10 Claims. '1

This invention relates to devices for marking positions in a book to facilitate the readersquick return to the desired reading position in the book. More particularly the invention deals with a device of the character described which has means for clamping the same to a part of the cover or binding of the book, with means pivotally and slidably supported in connection therewith for engaging the upper surface of an exposed ,page of a book and to automatically drop onto successive pages in the operation of turning thesame. Still more particularly, the invention deals with a book-mark device of the class described wherein the pivoted and sliding member of the device includes a supplemental pivoted part adapting the device for use in books of relativel wide range in thickness. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing in which certainembodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the Views, and in which:

Fig. 1 is a sectional view throughan edge portion of a book, illustrating the arrangement of one of my improved book-mark devices thereon and indicating the method (if-turning pages in the use of said device.

Fig, 2 is a plan View of the'structure seen in Fig. 1, with part of the construction broken away.

Fig. 3 is a face view of the device as seen in L Figs. 1 and 2.

Fig. 4 is a View similar toFig. 2 showingta modi- .fied form of device.

Fig. 5 is a face View of the device as seen in Fig. 4; and

Fig. 6 is a perspective view of partof the device shown in Figs. 4 and 5.

-In illustrating one adaptation and use of my invention, I have indicated in Figs. 1 to3 inclusive, at IU, part of a book covenand'at H a number of the pages of the book, I l indicating a top page in the process ofbeing turned beneath the marker finger or element I2 of the marker device. This finger constitutespart of a substantially U-shaped frame I3, the finger I2 comprising a short arm which parallels a longer arm I4, the latter joining the arm or finger 1.2

in a cross head l5, having a loop shaped fingerpiece portion it. The long arm M has at its free end an enlarged head IT.

The marker device also includes a mounting member 18 in the form of a strip of sheet material bent and fashioned to form a spring clip l9 and a wall portion 20 paralleling the wall .21 of the clip l9 and having at'itsfree end an in- Wardly extending flange 22. The flange 22, as well as the folded end 23, i apertured-to receive the rod i l, the

portions

22 and 23 formingbearing guides in the sliding movement of the rod 14 in movement of the device into the innermost operative position shown in-the drawing-andin moving the finger or arm 12 outwardly beyond thelimits of the page H.

The mounting member 18 is preferably arranged adjacent one edge portion of the book, preferably the lower edge, so that the finger-or arm 12 rests, by gravity, toward the upper .or rear edges of the pages 11 and .in turning the pages, they-arepreferably slid frombeneath the finger l2 in the-manner indicated in l l' and as one page is removed, orturned, the finger I2 automatically drops, bygravity, onto the next adj acentpage.

Thefinger piece It is-used tograsp thedevice in returning'the 'readento the proper page and in assisting in opening the book at the proper page. -It will benoted from aconsideration of Figs. land 2 of the'drawing that the entire device, or for the most .part, is retained .within boundaries of the book covers, excepting'that. the fingerpiece E16 protrudes :slightlyfor free. engagement by-thefingers of ahan'd thusthe device maintains a neat and finished appearance upon the book in' connection with which it is supported.

-In Figs. lto 6 inclusive, I haveshown aslight modification in which figures, 18 represents a supporting member, identical with the member shown in Figs. 1 to 3'inclusive, and instead of using a one-piecexwire frame I53, as in Figs. 1,.to. 3, the swinging and-slidingunit of the devicev comprises a rod -|-4',-genera1ly similar to therod Hi to theouter end ofwhich is secured or riveted, along lever or arm 2t, preferably of'strip material; as indicated.

'Pivotedtothe-free. end portion of the levergzli,

as at 25, is-a'shorter leverjlmthe-free end-portion of which carries -amarker finger or element I 2, generallysimilartothe. finger. or elementali. The free end portion of the lever. 26: also has an offset flange 21 which is adapted to strike upon the'upper edge of the lever 24.110 limitdownward movement ofthe lever-26, 'whileat the same time, permitting said 16181115. to collapse so that the'fingepm' may extend to thelast page. or

pages ofthe book.

The outer or freeend portion .of the:;lever.;24

has an ofisetand angularl garrangedstop plate 28 which checks swinging movement of; the lever 26 in the other direction, In other words, when a very thick book is being read, the two levers 24 and 26 may extend to a relatively open position, but at all times within an angle less than one hundred and eighty degrees. This enables the pin or finger [2' to be moved a much greater height than the finger l2, which swings on a definite radius with respect to the axis [4.

The device of Figs. 4 to 6 inclusive operates substantially in the same manner as shown in Figs. 1 to 3 inclusive, except that the finger l2 moves downwardly to a position closer to the rod gagement with book pages, means joining the finger with said rod to allow the finger to automatically move onto successive pages in maintaining a constant marker for the pages of a book, and said last named means comprising a part fixed to and swinging with the rod in the rotation thereof in said bearings.

5. A book-mark of the class described comprising a clip adapted for engagement with an outer wall portion of a book, said clip having spaced wall portions apertured to form bearings, an elon- I gated rod rotatably and slidably mounted in said M, as the finger l2 reaches the bottom or lower.

page of the book.

It will be apparent that my improved device may be used as a marker for various types and kinds of supports other than books, wherever it is desirable to designate a position between a number of sheets or pages. In all instances, the clip or supporting member will be made to suit the particular mounting intended.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
