MANIFOLD RECORD MACHINE Filed Dec. 5, 1951 4 Sheets-Sheet 4 INVENTOR 9min Tryyelzu'zye'z ATTORNEY MANIFOLD RECORD MACHINE John Toggenburger, Hartford, Comp, assignor to Underwood Corporation, New York, N. Y., a corporation of Delaware Application December 5, 1951, Serial No. 259,910 14 Claims. (Cl. 197-426)v This invention relates. to manifolding typewriters or printers, such as manifold billing machines, and may be considered an improvement over the patent to Davis, No. 2,204,247, dated June 11, 1940.

The machines to which this invention more particularly relates are those in which superposed sets of forms are supplied to a printing station in the'nature of continuous superposed webs or folded plies, and strips of transfer material, commonly referred to as carbon strips, are interleaved between such webs for repeat use. The printing impressions on one web are usually made by the type through the medium of a fabric ribbon pressions on the other webs are effected through the medium of the carbon strips. After each set of forms has been typed, the carbon strips are shifted lengthwise of the webs out of the typed set of forms or work-fields, and subsequently the typed set of forms are severed.

In the machine of the invention the carbon strips extend from a supply source in the nature of rolls or spools, and after the coating on the leading portions of the carbon strips becomes exhausted from repeated color transfer, a fresh portion of the carbon strip is drawn oif the supply source, said exhausted carbon strip portion being cut off and disposed of thereafter as a part ofthe procedure.

So far as the shifting of the carbon strips to register with succeding forms of the web is concerned, machines are known which accomplish this efficiently. However, the operational procedure to effect at intervals a draw-off of new carbon strip material from the supply source and to disposed of an exhausted portion, has been very complex, tedious and cumbersome. Also the usual practice has been to dispose of a length of transfer strip commensurate substantially to a full length of a writing form, even though usually only the transfer coating of. only a specific small portion, much smaller than a form length, has become exhausted of color matter. The reason for and the imttes Patent() such excess disposal has been that it makes possible a somewhat less complex procedure to draw off carbon strip. Thus in the stated usual practice much of the carbon strip is never used and thus is wasted, Wherefore it becomes more often necessary to load the machine with a new carbon strip supply.

It is a main object of the invention to provide in connection with a manifolding machine of the stated type, etlicient facilities to call into use, from time to time, a new portion or panel of carbon strip.

t f th b' t f the Invention to rovide effi- 1 I is a er 0 Jec O 1 p latch 21 normally in place over a pin'22 cient facilities to call into use, from time to time, a new portion or panel of carbon strip which in length is much smaller than the forms- Another object of the invention is to provide efiicient mechanism conveniently controllable to bring into use, expeditiously, whenever desired, a new transfer strip panel.

A more specific object of the invention is to provide a selectively variable, efficient stop mechanism for a carbon strip holder or carrier, either conditionable to measure a normal transfer strip retraction or shift out of a typed set of forms or to measure a shorter carbon strip shift preparatory to disposal of an exhausted carbon strip portion, or to measure a transfer strip pay-off of predetermined extent from the supply source.

A further object of the invention is to provide in connection with a stop mechanism which is settable to measure carbon strip pay-off, efiicient means so that when such stop mechanism is set for the stated purpose, the carbon mal position of the platen 16 bears down on usual paper feed 2. strip is: concomitantly, freed automatically to a pay off from the supply source.

It is also an objectto provide conveniently controllable, simple means whereby to control. the operations for obtaining a fresh panel of carbon and whereby to dispose of an exhausted panelof carbon.

Still other objects. and features of the invention will be apparent upon consideration of the; detailed description which follows, as the description is read in the, light of the accompanyingdrawings.

By way of example the invention hasbeen embodied in a machinewhich is of the type shown in the patent to geirsnery and Smith, No. 1,132,055, dated March 15,

Referring now more particularly to Figures 1 and 8 of the drawings, a carriage designated by the general reference character 10 is mounted in a conventional manner to travel upon a rail structure comprising a rear rail 11 supported on a main typewriter frame 12; The. carriage 10 includes an inner frame 13 comprised of opposite end plates 14, connected by a bar 15,. and carrying rotatably therebetween. a platen roll 16. The inner frame 13, for a purpose to be stated later, is supported on the carriage for pivotal displacement about pivot studs 17 provided at opposite ends of the carriage. The hotthe displaceable frame 13 is such that rolls '18. Between the side plates 14 'of' the inner frame 13 there extends a usual form severing knife. 20'. The inner earriage frame 13 is held in the'stated normal position by'a mechanism comprising at each end of the carriage a carried on the end plate 14. Said latches are fast on a shaft 21a and are spring-urged to latching position. They are releasable by operation of a finger piece- 23. In a manner fully shown and described in said patent to Wernery and Smith, the platen is adapted to be rotated by knobs 24, and line space movementsv may be imparted thereto by operation of a line space mechanism indicated by a handle 25..

superposed webs. or folded plies 30 are supplied to the platen from the rear of the latter over a structure 31 which by brackets 32 is connected with the carriage 10 to partake in its movements. The said structure 31 includes two spaced trackways 33 whereon by means of grooved rollers 35 in engagement with said trackways 33, a carbon carrier 34 is adapted to travel toward and away from the platen 16-. Said carbon carrier 34 in its main respects is substantially the same as disclosed in the patent to Smith, No. 1,979,292, dated November 6, 1934, and comprises a truck plate 36 bearing on the underside thereof the said grooved-rollers 35. Upon this truck plate there is carried a removable unit comprising a bed plate 40 having fast thereon at each lateral end thereof a carbon roll supporting bracket 41. A latch mechanism indicated at 37 holds the unit 40, 41 detachably on said truck plate. Each of the brackets 41 includes a front wall 42 and a rear wall 43. Extending fore-andaft of the machine, carried rotatably between said walls 42 and 43 of each bracket are a plurality of carbon strip supply spools 44, these spools comprising each a shaft 45, a front flange 46 and a rear flange 47, see Figures 1 and 4. To facilitate the removal of the spools 44, as for the purpose of loading rolls of carbon strip thereon, the shafts 45 have their rear ends accommodated in open notches of the walls 43, and releasable lock slides 48 keep the spool shafts 45 normally in place. The same as in the said patent to Smith, carbon strips extend from said spools 44 transversely of the form webs 30, and by being led over diagonal guides 50 extending between the I Webs from opposite sides, are given turns to extend interleaved with the webs beyond a location on the platen where impressions are received from types 51, as indicated in dot-and-dash lines in Figures 1 and 2. Each diagonal guide 50 is part of a substantially triangular rod structure which includes in flanking relation to the path of the work webs 30 a rod 53, see Figure 4, pivotally and removably supported in the walls 42, 43 of the brackets 41, in a manner and for purposes fully brought out in the stated patent to Smith. The bed plate 40 v has a usual rest 59 for the diagonal guides to rest upon.

The trackway supporting structure 31 has been stated to travel with the carriage 10. Well to the rear of the carriage the said structure 31 is guided to travel on a trackway 54 which is fast on a rearwardly reaching extension 55 of the typewriter frame 12, the said structure 31 having downreaching brackets 56 supporting rollers 57 to travel on said trackway 54.

The work Webs 30 are led to the platen 16 from the rear of the machine over a crossbar 58 of the trackwayp,

supporting-structure 31, and pass forwardly over a guide rod 60 on the carbon carrier. For support of the rod 60 the spaced brackets 41 of the carbon carrier 34 have each a rearwardly reaching arm 61. Side edge guides 62 on the rod 60 confine the work webs 30 laterally in their approach to the platen 10. The triangular structures 50, 53 lead carbon strips 63 supplied from rolls 64 on the spools 44, in alternate order, between the work webs 30 from the opposite sides thereof. In Figure 4, only two carbon rolls 64 are shown in use, although the machine is built to accommodate at least four such rolls, see Figures 3 and 5.

The several spools 44, and therefore the carbon rolls 64 thereon, are in the normal operation of the machine locked against turning. To this end the front flange 46 of each carbon roll spool has serrations 72 with which there is in engagement a detent pawl 73. The latter are pivotally carried as at 74 on cars of the front wall 42 of the carbon roll bracket 41. Said pawls are under clgnstant tension of springs 75 to engage in the serrations Assuming a last typed form has just been severed at the knife 20, as is the condition shown in Figure 2, the set of forms in position around the platen 10 is typed upon in a conventional manner. In most work, as in billing, typing may end well in the upper portion of the form. After typing has ended, the platen, facilitated by the pivotally mounted inner frame 13, is displaced to the position seen in Figure 6, wherein said inner frame 13 comes to rest on an abutment 65 provided on the V carriage. operator and drawn forward to a gage 66 which is supported on a bar 67 constituting a unitary part with the pivoted inner frame 13. While the work webs 30 are held at their leading ends against the bar 67, the carbon strips 63 are then retracted from the just typed set of forms or work-fields by movement of the carbon carrier 34 rearwardly to a position wherein an abutment 68 on the carbon carrier engages a stop 70 on one of the The work webs 30 are then grasped by the trackways 33 for the carbon carrier. It will be observed that due to the displacement of the platen 16 to upper position the carbon strips are retractable rearwardly in the work webs 30 in a straightened out condition, Wherefore there is a minimum of frictional contact between the carbon strips and the work webs. The stop 70 is adjustably mounted on its supporting trackway 33 and is given a position relative to the abutment 68 so that the leading ends of the carbon strips at the end of the retracting movement of the carrier will be stationed at short distance rearwardly of the work web severing knife 20. While the operator still holds the leading ends of the webs 30, the platen is then restored to normal position and the typed set of work forms is torn off, and the next set of forms to be typed upon is then in position. During the restoration of the platen 16 to typing position the carbon carrier is drawn idly forwardly away from the stop 70 inasmuch as in this operation the work webs and carbon strips are tucked downwardly in a bend into the carriage. The stated procedure is repeated for typing a number of successive forms and when the coating of carbon on the leading portion of the carbon strips 63 becomes weak it becomes necessary to draw off a new section or panel of carbon strip from the strip supply. It is the principal feature of the invention to accomplish this efiiciently. Subsequent to the completion of typing a set of forms, whenever it is desired to obtain new panels of carbon strips, the platen is displayed to the position seen in Figure 6, and the carrier 34 is retracted an abnormal, shorter distance to the extent illustrated in Figure 7. To accomplish this conveniently and expeditiously the invention provides for a placement of an abutment 80 into cooperative relation with the carbon carrier stop 70, the abutments 80 and 68, along with a still further abutment 81, being provided on a member 82 which is movable laterally on the bed plate 40 of the carbon carrier 34. Normally, as seen in Figure 5, only the abutment 68 is in alignment with the stop 70. When the stated shorter carbon retraction is required in accordance with Figure 7, then the member 82 is preparatorily shifted leftwardly to place the abutment 80 into cooperative relationship with the stop 70. The manner of positioning the member 82 to place the abutments 80 or 81 into cooperative relationship with the stop 70 will later be described.

Following the positioning of the carbon carrier 34 in accordance with Figure 7, the platen 16 is restored to normal position while the front ends of the webs are held in position against the leading form gage 66. Because the platen, in being restored, tucks the work webs 30 and the carbon strips 63 down, the carbon carrier 34 travels a short distance forward away from the stop 70, as in Figure 8. At this point in the procedure the member 82 is shifted laterally to bring the abutment 81 into alignment with the stop 70 and furthermore the detent pawls 73 for the carbon strip spools 44 are released. This having been done, the carbon carrier 34 is moved rearwardly an additional distance to the limit provided by the abutment 81 engaging the stop 70. During this additional movement of the carbon carrier 34, the front ends of the carbon strips remain stationary inasmuch as the spool detents 73 are released and the carbon strips 63 will pay off freely from the carbon rolls to the diagonal guides 50 and forwardly thereof. In this movement of the carbon carrier the work webs 30 and the carbon strips are resisted against rearward movement by their being pinched between the platen 16 and the feed rolls. The member 82 and the spool detents 73 may then be permitted to restore to their normal positions in a manner which will become evident later. The leading set of forms is then severed at the knife 20 and it will be observed that along therewith there will be torn off a small leading panel or portion of the several carbon strips 63. The next set of forms is then typed upon in the regular manner, and when thereafter the carbon strips 63 are retracted to the extent limited by cooperation of the abutment 68 with the stop 70, their fresh leading ends will then be in a position beyond the rear of the cutting edge of the knife 20 by an extent which corresponds to the difference in the relative locations of the abutments 80 and 81.

As is especially evident from Figures 1, 3 and 5, the abutment member 82, together with an elongate member 86 reaching from one to the other side of the carbon carrier comprises a unit which is slidably mounted on the carbon carrier 34 for lateral movement in opposite directions from its normal position seen in said figures. To the end of slidably mounting said unit 82, 86, the member 82 thereof, at the location of the abutment 68, has a downward offset facing the rear edge of the bed plate 40, and the elongate member 86 is closely contiguous to the front wall 42 of the left carbon roll suplatter rightwardly in closely overlying relation with the member 82 keep the latter confined to slide on the 'bed plate '40. At the left the elongated member. 86 is slidably guided on the front wall 42 'of the bracket 41 thereat, the wall 42 having ashouldered screw -90'whereon said member 86 is slidable by 'provision of a slot 88. The said unit 82, '86, under the influence of :a spring device 91, is constantly urged to assume the middle position seen in Figures 1, .3, 5, said "spring device :91 'being supported on the bed plate 40 and having fingers 92 bearing-with tension toward each other oppositely .against a nose 99 see Figures 1 'andx3, to the limitprovidedby a pin '93 on the bed plate 40.

As has been stated hereinbefore, the :carbon spool detent pawls 73 are normally active, and having reference 'to Figures 1 and 3 it will be noted that if the 'elon- :gate member 86 is in central position,upreaching fingers '94 on such memberwillbe disposed aha-slightdistance to the left of forwardly reaching arms *95 of the 'detent pawls 73. When "the elongate'member86 is'moved leftwardly to bring the abutment 80 into 'alhgment with the stop 70, then the said fingers 94 move idly further away from the pawl arms '95. However, the elongate member 86 is moved 'to the right of its "normal position to place the abutment "81 into alignment with the stop '70,, then the 'upreaching -fingers 94 will contact and displace all the pawl arms 95 rightwardly, releasing all the p'awls 73 and freeing all the carbon spools for carbon strip pay-off action.

The movement of the'slide unit8'2, 86T1S conveniently accomplishable from the front of the-machine byracontrol device generally designated bythe reference numeral 96, which control device also serves as a convenient The saidtubular arm 97 ends 'at the rear in a 'pin 98 which is pivotally accommodated 'in a boss 1 of a bracket 101, thelatter having 'a base port'i'on ,10'2 reaching under and fastened to theunderside of the truckplate 36 by screws 103. The tubular arm terminates atthe front in a handle 104 which stands normally upright as shown infull lines in Figures '1 and .3. Fast on and reaching downwardly from the rear end of the pivot pin 98 there is an arm 105 which has a'lower, thickened portion 105a situated between two protuberances 106 in "the elongate member 86. The thickened arm portion 105a -is 'V- shaped at the bottom and cooperates there with an upwardly spring-pressed, pivoted arm 107 ihaving a V- shaped notch 108 to detent normally the arm,105 in a position for the handle 104 to stand vertically. The

said arm 107 is pivotally borne on a bracket I that is secured to the underside of the truck plate '36. .A .flat spring leaf 111 is secured at and extends from ,underthe bracket branch 102 forwardly 'to bear resiliently upwardly 0n the arm 107. The latter has anotch at .112

'whereinto there reaches normally an ear 1113 of the elongate slide member .86, thereby locking the latter normally against lateral movement. This insures that the slide unit 82, 86 will not .move laterally by power of momentum when the carriage .10 .is abruptly set inmotion or stopped. When the unit 82, 86 needs .tohemoved leftwardly to place the abutment 80 into'alignment with the stop 70 then the operator is required .to give :the handle 104 a clockwise .movement. From "Figuresjand 5 it will be seen that the two protuberances 106 stand normally a slight distance laterally from the thickened arm end 105a. When the handle 104 is .g'ivensaid clockwise movement the first ,elfect will'be the camming down of the arm 107 by the arm end 105a riding :out of the notch 108. This frees the protuberance 113 of .theelongate member 86 from the notch 112. Upon further clockwise movement of the handle 104 the mm .105 engages the protuberance 106 to its left and there results .a leftward displacement of the member 86 .to .the extent permitted by the slot 88. This places the abutment 80 into cooperative alignment in front of the .stop .70. If thehandle 104 .is givenan-ant'bclockwise movement, :the arm 107 will first be cammed down to {free the member 86 at the ear 113. Then the member 86 is picked up by the arm .105 encountering the protuberance 106 at its right, and is displaced rightwardly to the limit permitted by the slot 88. This will place the abutment 81 into cooperative relationship with-the :stop .70 :and tat 6 same time *by reason of engagement of the -lingers 94 with the detent arms 95, all the detents 73 are released from the carbon spool flanges '72.

Whether the handle 104 :is turned clockwise or anticlockwise, it and the unit 82, 86 will readily reassume 'normal positions as soon as the handle is released, it being remembered that the elongate member 86 is under the constant urge of the spring device 91 to return to 'normal, central position, :and it being evident that as it assumessuch-position the :detent arm 107 at the V-notch acts-to centralize the am 105, and thus the handle So far as the shift of the carbon strips '63 from the successively leading form sets of forms or work-fields is concerned, the operator, after displacing leading edges :of the webs30 to the gage:66, merely pushes the handle 104 rearwardly .to -.the limit provided by the abutment 68 in cooperation with the stop 7-0. Upon restoration of the platen .to typing position and tearing off of the leading set of formsor work fields of 'the:webs, the machine :is readyfor'typing the :next se'tof forms.

The procedure to be followed from time to time to bring fresh portions of the carbon strips 63 into transfer position will now be briefly described. First, after typing on a set of forms has been completed, the operator displaces the platen and brings the leading ends of the webs 30 against the gage .66, the carbon strips moving along with the webs. Thereupon the operator turns the handle .104 clockwise about the axis-of the pin 98 and then pushes the same rearwardly. Since the clockwise turning of the handle 104'places the abutment -into line with the stop '70, it follows that the carbon carrier 34 will be retracted only to the shortened extent allowed thereby, namely to the Figure 7 position. This places the leading ends of the carbon strips 63 a-s'hort distance in front of the cutting edge of the knife 20, such distance being commensurate with the portions of the-carbon strips which subsequently in the procedure will be cut off. There- 'upon th'eoperator restores the platen towvriting position and as illustrated in Figure .8, the carbon carrier, due to the webs and carbon strips being-tucked down by the platen 10, is drawn forwardly a short distance. The operator then turns the handle 94 in anti-clockwise-direction which will have -the effect of placing the abutment -81 into line with the stop 70 and at the-same time-through movement of the fingers 94 will cause the re'lease'of all the spool 'detents 73. This is followed 'by pushing the handle 104 rearwardly as in Figure 9. In this action the leading ends of the forms are still held by the operator. Inasmuch-as the forms 30 and carbon strips 63 are resisted against rearward movement in the carriage, and said :carb'on spools are free to turn, each of the latter will pay off carbon strip past its related diagonal guide 50 to the extent of the movement of the carrier 34 rearwardly. The operator then releases the handle 104, and the abutment member 80, as well as the detents 73, reassumes its normal position. At this point the operator severs the set of leading forms at the knife 20, along with the short portions-of the carbon strips 63 which in Figure 9 extend above the knife 20. The machine is now in readiness for typing on the new leading set of forms. When typing is completed on such new forms, the platen is displaced as usual andcare is taken to move the leading ends of the webs 30 at'the gage '66 and to-hold them there while the carbon carrier is simply pushed rearwardly by the handle 104 to "the normal limit provided by the abutment 6S in cooperation with the stop 70. The carbon shifting movement accomplished thereby 'is of slightly shorter extent than a normal carbon s'hiftingmovement. This will place the leading ends of "the carbon strips 63 a short distance to the rear of the cutting edge of-the knife, to the'same location in respect 'to the knife 20 as in a normal shift of the carbon strips. When then the platen is lowered to normal position and'the leading 'setof forms is torn ofi, the machine in all respects is in a normal condition for writing and the leading ends of the carbon strips .63, asseen'in Figure '2, trail theleading ends of the webs a small, normal distance, as'zis desirable to facilitate the gripping 'of'thewebs without the carbon strips in normal carbon astrip shifts.

'It should be realized "that "in the described procedure for obtaining-.a-zfresh carbon strip :pan'el :or portion, the :several 'nperations involving .the ;handle 104 may be --;effeoted sin ;a continuous rflow. Consequently tthe rearrying out of the procedure is very convenient and takes a minimum of time and effort. 'lhe only thing the operator has to remember in connection with this procedure is that the carrier must first be moved rearwardly with the handle turned clockwise, and that after the restoration of the platen to normal position the carrier must be further pushed rearwardly with the handle turned anti-clockwise.

Obviously the abutments 68, 80 and 81 may have relatively different dispositions to provide for any desired length of carbon strip pay-off from the supply source. Moreover, the carbon strip supply may be in other than roll form and not necessarily in flanking relation to the work webs.

In certain work wherein the work forms receive impressions on a major part thereof, the partial carbon shifting operation as represented by Figure 7, as also the platen restoring operation represented in Figure 8, may advantageously be eliminated entirely. Consequently there is no need to provide the abutment 80 and to provide for the selection thereof. Under the stated circumstances the procedure for obtaining new carbon panel is considerably simplified. As a first step the operator, at the end of typing on a set of forms, simply advances the work webs 30 to meet the gage 66. The handle 104 is then turned anti-clockwise to select the stop abutment 81 and to condition the carbon supply for pay-off action. This is followed by a shift of the carbon carrier 34 rearwardly to draw off carbon strip lengths slightly shorter than the form lengths.

Of course the carbon strip shifting procedure described in the preceding paragraph may also be used if wastage of carbon strip material is of minor consideration in the particular application.

It is to be understood that while the invention has been illustrated and described only in connection with a particular form of manifolding machine, it is applicable also to other forms of such machines, either in part or in full.
