SPECIFICATION forming part of Letters Patent No. 538,706, dated May 7, 1895.

Application filed April 30, 1894? Serial No. 509,450., (No model.)

To all whom it may concern.-

Be itknown that I, DANIEL SnXToN, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Book-Marks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, formin g a part hereof. 4

My invention relates to that class of devices which are employed to mark or designate in a book the place or page at which it is desired to reopen the book, and the object of the invention is to produce abook-mark which'will not be accidentally displaced from position;

which may be easily and expeditiously placed in or removed from position, and which is simple, and inexpensive of manufacture.

With these objects in View, the invention consists in the peculiar construction of the mark and its arrangement relative to abook, as hereinafter described and claimed.

In order that the invention may be fully understood, reference is to be had to the accompanying drawings, in which- Figure 1 ,is a perspective view of an open book, showing one of the leaves thereof carrying, in operative position, abook-mark constructed in accordance with my invention. Fig. 2 is a perspective View of the book in its closed position, showing the handle portion of the book-mark projecting beyond the front margin of the leaves of the book. Fig. 3 is a perspective view, enlarged, of the mark shown in Figs. 1 and 2. Fig.4.isad'etail perspective view of a modified form of the book-mark. Fig. 5 is a perspective view of the same arranged in operative position relative to one of the leaves of the book. Fig. 6. is a perspective View of a still further modified form of book-mark and showing the same in 0perative position relative to one of the leaves of a book.

In the drawings, A, designates a book-mark comprising the similar sides or sections a, b. In the blank, these sections are at "right angles. to each other, the section a, occupying the positionshown in full lines, and the section I), occupying the position shown in dotted lines, and these sections are bent at their point of intersection one against the other, and have their outer ends glued or otherwise rigidly secured together, as shown at 0, so as to form a loop or space, d, between said sections, and the opposite ends of said sections and also of the space therebetween converge; these converging ends extending at right angles to each other.

In operation, when desiring to mark a certain page or place in a book so as to be able to reopen the same at the same page or place, the particular leaf is raised, and a corner thereof inserted into the space d, of said bookmark at its widest margin, and said bookmark is slipped inward upon said page until the front margin and end margin of the leaf come in contact with the converging ends of said space, and thus limit the inward movement of the book-mark, which snugly embraces said leaf. The book may now be closed, as shown in Fig. 2, and the ends of the bookmark, projecting slightly beyond the margins of the leaves of the book, will designate at all times the proper place to reopen the book. If found desirable, one of the ends of the bookmark, preferably the one projecting beyond the front margin of the leaves of the book, is extended outwardly a suitable distance, as shown at e, and, being of sufficient strength, may be used as a handle whereby the book may be opened.

Referring to Fig. 4, a modification is shown which embodies the essential features of the book-mark previously described, but which may be found better adapted to books of small size. In said figure, D designates a pair of similar sections, which are provided at their outer ends with the margins E, E, extending at right angles to the side margins of said sections D, and these sectionsD are joined at their outer ends by the converging portions F to the opposite ends of the margins E, so as to form a loop or space G.

In operation, one corner of a leaf Hof a book is inserted between the sections D, D, and the book-mark is then moved inward until the margin of the leaf projects through the loop or space G, and the front and end margins of the leaf come in contact with the inner side of the converging portions F, which join the sections D, D, together, and limit the inward movement of said book-mark. It will be apparent to remove this book-mark, and also the mark first described, from position that it must be pulled obliquely outward from the corner of the leaf.

Referring to Fig. 6, a still further modification is shown, and this book-mark comprises the rectangular sections I, I, which are joined together at their outer margins, as shown at J and K, so as to form a rectangular space L between said sections 1, I, and into this space, in the practical application of the mark to a book, one of the corners of the leaf is inserted until the side and adjacent end margins of the leaf come in contact with the closed ends J and K of the space L.

From the above description, it will be apparent that I have produced a book-mark which may be made of paper, linen, or of any other suitable material, and which will reliably mark and designate at all times the place at which the book is to be reopened. Furthermore, a book-mark which is extremely simple and inexpensive of construction, which will not be accidentally displaced when opening the book carelessly or in a hurry, and which, by occupying a space between the leaves and at a distance from their inner margins, will not injure the book, which is often done by the insertion of cards or other matter between the leaves and adjacent to their point of junction.

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

A book-mark, comprising a section a, having its end-margins extending at right-anglesto each other, a section I), having its end-margins at right-angles to each other and joined at one end-margin to the corresponding endmargin of the said section a, and joined at some distance from its opposite end to the other section a, at a corresponding distance from its end to form the handle-portion e, and the loop d, through which the corner of a single book-leaf is adapted to project, substantially as set forth.

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