HENRY W. MERRITT, OF SYRACUSE, NEW Y ORK, ASSIGN'ORlTO THE MONAROH TYPEWRITER COMPANY, OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed February 10, 1906. Serial No. 245,078.

To all whom. it may concern:

Be it known that I, HENRY W. MERRITT,

citizen of the United States, and'resident of Syracuse, in the county of Onondaga 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 more particularly to 10' the ribbon mechanism of thatclass of typewriting machines. commonly called visible writers and wherein the Writing is visible to the operator'as he writes. In such Ina--- chines it is usual toemploy in connection with the ribbon a ribbon vibrator or carrier, which term, as used herein, means any device for moving the ribbon to and from the printing point under the control of the printing keys.

One object of my invention. is to provide a construction wherein a ribbon having a plu- I rality of fields. of different characteristics 5 may at each printing operation. be moved to cover the printing point with any of its fields, as desired. v

Another object is'to provide means for dispensing at will with the crosswise feed of the ribbon in that el-ass of machines employing aribbon vibrator and wherein the ribbon has both. a crosswise and a lengthwise feed.

Another object 18 to provide means to enable a ribbon of more than one color, com- Y monly called a polychrome ribbon, to be em- Q plo'yecl 1n the last named classof machines.

.hereinafter more fully described and articularly pointed out in the conclu 'ng claims.

I have illustrated my invention as embodied in the Monarch typewriting machine, but I desire it to be understood that it may be adapted to other formsof writing machines. I

In the drawings, lindicates the base of a typewriting machine supporting corner posts 2, which latter sustain a top plate 3.

Key levers 4., each provided with a restoring spring 5, are fulcrumed on a fulcrum plate '6. A sub-lever 7 is pivoted at 8 to each key lever and the lower portion of said sublever is adapted" to cooperate with a fixed abutment9. The upper end of each sublever is connected .by a link 10- with atype bar 11 which is'one of a segmentally war- 1 ranged series, eachtype bar whereof is seated in a radial slot 12 formedin a segmentah type bar support 13. The heel of eaoh'type bar-is perforated to permit .of the a groove in the top of the segmental type bar support. The type bars instead of being pivoted on a fulcrum wire, as herein shown,

may each bepr'ovided with individual hangers andpivots. A type rest 15.normallysupports the type bars at their free [ends and said bars when suitably actuated coiiprate with a platen 16 mounted in a carriage 1.7, said carriage beingguided and suppo tedby anti-friction balls '18 which are seatedein grooved rails 19 .on the carriage and in -op-, positely grooved rails 20 securedtebrackets 21 fixed to the top plate ofthe mach ne The carriage .17 is provided with a feed rack 22' which normally meshes with a "pinion -23, the latter being operativel-y' oonnecteagwithan escapement wheel 24. Feed dogs .25 are 1 1 Patented Oct. 27, 1908.

. Passage of a segmental -p1vot wire 14 contained .lIl.

extending arm 29 of a universal bar frame.

30 pivoted in the base of the machine at 31. The frame 30 carries a universal bar 32 which extends from side to side of the ma chine beneath the series of key levers 4.and the spacing levers (not shown) and-is adapted to be actuated by said levers when the latter are depressed during printing or spac-- ing operations. The carriage 17 is connected by a strap orband 33 with a spring drum 34, which constantly tends to draw the carriage to the left, the result being that when the universal bar 32 is actuated, the escapement mechanism above described is caused to be operated in a known manner and thereby to permit of letter space movements of the carriage. I

A pair of ribbon spools 35, arranged above the top plate and forwardly of the platen, one at each side of the machine, receive a ribbon 36 which, as herein shown, is divided longitudinally into fields a and b of different characteristics; for example, the field d may be of one color as black, and the field b may be of another and different color, as red, or the field a may be copying ribbon and the field Z) record ribbon. The ribbon 36 may be fed lengthwise from either spool to the other by any suitable means. The drawings illustrate a ribbon feed mechanism which is similar to that employed in the Monarch typewriting machine, and which is explained in the United States patent to Jacob Felbel and Carl Gabrielson, No.

703,339, dated June 24th, 1902. Each ribbon spool 35 is carried by an upright shaft 37 which rotates in a fixed bearin 38 and has secured to its lower end a smal beveled gear 39. The gear 39 meshes with a beveled pinion 40 secured to the forward end ofa horizontal shaft 41 which shaft has its bearings in

lugs

42 and 43 depending from the under side of the top plate. The shaft 41 carries at its rear end a beveled pinion 44 which isadapted to mesh with a beveled from dri ving pinions 45 on the driving shaft 46. As explained in the above cited patent, the driving or power shaft 46 is capable of longitudinal movement and the longitudinal position of said shaft determines which driving pinion 45 will be in mesh with its co-- operating pinion 44 and which ribbon spool will be turned to wind the ribbon thereon.

Midway between the ribbon spools 35 the ribbon 36 is threaded through a ribbon cri- .brator or carrier 50 which is supported and ided in the upright arms 51 of a supportmg bracket 52 secured by screws 53 to the top plate of the machine. The lower portion of the vibrator or carrier 50 is bifurcated and carries a cross-pin 54 which is embraced by the slotted forward end of an operating lever fulcrumed at 56 in a lug 57 depending from the top plate. arm of the operating lever has formed in it an elongated slot 58 which receives a pin or stud 59 secured at the top of a ver- -tically' arranged link 60. The link 60 is made for convenience in. several parts which screw into one another or are otherwise suit ably secured together, and the upper part 61 of said link is flattened and, besides carrying the stud 59, is provided with a'downwardly and forwardly bent'arm' 62 (Fig. 3). At its lower. end the link 60 is pivoted at 63 to the arm 29 of the universal bar frame. The link 60 isadapted to be swung about the pivot 63 in order to cause the stud 59 to move longitudinally of the slot 58 so that said link may engage the operating lever 55 The rear at varying distances from its fulcrum 56 and thereby vary the throw of the ribbon carrier or vibrator 50. The means employed to swing the link 60 about its pivot 63'and longitudinally of the lever 55 comprises an eccentric controller or member designated as a whole by the numeral 64, which member is slidably mounted upon the driving shaft 46 and is adapted to cotiperate with thestrap formed near the top of the link 60.by the part 61 and its bent arm 62. The eccentric member 64 comprises an eccentric working face 65, a tapered or cam portion 66 and a sleeve portion 67, which latter is formed with a circumferential groove or depression 68. A screw 69 passes into the sleeve portion 67 of the. eccentric member 64 and enters an elongated slot or groove 70 in the driving shaft 46. The eccentric member 64 is thereby slidably connected with the driving or power shaft 46 and is caused to rotate by and with said shaft but may bemoved longitudinally of. said shaft without,- affecting the latter. The shaft 46-inay also be moved. endwise without affecting the member 64. Pivoted forwardly of the linkGO to the arm 29 of the universal bar frame at 7-1 is a two-part link 72, the upper portion of which is bentor off-set at 7 3 and 74 so that the flattened top part 7 5 of said link stands to the left and forwardly of the top of the link 60, and so that a stud 76 secured to said flattened ortion 75 is adapted to engage with the sot 58 of the operating lever at the left side of the latter and forwardly of the some:

stud 59 which engages-with the slot 58 at the right side of the operating lever. For most work the stud 76 stands normally out of engagement with the slotted operating lever 55. Thelinks 60 and 72 are capable of a slight movement transversely of the 7 operating lever 55 so. as to provide for the alternate engagement. of the

studs

59 and 76 of said links with the slot 58 in the oper ating lever. Ahorizontally disposed spiral 1 spring 77, having, one'end secured to the connecting rod28 and the other end to the link 60, tends to constantly swing the latter .rearwardly' about its pivot 63.

The movement of the link 60 slide designated as awhole by the numera 78 and best'seen in Fig. 8 of the drawings. The switching member 78 -comprises first a

longitudinal body ortion

79, 1 second an arm 80 'projecting orwardly from the top manner, as by soldering. The slot 81 is so shaped as to permit of the :insertion of the cyindrical lower portion of" the upperpart of the link- 72in assembling the arts, and

further to permit ,of the vertical p ay within I said slot of the flattened upper end 75, of said link 72 when the latter is recipro- "40 cated under the influence of the universal bar during the operation of the machine.

In assembling the mechanism the upper flat- 4 tened part 61 of the link 60 may be inserted between the sides of the wire loop 82, which latter may thereafter be riveted 1n thebody l ortion 79 of the switch- 7 8 in a manner best loop 82 under the influence ofthe eccentric faceand said part 61 may also.. move up and down transversely of the 100 when the;

, link 60 is reciprocated'by the universal bar.

-87 and at, the lower end in a fork 88 which The longitudinal movement of the jecontric member 64 is controlled by a second switching member 85 (F' 2),, which comprises a vertically dispose, arm- 86 terminatmg at the top in a perforated',collar portion fits into-and embraces the. gXoove or depression 68 in said eccentric member. The collar portion ever thesgvitch member 85 -fits' on the inner end of a 1111 and ush rod 8'9 and said collar portion is secure thereto b a headed screw 90. .Therod 89 extends horizontally beneath the top/plate and termitransversely of ,the operating lever 55 and the similar transverse movement of the other link 72' are controlled by a switching member or arm 105, the 'endwhereof is .natesnearthe right-hand side of the machine in a collar .91 provided with a forwardly extending pin 92,. .The rod 89 is surrounded for the greater part of its length by a sleeve- 93 which is, provided near its left-hand end withaspline 94'. The sleeve 93 has its bearings in the right-hand bearing lug 47 of the driving shaft ".46 and in a righ-tangled bracket 95' which is secured to the underside ,of the top plate by headed screws 96. The bracket 95 is slotted to permit of endwise play of the spline 94 therethrou' h, butthe said spline fits the slot in the racket 9,3

1 with suflicient snugnessto'prevent the sleeve in its'bearin although 93 from turnin it-move's freely ongitudinally t erein. The rod .89 'moves freely longitudinally'of. the

sleeve '93 which latter serves asa bearing for the said rod. As best shown in Fig, 4, the collar portion 84 of the switchin "mem ber' 73 fits over theinner or the 'le ,-h'a nd end of the sleeve 93-and is secured to said sleeve by a set'screw 97. The switching. member 7 8-is maintained constantly in a horizontal position, by-the spline 94 of the sleeve 93 with which latter the member 7 8- issecured in a fixed relation by a set screw 97. As seen in' Fig. 4, the collar portion 84 of the switchingmember 78 is positioned between the bracket 95 and the collar portion 87 of the switching member 85.

A collar 98 is fixedly secured to the sleeve 93, between the bracket 95 and the bearing v 47 of said sleeve, by a set screw. 99. A; t.

eoileds "rin 100 surrounds the sleeve93 between t e s eeve bearing 47 and the collar 98, which latter is'normally pressed by said spring against .the right-hand face of the bracket 95 thereby positioning the sleeve 93 and the switching member 78 mounted on said sleeve, as indicated in Fig. 4. I

As best seen in Figs. 9 and 4;, the pin'92 at the right hand end of the rod '89 is embraced by the fork of a bifurcated crank arm 101, the collar portion 102 whereof'is fixedly secured to the rear end of a horizontally dis- .indicated in Fig. 4 When so assembled, p a the part 61 may inovelongitudinally of the osed and forwardly extending rock shaft 103. The'horizontal ,portion ofthe .rock

shaft 103 extends through and terminates slightly in front ofthe front plate 104101? a handle or finger piece 106.

provided with he rock shaft 103 has its bearings in-beari'ng plates 107 I and-1108 which are respectively secured to the right hand lug's 42 and. 43 by headed screws 109. A collar 110is fixedly secured to the rock shaft 103 and abuts against the .forward face of the rear bearing late 108.

' Another collar 111 is fixed y secured in any suitable manner Yto/the" rock shaft and abutsagainst the rear faceof the forward bearing plate 107. The collars 110 and 111 serve to prevent endwise motion of the rock shaft 103.

Integral with the collar 111 is a positioningmember 112 which, as'herein shown, is in the form of a sectoral plate extending to the left and downwardly from the rock shaft and having its periphery formed with depressions or

notches

113, 114, 115 and 116. A check or locking spring 117 is fixedly secured to the under side of the top plate in any suitable manner and is adapted to en gage the depressions or notches in the positioning member 112.

The inner side of the crank arm 105 is adapted to cooperate with different faces or stop portions of a sto member 118 which comprises a perforate 01' stops 120; cut-aways or depressions 121 between the hub 119 and the side stops 120; and end faces or stops 122 and 123. The

' stop member 118 is fixedly connected, as

by a-driving fit or in any other suitable manner, with a knurledthumb wheel 124 whichis longitudinally perforated to receive a shouldered screw 125 which screws through portion of the screw 125, while the thumb, wheel 124'and the stop member 118 rotate: on the shouldered portion of said screw, being frictionally controlled by an annular cup-like spring plate 131 which is interposed between the rear face of the thumb wheel- 124 and the front face of the limiting stop 128, and is shown in detail in Fig. 15.

If the knurled thumb wheel 124 be turned so as to rotate the stop member 118 to the position indicated in Figs. 2 and9 and if,

by means of the handle 106, the rock shaft 103 be rotated leftward until the crank arm 105 contacts with the side stops 120, as indicated in said figures, the positioning memeber 112 will be rotated until its depression 11.3 is engaged by the locking spring or check 117 and the switching members '78 and 85 and'the parts associated with and controlled by them will be in the positions in dicated'in Figs. 2 and 4. With the parts so positioned, the ribbon will be fed' longitudinally and will also be; given a variable crosswise feed so that thef-type impressions will make a serpentine or wavy path lengthwise 'of the ribbon and extending from side to side thereof. If a ribbon of uniform hub 119 side faces charact er be in place on the machine, a ribbon having a plurality of fields of different characteristics may be substituted therefor in a known manner. A ribbon of the last named kind is represented in the drawings and indicated therein by the numeral 36.

longitudinal stripes or fields a and b and if these be colored, as hitherto suggested, respectively black and red, and the mechanism be allowed to remain in the relations indicated in Figs. 2 and 4, some of the type impressions will be printed in black, others in in red, givin a variegated or parti-colored effect which is sometimes desirable in ornamental typewriting. Usually, however, it is desired to print all the letters of a word or a succession of words in one color.

Suppose first that it be desired to print in black alone. The handle 106 is first swung wheel 124 the stop member 118 is rotated to the right to the position-indicated in Fig. 10, with the depressed part 121 in contact with the limiting lug 130, and finally the handle 106 is swung to the leftuntil the crank arm 105 contacts with the' end stop 122 when, as indicated in Fig. 10, the depression 114 of the positioning member 112 will be engaged by the'locking spring 117. Comparing Fig. 10 with Fig. 9 it will be noted that the rock shaft 103 has been rotated rightward through an are which is represented on the periphery of the sectoral positioning member 112 by the distance between the

depressions

113 and 114. This rotary movement of the rock shaft causes its rear crank arm 101, acting on the pin 92, to move the slide rod 89 endwise and through the sleeve 93 and thereby to draw the eccentric member 64 to the right to the position indicated .in Fig. 5 with the switch member in contact with the switching member 78. It will be apparent from j an inspect-ion of said figure that the eccentric face has been withdrawncompletely from its strap formed by the upper part. 61 of the link 60 and the forward bent arm 62 from its strap permits the draw spring 77 to swing the link 60 rearwardly about its pivot 63 until the part 61 contacts with the body portion 79 of the switch member 78, at which moment the stud 59 engages the operating lever at the greatest possible distance from the fulcrum 56 of said lever. If the print-ing devices be operated with the parts in the relations indicated in Fig. 5, the link 60 acting on the operating lever 55 at the furthest point. possible from the fulcrum 56 of the lever will swing the latter upward to the least height through which it can be thrown by said link 60 during the operation 1 of the machine. With the parts related as The' ribbon 36 is shown as made up of two.

red, and others partly in black and partly to the right, then by means of the thumb of said link. The separation of the eccentric last described, this upward movement of the lever is constant and unvarying and the mechan'ism is so proportioned that the ribbon vibrator is always thrown thereby so as to present the same part of the width of the ribbon to the action of the printing types. The path of the type impressions will be in a straight line longitudinal of the upper or black field (z of the ribbon.

Sometimes it is desirable. as in preparing stencils for minieograph work, to cause the types to strike directly against the stencil or other paper without the interpositioning of the ribbon between them. I have provided means to accomplish this result by mechan' ism which prevents either of the links or 72 from actuating the operating lever 55, so that the latter will remain quiescent in normal position during the operation of the printing keys. To accomplish this result the handle 106 is swung to the right and the stop member 118 rotated leftward to the position indicated in Fig. 11 with the depression 121m engagement with the limiting lug 130, after which the handle 106 is swung leftward until the crank arm 105 contacts with the end stop 123, which latter is at a distance from its center of rotation slightly greater than is the distance of the end stop 122 from said center. Consequently the rock shaft 103 is rotated a short distance to the right of the position indicated in Fig. 10 and the locking spring 117 disengaging from the notch 11 k engages with the notch 115 in the positicmiug member 112. During this rotary moven'ient of the rock shaft 103, its rear crank arm 101 pulls the slide rod 540 still further to the right and the switch 1nember 85, which it will be recalled. is

now in contact with the switch member 78. will act on the latter to pull it to the right against the pressure of the coiled spring 100.

the sleeve 93 moving longitudinally with the rod 89 and slidingthrongh the

bearings

47 and 95.

of the switch member 78 the upper portion of the link 00 which is controlled by the wire loop 82 will be swung transversely of the operating lever until the stud 59 is disen gaged from said lever, while at the same time the link 72 is swung to the right until its stud 76 stands but a short distance from the operating lever but out of engagement therewith. there being sufficient spring or give in the two links to permit of this movement. transversely of the operating lever. The parts will now be in the positions indicated in Fig. 13, neither link being engaged with the operating lever, so that when the printing devices are actuated. the ribbon vibrator will remain quiescent. in normal position and the ribbon will not be interposed between the types and the paper.

If it be desired to print only on the red stripe I) of the ribbon, the handle 100 is During this rightward movement swung rightward until the last notch or depression 116 of the positioning member e'ngages with the locking spring 117. the notch 116 and the locking spring 117 being so proportioned and related that the check forms a positive stop for the positioning member 112 and there is nodanger of overthrow. This further rotation of the rock shaft 103 causes the crank arm 101, acting on the slide rod 89, to draw the two

switch members

85 and 78 still further to the right to the position indicated in Fig. 7 thereby increasing the compression of the spring 100 and bringing the stud 76 into engagement. with the slot 58, and thus operatively connecting the link 72 with the operating lever The link '72 is guided and controlled by the slot 81 in the arm 80 so that said link always acts on the operating lever at a fixed distance from the fulcrum of the latter. The point at which the link 7 2 acts on the oper ating lever is nearer the fulcrum of the latter than is the point at which the link 60 acts on said lever when the parts are positioned as indicated in Fig. 5. The result is that the lever 55 has a constant swing under the influence of the link 72 which is greater than is the constant swing of the lever under the influence of the link 60, and under the influence of said link 72 the ribbon vibrator is swung to a greater height, the parts being proportioned so that the lower field or red stripe b of the ribbon will be presented at the printing point and the path of the types will be in a straight line longitudinal of said stripe 2)..

From the all red printing position last. explained. the mechanisn'i may be restored or returned successively into the neutral position indicated in Fig. 6. the all black positiontFig. 5), or the variegated or particolored position (Fig. 1). The con'ipresscd spring 100 acts to move the switch member 78 leftward from the all red position until it has reached normal position (Fig. .3). while the switch member 85 is positively actuated through the various return steps to the position indicated in Fig. l by the slide rod 89. The tapered portion (30 of the eccentric member 64 enables the latter to effect an easy and'certain reengagement with the. strap in the link 60.

.Uthough l have explained and'illustrated the various positions of the mechanism in the 'order in which they successively occur. it is to be understood that the devices may be operated many order desired. For ex". ample, the handle 100 may be swung from the position indicated in Fig. 0 to that indicated in Fig. 12, thereby passing directly from the parti-colored to the all red position, and vice versa; or the shift may be made from any other position to the desired position as necessity re uircs.

It is further to be um erstood that though I have explained the preferable mode of using the stop device 118 in commotion with the crank arm 105, yet said'stop device may be manipulated in any other manner as may be desired. For example, the crank arm 105 may be turned with one hand and simultaneously the stop device may be manipulated with the other hand, or the-stop device may be turned by the thumb wheel.v 1% thereby camming the crank arm 105 from, say, the position indicated in Fig. 9 to that in Fig. 10, or from that in Fig. 10 to that'in Fig. 11. Furthermore, if desired, the handle 106 may be manipulated Without employing the stop member 118 at all. The stop member 118 serves both as a stop affording a fixed abutment-for the crank arm 105 and also as an indicating means, being so proportioned that when turned to the various positions hitherto described it serves to indicate what section or part of the ribbon will be utilized when the crank arm 105 is brought into'contact with said stop member, hence I prefer the latter.

Various changes may be effected in the construction, combination and arrangements of parts, and some parts may be used Without other parts, all without departing from the spirit and scope of my invention.
