INDEXING BOOK-MARK.

SPECIFICATION forming part of Letters Patent No. 399,417, dated March 12, 1889.

Application filed October 8, 1888. Serial No, 287,492. (No model.)

To (r71 117mm it may (once/'11 Be it known that l, .IoHN Lawn, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful .lmprovements in Book-illarks or Indicators, of which the following is a specification.

My invention relates to book-marks or indicators, the object being to provide a device of this class which will be adapted to indicate page of a book, and also to furnish means whereby the book may be readily opened at the indicated place.

The device may also have printed or stamped upon it a figure or letter which will serve as a serial index to indicate the order in which the references are to be utilized.

I am aware that it is not new to provide a device of this nature; but the present invention is designed to accomplish the purpose in a more efficient manner and by a simpler and cheaper device.

Referring to the accompanying drawings, Figure 1 represents a view of the metal blank as it is stamped from the sheet. Fig. 2 represents a view of the device finished, and Fig. 3 shows the position of the device upon a book.

The device, as shown in lrig. 1, is stamped 1 from sheet n1etal-pretcral l v brass. At one ftered consecutively, a particular paragraph or line upon a certain end it is formed into an index or pointer, (1, in the shape of a hand, while from the opposite end a tail piece, Z), of anysuitable form,

extends.

Midway between these two eXten- I sions the blank is enlarged con siderabl y and has cut in it a U-shaped kert, the position of f grippwl thereby. The clip is pushed over the leaf until the bend meets the edge of same. \Yhen in this position. the straight flap (1 extends beyond the leaves of the book and may be used as a handle in opening the book at the place indicated. The flap (2 also serves a further important function. The marks will be sold in sctssa v of about twelve each. They will be numbered or letthe character being stamped, printed, or pasted upon the flap in an 3' desired manner. They ma then be distinguished from one another when several are used together on the same or adjacent leaves.

of a book.

There are many uses for this kind of a device when designed in proper manner. Twenty-six or more of them maybe provided with the letters of the alphabet, and the set then used on a dictionary or directory to indicate where the respective lists begin and end.

Having described my invention, I elainr 1. A book-mark orindicator formed of one piece of metal folded over between its extremities upon itself so as to form a pair of spring lips, one of said lips having a backward ex tension or flap, for the purpose described.

9. A book-mark or indicator formed ofa single piece of metal folded over between its extremities upon itsell, thus forming two lips which spring toward each other, one of said lips bein made up of two extensions, said extensions being located on opposite sides of the fold, substantially as described.

3. A book-mark or indicator formed of one piece of metal folded over between its extremities so as to form a pair of spring-lips,

The blank is one of said lips having a backward extension or flap provided with a letter, figure, orother indicating character.

In witness whereof I have hereunto al'lixed my name in the presence of two subscribing witnesses.

JOHN LANE.
