Specification of Letters Patent.

Patented Feb. 19, 1918.

Application filed January 6, 1917. Serial No. 140,898.

To all whom it may concern:

Be it known that I, SvEN Josnr FREDRIK BERGENDAHL, a subject of the King of Sweden, residing at Gottenborg, in the county of Gottenborg and Bohusand Kingdom of Sweden, have invented new and useful Improvements in Manifold Recording Books or Pads, of which the following is a specification. I

This invention relates to manifold recording books or pads of the class wherein the single sheets, which are all joined together by means of a common stub are folded into a plurality of sections and the sections of each single sheet spaced by means of carbon leaves, when said sheet is to be written upon, so that true copies can be recorded by merely writing on the uppermost section It is known to provide such books, or pads with the carbons fitted to opposite edges of the sheets so that the carbons can be inserted alternately between each two sections of the folded sheet without being interfered with when the folded sheet is removed. When using such books, however, as hitherto known, the carbon must be applied byhand and the sheet, which is to'be written upon, must firstly be raised and the undermost carbon applied above the innermost section of the sheet, whereupon the next section of the sheet is folded down above said carbon, and the next carbon applied upon the last mentioned section of the sheet, and finally the outermost section of said sheet folded down above the just mentioned carbon-as-' suming the sheet to be triplicate folded. For any other number of folding sections the number of carbons and the manipulations when applying same will be in agreement therewith.

This invention has for its object to shorten the time required for performing the necessary operations and to provide a manifold recording book or pad that will be particu- .larly easy and convenient to use. My 1mproved manifold book or pad can be constructed to suit duplicate, triplicate as well as quadruplicate sheets, and all these three embodiments will be clearly explained below.

I The above mentioned object of invention I obtain by means of stiffening members which act upon the carbons so that the carand its folding sections sufiiciently spaced.

In the accompanying drawings the abovementioned three embodiments are illustrated diagrammatically.

Figure l is a side elevation of a book with triplicate sheets with the uppermost sheet raised for the purpose of applying the carbons between its sections.

Fig. 2 is a plan View of the same book.

Fig. 3 is the same view as in Fig. 1 of a book with quadruplicate sheets.

b Flig. 4 is a plan view of the last mentioned Fig. 5 is a side elevation of a book with duplicate sheetswith the uppermost sheet raised for applying the carbon and Fig. 6 is a similar View of a book with triplicate sheets of a somewhat modified embodiment.

The same reference characters refer to similar parts throughout all the drawings. 7

Referring to the embodiment shown in Figs. 1 and 2, along one edge of a stifi base 1 of card board or similar material there are attached, by meanskof staples 3, the

folded sheets 2 such, that they form a block and each of them can be expanded as shown since only one edge (the left-hand edge in the drawing) is secured to the base 1. At the edge of the base 1, there is attached by means of the same staples 3 one edge of a carbon leaf 5, and at the opposite edge of the base 1 there is secured by means of staples 4, the edge of another carbon leaf 6. The carbons 5 and 6 are attached to the block so that the carbon 5 can be inserted between the first and second sections 2* and 2 of the sheet, and the carbon 6 between the second and third sections 2 and 2 of the same sheet. The sheet 2 is perforated or otherwise weakened adjacent the fixed (lefthand) edge so that, after writing on the uppermost sheet, this sheet can be easily detached and the next sheet exposed for writing. The carbon 5 along the two edges which are at right angles to the fixed edge, is provided with elastic stiffening members 7, such as strips of stifl? card board, and the opposite carbon 6 is provided in the same way with similar elastic stiffening members 8.

section downward, whereafter the carbon 6,

by the influence of its elastic stiflieni-ng members b descends above the next orintermediate section 2, pushing down this section also, so that the outer or righohand section-2 comes down above the carbon 6.

The carbons 5 and 6 will automatically regain the above mentioned starting positions as soon as the upper sheet 2 is detached from the pad and consequently, when raising the 7 next sheet 2 (which after detachment of the first mentioned sheet constitutes the new uppermost sheet), theoperation of the carbons will be as before.

lnFigs. 3 and 4 a book, with quadruplicate folded sheets 2, 2', 2, and 2, is illus trated. The attaching of thesheets and of the two carbons '5 and "6 as well as the ar ranging of the elastic stiffening members 7 and 8 are the same as described in connection with the before-mentionedembodiment.

The pad is here provided also with a third carbon 10, secured'fto the base .1 along the edge .11 of the base by means of staples l i, and this carbon :is also provided with elastic stiffening members 13 which actuate it exactly as before mentioned regarding the elastic stiifenin'g members 7 and 8. lvhen graspingg the-uppermost sheet 2 inthe lower righthand corner 12, the sheetw ill be pulled out and thus all the three carbons moved up- Ward into the positions illustrated in Fig. 3. As shown in Fig. 4 one stiffening member 7 of the carbon 5 is made rather wide so that, "when the carbons stand in their raised position, the carbon 5 is supported against the edge of the third carbon 10-to prevent the carbon-5 from descending before carbon l0.

The carbon 10 moves into the space betv've'e'n the innermost or left hand section 2 and the second section 2*, the carbon '6 into the space between the second section 2 and the third "section 2, and the carbon 5 into space between the third section 2 and the fourth or right hand section 2 In Fig. 5 is shown a book havingdupli eate folded sheets in which both sectionsof the sheet 2 are attached to the base 1 as there is no need to raise more than one sec-- tion for inserting of the carbon. 'Only one carbon is used, which is attached to the-base la't the'edge opposite to the edge where the sheet 2 is fastened, and is provided with elas 'iment. I

If the pads are madeof considerable thickness, that is, include so many sheets that the carbons would be too much worn through use, further "carbons may be arranged inthe same way as before mentioned within the book at suitable distances from the vfirst; mentioned carbons.

Having-thus describedand ascertained my said invention andhow it is to be performed what I claim as new and want to protect by Letters Patent is: I 0

1. In manifold recording books the combination of a base member, a plurality of sheets, bound together and to the base'm'e'm her along one edge, a carbon leaf alsosecured along one edge to said basemembe'r and elastic stiffening members attached to said carbon and rigidly attached to the base member so as to positively and automatically force the carbon leaf into position, as de= scribed. v

2. A manifold-recording bookcornprisi'ng a base member, a plurality of folded shrets bound together and to thebase member along an edge parallel to the folding lines of the sheets, a carbon leaf secured at one edge to the said unit-ed edges, another carbon leaf-secured at one edge to-another edge of the base member, and elastic stiffening members attached to both carbons and idly attached to the base member so as to positively and automatically force the "two carbons into position each between a pair of folding sectionsof the sheets, as described.

A manifoldrecording book comprising a base member, a plurality of folded sheets bound together and to the base member along an edge parallel to the folding lines ofthe sheets, a carbon lea-f secured at one edge to the said united edges, another carbon lleaf secured at its one edge to another edge of the base member, a thirdcarbon leaf secured at oneedge to a "third edge of the base member and elasticstiffening members attached to each of the three carbons and rigidly attached to the base member so as to positively and automatically force the three carbons intoposition each between a pair of folding sections of the sheets, asd'escribe'd.

4. A*man'ifold book compris'ing a base member, a plurality of fold'edsheets bound together and to the vbasevmember, a carbon leaf secured atone edge to 'the'saidunited edges, another 'carbonle'af secured at one edge to another edge of the base member, a

third carbon leaf secured at one edge to a third edge of the base member and elastic stifiening members attached to each of the three carbons and rigidly attached to the base member so as to positively and automatically force thethree carbons into position each between a pair of folding sections of the sheets, the elastic stiffening members on one of the carbons being of sufficient width to be supported against the edge of copies of this patent may be obtained for the carbon which is secured on the adjacent edge of the base member when the carbons are raised, as described.

In testimony whereof'I affix my signature in presence of two witnesses.
