TYPEWRI'IING MACHINE.

Application filed September 13, 1924. Serial No. 737,447.

This invention relates to improvements in mechanism for positioning an interposed inkribbon with respect to the printing line of a typewriting machine, and relatively to the main or vibratory ink-ribbon.

'llhere is provided a simple, linexpensive and highly efficient controlling device for the auxiliary ink-ribbon. Certain features herein shown are described in my co-pending application filed July 25, 1924, Serial No. 728,073 (now Patent No. 1,624,697, dated April 12, 1927) The means described in said application is directed-towards locating a stretch of the auxiliary ribbon so that when it is not positioned at the printing line it is located above the printing line; the stretch of auxiliary ink-ribbon being arranged ina two portions, both horizontal but spaced apart vertically, one portion being located at the printing line, and the other portion thereabove.

lt is intended by the present inventionto improve upon the means for offsetting the interposed or auxiliary ribbon, so that, the offsetting of the ribbon is accomplished by devices at the end of the carriage, and does `not necessitate movement of the hand of the operator longitudinally of the platen.

Another feature of the present invention is the provision of means for simultaneously actuating the mechanism for line-spacing the platen and also theauxiliary ink-ribbon, the

offsetting of which latter occurs through the agency of a guide-plate which is shiftable to dispose the two portions of the ribbon in the manner hereinbefore described.

A further feature of this invention is the provision of. means. controlled by the operation of the line-spacing mechanism, for shifting the auxiliary ribbon from the printing line to a position away therefrom. However, should it be desired to permanently retain the auxiliary ink-ribbon in ineffective position so as to employ only the main ink-ribbon to produce typed impressions upon the work-sheet, it can be done Without operating the means actuating the guide-plate. On the other hand, it may be found desirable to retain this auxiliary ink-ribbon at the printing line for conjoint use with the main ink-ribbon, so as to print upon two work-sheets, line. by line, without interrupt-ion; in this event the operating handle is latched automatically after `locate it at the printing line.

being moved to shift the auxiliary ribbon to Thereupon, the typist positions a detent mounted upon the latch in ineffective position to be engaged by the spacer-slide of theline-spacing mechanism at any time through the operation of the latter. As a result, the latch is not disengaged from the handle by means of the spacer-slide, as is contemplated where the work-sheets take the form of a check and record sheet respectively, so that the handle is still held in operative position and the auxiliary ink-ribbon is still retained at the printing line. When the latch is released automatically by the line-spacer-slide, the operating handle is automatically restored to normal position by means of a spring, and this action, through suitable connections, will cause the auxiliary ink-ribbon to return to ineffective position.

Owing to the co-action between the linespacing of the work-sheets vand the shifting of the auxiliary ink-ribbon to ineffective position, it becomes necessary to provide for progressively removingbne check and inserting another check upon the upper shelf and in engagement with the platen, because some of the lines typed upon 'each check will be duplicated through the auxiliary ink-ribbon upon the permanent record-sheet, while other lines need only he typed by means of the main ink-ribbon alone upon the check only. In removing the check it isdesired to -hold the record-sheet against movement or creeping relatively to the platen, but this would be impossible owing to the casting-off of the feedrolls holding the check and record-sheet on the platemwere it' not for the fact that another set of pressure rolls are provided to clamp down ,under tension the work-sheet at the top of the platen. In order to permit the record-sheet to be replaced after casting-off the usual feed-rolls, it is also necessary to disengage the pressure-rolls, which press this sheet Onto the top of the' platen. Manuallycontrolled mechanism is provided for doing this, which mechanism is controlled by a handle and serves to lift these pressure-rolls out of contact with the platen, thus providing clearance for the removal of the record-sheet.

At the same time this action of casting-off the auxiliary-pressure-rolls takes place, the guide-plate, which serves to shift the auxiliary ribbon towards and from the printing line, is pushed away from the platen, so as to provide clearance at this point, and so as to facilitate the insertion or removal of a record-sheet.

Another feature of the present invention is the provision of mea-ns for causing the usual tween the operating handle and( the guideplate, thus causing this guide-plate to travel a comparatively long distance when a relatively short movement is imparted to the operating handle.

It will be understood, that the present invention is particularly designed for use in connection with typewriting upon the check in a manner where it is intended to type a number of lines on this check and to transfer certain of these lines onto a permanent recordsheet. This record-sheet receives seriatim certain data being usually the name of a person and the amount of the check drawn in favor of this person, the idea being to type upon this record-sheet the aggregate number of amounts drawn upon in favor of different payees listed on different checks. But inasmuch, as each check is t ped upon at other points which produces ata, which it is not desired to transfer onto the record-sheet, it becomes necessary to prevent the recordsheets from being typed upon during the action of the type-bars against the main inkribbon,.hence the present invention vhas been brought about to provide for this occurrence in typewriting practice.

Other features and advantages will hereinafter appear.

Figures 9 and 10 are views partly in section showing the latch-bar in inoperative and operative position, respectively, and associat- In the drawings which are merely illustrative of the present invention 1() designates the usual type-bars having the type-surfaces 11 which are caused to impinge upon the main ink-ribbon 12. The usual feed-rolls 13 and 14 apply tension against the under side of the platen 15 mounted on the shaft 16 which is rotatable by the finger-knobs 17. This platen 15 overlies the apron 18 of the usual papershelf 19 suitably secured to the end supports 20 of the platen frame, a ratchet-wheel 21 being operatively connected to the shaft 16for line-spacing the platen. End plates 22 are engaged upon the supports 20.

Guide-members 23 are located fixedly adjacent the opposite ends of the platen and have oppositely-inclined diagonal slots 24 in which are movably guided an auxiliary ink-ribbon 25 which is guided over rollers 26 mounted upon the guide-members 23, the latter serving to divert the horizontal movement of the auxiliary ribbon 25 to a vertical movement, which last-named movement is impressed upon lits stretches 29b and 29, the guide-members 23 being secured -by'brackets 30 upon the supports 20.

Ribbon-spools 31 are positioned at the rear of the guide-members 23 and in line therewith over which the ribbon stretches 2()b and 29c are trained after leavin the rollers 26. A supporting bar 32 exten s longitudinally in front of the platen above the printing line and terminates in right-angularly disposed arms 34, shown in Figure 3, which are fulcrumed so as to pivotally support the reduced ends 33 of said bar, as shown in Figure 6.

The .arms 34 have depending lugs 35 held by the springs 36 secured upon the pins 37 mounted in the brackets 30. Secured longitudinally in back'of the bar 32 is a rail, track or stri 38 which has its opposite ends 39 secured y fasteners 44 to the bar 32. A

ratchet-wheel 40 is secured upon each ribbon-` spool 31 for the purpose of rotating the same, each spool being journaled upon a shaft 41 mounted in a bracket 30a (Figure 5), a suitable spring-brake 42 surrounding the shaft 41 and applying pressure against theside of the spool induced by the thumb screw 43.

Suitable line-spacing mechanism, well known to those skilled in the art, is provided for engaging the ratchet-wheel 21 of the platen shaft 16 for the purpose of rotating the platen 5 and includes the usual linespacer slide 45. Arranged to slidably engage the track 38 is a sleeve or collar 46 which is formed integrally with a guide-plate 47 havof the diagonal slots serving to offset in Zigzag fashion the auxiliary ribbon to provide operatively-extending horizontally-disposed i stretches 27 and 28 which are vertically spaced apart so as to position one stretch at thev printing line and the other stretch one line above the printing line. V

llt will be seen that the guide-plate may occupy an extreme right or left positionon the carriage. f'it is located at the extreme left end of the platen, as shown in Figure 7, the auxiliary ink-ribbon will extend practically the entire length of the platen above the printing line indicated at E on the check B in Figure 7. Should it be located at the extreme right of the platen the elfect will be to position the auxiliary ribbon longitudinally of the platen directly at the printing line, as shown in Figure 6.

A paWl 50 is mounted on the pivot`pin51 carried by a lever 52 having ahandle 53, the pin being supported upon a lever 54. the tree end of which is offset at 54n and projects in the path of movement of an operating handle 75 about to be described. This lever 54 is fulcrum-ed on a screw 55 threaded into the bracket 56, a spring 61 secured to a pin 62 serving to hold the lever 54 against the pin 62 to position the free end oi" the lever 54 relatively to the operating handle 75;l

another spring 57 is secured relatively to a pin 58 on the lever 54 and on the pin 59 on the pawl 50 and exerts a pull that tends to main ytain this pawl in engagement with the ratchet-Wheel 40.

The collar or sleeve 46 ot the guide-plate 47 is provided with a stud 64 to which is sen cured the opposite ends of a cable or belt 65 p which is trained upon pulleys or drums 67 and 68, the pulley 68 being ixed upon a stud shaft 69 mounted upon the standard 77 secured to the platen frame, while a journal for the pulley 67 is mounted upon a bracket arm 111 at the right end of the machine. A pinion' 70 is fixed upon the shaft 69 for driving the pulley 68 and this lpinion meshes with a gear 71 journaled at 72 upon the standard 77. Fast upon the shaft 72 so as to rotate with .the latter is a smaller gea-r 73 which meshes withaseotor gear 74 formed with an operating lever 75 having the handle 75a A pin 78 is fixedly secured upon the standard 77 which serves to provide a stop for the operating handle lever 75, A suitable spring 115 is secured at one end upon the standard 77 and is secured at its opposite end upon the sector gear 74 and serves to thus normally press the operating handle lever 75 against the. stop pin 78.

The llever 7 5 is constrained to travel in the path of movement of a latch bar 81 fulcrumed upon a screw 85 ,threaded into the bracket 30 and having 'a latch hook 80 provided with the finger-piece .82 by means of which it may be retracted. A spring 83 is secured to the latch bar 81 in order to hold the latter pressed with its shoulder 83a against the stop pin 90,'a't Whichtime it will be seen that the latch bar 81 inclines in operative position effective to latch'the handle lever 75 after the latter has been caused to snap thereunder. A pin 91a is mounted upon the end of a flat detent spring 81, secured to the face of the latch bar 81, and extends through a hole 91 in bar 81. An arm or detent 86 is fulcrumed upon-the screw 85 and a pin 87 serves, when the arm or detent has been moved down uponl its screw 85, to engage the notch or recess 89 formed upon the lower end ot' the latch bar 81, below the screw 85, and, in this manner, the pin 87 is limited in movement in the notch, and the terminal lip 88 of the detent is positioned so as to project forwardly to position for actuation by the slide 45.

The arm or detent 86 is provided for the purpose of actuating the latch bar 81 to retracted position relatively to the operating path of the slide 45. l/Vhen in such inop- 'erative position the pin 91a snaps into a recess 84 in the detent 86.. l

For the purpose of permitting the recordsheet A to be held in proper undisturbed relationship upon the platen 15 while the feed rolls 13 and 14 are being cast-oli to release the check B from engagement with the platen, auxiliary pressure rolls are provided to press the record-sheet down upon the upper surface of the platen. Upon a pivot `pin 95, located as shown in Figure 3, is "fulcrumed a lever 96 having an operating handle 97. This lever 96` is formed with a recess 98 between its ends and arranged to be received and' held in this-recess is a shatt99 which extends longitudinally ot the platen and is supported operatively upon a longitudinally extending series of separated lever arms 100 which are fulcrumed upon a rod or shaft 102, as shown in Figure'. The pressure rolls 101 are rovico arms 100 to assure that all the pressure rolls 101 will bear down with 'suliicient tension upon the top of the platen so as to engage and overlie the record-sheet A.

The springs-103 are secured upon the pins 104 secured upon the platen frame and also upon the pins 105 secured directly upon the arms 100. The lever 96 is also formed with a cam 106 in a plane with the recess 98, this cam being normally/.located so as to extend just beneath the shaft 99. Adjacent the cam and in alignment therewith is the bar 32 which supports the guide-plate 47. 110 designatesy the usual stop which is secured at any desirable point along the length of the bar 32 to position the adjacent longitudinal edge of the work-sheets thereat. As shown in Figure 6, this stop or rest 110 is located so as to position the work-sheets and especially the removable check B at a point where it is spaced from the adjacent end of the platen. However, it could be located at a point where it would be in vertical alignment with the guide-plate when the latter is located in the extreme left end of the platen, as shown clearly in Figure 7. In this latter posit-ion, it will be seen that the check will be permitted to extend with its left edge overlying the guide-plate 47, and the distance of traverse allowed the guide-plate 47 towards the right end of the platen will be regulated so that it will come to rest with the right edge of the check overlying it. The reason for doing this is to avoid collision of the auxiliary ribbon-guide with the side edges of the check which may occur by shifting the ribbon-guide from a position beyond the edge of the check to render the auxiliary ribbon ineffective. The bracket arm 111 supporting the pulley 67 is secured bythe plate 112 upon the end support 20, the fasteners 113 holdingy this plate in position.

The operation of the present invention will now be detailed. The typist irst of all inserts the record-sheet in position to engage the platen. A check B is next inserted in position so as to be interleaved between the main ink-ribbon 12 and the auxiliary ink-ribbon 25; it is proposed to type upon the check line C to write in the name of the payee of the y check as well as the amount to be paid him;

and also in the next succeeding line D to write in, unabbreviated, the full amount of the check opposite the printed legend Dollars. Of course for permanent record purposes it would be mere repetition to reproduce both lines C and D upon the record sheet, therefore it is intended only to transfer line C of each check upon the record-sheet so that the latter will contain a permanent record seriatim of all the payeesl of the several checks successively typed upon together with the` amounts drawn upon against the payors of these checks in favor of the payees. It becomes necessary to position the auxiliary inkribbon directly at the printingline of the machine to make it align with the main inkribbon in order to assure that when line C is typed upon the check through the medium of the main ink-ribbon the typed impressions thus produced will be simultaneously reproduced or transferred through-the auxiliary ink-ribbon upon the record-sheet A.

When the parts of thepresent device are in normal position the guide-plate will be located at the extreme left end of the platen. In order to position the auxiliary ink-ribbon at the printing line, it must be moved downwardly as it is disposed just one line above the printing line, but still in the printing zone when the guide-plate 47 occupies the extreme left end position shown in Figure 7.

The typist grasps hold of the operating handle and pulls the same downwardly until lever 54 and forces the same downwardly.

against the tension of the spring 61, and as the lever 54 moves downwardly so does the pawl 50 which thus actuates the ratchet-wheel 40, thus rotating the spools 31 and feeding along the auxiliary ink-ribbon, so that a fresh surface of this ribbon will be advanced longitudinally of the printing line.

As the operating handle 75, has moved downwardly to latched position, the sectorgear 74 turns and rotates the small gear or pinion 78 which also rotates the larger gear 71 which meshes with the small gear or pinion 70, thereby rotating the pulley or sheave 68, thus setting in motion the cable 65 and drawing along the lower stretch thereof in a direction toward the right end of the machine, and as this stretch is secured to the stud 64 of the guide-plate 47 the latter is caused tol move away from its normal position at the left of the machine, and because of the gear multiplying power one actuation of the operating handle 75 serves to turn the gears a sufficient distance to project the guideplate 47 the distance shown in Figure 6 where it comes to rest at a point where the right edge of the check B will overlie it at its median line. The ribbon' is now at the printing line.

Where, as in Figure 6, the stop is located at a point spaced in advance of the .position occupied by the guide-plate 47 when in the normal position shown in Figure 7 the manner of inserting the check in proper relationship with the platen will be as follows Inv order to avoid spoiling the edge of the check by the forcible contact made therewith by the guide-plate edge in the act of the latter beginning its traverse toward the right end of the platen, the check need not be inserted until after the guide-plate has been moved to its qualified position' shown in Figure 6, when the auxiliary ink-ribbon has been located at the printing line. The stop 110 might, however, advantageously be positioned at a point where it will lie midway the width of the guide-plate, thus, making it certain that, when it begins its movement as well as ends its traverse, the guide-plate will not engage either edge of the check.

The first line of the check is now typed as indicated in Figures 6 and 7 which will be also simultaneously typed upon the recordsheet; the next line need not be reproduced bar 81 with the result that the latch-bar isv tilted or rocked by the tripping action of the slide thereby causing its upper hook 80 to be disengaged and released from holding engagement with the handle 75 which being free is urged back to normal position under influence of the spring 115 and as it thus is thrust back to its normal upright position the gearing is again operated. The pulleys 67 and 68 turn and the cable 65 shifts the guide-plate 47 from the right end position to the left so that lthe auxiliary ink-ribbon 2.5 is pulled upwardly one line above the printing lline. When now the second line is typed upon the check, the main ink-ribbon 12 alone will be presented against the typevbars se that the auxiliary ribbon will not serve to transfer the typed impressions made on the check onto the permanent recordi slieet A. Figure 7 illustrates the fact that only the check will be typed upon to produce the second typed line as it appears that the auxiliary ribbon 25 is spaced above the printl ing line. It also appears from a comparison made with Figure 6 that both the check and the work-sheet A have been line spaced atthe same time to assure that the same line will not be typed upon again; that the auxiliary ink-ribbon 25 has at: the same.I time been pulled upwardly so as` to allow the type-bars t to print only upon the check.

The check may now be removed and another check inserted to be typed upon in a i Imanner already described. Before removing the check it must be ascertained whether the record-sheet A is to be removed also, which need be done only if the last line has been typed thereupon at the bottom of this sheet. Should the record-sheet remain in the machine, the check is removed while the auxiliary pressure rolls engage the record-sheet at the upper end of the platen, as illustrated raising the pressure rollers 101 out of contact and engagement with the upper part 0f the platen. At the same time thecam is acting to lift the rod 99, it is being urged in the direction of the aligning bar 32, and it is designed that at the moment that this cam engages this bar to swing it outwardly of the platen to provide clearance between the guide-plate 47 and the platen, lthe recess 98 of the lever 96 will come immediately under the shaft-or rod 99 and the springs 103 will thereupon draw the rod 99 into this recess thereby latching the rod and separating the series of rollers 101 from contact with the platen and providing clearance between these rollers and the platen at this point. The record-sheet and check may now be quickly removed from the platen after casting 0H the feed-rollers 101. This isillustrated in Figure 8. It will be seen that when the lever 96 is shifted rearwardly it will temporarily be unlatched from the rod 99 allowing the cam 106 to again engage the rod 99 and as thellever 96 recedes the rod is allowed to come down until therollers 101 again engage the platen to hold the new record-sheet and check., i"

Should it be desired to permanently make carbon or duplicate copies on the record sheet of all the matter typed upon one worksheet (which may be check, b1ll,.etc.),lit is necessary then to retain the auxiliary inkribbon at the printing line. In order not to shift the auxiliary ink-ribbon away from the printing` line each time the line-spacing mechanism is operated to rotate the platen for line-spacing purposes, the typist will take vhold of the detent 86 and lift the same and will laterally strain this detent to allow its pin 84 to enter the hole 91 formed' 'upon upwardly to the position shownv in Figure 10 the latch-bar 81 so that the detent will thus be releasably held in ineffective position; so

that whenever the line-spacer slide 45 makesl its forward thrust it will notco1lide with the trip detent 86. The latch-bar 81 will thus be ineffective to unlatch the operating `handle 75; in this waythe position of the auxiliary ink-'ribbon at the disturbed.

It may also be desirable to retain the auxiliary ink-ribbon in ineffective position one line above the printing line. In thisevent the guide-plate will remain stationary at the left end of the platen; as shown in Figure 7 printing line y will not loe;

The typist will not actuate the operating handle 75. The guide-plate supports the auxiliary ink-ribbon between its ends, so that A should the platen be rotated reversely to retract the work-sheets or for any other reason, it is assured that the auxiliary ink-ribbon will not be carried along with the platen and thus be injured. v

From the foregoing, it will be seen that a simple and inexpensive contrivance for shift- 'whereby said handle may `tendin therewith, a ribbon-guide movable along the` ing the auxiliary ink-ribbon is obtained by the parts illustrated in the drawings by which the action of positioning the auxiliary inkribbon at the printing line is manually controlled, so that the typist can reproduce at will, on a record sheet, any of the lines typed upon the check. It will be further seen that the restoration of the ribbon to ineffective position is rendered automatic, so as not to require any attention on the part of the typist, this action being controlled through and by the line-spacing mechanism, and that auxiliary pressure-rollers are provided for assisting in maintaining the work-sheets in contact with the-platen singly or collectively as well as to allow for singly or collectively removingthem from engagement with the platen. aria'tions may be resorted to within the scope of the invention, and portions of the im'- provement's-may be used without others.
