ALEXANDER Ti BROWN AND ARTHUR J. BRIGGS, Ol SYR 'ASSIGNOR TO SAID BROIW TYPE-WRITIN G MACHINE.

T all whom it may concern:

Be it.. known.- that we, ALEXANDER T. BROWN and ARTHUR J. Bmeos, citizens of the United States,.,and residents of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Typeriting Machines, of which the following is a specification.

Our invention relates to ink ribbonmechanism for use in printing devices and more especially in typewriting machines.

One object of our invention is to provide means for controlling an ink ribbon having longitudinal stripes or fields of different characteristics, such/for example, as a ribbon inked with inks of different colors.

Another object ofthe invention is to provide an iinprovedhieans for feeding an ink ribbon both transversely and longitudinally.

Anotherobject}is, ,to provide an improved reversingdcvice for an mk ribbon.

Other objects will appear hereinafter.

' The invention,consists in certain features of construction and combinations and ar ranqen ents of parts which will befully set forth herein and particularly pointed out in the clainis.

'lhe'ihvention s illustrated in the accompanying drawings in which,'

Figure l is a longitudinal vertical sectional view of a typem'iting machine having our in- Fig. 2 is a horizontal sectional view through a spring drum and certain gearing forming part of the driving mechanism of the ink ribbon. Fig. 3 is arear elevation ofthe machine. Fig. 4 is an iso metric viewof a part of the ribbon mechanism detached from the typewriting machine. F ig. 5 is an isometric viewof part of the ribbon mechanism; and Fig. 6 is a left-hand side elevation of a part of said mechanism.

The present invention is applicable to a variety of printing'devices, but it has been more especially designed for use in typewriting machines, and we have accordingly shown it applied to a Smith Premier ty ewriter. The 'main frame of this machine. comprises side plates 1 connected together by a back plate 2. Posts-3 rising from said side plates support a top plate 4 on which are rails 5 which support'a carriage 6 by means of ball or roller bearings. A platen 7 -is mounted on said carriage. Said carriage is drawn across the machine by a spring drum 8 to which it is cemnected by a strap 9.

Patented May 26, 1908.

A feed rack 10 mounted on the carriage nor 'mally engages a pinion 11 which is geared to a shaft 12 which, at its rear end, carries an escapement wheel 13 which cooperates with feed dogs 14 mounted on the upper end of'a vertical rock shaft 15 journaled in bearings on the top plate 4 and back plate 2. Said roc shaft 15 has near its lower end an arm 16 which is operated by arms 17 projecting from a universal bar or operated by arms 19 projecting from key operative rock shafts 20. Said rock shafts are journaled at their rear ends in the back plate 2 and at their forwardfiirls in angled frame...-

plates 21 which constitutes the keyboard of 7 the machine. The rock shaftsat their forward ends carryarms 22 which are ivoted to key stems 23 which pass loosely tirough ol'penings in the keyboard plates 21 and at t returning spring 25. Arms 26 projecting from the rock shafts are connected by' links '27 with type bars 28. The parts'above referred to are, or may be, of the well known construction ordinarily used in the Smith Premier machine.

A right-handribbon spool 29 and a left; hand ribbon spool 30 have hollow ,axles which are loosely mounted on rods 31: (Figs. 35

3 and 6) which extend between the posts 3. Said 'spools are automatically reciprocated axially along said rods 31. in order to impart -a transverse feed to the ribbon and theygaiiey.

also rotated on said rods ins-.order;.,to impart 90 when the spools are in position, stands ver- 100 tically and extends upward into a fore and aft slot formed in the top plate 4-, as best ap pears in Fig. 3. Within said slot, the yoke 35 of a as shown in Fi 3. Th'( construction is,

such that the ribbon spool and ts frame 32 are free to slide from fron to'back of the machine, but the frame 32 is prevented from gate 18 which is.

turning by the walls of the slot in the top 1i ien' upper ends carry character keys24. Each of the rock shafts is .irovided with a ribbon spool and 5 rod 50 .back of the hub 52.

plate, the yoke plate-34 cooperating with one of saidwalls and the cars 35 with the other. The upper edge of the plate 34 serves as a ribbon guide above the top plate, the ribbon being led across the machine beneath the platen from one of these plates to the other, thence downward through the slots in the top plate to the ribbon spools. f

As best shown in Figs. 1 and 3, the rear arm 33 of each frame 32 has projecting therefrom toward the middle of the machine, an arm 36 from which is bent ofl toward the rear of the machine an arm 37 having formed therein a vertical slot 38 into which'a pin a 39 projects from an arm 40 fixed to and rising from. a rock shaft 41. The rock shaft 41 extends transversely across the machine, being journaled on coned screws 42 threaded through the two rear posts 3. The con struction is such that if the rock shaft 41 be rocked back and forth the ribbon spools will be reciprocated, sliding axially on the rods 31. The rock shaft 41 is rocked for this purpose by an arm 43' projecting therefrom toward the rear of themachine and having a pitman 44 connected with its rear end, the upper end of said pitman being mounted on a wrist pin 45 projecting from the rear face of a wheel46 which is'geared'to the s ring drum 8. The longitudinal feed of the ri bon is efiected by a second pitman 47 connected with a wrist pin 48 projecting from the rear face of a whee149 which is also geared to the spring drum.

The train of gearing for operating the pitmen 44 and 47 will be'best understood by reference to Figs. 2 and 3. The spring-drum and said train of gearing are both mounted on a rod 50 extending through one of the rear posts 3 and secured in position by a set screw 51 threaded through said 0st and engaging a flattened face of said rod. The spring is not shown in Fig. 2, but its inner end is connected to the hub 52 of a toothed wheel 53 which is controlled by a suitable.

55 tally extending arm57 is mounted on the rod 50 to which it is rigidly connected by a pin 58 extending through the end of saidarm and into said rod. In the free end ofathe arm 57 is journaled a short shaft 59 on the 60 rear end of which isrigidly mounted a gear wheel 60 that mesheswith the gear wheel 56. The wheel 46 which actuates the itman 44, is rigidly mounted on the rear en of the shaft 59 and is secured on said shaft by aheaded screw 62 threaded into the end of the shaft. The pinion 49 which controls the pitman 47 meshes with the gear wheel 46 and is mounted or formed on the end of a short shaft '64 which is j ournaled in a longitudinal opening or hole formed in the end of the rod 50. In order to prevent the shaft 64 from slipping out of said hole a plate 65 is mounted on the rear faceof the gear 46, and said plate is of such diameter as to lap over the teeth of the pinion 49. The gear 46 has twice as many teeth as the pinion 49 so that said pinion makes two turns to one turn of the gear, a'ndconsequently the itman 47 makes two strokes to one stroke of the pitman 44. The-ratchet wheel 55 is engaged by a springpressed operating pawl 66 pivoted at 67 to the .rear face of the springtdrum 8 and also by a retaining pawl 68 pivoted on a shouldered and headed screw 69 threaded into therear end of the shaft 59. The pawl66 operates to turn the ratchet wheel 55 when the carriage is moving toward the left and the pawl 68 prevents rotation of said ratchet wheel in the op osite direction when the carriage is being drawn toward the right. The wrist pins 45 and 48 consist of shouldered and headed screws threaded eccentrically into the rear faces of the gear 46 and the pinion 49. It will be perceived that the pitmen 44 and 47 are operated whenever the carriage is moving toward the left but not when the carriage is moving toward the right. The pitman 44 is connected with the arm 43 by a universal joint. To this end a ball 7 O is formed or mounted on the rear end of said arm and the lower end of the link is formed with an opening having the general outline of a part of a sphere, the rear portion of said opening bein of less diameter than the diameter of the bal 70. A plate 71 is secured to the front face of the lower art of the pitman 44 by a screw 72 and sai plate is formed with an opening,

also havin the general outline of a portion of a s here, '0 e front part of said opening being of ess diameter than the diameter of the ball 70. The plate 71 being applied to the ball from the front and the link 44 being applied theretofrom the rear and said parts being secured together by the screw 7 2, the link has in effect an opening which is spherical and which cannot come off of the ball 70 but which is free to move thereon with a universal motion. r

The wrist pin '45 may obviously be placed at an desired distance from the center of the whee 46 so that any desired extent of transverse feed may be imparted to the ribbon. For example, said wrist pin may be so placed a as to move the ribbon spools such a distance as to utilize the whole width of the ribbon at eachreci rocationthereof. In the present instance, owever,-said wrist pin is set nearer to the center so as to impart a less extent of reciprocatory -motion to the ribbon spools and the ribbon is made witha plurality of longitudinal stripes or fields of different characteristics. For example, the forward part of the ribbon may be inked with black ink and the rear part with redink and such aj dili'erence is. indicated by the shadingon the ink ribbon in the drawing Itwill, of course, be understood thatthese fields may'difi'er in 1 other respects. For example one of them may be for copying ink and the other for record ink. 'In the present instance the ribbon is shown with two stripes or fields and the parts are so proportioned that a sufficient extent of transverse feed is imparted to the ribbon to utilize substantially the whole width of one of said, In order to provide for shifting the; ribbon from one'field to the other, the arm 48 is not rigidly mounted on the shaft 41, but is loosely mounted thereon and meansare provided for changing the relationship of this arm to said shaft and to the arms 40.- .As" ,the ribbon in the present case has two fields, provision is made for two-such relationships.

pulled-toward the front figure The left-hand arm 40 is-provided with an elongated hub, as best shown in Fig. 5, which hub is rigidly securcr'l to the shaft 41by a pin 73 projecting through said hub and shaft. he arm 43 is one arm of an angled lever ted on the shaft 41 in a slot 74 .a, ribbon having which is pivo (Fig. 5).formed in the h b of the arm 40. The other arm' 75 of said le er'extends downward and forward and hasi-a cam plate 76 pivoted thereto by a shouldered and headed screw 77. Said cam plate is formed with an eccentric cam slot 78 into which a pin 79 extends from an arm 80 projecting toward the front of the machine from thearm 40. Said arm 80 is drawn downward, tending tomove the ribbon spools toward the front of the machine", by a spring 81 which is connected at its upper end to an car 82 projecting from .the arnr80 and at its lower end to a pin 83 projecting from the arm 75 The cam slot 78 is formed at its ilpper end with a notch 84 into which the pin 79 is drawn by the spring 81 when the -cam plate is forced towardi-the front of the machine, th'us'retainin'g the parts in that position. The notch 84 is ofsuch form, however, that by applying force to the cam plate 76, said cam plate may be moved toward the back of the machine and the springfll will then draw lower end of the slot 78. In order to move the cam plate 76 to one or the other of its two positions, a rod 85 is pivoted thereto'at 86 and extends toward the front of the machine, having asliding bearing in a bracket '87 depending from one of the frame'plates 21.. The rod 85 is provided with a, handle 88 by which said rod may be ushed toward the back of the machine or pul ed toward the front of the machine. When said rod and the cam plate 76 are in their-rear position,

shown in" Eigs. 1 and 5, the pin 79 is in the 5 lower end of the cam slot 78, and the arms 46} 1 ribbon mechanism occupy their forward position with reference to the arin-43 and the ribbon has its rear field beneath the'p'rinting point; As thearnr 43 is rocked by it's pitnia'ii' t l' with the parts in this position, "thearin 4O will oscillate between its-extreme-rear position, shown in full itsextreme forward position, shown in dotted lines in said figure-and the transverse feed of the ribbon will be confined to the red field; If the handle 88 be 7 of the machine until j the-pin 79 is seated in the notch 84, the arms 40 willbe tilted back with relation t )-"tlie arn'i 43 as shown in Fig. 6, and tlTeriblion spools will be moved to bring the black V ribbon into ii's'e. When the? 'arin "43* is rocked by. its pitman with theparts in this positlon, the arms '10 will oscillate between their extreme rear positions, shown by full lines in Fig. 6 and their extreme forward positions,'s-hown by dotted'lines in said 'the' transverse ed of t e lithe-n will be restricted to the black field. In case but one-kind of inkis used, the operator will occasionally shift it from one field to the other so as to getthe use of the entire surface of the ribbon. I, By an inspection of Figs. 1 and 6 it will be observed that when the parts are in the position shown in the latter of'said figures, in which the black stripe of the ribbon is in'use, a line drawn from the center of the shaft 41, perpendicular to the shaft-31, will nearly bisectthe angle between the two extreme positions of the arm to impart a. transverse; feed to'the ribbon In this position of the arts, therefore, said ribbon receives a maximum extent of transverse feed; When the parts are in the position shown in Fig. 1, with the red stripe of the ribbon in use,the arm- 40 forms an-obtuse angle with the axis of the ribbonspool. AS said arm 40 is rocked through the same angle in both instances, it isevidentLthzit in the latter case a less extent of transverse feed will "be imparted to the ribbon than in the former case. It will be perceived therefore, that means are provided for imparting a" reciprocatory transverse feed to theribbon within either one of a plurality of widthwise 5 5 r --fields and that the the pin 79 to 'the wh'en the other is in use.

tage in a device of this character because in 1 most instances where polychrome ribbons 1 20- are used one sortof extent of this reciprocatory feed is less when one fieldis in use than This is an'advanf ink is used less than the other. In the instance here given as Jan-o illustration, where one stripe of'the ribbeni is red and the otherblack, the black ink would ordinarily be used a good deal-morethan the red ink so that it is an advantage 3 up have the black stripe wider than there-d s n .e. r 1 r Soffar as we are aware, it is broadly'new in to provide means for im- 40' as said arm is rocked m of transverse reci rocatory' fee'd imparted I 19 whatever may be the character of said ink are aware it is new to effect this difference 20 which have bent ofi' portions 90 adapted to end with a rearwardly extending part 95,an opening in which is plugged with a'disk of 40 hereinafter, means are provided for holding .ment with its ratchet wheel.

In the present instance this difference in the extent of transverse feed is effected by changin the relation of the parts of the transverse eeding means, but as far as we by any means whatever.

In order to impart a longitudinal feed to the ribbon the pitman 47 is operatively con nected'with two pawls 89, the upper ends ofengage ratchet teeth 91 extending, crowntooth fashion, from the front face of the front flange of each of the ribbonspools.

of arms 93 which-are fixed on and extend toshaft 94. Said rock shaft"'94 extends across the machine beneath the system of rock coned screws threaded throu h the side plates 1 or said rock shaft may e journaled in said side plates in any suitable manner. Each of the pawls 89 is formed near its lower lead 96, thus wei hting said lever and causing it to tend to fill by gravity into engagement with its ratchet wheel. As will appear one or the other of the pawls out of engage It will be obvi us that if preferred the pawls may be pressed toward the ratchet wheel by springs stance. An arm 97" fixed to and rising from one end of therockshaft 94, llitSPlVOtGll thereto on a shouldered and headed screw 98, a link 9' which extends upward and toward the back of the machine, its rear end being tending arm 102 which is connected with the pitman 47in thesaine manner as the arm 43 to the pitlnan 44. The lever 101, 102 is piv oted onthe rock shaft 41. In order to atlord a wide bearing for said lever. and to prevent motion thereof e'ndwis'e of the shaft 41, said lever'is mounted on said shaft just-to the the arm 101'"'has bent off therefronran arm 103 arallel with the shaft 41 and said arm 103 is again bent, forming an arm 104 which is pivoted'on the rock shaft 41 to the right of the arm 40'. The construction is such that as the pinion 49 is rotated and the pitman I? rcciprocated, the lever 101, 102 is rocked, thus rocking the shaft 94 by means of the link 99, and moving the pawls 89 up Both pawls operate on and down in unison. the inner sides of their respective ratchets and their tip-strokes are their operating strokes in both instances. As the up-stroke of the pawls S9 is effected on the down-stroke of the pitman 47,'that one of the ribbon spools which has its pawl in engagement with its ratchet will be turned-a short distance to feed the ribbon longitudinally upon each down-stroke of the pitman' 47. been said above the pitman'47 makes two strokes to one stroke of the pitman 14. The, parts are so arranged that thc'pitnmn 4:7 is about in the middle of its operating stroke at the moment when thcpitman 41-is on'the dead center, so that the longitudinal feed of the ribbon begins just before the ribbon has reachcdohe end-of one of its reciprocations andreaches its'inaxi'ni-um velocity just at the end ofsaid reciprocation and is, com pletedsoo'n after the beginning of the transverse motion of-the ribbon in the other direction. Obviously, as the pinion -12) makes one turn to each half turn of thc gear l6, the pitinan 47 will make an operating stroke at about the time when the pitman 44 is at the limit of down-stroke and another at about the time when the pitman 41 is at the end of its-up-strokc, so that a longitudinal feed will be imparted to the ribbon at each end of each transverse reciprocation thereof. In Fig. 3 the pitman' 47 1s shown about at the end of its operating stroke and the pitman 44 a little past the dead center on the beginning of its tip-stroke. In this position of the parts one step of longitudinal feed has just been completed. The pawls are of considerable length and followthe spools in their axial motion so that one of said pawls is always in operative position whether the spools are set to use the red field or the black field.

.In order to reverse the direction of longitudinal feed of the ribbon we have provided means for holding one. or the other of the pawls SQtoward the front of the machine, and out of engagement with the ratchet. Said means comprises two arms or levers 105 having hubs 10(5journaled on the rock shaft Said hubs are hcldagzunst endwrsc mo 94. tion in one direction by the hubs of the arms 93 and lu the other direction by collars 107 secured to the rock shaft 01 by et screws.

Each of the arms or levers 105 at its upper end is bent. to form a long loop 108 through which one of the pawls 80 passes. The loops 108 are closed at the rcar'so hat if one of the "drills-105 be drawn toward the front of the machine it will draw the pawl 89 away from its ratchet and said awl will play idly up and downin said loop w ien the machine is in. op-

Ash s the machine.

oration. In order to control the levers 105 so as to cause one of them to occupy its rear position, permitting its pawl to operate on its-ratchet when the other occupies its forward posit-ion holding its pawl inoperative,

each of said levers has a forwardly extending arm 109 to which is )ivoted at 110 an upwardly extending link 111. A rock shaft 112'is pivoted at-its ends to the side plates 1 and extends across the machine above the system of key operated rock shafts 20. Two upwardly extending arms 113 are rigidly mounted on said rock shaft 112, one near ea -h end thereof. To this end each of said arms is provided with a hub 114 which is secured to the rock shaft 112 bya set screw-1 15. One of the arms 113 has an arm 116 extending therefrom toward the rear of theiiiaehine and one of the links 11 per end to this arm.- The other of the arms 113 has an arm 117 extendingtherefrom toward the front of the machine and'the other of the links 11.1 is pivoted at its upper end to this arm 117. The construction is such that if the shaft 112 be rocked toward the rear of x v the arm 116 will depress its link 111 and rock' the arm 105 toward the front of the machine. At the same time, the

arm 1 17 will eleva to its link 111 and move its arm 105 toward the rear of the machine. If the rock shaft be rocked toward the front of the machine, the arm 116 will rise and the arm 117 will be depressed, thus reversing the relative positions of the two arms 105 and moving to inoperative position that pawl which was before .in operative position and permitting the other pawl to fall to operative position, thus reversing the direction of feed of the ribbon. A handle 113 is mounted on one of the arms 113 so that the shaft 11.2 may be rocked by hand. In order to yield. ingly retain the rock shaft. 112 in either of its two positions, -the arm 11? is extended and the forward free end thereof is beveled inboth directions, as shown at 1 19; the pointed end 119 thus formed is engaged byroller 121') journaled in the free end of a spring arm 121 which depends 'fl'OIil one of the frame plates 21. The roller 121) will yield mit the. pointed end 11.) of .the arm 117 to pass it in either direction if sufficient force be applied. to said arm, but said roller will retain the arm in either of its positions. in

' order to limit the forward movement of the pawls 8!), each of the arms 11?) has projecting therefrom a bracket- 122 which stands in the path of a part of the pawl when said pawl is moved away from its ratchet wheel.

We have provided means for automatically reversing the fcedof the ink ribbon wl'ienever 'said ribbon .is exhausted from one of the spools. Each of the ribbon spools 29 and has a drum portion 12.; on which the ribbon is wound and which is formed with an opening 12-1- (l*ig. into which an arm orarms 1 is pivoted at its upi to per- I 125 of a plate 126 are adapted to drop when the ribbon is exhausted from the spool. The plate 126 is mounted on arock shaft 127 which lies parallel tothe axis of the ribbon spool and is journaled in the arms The plate 126 is secured to the rock shaft1127by rivets 128. Each of the shafts 127. proj ects through the forward one of the arms 33 and is bent off to form an arm 129. Each. ofthe arms 11.3 on the rock shaft 112 has at=its upper end an arm 130 extending therefromtoward the back of the machine and said arm. 130 has formed thereon two lugs 131 and 132, the latter being nearer the'frontof the machine than theformer. The operation of this device in the case of therightshand ribbon spool is as follows When the ribbon .iswound on this spool the arms 125 of the plate.

126 ride out of the openings 12.4 onto the drum 123 and with the first turn of the spool said arms rest on the ribbon itself, which thus closes the openings 124.. hen the ribbon is being fed off of this particular spool, the arms 125 will rest on the ribbon until the last turn of the spool, when, this portion of the drum 123 being now exposed, the arms 125 will drop into the openings 124.

The partsare so proportioned that when said arms drop into said openings the free end of the arm 129 moves toward the middle of the machine to such an extent thatit stands behind one of the lugs 131 or 132 on the arm 130. \'\"he I,i\-. the' spool is next moved toward the front of the machine in the course of its transverse feed, the arm 129 engaging the lug pushes the arm 113 toward the front (if-the machine, thus rocking the rock shaft 112 and moving the left-hand pawl 89- out of engagement with its ratchet and permitting the right-hand pawl 81) to drop into engagement with its ratchet, thus reversing the longitudinal feed. if the ribbon spools are set to use the forward stripe or field, the arm 129 will engage the rear lug 131; but if the spools are set to use the rear stripe or field of the ribbon said arm will engage the forward lug 132, so that the reverse will take place equally well whichever field of the ribbon happens It will be perto be in use at. the time.

ceived that the reverse is-effected by the transverse feed of the ribbon be effected when pither field of the ribbon is in use. If the ribbon were made with only one field so that the transverse feed extended the, whole width of the ribbon it is obvious that but one of the lugs 131 or 132 would be necessary. more than two fields a corresponding number of such lugs would be provided. The construction and operation of the reversing mechanism for the left-hand ribbon spool are substantially identical with that for the right-hand ribbon spool, except for the fact that the left-hand spool is arranged to move. its arm 113 toward the rear of the machine.

and that it may Furtl'iermore, if the ribbon had I Consequently the arm 129 connected with the left-hand spool drops in front of the lug 131 or 132 instead of behindsaid lug as in the case of theright-harid spool. The arms 113 the right hand arm, as will be understood.

The forward faces of the lugs on the righthand arm and the rear faces of the lugs on the left-hand arm are made beveled so that in case the arms 125 drop into the openings 124 when the arm 129 is forward of the In in the case of the right hand spool, or bac of the lug in the case of the left-hand spool, said arm will ride over the lug as the spool is reciprocated by the transverse feed-mechanism.

Various changes may be made in the details of construction and arrangements of parts without departing from our invention.
