MANIFOLDING COPYING-BOOK.

Specification of Letters Patent.

Patented Nov. 30, 1909.

To all whom it may concern:

Be it known that we, CHARLES G. C. \VHYTE, a citizen of the Commonwealth of Australia, residing at Pile street, Marrickville, Sydney, in the State of New South Vales, Commonwealth of Australia, accountant, and ARTHUR RAU, a citizen of the Commonwealth of Australia, residing at No. 53 Terry street, St. Peters, Sydney aforesaid, professional shorthand writer, have invented certain new and useful Improvements in and Relating to Manifold Copying-Books; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

By means of this invention provision is made to further increase the number of reproduced copies of written matter in books hitherto serviceable either for duplicating or triplicating purposes, in which the well known method is adopted of using, in combination with the leaves, an interleaved transfer or copying sheet, whose withdrawal will allow of the combined sheets being detached, while the copying medium is available for further use. Such books have been in use for recording counter sales, orders out, accounts, correspondence, and the like.

By our improved devices hereinafter described with the aid of double faced transfer paper, used either singly or folded, in association with a separate packet of transparent sheets, the number of copies may be increased from two to three, or from two to five, as may be required. This is accomplished by using conjointly the covers of the book, and attaching to their inner sur faces two sets or packets of leaves, so placed in juxtaposition that they will, when the book is closed, be in contact with each other, one set being composed of transparent sheets only, and the other of opaque sheets only, or of opaque sheets (single or folded) in combination with single transparent sheets.

Referring to the drawings which form part of this specification: Figure 1 represents an ordinary duplicating book. Fig. 2 shows covers of a book made suitable for the application of this invention, with index in position on the back cover. Fig. 3 represents a packet of transparent sheets suitable for attachment to a cover as in Fig. 2. Fig. 4 represents a packet of opaque folded sheets as at present in use, fitted with combined clips and hinges for attachment to a cover as in Fig. 2. Fig. 5 represents a packet of combined transparent and single opaque sheets, prepared for attachment to a cover as in Fig. 2, serviceable with a folded trans for sheet to produce additional. copies. Fig. 6 shows the covers as in Fig. 2 combined with packets of leaves as in Figs. 3 and 1-. Fig. 7 shows the covers as in Fig. 2 combined with packets of leaves as in Figs. .3 and 5. Fig. 8 is an edge view of a closed book, showing packets overlying. Fig. 9 shows the hinged packet folded over the transparent packet, to give access to the index. Fig. 10 is a detail of a combined packet clip and eyelet, also serviceable for attachment to the cover. Fig. 11 is a detail of staple for attachment to covers to receive eyelet, also serviceable for attachment to the packet. Fig. 12 shows the method of detaching transparent and folding leaves combined.

The back and front book covers, A and B, are joined by the flexible piece C, which is made of a width to correspond to the combined thickness of the packets D and E, which need not necessarily be of the same thickness because the materials of the two are diiferent. The packet D is composed of ordinary paper sheets, or of such interleaved with transparent sheets or tracing paper interspersed in any desired order and serviceable either as single or folded sheets as may be arranged, to accord with the use of a single piece of double faced copying paper F, which may be bound up with the packet D, or left loose, or to accord with a folded piece of double faced copying paper F F. The packet E is made up wholly of sheets of transparent paper, or tracing paper, lightly secured at the edges E so as to be easily separated. It is intended that these packets shall be secured to their respective covers, so that when the book is opened for use each set will occupy a position distinct from the other, thus either or both sets may the stock of leaves is being exhausted, the thickness of the stub will remain the same. Duplicate books with leaves so constructed are at present provided with devices to retain the stubs in position until the complete exhaustion of the packet, but no provision is made in them for overturning the packet to enable the cover to which it is attached to be exposed to View on the inside, therefore this invention is devised to allow of this being done, because it is essential that the salesmans index G shall be removed from cover B, Fig. l, and transferred to the inside of cover A, Fig. 2, the slit parts A formed in the binding used for the purpose. This index, which is used by the salesman for recording the amount of each sale, is used as frequently as the packet D which overlies it, and in whose leaves the duplicate, triplicate, or multiplicate records are to be made. Ordinarily such leaves are bound in packets with wire fastenings piercing the stub portion D and are rigidly held againstthe surface of the cover by clips and backing pieces.

To render the packet removable a new form of combined staple and eyelet H and combined hook or lug and staple H (Figs. 10 and 11) are provided, to be used in association with the packet D and the cover A. Both devices act as clips or binders by piercing the material and clenching the ends over the surfaces. Three of the combined clips and eyelets H are shown attached to the stubs D in Figs. t and 7, and a similar number of combined clips and staples H are fixed to the cover A, Figs. 2, 6, and 7. The eyelet-s H preferably lie at the surface level of the stub D, as indicated in Figs. 8 and 9. Each hook H is passed through the cor responding eye H, as shown in Fig. 9, but may be readily separated therefrom at will. In said figures the transfer sheet is shown in dotted lines.

In Fig. 9 the packet D is shown overlying the packet of transparent sheets E which rests on the cover B, thus allowing free access to the index G, the staples H standing at a suflicient height to allow of a free movement of eyelets H, and wholly avoiding any movement of the cover A, which is allowed to lie fiat for writing purposes. The flexible part C readily accommodates itself to the changed position of the packet D, which, when thus positioned, has its perforated line D coinciding approximately with the edges E of packet E. This packet is held in position against the cover B by the bottom tongues E inserted in the slits B formed in the cover B, which prevents the packet from being displaced. As an additional precaution against the separation of the leaves forming the packet E, they are held at the corners in housings B formed of stiffened covering material having sufficient spring to engage with the corners of the packet as its thickness diminishes. The individual leaves of packet E may be separated therefrom successively and transferred to the packet- D. A single leaf is thus used with the latter when a single sheet of transfer paper F is available. Two such leaves are thus transferred when a folded sheet F F of transfer paper is used.

The packet of transparent leaves remaining in its position upon cover B, may be folded over, as in Fig. 8, without fear of disarrangement; and it is intended that while the stock of opaque, or combined opaque and transparent, leaves is removed, what remains of the packet E shall fall into the space created by the removal of the leaves of packet D, taking a position against the stub I), and allowing the covers of the book to be closed in a proper manner, the flexible piece C accommodating itself to this arrangement.

It is to be understood that while the combined clip and eyelet H and the combined clip and staple H are shown attached to the stub D and the cover A respectively, the order of attachment may be reversed, in which case the configuration of the respective devices would be as shown dotted in Figs. 10 and 11, the object being to place the eyelet in a vertical position when attached to the cover A, and the staple in a horizontal position when attached to the stub D Either of these devices, when attached to the cover, will not need renewal, but as each stub is removed the fresh packet would have its own attachments to engage with the permanent parts on the cover.

In Figs. i and 6, the double-sided transfer sheet F is shown secured to the stub D to be overlaid upon the lower portion of the folded opaque sheet D. The transparent sheet taken from packet E would be laid thereon, and be kept in position by the upper portion of the folded opaque sheet D, upon which the original writing would be made, as at present. The writing, of course, would be visible through the transparent sheet. here the folded double sided transfer sheet is used, and the transparent sheets are interleaved in the same position as for the single transfer sheet, a further set of copies would be produced.

By the combination of two separate sets or packets of leaves in the same book, provision is made either for producing a series of duplicate copies and a series of triplicate copies, or aseries of triplicate copies only, or, they may be taken alternately in dupli cate and triplicate, but the discontinuance of the taking of triplicate copies would not result in the loss of the transparent sheets, which are still held in reserve for use when required.

In Fig. 12 a triplication of writing is shown effected with a transparent sheet removed from the packet E, the loose sheet and the folding sheet being removed simultaneously, the single transfer sheet F falling naturally into position upon the packet E.
