MANIFOLDING DEVICE.

SPECIFICATION forming part 0f Letters Patent No. 756,258, dated April 5, 1904.

Application filed .Tune 13, 1901.

To @ZZ whom, t may concern;

Be it known that I, ISAAC H. MALLIN, a citizen of the United States, residing at Chicago,V in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Manifolding Devices, of which the following is a full, clear, and exact specification.

This invention relates to improvements in manifold devices designed for simultaneously producing in duplicate or multiple Ainksheets-that is to say, inked copies-said device embracing one or more ink-sheets sul)- stantially corresponding in dimensionsto the type-written sheets to be produced, the said ink-sheet having atype-protecting or backing sheet of corresponding size preferably interposed between the platen of a type-writing machine and the paper to be written upon.

Prior to my invention ink-sheets with backing-sheets, such as is described, have been detachably connected together in such a manner that the permanency of their relations is not and cannot be maintained at all times, and as a result the sheets of paper upon which the duplicate and, multiple ribbon inked f copies are to be simultaneously made cannot be with certainty maintained in that relation to each other o r to the 'type-Writer mechanism to produce parallel lines of type-writing which are also parallel with the ends of the sheets or which would insure the ends of the lines terminating at the same point relative to the side edges of the sheets on the several duplicate ribbon-inked copies. In other words, in order to successfully produce duplicate and multiple ribbon -inked type written sheets at one operation of the type-writer it is absolutely necessary that the several letter-heads upon which these several ribboninked copies are to be simultaneously produced, and also carbon copies, if any are to be produced at the same time, shall not only be arranged but maintained throughout the type-writing operation with almost mathematical exactness both with reference to each other and the ink-sheet and also the carbonsheets when one or more are used. This mathematical exactness must be maintained from the time the sheets are inserted in the type-writer until discharged therefrom after being type- Serial No. 64,380. (No model.)

written, for otherwise the writing upon lthe dierent sheets will not correspond in the direction of the lines with reference to the top and bottom edges of the sheet, nor as to the termination of the lines with reference to the side edges of the sheet, and hence one or more of the sheets will be unsightly even though the ink-sheet be maintained thoroughout the type-writing operation in a perfectly smooth condition.

To the unsightliness resulting from the absence of parallelism between the lines of typewriting and the top and bottom edges of the sheet and right angularity of the type-written lines of the side edges of the sheet will also be added actual disiiguration and possibly partial obliteration of the type-writing ifat any time during the type-writing operation either the ink-sheet or the other sheets are drawn taut at one portion and slack at another. It may also be observed that the largest surface of the ink-sheet Will also be unused, and the corresponding lack of economy, convenience, and saving of time willoccur, owing to the uniform spacing of a type-writing machine. vided for shifting the paper sheet relative to the ink-sheet, or vice versa, so as to successively present the previously-unused surface of the ink-sheet to the type when other portions are worn out by the action of type; but

it is obvious that this very desirable result cannot be successfully accomplished without means by which the ink-sheet and the paper sheet are maintained in perfect register when so shifted. In this connection it should also be observed that any shifting of the ink-sheet or the other sheets for the purpose of exposing a new inking-surface is not practicable when it requires any manipulation of the inksheet, its protecting sheet, or a manipulation of the sheets to be written upon diiferently from that commonly employed for arranging them upon an ink-sheet. f

The prime object of my invention is a manifold device for simultaneously producing from an ink sheet and sheets duplicate or manifold type written sheets, which device shall be of simplest possible construction and which provides not only for arranging all of the Some means should therefore be pro- IOO sheets to be written upon in registry of each other and with the ink-sheet, but which shall' at the same time permanently maintain said sheets to be written upon and ink-sheet in registry with each other and with the typewriting machine and in such a manner that all of said sheets may be con veniently inserted in a type writing machine and permanently maintained in registry throughout the entire travel of all of said sheets through the machine.

A further object is to provide a manifold device of a construction providing the simplest possible means for utilizing previously-unused portions of the ink-sheet after other portions have been used up and at the same time maintain said ink-sheet in registry with the several sheets to be written upon.

A still further object is to provide a manifolding device having an ink-sheet with a protecting sheet or backing, which said sheets are secured together in such a manner that both ink-sheet and the backing-sheet shall be maintained in a perfectly smooth condition throughout their surfaces, and this particularly as to the ink-sheet during the entire travel of the ink-sheet through a type-writing machine.

lith these ends in view my invention consists in certain features of novelty and construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings and more particularly pointed out in the claims.

In the said drawings, Figure l represents a plan view of a manifolding device embodying my invention and showing the ink-sheet imposed upon the backing-sheet. Fig. 2 is a longitudinal side elevation of the same; Fig. 3, a detailed section through the binder thereof, and Fig. 4 a transverse section on the line 4 4 of. Fig. 1.

Similar numerals of reference indicate the same parts throughout the several figures of the drawings.

1 indicates a backing-sheet upon which is placed and secured an ink-sheet 2, both faces of which are preferably inked, which inl:- sheet may be of the same length as the back'- ing-sheet, but is preferably somewhat shorter and narrower for convenience in handling and to avoid soiling the hands. The ink-sheet is preferably substantially of the same length as the sheet or sheets of paper to be used in connection therewith and of a width corresponding with the distance between the outer ends ofthe feed-rollers of the machine, so that it will be grasped by both rollers in passing through the type-writing machine. The inksheet and the backing-sheet are preferably secured together by a binding-strip 3, folded upon itself and around the ends of the backing-sheet and the ink-sheet, so as to overlie both sides of a substantial portion of the surface of both sheets, the said binding-strip being secured in this position by stitching 4, which for the purposes of my invention is in two or more parallel rows, and for the purposes hereinafter described this stitching is preferably single-thread stitching, so that it may be removed. In this connection it is.

proper to note that the binding-strip between the last row of stitching and its ends is preferably pasted or cemented to both the inksheet and the backing-sheet instead of turned up therefrom, as illustrated in Fig. 3.

In order to maintain the ink-sheet in a smooth condition and at the same time provide for inserting aduplicate sheet upon its under side to be printed upon, said ink-sheet is alsov 1 stitched near its end edge to the backing-sheet,

as shown at 5, at the end opposite therefromv from the binding thereof to the backing-sheet. To further promote the smoothness of the inksheet throughout its surface, it is provided longitudinally along both of its side edges and at the point at which the ink-sheet would otherwise contact with the feed-rollers of a typewriting machine with narrow strips of paper or cloth 6 6 or other suitable material, whichV extend from the binding-strip to the farthest end edge of the ink-sheet; but it will be no substantial departure from my invention in its broad sense to omit both strip 6 and the stitching 5.

In producing duplicate type-written inked placed in a corresponding position, so that both sheets are made to perfectly register when placed in the type-writing machine and throughout the operation thereof.

If desired, the binding-strip may be slightly bent outwardly from the ink-sheet and the backing-sheet, as shown in Fig. 3, and in such a manner that the one sheet projected between the upper surface and the ink-sheet will be wedged and locked between the binding-strip and the ink-sheet. On the other hand, the two sheets to be written upon may be made to register with each other by abutting the upper sheet against the edge of the bindingstrip and the lower edge of the under sheet against the stitching at the opposite end of the ink-sheet. With the sheets thus maintained in register and in their proper relation both to the ink-sheet and to each other and inserted in a type-writing machine the strip 6 will pass between and be held by the feedrollers of the machine, and as a result the inksheet will be held by these strips against sagging, while at the same time the sheets to be written upon will be held in such a manner IIO that the ink-sheetwill be held in a smoothed condition throughout its surface during the entire operation of the type-writer. In devices of this character it is obvious if vthe sheets are always maintained -in a fixed relation to the ink-sheet opposing portions of the ink-sheet at intervals thereof will in time be used up, while other portions will remain unused; but as a convenient means for avoiding this objection and by whicli the ink-sheet may be entirely used up my invention includes two or more parallel rows of stitching, which serve not only to secure the backing-sheet and the ink-sheet together, but which provide a simple and eifective means by which after portions of the ink-sheet are used up other and unused portions may be utilized until the inksheet is worn out, while in the meantime the binding-stitch serves as abutments for registering the sheets. To these ends when opposing portions of the ink-sheet are worn out a fresh portion may be used by drawing out one line of the stitching-as, for instance, the lower line 4: in Fig. l-and then registering the sheets, to be printed on, against the next line 4, which shifting of the sheets from their first position enables the using up of unworn portions of the ink-sheet and at the same time provides for maintaining the proper registry of the type-written portions relative to the sheet-that is to say, to the letter-head of the sheet. Obviously if such shifting were not made the writing from the iinal unused portions of the ink-sheet would have to be an objectionable distance below the letter or bill head, as may be, whereas by drawing out one line of the stitching the letter-head is lifted relative to the unused lportions of the inksheet so that the inking from the unused portions lthereof may be started at the same point relative to the letter-head or bill-head as was done when the inkwas iirst'used. The advantage of my invention in this respect may be apparent by bearing in mind that'it requires no skill and practically no time when certain opposing portions of the ink-sheet is worn out to withdraw one of the lines of stitching and shift the letter-heads accordingly for receiving for the operation of the unused portions of the ink-sheet. After this convenient withdrawal of one row of stitching the next row of stitching provides a registering-gage for the sheets, so that throughout the operation of using up the ink-sheet in its entirety a perfect registration of the sheets with each ,other and the printed matter relative to the letter-heads and bill-heads is preserved, and in this connection it should be `observed that in my construction this can be done without contacting the hands with the ink-sheet, and thereby-soiling them.

'Ihe binding-strip is preferably of a thickness corresponding with that of the sheets to be written upon, so that when the sheets are in place the binding-strip will pass smoothly through the feed-rollers, and substantially this feature of thickness should be observed in order to obtain the best result in use of the guidestrips 6 6. l

,While there are shown in the drawings but two rows of stitching, it is obvious that further rows may be employed, if desirable or necessary, for entirely using up the inkingsurface of the ink-sheet, and it is equally obvious that any other means providing for this result which is the equivalent of stitching. in the function it performs will be within my invention.V v

It would be no substantial departure from my invention to omit the binding-strip and have the backing-sheet of such a length that it might be folded over upon the ink-sheet and then securing the two sheets together by parallel lines of stitching passing through the three thicknesses thus formed. It is, however, preferred to use the binding-strip, and especially when it is desirable to also lproduce carbon copies, because the under transverse edge of the binding-strip affords a means for registering the under sheets owing to the binding-strip forming an abutment against which the top edges of these sheets maybe set, and as it is generally customary to use one or more carbon-sheets in connection with the duplicate ink-sheets, the under side of the binding-strip facilitates the introduction of the several sheets into the type-writing machine, while at the samek time the carbonsheets in conforming to the thickness of such edge produce a surface of uniform thickness throughout the manifold device itself.

The combined thickness ofthe ink-sheet, the backing-sheet, the binding-strip, and the lsheets to be written upon subject the inksheet to such a severe pressure when thev bound end of the manifolding device is forced in between the feed-roll and the platen-roll or between the platen-roll and any other guiding means that the sheet or sheets to be written upon which lie contiguous to the ink-sheet are liable to be discolored, and in order to preventl this a plain uninked strip 7 is secured along the upper edge of the ink-sheet where the latter is embraced or overlapped by the binding-strip 3, and, if desired, a similar strip 8 may be secured to the opposite side of the ink-sheet for preventing the latter from soiling the carbon-copy at the point where this excessive pressure occurs.

Instead of having a single ink-sheet doublefaced-that is to say, inked on both sides-it would be no departure from my invention to use instead thereof two or more ink-sheets each having a single face-that is to say, inked upon but one side; but i-n practice it is preferred to use the double-faced ink-sheet.

Having described my invention, what I `claim as new there-in, and desire to secure by IOO bination an ink-sheet and a backing-sheet seby two or more transverse rows of stitching,

substantially as described.
