This invention relates to manifolding books and the like using carbon sheets as a means to provide one or morecopies of an original at one Writing. Two princi al forms of such books are at present emp oyed, one using a single carbon sheet which must be handled andwhich is expected to make a maximum of fifty copies. The principal objections to these books are that the carbon leaf must be handled, and that the copies obtained are not uniformly legible. The other form of book employs a coating of carbon on the back of each original sheet. The principal objections to this form are that the clerk and in many cases the customer each have to handle a carbon coated sheet, and such sheets cannotbe enclosed with easily soiled goods.

/ In the present invention my object is to devise a form of book (a) in which the necessity an of handlii'lg a carbon sheet each time the book is used is avoided, (b) which may be so used, that at no time is a carbonized surface exposed for contact Willh the users hands, (0) which will enable duplicates of the originals an of uniform legibility to be produced, (01) which will provide in bound form, numerical- 1y arranged, copies of all entries made, so that any subsequent alterations made in original sheets may be readily detected, (e) and so which, as a plurality ofcarbon sheets are employed, in the book, the used carbon sheets are retained in the book in such a manner that they require no handling and are protected from damage or disfigurement of the impression made thereon 'durin use.

Further objects will ereinafter appear from the detailed description and illustration of the invention.

\ Briefly my construction is as follows: The book is made up of a plurality of units, bound in together, each comprising a duplicate sheet, a carbonsheet, and an original sheet united along one edge to the duplicatesheet and folded over the carbon sheet. 3

The book is provided witha'cover having a stop sheet connected with the back adapted to be folded into thebook. The originals and duplicates, and preferably the carbon sheets, are consecutivel numbered from the back to the front of the 00k, which is thus used from the back to the front, the stop sheet being interposed between a unit to be used and over nal, and sometimes the duplicate, is torn out,

the stop sheet is hinged out of the book and then swung back into place over the used carbon sheet, or carbon sheet and duplicate, remaining in the book.

The invention is hereinafter more fully described, and is illustrated in the accompanying drawings in which Fig. 1 is a perspective view of one unit of the book comprising an original sheet, adupli cate sheet and a carbon sheet;

Fig. 2 a perspective view of a book constructed in accordance with my invention as it appears when ready for the making of an entry on an original sheet;

Fig. 3 a similar view showing the original and duplicate in position to be torn ofi Fig. 4 a similar View, after the original and duplicate have been torn oflflshowing the stop sheet lifted to allow the carbon sheet to drop; and r Fig. 5 a similar View showing the book with the original and duplicate removed and the stop sheet turned in over the carbon leaf ready for the drawing down of a new unit.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

Referring particularly to Fig. 1 of the drawings, it will'be seen that each manifolding unit comprises a duplicate sheet 1 provided with a long stub 2, a carbon sheet- 3 superimposed thereon, and also provided with a long stub 5, and an original sheet 4 united to the free end of the duplicate sheet and normally overlying the carbon sheet.

The stub of the carbon sheet is non-carbonized, as shown, which facilitates the consecutive numbering of these sheets and gives a clean top for handling, if necessary, and lessens the liability, if the carbon sheet be handled, of defacing the record thereon. The opposite end of the carbon sheet is also formed with a non-carbonized margin 6 which similarly facilitates handling if at any time handling be necessary.

By means of the stubs 2 and 5 a plurality of the manifolding units are bound together to form a book, as shown in Figs. 2 to 5 of the drawings.

'The book is provided with a cover, which includes, at least, a back 7, and a portion 8 bound to the stub of the book. It will usually also include a front 9. A stop sheet 10 is connected, preferably integrally, with the free end of the back 7 ,so that it may be used as hereinafter described. The originals and duplicates will be printed, as usual, according to the requirements of the purchaser, and will be nun'ibered consecutively from the back to the front of the book. Corresponding numbers will usually appear on the carbon sheets, preferably by being imprinted on the stubs Bhereinbefore referred to. The stop sheet also acts as a record sheet upon which a summary of the sales may be entered. Perforations or other lines of weakness will usually be employed to facilitate the separation of the originals from the duplicates and separation of the duplicates from-their stubs.

As a separate carbon sheet is provided for each manifolding unit, I find it desirable, in order to avoid making the book too bulky, to use for the carbon sheets a very thin, cheap paper having a very light coating of carbon applied to the same. Such carbon sheets possess the further advantage that, owing to their fragile nature itis impossible to make alterations therein without detection. These sheets thus serve as a permanent reliable record of all entries made in the book.

The mode of operation will i .ually be substantially as follows. The manifolding units are thrown back over the front cover, as shown in Fig. 2. The long stubs employed permit this to be done so that the book will lie flat on its supporting surface. The stop sheet 10, then rests on the back 7. The first manifolding unit or set of leaves (1, 3, 4), Which is uppermost when the book is so opened, is then pulled towards the user and dropped on the stop sheet 10'. A record or memorandum is then made on the original sheet from which, through the medium of the carbon sheet 3, a copy is made on the duplicate sheet 1. A legible impression is also formed on the carbon sheet 3. The original may be then torn from the duplicate, or the original and duplicate torn together from the stub and subsequently separated. The removal of the sheets 1 and 4 leaves the carbon sheet resting on the stop sheet 10. The stop sheet 10 is then lifted (see Fig. 4), allowing the carbon sheet 3 to drop down on the back 7 This operation, it will be noted, does not require any handling of the carbon sheet. The stop sheet is then allowed to drop on the carbon sheet and the book is then in position for entering the record of the sale on the printed form on the stop sheet, and leaves the book, if subsequently closed, in shape for convenient opening at the right place for making the next record, which involves merely a. repetition of the steps just described.

If the duplicates are left in the book the non-carbonized margin of the carbon sheet facilitates the raising of the carbon sheet to obtain access to an underlying duplicate without soiling the fingers.

In case the record made, on a given unit, has not been completed or it is required to be referred to later, the whole unit may be dropped beneath the stop sheet and lifted out for completion or examination at any subsequent time without touching any carbon surface. The record, when the unit is so held under the stop sheet, is kept safe from any accidental defacement.

During all these operations, it will be seen that the carbonized surfaces are at no time exposed and at no time is it necessary for the user to handle the carbonized surfaces.

From the above description it will be seen that the invention provides a simple and practicable counter check book which will satisfactorily attain the objects of my invention asset out in this specification.

What I claim as my invention is:

A manifolding book comprising a back, a plurality of manifolding units, each unit comprising a carbon sheet and a detachable duplicate sheet bound to the back and an original sheet united to the duplicate sheet along one edge with its opposite edge free and folded over the carbon sheet, and a stop sheet united to the back and foldable over the used carbon sheets and between the same and the next duplicate sheet and protecting the record on the used carbon sheets aganist mutilation While making subsequent entries.

Signed at Toronto this 11th day of December, 1928.
