To all whom it may concern:

Be it known that I, JACOB FELBEL, citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Vriting Machines, ot which the following is a specification.

My invention relates especially to ribbon mechanisms for typewriting machines andv its object generally stated is to rovide im proved devices oi the class speci ed.

To thc above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts to be hereinafter described and par ticularly pointed out in the claims.

In the drawings, my invention is shown as applied to a front-strike typewriting machine having a shifting platen.

Said invention comprises in the present instance a ribbon guide which normally maintains the printing portion of the ribbon opposite to or covering the printing oint on the platen, said guide being shi'table with said platen and being movable by key operated means to withdraw the printing portion of the ribbon from the platen and expose the printing point thereon. Means are also provided for automatically and progressively moving the guide back and forth transverse] of the platen so as to give a crosswisc eed to the ribbon, this crosswise feed cooperating with the longitudinal feed communicated to the ribbon so as to cause the types to follow a serpentine or wavy path extending lengthwise of the ribbon and substantially from one edge to the other thereof. Other means are provided to dispense at will with the crosswise feeding mechanism and to maintain the ribbon guide set` in one or another of a plurality of predetermined relations with the printinglr point on the platen so that a ribbon maybe used in one or another ot a plurality of straight parallel paths extending longitudinally of said ribbon. The n'leans lastreierred to is especially adapted for use with a ribbon having a plurality of iields or stripes Vof different characteristics, such for example asv different colors. In connection with these general features ot'` tbe invention l have develped various special devices which will hereinafter be described in detail.

Various features of the invention may be adapted in whole or in part to styles of writing machines other than that shown.

In the drawings, Fi ure 1 is a vertical front to rear sectional view of a typewriting machine embodying my invention, said section being taken about centrally of the ma.- chie, various parts of the machine being omitted and broken away. Fig. 2 is a. front elevation partly in section of the machine, parts Iof Said machine being omitted and parts broken away. Fig. 3 is a diagrammatie Vside view showin the mechanism for moving the ribbon gu de away from the rinting point on the platen, said guide being shown withdrawn therefrom.

tndinally. Fig. 11`is a front view, partly in?.4

vertical section, illustrating details of cote` struction of certain `of the ribbon control-yi lnlg devices. I eferrin frame of t le machine 1s shown as comprising a base 1,'corner osts 2 and a top plate 3. Key levers 4- are fn .crumed at 5 at the rear of the'base, cach key lever being provided with a restoring spring 6 and being connected by devices with a type bar 7 the set of type bars being segmentally arranged on a vertically disposed segmental support 7, said sup ort being suitably secured to the irame o? the machine in a fixed relation therewith. Each type bar is provided with an upper case type 7* Vand a lower case type 7, said types being adapted to cooperate with the front face of a cyiindrical platen 8, Ythe axle 9 whereof is journaled in side bars 10 of a platen frame or carrier which further com rises a cross bar 11 connecting said side ars. .T inks 12 connect the platen First to Figs. 1 and 2, the main i carrier with a platen carriage which latter comprises side or end bars 13 and front and rear bars numbered respectively 14 and 15. The latter bars are grooved to coperate with anti-friction balls 16, said balls also cooperating with grooved front and rear guide rails numbered respectively 17 and 18 and fixed to the frame of the machine above the top plate. The carriage is connected by the usual band or strap with a spring drum 19 diagrammatically shown in Fig. 10 which spring drum constantly urges the carriage leftward across the top plate. The leftward movement of the carriage is controlled by the usual or suitable letter feeding devices (not shown) which are operative by the key levers 4.

During the to and fr0 move-ments of the carriage, platen carrier and platen.,4 a roller 20, suitablymounted on the platen carrier, coperates with a guide rai 21 and thc laten carrier and platen are maintained 1n a predetermined relation with the oarriage. This relation will not be varied dur-Y ing the printing and letter feeding operations except when it is desired to change case, whereupon the platen and platen carrier are shifted or moved upward in the carriage by means operative on the guide rail 21 through o( shift-able frame on which said railis supported. Said vframe comprises side rods 22 at the top of which the rail "214 fixed, said rods being supported at thei''flower ends on a cross bar 23 and being,1r movable up and down through openings in the top plate. The bar 23 is carried by sup rting rods 24 which are pivotally connectedgat 25 With shift levers 26 one at each side of the machine, said levers being mounted on ,a rock shaft 2 and each beingnr provided with a finger button 28. Shift stops 28 and 28h limit the shifting movements of the platen and platen carrier.

Ribbon spools 29, vertically disposed beneath the top plate one at each side of the machine and forward of the platen, carry a ribbon 30. Each ribbon spool is mounted at the front end of a horizontal shaft 31, the

construction bein r such that the rotary ribbon carriers or ri bon spools have nd bodily movement and their axial positions are un.-

varying. Said shaft, as shown in Fig. 10, carries at its rear end a beveled pinion 32 which is adapted to mesh with a beveled driving pinion 33 mounted on a drivinor or powe' shaft 34, the latter beim1r journals on a fixed part of the machine an being adapted to be moved endwise in any suitable man.- ner to cause the driving pinions 33 to mesh alternately with their cooperating pinions 32. The power shaft 34 is connected with the spring drum 19 by a train of devices comprising constantly meshi beveled pinions 35 and 36, the pinion being connected with the spring drum so as to rotate with the latter when it turns to draw the carriage in printingr direction while the pinion 36 is so connected with the shaft that it communicates rotary movement to the latter but permits said shaft to move independently in longitudinal direction, all as common heretofore in the Remington No. (imachine.

The devices above described or other suitable devices may be employed to cause the spools to turn alternately to wind the ribbon thereon and feed it back and forth inA longitudinal direction.

The parts hereinbefore described were not invented by me and are not claimed herein, save in combination with other devices of my own invention. It is not.A therefore deemednecessary to describe the before mentioned parts in any greater detail.

The ribbon passes upward from the spools through openingsin the top plate over fixed curved plates 37 which assist to turn or direct said ribbon inward toward the middle of the machine. Midway between the plates 37 the ribbon is threaded through a ribbon uide which comprises a pair of wires 38 nt to forni slot Ways for thc ribbon and secured by soldering;r or otherwise at the top of the body portion 3901:' said guide. said body portion being;r formed preferably of sheet metal and terminating at the top in a bifurcated or forked portiom the wires 38 being fixed at the tops of thc forks forming the bifurcation.

Referring to Figs. l. and Q it will bc seen that the ribbon guide maintains the printing portion of the ribbon or that portion between the slot ways in said tquide close to and covering` the printing point on the platen said printing point beingr rcpresented hy me lottcddine rectangle 40'. that the ribbon extends dowmvard and forward from said guide at both sides thereof toward the plates 37; and that tho rcuido is so arranged that the left-hand guide wire 38 is nearenthe printing point than the righbliand guide Wire. The construction is such that While the printing portion of the ribbon normally covers the printing point, nevertheless, only comparatively few of the characters are covered or concealed from view by the ribbon guide. From some aspects of the invention, however., the ribbon guide need not. be arranged so that the ribbon normally covers the printing point. The ribbon guide extends'vertically downward from the front face of the platen and is provided with a crimp or rearward bend 41 which is formed with a vertical slot and carries a cross in 42, the latter bein pivotally connected, with the forward end of a horizontally disposed o rating lever 43, the rear end portion o with an inclined slot way 44. -Said operatwhich is formed i extends laterally rightward toward the side rof the machine and bears 1n an arm 60 having a` hub 61 which 1s secured by a set screw 'i .alli printing portion had before the platen 4post 2 and being provided at its outer end ing lever, as shown in Fig. 6, passes through l a vertical slot 45 formed within a slidable block 46 in which the` operating lever is pivoted on a fulcrum pin 47. The fulci'uni block 4G is provided with laterally extending ears 48, two at each side of the operating lever, said ears beingr formed with cylindrical holes 49 which receive vertically disposed standards or guide pins 50 fixed to and rising from a horizontally disposed shelf-like part 5l formed at the rear of the horizontally disposed arm of an angular bracket or support 52, said bracket` having a vertically disposed arm terminating in an enlargement or hub 53 which surroundsand is suitably secured to the cross bar or rod 23 of the platen shift frame by a set screw 53 (Figs. 1 and 2).

As stated the fulcrum block 4G is adapted to rest on `the shelf-like part 51. the. block being provided with a` downwardly extending stem 54 which passes through an opening in the part 51 and at its lower end has `a lateral pin 55, saidpin cooperating with a slot` formed in a substantially horizontally disposed crank arm 56. The crank arm has a hub portion 57 which surrounds and is fixed tothe inner end portion of a rock shaft 58. Said roek shaft is journaled at its inner end near the middle of the machine in a lug,r 59 which is integral with and extends rearward from the vertical arm of the bracket 52. As shown in Fig. .2 the rock shaft 53 62 to the cross rod 23. Fixed to and depending from the right-hand end portion of the rock shaft 58 at right angles to the arin 5G is a crank arm (S3 which is pivot-ally connected at` its free end with a forwardly extending and horizontally disposed slide rod 64, said slide rod passing through an opening formed in the rightdiand front corner with a push button 65.

rlhe 4above described construction` enables the fulcruin block 46 and the operating lever 43 supported thereon to be shifted up and down either automatically b v the platen shifting mechanism or by hand independ-` ently of the platen shifting mechanism. 'hen one of the platen shifting keys 28 is operated to elevate theplaten shift framedhe angled bracket 52, which is fixed to the cross bar 23 of said shift frame, will also be elevated and will carry up with it the faleruui block 46, supported on the shelf 51, and the operating lever and ribbon guide, so that hen the platen is arrested in itssbifted position the ribbon guide Will have been xroved sufficiently to maintain the printing portion' of the ribbon in the saine relation with the printing point on the platen as shifting operation. The lower ease position of the platen shifting frame, platen, fnlerum block. operating lever and ribbon guide is illustrated in Fig. l and the upper case position of these parts is shown in Fig. There is` however, a difference between these two figures besides that due to the shifting of the platen, this difference being due to the crosswise feeding devices presently to be described. DuringV the automatic up and down shifting' movements of the ribbon guide with the platen, the rock shaft 58 will he moved bodilyr up and down. carrying;r with it the parts connected to it including' the rod G4 which will be moved up and down idly, said rod fitting loosely enough in the corner post L to permit of this idle or pivotal movement.

lVhen, for purposes presently to be explained. 4it is desired to shift the ribbon guide independently of the shifting movements of the platen, the finger button G5 may be pushed in` causing` the crank arm 63 'to turn the rock shaft 58 and raise the crank arm 56 and the stem 54, the latter operating to lift the fulcrnm block 4G' from the shelf or support 5l, causing the operating lever 43 and the ribbon guide to be lifted so that the relation of the printinpIr portion of the ribbon with the platen is altered, the shifted position of the parts being illustrated in Fig. el. Any suitable means may be employed to maintain the fulcrum block and the parts carried thereon in their elevated position-away from the shelf 51. The means for this purpose shown in the drawings (Figs. 1 and comprises a spring' detent (S6 secured to the corner post by` a screw (5T and coperative at its free end with a notch (i8 formed in the under side of the slide rod (il as shown in Fig. 4. second notch G9 behind `the firstr notch cooperates with the detent (3G when the parts are in the nonshifted position (Fig. 1.) The inherent tension inthe spring detent 6G is such that the f1 ee end thereof will remain in engagment with one ork the other of the notches 6H and 69 in either the lower or upper case position of the platen. In other words, the hand operated devices for independently raising and lowering the fnlcrnln block, operating lever and ribbon guide mayT be actuated whether the )laten shifting devices are in lower case orl slot 44 and carried by a fork 71 fixed at the upper end of a rod 72, said fork loosely embracing the rear end of the operating lever and the rod extending vertically downward from the fork through a vertical opening in the rear end portion 73 of a slide block, said slide block further comprising a horizontally disposed body port-ion 74. VThe slide block is slidably mounted in a bearing block 75, the body portion 74 being formed at opposite sides with longitudinal grooves or depressions 76 with which engage -inwardly extending' ribs or tongues 77 on the bearing block 75. The latter is preferably integral with a supporting bracket 7 8 which curves downward and forward from the block 75 and is provided with lateral ears 79 through which pass headed screws S0, said screws engaging in holes at the rear of the segmental support 7a and serving to cure the bracket lixedly thereto. By this construction the slide block or member 73-74 is adapted to be slid horizontally back and forth fore and aft of the machine in a fixed path. A leaf spring 81, secured by one of the screws 80 at the rear of the associate ear79, cooperates with the front face of the slide block and tends constantly to press it rearward on its support and to force the actuatingr pin to the rear end of the slot 44 in the operatingr lever. The actuating device or actuator for the lever 43, which actuator comprises the pin 70 and rod 72. is adapted to be slid up and down through the slide block when the platen is shifted; but during crosswise feeding operations the rod 72 and the actuating pin T0 are maintained in fixed relation with the slide block h v means presently to be described except when a shift of the platen occurs. in order that' the actuating pin 7") may move in horizontal lines fore and aft of the machine longitudinally of the opera# ing lever and toward and away from tht fulcruln thereof. said pin traversing the in clined or cam slot way t4 to turn the operating lever on its fulcruln and raise and lower the ribbon guide. To accomplish this` means are provided for moving the slide block Tik-74 forward step by step against the spring 8l and until the forward end of the slot 44 is reached by the actuating pin 70 as shown in Fig. 5, and then for per mitting the compressed spring 8l to return the slide block until the pin 70 reaches the rear end of the slot 44. Said means includes an eccentric controlling membermounted on the driving shaft 34 and com prising a cylindrical portion 82. the face whereof is eccentric to the shaft 44, a cone portion 83 at the left of the portion 82 and a hub portion 84 at the ri ht thereof, said hub portion being provide with a circumferenting groove 85 Aformed in part by a loose collar 84., shown in Fig. 1.1 the.

hub 84 is reduced at its right-hand end portion to provide a bearing for the loose collar or sleeve 84", said loose collar being held iu place on the hub by a nut 84 which screws on the threaded end of the reduced portion of said hub and is received in a depression in the loose collar. The hub 84 receives a screw 86, the point of which engages a groove 87 (Fig. 2) extending longitudinally of the power shaft 34, the construction being such that the eccentric controlling member is adapted to be rotated by said power shaft but may be slid lengthwise of said shaft independently thereof to cause the face 82 to operatively engage with the rear face of the slide block 73-74 or to disengage therefrom. lt will be apparent that when the two faces are operatively engaged and the power shaft is turned, the slide block and the pin 70 carried thereby will be moved progressively back and forth, the extent of such movement depending upon the throw of the eccentric face, said throw in the present instance being such that the movement causes the pin 70 to traverse substantially the full length of the slot 44. The spring 8l moves the block in the opposite direction as the high part of the eccentric recedes. The slot 44 and pin 70 are sondjusted that an up and down movement ot' the ribbon guide across the printing face of the platen will be effected, this movement taking place step by step or progressively and being of such an extent that the types will print on the printing portion of the ribbon in a` path extending substantially from one edge to the other thereof. During the forward movement of the pin 70 it acts against the lower inclined edge of the slot t4 to force the ribbon guide upward while during the rearward movement of the pin it permits the guide to be lowered. by gravity.

As has been stated the crosswise movement ot the ribbon takes place concurrently with the lengthwise feeding movement thereof and consequently the path followed by the types will be a serpentine or wavy one. The extremes of movement of the slide block and the actuating pin TO due to the coperation of the eccentric member and the spring Si are illustrated in Figs. 1 and 5.

In F ig. l that portion of the eccentric disk 82 having the shortest radius may be as sinned to be in engagement with the slide block, the result being that the spring 81 will have moved the latter lto its rearmost position and the actuating pin 70 will be at the rear end of the slot 44. In Fig. 5 the disk 8:2 is in contact at its greatesty radius with the slide block and the actuating pin 70 will be at the forward end of the ,slot 44. Comparing Figs. l and 5 it will be noted that in Fig. .1 the ribbon guide is low ered so that the upper edge portionof the ,ribbon is opposite the printing Quint 4on the .construction is such that when t e platen while in Fig. 5 the ribbon guide is shown elevated so that the lower edge portion ot' the ribbon is opposite the printing point. lt is ti'ue that in Fig. 5 the platen is shown in upper ease position whilein Fig. 1 it is shown in lower ease position; but as has been heretofore explained the shift position of the platen does not alter its relation with the ribbon guide and the printingl portion of the ribbon for the ribbon guide shifts with the platen.

ln order that the relation between the pin T0 and the slot 44 may not be disturbed when the slide block and operating lever are automatically shifted by the platen shifting devices, means are provided for shifting the rod 72 iu the slide block automatically when the platen shift occurs. Saidineans coinprises parallel fingers 88 (Figs. 6 to 9) integral with and extending laterally and horizontally rightward from a collar 89 fixed to the rod TZbelow the fork 71 by a piu 90. Confined between the fingers 88 is a horizontally disposed angular arm 91, said arm beingr pivotally supported at the under side of the shelf 51 hv a screw 92 (Figs. 1 and (i). The arm 91 fits loosely between the fingers 88 so that the latter may move freely lengthwise of said arm and said arm may turn on its pivot between said iin ers. The laten is shifted up and down and the brac; iet 52 is shifted therewith the arm 91 will also be lsition.

shifted ard through the fingers 88 will Shift the rod 72 and pin 70 a corresponding egitent and will maint-ain them in .shifted po- During,r the up and down shifting movements of the rod 72 its relation with the slide'block will be altered but the position of the latter will not be affected. Since the operating lever 43 also participates in the shifting movements of the platen, the relation of the pin 70 and the slot 44 will not be disturbed by such shifting movements. The arm 91 eoiperates with the fingers 88 to guide the rod 72 and the pin 70 during the fore and aft sliding movements of the slide block on which said rod is mounted and to cause said pin 70 to travel in` either one of two eti-aight parallel horizontal paths. one of said paths being followed by the pin in lower case position and the other ii'i upper ease position.

The cross feeding mechanism yabizgre described is usually employed in connection with a ribbon of uniform character throughout and when employed with such a ribbon has the advantage of' thoroughly exhausting: theinled surface thereof. Sometimes there is emplov'ed a ribbon divided longitudinally intri a plurality of fields orstrips of different characteristics, suh for example as'tlie ribbon 30 which has an upperlield a of one ehaiaeteristic or color and a lower field b of another characteristic or color. In such a ease it is usually desired to dispense with or render temporarily inoperative the crosswise feeding mechanism and to employ the .hand positioning' devices operative b'y the finger button 05 to set. the ribbon guide and maintain one field or the other of the ribbon opposite the printing' point.

The means employed in the present rase i'or dispensing with the erosswise feeding de- Vieee eouiprisesua vertical arm 93 forked at its upper end to cooperate with the groove 85 in the eccentric member (Figs. 1 and 2). Said arm has a hub 94 which fits over and is suitably secured to the inner end of a slide rod 95., the latter being supported on the arms of a bracket 90 shaped like a'n inverted T and depending ltrom the lop plate. The slide rod 95 extends laterally toward the right-hand side of the machine and at its outer or right-hand end is provided with a collar 97 from which extends va horizontal pin 98, said pin enga ing in a longitudinal Slot at the upper en of`a crank arm 99. The` crank arm 99 extends downward and terminates in a collar 100 which fits over the rear end of a horizontal rock shaft 101 and is fixed thereto by a pin 102. At its rear the roe'k .shaft 101 is journaled in a bracket or lug 103 fixed to and rising from the righthand side of the trame 1 While the forward end portion of the rock shaft passes through and bears in the right-hand front corner ost Q. 'Fixed to the rock shaft in front of he corner post as by a pin 104 is a rrank arm 105, Said crank arm extending upward and beinev provided with a handle or Finger piece 100. Projecting rearward from the upper end of the crank arm is a pointed locking pin 107 which is adapted to eooperate with two holes or openings 108 in the corner post to lock the crank arm and parts controlled thereby in predetermined positions. When the pin 107 is engaged with the left-hand hole 108 the parts are positioned as shown in Fig. 2 and the cecentricA eontrolling member is operatively en gaged with the slide block 734-74. The crank arm 105 is sufficiently resilient to peririit,tliewithdrawal of the pin 107 from lockingr engagement with the holes V108. this being Vdone by pulling forward on the handle 106.

Y In order to render the erosswise ,feeding devices inoperative the locking pin .107 is Withdrawn from the left-hand hole 10B and the crank arm 105 is moved toward the' 'riglituntil the lookingI pin engages with the.

right-hand hole 108. 'This movement of .the crank arm 105 turns the fork shaft 101 and the crank arm 99, tl'i'latter operating `thfrouuh the pin 98 to slide the rod 95 lon v,fritudinallv toward the right thus oausing the forked arm 93 to slide the .eerentrie controlling member rightward along the power 'shaft 34 until said member reaches the position illustrated in Fig. 9 from which it will be seen that said member is entirely separated from the slide block 73-7/1. When the crosswise feeding devices are thus rendered inoperative, it is desirable to withdraw the actuating pin 7 0 from the control of the shiftable angular arm 91, as will be more clearly understood from what follows. To accomplish this withdrawal the angular arm 91 is provided with a rearward extension 91 formed with a longitudinal slot 91", this slot coperating with a pin 109 fixed to and extending upward from the loose collar portion 84a of the eccentric member. The pin 109 may be shouldered as shown to provide a support for the portion of the arm 91 distant from the pivot thereof. During the up and down platen shifting movements the slotted extension 91a will move up and down over the pin 109 Without affecting the latter. When, however, the eccentricI controlling member is slid to inoperative position along the power shaft 34 the pin 109 will act on the slotted extension 91*L to swing the arm 91 on its pivot 92 toward the right from the position shown in Fig. 7 to that shown in Fi 9, thusdisengaging the arm 91 from the ngers 88 and leaving the rod 72 loose in the slide block, thereby rendering the actuating pin inoperative to oscillate the operating lever 43 on its pivot.

When the eccentric controlling member is withdrawn from operation, the slide block will be pushed to the end of its rearward travel by the spring 81 to the position shown for example in Figs. 1, 6 and 9. To'

prevent overthrow and limit this movement the block may be provided with a limiting or stop lug 110 which coperates with a fixed pin or lug' 111 on the bearing block 75 (Fig. 6). This operation of the spring 81 carries the actuating pin 70 to the rear of the slot 44. If, now, the finger button 65 be pushed in to raise the fulcrum block 46 the latter will in its upward movement lift bodily the operating lever 43 and saidoperating lever will carry with it the ribbon guide pivoted at its front end and the lever actuator at its rear end unt-il said parts are in the positions shown in Fig. 4.

From what has ben said it will be apparent that the operation of the rod 64 to set the ribbon guide in one of the two predetermined relations, determined by the spring detent 66 and the notches 68 and 69, will take place independently of the position of the platen, i. e. whether the platen be in normal position or in shifted position; and that the relation between the ribbon guide and the printing portion of the ribbon with respect to the laten will not be affected by the platen shi t. In other words, whether the platen is in lower case or up er case position, the push button 65 may e operated to set the ribbon guide sq as to present either the up er field a (as in Fig. 1) or the lower fieldpb (as in Fig. 4) of the ribbon at the printing point on the platen and the types may be caused to follow a straight path longitudinal of either field at will.

If preferred, an indicating device may be employed to indicate which of the ribbon fields is at the moment operative. Such an indicating device is shown in Figs. 1, 2 and 4 and comprises an angular lever 112 pivoted at 113 on a lug 114 extending rearward from the right-hand front corner post. The lower arm of the lever 112 extends downward and is forked or bif'urcated to provide arms 115 which loosely embrace the rod 64, said arms 115 being loosely confined between two parallel cross pins 116 passing through the rod 64. The upper arm of the lever 112 inclines forward from the pivot and passes through an opening 117 in the corner post, terminating in a circular enlargement or cover plate 118 which is adapted to cover an indicating surface or disk 119 suitably secured at the front of the corner post. This disk may be marked to correspond with the lower field b of the ribbon. For example, if this lower field is red in color the disk 119 may be colored red. When the crosswise feeding devices are in use orwhen the upper field c of the ribbon is employed` the disk 119 is covered by the plate 118 (Figs. 1 and 2), but when the button 65 is pushed rearward to render the lower field operative, the lever 112 will be turned and the plate or cover 118 Willbe moved forward and downward away from the disk 119, leaving the latter exposed to view (Fig. 4), and thus indicating that the ribbon field with which it corresponds is being employed.

When it is desired to restore the eccentric controlling device to'operative position so,

During the first portion of this inward movement vthe pin 109 will operate on the extension 91'l to swing the arm 91 from the Fig. 8. From a. consideration of the latter figure it will be noted that the arm 91 will have passed into the opening between the fingers 8S before the eccentric member can coperate with the slide block 'T3-74. It will be apparent that this is necessary to prevent said eccentric member in some ofthe positions in which it might VYhappen to be, from acting against the slide block and disturbing the vertical position of the rod 72 and fingers 88, preventing the opening in the ltter from properly registering with the arm 91. The inward or leftward movement of the eecentric member and associate yposition shown in Fig. 9 to that shown in parts is continued until they reach the posi tions shown in Fig. 7.

lt will be understooi'l that in all the operations hereinbe tore described the ribbon guide will maintain the printing portion of the ribbon opposite to and covering the printing;l point on the platen. As has been stated the arrangement is siieh that only one or two ot the characters last printed are covered by the ribbon. Sometimes, however, it is desired to inspect the Character last printed and provision is made for accomplishing this by means which cooperate with that portions of the ribbon guide which extends below the pivot` This lower portion or extension may for convenience be designatedl by the reference character ISW.

Referring specially to Figs. 1. Q. and 8, 120 designates a piroted arm or block provided with a longitudinal slot-way 121 which receives the extension Ehi of the ribbon guide. the tit beingll such that relative movement between the extension and the arm may readily be ett'eeted. 'lhe arm is provided with a reduced cylindrical bearing portion 122. the outer end of which is threaded. said b ariiig portion engaging-in a bearing opening in a crank arm 121i. the two arms being prevented troni sei'iarating by a mit 124 which cooperates with the threaded end portion of the part 122. The crank arni 123 extends upward andis formed with a hub 125 which surrounds and is suitably secured to the inner end ofa xoelt shaft 126 as by a pin 127. The rock shaft extends horizontally righti'ard beneath the top plate and is journaled on lugs 12S depending therefrom. crank arm 129'is fixed to and .extends from the rock shaft 1213 at substantially right angles to the crank arm 123 at the opposite end of said rock shaft. A link 130 depends from the free end of the crank arni 129 and is pivotally connected at its lower end with a key lever 131, said key lever being tulerumed at the fiilerinn 5 and terminating at the keyboard of the machine in a tiiiger button 132. The ribbon guide may be moved up and down as has been explained without f'listurbing the key operated mechanism just described, said guide during such movements sliding freely through the arm or block 120. the hitter turning on its pivot and preventing any binding of the Parts. Various of the relations between the crank arm 120 and the extension 31) are illustrated in Figs. 1. Si. 4 and 5. Then it is desired to withdraw the ribbon guide and ribbon from the fare of the platen the key 132 is fle-- pressed. causing the link 13() to pull down the crank arm 129. rook the rock shaft 12b and swing the crank arm 12'8 rearward as said rock shaft turns., The rearward movement of the, crank arm eai'iieswith it the block or arm 120 pivoted at its lower end and the latter will operate on the extension 39 to swing the ribbon guide on its pivot 42 to the position Shown in Fi". 3. From an inspection ot this tigure it will be noted that the printing portion of the ribbon has been moved t'ar enough `.trom the platen to entirely expose the printing line thereon. When the key 1252 is released a` restoring spring 133 will operate to restore the parts to the positions from vwhich they were moved when said key was depressed.

From the foregoing, it will be observed that iii accordance with myinvention the ribbon guide is so held that a portion of the ribbon normally covers or registers with the printing point; that in the style of machine shown this is true in both the lower or normal and upper case or shifted positions of the platen; that there is a separate key-operated mechanism for moving this ribbon guide away troni the platen so as to expose the last letter printed; that the ribbon guide is arranged to be shit'ted automatically with i the platen; that there is a separate key-ir erated means t'or shifting the ribbon guide independently ot the shifting of the platen, whereby the ribbon may be used in either one ot two longitudinal fields as desired; that there is a mechanism for inovingthe ribbon guide and ribbon erosswise during the operation ot' the type keys and that this mechanism is operative in both the normal and shifted positions of the platen; that means aropi'oi'ii'led for rendering this crosswise feeding mechanism temporarily inoperative in ease it should be desired to utilize the ribbon iii separate longitudinal tields; and that means are provided for indicatingr which field of the ribbon is in use. These are some ot the salient features of the invention; others and minor features have been brought out in the foregoing general description. i

Various changes in the construction herein shown and described may be made Without departing from the spirit of the invention` and of course it will'be understood that A-some of the features thereof may be nsed without others. not only in the type of machines shown but in other types.
