Specification of Letters Patent.

Patented Mar. se, raie.

Application filed March 4, 1915. Serial No. 11,977. l

To all 'whom it may concern Be it known that I, REGINALD H. CAMP- BELL, a citizen of the United States, and a resident of the city of Kankakee, in the county of Kankakee and State of illinois, have invented certain n-ew and useful Improvements in Book-Markers; and Iv do hereby declare that the following 1s av full,

clear, and exact description of the same,

reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

- This invention relates to an improved type of book marker wherein a plurality of marking devices are adjustably associated with retaining means toafforda convenient means of marking the different pages in the book desired for reference as well Vas the particular line or paragraph on a page referred to. p

It is an object therefore of this invention to construct a book marking device consisting of inserts adapted to be placed between the pages of a book and detachably retained in position by means disposed at each end of the book, and with marking devices movably secured to each of said inserts to serve as a finding tab at the outer edge of the book and also afford a means of indicating particular line upon a page. Y

. itis also an object of this invention to construct book marking device of fieXible nature to permit distortion thereof Vwith bending of the leaves of the book, and with flexible retaining means attachable at each end of the book to hold the same at all times, in proper position in the book.

it is furthermore an importantobject of this invention to provide a book marking device embracing a plurality of inserts attached at each end of the book upon resilient spring members and readily removable therefrom and provided with movable indicating means adapted to be adjusted to any desired position between the pages to alford a finding tab at the edge of the book, the entire device being removable as a whole from the book Without requiring disassembly of any of the parts.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings: Figure l is a plan view of a book in open position shown equipped with a device embodying the principles of 'taining means of the device.

my invention. Fig. 2 is a fragmentary end view thereof. Fig. 3 is a fragmentary plan view of one of the inserts and indicating elements shown detached from the retaining means and from the book. Fig. 1i is a. view similar to Fig. 2, illustrating the book bent open and showing the flexibility of the parts. Fig. 5 is a detail of one of the spring snap rings used in connection with the re- Fig. 6 is a fragmentary section taken on line Gw of Fig. 3. Fig. 7 is a side edge view of the end of one of the indicating elements. Fig. 8

is a fragmentary plan view illustrating a modified means of connecting an indicating element to a page insert. Fig. 9 is a fragmentary section taken on line 9 9 of Fig. S.

As shown in the drawings, the covers of a book are denoted by the reference numorals l, and the pages by the reference numerals 2, the covers 1, being flexible to permit bending thereof, as clearly shown in Fig. 4f. Disposed between certain pages of the book to which reference is to be made, are marking or insert strips of flexible material such as transparent Celluloid, each denoted by the reference numeral 3, and each having at its ends apertures t, therethrough. As clearly shown in Figs. l, 2, and 1i, said inserts 8, are placed between the pages 2, close to the back or binding of the book, and where a number are used small coiled flexible springs 5, are provided at each end of the book which engage through the apertures 4, ofthe inserts to retain any one thereof from displacement when the book is opened to a particular page, such as shown in Figs. l and 4L, at which such an insert is disposed. A fine chain 6, having a closed eye 7, at one end thereof engaged through a loop at one end of the spring 5, is provided, and at its other end has a spring latch ring 8, which may be opened for disengagement from the loop at the other end of the spring 5, when it is desired to attach or detach one of the inserts 3, to or from said spring.

Movably mounted upon each of the page marker inserts 3, are indicating elements 9, one end of which, as clearly shown in Fig. 6,

` is folded over upon itself to afford a loop for engagement around the marker insert 3. At the other end of each of said indicating elements 9, which are preferably of transparent flexible Celluloid, is an indicating tab, which is formed by dipping the end of the element in an opaque celluloid solution to forni a coating ll0, thereon, which is properly lettered with a character, such as illustrated infull and in dotted lines in F ig. 3, as 17 and thereafter being dipped in a transparent Celluloid solution to form a protective coating ll, thereover.

In Figs. S and 9, I have illustrated a modified means of attaching an indicating element, denoted by the reference numeral 12, to al page marking insert 3, and for this purpose said indicating element 12, is provided With'aiienlarged rounded end 13, having a slot therethrough permitting the ieXible indicating element 12, to be folded around the insert 3, and inserted through.

the slot, thus forming a slip loop around said insert, which permits detachment of the indicating element therefrom, as Well as a' sliding movement thereon. Y

Ifdesireda memorandum card lll, maybe attached upon'anyrone or all of the indicating elements of the device' in a manner illustrated in Fig.l l, bymerely cutting slots in the card and engaging the card upon the indicating element, and the card may then be lettered on both sides thereof to afford reference ineniorandunis to the reader for either of the pages of the twoshe'ets between which said indicating element is disposed.

rIhe operation is as 'follows Inasmuchas there is a retaining means at each end of the book the page marking inserts 3, may be first attached upon one of the springs 5, and then inserted between the pi'oper. pages of theV Vbook to rwhich reference is to be subsequently made.Y The other spring 5, is then inserted through the apertures 4, at the other end of Y the marking strip inserts, the snap ringY 8,

being detached-from the end'of 'the spring 5, for the purpose. After the inserts have been engaged on said latter spring, thesnap ring 8, is again engaged upon the end'of theV Y springg-so that there is no possibility ofthe Vwith the Yin arking insert. j Y ments constituting the device are flexible, so

,i thatthere is no possibility of injuring the i retaining means slipping out of engagement All of the eleed thereon at the outer end of said element aifords a finding means, permitting the reader to turn immediately to the page desired. Y

I ain-aware that various details of construction may be varied through a Wide range Without departing from the principles of this invention, and I therefore do not purpose limiting the. patent granted other-Q Wise than necessitated'by the prior art.

I claim as my inventionz; 1 ,Y Y l. In a book marking device of the.. class described, a pluralityV of flexible Vpage inserts having apertures in each end thereof,

coiled springs extending through said aptures, and detachable means on said springs Y to retain them in operative position.

2. In a device of the classfdescribed, iii-- serts adapted to be ,placed between the pages of a book and having apertures in the end thereof,'coiled springs inserted through the Y apertures of said-inserts, one of said'mem-"jfV bers disposed at eachend of the book, andV detachable means thereon to retain'said inserts in operative position in said members. 3. In a'device of the class described, the

combination with a book, of marking means therefor comprisinga plurality of adjust-V able strips insertible between the pages of;

the'book, and coiled springs,one disposed at `each endf of the bookandconnectedto the projecting ends of said strips Vto maintain the saine associated with thebook. I
