A. SNIB', OF ILION, NEW YORK, ASSIGNOR TO REMINGTON TYPEWRITER A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

7 '0 all whom it m'ay concern Be it known that I, Gnome A. Sam, 9. citizen of the United States, and resident of Ilion, in the county ofy'Herkimer and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a speci-- fication. I

My present invention {relates primarily to ribbon =mechanism for typewriting machines and its general object is to provide new and improvedmechanism of the character specified. 1

:".1 its present embodiment provides a sup rt for the line gage and for the lever or device which actuates the ribbon vibrator said support being mounted '7 lengthwise beneath the platen. The platen independently of but shiftab le 'with the case shifting mechanism of the ma ine through a yieldingconnection between the two and being arrested at the end of t e shift by a stop on the shifted element with which stop the support-is constantly engaged.

" 'The purpose of the construction is to insure a ,practically unvarying extent of shift ing movement for the ribbon vibrator and 'for the line gage notwithstandin'gpossible variation, due to yielding case'shifting parts. I v More specifically theconstruction is designed as an improvement on that disclosed in the application of John H. 'Barr, Serial No. 3,474, filed January 21,;11915, which has eventuated in Patent No. 1 ,153,668,'granted September 14, 1915.

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

In the accompanying drawings illustrating the preferred form of my present invention, Figure 1 is a side elevation, partly in section, of a Remington typewriting machine embodyipg my invention, parts of the machine being omitted.

' trolling mechanism. Fig. 6 is a view cor-" responding to Fig. 4 but shbwing the part in shifted or upper case position. Fig. 7 is a face view of the ribbon vibrator and its guide. Fig. 8 is a perspective view of the vibrator actuators and the associate rocking frame.

' Referring to Figs. 1, 2 and 3 the; main frame of the machine is shown as'c'omprisinga base 1, posts 2 and a top plate 3 that .supports fixed guide rails 4 on which runs a carriage truck 5. A platen 6 is'mounted in a platen frame shiftably connected with the truck, the relatively movable truck and frame together constituting a platen carriage. The platen frame comprises end. bars and a connecting cross bar 8 that extends axle 6 bears in the end bars 7 and these end bars are pivotally connected by devices 9 with the truck 5. A roller1O journaled on the cross bar is adapted to run on aishift rail 11 that is supported by upright arms 12- a y the sides of the base. Collars 17 fixed to said rod outside the levers 15 by set screws 18 preventthe levers from endwise displacement on said rod. Secured to the forward arms of the levers as by rivets 19 are the parallel vertical end portions of a U-shaped ail plate '20, the levers and bail thus providing a rigid frame which bears loosely on the'rod 16 and is maintained in place by the collars 17 Pivoted at 21 on the sides of the bail 20 are forwardly extending arms 22, eachprovided with a shift key 23. Underlying and cooperative with the rear portions of the arms 22 arethe free upwardly and outwardly curving ends of a leaf spring 24 that is secured to the horizontal portion of the bail. 20. The construction provides a ,yielding connection between the" shift keys 23 and the levers15 that support the shift rail. The upward movement of the shift rail is limited by the usual stops 25 on the ends of the carriage truck, said stops acting through the carriage axle 6 to arrest'the shifted parts. Iniaddition stops are provided for positively arresting the arms 22,

said stops being in the form of adjustable screws 26 that are secured in-a stationary cross bar 27, said screws projecting upward into the path of ,the arms 22. Counter-balancing springs'28 are connected at their front ends to lateral pins 20 projecting outward from the upright ends (ifthebail 20, the rear ends of said springs having fixed anchorages 30. The left-hand shifting arm or lever 22 is.providcd with the usual locking devices for retaining t platen in its a uppermost or shifted positio Said devices comprise a sprmg pressed arm 31 pivoted on the left-hand arm 22 and provided \\'ltl1 ll key cap or button 3:2, the lower end of said arm terminating in a hook 33 which is adapted to engage with a fixed abutment 34 to .rock the shift frame down when the'key 32 is actuated. Printing key levers are provided with keys 36 and are connected by links 37 with sub-levers 38, said sulnlevers in turn being connected by links 39 with front-strike type bars 40 mounted on hangers-ll secured to a stationary segment or support 42. A universal bar 43 underlies the key levers and is carried by arms H depending from crank arms 4'5 which project rearward from the transverse rockshaft 46 having stationary end pivots. Projecting rearward frbm said rock shaft near its anddle is an arni 47 which is connected by-a link 48 with certain of the escapementdevices not hereinshown but which are'of ordinary Remington construction.

Ribbon spools 49 are supported one at each side of the machine below the top plate on horizontal shafts 50 and a ribbon 51 is wound on said spools and led upward therefrom through openings in the top: plate, thence inward over stationary gnidesfizz and throughguide openings inthe head or upper portions of a ribbon carrier or vibrator comprising a pair ofparallel wire guide loops rising from aslotted body portion- 54, said vibrator being arranged .about centrally between said stationary nation to feed the ribbon guides52. For turnin the spools in alterongitndinally back and forth, means are provided which' operate on the shafts 50. Said means comprise (as m the'Remmgton No. 10) beveled pinions 55 mounted on the rear ends 'of said a shafts and adapted to mesh with beveled drivingpinions 56 spaced apart ona ribriii'ge is drawn leftward under -.the pull of the spring drum; the driving shaft 57v will be turned, causing one or the other of the ribbon spools to turn and wind the ribbon thereon, thus feeding the ribbon lon 'tudinally. Means preferably of the usua Rembon driving shaft 57 which is connectedthrough constantly engaged beveled pinions -58 and 59 with a spring dram 60, saiddrum being connected by. a strap 61 with anarm ()2- on the carriage truck 5. When the car'- mgton construction are provided for moving the driving shaft 57 back and forth endwise to cause the driving pinions 56 to cn gage alternately with the pinions 55, thus reversingthe direction of the ribbon feed.

The lower end of the ribbon vibrator 53;

54 is pivotally connected at 63 to the hori-- zontally disposed arm 64 of a bell crank lever (55 which, as appears clearly from Figs.

1,2, 4 and 5, further comprises an angularly disposed arm lib-and a brace (37. The arm the operating lever butmcans are provided for rendering them separately etfective at will to operate sald levers said means comprising a rocking frame 75 pivoted onthe rod 70. the rocking' frame having a slotted head 7(tthrough which the actuators 71 and 7:2"pass the downwaxally evtending arms of said frame being cbnneCtedby a cross-rod -77. it spool 78 lodae on the rod 77 is engaged bythe slotted up r end of an angular. plate 7!) which is ml nstably mounted on I the arm 47 by mcans-of two screws 80 and S1.

The

construction is such that v *key's areoperated theframe 75 is melted or vibrated and a motion is' translnittd there from to onefor the other. of the actuators 71 and 72 through the allotted head' 76, the

when the frame 75 isrocked will be trans-- render the actuator 71 operative the frame 75' is slid-toward the left until said actuator is in the throat 76 and the actuator 72 is positioned for idle movement in the opening or slot portion 76. For mimeographing urposes the frame 7 5 is also capable of adustment leftward to bring both actuators in the opening 76", thereby rendering the frame inoperativeon the actuators when the type keys are'actuated. The slidable adjustments of the rocking frame and its cooperation with the actuators are explained more fully in the Barr patent aforesaid.

The endw'ise shift of the frame 75 is accoma crank arm 87 fixed to a rock shaft 88 having stationary bearings and provided with a finger piece 89 which maybe turned to adjust the frame 75. A pointer 90 on the rock shaft 88 cooperates with stationary indicating marks 91 to facilitate; these adjustments. Detent devices forqmaintaining-the frame 75 [set-in adjusted positions comprise a spring plate .92, fixed .to the shaft 88- and having perforations 93 which cooperate with a stationary lug 94. The above described devices for variably actuating the operating lever 65 presubs'tantially likethose described and a5 .clalmedin the Barr atent aforesaid except thatthejadjustable p ate 79 and its associate 'partsreplace a plain arm or plate found in the Barr constr ction;

' Referring-to e novel means for mount- 4 0, ing andfshifting, the ribbonoperating lever 65- to;;w'hichmeans my present invention 'morerespee lly, relates, it will-be seen from FigS; j1,--2;\ and 5 that the pivotrod 68 of the'leve: 65 is mounted on a bail-like frame 95,:this frame constituting a support-for Said frame'95 comprises a cross portion 96 connecting two parallel, rearwardlyextending side portions 97 from which extend 5 downward parallel extensions 98 while on the cross-portiohs extend inclined upward and forward two arms 99 connected by a cross portion 100 having a downwardly pro- I jecting central ear 101, said cross portion terminating at its ends in forwardly pro jecting lugs 102. The ear 101 carries a guide screw 10.3 which'cooperates with a slot in the body gortion 54-0f the vibrator, as best shown in ig. 7. The frame 95' is mounted connected with the downward extensions 98 and in turn are pivoted on'the stationary support. The upper pair of links 104 are 6'5 pivotally connected at 105 and at their rear plished by devices (Figs. land 2) comprising a link 86 which connects said frame with onsets of parallel links which are pivotally ends. to pivot pins 106 on the side portions of abracket 107 shaped like an inverted U, which bracket is secured by screws 108 to the under side of the top plate. The lower links 109 are pivotally connected at their forward ends by laterally projecting pivot pins 110.with the lower ends of the extensions 98 while the rear end portions of said links are pivoted at 111 to the sides of the bracket 107. Back of thepivots 111 the links 109 are connected by an integral cross portion or bar 112, the links 109 and the cross bar 112 constituting a-rigid bail which has the effect .of synchronizing the movements of the links. Diagonal draw springs 113, one at each .side, are hooked at their ends into grooves on the pins 106 and 110; The tendencyiof the springs is constantly to lift or raise the supporting fra,n1e 95 and the operating lever mounted thereon. A stud 114 extends rearward from the cross bar 96 of the frame providing a bearing for a hardened roller 115 This roller is maintained by the springs 113 in constant contact with the horizontal lip or stop surface 116 of a stop bar 117 that extends longitudinally of the frame bar 8 in rear thereof. The stop bar 117 is formed at its ends with vertical slots 118 which receive screws 119 by which the bar 117 isfixed at its ends to the platen frame. The SCIGWutLIld slot connection affords an up and down adjustment of the stop bar 117 and a variable setting of the stop or lip 116 in respect to the platen frame. By securing the stop bar only at its ends to the platen frame bar 8 any distortion or variation in the frame bar 8 due to stresses and strains to which it may be subjected has practically no effect on thestop bar and its lip 116, the bottom face of the lip, atall times remaining substantially in in the same normalrelationship with the platen in both case positions thereof, the

vibrator automatically following the shifting movements of the platen. It will be understood that in shifting from lower to upper case the support 95 moves upward bodily, carrying with it the operatin lever and vibrator-but that the actuators 71 and 72 will not be affected by the shifting movement. During said movement the links 73 and 74 swing upward about-their respective points of connection with said actuators 71 and 72 as pivots. The shifted position of the,parts isishown in Fig. 6.

It will be observed thatthe: link motion by which the up and down movement of the support 95 is controlled embddies at each end of said support what maybe described. as adouble toggle, ne toggle comprising the link 161 and the extension 98 and the .other toggle comprising the link 109 and the downwardly extending arm of the bracket 107. \Vhen in lower case )osition the to"- D When the platen is shifted, the-members .port for the line gage.

com prising each toggle approach nearer each other and consequently require less of a pull from the spring so that though the spring weakens as its ends approach nearer together, it nevertheless exerts substantially the sa'mceti'ect on the toggles in upper case as in lower case position. As a consequence of this compensatory arrangement the pres-- sure of the roller 115 on the lip 11(3 i s'maintained substantially uniform at all times.

The points of connection ofthe spring 113 with the toggle or linkage devices may, of course, be varied as found desirable. On releasing the shift key the platen carrier and ci'mnected parts will be restored to lower case position aslu sual and the lip 116 pressing down against the roller 115 will lower ease position the support 95 together with the operating lever and ribbon vibrator.

The lugs 10: of the support 95am c0nfined loosely between parallel fingers 120 which are integral with and extend upward. Tumirward from a plate 121 fixed to the rear of the segment or support 12. These lingers 120 cooperate with the lugs 102 toprerent sidewisc displacement of the frame' 95 during its up and down shifting movements, the fingers serving as guides for the frame. V

In addition to supporting the pivot rod as the. shiftable frame 95 provides a sup'-* of ordinary constructiorv as illustrated in l igs. 2 and 4 where it 1s designated by the reference numeral 122. The gage 1 s fixed to the front of the cross bar '96 by screws 123, a ,washer plate 124 being interposed between the heads of the screws and the lower portion of the line gage 122. By reason of its mounting on the shiftable support 95 the line gage is maintained in proper relationship with the printing face of the platen in both lower and upper case, the upper edge 122 of the gage proper indi eating or gaging accurately the bottom of the printing line in both case positions. v

1 Besides their guiding function in connection with the frame 95 the fingers 120 serve additionally to prevent the paper fingers carried by the platen from ever getting in the path of the printing typebars. The

paper fingers are of ordinary construction and slidably mounted on a supporting This may be one means consisting that is,

each other-{that the. spring ends to the platen carrier and hav" zontal surface, j'while the on t e sup 125 which extends lengthwise of the platen above the printing line and is sup rted at its ends from the end bars 7. here are two paper fingers 126 of ordinary con-" struction, each slidablyimounted on the rod 125 and extending upwardin front of the platen )ast the printing line thereon, each paper finger carrying at its top a roll 127 and having an outwardl which is provided with a {y ing' lip 128. The path of this lip is intercepted by the fingers 120 so that if the endwise morement of the carriage is continued far enough the lip 127 will contact with the off-set portion associate finger 120 and arrest the paper' finger 126, although the movement of the carriage may continue after such arrest, the

rod 125 sliding through the arrested paper finger. The relationship'between the lip 128 and the inainportion'of the paper finger is such that, as will be understood from Fig.

orwardly extend v 2, the body of the arrested finger will be at one side of the rinting point, indicated at p. It will be 0 rved that by my present invention I provide in combination a platn, types, case shlftmg devices, a rlbbon v1- overcome the springs 113 and'force down to brator, a. support or supporting meansfor the ribbon vibrator, and means constantly tending to shift said support or supporting means; that the said means also provides a.

position of the stop bar and stop roller vary also in a direction at right angles to this first named direction, that is, in an up and down direction, because of the case shifting operation; v

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