SPECIFICATION forming part of Letters Patent No. 448,470, dated March 17, 1891.

Application filed June 6, 1890. Serial Nasfi lAZ l. (No model.)

To all whom it may con-corn:

Be it known that I, CLARK M. Bnnsrow, a citizen of the United States, residing at Bryan, in the county of Williams and State of Ohio, have invented certain new and useful Improvements in Book-\Iarks; and I do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to bookmarks, and has for its object to construct a book-mark which will not only most conveniently and satisfactorily serve the purpose, but which will at the same time be inexpensive to produce, and which is adapted to receive advertising matter.

To the accomplishment of such purposes the invention consists in the construction and the combination of parts hereinafter particularly described and claimed, reference being had to the accompanying drawings, forming part hereof, and in which- Figure 1 is a plan View of one form of the mark with the unfolded position of the flaps shown in dotted lines. Fig. 2 is a similar view of a modified form. Fig. 3 is a perspective showing the flaps distended. Fig. at is a perspective of the mark made separate from the main body. Fig. 5 shows such modified form attached to the main body. Fig. 6 is a perspective view of a book with the mark applied thereto.

In the drawings, the letter A designates the main body of the mark, which may constitute a business or professional card, a leaf, or the outside sheet or cover to a pamphlet or other leaflet of any desired dimensions adapted to be inserted between the leaves of a book. This sheet, card, or base is provided with a pocket or flange B, formed integrally with the base or separately therefrom and secured by some adhesive substance or otherwise to the base at a corner thereof. The preferred method is to form it integrally with the base or body by providing the same with side and end projections or flaps a and Z) at or adjacent to the corner and turning the same down upon the base or body and cementing the two turned-down portions together along the edges indicated by the dotted lines o and cl in Fig. 1. The position of these proj ections or flaps before they are turned down is indicated by the dotted lines e and f in Fig. l.

Instead of having the flaps project from both the end and side of the base, they may project from only one of said partsfor illustration, as indicated by dotted lines in Fig. 2 of the drawings. Inthat form the projecting flaps a and b will project so as to form a right angle to each other, which, when folded down upon the body or base, and joined thereto by cementing along the edge of the base, will form a pooketsimilar tothe first-described construction. It is preferred to form the flap a in the form illustrated in Fig. 2, with an extension or piece as indicated by dotted lines in that figure, so that it may be folded down over the edge of the base and be secured to the other face of the base, as it thereby makes a stronger and more durable construction. Such extension, however, may be omitted.

There have been shown and particularly described two preferred constructions; but it is not meant to be limited thereto, as the pockets may be formed in many different ways and out of flaps of various forms. The flaps also may be of any desired configuration or design, and instead of being formed integrally with the base or body may be made separate therefrom, as illustrated in Fig. 4, and cemented or otherwise attached thereto, as illustrated in Fig. 5.

In using the mark the body of it is inserted between the leaves of a book, and the corners of a number of the leaves inserted in the pocket or recess formed by the turned-down flaps. As a page is finished it is taken by the free corner and turned over the confined corner, easily leaving the pocket or recess, while the other leaves are retained by the pocket. hen the book is closed, the mark remains in place, holding the leaves and indicating the pages not read and the place where the reading was suspended.

This mark will be found a great convenience, andv will avoid the necessity of changing the mark from one place to another every time the book is closed, as will be apparent from the foregoing description. It can also be used as a means for advertising, as any matter desired can be printed on the body of the mark, as indicated in Fig. 1, or on the flap, as indicated in Fig. 5, and the mark being preserved on account of its convenience and usefulness the advertising matter is always presented to the attention of the holder of the mark.

Having described my invention and set forth its merits, what I claim is 1. A-book-mark comprising a base A, provided with a pocket or recess at a corner thereof along the two edges of the base, which extend at right angles to each other, said pocket serving to receive a number of leaves and the base affording a broad contact-surface to hold the pocket in place, substantially as and for the purposes set'forth.

2. A book-mark comprising a base or body designed to be inserted between the leaves of a book and provided with a flap folded to form a recess to receive a number of the leaves to hold them and indicate where the reading was suspended, substantially as and for the purposes set forth.

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