BYMMLLJ I ATTORNEY Patented Aug. 6, 1946 UNITED STATES PATENT OFFICE BOOKMARK Francis L. Singer, Jr., Peekskill, N. Y.

Application August 26, 1944, Serial No. 551,391

6 Claims. 1

My invention relates to book or page markers.

An object of my invention is a book marker which will automatically indicate or mark the page reached by the reader, slipping over the edge of each page when the same is turned and thereby assuming the correct marking position on the following page.

Further objects are a book marker which is prevented from being lost or mislaid, which can be affixed to a book permanently, which can be concealed in the book without any part of the book marker protruding beyond the books edges, and which will neither change the appearance nor the height, nor the width of the book when the latter is stored away.

Other objects are a book marker that can be easily brought from a concealed condition adapted for storage or shipping into a position adapted for use, that can be folded and unfolded, and that does not interfere with the reading of anything printed on the marked page wherever such print may be on the page.

Still another object is a book marker adapted to show advertisements which are visible throughout the reading of the book.

Still further objects and advantages will appear from the following description of an exemplifying embodiment of my invention, from the appended claims, and from the drawing in which:

Fig. 1 shows a front elevation of a book marker embodying my invention and affixed to a page of a book, this page and the neighboring page being shown broken off.

Fig. 2 shows a side elevation of the same embodiment seen from the right side in Fig. 1, the thickness of the parts being shown exaggerated for the sake of clearer representation.

Fig. 3 shows a perspective view of an open book provided with the book marker shown in Figs. 1 and 2, the book marker being shown in the position of use.

Fig. 4 shows a view corresponding to the view shown in Fig. 1, except that the book marker is shown folded into the position of storage.

Referring to the drawing, numeral l indicates a book and numeral 2 that page of this book to which the book marker is afiixed according to my invention. Preferably, the page 2 is any one of those empty pages which are usually provided in a book behind the last printed page.

The book marker consists of a base leaf or plate 3 and of a leaf-like flap 4 which are connected to each other, preferably at their upper ends. The base leaf 3 is foldable and has a part 5 preferably forming the lower rim of this leaf and 2 divided from the remaining part of the leaf by a crease or folding line 6, The back side of the part 5 may be gummed or covered with an adhesive layer, or may be affixed to the page 2 by any other suitable means.

The flap 4 may form an integral part of the base leaf or may comprise a part or rim 1 which is so affixed to a part of the surface of the base leaf 3 that the part I ispermanently held close to this surface part of the base leaf whereby the flap 4 tends to remain in or to return into a position parallel and adjacent to the leaf 3. From the rim 1, the remaining part of the flap 4 extends downward about parallel to the base leaf 3, but spaceable therefrom, the flap being sufficiently resilient to be bent in the direction of the arrow 8 in Fig. 2. The main part of the flap overlies the foldable part of the leaf 3. Preferably, a portion of the flap extends beyond the lateral edge 9 of the leaf 3 and permits a convenient grip of the flap l.

The leaf 3 and the flap 4 may be cut from sufficiently stiff sheets of paper, cardboard, Cellophane, plastics or any other suitablematerial, the

flap being. preferably made of transparent material, for example, of transparent Celluloid or Cellophane.

The book marker is permanently affixed to the book by connecting the part 5 of the leaf 3 to the page 2, for example by pasting the gummed side of the part 5 to this page, preferably in a position where the left edge H] of the leaf 3 is near and parallel to the inner side of the page 2 and where a part of the flap 4, preferably about half of it, projects over the upper edge of the book as shown in Figs. 1 and 2.

When the reading begins, the reader lifts the flap 4 and releases the same over the first reading page where the flap will rest until turning of this page makes the flap slip over the upper edge of this page and spring to the third reading page on the next leaf of the book. This slipping and springing is correspondingly repeated whenever a page is turned whereby the flap 4 always automatically comes to rest on one of those two pages which are just open and read, for example on page H in Fig. 3, and connected parts of the base leaf and of the flap form a bridge bridging over all pages positioned between the pages ll and 2 as shown in Fig. 3. Any print on the page II that might be covered by the flap 4 is nevertheless readable due to the transparency of the flap. Also any advertisement that might be printed on the front of that part of the leaf 3 r 3 that projects over the edge of the page H is visible throughout the reading of the book.

When the book is closed, the flap 3- retains its position over the page H, marks this page and enables the reader to re-open the book at the reached passage.

For storage or shipping, the leaf 3 together with the flap 4 is turned or folded down around the crease B in the direction of the arrow :2 in Fig. 2 into the position shown in Fig.4. In this position, the book marker is completely concealed when the book is closed.

I desire it understood that my invention is not? confined to the particular embodiment shown and described, the same being merely illustrative,'

and that the invention may be carried out in other ways without departing from the. spirit of my invention as it is obvious that the embodiment shown and described is only one of the many that may be employed to attain the objects of my invention. 7 7

Having described the nature of my invention and how it operates, what I claim and desire to secure by Letters Patent is:

1. A book marker comprising a leaf having a folding line and two parts turnable relatively to each other around said folding line, and a resil iently bendable flap having a part permanently and closely aifixed to a part of the surface of said leaf and having another part extending in the direction to said folding line and forming a continuously resilient continuation of said affixed part without any foldably weakening lines whereby said flap, in unbent condition, is positioned parallel to said leaf and, in bent condition, tends to return into said parallel position, said folding line being located beyond the free end of sai flap.

2. A book marker comprising a leaf having a folding line and two parts turnable relatively toeach other around said folding line, an adhesive layer on one of said parts, and a resiliently bendable fiap having a partppermanently and closely affixed to a part of the surface of the other of said leaf parts and having another part extending in the direction to said folding line and forming a continuously resilient continuation of said affixed part without any foldably weakening lines whereby said flap, in unbent condition, is positioned parallel to said other leaf part and, in bent condition, tends to return into said parallel position, said folding line being located beyond the free end of said flap.

3. A book marker comprising a leaf having a folding line and two parts turnable relatively to each other around said folding line, one of said parts having an adhesive surface adapted to be affixed to a page of a book in a position where the other part, in unfolded condition of said leaf, projects beyond an edge of said page, and aresiliently bendable flap having a part permanently and closely afidxed to a part of the surface of said projecting, leaf part and having another part extending in the direction to said folding line and forming a continuously resilient continuation of said afiixed part without any foldably weakening lines whereby said flap, in unbent condition, is positioned parallel to said projecting leaf part and, in bent condition, tends to return into said parallel position, said folding line being located beyond the free end of said flap.
