Y. Application September 25, 1933, Serial No. 690,788 '5 Claims. (Cl. 197-126) It is the object of this invention to provide a manifolding device for typewriting machines which permits of using one or more carbons repeatedly for manifolding purposes between suc- 5 cessive sections of continuous record sheets without removing the same from the record sheets afterbeing once assembled therewith, and to so construct said device that the same can be readily applied to and removed from a typewrit- 10 mg machine, also easily and ,conveniently operated and also is of simple construction, low in cost and not liable to get out of order.

In the following description similar characters of reference indicatelike parts in the several 5 1flgures of the drawings:

The typewriting machine which is shown in the drawings is typical of one suitable for use in connection with my invention, and as there shown the same comprises a main frame ID, a 5' carriage II which is movable horizontally and transversely on the main frame, a cylindrical platen I! which is mounted horizontally and transversely on the front part of the carriage, front and rear lower guide rollers l3 and II v arranged adjacent to the front and rear parts of the platen adjacent to the underside of the same for holding the record sheets or leaves l5 and the manifolding carbon sheets I6 which are intercalated therewith against the platen, and

front and rear supporting bars l1, l8 forming 5 part of the carriage.

Means are provided for retracting the guide rollers l3, l4 from theplaten l2 so as to permit of the ready introduction of the sheets or leaves of paper which are adapted to receive the rec- 10 0rd and carbon manifold sheets which are interleaved between the same, and then releasing these guide rollers l3, M in order to permit the same to press the intercalated record and carbon sheets against the platen so that upon' rotating the latter the several record and carbon sheets will be moved forwardly or backwardly and present the desired surface of these sheets to the printing line, which in this particular typewriter is located on the front side of the platen.

Inasmuch as the means whereby the carriage is moved step by step across the machine, the platen is turned either forwardly or backwardly and the guide rollers l3, H are moved either toward or from the lower part of the platen, are all of well-known and standard construction, a detailed description of the same is unnecessary.

The manifolding device containing my improvements is constructed as follows:

In its general organization this manifolding 3 device comprises aframe which-in the preferred construction is detachably mounted on the upper part of the carriage andabove the platen, andclamping means mounted on this frame and adapted to either grip the opposite side edges of the carbon sheets and permit the record sheets to be moved lengthwise of the carbons independently of the latter, or to release the carbons and permit the same to move lengthwise with the record sheets. For the purpose of utilizing the 40 present manifolding device the carbon manifolding sheets are wider than the record sheets and, when assembling the same, these carbon sheets are intercalated with the record sheets so that the opposite longitudinal side edge portions or edges of the carbon sheets project laterally beyond the longitudinal side edge portions oredges of the record sheets, as shown in Figs. 1, 4, 6 and 'l. s

. Although the drawings and the following description show and refer more particularly to the use of a plurality of carbon sheets which are alternated with a plurality of record sheets in the assembly of .a section or set of such sheets,

it is to be understood that this invention is equal ly useful when employing but a single carbon sheet betweentwo record sheets, the foremost of which receives the main or ribbon impression of the type while the second receives the record through the medium of the carbon. Itis therefore to be understood that this manifolding device is equally useful when employing a single carbon sheet or a plurality of carbon sheets, and in the following description and claims the term carbon sheets is to be understood as including either a single sheet of manifolding carbon or a plurality of such sheets.

This manifolding device is more particularly intended for use in continuous billing in which the record is simultaneously made on a plurality of sheets or leaves constituting a set, and each set forms a section of a plurality of webs or continuous sheets or strips which have been previously folded in zig-zag fashion and stacked in a pile in rear of the typewriting machine, as shown in Fig. 9, preparatory to being fed successively through the typewriting machine for producing records of various kinds on the several sets of record sheets. As the record on each set of typewritten sheets is completed the respective set of record sheets is torn or severed from the sheets in the next following set or section of the plurality of webs preparatory to producing another record on the last-mentioned set of record sheets. The line of division between one set or section of record sheets and the next following set or section of such sheets is preferably located in the folds l9 between the adjacent sections of the several webs and along these folds each of the webs is provided with a transverse line of perforations 20, as shown in Figs. 6 and 7, so as facilitate tearing one set or section of sheets of the web from another set or section thereof. If desired, however, the severing of one set or section of the sheets in the continuous web from the sheets of another section thereof may be effected by any suitable form of cutting device which may be operated either manually or mechanically.

In its preferred form the frame of this manifolding device comprises two vertical end plates or heads 2|, 22 arranged lengthwise over the platen and the carriage bars l1, l8 adjacent to opposite ends thereof, a lower horizontal transverse bar or rod 23 arranged above the platen and connecting the lower parts of said end plates, and an upper horizontal transverse bar or rod 24 arranged above the lower bar 23 and-connecting the upper front parts of the end plates.

On its underside each of the end plates is provided about midway of its length with a downwardly facing V-shaped seat 25 which engages with the correspondingly shaped seat on the upper side of the carriage bar [1, as shown in Figs. 2 and 5. At its rear end each of the end plates 2|, 22 is provided with a notch 26 forming in ef-' feet a forkwhich extends rearwardly and receives the rear cross bar [8 of the carriage, as shown in Figs. 2, 3 and 5. The manifolding frame may be held in engagement with the carriage by any suitable means, but this is preferably accomplished by means of catches 21 movably mounted on the outer side of each of the manifold end plates about midway of the length thereof, and each provided at its lower end with a hook 28 engaging with the underside of the adjacent carriage bar I! and provided between its ends with a longitudinal slot 29 which receives a clamping screw 30 on the adacent part of the respective end plate, a finger piece 3! arranged at the upper end of each catch 21 for convenience in manipulating the same, and a screw nut 32 working on the respective clamping screw 30 and engaging with the outer side of the catch 21, as shown in Figs. 1, 3, 4 and 5.

Adjacent to opposite ends of the manifolding frame the same is provided with two pairs of gripping devices whereby the carbon sheets may be gripped and held against longitudinal movement but permit the record sheets to be moved 5 lengthwise independently of the carbon sheets, and these gripping devices may also release the carbon sheets so as to permit the same to move lengthwise through the machine with the record sheets. 10

Each of these gripping devices comprises a rear gripping jaw 33 which is inclined rearwardly and arranged in rear of the corresponding edge portions of the record sheets and the manifolding sheets at one of the corresponding longitudinal l5 edges thereof, and a front jaw 34 which is arranged in front of the companion rear jaw and in front of the corresponding longitudinal edge portion of the manifolding sheets, but beyond the adjacent longitudinal edges of the record sheets. It follows from this construction that when the two gripping jaws of each pair are pressed together, only those edge portions of the carbon sheets which project beyond the record sheets will be gripped and thereby hold the carbon sheets against motion but permit the I. record sheets to be moved lengthwise independently of the carbon sheets, while upon releasing the jaws from the carbon sheets the latter are free-to move lengthwise with the record sheets. In the preferred construction each of the rear gripping jaws is pivotally mounted to swing in a vertical plane lengthwise of the machine, for

. which purpose this jaw is provided at its vertical opposite edges with rearwardly projecting flanges 35 which are pivoted at their upper ends on the upper cross bar 34 of the manifold frame. In order to permit each of these rear gripping jaws to swing the requisite extent without interference with the lower manifold frame bar 23 the flanges 40 35 are provided in their lower parts with rearwardly opening notches 36 which are opposite the bar 23 and therefore clear the latter upon swinging the respective rear gripping jaw 33 forwardly and backwardly, as best shown in Fig. 2. Each of the front gripping jaws 34 is stationary relative to the companion rear gripping jaw but is pivotally mounted so that the same can swivel or turn in a vertical plane lengthwise of the machine a sufficient extent to permit I this front jaw to freely adapt itself to the front side or surface of the side edge portions of the respective carbon sheets. For this purpose each of the front gripping jaws is pivotally connected by means of a horizontal transverse pin 31 with a rearwardly projecting finger 38 which is formed on the front end of an arm 39 which is secured at its rear end to the adjacent end plate of the manifold frame.

The movement of the rear jaw toward and 6 from the companion front jaw of each pair for either gripping or releasing the grip on the carbon sheets may be effected in various ways but the means which are shown for this purpose in the drawings are so organized that a yielding pressure is exerted against each of the rear gripping jaws and thus enable each pair of gripping jaws to automatically adapt themselves to variations in the thickness of the carbon sheets and also to any variation in the number of carbon sheets which may be employed.

As best shown in Figs. 2, 3 and 4 a cushion spring 40 preferably of leaf form is arranged in rear of each of the rear gripping jaws and secured thereto at its upper end while its lower end is free, and in rear of the free part of each of these springs is arranged a rotary cam or eccentric 4I, which latter upon being rotated so as to engage its salient part with the cushion spring 40 will cause the respective rear gripping jaw to be moved toward the companion front gripping jaw for holding the respective ends of the carbon sheets against movement, while upon turning this cam or eccentric so as-to present its receding part to the cushion spring the pressure on the respective rear gripping jaw will be released and thereby permit this jaw to drop by gravity away from the rear side of the carbon sheets and permit the latter to be moved in the machine.

The eccentrics or cams associated with the two pairs of gripping jaws on opposite sides of the manifold frame are turned in unison into and out of their operative position by means of a horizontal transverse shaft 42 which is journaled at its opposite ends in the end plates of the manifold frame, and is provided at one end with a hand lever-or arm 43 for operating the shaft.

The throw of the cams 4| into and out of their operative position is preferably limited by means of front and rear stops 44, 45 arranged on one of the end plates of the manifold frame adjacent to the shifting lever or arm 43 so that when the cams 4| are moved rearwardly into their inoperative position the shifting lever 43 will engage the rear stop 45 and when the cams move their salient parts against the cushioning spring 40 said hand lever d3 engages with the front stop 44 and limits the movement of the cams in this direction.

The arrest in the operative movement of the cams preferably occurs when the salient faces of the same are on a dead center or slightly beyond such center so that the pressure of the cushioning springs 58 will operate to hold the shifting cams in their operative position without requiring any other mechanism for this purpose and still permit these cams to be easily released from the cushioning springs and moved into their rearward inoperative position when required.

In the use of this manifolding device one or more carbon sheets are assembled with the two or more leaves or sheets in the first section or set of the continuous webs, so that the opposite ends of the respective carbon sheet or sheets project laterally with their longitudinal edges beyond the corresponding longitudinal edges of the record sheets; The front ends of the foremost set of assembled record and carbon sheets are then passed downwardly between the rear side of the platen and the rear g ide roller it, thence upwardly between the underside of the platen and the front lower guide roll it and then the advancing edges of these record and carbon sheets are moved at their opposite longitudinal edge portions over the rear jaws of the two pairs in such position that the record sheets clear the front gripping jaws but the longitudinal marginal parts of the carbon sheets are brought underneath the front jaws of the two pairs of gripping devices, as shown in Fig. l.

The record sheets and carbon sheets are now in condition to permit of producing a multiple record consisting of a ribbon impression or writing on the foremost record sheet and carbon impressions of the type on the remaining inner sheet or sheets through the medium of the intercalated carbon sheets in a well-known manner.

The length of the carbon sheets is preferably so determined that the same do not exceed the length of the sheets or leaves in each set or sec-- tion of the webs, and these are so assembled that the carbon sheets are within the boundaries of the respective record sheets, as shown in Fig. 6. 5 After the desired record has been typewritten on the record sheets by the manipulation of the type bars and the means for shifting the carriage transversely and also feeding the paper lengthwise as the writing progresses, the operator advances both the carbon and record sheets lengthwise a sufficient extentto bring the lower or rear ends of the carbon sheets underneath the front jaws of the two pairs, as shown inFig. 6. The

rear jaws of the two pairs are now pressed forwardly by rotating the cams 4! in the proper direction through the medium of-the hand lever 43, whereby the marginal parts of the carbon sheets are gripped adjacent to their lower or rear ends between the two pairs of gripping jaws, as shown in Figs. 2 and 4, and these carbon sheets. are held against longitudinal movement. The operator now retracts the lower guide rollers l3 and I4 so as to release the webs of record sheets and permit the operator, by grasping the upper ends of the .foremostset of leaves or sheets of these webs, to pull the same forwardly independently of the carbon sheets a suflicient extent to bring the line of division between the foremost set of sheets and the next following set of sheets above the upper edge of the set of carbon manifolding sheets. When this has been done the operator can separate the set of completed rec- 0rd sheets having the desired writing thereon by severing this foremost set of record sheets from 3 the next following set of record sheets, which in. the present instance is best accomplished by tearing these two sets of sheets apart along the lines of perforations located at the creases or folds between the rear ends of the sheets of the fore most set and the front ends of the next following set of record sheets.

During this operation the set of sheets of the webs which now becomes the foremost set of the webs has its lowermost part arranged adjacent to the printing line of the platen, and it is therefore necessary to back up the webs in order to bring the top of the sheets of the foremost set of the web to the printing line for the purpose of starting the writing of another record. Before, however, backing up the sheets of the rec- 0rd webs the cams 4| are turned so as to release the grip of the two pairs of jaws from opposite ends of the carbon manifolding sheets so that when therecord sheets are moved backwardly for bringing the top of the foremost set of sheets to the printing line the carbon sheets will be also moved backwardly with these record sheets and in the proper position to produce multiple copies of the record as the writing of the same progresses. This operation of gripping the lower end of the set of carbon sheets at the completion of each writing operation on a set of record sheets, then drawing the webs forwardly so that the foremost set of sheets of the web are clear of the carbon sheets and bringing the next following set of sheets into an intercalated position relative to the carbons, then tearing off the foremost set of finishedJrecord sheets from the next following set which is intercalated with the carbon sheets, and then releasing the carbons and backing the I same up with the associated record sheets forbeginning a new typewriting operation-is repeated in like manner for each manifolding operation.

From this it will be seen that the carbon sheets 7 need only be inserted manually once between the foremost set of sheets or sections of the continuous webs, and that thereafter the same carbon sheets may be used repeatedly in association with the sheets or leaves of successive sets or sections of the webs without necessitating assembling and' disassembling the carbon sheets and succeeding record sheets, as has been the usual custom heretofore, thereby materially expediting the production of multiple records of this character and reducing the time required for this purpose as well as effecting a substantial saving in cost for doing the same.

It has been found in actual practice that when drawing a plurality of record sheets for wardly relative to one or more carbon sheets while the latter are held stationary in order to transfer the carbon sheets from the foremost section or set of sheets of the webs to the next following set or section of sheets that the shoulders which exist at the folds between adjacent sections are liable to catch the lower transverse edge or edges of the carbon sheets and either crumple or tear the same so as to interfere with the manifolding operation or impair the quality of the manifold work which results from either tearing the carbons or wrinkling the same.

This tendency of the record sheets to catch at the turns between the same on the lower edge of the carbon sheets is further increased when the line of division between adjacent sets of sheets at the turns thereof is defined by the perforations 20 which are usually employed to facilitate tearing or, severing of one set of sheets i from another in the webs.

The catching of the record sheets against the lower edges of the carbon sheets by engagement of the shoulders or perforations at the junction between adjacent sets of record sheets in the web is due to the fact that these shoulders and perforations are arranged along transverse lines on the webs and engage simultaneously with the lower edges of the several carbon sheets if these lower or rear edges of the carbon sheets are also arranged on a transverse line which is arranged at right angles to the longitudinal movement of the record sheets. If such a simultaneous engagement of the shoulders or perforations at the division line between adjacent record sheets'with the lower edges of the several carbon sheets is permitted to occur a substantial upward pull would occur on the carbon sheets along substantially the entire lower edge which the carbon sheets are not capable of resisting due to the delicate character of the tissue from which the same are made. Such displacement or rupturing of the carbon sheets is objectionable and seriously interferes with the proper operation of this manifolding device.

In order to avoid this result the lower transverse edge of each carbon sheet is arranged obliquely or at an angle to the longitudinal line of movement of the record sheets, as shown at 46 in Figs. 6, 7 and 8. As a result of the angularity of the lower edge of each of these carbon sheets the transverse shoulder which is formed by the fold, crease or line of perforations on the record vebs between adjacent sections or leaves at right angles to the longitudinal line of movement will only engage with the oblique lower edge or edges of the carbon sheets along a comparatively small area of contact at any one time, as indicated at 4' in Fig. 7. This area of contact between the shoulders of the record webs'along the lines between adjacent sets of sheets and the lower edges of the carbon sheets will therefore begin at the lowermost part of the oblique lower .edge of the carbon sheets adjacent to one pair of clamping jaws and then progress successively upwardly and transversely across the inclined lower edges of the several carbon sheets toward the other pair of carbon sheet holding'laws, and then slide off in between the broad faces of the several carbon sheets.

It follows from this that the lower edges of the carbon sheets are at no time engaged over any considerable area by shoulders on the record webs and no tendency therefore exists to produce any substantial pull over any considerable area of the lower edge of the carbon sheets, whereby the latter are not drawn upwardly from their lower edges and neither distorted or displaced to such an extent that they are torn or wrinkled, whereby the objectionable results above-mentioned are avoided.

Although it is only necessary to arrange the lower edges of the carbon sheets obliquely for the purpose of accomplishing the above results, it is also preferable to construct the upper edge 41 of each carbon manifolding sheet of oblique or angular form relative to the longitudinal line of movement of the record sheets, as shown in Figs. 6 and '7, in order that the same carbon may be interposed between the record sheets with either of its transverse edges arranged at the rear end thereof and thus avoid any particular care on the part of the operator when assembling such carbon sheets with the record webs.

If desired, however, only the lower edge of the carbon sheet may be of oblique form and the upper edge thereof may be arranged at right angles to the longitudinal line of movement of the record sheet through the machine, as shown at 48 in Fig. 8.

In both cases, however, the longitudinal edges 49 of the carbon manifolding sheets are parallel with the longitudinal line of movement of the record sheets inasmuch as this form of sheet is more practical from a manufacturing standpoint, and it is also desirable for the same reason to make both the upper and lower edges of the carbon sheets of oblique form and parallel with each other so that the same in effect have the shape of a parallelogram.

In order to permit of thus holding the carbon sheets securely at their lower edges while arranged obliquely relative to the length of the machine and the line of movement of the record sheets the rear jaws of both pairs of grippers are preferably of the same length but the companion front jaw of one pair, for example the right hand jaw 34 as shown in Figs. 1, 6 and '7, is arranged somewhat lower than the front jaw associated with the pair of grippers at the left hand side of the machine, which relative longitudinal displacement of these two front jaws corresponds to the angularity of the lower edge of the carbon sheets and enables both of these front jaws to grip the carbon sheets at their lower edges adjacent to the side edges thereof in cooperation with the rear jaws. By this means the several carbon sheets are held properly in position against liability of being wrinkled by the upward movement of the record webs when substituting an unwritten set of sheets for the previously completed set of sheets, while at the same time leaving those parts of the carbon sheets above the clamping jaws free to be smoothed out by the upward sweep of the record sheets past thesame and thus maintaining the carbon sheets always in a smooth and unwrinkled condition for producing good carbon reproductions of the typewritten matter.

It has been found by experience that no difiiculty is experienced in feeding those upper edge portions of the carbons underneath that particular front gripping jaw which is lowermost, but in the manipulation of the carbons the upper parts of the carbons adjacent to the opposite longitudinal side thereof are apt to be turned back or curled over by engagement with the low er end of the elevated or left hand front gripping jaw due to an interference between this jaw and the carbon sheets. In order a; avoid this the front upper or advanced gripping jaw, which in this case is at the left hand side of the machine, is provided at its lower edge with an inclined guide 50 which projects forwardly a sufficient extent so that when the operator moves the left hand edge of the carbons upwardly the same will be directed by the guide 50 underneath the left hand jaw 34 without any liability of interference between these parts or any displacement of the carbon sheets.

. In the standard Royaltypewriter the record sheet, when using the machine for ordinary writing, is held down upon the upper part of the platen by means of guide rollers which are mounted on a shaft 52 having its opposite, ends movably connected by means of vertically swinging'arms 53 with the rear part of the carriage. Inasmuch as the rollers 5| would interfere with the application of the present manifolding device to the Royal typewriter these rollers are moved upwardly and rearwardly away from the platen in the position shown in Figs. 1, 2 and 3, and utilized as part of the guide means for directing the webs of record sheets from the supply stack to the platen.

If desired the faces of the gripping jaws may be serrated, scored or grooved, as shown at 54 in Fig. 5, for the purpose of increasing the hold of the same on the carbon sheets. v

As a whole this manifolding device is very simple in construction, the same has comparatively few parts, all of which can be readily manip- I ulated without liability of getting out of order, and the same can be readily applied to and removed from typewriters of standard construction, and thus permits the same typewriter to be conveniently used either for ordinary typewriting or for continuous billing.
