IMPROVEMENT IN BOOK-MARKS.

Specification forming part of Letters Patent No. 139,936, dated June 17, 1873; application filed August 7, 1871.

particular place in a book, and also a particular line or lines on the page; and consists of a band upon which aretwo clasps which grasp a number of leaves at the top and bottom of the book, respectively, and in one or more pointers which slide upon the hand, all arranged as hereinafter de- 1 scribed.

In the drawings, Figure I is a perspective view of our device in use. Figs. II and III, respectively, are perspective views of a clasp and pointer Fig. IV, an edge View of our device in use, Fig. V, a section of one of the pointers showing the employment of aspring; Fig. VI a similar view with the spring outside; Fig. VII, a plan of the above provided with teeth.

A is a band, preferably made of elastic material, such as rubber, or rubber covered with cotton or silk. B B are two clasps, consisting of the slide b, through which the band A passes, and which are furnished at one endwith teeth b for retaining the clasp on the band, and of the hookb which in use is made to clasp a suitable number of pages. 0 O are pointers, formed of a slide, 0, to fit the band A, and a point, a, projecting out from the slide for the purpose of marking any line or word desired.

In some cases we prefer to provide the pointer O, and even the clasp B, with a small sheet-n1etal spring, d, Fig. VI, which is placed on the slide b, and presses down upon the band to increase the friction and thereby retain the clasp or pointer safe from accidental movement upon the band. The spring 11 may also be arranged on the inside of the clasp, as shown in Fig. V, and provided with teeth it to retain the band shown in Fig. VII.

strain said clasps from being drawn nearer together, but oppose any movement in the other direction by penetrating into the material of the band. After hooking the band in the place desired the pointers can be slid either up or down upon it to the place or places required to be marked, the clasp 0 being made to fit the band so as to be moved without difficulty, but not sufficiently loose to endanger an accidental shifting of position. When it is required to change the band to another part of the same book it is only necessary to stretch it sufficiently to withdraw the hooks b from their hold upon the edge of the leaves, and then after placing the band where required suffer it to contract and hold the hooks firmly clasped upon a suitable number of leaves as before. If desired to transfer the band to a larger book, it is stretched at the point where the clasps B are placed, so as to reduce the thickness of the band sufficiently to permit either of the slides 12 to be drawn toward the end of adapt it to a very considerable range in the size of the books. v

The principal advantage claimed for this device over book-marks heretofore in use is superior convenience. It can be so readily adjusted to any size of book, and the pointers -any number of which can be used upon a band-are so conveniently arranged that taken together they are believed to more nearly answer the requirements of lawyers and others needing such marks than any besigned our names in the presence of two fore ofi'ered to the public. subscribing witnesses.

What we claim as our invention, and desire to secure by Letters Patent, is- HENRY M. WARD.
