Application filed November 26, 1386. Serial Ho. 345,078.

To all whom it may concem:

Be it known that I, STEFANUS NIELSEN, subject of the King of Norway, and resident of Van Nest, borough of Bronx, city of New York, in the county of New York and State of New York, have invented certain new and useful Im rovements in Type-Writing Machines, of which the following is a specification.

My invention relates more especially to the ribbon mechanism at typewriting machines.

in visible writing machines employing a ribbon it is usual to arrange the latter so that normally it does not cover the printing point and to provide means to automatically cause said ribbon to cover the printing point during printing operations and thereafter loreturn to normal position- One object of my. present invention is to provide a novel automatic crosswise ribbon feed operating in combination with the longitudinal feeding mechanism for the ribbon in visible writing machines.

Another object is to provide a construction wherein a ribbon having a plurality of printing fields may during printing operations be moved to cover the printing point with any desired printing field at will so that if the printing fields differ in character,

as in color or the like, any desired color may be employed.

Another object is to provide means to dispense at will with the crosswise feed of the ribbon in that class of machines employing a vibratory ribbon carrier and wherein the ribbon has a crosswise and lengthwise feed.

A further object is to provide means to enable a so-called polychrome or multicolor ribbon to be employed in the last named class of machines.

To the above and other ends the invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view of a typewriting machine embodying my invention, parts of the machine being omitted. Fig. 2 is a transverse vertical sectional view of the machine taken on a plane just forward of the top plate, parts of the machim being omitted and parts broken away. Fig 3 is an enlarged fragmentary rear view 01 the vibratory ribbon carrier, its support and part of the novel means or actuating said carrier. Fig. l is an enlarged fi'a entary vertical sectional view taken fore and aft of the machine and illustrating the ribbon car rier and parts of the novel means tor actuat ing the same. Fig. 5 is an enlarged frag mentary perspective view illustrating parts of the novel means for actuating the ribbon carrier as they appear when viewed from the rear and at the left of the middle of the machine. Fig. 6 is a fragmentary side view of the upper part of the frame ofzthe machine and showing certain features of my invention.

My invention is shown as applied to the machine commercially known as the Monarch typewriter, but it is to be understood that said invention maybe adapted to-other forms of writing machines.

Referring especially to Figs. 1 and 2 of the drawings, the main flame of the machine is shown as comprising the base 1,corner posts 2 and a top plate 3. Key levers a are fulcrumed on a fulcrum plate 5 in the rear of the base, each key lever being provided with a restoring spring 6 and having pivoted to it at 7 a sub-lever 8. Each sub-lever is slotted at its lower end portion at 9 to cooperate with a fixed abutmentl) and the upper end of each sub-lever is connected by a link 11 with a type bar 12 pivoted at 13 in a hanger 1a, the latter being secured by a screw 15 to a segmental type bar support 16. The hangers are arranged in segmental series and the free ends of the type bars are normally supported on a segmental type rest 17, said type bars being adapted when their actuating mechanism is operated to cooperate with the front. face of a rotary platen 18 which is diagrtically illustrated. The platen is mounted in a platen carrier or carriage {not shown) which is connected by a band or strap 19 with a spring drum 20 which tends constantly to draw the carriage leftward over the top plate. The carriage is controlled by the usual or suitable letter space feeding mechanism including a. vibratory dog carrier (not shown) which is connected by a link 21 with a lever arm 22 extending rearwardly from the middle of a rock shaft 23, the latter being pivoted at its ends on adjustable screw pivots 24. The arm 22 and the rock shaft 23 constitute part of the universal bar frame, the latteralso comprising side arms 25 which extend rearwardly and support along with the central arm 22 a universalbar proper 26, the

latter extending from side to side of'the machine beneath the key levers 4 and being adapted to be actuated when any of the latter or the spacing levers (not shown) are operated. The actuation of the universal bar operates through the link 21 on the letter space feeding devices, causing them to cooperate in a known manner to permit the carriage and platen to be drawn a letter space distance at a time toward the left by the s ring-drum 20.

Ri bon spools 27 are mounted horizontally above the top plate, one at each side of the machine and forwardly of the platen. Wound upon the ribbon spools and passing from one to the other in front of the machine is a ribbon '28, the one shown in the drawings being divided longitudinally into two fieldsor stripes a and 6 having dilferent characteristics; that is to say, the field a may for example be of one color such as black and the field bof a different color such as red, or the field a may be record ribbon and the field b copying ribbon. The spools are adapted to be rotated tow-ind the ribbon back and forth between them by any suitable means such as that shown in the drawings which corresponds with the usual ribbon feeding mechanism of the Monarch machine and will be briefly described. Each ribbon spool is mounted at the upper end portion of a vertical shaft 29 fixed to the lower end whereof is a, small beveled gear 30. Each gear 30' meshes with a beveled pinion 31 fixed to the forward end of a horizontal shaft 32, the latter carrying at its rear end a beveled pinion 33 whichis adapted to mesh with a beveled driving pinion 34 fixed at one end of a driving or power shaft 35. It will be understood that the latter carries a driving pinion 34 at each end and that it is shiftable endwise to bring said driving pin ions alternately into operative connection with their associate pinions 33 so as to drive one or the other of the spools 27 The driving shaft 35 is operatively connected with the spring drum 20 so that it is caused to rotate-by said spring drum when the latter is turned in one direction. The connections-between the spring drum and the driving shaft are of the usual sort and comprise a beveled shown) and which pinion 36 meshes with a beveled pinion 37 mountedon the driving shaft 35 and connected therewith by the usual pin and slot connection 38, 39 iii such wise that while the driving shaft may move endwise without affecting said pinion 37, yet any rotary movement of the pinion is always transmitted to the driving shaft.

Midway between the ribbon spools theribbon is threaded through slots formed in a vibratory ribbon carrier or vibrator 40 which is supported and guided on the upright arms 41 of a supporting bracket 42, the latter being secured by screws 43 to the top plate of the machine. The upper part of the vibrator may be of the usual style but the stem 44 of said vibrator is provided at its lower end portion as best shown in Fig. 3 with a horizontal slot 45. To cooperate with the vibrator 40 through the s1ot'45 I provide a novel form of operating lever 46, said operating lever being round in cross-section and slightly tapering as it approaches the front of the machine. The forward end portion of the o erating lever is off-set as indicated at 47 Fsee especially Figs. 1 and 4), and an extension 48 projects forwardly from the off-set portion through the slot 45 in the stem of the vibrator. The extension 48 is long enough to enable its forward end portion to be grasped by the operator and readily turned. The operating lever 46 is pivotally mounted on the frame of the machine in a manner presently to be described at length and from said mounting it graduallytapers toward its rear end, as shown in Figs. 4 and 5, terminating in a ball-like part 49 which is adapted to cooperate with a socket-like bearing formed at the upper end of an actuating link 50. As shown in F i s 3 and 4 the upper end portion of the lin'i broadens out into a plate-like .part 51 which is about half as thick as the body of the link. A pair of separable plates 53,

-which taken together correspond in shape with the part 51, are arranged. face to face with said part 51 at the front side of the latter. The parts 51 and 53, it will be understood, are each formed with a bearing 0 ening conforming in shape to the part 0 the ball-like memberv49 which is received in said bearing opening, and said part 51 and the plates 53 are adapted to be secured together in any suitable manner as by screws 54 after the ball-part 49 has been arranged between them. The construction is such that a ball and socketor universal joint is provided between the operating lever 46 and the actuating link 50. It will be understodd that after the securing devices 54 are in place the lever 46 and link 50 cannot he accidentally separated at the joint, but that relative movement between the link and lever in any direction is provided for. The lower end of the link 50 is pivotally connected at 55 (Fig. 1) with the arm 22 of the universal bar frame.

7 It will be noted that the ofi-set 47 and extension 48 at'the forward end of the operating lever 46 are in the nature of a' crankarm and handle. I so mount the operating member or lever 46 that it is capable of double or compound movement. It has :1 vibratory movement about a fulcrum or pivot semen locared between its ends nnder the influence or?

Fixed on the operating lever is a ratchet wheel which cooperates with a pawl the pivot whereof is adapted lo remain fixed, ibe result of the coiiperafion between said ratchet and pawl being to effecta step-bystep turning movement of the operating lever on its longitudinal axis for the purpose above referred to, efiecting a progressive crosswise feed of the ribbon.

Referring more in detail to the automatic crosswise feeding devices, 56 designates lugs depending from the top plate and one arranged at each side of the operating lever. The lugs are provided with inclined bearing slots 57, the mouths of which are at the rear and near rho lower end portions of saidlugs, said slots receiving studs or pivot pins 53 extending laterally from the lower end portions of the side arms 59' of a rocking frame, the latter also comprising a cross arm 60 and bearing arms 61 extending downwardly from the middle of said cross arm at the frontand rear sides thereof. The rocking frame is best shown in Figs. 3, 4 and 5. Preferably it is formed of a single piece which is punched out and benf to the desired shape. l The bearing arms 61 are provided near their lower ends with bearing openings through which the operating lever 46 passes and in which it is adapted to bear. Collars 62 are arranged on the operating lever. abutting the outer faces of the bearing arms 61 and are secured in place by set screws 63. The construction is such that the operating lever is support efi two poinfs or places spaced apart lengthwise of said operating lever, these places or hearing points being in the onus 61 of be rocking frame or support The rocking frame is adapted to vibrate on the studs 58 and is prevented rrom any movement toward one side or the other of the machine by the lugs 56 ageinsf which the arms 59 are adapted to abut, although normally' said arms may turn freely between said lugs 56. The; construction is such that when the actuating link 50 is operated an impulse is communicated through the operating lever 46' to the rocking frame, causing the latfier to rock on its pivots and swinging the forward end of the operating lever 46 upwardly, the studs 58 serving in elfect as the fulcrum of said operating lever. it on same time that the forward end of the operatin lever is swung u wardly said lever is caused fir turn slightly on its longitudinal axis, the means comprising a ratchet wheel 64 wbicb is arranged on the operating lever midway Between the bearing arms 61 and js' secured in a fined relation with said lever in any suitable manner as by a key 65 (Fig. 5). Preferably the ratchet wheel is arranged with; respect to the axis of rotaties of the rocking flame, so that the median &

plane of said ratchet wheel, or the plane that passes centrally through it'perpendicularly to its own axis of rotation, contains the axis of rotation of the rocking frame. This arrangement will be understood from a consideration of Fig. 4. Mounted on the operating lever at each side of theratchet wheel 64 are supporting arms 66, said arms being provided with hub portions 67 which sur round the operating lever and bear loosely on it, said hubs being confined between. the ratchet wheel 64 and the bearing arms 61 of the rocking frame. At their outer ends the supporting arms 66 carry a pivot pin 68 of a pawl 69, said pawl being pivoted between the supporting-arms 66 on. the pin 68 and inclining upwardly and inwardly therefrom, terminating in a tooth which cotiperates with the teeth of'the ratchet wheel 64. A flat spring 71, suitably secured at one end to the under side of the cross arm 60, cotiperates with the outer face of the pawl 69 to maintain the tooth 70 thereof in engagement with the ratchet wheel 64. -A spring defeat 72 is secured by a screw 73 to the inner'face of one of the arms 59 and is adapted to cooperate at its free end with the teeth of the ratchet wheel 64 to maintain said ratchet wheel in any of the positions'to which it may be turned or set. which the pawl 69 turns projects rearwardly beyond the rear face of the rear supporting arm 66, as clearly shown in Figs. 4 and 5. and may lightly contact with the inner end portion of a slide rod 74 which is partly supported in thebearing ear 75 projecting rearwardly from the left-hand lug 56 just below the mouth of the slot 57 therein. As

clearlyshown in F ig. 4 the slide rod 74 islocated at some distance away from and rearwardly of the axis of rotation of the rocking frame. Normally the under side of the rear supporting arm 66 is adapted to bear on and be supported by the upturned face of a stop pin 76 which is fixed to the lower end portion of the right-hand side arm 59 of the rocking frame and projects inwardly toward the operatinglever as shown clearly in Figs. 3 and 5. flat spring 77 is suitably secured at one end to the under side of the cross arm or bar 60,, the free end of'said spring codperating with the top of the forward supporting arm 66 and tending to maintain the rear supporting arm 66 in contact with the stop pin or member'7 6.

Except for the slide rod 74 all of the parts thus far described for turning the operating lever on its longitudinal axis (including the ratchet wheel 64, the pawl 69 and the arms 66 supporting said pawl and carrying its pivot pin) are supported on the rocking frame. It will be apparent, therefore, that when the rocking frame and operating lever arev vibrated, vibratory motion about the pivotal axis of the rocking frame will be The pivot pin 68 on tuating 1ink 5O is pulled downwardly, turn ing the rockin frame on its studs and rotating the operating lever 46 about the pivotal axis of said rocking frame as a center, the projecting rear end portion of the pivot pin 68 will be forced downwardly against the inner end portion of the slide rod 74, and will beheld by said slide rod from moving or rocking with the rest of the parts carrie by the rocking frame, said slide rodact-ing as a fixed stop. The outer end portions of the supporting arms 66'will be held up by the co-action between the slide rod 74 and the pivot pin 68 which said arms carry, but the inner or hub portions 67 of said arms 66 will be carried or swung downwardly by the operating lever 46 on which said hubs are loosely supported. The construction is such that a relative turning movement of the arms 66 about the longitudinal axis of the operating lever 46 will be effected, the. hubs 67 turnin on said lever as they are swung downwardly with its rear arm about the center of rotation of the rocking frame and separating from the stop pin 76. The relative turning movement of the supporting arms 66 is transmitted to the pawl 69 carried by them and as the tooth 70 of said pawl is in spring-pressed engagement with the teeth of the ratchet wheel 64 a slight movement of rotation will be also transmitted to said ratchet wheel, causing it to turn slightly about its own axis, the latter being coincident with the longitudinal axis of the operating lever 46. As the ratchet wheel 64 is fixed to said lever 46 the slight axial turning movement of said ratchet Wheel will be transmitted to said 0 erating lever, causing the latter toturn slightly with the result that the extension 48 which has a circular path about the longitudinal axis of saidlever is caused to. travel slightly along its path and to change slightly the position of the ribbon vibrator 44, this change being distinct from the impulse or throw communicated to it through the lever 46 turning on its fulcrum 58.

From what has been said it will be understood that at each downward actuation of the link 50 a double or compound movement is transmitted both to the ratchet wheel 64 and operating lever 46, one part of this movement being the movement of rotation about the axis of rotation of-tho rocking frame, while the other part of the movement is a movement of rotation of the ratchet Wheel and lever about their own coincident axes as a center. Itwillfurther be understood that the amount or extent of turning movement of the ratchet wheel about its own axisand the consequent extent of rotation of the'operating lever 46 will depend '50 will cause the turning of said ratchet wheel through a distance corresponding to one of said teeth or one thirty-second of the c1rcumference of a circle. It will be apparent that the corresponding extent of movement communicated to the ribbon carrier 40 will depend upon the distance of the extension 48 from the longitudinal axis of the operating lever; or, in other words, upon the length of the off-set or crank arm 47. The length of this crank arm may be varied if desired to vary the form or outline of the serpentine path which the type impressions will follow on theribbon. During the return movements back to normal position of the vibratory ribbon carrier and the actuating mechanism therefor, under the influence of gravity and the usual restoring springs, it will .be understood that a return rotary movement of the supporting arms 66 on the operating lever 46 will take place and that the pawl tooth 70 will ride backwardly over the top of the tooth on which it has been lying and will drop down on to the top'of the longer face of the next tooth behind and in position to cooperate with the short working face of the toothover which it has just ridden. In other words, it will be positioned relatively to the ratchet wheel as illustrated in Fig. 5, but will be engaged with the tooth behind (or at the left as viewed in Fig. '5) the tooth with which it is shown engaged in said Fig. 5.

The operation above outlined will -be repeated with each actuation of the link 50 as long as the parts are arranged as shown in Fig. 5 and as a result thereof the extension d8 will turn progressively to the different points in its circular path. Durin this turning movement of the extension 48 it will move from side to side of the slot 45 in the stem 44 of the vibratory carrier and will control the normal position of said carrier so that said normal position will be progressivelyvaried. The lowermost position from which said ribbon carrier may be'lifted is that illustrated in Fig. 4 in the full lines, said position being determined by the lowermost point which the extension 48 reaches during its downward swing. The uppermost normal position of the ribbon carrier is illustrated in dotted lines in Fig. 4 and will be determined by the uppermost position which the extension 48 reaches in its swing or rotary movement. Between-these two extreme positions the ribbon carrier will be moved step-by-step to occupy other normal posi tions, the number of said positions depend; ing on the number of teeth in the ratchet wheel 64. It will further be understood that although the normal position of the ribbon carrier will be varied, yet the extent of movement or throw communicated thereto by the operating lever 46,will at all times be the same since neither the fulcrum of said lever nor the length of the lever arms is ever changed.

My present improvements as thus far described aiford novel means for combining with the lengthwise feed of the ribbon an automatic crosswise feed, and for thoroughly exhausting the entire surface of the ribbon. A ribbon which is intended to be fed both lengthwise and crosswise automatically is commonly uniform in character throughout, although, of course, some times a polychrome ribbon may be employed with such mechanism to obtain variegated or fancy printing. Usually, however, if a poly-.

chrome ribbon like that illustrated in the drawings is to be used it is desirable to write either entirely on one field or on the other field at will. To provide for so using the polychrome ribbon I employ means for dispensing at will with the automatic crosswise feed of the ribbon and for adjusting or setting the vibrator by hand in one of a plurality of predetermined normal positions so that under the unvarying and constant throw of the vibrator one or another of the ribbon fields will be brought opposite the printing point at will. In order to dispense with the automatic crosswise feed of the ribbon I arrange to shift the stop device or slide rod 74iout of the position in which it cotiperates with the pawl carrying mechanism, so that the feeding movement of the pawl 69 may be dispensed with. Any suitable hand shifting mechanism may be employed for this purpose such as the mechanism shown in Figs. 1, 5 and 6 of the drawings. lhe outer end of the slide rod 74 is pivotally connected at 78 with a crank arm 79 fixed to and extending upwardly from a rock shaft 80. The rock shaft is arranged horizontally beneath the top plate, said rock shaft extending fore and aft of the machine and being supported in bearing lugs 81 depending from said top plate. The forward end portion of the rock shaft projects handle 84 is swung rightward, causing the lug or tooth to disengage from the hole 86 and to engage with the hole 87. thereby rocking the rock shaft 80 and sliding the slide rod 74 longitudinally outward in its bearing 75 until said slide rod has been drawn outwardly from under the pivot pin 68. The pivot pin and the supporting arms 66 and pawl 69 will be prevented from dropping downwardly under the influence of gravity after the withdrawal of the slide rod 74 by the stop 76 on the rocking frame. After the slide rod 74 has been withdrawn. as just described, it will be apparent that when the link 50 is actuated, vibrating the rocking frame, all the parts carried by said rocking frame. including the supporting arms 66, the pivot pin 68, the ratchet wheel 64 and the pawl 69, will be rocked with said rocking frame without affecting the relations among said parts. Consequently at the end of the downward pull of the link 50 all the parts carried by the rocking frame will be in the same relations that they were in at the beginning of the actuation of the link and no turning movement of the operating lever 46 about its longitudinal axis will take place, said operating lever merely turningaboutits fulcrum to raise the vibratory ribbon carrier. If it is desired to write on the upper field a of the ribbon the operator after sliding the slide rod 74C out of operative position, as described, takes hold of the extension 48 of the operating lever and turns it downwardly by hand until it has reached the full line position shown in Fig. 4, thereby lowering the ribbon carrier to its lowermost normal position.- With the parts so arranged, if the printing keys be operated the vibrator will be raised upwardly only far enough to bring the upper field of the ribbon opposite the printing point. Ihe throw of the vibrator 1s always the same and as at this time there is nothing to vary the normal position of said vibrator it will always return to the same normal position. Consequently the widthwise portion of the ribbon which is brought opposite the printing point will not vary and the type impressions will follow a straight path longitudinal of the upper field 0:.

\Vhen it is desired to make use of the lower field I) of the ribbon, the operator swings the extension 48 upwardly by hand until it has reached the dotted line position shown in Fig. 4, thereby raising the vibrator to its uppermost normal position and causing it when actuated to bring the lower field b of the ribbon opposite the printing point. It will be understood that the type impressions Wlll follow a straight path longitudinal of the lower field b as long as the parts are related when in normal position as last described. The spring detent- 72 exerts sufiicient friction on the ratchet wheel 64: to maintain the operating lever in either 0f-the positions in which it may be setby hand.

\Vhen it is desired to again make use of the automatic crosswise feed, the adjusting mechanism for the slide rod 74 is shifted back to the first described position, restoring the slide rod to the position shown in the drawings. The end of the slide rod may be pointed as at 74- to insure its passing readily under the pin 68.

Various changes may be made without departing from the spirit and scope of my invention.
