating members 10 1 follow the platen, because of their connection with the levers 101 so that the ribbon is maintained in proper position relative to the platen as the platen is shifted, and when the same is in both its upper'and lower-case positions. When the platen is in either of these POSI- tions, the ribbon is moved up simultaneously with the movement of a type-bar toward the platen, because of the engagement. of a pin 102 in the slot 103 in the reciprocating inter- ;mediate member 86, which is operated by the typeset-in use; the movement of said mem- 101, associated with the type-set in use upon the rod 100, and thus shift the ribbon into the path of the type, when the platen is'in eitherits upper or lower-case positions The free forward end of each ribbon-vibrating lever 101 is guided in its vertical movements by guides 107, carried one by each of the type-bar segments 38, which guides,'because ber serving to rock the ribbon-vibrating'lever of their engagement with the levers 1101, act

to slide the latter along on the rod 100, whereby they are supported, as-the'bar 27 is moved to bring a type-set into position for use, and serve also' to steady the for'ward endsoffth'e shifting levers and maintain them in proper relation with the ribbonvibrating rnernbers 1041 operated by" them. The reference numeral 108 designates a universal bar, Figs. 1 and 5, one bar being provided for each of the'type-sets, and the same beingsegmental in form and operating in curved slots provided inthe rear faces of the type-bar supporting segments 38. These universal bars areengaged by the type-bars and moved rearwardly as the type-barsapp'roach the :printing'point, which movement is-tran smitted-to the intermediate member 86, to thereby operate theescapementme'chanisni'; to which end ea'ch universal bar is provided witha cross-bar 109,'1ocated in-line' with and adapted to engage the free forward end of saidiintermediate member 101;"Each universal bar -"is guidedand'-' maintained parallel in its movement by means of a rockshaft 110, supported in'lugs 111,"eXtending" from the rear face of- 'the' segment 38, and which shaft carriesftwo arm's 112 located one ateach 'end thereof, as best showniinFig. 5,

It therefore follows that as the universal moves rearward-1y, it is maintained parallel with itself in all positions, because of the bell-crank lever 115 and arms 112 and 114', which, in effect, provide two bell-crank levers, the shorter arms of which are connected together through the ment between each type-set and said set of key-levers,,so as t'obring any selected typeset and the set of key-levers into position to cooperate wlth each other, and means whereby said key-levers may be connected with or disconnected from the selected type'set while the latter is in cooperative relation therewith.
