.DETACHABLE BOOK-LEAF.

SPECIFICATION forming part of Letters Patent No. 764,701, dated July 12, 1904.

Application filed April 20, 1903. Serial No. 153,482. (No model.)

To a whom it nuty concern:

Be itkn own that I, HENRY IV. Avnns, a citi- Zen of the United States, residing at Los Angeles. in the county of Los Angcles and State of California, have invented a new and useful Detachable Book-Leaf, of which the following is a specification.

The invention relates particularly to leaves which are provided with perforations through which posts, tapes, hooks, or other devices are passed to hold the leaf in place.

One object of my invention is to construct a detachable leaf which is adapted to be used in connection with many forms of fastening devices employed in loose-leaf ledgers.

Leaves for loose-leaf lodgers are frequently torn at the perforations, as the material forming the leaf is usually of paper andthe amount of material between the perforations and the adjacent edge is usually very little. Moreover, those portions of the leaves back of the perforations are pinched together when the book is opened, which prevents a flat opening of the book, the leaves are caused to bend owing to the pressure beyond the perforations, and a considerable space is required in the back of the book to receive these portions of the leaves. Furthermore, these portions of the leaves are unavailable for use except as forming part of the fastening means, as they lie below the posts and it is practically impossible to write anything upon such portions.

The object of the present invention is to construct a leaf with perforations so positioned that the entire leaf lies at one side of the posts, hooks, tapes, &c., and the whole sheet is available for writing upon.

Another object is to reinforce the edge of the leaf along the perforations in such a mannor that it will be practically impossible to tear the leaf away from the fastening devices. In fact, the leaf will tear through the body before the material back of the perforations will tear.

An advantage of the present invention is that the leaf is attached to the fastening devices at points practically on the back or inside edge of the leaf. Therefore the leaves when assembled together in the ledger may be freely turned from one cover to the other without any binding, catching, or disarrangement thereof. In turning a leaf no opposi tion is offered to its turning from the adjacent leaves, as is the case with leaves in which the perforations stand at a distance from the edge.

Another advantage possessed by my improved leaf is that no space is required at the back of the book other than that which is necessarily occupied by the fastening'devices proper.

The accompanying drawings illustrate the invention and form part of the present application.

Referring to the drawings, Figure l is a plan of my improved leaf. Fig. II is an end view of the sheet shown in Fig. I. The reinforcement and that part of, the leaf adjacent thereto have been shown greatly enlarged for clearness. Fig. III is a fragmental view of the inner margin of a leaf, showing another form of reinforcement. Fig. IV is an end view of the modification shown in Fig. III and is greatly enlarged for clearness. is a fragmental view of the inner margin of a leaf, showing a modification in which the openings are in the form of notches.

The invention comprises a new article of manufacture, consisting of a book-leaf proper provided with a selvage formed by folding and gluing down the inner edge thereof and Fig. V

providing said selvage with openings at the edge thereof and a reinforcing material bridging said openings.

By the terms leaf and sheet as used in the specification and claims I refer to a book-leaf proper substantially the entire area of which is adapted to be written on while in its place in a book.

Referring to Fig. I, 1 designates a leaf which is provided with openings, which may be in the form of perforations 2 on notches 2. The edge of the sheet which contains the perforations is folded back upon itself and pasted or glued, and the folded part is fastened to the body of the sheet. ithin the fold and lying preferably along the entire length of the crease is a thread 3. The perforations 2 or notches 2 are punched or cut through both plies of the fold, and the perforations are cut so close to the edge of the fold that the thread bridges the opening-that is to say, closes the notches or completes or assists in completing the continuity of the edge of the perforations. It will be observed that the thread serves to retain the leaf on the attaching-posts or other devices and that its strength. is such that if the leaf were to be pulled away from the posts or attaching devices the sheet forming the leaf would be apt to tear before the thread 3 would break. Fig. 111 shows a tape 4 inserted in the fold, and the perforations are formed through the plies of the fold and the tape. In a leaf constructed as described it is possible to form the perforations very close to the edge. This allows the leaves to be opened flatly without any pinching or scraping together, as is common in leaves with perforations at some distance from the edge. The material or fiber of the thread, while being very strong, is so smallthat there is practically no material on the side of the post opposite the sheet to afford any material opposition in turning the leaf or several leaves or in opening or closing the book. The doubling of the leaf at the perforations also materially strengthens the leaf at that point, and the possibility of tearing or splitting of the sheet at the perforations is obviated.

The book may be constructed for accommodating leaves such as described, and the back may be made much smaller than has heretofore been necessary. Moreover, the entire face of the leaf is available for writing.

What I claim, and desire to secure by Let'- ters Patent of the United States, is

1. As a new article of manufacture, a leaf having a selvage formed by folding and gluing down the inner edge thereof, said selvage having a notch cut thereinto, and a thread extending along the fold of said selvage and bridging said notch.

2. As a new article of manufacture, a leaf having a selvage formed by folding and gluing down the inner edge thereof, said selvage having a notch cut thereinto, and a reinforcing material extending along and within said selvage and bridging said notch.

3. As a new article of manufacture, a leaf having a selvage formed by folding and gluing down the inner edge thereof, said selvage having an opening therethrough, and a thread extending along the fold of said selvage and bridging said opening.

4. As a new article of manufacture, a leaf having a selvage formed by folding and gluing down the inner edge thereof, said selvage having an opening therethrough, and a reinforcing material extending along the fold of said selvage and bridging said opening.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Los Angeles, in the county of Los Angeles and State of California, this 11th day of April, 1903.
