7 Claims. (Cl. 116119) This invention relates to an automatic bookmark. The principal objects of this invention are:

First, to provide a bookmark that may be placed in a book and retained therein by the pages of the book to swing downwardly into place or page marking position as the book is closed and swing upwardly out of the book to permit unobstructed reading and turning the pages of the book when the book is opened.

Second, to provide a bookmark that automatically inserts itself between the two pages of a book that are open as the book is closed.

'I hird, to provide a bookmark having the foregoing properties which can be inexpensively manufactured from a single sheet of paper or light cardboard.

Other objects and advantages of the invention will be apparent from a consideration of the following descrip tion and claims. The drawings, of which there is one sheet, illustrate three forms of variations of the bookmark of the invention.

Fig. 1 is a front plan view of a closed book with the bookmark in page marking relation therein.

Fig. 2 is a fragmentary front perspective view of the book in partially opened position and with the bookmark of the invention in the partially inserted position it automatically assumes upon positioning the book in this position.

Fig. 3 is a fragmentary plan view of a single unitary blank or sheet of paper or cardboard from which the bookmark in Figs. 1 and 2 is formed.

Fig. 4 is a fragmentary plan view of the blank shown in Fig. 3 partially folded in erected position and ready to be mounted in a book.

Fig. 5 is a fragmentary plan view of a first modified form of the bookmark also made up from a single sheet of material.

Fig. 6 is a fragmentary plan view of a second modified form of the bookmark.

As shown in Figs. 1 and 2 the bookmark of the invention consists of a front retaining sheet 1 and a back retaining sheet 2 that are inserted in the book 3 just inside the front and back covers thereof respectively and project upwardly beyond the upper edge of the book. A place marking finger 4 consisting of integral hingedly connected arms 55 connects the retaining sheets in spaced relation. In the erected operative position of the bookmark the arms 5, 5 are connected to the retaining sheets 1 and 2 along inclined folds 6, 6' that incline downwardly and rearwardly towards the adjacent inner or rear edges of the retaining sheets. The length of the arms 5, 5' is such that the adjacent edges of the retaining sheets 1 and 2 are spaced from each other to clear the bound edges of the pages of the book.

When the book is closed as in Fig. 1, the place marking finger 4 folds down between the pages of the book that were open when the book was closed. In this position the arms 5, 5' are folded into faced lapped relation and are closed on their connecting fold line 7. As the book is opened, the upper ends of the arms 5, 5' are sepa- 2 rated and the inclined folds 6, 6 raise the arms out from the between the pages of the book and swing them upwardly above the upper edges of the pages: so that the pages may be read and turned in the usual manner.

When the book is again closed the arms 5, 5' and finger 4 descend and find position in the new place in the book. Note that the separating motion of the upper ends of the arms 5, 5 automatically starts the separation of the pages of the book at the marked place in the book so that it is unnecessary for the reader to run his finger down the side of the place marking finger to open the book at the exact marked page.

The form of the bookmark shown in Figs. 1 to 4 is is made from a single sheet or blank 8 of paper or cardboard of suitable weight and stock. The stock should be stilf enough to provide substantial resiliency in the folds 6, 6' and 7 and to give the arms 5, 5' suflicient strength to support their own Weight in swinging into and out of the book. The stock can be plain or decorative and may carry selected printed matter or advertising as indicated at 9, 9. The arms 5, 5' extend across the top of the blank and are separated therefrom by a slit 10. An auxiliary connecting strip 11 connects the retaining sheets 1 and 2 below the arms 5, 5' and is folded in the center as at 12 and at its points of connection to the sheets as at 1313. The fold 12 is convex and the folds 13, 13 are concave as viewedin Fig. 3.

The top portion of the sheet from which the arms.5, 5' are formed is connected to the remainder of the sheet along concave fold lines 14, 14' and is folded forwardly and downwardly over the upper ends of the sheets land 2 and the auxiliary strip 11 prior to using the bookmark. For this reason the fold 7 is concave in Fig. 3 and the folds 6, 6 are convex and inclined towards the fronts of the sheets 1 and 2 because they are reversed when folded down.

The modified form of the bookmark shown in Fig. 5 is the same as that in Figs. 1 to 4 except that the auxiliary connecting strip 11 is omitted. The remaining parts identified by numerals with the suflix (a) therefore perform the same functions as their counter-parts in Figs.

The modified form of the bookmark shown in Fig. 6 is made in two parts and suggests the use of heavier stock. A main blank 15 is notched centrally from the bottom as at 16 and concavely creased or folded as at 17, 17' to form the retaining sheets 18 and 19. A single long strip of stock 20 has concave folds 21, 21' formed near its ends to form attaching legs 22, 22' that are adhesively secured along the outer edges of the sheets 18 and 19. Convex angled folds 23, 23' extend the center of the strip across the top of the main blank and a central convex fold 24 divides the center of the strip into two arms 25, 25' of a marking finger. Desirably, the combined length of the arms 25, 25' between inner ends of the folds 23, 23 is somewhat longer than the distance across the blank 15 between the inner edges of the attaching legs 22, 22' so that the arms 25, 25' and the marking finger bow upwardly or forwardly from the front face of the blank 15 when the marker is in opened flat position.

What is claimed as new is:

l. A bookmark comprising a single integral blank of fold-able paper stock having a central portion cut from its lower edge to form a notch extending to adjacent the top thereof to form front and back retaining sheets, a first connecting strip at the top of said notch connected to said sheets by vertical concave folded con nections and having a vertical convex fold in its midsection, and a second connecting strip connected at its ends to the tops of said sheets and separated by a slit from said first strip and the adjacent inner ends of the tops of said sheets, said second strip having a concave e 2,984,205 I f fold in its mid-section forming the end of a page marking finger consisting of two arms, the ends of said arms having downwardly and outwardly convex folds therein extending to the ends of said slit, said second strip being connected to said sheets along concave fold lines to permit downward folding of the second strip over said first strip.

2.
