SNAP-OUT MANIFOLDING UNIT Filed Jan. 23, 1957 2 Sheets-Sheet 2 INVENTOR. JAMES W- KEHOE Y E/CHgY, WATTS, EOGEETON, HS-NNY&FAPIE/N6TOM v United States Patent Office 3,081,111 Patented Mar. 12, 1963 Ohio Filed Jan. 23, 1957, Ser. No. 635,848 4 Claims. (Cl. 282-22) This invention relates to the art of manifold record devices and is particularly concerned with a new unit set, manifold record pad and a new method of making record pads.

It has been common practice to make manifold record sets consisting of an original sheet, one or more copy sheets and as many carbon sheets as copy sheets. Various means have been proposed for quickly separating the carbon sheets from the other sheets and pads provided with such means and known as snap-out sets or unit sets. Usually these means involve the use of carbon sheets which are not as long as the other sheets or one set of sheets is mutilated at the free end so that the carbon sheets may be detached and separated by grasping the ends of the pad with both hands and moving the hands apart.

There are certain disadvantages inherent in such pads. The different length sheets or the mutilation of some of them impose restrictions on the manner of making the pads. For example, when the carbon sheets are shorter than the other sheets, the sheets cannot be economically arranged in pads with the grain running lengthwise of the sheet. This is a disadvantage because of the cost and also because original and/or copy sheets of the Hollerith card type cannot be used in such pads for their length and other physical characteristics must be held within quite close tolerances and such tolerances cannot be maintained when the grain runs across the sheet. It is to be understood that in the manufacture of paper on a conventional paper-making machine, for use in producing tabulating card stock, some of the fibers which were randomly oriented when the pulp was fed onto the dewatering screen are subsequently rearranged so that in the finished paper a majority of the fibers extend lengthwise of the sheet; that is, parallel to the direction of travel of the sheet during its manufacture. These fibers constitute what is referred to herein as the grain of the sheet.

The present invention aims to avoid those disadvantages and achieves that aim by providing a new snapout manifold set in which the sheets are all of the same length and are not mutilated at the free end and also by providing a new method of making manifold record pads which enables convenient extraction of carbon from the set after it ha been used.

The present invention will be better understood by those skilled in the art from the following specification and the accompanying drawings in which:

FIG. 1 is a plan view of a unit set or snap-out manifold set embodying the present invention;

FIG. 2 shows the carbon sheet retained by the stub of the set of FIG. 1 after it has been snapped out from between the original and copy sheets;

FIG. 3 is a plan view of a slightly modified form of unit set embodying this invention;

FIG. 4 is a perspective view of a book consisting of a plurality of sheets embodying this invention; and

FIG. 5 is a diagrammatic showing of the new method of making the unit set of FIG. 1.

The unit set illustrated in FIGS. 1 and 2 comprises an original sheet 1, a copy sheet 2, and a carbon sheet 3, these three sheets being connected together at one end by a stub 4 which consists of a narrow portion of each of these sheets secured together in permanent form. (It

is to be understood that any desired number of copy sheets and the same number of carbon sheets may be assembled in a pad and that the simplest form of pad is illustrated in FIGS. 1 and 2 for the purpose of simplicity and clarity.

It will be observed that each of the sheets of the unit set of FIGS. 1 and 2 is connected to its tab portion only by transversely short spaced integral connections. It will be noted from FIG. 1 that the original sheet has a plurality of cuts 5; and another parallel set of cuts 6 similarly arranged and parallel to cuts 5. Cut 7 is in line with cuts 6 but is differentiated from 6 because it is made in a different operation which is described later. This arrangement of

cuts

5, 6 and 7 does not completely separate the original sheet from its tab end because the sheet and the tab remain connected at the ends of the 7

several cuts

5, 6 and 7. While this connection is weak,

it is sufficient for the original and copy sheets and its tab end to hold together under ordinary handling but is insuflicient to prevent ready separation of these two parts when pull is exerted on them in opposite directions longitudinally of the sheet. Copy sheet 2 is similarly separated from its stub end by cuts 5a, 6a and 7a quite like

cuts

5, 6 and 7 of sheet 1; and the main part of the copy sheet i connected to its stub end in the same way as sheet 1 is connected to its stub end. Thus it will be understood that when the stub ends of these two sheets 1 and 2 and the sheets them-selves are pulled apart lengthwise thereof, they will be readily separated from their stub as just described in connection with sheet 1. p The carbon sheet 3 is also provided with several transverse cuts 5b and 6b like the

cuts

5 and 6 of sheet 1 but the carbon sheet lacks a cut similar to cut 7 and is provided with a thumb tab 8 formed by cut 9 at its stub end and connected to the body part of the carbon sheet underlying the middle cut 7 of original sheet 1. Thus when the original and copy sheets are separated from their stub end-s, the carbon sheets will be retained with the stub by reason of the fact that this thumb tab 8 will be held between the thumb and finger of the user or by reason of this tab being pasted to the original or copy sheet above. Thus the carbon sheets and stu-b will remain together when they are snapped out from between the original and copy sheets. Cut 9 may be omitted, if desired, in which case the tab 8 will extend entirely across the stub.

It will be noted that the carbon sheet 3 has a thumb notch 10 at the end opposite the tab 8. The thumb notch 10 permits one to grasp the set with thumb and finger at the location of this thumb notch with one hand and the stub end With the other hand and pull the original and copy sheets away from the carbon heets for convenient removal of carbon from its used set. p

The stub ends of the several sheets are connected together in any suitable manner but, as illustrated in FIGS.

1 and 2, these several sheets are glued together. It will be noted that the carbon sheet has a plurality of perforations 12 in its stub end on opposite sides of the thumb grip. During the assembling of the several sheets adhesive material, such as a suitable glue, is placed on the copy sheet where it may flow through these perforations and onto the original sheet, thus binding together the three sheets shown in FIGS. 1 and 2. It will be understood that when more than three sheets are so, assembled it may be necessary to apply the adhesive to more than one of the copy sheets, or even to each of them, to accomplish the desired connection of the several sheets into a pad.

The unit set shown in FIG. 3 isquite like that shown in FIG. 1, the main difference being in the location of the thumb cut-outs on the carbon sheets. As shown at I 3 15 this cut-out is at a corner of the carbon sheet instead of in the middle as in the modification of FIGS. 1 and 2. Otherwise the set of FIG. 3 is practically identical with that of FIGS. 1 and 2.

FIG. 4 shows the present invention embodied in a book or multiple pad consisting of a plurality of unit sets stapled together in book-like form. Aside from stapling a cover 16 to the stub and the absence of glue to hold tab 8 to the original or copy sheet above it, the pad of FIG. 4 is made up of unit sets which may be like those shown in FIG. 1 or FIG. 3. The cut 7a may be omitted, if desired, in which case the record copy may be retained in the book for convenience in storing or filing.

The present method invention and manner of carrying it out in the production of unit sets as described above is illustrated diagrammatically in FIG. 5.

In FIG. 5, rolls of original sheet paper 20, carbon sheet paper 21 and copy sheet paper 22 are disposed preferably in the illustrated vertical arrangement, although other arrangements may be used provided that the coils are so disposed that the paper therefrom may be superimposed to form the multiple pad or unit set of FIGS. 1 to 3.

The paper is drawn off the three

rolls

20, 21 and 22 continuously, simultaneously and necessarily lengthwise of the grain of the paper, and these sheets are fed through suitable cutters and gluers, and then are brought into superposed relation where the gluing step is completed and the superimposed strips or sheets are cut into unit sets of the desired length. Slitter unit 28 will divide the paper longitudinally to provide a multiple production of unit sets of the desired width.

In carrying out these steps the copy paper or roll 22 is passed through a cutter which forms the cuts 7 which are described above. This cutter may be of any conventional form but, as illustrated, comprises a fixed die 23 and a knife 24 provided with edge to perform the cuts 7a. Then glue, or other suitable adhesive, is applied to the copy strip as at 25 and the strip then passes on to a die 26. Similarly carbon paper from roll 21 passes onto a die 23a where a cutter 24a forms the

cuts

9, 10 and 12 therein, as described above. Then the carbon strip proceeds on to a position above die 26 where it is brought onto the copy sheet then on die 26. In a similar fashion the original sheet from roll 20 is moved over a die block 23b and is there provided with the cuts 7 by cutter 24b, after which the copy paper is moved into superposed position onto carbon sheet 21 just above die 26.

While the thus superposed sheets are pressed together on die 26, they are severed by a suitable knife head 27 which forms cuts along what will become the free end of the unit set and produces cuts and 6 in the original, cuts 5a and 6a in the copy sheet and cuts 5b and 6b in the carbon sheets, all simultaneously. During this operation of cutting transversely across the assembled sheets, and during the slitting operation at 28, the glue which was placed on the copy sheet will spread upwardly through the holes in the carbon sheet and will contact the under surface of the original sheet and will cause these several sheets to adhere to one another.

When multiple pads like those shown in FIG. 4 are to be made, they are assembled in superposed position and are stapled in the holder shown in FIG. 4.

An important advantage of this method of manufacture is that the sheets may be run from the rolls in the direction of the grain of the paper and hence the sheets of the unit set or pad will be maintainable within the very close tolerance limits required for use of these sheets on machines where Hollerith type cards are required. Another advantage is that by avoiding mutilation of the ends of the sheets of the pad and making all the sheets of the same length, the rate of manufacture may be quite rapid as compared with conventional methods where some sheets are mutilated at the ends or are shorter than other sheets.

Having thus described this invention in such full, clear, concise and exact terms as to enable any person skilled in the art to which it pertains to make and use the same, and having set forth the best mode contemplated of carrying out this invention, I state that the subject-matter which I regard as being my invenion is particularly pointed out and distinctly claimed in what is claimed, it being understood that equivalents or modifications of, or substitutions for, parts of the above specifically described embodiments of the invention may be made without departing from the scope of the invention as set forth in what is claimed.
