Specification of Letters Patent.

Patented July 16, 1907.

Application filed January 31, 1905. Serial No. 243,485.

To all whom it may concern:

Be it known that I, JACOB Fntnnn, a citizen of the.

United States, and a 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-Writing Machines, of which the following is a specification.

My invention relates to typewriting machines and moreparticularly to the ribbon mechanism of such any desired field of the said ribbon.

Another object is to provide means to dispense at will with the crosswise feed of the ribbon in that class of machines employing a ribbon vibrator and wherein the ribbon has a crosswise and a lengthwise feed. .A further object is to provide means to enable a multi-color ribbon to be employed in the last named class of machines.

Other objects will subsequently appear.

To the above ends the invention consists in the features of construction. arrangements of parts and combinations of deviccs to bc hcrcinaftcr more fully described and particularly pointed out in the appended claims.

In the accompanying d rawings, Figure 1 is a vertical front to rear sectional view, takcn about centrally of ono' form of typcwriting machine embodying my invention. Fig. 2 a fragmentary front elevation show ing the upper portion of thc machine. Fig. 3 is a rear view taken on a plane lcprcscmcd by the line a: in Fig. 1. various parts bcing omit tcd. Fig. 4 is a fragmentary top plan view showing parts of lhc ribbon mechanism.

Fig. 4, but showing various pans in different positions from those in which lhcy appear in said Fig. 4. is a rear elevation partly in scction of the ribbon vibrator and some of its associate pans. Fig. 8 is an enlarged perspectivc vicw oi' lhc ribbon vibrator and the operatinglevers connected lhcrcwllli. Fig. i) is an 'enlargcd fragmentary pcrspr-ctivc view of thc ribbon vibrator.

. l\ly invcntion is shown as cmbodicd in a Monarch lypcwriting machinc. butit is to be understood that. it may be adapted to 01 her forms of writing machines.

Fig. 4'

In the drawings, 1 indicates the base of the machine supporting corner posts 2 which in turn sustain a top plate 3. Key lovers 4, each provided with a key cap 5 and a restoring spring 6, are fulcrumed neartheir rear ends on a fulcrum plate 7. Pivoted at 8 to each key lever is a sub-lever 9 formed at its lower end with a slot 10 which embraces a fixed fulcrum rod'll, the latter passing from side to side of the machine beneath the series of key levers. A connecting link 12 is pivotally connected'at 13 with the upper'end of each sublever, and the forward end of said connecting link is pivoted at 14 to a type bar 15, which latter is one of a pivoted to a segment in any suitable manner. As here shown, each type bar is seated in a radial slot 16 formed in a segmental type bar support 1?. The heel of each type bar is perforated to permit of the passage of a segmental pivot wire 18 contained in a groove cut in the top of the segmental type bar support 17. In-

crum wire, the type bars may be provided with separate hangers and pivots as usual. The type bars are normally supported at their forward ends by a type rest 19 and each bar is provided with a type block 20, the types whereof are adapted to cooperate with a platen 21 when said type bar is suitably actuated.

The platen 21 is mounted in a carriage 22, the latter being guided and supported by anti-friction balls or rolls 23 which are seated in grooved mils 24 on the carriage and in oppositely grooved rails 25 fixedly sccurcd to brackets 25 secured to the top plate of the machine. The carriage 22 is provided with a iced rack 26 which normally meshes with a pinion 27, the latter being operatively connected with an escapelncnt wheel 28. Adapted to cooperate with the cscapcment wheel are fccd dogs '29 which are mounted on the upright. arm 30 of a pivoted dog rockcr 3]., the forwardly extending arm 32 whereof is honnccicd with the upper end of a connecting rod 33, which latter at its lower end is connected with a rearwardly extending arm 34 of a universal bar frame .35 pivoted in the base of the machine at 36 and provided with a restoring spring 37. The frame 35 carries a universal bar 38 which extends from side to side of the machine beneath the spacing levers (not shown) and the series of key levcrs 4 and is adapted to be actuated by said levers when the latter are depressed, as happens during each printing or spacing operation. The carriage 2] is connected by a strap draw ihc carriage to ihclcft so that when the universal bar 38 is actuated ihc escapcmcnt mechanism just described i caused to bc o crutcd in a well-known manncr and thcrcby to permit of letter space movements 1 of the carriage.

segmentally arranged series. The type bars may be stead of this mode of pivotingthe type bars on a flul- 3!) with a spring drum 40 which constantly tends to r Ribbon spools 4-1, arranged above the top plate 3 at ouch side of the machine and forwardly of the platen,

i be copying ribbon and the field 9 record ribbon, for

example. The ribbon 42 may be fed longitudinally from either spool to the other by any suitable means. A ribbon feed mechanism is illustrated in the drawings, which, generally speaking, is similar to that employed in the Monarch typewriting machine and which is ex plained in United States patent to Jacob Felbel and Carl Gabrielson, No. 703,339, dated June 24, 1902. Each ribbon spool 41 is carried by an upright shaft 43' which rotates in a fixed bearing 44 and has secured to its lower end a. small beveledgcar 4 5. The gear 45 meshes with a beveled pinion 46 secured to the forward end of a. horizontal shaft 47, which shaft carries at its rear end a beveled pinion 48 which is adapted to mesh with a. beveled driving pinion 49 mounted on a. driving shaft 50. Rotstry movement is transmitted to the shaft 50 by beveled pinions 51' and 52 the pinion 51 being operatively connected with the driving shaft and thepinion 52 with the spring drum i0. It will be understood that 'bothribbon spools are providedwith similar gee-r tmins which are adapted to be actuated from driving pinions le on the driving shaft 50. As explained in the above cited pntentthe driving shaft 50 is capable oflongitudinal movement, and it is furtlier to be understood that the longitudinal position oi-said shalt determines which driving pinion 49 will be in mesh with its cooperating pinion 48, and which ribbon spool willbe turned to'wind the ribbon thereon.

Midway between the ribbon spools'the ribbon 42 is threaded through'a ribbon vibrator or carrier 53- which is guided and supported in the upright arms 54 of the supporting bracket 55 secured by screws 56- to the top plate of the machine. The lower end of the vibrator or carrier 531 bifurcated and formed with aloop 53 adapted to receive d p in 57 carried by the forward end of an actuator and operating lever 58 pivotedM55) in a lug 60 depending from the top plate. The rear arm of the operating lever 58 is formed with a substantially horizontal curved slot 61 which receives'a pin or stud 62 secured st the top of a vertically arranged link .63.-

The link 63 is provided near its upper end with a dowlrwardly bent arm 64, and at its lower end said. link ispivoted at 65 in a. connecting member (iii-which in turnis pivotslly connected at 67 with the arm 34 of the universsl bar frame. The link 63 is adn'pted to be swung about the pivot 67 in order to cause the stud 62 to move longitudinally of the slot 6] so as to engage the operas ing lever 58 at varying distances from ltfl'fillkflflfll 59' and thereby to vary the .throw of the ribboncarrier' or vibrator 53. As herein illustrated; the means employed to swing' the link 63 in order to vary the throw oi the ribbon comprises essentially an eccentric con trol'ler designated as a.- whole' by then'umera-l 68 which? desired to employ a two color ribbon, the latter may I be substituted either by removing from its spools the one color ribbon and replacing said ribbon with the two color ribbon or by bodily removing both the one color ribbon and its spools from the machine and replacing them by another set of spools carrying a two color ribbon, or otherwise. The eccentric device hitherto employed, is an eccentric with a broad working face and which is fixedly attached to the driving driving shaft 50. The eccentric member 68 is thereby slidztbly connected with the driving shaft 50 and is caused to rotate with said shaft, but may bemoved.

tor. The driving shaft 50 may also be moved longitudinally without affecting the member 68. The longitudinal movement of the eccentric member 68 is controlled by apositioning or switching member or slide which comprises first a vertically disposed arm 76 terminating :it the top in a perforated collar portion 77 and at the lower end in a. fork 78 which partially surrounds thedepression 72 of the member 68, and second, two right-singled arms 79 and 80 which are connected with said arm 76 at opposite sides of the latter and somewhat below the collar portion 77 and extend horizontally and to the right of said arm 76 as viewed from the rear of the machine. The forward arm 7 9 is formed with a shoulder 81 and terminates in an inwardly projecting lug or hook 82. The rear arm 80, which lS-SOIXIBWhfii) shorter .thanthe arm 79, is formed with a shoulder 83 and terminates in an in wardly projecting lug or hook 84. A pull and push rod 85 has its inner end fixedly secured in; the collar portion 77 of the positioning member or slide 75'and ing spring is adapted to engage, said locking spring being secured to the under side of the top plate 3 by a. screw 91. The pull and push rod 85 also has at-bearing in' 9, lug '92 depending from the top plate which lug serves also as one of the bearings of the driving shaft 50. A small spiral spring 93 isattached at one end to the link 63 and at the other end to a pin, 94 depending from the under side of the top plate, and said spring constantly tends to draw the link 63 rearwardly about its pivot 67. A. second link 95' is pivoted at 96- in a. connecting member '97, which :in turn is pivotally connected at 98 with the air-r1134 of the universal bar' frame, the pivotal point 98'- being slightly forward of the pivotal point 67 of the connecting member 66-. The upper end of'the forward link: 95 is provided with o projecting pinorstud 99 which is adapted; to enter a slot 100 formed in the short rear arm of a'second. actuator or operating level" 101,. which like: the actuator-or' operating lever 58 is pivoted'at 59 in the dopending leg 60; The two actuators or opwiting levers 58 and 101 are independent of each other. As best appearsin Figs. 3 and 4, the stud 99 is normally disengaged from the slot 100 and stands slightly away from the operating lever 101, the link 95 maintaining :thestud in this position, the contact of said link with an upstanding lug 97, which is integral with the connecting member 97, preventing further motion of the link rightward about its pivot 96. The'second operating lever 101 is bent so asto form a hook 102 around the lower end of the ribbon vibrator 53 and is'adapted to .engage with shoulders 53 formed in the vibrator. A vertically disposed restoring spring 103 isconnected "at its upper end to a lug 104 projecting rearwardly from the ribbon vibrator and at its lower end said spring is connected to a lug 105 projecting rearwardly from the center portion of the bracket 56.

When positioned as shown in Figs. 1, 3 and 4, the mechanism is adapted to give a variable transverse feed to the ribbon, the stud 62, under the control of theejcc'entric face 69, moving toward and awayfrom i the fulcrum 59 of-the operating lever 58 and thereby wise of the ribbonand extending from side to side 'varying the distance the ribbon vibrator moves upward at each printingoperation. The ribbon is fed longitudinally at the same time so that the impressions of the types make a serpentine or wavy path lengththereof. If the ribbon 42 be substituted for the usual and ordinary ribbon, the variable movement of the ribbon'vibrator-will cause some of the types to strike on the field a of the ribbon 42, others on' the field b of movement of the ribbon vibrator when a two color ribbon is used and this is accomplished by means here g inbefore' described. When the parts are positioned to feed the ribbon variably,,the pull and push rod 85 is inits inward position with the locking spring 90 in engagement with the. notch 87 of said rod, as shown in Fig. 3.

In order to prevent variable throw of the ribbon vibrator the rod 85"is pulled outward or toward the left,.as viewed in said Fig. 3, by means of the finger button 86, until the locking spring 90 engages with the, second notchv or. depression 88. This outward movement of the-rod 85 causes the positioning member attached to the inner end of said rod to move also, and the connection between the fork 78 of said positioning member and the sleeve portion 71 of the eccentric member 68 causes said eccentric member likewise to move to the left (as viewed in Fig. 3) to engagement occurs the spring 93 will pull the link 63 back towards the rear end of the slot 61. The leftward movement above referred to of the positioning member 75'causes the arms 79 and 80 of said member to assume the position shown in Fig.5, wherein, it

I will be noted, the inner face of the lug or hook 82 is incontact 'withthe upper portion of the forward link 95 and the inner face of the lug or hook 84 is in con tact with the upper portion of the rear link 63. When the locking spring is engaged with the second notch 88 of the rod and the parts-connected withsaid rod (that is the positioning member or slide 75 and the eccentric controlling member 08) have assumed the positions above described, the pin 62 of the link 63 will always be maintained at the rear end of the slot 61 in the operating lever 58 by means of the spring 93. The result is that the ribbon vibrator 53 will be operated by saidlever 58 to lift the ribbon at printing operations to a position relative to the printing line which is unvaryiug. The parts are 50 adjusted that this unvarying movement or throw of the ribbon vibrator will always bring the printing field d of the ribbon'42 into position to receive the impressions of the types, and the path of the type impressions will be in a straight line extending longitudinally of the said field a. The vibrator is lifted by the lever 58 by reason of the contact of the pin 57 with the upper end of the loop 53 of the vibrator, and said vibrator.

is restored to normal position by the spring 103. When actuated by the lever 58 the vibrator is lifted away from the lever 101, and the latter remains motionless throughout such actuation. If it be desired to print from the lower field b of the ribbon 42 the rod 85' is I of the lug 84 of the arm 80, and the link is swung the stud 99 has been brought into engagement with the slot 100, thereby connecting the link 95 with the operating lever 10]. The link 95 is secured to the universal bar frame somewhat nearer the center of motion 36 of said frame than is the link (33, and consequently the movement of said link 95 at printing operations, is somewhat less than is the movement of the link 63. The link 95, however, acts upon its associate operating lever 10] so much nearer the fulcrum 59 than the link 63 acts upon its associated lever 58,

when it is connected therewith in the manner illustrated in Fig. 5, that the forward end of the operating lever 101 moves a greaterdistance upward when actuated at printing operations than does the forward end of the operating lever 58 when it is actuated at printing operations. The result is that the ribbon vibrator is lifted to a greater height when actuated by the operating lever 101, and the parts .lre so adjusted in the latter case as to bring thc held I) of the ribbon 42 into printing position at each printing operation. The throw of the lever 101 under the influence of the link 95 does not vary and the path of the type impressions will be in a straight line running longitudinally of the ribbon field b. move upward by the lever 101 by reason of the engagement of the forward bent portion or book 102 of The ribbon vibrator is caused to the actuation of the ribbon vibrator by the link 101.

If it be desired to again position the parts to cause the ribbon to feed crosswise automatically, the rod 85 is pushed inuntil the locking spring 90 engages with the notch 8Z As this is done the tapered or cam portion of the eccentricmember will effect an easy and certain entrance into the space between the link 63 and its bent arm 64 and will thereby insure that the eccentric face 69 will again engage with the strap of the link 63. This return movement of the rod 85 also causes the shoulder 81-of the forwardarm 79-of the positioning member 85 to swing the link 95 back towards the right hand, as viewed in Fig. 3, about the pivot 96, and causes theshoulder 83 of the rear arm 80 to swing the link 63 to the right about its pivot 65. The parts are thereby restored to the positions illustrated in Figs. 3 and 4. i I

Certain broad features herein shown and described are not claimed herein as they form the subject-matter of a separate application, Serial No. 238,588, filed De cember 28, 1904. I

In certain of the appended claims where two actuators are recited as both normally operatively connected with-the ribbon carrier, itis to be understood that by this expression ismeant that either of the said two actuators (which in this case are the operating levers'58 and lollmay normally be actuated to operate the ribbon carrier without thenecessity offirst shifting either .of said twoza' ctuators into operative connection with said ribbon carrier, in contradistinction to the devices shown in my: said application Serial No. 238,588,

wherein, if the actuating links be considered as actuators, one of said links or actuators is normally cut off or disconnected from the'ribbon carrier and cannot be operated to actuate the carrier until after certain switching or shifting devices are operated to operatively. connect the normally inoperative actuator with the carrier.

In certain other of the appended. claims reference is inadeto one of the actuators remaining at rest or unaffected while the other actuator in action or in operation. This is for the purpose of more fully distinguishing from the mechanism, of my said other application Where both of the actuators or links are simultaneously in motion during the operation of the printing keys. Therefore no claim in this case is to be construed carrier operating lever,

so broadly as to cover the construction set forth in my aforesaid application, Serial No. 238,588, wherein my broadest claims appear.

Various changes in the construction and airangement of the parts may be effected without departing from the spirit'and scope of my invention.
