Serial No. 429,996.

' citizen of the United States, and resident of the borough of Brooklyn, city of Yew York, in the county of Kings and State of New York, have invented certain new and useful Improvements in 'lype-V'iting Machines, of which the following is a specification.

My invention relates especially to ribbon mechanism for typewriting machines and its object generally stated 'is to provide improved mechanism of this class.

More specifically, one object of the. invention is to provide automatic cross feeding devices for a ribbon which is controlled by a central ribbon guide which guides the printing portion of the ribbon crosswise of the printing line.

Another object is to provide interchangeable automatic cross feed devices, whereby the extent of cross feed may be varied.

Another object is to provide means for dispensing' with the automatic. cross feeding devices and for enabling the ribbon guide to be set in selected positions whereby the ribhon may he used in predetermined lields extending lengthwise of the. ribbon.

Another object isto provide nrezzns operative automatically to cut out: or render inoperative the longitudinal ribbon feeding mechanism when the carriage is released from its letter fee-ling devices. said automatic means being operative both by the usual release key of the machine. and also by one or more titlltlltltlllg keys.

Other objects will hereinafter appear.

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

My invention is especially adapted-to the. Smith Premier typewriting machine,.which is an under-strike machin and in the pres- -eut instance I have hun-n the invention a pplied to that machine, but the nature of the invention such that various of its features may be applied to other styles of writing machines.

Referring first n-" 'e especially to Figs. 1, 2 and 3, the main fame of the machine is shown as t'tlllipl'ifilllg a base 1. posts 2 and a top frame part or plate 3. A set of type. bars (not shown) are eirt'rularly arranged on the top plate and are connected by the usual train of actuating devices (not shown) with linger keys 4. The type bars, when a tuated. coi'iperate with the under side of a platen .7 having an axle a which is support-2d on the side bars I of a carriage, which carriage further comprises a front bar 8 and a rear bar 9. The front and rear bars are oppositely grooved to cooperate with antigrooved front and rear guide rails numbered respectively 11 and 12, said guide rails beand shaft 16. Said shaft at its rear end carries an escapement wheel 19 having teeth 20 which are adapted to cooperate with a loose dog 21 pivoted on a carrier 22 which in turn is pivoted on a carrier 23 carrying the fixed dog 24. The carrier is secured to the upper end of a vertical rock shaft 25 journaled on the frame of the machine, the lower end of said rock shaft carrying an arm 25 which connects with the usual universal bar or gate (not shown), said gate being operated when each of the printing keys 4 is depressed, so as to cause the escapementdogs 21 and 2st to cooperate with the teeth of the escapement wheel to permit the carriage to be drawn a letter space distance leftward by the carriage power. Said carriage power comprises a wheel 26 connected by a band or strap 27 with the carriage. Integral with the wheel 26 is a hollow drum 28 which contains the usual power spring, said drum being loosely mounted on a drivin shaft 29 which extends fore and aft of the machine and is journaled in the left-hand front and rear posts 2. A ribbon spool 30 is loosely n10unt ed on the driving shaft 29 just back of the front co ner post and is held from movement lengthwise of said shaft but is adapted to be turned in unison therewith by devices comrising ratchet teeth 31 integral with the rear ange of the spool 30 and a sleeve 32 slidably mounted on the shaft 29 and provided with ratchet teeth 33 which are adapted to mesh with the ratchet. teeth 31. The driving or ribbon spool shaft 29 is normally connected with the spring drum 28 by devices comprising a ratchet wheel 34 fixed to the rear end of the shaft 29 and a pawl 35, said pawl being pivoted between its ends to the spring drum 28 at 36. A coiled spring 37 is connected at one end by a screw 38 with one of the s okes of the wheel 26, said spring at its at er end engaging a pin 39 on one arm of the awl 35 and tending constantly to maintain the tooth 40 on the other arm of said pawl in en agement with the teeth of the ratchet whee 34 At the opposite side of the machine a ribbon spool shaft 41 is journaled on the righthand posts 2 and carries adjacent to the rear ost a ribbon spool 42,said spool being mounted so that it may turn independently of the shaft 41, but being held from endwise motion therealong. The spool 42 is adapted to be connected to turn in unison with the shaft the rear face of a sleeve 45, which sleeve may be moved endwise of the shaft 41 but is connected to turn always in unison there with. A crank arm 46 has a hub 46 which is arranged on the rear end of the shaft 41 and is suitably fixed thereto. The shafts 29 and 41 are connected to turn in unison by a rod 47 which is loosely mounted on slctted brackets 48 depending from the top plate, said rod 47 terminating in spherical ends -l9, one of which is detaehably seated in a depression in the ratchet wheel 34; and the other in a depression in the,crank-arm 4G. The usual or suitable reversing mechanism may be employedto move the sleeves 32 and 45 alternately into and out of connection with their associate ribbon spools so as to reverse the direction of longitudinal feed of s the ribbon. By this alternate turning of the spools the ribbon is fed longitudinally back and forth across the printing point. This longitudinal feed of the ribbon is derived from the connection of the spring drum 28 with the driving shaft 29, said connection com risin the ratchet wheel 34 and the paw 35, he pawl being the driver and the ratchet wheel the driven part. The nature of the connection is such that it is operated during the movements of the carriage from right to left across the top plate, but when the carriage is returned or restored in the 01p osite direction the pawl tooth 40 will s ide idly over the teeth of the ratchet wheel 34 without affecting said ratchet wheel or the spool shafts. I

The rear flange of the s 001 30 is somewhat nearer the front of t e machine than thefront flange of the spool 42 and the ribbon- 50 is directed from one of these spools to'the other in an off-set path, being led upward from the spools through suitable slots in the top plate and thence directed inward toward the middle of the machine where it is turned or folded over oblique turning bars 51 carried on a slidable member or guide plate52. The ribbon passes from above the spool 30 over the top plate, under the lefthandportion of the guide 52, up over the front turning bar 51 toward the rear of the machine, over the type opening between the two turning bars, over the rear turning bar, thence down under theright-hand side portion-of the guide 52, over the top plate and down-through the slot therein to the spool 42. The arrangement is such that the printing portion of the ribbon, or that ortionbetween the turning bars and overlying the same, extends transvcrselyor at r ght angles to'the length of the platen and the lines embraces the guide bar 54.

portions of the ribbon between the spools. I

The printing point is indieated by the dotted square 53 in Fig. 3. and from an inspeetion of this figure it will be seen that the printing, pointlies back of the left-hand rib- )Oll spool and in front of the right-hand ribbon spool and that the types will strike 5 5 onee been set in the position for useby adonly the printing portion of the ribbon.

'The guide plate 52 is mounted to slide on i a fuide bar 54 on the top plate at the rear site of the mat-blue,

the guide plate being I provided with a lip 51', so that. it partially The guide plate E 52 at. its front side cooperates with a seeond 5 guide bar on the top plate, said guide plate. at its front side being confined between the guide bar 55 and the under side of the front rail 11. The guide bar is provided with lingers. 52 which extend downward through a slot at It will be understood that the guide plate 52 is adapted to be moved lengthwise of the guide bars to present different widthwise parts of the printing per:

tion of the ribbon to the types. This movement of the guide plate ma y be accomplished by hand as in the Smith Premier machine or automatically as provided for by my present 1 invention.

The parts thus far specifically described are or may be the sam as the corresponding parts of the No. :2 Smith Premier typewriter. and it is therefore not deemed neeessary to describe them in greater detail. .The guide plate 52 has a forwardly extending part 52 on which is pivoted at 57 an angled member or part 58 provided with afinger p1eee 59 and a rem-wardly prtnectmg lug (it). top of the mat-lune frame and a guide bar (31 seem-ed thereto by screws (32. The guide bar .61 is'provided with a lug or having a concave fat-e61 which is adapted to 006p- ,erate with the finger piece. 59 when the guide .is moved leftward to render the ribbon numerative. The front end of the part 58 is beveled to provide a pointer wlneh to operates with an indicating plate (33.

The ribbon mechanism thus Far described -1nay be employed with a ribbon of uniform ehara'eter throughout, but is espeeially adapted for use with a ribbon divided longitudinally into a plurality of tields or stripes of different characteristics; sueh. for

and the field 1' to be t'olored with purple.

t'opying'v ink. When a ribbon likethat just describwl has been heretofore emploved 1n the \o. '2 Smith lrenner marlune, said ribbon has been usually adapted to be written on in a single line lengthwise ot' the field a,

in a single line lengthwise of the field I), and Y in a plurality of parallel lines or paths lengthwise of the broader field (a lo the ease of the fields I! and I. after they have i so on until the entire width of the field has been thus used. 3y my present invention I provide for using a ribbon like 50 in a line or path lengthwise of the field H and in a line or path lengthwise of the field I), the guide 52 being set for either lield and held in set position by the frirtion between the guide and its guide bars .3 1 and When, however, the broader tield 1' is to be employed, I provide means for automat'irally reciprocating the uide 5:! from side to side so that the ribbon is fed erosswise bark and forth from one edge of the field 1' to the other sinmltaneously with the longitudinal feed of said ribbon. the result being that the types will follow a serpentine path extending, lengthwise of the field 1' and enrvin; substantially from one ed' e to the other thereof. 'hen the ribbon at) is replaced by a ribbon of uniform eharaeter througl'iout. its width. my invention enables the extent of the automatie rta-iproratory movements of the guide 5:2 to be inereased so that the ribbon may be fed erosswise to the full ex tent of its width and the serpentine path will wave or eurve substantially from one edge to the other thereof. I

The automatic means for sliding the guide plate 52 to and fro, eomprises an arm (34 (Figs. 1, It, 4 and 5) pivoted at (35 to the guide plate 52 and extending horizontally over the latter toward the right hand side of the mat-lune. leat' springtitt, secured to the guide plate by a screw 6T,'eoiiperates with the arm (it and tends constantly to press it forward. the forward movement of the arm It} being limited by the hip' 30 on the part 55, which in turn is arrested by a lug 52 integral with and extending forward and upward from the glide plate 52. The

right-hand end of the arm Ulis beveled as indieated at (34. and said arm is provided near its free end with a slot (38 whieh is adapted toengagetheupperend of a vertieallydis- 69 is effected, after which the finger piece posed operating arm 69. said operating arm, l as shown in Figs. 1 and 4, extending downl ward through an opening in the to plate l near the right-hand side of the machine and I being pivoted at 70 t0 ,a lug 71 extending l inward from the rightshand side of the base l l 1. This operating arm is adapted to be swung. on its ivot inward toward the mid dle of the mac inc and in the opposite direction by interchangeable devices which receive motion from the right-hand ribbon s ool shaft 41. These devices are most c earlyshown in Figs. 5 and 6 and comprise an eccentric carrier 72 which has a hub 73, the latter receiving a set screw 74 which engages the shaft 41 and secures the eccentric carrier in a fixed relation therewith. At its front side the eccentric carrier has formed integrally with it an eccentric 75, and at its rear side, a smaller eccentric 76. T119313 eccentrics coiiperate with suitable straps numbered respectively 77 and 78. The strap 77 is held in place by a plate 79 which is secured to the carrier 72 by a headed screw 80 and' the strap 78 is similarly held in place by a. plate 81 which is secured to the carrier by screws 82. The. strap 77 is provided with a finger piece 83 and diametrically opposite thereto with an extension 84 formed with a slot 85. The smaller strap 78 is similarly provided with a finger iece 86 and an extension 87 formed wit a slot 88. The slotted strap extensions 84 and 87 are ada ted to cotiperate one at a time with headed studs or pins extending oppositely from the front and rear faces of the operating arm 69 and numbered respectively 89 and 90. In the drawings the slot 88 of the extension 87 is shown engaged with its associate stud 90, thus rendering the strap 78 and the eccentric 76 operative, said strap and said eccentric coiiperating during rotary movements of the shaft 41 to transmit a reciprocatory movement to the operating arm 69 and from it through the arm 64 to the carrier 52. The throw of the eccentric 76 is sutiicient to reciprocate the uide 52 to an extent that will enable the fielt c of the ribbon to be moved automatically back and forthwidthwise of the printing point so that substantially th full width of said field ma y-be employed.

If it be desired to dispense with the automatic cross feed and make use of either of the fields a or b, the arm 64 may be moved rearward on its pivot against the spring 66 until the slot 68 disengages from the upper end of the operatin arm 69. This rearward movement of t ie arm 64 may be accomplished by pressing rearward on the finger piece 59, causing the lug 60 to turn the arm 64 on its pivot against the spring 66 until disconnection from the operating arm 59 may be used to slide the guide plate 52 downward until the s to the proper position for using either the If it be desired to entirely dispense with the use of the ribbon, the guide plate 52 may be moved leftward by hand until the stem of the finger piece 59 is seated in the depression 61". This movement of the guide is sufficient to leave the printin point uncovered so that mimeograph wor may be done or the types may be cleaned, etc.

When it is again desired to connect the guide plate 52 with the operating arm 69 said guide may be slid either toward the right or toward the left to cause the slot 68 to ret ngage-the upper end of said operating arm. It the slot 68 happens to be at the right-of the upper end of the arm 69 the guide 52 is moved leftward so that the front edge of the arm 61% will slide along said operating arm until said arm is en aged by the slot owing to the pressure of t e spring 66. If the free end of the arm 64 is at the left of the upper end of the operating arm 69, the guide 52 is slid rightward by hand until the bevel or cam edge 64 contacts with the upper end of the arm 69, causing the arm 64= to be forced rearward until the slot 68 engages said operating arm.

If a ribbon of uniform character throughout be substituted for the polychrome ribbon 50 and it be desired to feed said uniform ribbon automatically substantially from one edge to the other thereof during the Iongitudinal feeding of said ribbon, tne eccentric strap 78 may be disconnected from the operating arm 69 by pressin the handle 86 0t 88 isengages from the stud 90; and thereafter, by manipulating the handle 83, the slotted extension of the strap 77 may be caused to engage with its associate stud 89 on the operatmg arm. The

throw of the larger eccentric is of an extent to provide for feeding the ribbon crosswise substantially from one edge to the 1 other thereof.

Of course if desired both the eccentric devices may be put out of operation and the guide 52 may be set entirely by hand, as

heretofore.

Where, as in the resent case, the longitudinal ribbon feeding mechanism is connected with and actuated by the. carriage power or spring drum, it has usually happened heretofore that when the carria e is released from its escapement devices either by operathig the usual releasekey, or a tabulator key or otherwise, and is drawn fully or impelled varying distances toward the left, the ribbon will be fed longitudinally corresponding distances. Darin such feeding of the ribbon the printing evic s are inactive and consequentlv a section of the ribbon. corresponding to the distance which the carriage umps or is drawn freely, Wlll pass the printing point without being used; that is, without receiving: impressions y from the. types. As the ink in the ribbon becomes more and 'more extinct in use. these 3 unused sections or patches become more apparent in the printed work, some of the characters being much darker than others, with project the vstops 1071 forward by push rods 101' umlcrlyinglthe base of the machine and (Xtotnltlllf tore-:and aft thereof, said push rods each l)(.;H'Hl-; f near the trout of the mafv chine in a detachable bearing member 107 the result that the wn'tin; has an irregular.

The stops 105 are adapted to cooperate with one or more column stops 110 on a rack bar 111 supported on brackets 112 detachably secured to the carriage. In order to'antoluatically release the carriage when any one of the stop blades lt t operated, a universal bar 112, is arranged transversely behind the stop blades and below the pivots thereof,

overlying the feed rack 13 and pivoted there- I to or studs ill at the ends of said rod. The. i

bar 93 when raised by the release key, as shown in Fig. 12. acts on the upper fork 95 of an arm 96 which arm is pivoted at J? to the upper end of a rock shaft Q8. The lower-fork 99 of the arm 96 underlies an arn r l tl (Figs. 2, 3, l3 and 1-1), which is pivoted at 101 to the frame of the machine and t-.o '3perates with the lever 15 at the opposite side of the shaft 16 from the pinion 14. When the forward end of the release key 91 is depresscdthe nose at the rear end thereof swings the bar 93 up to the positi n shown in Fig. 12, said bar 93 A leaf spring 120, acting against the universal bar 11 tends to maintain the latter in normal position as illustrated in Fig. 1. When one of the linger buttons 108 is pressed in, the corresponding blade 104 is swung on its pivot, projecting the associate denomination stop 105 into the path of the column stops 110, as shown in ig. 7, and

The releasing arm 121 is pivoted at 122 at the top and rear of the machine frame and extends from its drum, being formed with an upwardly bent portion 121 which overlies the fork J5 and is adapted to be operated thereby, (Figs. 1, 2, 7, 12 and 13). The left-hand end portion 121' of the releasing arm normally restson the top plate and the end thereof underlie-s the rearwardly inclined or cam end 123 of an extension 124- which is formed integral with and projects upward from a release ring or annulus 125.

Said annulus is sup- The arm 115 of the releasing frame of the ported on an arm 126 formed'integrally therewith and extending vertically ownward and diametrically opposite to the extension 124. Near its lower end the arm 126 is provided with forwardly projecting cars 127 which receivea pivot pin 128 sa orted on a block or bragket 129, said racket being bifurcated to embrace the left- .10 hand side of the base 1 and being detach ably secured thereto by a screw 130. A leaf spring 131, secured to the block 129 by a screw 132, contacts with thesfront face of constantly to maintain the member camposed of the arm 126, annulus125 and extension 121 in the normal position shown in Fig. 1. A lip 126 integral with the arm 126 and extending below the pivot 128 is adapted to contact with the block 129 to limit the rearward movement of the member under the influence of the spr'n 131. From an inspection of Fig. 1, it will he seen that normally the annulus 125 is in a plane behind a plane containing the rear face of the ratchet wheel 34. As presently tobe described the ammlus-carrymg member is adapted to be swung forward by the operation' of the releasing arni 121 until it partly encircles the ratchet wheel 34, as shown in Fig. 7. During its forward movement the outer face of theannulus engages a pin or stud 133 fixed to and projecting rearward from the pawl below the pivot thereof '(Figs. 1, 2, 3, 7 and 11). As clearly shown in Figs. 3 and 11, the stud 133 is cutaway to provide a cam face 133 which face is actcdon by the annulus in its forward swing -to' force the pawl 35 to turn on its pivot against the pull'of the spring 37 and disengage the pawl tooth 40 from the teeth of the ratchet wheel 34, thereby disconnecting the earria e power from the ribbon mechanism. T e awl 35 and stud 133 beiugon the 5 ring rum revolve. in a circular path, but t e annulus 125 having a corres onding circular face will coiinerate with v t c stud 133 at any point inthe path of revolution of said stud.

As clearly shown in Figs. 12 and 13 the bent: portion 121 of the releasing arm 121 overlies the fork 95 near the root or junction of said fork with the arm 96. When the release key 91 is operated to release the carriage from its step-by-step feeding devices,

the fork 95 in its upward movement will contact with the bent portion of the arm 121 'and will swing said arm upward on its pivot 122, causm the free end of said arm to engage with the cam 123, swin ing the annulus carrying member forwar on its pivot 128 and causing the annulus 125 at some point on its outer face to act against the cam 133 to disconnect the pawl 35 from the ratchet whee1.34.

tabulator is provided above the pivot 103 with 31.1 upwardl and forwardly curving extension 115, tie end of said extension having suitably secured to it a cam late 115 which is adapted to contact with bracket 134 riveted to the part 121" of the releasing arm. When one of the tabulator keys 108 is operated the arm or extension 115' is swung forward, causing the earn 115" to'engage with the lower edge of the, outer end of the bracket 134, lifting the latter and through it swinging the releasing arm 121 upward on its pivot to act on the cam 123, causing the ratchet 125 to disengage the pawl from the ratchet wheel 34, as previously described in connection with the operation of the release key 91.

It will be seen that the release key and the key controlled tabulatin'g mechanism are operative independently of each other to release the carriage and cut out the ribbon. Further it will be noted that said release key and said tabulating mechanism are operalive to release the carriage by breakin the train of carriage feeding devices at di fercnt points, the release key separating the feed rack and feed pinion while the tabulating mechanism separates. the engaged dog from the escapemcntwheel.

Various changes may be made without departing from the spirit and scope of my invention. 1
