My invention relates to an improvement in bookmarkers.

In the past, many forms of bookmarking devices have been in use. primarily as temporary markers to indicate a page Which is later to be easily found. Many markers, such as markers used in card index files, are provided with protruding edges Which are adapted to receive a number or some other indicating media, such markers being either permanent or of a type which may be secured to a page or card so that it may be removed at a. later date.

In the past, markers for books which are adapted to indicate a page which may be referred l5 to, have been secured Within the book by some clamping device closely associated with the binding of the book.

An object of my invention. is to provide a bookmarker which is adapted to t over a. page to be marked and leave a portion of the marker protruding beyond the edge of the page so that reference may be readily had to a desired page.

A further object of my invention is to provide a bookma-rker which is adapted to be placed over a page so that one strip forming the marker will be on, each side of the page.

A further object of my invention is to provide a bookmarker which has portions thereof extending beyond the edge of a page which is to be marked, these portions being secured to the holding portion of the marker in varying positions relative to its length, so that the protruding edges will not overlap one another.

A further object of my invention is to provide a bockmarker having portions thereof extending beyond the edge of the page which is to be marked, these portions being of varying lengths and secured to the holding portion of the marker so that the holding portion will be positioned at varying distances from the binding of the book to Which several markers have been applied.

A still further object of my invention is to provide a bockmarker which is telescopic so that one given marker may be adjusted to fit pages of different sizes.

A still further obj ect is to provide a bookmarker which is adapted to hold a sheet of reference paper which may be of Water-proof or Washable paper so that the memoranda placed on the sheet may be erased or changed from time to time, these memoranda sheets being removably secured to the bookmarker which is positioned on a given page to be marked.

A still further object of my invention is to provide a bookmarker which is adapted to hold, on

the end thereof which protrudes beyond the edge of the page to be marked, a reversible indicating medium, which indicating medium is adapted to have varying marks on the opposite sides thereof.

I provide two relatively thin strips 2 preferably made of celluloid or thick cellophane, which strips are secured together at both ends 4 thereof by any suitable cement, in which case they will assume the position shown in Figs. 1, 10, 16 and 17, or which may be folded over upon themselves at the ends thereof as shown in Figs. 21 and 22. Between the two end portions 4, the strips 2 are separable so that they may be placed over a page 6 which is to be marked.

Strips 8 of the same material are laterally secured to each of the strips 2 by a suitable cement. These strips 8 extend outwardly from the strips 2, and the outer ends thereof I6 are cemented together so that when the strips 2 are placed over a page 6, the page will also be in position between the strips 8 with the portion I0 thereof extending out past the edge of the page. As shown in Fig. 5, the outer end I0 of the strips 8 may be out away as at I2, so that the reference indicator I4 may be slipped over the end I 0. This reference indicator I4 may be made of any suitable material, for example in varying colors, and having varying reference numbers or letters on either or both sides thereof.

The strips 8, as shown in Fig. 1, may be modified slightly to provide the end portion particularly disclosed in Figs. 6, 7, 8 and 9. In this case the strip 8 is folded over upon itself and is cemented together in close proximity to the slot I6 which is formed in the outer end thereof and is adapted to receive the indicating medium I8.

As shown in Figs. 1 and 2, I have cemented, or otherwise secured, a relatively small piece of washable or waterproof paper 2U, to both of the strips 2 (as shown particularly in Fig. 2), but it will be understood that this piece of Washable paper may or may not be used as on the form of marker which is described above.

In Fig. 10, I have shown a modiiied form of marker which is substantially the same in its general construction, but which is provided with strips 22 placed over the upper portion of the page 24 to be marked, and to which are cemented the laterally extending strips 26 which are provided with a protruding portion 28 on the outer edge thereof. Similar strips 30 are adapted to extend from the lower portion of the page 24 upwardly and are slidably secured to the strips 22 by the straps 32 which are secured to the strips 3D and extend around the strips 22. These straps 32 may be pushed in an upward direction until the upper edges of the straps 32 are abutting against the lateral extending strip 26. The strips 3D may be pulled downwardly until the lower edge of the straps 32 abut against the stops 34 which are cemented to the lower ends of the strips 22. It will be understood that the strips 22 and 3l) are telescopically connected, as shown more particularly in Fig. 13, and are adapted to t one size page while the marker is in its contracted posi tion and to t varying larger sizes of pages as the telescopic strips are stretched outwardly as shown in dotted lines in Figs. 10 and 13.

In Fig. 16, I have shown an ordinary page 36 of a book on which five separate markers have been placed. These markers are made in varying shapes, as illustrated, so that the several markers may be placed on one page of the book and yet the protruding lateral marking strips 3B will not overlap and may be readily seen and selected by the person wishing to refer to the particular page which is marked. It will be understood that these several markers shown in Fig. 16 will be preferably made of a transparent material, so that printed matter on the page 36 may be read without removing the several reference markers.

Markers shown in Fig. 16 are shown all applied to one page, but it will be understood that these markers of varying configuration may be used on different pages, so that the indicating means protruding beyond the edge of the pages will not overlap, and also so that the strips 40, which are placed one on each side oi a page being marked, will not all assume a position of the same relative distance from the binding of the book. These markers shown in Fig. 16 are, generally speaking, the same as the markers shown in Figs. 1 and 2, although the memoranda sheet 20 has been left off of the top of the markers so that more than one marker may be applied to one page without interfering in any way with the other markers applied to that same page.

By means of the varying configuration of these markers, a great many markers may be used in one volume without damaging the binding by expanding the covers too great a distance.

In the form which I have shown in Fig. 17, I have illustrated a telescoping form of marker similar to that shown in Fig. 10, which is provided with two laterally extending strips 42 which are secured to the holding strip 44. This form of marker is adapted to hold a sheet of waterproof or washable paper 46 in position over a page 43 which is to be marked. The memoranda sheet 46 is held in position by the straps 5D which are cemented to the under side of the memoranda sheet 46 and form loops through which the later ally protruding strips 42 may pass to hold the memoranda sheet in position. These memo randa sheets 46 are adapted to be readily removable from the marker shown in Fig. 17 by merely sliding the memoranda sheet off over the ends of the laterally extending strips 42.

While I have shown in Fig. 19, two of these memoranda sheets 46 positioned on opposite sides of a page 48 by being slipped into position over the laterally extending strips 42 on opposite sides of the page, it will be understood that the marker disclosed in Figs. 17, 13, 19, and 20 need not necessarily be provided with laterally extending strips 42 on both sides of the page 48 being marked.

This form of telescoping marker shown in Fig. i7 differs from the form shown in Fig. 10 in that the holding strips extend from the top of the page 46 downwardly and are positioned over the strips 43 which extend upwardly from the bottom of the page At the bottom edges of the strips 44, I provide binding straps 45 .i

which are cemented to the strips 44, and hold the strips 43 in position at the bottom of the strip 44. At the upper end of the strips 43, I provide stops 4l which are cemented to the strips 43 and are adapted to slide with the strips 43 between the strips 44. After the strips 43 have been pulled through their entire length and the markers expanded to t to the largest possible page to which it may be applied, the stops 41 abut against the straps 45 and preclude the marker from being enlarged more. This form of telescoping marker may be pushed into a smaller space than the form disclosed in Fig. l0, because the straps are mounted at the bottom end of the marker and will remain in a xed position relative to the laterally extending strips 42, whereas in Fig. 10, the straps 32 slide on the strips 22 and abut against the laterally extending strip 26 when the marker is in its collapsed position.

ISI)

Figs. 21 and 22 disclose a strip 8 which has been folded over upon itself, this being particularly adapted to be used at the lower end of the marker so that no portion of the marker will extend beyond the bottom edge of a page, and thereby make it impossible or difficult to place a book in a standing position upon a book-shelf after one or more of my marking devices have been applied to the book.

It will be understood that the upper ends of the marker may be made in this form as well as the lower end, in which event one strip t will be folded over upon itself at two points, and the ends of the strip will be secured together at some convenient place by any suitable means.

While I have shown several slightly modified forms which my bookmarker may take, it will be understood that other minor changes may become apparent from time to time as these modied forms of markers are applied to Varying types of books, card-digests and the like, to which they may be applied to afford easy reference to any selected passage, citation, or quotation.
