BOOK-MARKING DEV ICE.

Specification of Letters Patent.

Patented Apr. it), 1917.

Application filed. May 6, 1915. 7 Serial No: 26,418.

To all whom it may concern-:-

Be it known that I, Gnovnn PERRY, a citizen of the United States of America, and resident of Chicago, Cook county, Illinois, have invented acertain new and useful Improvement in Book-Marking Devices, of which the following is a specification.

My invention relates to book marking devices, and more particularly to devices of the kind that have one or more marking members, each of which has an index projecting beyond the leaves, and all of which are controlled by a common element to hold them in place.

Among the objects of my invention are the following: To provide a device of the above character, the marking members of which are adapted each to be removed without the necessity of disturbing the others, or of removing the common member; to provide a device by means of which it is possible to turn quickly to any section of the book previously marked without having to handle the leaves, the markers of which will remain securely in place whether the book is closed or open and notwithstanding the fact that the members are individually removable; to provide a device which may be easily and quickly attached to and detached from a book without in any way marring the same; to provide a device of the above character. which is automatically adjustable to books of different sizes, the marking elements of which are light and thin and yet with suflicient rigidity to enable them to be satisfactorily pressed into operative position in engagement with the flexible common holding member; to provide marking devices having peculiarly and suitably shaped terminals for facilitating the operation of placing them in position and of removing them; and to pro vide details of improvement tending to increase the efficiency and serviceability of a book marker of the above character. The means for accomplishing the foregoing are hereinafter set forth and claimed.

Referring to the accompanying drawing,

Figure 1 is a view of the book as it would appear when opened on a table, showing the book mark with a number of marking memhere in position.

Fig. 2 is a view of the book on end giving a clearer view of the device.

Fig. 3 shows detail means for holding the common member in position.

Fig. a is an enlarged view of one of the marking members.

Referring more in detail to the drawings it will be seen that the marker A (Fig. l) is T shaped, and that on the end of the arm that extends to the right there is a number 14 for identifying that particular marker. number maybe substituted by a letter or any other suitable character, and may be remov able or adapted to be erased. The other limb of the marker which is at right angles is provided at the lgwer terminal with a slanting point B, and a notch C. The upper end is provided with a point D and a notch E having a wider trough than the notch G. Referring to the other figures there is shown a common element F, which may be made of any suitable elastic material. This elastic element can be slipped over the leaves of the book as clearly indicated, for example, in Fig. 2, and because of this elastic quality the book may be opened or closed without any difficulty and without any danger of the clastic coming 0H, since when the book is open there is a tendency, as indicated in Fig. 1, of the elastic to crawl in the direction of the hinge of the book. After the elastic is once in position, if it is desired to mark any particular page, the marker 1 f (Fig. t) may be taken up and inserted in position, as shown in Fig. 1 with the notch C engaging the lower side of the elastic and the notch E engaging the upper part of the elastic. The notch C since it is V shaped in form, insures that the markers A are all held in the same relative position nconstantly, that is, if the marker A, for example, is accidentally pulled either one way or the other, the tension of the elastic will always tend to pull the marker back into position.

Referring to the drawings it will be seen hat I provide a strip or string K, linked with the band F, at the lower end of the book for the purpose of raising the elastic to latch and unlatch the markers. This loop acts as a latch string, and may be slid along the band to any point desired. However, it will be understood that instead of the loop an ordinary string tied to the band might also be used instead, if desired. I have designed the markers (Fig. l) with a sharp, upper end so that the upper end may be easily shoved into position under the band. The lower end, however, I have made rather blunt in order that the lower end may not This I be so easily inserted in place in this manner. .After'the upper end is latched into position the lower end is allowed to rest on the band; then by pulling the latch string the band is drawn out and stretched over the blunt end and allowed to drop into the notch. The object in this arrangement is to avoid the necessity of using the marker to stretch the band, in order to shove the lower end under the band in a manner similar to the upper end. When this is done there is a tendency to warp and distort the band, making it necessary to run the hand over the marker and consequently over the page to straighten it out. The object, therefore, in making the lower'end blunt is to discourage this method of introducing the marker in place.

It will be seen that this elastic can be held in position if it should be so desired by pro-- viding clips G, which project over the edges of the book a short distance. These clips 7 may be riveted or glued to the page or fastened 1n any sultable manner, or the elastic might be held in place by suitable straps H, which also may be secured to the book in a similar suitable manner.

It will be seen, therefore, that I have de vised a highly improved book mark which is compact and convenient, and which p0ssesses all of the advantages already enumerated.

WhatI claim as my invention is:

1. In combination, a plurality of leaves, a flexible member embracing said leaves and a marker element, said marker provided with a tapering end for raising the flexible member whereby the marker may be insert-.

the flexible member whereby the marker may be inserted thereunder and deposited between said leaves, each marker also provided with a notch behind the tapering section for latching the marker in place under the flexible member whereby all the markers may be lined up.

3. In combination, a plurality of leaves, a flexible member embracing said leaves, a plurality of strip marker elements, each marker provided with a tapering end for raising the flexible member whereby the marker may be inserted thereunder and deposited between said leaves, each marker also provided witha notch behind the tapering section for latching the marker in place under the flexible member, whereby all the markers may be lined up and each marker provided also with a notch near the other end whereby the marker may be latched at the other end by said flexible member.

4-. In combination, a plurality of leaves, a flexible member embracing said leaves and a plurality of marker elements, each marker provided with a tapering end for raising the flexible member whereby the marker may be inserted thereunder and deposited between said leaves, each marker also provided with a notch behind the tapering section for latching the marker in place under the flexible member, whereby all the markers may be lined up and a sliding latch left permanently looped around the flexible member for unlatching the marker elements.

5. A strip boolemarker to go between the leaves of a book, a notch near the end of the strip, said notch having a side at an angle to the length of the strip, a flexible member across the leaves near the binding for en-- gagement with said notch, said side acting as a stop for said flexible member, a tapering point for said strip whereby the ends of the strip having said notch may be inserted under the flexible member to latch the strip in position, and a notch near the other end of the strip having a side at an angle with the length of the strip, said flexible member extending across the other end of the book for engagement with said second notch, said side of said second notch acting as a step for said flexible member.

Signed by me at Chicago, Illinois, this 21st day of April, 1915.
