'IIYIPIll-WRIITINGA MACHINE.

ASpecification of Letters Patent.

Application led October 184, 1917. Serial No. 197,214. v

To all whom z't may concern:

Be it knownA that I, HERBERT A. CARHART, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain y -new and useful Improvements in Type- Writing .Machines of which the following is a specification.

My invention relates to typewriting machines, and more particularly to means for automatically bringing.,r one or another of two different color fields of a ribbon into use at a predetermined vpoint or points in the travel of the carriage.

.One of the main objects of my invention, generally stated, is to provide improved and efficient means of the character specified.

A further object of the invention is to provide simple and eiiicient devices that may be readily embodied in existing machines on the market and operate in conjunction therewith to effect the purposes stated above without modifying the structural features of said machine as they now exist, otherv than by the'addition of my devices to operate in combination therewith.

Generally stated, my invention is intended to accomplish the same general ends that are attained by the constructions disclosed in the Patents Nos. 878,163; 878,573; 878,574; and 880,591, granted to Herbert H. Steele, and on whichthe present invention may be regarded as an improvement.

The invention in the present instance is embodied in a No. 11 Remington machine equipped with the usual key set denominational tabulator, and in which the invention may be readily incorporated without modifying the structural features of said machine. It should be understood, however that from certain aspects of my invention it may be embodied in various styles of machines, and that various changes may be made in effecting such embodiment.

To the above and other' ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and -jtrticularly pointed out in the appended claims.

In the drawings wherein like reference characters indicate corresponding parts in the different views, l

Figure 1 is a fragmentary side elevation,

partly in section, of one form of typewriting machine embodying my invention, only so much of the machine being shown as may bernecessary to arrive at an understanding of my invention.

.Fig 2 is a detail fragmentary perspective v1ew of the ribbon controlling mechanism and some of the associated parts.

Fig. 3 is a fragmentary top plan view of the machine with parts omitted.

Flgs. 4 and 5 are respectively detail side and bottom edge views of one of the controlling devices or cams.

Figs. Gand 7 are respectively detail side and bottom edge views of another and different form of controlling device or cam.

The polychrome mechanism disclosed in the accompanying drawings, aside from the means for automatically shifting it during the travel of the carriage, is the same as that embodied in the No. 11 Remington machine. Such mechanism is shown and described in the patent granted to John H. Barr, Sepamber 11, 1915, No. 1,153,668.

The frame of the machine comprises a base 1, corner posts 2 and a top plate 3. A power driven carriage, designated as a whole by the reference numeral 4, is mounted on anti-friction rollers 5 to move from side to side of the machine over the top plate. A platen frame 6 is connected with Athe carriage by a link 7 and carries a cylindrical platen 8 which is supported in the usual manner by a shift rail 9 controlled by the ordinary case shift means, not shown, to effect a case shift movement of the platen frame and platen on the carriage.

Each of the printingkey levers 10 is fulcrumed at 11 in the base of the machine and is provided with a finger key 12. A link 13 connects each key lever 10 with a sublever 14, alink 15 forming a connection between each sub-lever and its type bar 16. The type bars are segmentally arranged and pivoted on a segment or support 17 to swing upwardly and rearwardly to strike against the front face of the platen 8.

A universal bar 18 extends beneath the Various printing key levers 10 and is connected at its ends to depending links 19 pivoted at their upper ends to crank arms 20 which project rearwardly from a rock shaft 21 mounted to turn -on pivot screws in the base of the machine. ing crank arm 22 on the rock shaft is con- Patented July 9, 1918.

An arm 28 which is in the nature of a sheet metal plate is adjustably secured to the arm by a set'screw 29 and a pivot screw 30, the adjustment of the arm bem'g around the pivot screw as a center. he plate 1s slotted to receive the stem of a screw 29, whereas the head thereof bears against the plate and holds it in its adjusted position relatively to the arm 25. A set screvvr 29 is also provided to retain the plante 28 1n the position to which it may be adjusted relatively to the arm 25. This set screw 29Il 1s received in a tapped opening in ,an off-set 'earon the armi 25 and at its lower end enf gages an oil-set shoe 29b carried by the plate 28 and extending beneath the set screw. The upper end of the arm formed by the plate 28 is slotted at 31 where it is received .1n a peripheral groove 32 (see Eig. 2) in a sleeve or collar 32'.l that is free toturn and slide -on a cross pin 33 of the ribbon vibrator actuator mechanism to be hereinafter described. It will be understood, therefore,

that each depression of l fective to rock the shaft 21, and thereby actuate the ribbon vibrator operating mecha# nism through the cross pin 33, and is also effective to actuate the escapement mechanism throughthe link 27. Y

A bi-color inking ribbon 34 may -be assumed to be divided into two longitudinally extending color fields, a black upper field or stripe a and a red lower field or vstripe b. This ribbon is carried and fed longitudinally by the usual ribbon spools and associated ribbon mechanism, not shown, and is led upward from the spools through openb ings 35 in the top plate, thence over sta-vl tionary guides 36- and through guide open,- ings in the head or upper portion of a ribbon carrier or vibrator comprising the usual parallel guide loops 37 rising from the body portion 38 of the vibrator.

j Referring to Fig. 2, it will be seen that the lower end of the ribbon vibrator 37, 38 is pivotally connected at 47 to thevcentrally disposed arm 48 of a bell crank lever 49. This lever further comprises a downwardly extending angular arm' 50 and a cross arm or brace 5 1 connects the two Aarms and stii'ens the member as a whole. The arm 48 divides into two branches which. terminate in ears that iit over a rod 52 and bear pivotally thereon, said rod providin a fulcrum for'the bell crank. The r 52 is mounted on a bracket 53 that is secured. by

A centrally rearwardly therefrom.

a printing key is ef- V77 with the lever f 1,271,eee

screws 54 to the Nshift rail -9 and comprises a portion extending rearwardly below the shlfty rail and .a forwardly and upwardly inclined portion which is provided with a tongue or lip 55 into which is threaded a headed shouldered screw 56. This screw serves 'as a uide for the ribbon vibrator, the sheet meta body portion 38 whereof is formed with a slot 57 which receives the screw and coperates with the same to guide 4the vibrator when it is moved'up and down during printing operations.

he devices'for actuating the operating y lever or member 49 are' mountedon a bracket 58 which, as shown in Fig. 2, is detachably secured by screws 59 to the rear of the type bar support 17. Said bracket has a downward extension 58a slotted to receive one of the screws 59. The slots in the bracket 58 which receive the screws 59 (only one of which is shown) are open at their lower ends so that by loosening'the screws the bracket, together with the parts which it supports, may be vertically adjusted. Said bracket is provided with rearwardly bent parallel ears 60 which receive a rod 61 on which the vactuating devices are pivotally mounted.

In the course 61 on the bracket, the parts for which said rod provides a pivot are also assembled in place. These parts comprise two actuators or levers 6,5 and 66 which have a common of the assembling of the rod plvot, being arranged to turn or fulcrum 4 on the rod 61 between the ears 60. The lever or member 6 5 isv provided near its lower end with across portion 67, which yterminates in forwardly bent ears 68, while the lever .66 has a cross portion 69 terminating in rearwardly b ent ears 70. The two sets of ears are perforated sothat the rod 61 may. pass-through them. The cross portions 69 and 67 are ofsuch length that the ears 70 j are embraced loosely between 4the -ears 68, while these latter ears are, loosely confined etween the ears '60 of the bracket 58. The lever 65 is constantly connected with the downwardly extending` arm 50 of the operating bell crank by a link 71, while the lever 66 is constantly connected to the arm 50 by a link 72. The link 71 is above the link 72 and at its forward end is pivotally connected, as by a shouldered screw 73, with an ear 74 bent forward from the side of the lever 65 at its upper end. The rear ,end of the link 71 is pivotally connected by a shouldered screw 75` with an ear 76 bent rearward from the arm 50 about midway of its length. Thelink 72 is pivotally connected at its forward 'end by a shouldered screw 66, said shouldered screw being threaded in Ward from .the'lever 66 somewhat below its lupper end. The rear end of the link 72 is pivotally connected by a shouldered screw an, ear 78 and bent for- Lampes,

79 with an ear 80 bent backward'from the arm 50 at its lower end,vsaid ear 80 being at the lopposite side edge of said arm from the ear 76. The links 71 and 72 incline downwardly and rearwardly from their respective pivotal connections-73 .and 77'so that they are at angles to a horizontal line passing through these pivots. Said pivots, during the platen shifting operation, remain stationary since the levers 65 and 66 are mounted on a-stationary support. During the shift of the platen the rear ends of said links are moved upward, being carried by the operating lever 49 which is support'- ed from the platen shifting frame. The links are so disposed that during the platen shifting operation they cross the yhorizontal or media-n lines and at the end of ,said operation are at the same angle to saidv lines but above them as normally they are below them. It will-be observed that as a resultI of the platen shifting operation the ribbon vibrator operating lever`49 and the links 71 and 72 are moved or shifted, but the elements of the ribbon vibrator mechanism be-l low said links are not affected by the shift; It will be seen that the pair of links 71 and 72 are at all times constarntly connected to the parts linked together by the links, viz., the arm 50 and the respective levers or actuators 65 and 66. It will also be noted that the two key operated actuators or levers 65 and 66 are constantly connected independently of each other to the vibrator. While the actuators 65 and66 are constantly connected with the operating lever 49, means are provided for rendering them separately or alternately effective kat will to operate said lever, said means comprising a rocking frame or actuating lever member, designated as a whole by the reference numeral 81. The frame 81 is rectangular in shape and comprises a sheet meta-l portion bent into a U- shape and inverted, providing a cross member 82 and parallel side portions 83, the

side portions being connected at their lower ends by the cross rod or pin 33 hereinbefore referred to. The side portions are perforated and reinforced with bosses or hubs 85 to iit over and bear both rotatably and slidably ou the rod 61, being -thus mounted co-axially with the actuators 65 and 66. The upper cross portion 82 of the frame is rectangular in shape. This rectangular part is cut out, providing an opening or slot 86 near the right-hand side, and a smaller opening 87 at the left-hand forward corner. Between these openings at. the front side is a triangular lug 88 which approaches closely a lug or thickened portion 89 at the left-hand rear corner of the frame.

The space between the lugs 88 and 89 provides a narrow7 opening, passageway or throat 90 connecting the slots 86 and 87, and within which the upper portion of the levers 65 and 66 are 'adapted to be separately disposed or loosely confined when it is desired to render them operative. The forward edge 91 of the lug 89 is adapted to operate as anactuating surface. The construction is such that by effecting a relative shifting movement between the frame 81 and the actuators 65 and. 66, either actuator may be brought within the passageway 90 and thereby rendered operative, being swung forward operatively when the frame is rocked, while the other lever is left free or inoperative. Thus a rocking of the shaft 21 causes the arm 28 to swing the frame 81 pivotally about the rod 61 as a center and co-axially with the levers 65 and 66, whatever may be the position of said frame endwise of said rod.

In the present instance the relative shift or resetting between the frame 81 and the two actuators is preferably effected by shifting the frame endwise bark and forth on the rod 61 so as to select the actuator to be operatively vibrated. Thus to shift or variably move the frame 81 endwise hand operated means are provided, comprising a link or arm 94 curved upward at its inner end and terminating in a forwardly bent portion which engages loosely in a slot formed in a lateral ear 95, projecting outwardly from the left-hand side portion 83 behind the pivot 61, so that the vibratory movements of the frame 81 will only slightly affect the link 94. The outer or left-hand end of the link or bar 94 is pivotally connected at 96 to the crank arm 97, ixed to and projecting downward from the rear end portion of a rock shaft 98 extending fore and aft of the machine at its left-hand side. Behind the crank arm the rock `shaft bears in an angular bracket or arm 99 which is secured to the type bar segment 17. The y forward end portion of the rock shaft'bears in a plate 101 secured to the leftehand front post 2 of the machine. In front of the post the rock shaft is provided with a knul-led button or vfinger piece 103. Behind the arm 99 the rock shaft has fixed to it an upstanding spring finger 104 having a head formed with holes 105,. which are adapted to coperate with a lug or projection 106 on the forward face of the arm 99, so as hold the rock shaft 98 and the connected parts, including the frame 81, in adjusted or set positions.

Indicating devices are preferably provided for facilitating the proper adjustment of the ribbon throw varying mechanism, said devices comprising suitable indicating marks or colors 107 on the front face of the plate 101. A pointer 108 is fixed to the rock shaft 98 to coperate with these indicating marks. The middle mark 107 corresponds to the upper field a of the ribbon 34 and the lower mark 107 to lower or red field When the pointer 108 is opposite the middle indicating mark the. shaft 98 will be locked against further turnlng movement in Clockwise. direction by a movable stop usually provided, but whlch 1s not shown in the present instance. 'When the movable stop is moved to an lnoperative position, this permits a further turning of the shaft 98 until the polnter 108 1s brought opposite the top indicating mark 107, at which time the ribbon throw changing parts controlled by the button 103 will be adjusted so that they will be inactlve at prlnting operations, or, otherwise expressed, will be in` mimeograph position as herelnafter more fully explained. In order positively to limit the dili'eren extents of throwing movement of the ribbon, stop devices are provided comprising a stop plate 115, which is arranged on the top of the usual spacing plate 116, secured to the'upper face of the type bar segment 17. The stop plate 115 is provided with a longitudinal slot 117 which receives a headed screw 118 by which the plate is adjustably secured to its stationary support, viz., the segment 17. Therear end of the plate 115 is turned down to provide a vertical stop face proper 1151, which is always in the path of the forward end of the part 82 of the vibratory member or frame 81 and always arrests said frame at the' same point in its movement.

Assuming the parts to be adjusted as in Fig. 2, it will be understood that when a printing key is depressed, the shaft 21 will be rocked as usual and will cause the arm 28, acting on the rod or frame 81 on its fulcrum. The upper portion of the frame moving forward will actuate the lever 66, Whose upper end at this time is embraced within the passageway 90 so that the edge 91 will act to push said lever 66 forward, the lever 66 becoming in effect a part of the frame 81. At this time the lever 65 will be in the openingl 86 and will be inactive, although it will swingy idly forward as a result of the movement imparted to the operating lever through its connection 72 with the lever 66. As a result of this movement of the operating lever the vibrator will be lifted to interpose the printing portion or field a of the ribbon in thek path of the actuated type bar. The parts are so proportioned and adjusted that when the front edge of the part 82 strikes the stop 115, thus positively arresting the vibrator andconnected train of actuating devices, the upper edge portion or-ield a of the ribbon will be presented opposite the printing point. This same extent of movement will be communicated at each vibratory movement of the ribbon as long as the parts are maintained adjusted as described, so that the type depressions will follow a i straight pin 33, to swing the -idly path longitudinally of, and about centrally of, the upperv field a.

When it is desired to use the lower ribl bon fieldb the fngerbutton 103 is turned counter-clockwise, acting throu h the shaft 98, crank arm 97 and bar or lin i 94, to slide the frame 8l bodily rightward. The frame will fbe maintained in this new position as inthe previous position by the detent devices 104, 106. Asa resul-t of this adjustment the passageway 90 will be caused to embrace the upper end of the lever 65, while the lever 66 will be located in the opening 87. Consequently, wheny the frame 81 is actuated during printingoperations the edge 91, acting against the same, and the motion from said levers `Will be transmitted through the link 71 'to the operating lever 49. At the start the edge 91 will fbe in contact with the lever 66 but the motion of this lever at this time will be so rapid, owing to the fact that it is being pushed 'by the arm 50 which is being pulled by the link 71, that the lever 66 will move forward away from the edge 91. As before the movement of the parts will be arrested by the contact of the edge of the part 82 with the stop 115, but though the movement of the frame 81 is constant, the movement transmitted from it. through the lever 65 to the vibrator will be' greater than the lmovement transmitted through the lever 66,

for the reason that the lever 65 is longer and transmits a greater movement to the link 71 .than the lever 66 transmits to the linkv72, and also because the link 7.1. acts closer to the fulcrum of the operating lever than does the link 72. The parts are so proportioned and adjusted that as a result of the longer throw transmitted to the vibrator the lower red ribbon field b will be presented to the types. Both in this adjustment of the parts and in the prior described adjustment of 4the parts, they will be restored to normal position chiefly by gravity when the printing keys are released, although the rock shaft returning spring 23 will act on the rock shaft 21 and arm 28, as well as on the universal bar, to restore the parts.

en it is desired to set the parts for mimeographing, the stop member, hereinbefore referred to and which is not shown, is lifted as described and the linger piece 103 is turned until the pointer 108 is brought opposite the top indicating mark 107. This movement o-f the rock shaft transmitted to the frame 81 through the described train of connections, will cause the frame to be slid bodily leftward along its fulcrum rod 61. As a result of this adjustmentboth levers 65 and 66 will be maintained simultaneously in the opening 86, so that at printing operations the frame 81 will be caused to swing lever 65 or 66. Therefore these levers, to-

on its pivot without affecting either' the lever 65, will operate "ing lever 49, lwill remair motionless in noragainst the `paper or work sheet on the--V in their path. .l

The riibbon controlling mechanism thus far described -is the same as that employed -mal -position so that the types may strike platen without .the ribbon being linterposed in the Remington machine, and in'order that this mechanism may be automatically controlled to bring one or another of the two 4 printing fields a and b ofthe ribbon lnto use. fat a predeterminedgpoint or points 1n the travel of the carriage, I have provided' in conjunction with said mechanism the following means:-A depending crank 'arm 119 is secured to the shaft 98 and is connected 'by a link 120 to acrank arm 121-which eX- tends forward from an upright rock-shaftl 122. Thevarm'121 has a lhub 123 which is adjustably secured to the shaft 122'by a set screw 124. This screw is received in' atapped opening in the'hu'b and IIbears at its inner end against the shaft. The lower end of the shaft is receivedin a bearing opening in an arm 125 of a bracket 126. This bracket is secured by screws 127 to the base of the machine, only oneof thescrews showing -in Fig. 2. From an inspectionof Fig. lit will be seen that the hub 123 receives a bearing on the upper side ofthe .bracket arm 125- and supports the rock shaft 122 and the part's carried thereby in position, whereas a collar 128 surrounds the shaft beneath the bracket arm and prevents the shaft from being dis'- placed upwardly in its bearing. A set screw 130 which projects from a bracket plate 131 secured to the top plate by screws 132. The

upper end of the shaft carries a controlling member which is in the nature of a crank arm 133 fixed on the shaft and extending horizontally therefrom in the general direction of the travel of the carriage. The outer end of this arm carries an upwardly projecting antifriction roller v134, carried on lthe arm by a shouldered pivot screw 135.

' In order to automatically shift the free end of this crank arm 133, either forward or backward at a given point or points in the travel of the carriage, and thus automatically cause a change in the use of the color field employed, I provide any desired number of tappets or cams such as are shown in Figs. 4 to 7, inclusive. The tappet or cam, designated as a whole by the reference numeral 136, is shown in det-ail in Figs. 4 and 5. This tappet comprises a fiat sheet metal body portion formed like ordinary column stops with two arms 137 that are adapted to straddlc a rod or bar 138 and be received in' interdental Aspa-ces 139 on :opposite :sides of vthe rod. A spring 140,` `such Vasis usually'employed on column stops, may .begttached to each member 136 to holdl it against accidental displacement from the bar 138. Extending rearwardly from the body portion of each member 136 is an arm which is bentto form two cam faces 141.and 142 at right angles to each other and inclined to the line of travel of the tappet and, generally speaking, facing away from the body portion thereof. When a member 136 is in \Qperative position on the bar 138, it travels with the carriage, and in the movement of the latter Afrom right to left the cam face 142, when broughtinto engagement with the roller 134, will shift-or cam the free end of the arm 133 rearwardly from the posit-ion to right the cam face 141 on the member 136 will co-act with the roller 134 to shift it out of its path whenever 4the latter is in the path of such cam, and thus preventthese parts from obstructing the movement of the carriage.

In Figs. -6 and 7 I have .shown a form of tap-pet or cam .for moving the arm 133 in the opposite direction to automatically shift the mechanism so as to write with 'the black vfield a of the ribbon. This tappetis designated as a whole by the reference numeral 143 and the body thereof is constructed like that previously described so that the member may be adjusted to any point along the bar 138. The tappet` 143'has a rearwardly projecting arm 144 which at its endis formed with'depending cams 145 and 146,

disposed at right angles to each other and Iin opposite direction from-the cam faces 141 and 142 and, generally speaking, facing toward the body portion of the tappet. The cams 141 and 142 and the cams 145 and 146 on their respective tappets join and form an apex at their juncture. In the movement of the carriage from right to left the'cam face izo 146 on each member 143, when brought against the rear side of the roller 134, will cam the free end of the arm 133 forwardly to the position shown in Fig. 2.l This causes v a'corresponding movement. of the parts controlled by the arm 133 to bring them into the position represented in'Fig. 2 and cause the upper or black ielda of the ribbon to be brought into use. In the returnmovement of the carriage the cam face 145 on each member 143 co-acts with the roller 134 From the foregoing description it will be understood that the arm 133 is automatically shifted in one direction by a cam member 136 and is automatically shifted in the opposite direction by the cam member 143, and that said arm and theparts controlled thereby are free to, and do, remain indefinitely in either position to whlch they are moved, or until they are again shifted by the action of one of said cams to change the color fields from red to black, or Vlce versa, or until the mechanism is shifted with the aid of the hand controlled finger piece 103. It is apparent that the detent devices 104-106 tend to hold the parts against accidental displacement .from either of the two color selecting positions to which they may be moved by the cams as well as by the finger piece 103.

I preferably extend the bar 138 substantially throughout the length ofthe. carriage and provide indices thereon which correspend to those on the carriage scale 147, it

being understood that the interdental sp-aces 139 in the bar are at letter spaceintervals.

I prefer to mount the bar 138 directly overV the usual column stop bar 148 and support it-at its ends by standards 149 which are carried by the bar 148. Headed screws 150 pass through openings in the bar 138 and are threaded into the standards 149 and secure the bar to said standards. The column stop bar is in turn secured to the usual arms 151 which arev fixed to and extend rear- Wardly from the carriage.

In carrying out my present'invention I prefer to use it in connection with tabulator mechanism, so lthat as the carriage in carrying the work sheet from'one columnar field to the next, under the control of the tabulator, may automatically control the ribbon' mechanism and the characters which appear in one column, may be in black, and the characters which appear in another column may be in red, and so on.

The usual key set denominational tabulator of the No. 11 Remington machine,

r its entirety, certain features thereof unnec-V which I have shown in the present instance,

is of a character which precludes its emmodiment with certain automatically oper' ating ribbon color lshifting mechanism here` tofore devised, but by my present invention I am enabled to readily combine my mechanism to operate in conjunction with said tabulator without affecting the latter or modifying the structural features thereof.

The tabulator mechanism is not 'shown in essary for consideration in the present instance being eliminated. The eliminated parts in question relate more particularly release the carriage.

,main frame of the machine.

of each denominational stop lever- 162 is.

to the means whereby thecolumn stops are -l returned to normal position on the column stop bar and to the carriage releasing means. The tabulator mechanism as shown includes the column-stop bar 148, hereinbefore re ferred to, and on which column stopsr 152 are mounted at letter space intervals tomove arms 155 which project up from the bracket plate 131 hereinbefore referred to. A second crank arm 156 projects rearwardly from the rock shaft and is connected at its rear end to a depending link 157. The lower end of this link is pivoted at 158 to a key lever 159 fulcrumed on'the fulcrum bar 11 and provided at itsforwa'rd end with a key 160 by which the stop setting member 153 may be actuated to project the column stop 152 in register therewith to operative position'. In order to .avoid confusion in the showing this stop setting mechanism. has been eliminated in Fig. 3. A series of denominational stops 161 of the usual construction are formed by the upper ends .of a series of levers 162 pivoted at 1.63 in a tabulator frame 164 xedly secured to the The lower end pivoted to the rear end of a link 165, the forward end of each link being pivoted to thedepending'arm of an associated angular lever 166. These levers turn on-a pivot rod 167 which extends -across -the base of the machine and is secured thereto. A finger 168 at the forward end of each angular lever 166 extends through an opening in a key stem 169 provided at its upper-end with a key 170. The usual carriage releasing mechanism, not shown, is operated at each actuation of la denominational key 170 to This mechanism is the same as .that embodied lin the N o. 11 Remington` machine and further description thereof is deemed unnecessary, it being understood, of course, that a depression of a denominational key 170 is effected torelease the carriage and project the corresponding denominational stop 161 into the path of the operative column stops 152, to co-act successively therewith to arrest the carriage.

4Referring particularly to Fig. 3 it will be seen that a work sheet A is shown in place in the machine.4 Such sheets are ordinarily divided bv vertical ruled lines c, whichseparate the different columns. 'In setting the column stops 152 and the wipers or cams iso 136 and 143 the work sheet may first be introduced into the machine and the column stops set according to the different columns determined by the ruledl lines c on the work sheet. After the column stops have been setas required the'v members 136 and 143 may be set in'accordance with the positions of 'the ruled lines c on the sheet, and in accordance with the desire of the operator to write in either red or black in the different columns. In the present instance the col-1 umus are indicated on the `sheet by the charas they are toA appear in the different colappears.

umns as enumerated above, theoperator will bring the first dividing line c to the printing point and observe the p oint on lthe carriage scale 147 where such d1v1s1on line In the present instance this will appear at 60 on the carriage scale. The operator will then set a wiper 136 at 60 on'the supporting bar 138, andin a llke manner the position of each of the division lines separating the columns will be determined by successively moving the-.carriage to bring said lines c successively to thev printing point and adjusting the wipers on the bar 138 accordingly. If, as in the present instance, the columns are to be written alternately in black and red, then the wipers will be set as represented in Fig. 3 with a wiper 136 located at the point 60 on the bar 138, this point corresponding to the position of the division line c between the first and second columns on the sheet. The next wiper to the right is located at SO on the last wiper 143 to the right is for shifting to the black field, and so on these wipers may be arranged indefinitely according to the colors to be Written in the individual columns. l Just to lthe left of the left-hand In the operation of the machine the operator will proceed to write in the first column d in the usual manner, and the characters will appear in black. When the wrlting in this column ,.is completed the operator willpress the requisite denominational key 170 to bring the work sheet v in -the proper denominational [positions to' start the writing in the second column e. During this movement of the carriage the cam face 142 on the first of the wipers 136 will be brought into coperation with the roller 134 and shift the arm 133 rearwardly, thus actuatlng the intermediate trainof devices between the arm 133 and the shifting frame 81, .causing the latter to be shifted to the i right/'from the position shown in Fig. 2, and anywrlting which appears in the second column will be produced in red. After the .work in this column is completed the operator will press the requisite denominational key 170. As the carriage is moving to bring the third column f to the proper position opposite the printing point, a cam face 146 on the wiper 143 situated at .80 on the bar 138 will shift the crank armA 133 forwardly and thereby move said arm and the parts controlled thereby tothe position shown in Fig. 3 so that any writing within the third column will appear in black. And so von the fields to the printing point. It will be understood that in the return movement of the carriage from left to right the arm 133 will be shifted either backward or forward vby the cam faces 141 and 145 '-respectively, when the roller 134 is in the path of said cams. the wiper located at 60 on the bar 138 would leave the arm 133 and the parts controlled thereby in position to write in red, and writing would'appear in red in the first column where it is intended it should appear in black. It is for this reason that one of the Wipers 143 is located just to the left of the first of the wipers 136. Itwill be understood that immediately after the wiper 136 situated at the point 60v on the scale passes to the right of the roller 134 the cam face 146 on the wiper 143 just to the.

left thereof will vshift the arm 133 so that any writing which appears in the first column will be written in black. -Y

Should the operator desire to print in red in thel second, third and fourth. columns,

' for example, it is merely necessary to shift the wiper 143 situated at S0 to the dotted line position represented in Fig. 1. Said wiper would then be inoperative on thevcontrolling member 133 and saidl controlling member would not be' shifted until the last wiper 143 to the right reaches the roller 134. In a like manner any or all of the wipers may be shifted on the carrying bar 138 to the inoperative position. In this manner any individual wiper may be rendered inoperative or all of them may be rendered in- As the carriage moves to the lright 1 lio operative should it' be desired to'thriow` the automatic ribbon color shifting mechanism out of operation.

Various changes may be made without departing from the spirit and scopeof'my invention and certain features thereof may be e A employed'without others.
