COPYING-BOOK.

SPECIFICATION forming part of Letters Patent No. 576,265, dated February 2, 1897. Application filed September 10, 1896. Serial No. 605,395. (No model.)

To all whom itmay concern.-

Be it known that I, JOHN A. GRAHAM, of Chicago, in the county of Cook, in the State of Illinois, have invented new and useful Improvements in Copying-Books, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to copying-books, and the object is to provide a simple and inexpensivebook that will not require a metal clasp and will allow the carbon-sheet to be easily and quickly removed and another inserted.

To this end my invention consists in the combination, with the original and duplicate leaves, of aback or cover turned over one end of the leaves and bound thereto, said back having slits or apertures in its'turned-over end, a piece provided with a pair of tongues to enter the slits, and the carbon-sheet secured to the piece 3 and my invention consists in certain other combinations of parts hereinafter described, and specifically set forth in the claims.

In the drawings hereto annexed and for1ninga part of this specification, Figure 1 represents an edge view of the book opened. Fig. 2 shows the same closed or folded, as when not in use. Figs. 3 and 4 show similar means for attaching the carbon-sheet to the back of cover, portions only of books being shown. Fig. 5 shows the portion of the book in Fig. 3 with the carbon-sheet removed, and Fig. 6 shows the carbon-sheet with its attaching-piece as they appear when removed from the book.

Referring specifically to the drawings, A indicates the pile of leaves constituting the originals and duplicates, which are bound together at one end by staples a. or other wellknown means passing through the leaves or stubs thereon and the turned-over end of a back B or cover of Manila paper or leather or other suitable material.

The leaves A. may be perforated in any way to allow the separation of the leaves, or the separation of the leaves from the stubs, and the leaves may be folded and secured together by any suitable and well-known means, as these features do not constitute my invention.

My invention consists, as before set forth, in a new and novel means for removably securing the carbon-sheet C to the turned-over end of the cover in position for use, and this I accomplish, as clearly shown in the drawings, by providing the turned-over end of the back B, which lies on the top face of the leaves A, with a pair of apertures or short slits b b, which are preferably parallel with each other and with the side edges of the book, and providing the carbon-sheet C with a flexible piece D of suitable material, having a pair of spurs or tongues c c to enter the slits b b.

The slits b b may be located either inside or outside of the pair of staples a a or other binding means employed to secure the leaves A together and to the cover B. Any suitable apertures will serve in place of the slits shown.

The piece D is secured to the carbon-sheet with glue or other means, and is slitted and cut away at its ends to form tapering tongues c 0, extending in opposite directions and outwardly to enter the apertures or slits b b in the turned-over end of the cover. By these means the carbon-sheet c is securely attached to the book, so that it may be easily and quickly removed if torn or rendered unfit for use by any cause, and another carbon-sheet with its attaching-piece inserted without the use of glue or other cement by the user.

By simply raising the center of the piece D from the book the tongues c a will be removed from the slits, and when a new piece is inserted it is simply curved sufficiently to allow the ends of the tongues to enter the slits, and then it is pressed down fiat upon the book.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a copying-book, the combination with the leaves, of a back secured to the bound end of the leaves and provided with a pair of parallel apertures in one end, a carbon-sheet, and a piece secured to one end of the carbonsheet, and provided with a pair of tongues extending in opposite directions to enter said apertures and hold the piece to the back, as set forth.

2. In a copying-book, the combination with the leaves, of a back secured to the bound end of the leaves, one end of the back being turned over upon the upper side of the leaX'es and having therein a pair of slits lying parallel with each other and with the side edges of the leaves, a carbon-sheet, and a piece secured to the carbon-sheet having a pair of tongues to enter the said slits, as set forth.

In a copying-book, the combination with the leaves, of a back secured to the bound end of the leaves, one end of the back being turned over upon the upper side of the leaves and having therein a pair of apertures, a carhon-sheet, and a flexible piece secured to the end of the carbon-sheet having a pair of tongues extending outwardly in opposite direct-ions to enter the said apertures, as and for the purpose described.

4. In a copying-book, the combination With the original and duplicate leaves and stubs bound together at the stub end by staples, a back having one end turned over and lying upon the upper side of the stub end and bound to the leaves by the said staples, said turned-over end of the back having a pair of slits extending parallel with the side edges of the leaves, a carbon-sheet, and a flexible piece secured to the end of the carbon-sheet having a pair of tapered tongues extending outwardly in opposite directions and entering the said slits, as and for the purpose described.

In testimony whereof I have hereunto signed my name.

JOHN A. GRAHAM.
