1%. COHEN BOOK INDICATOR Filed April 4, 1938 N E H, C ,A C C E B E R.



Patented Nov. 15, 1 938 UNITED STAT-Es PATENT mm V 1 Claim. This invention relates to book indicators whereby a reader will. have a positive indication of thepage numberand the line of the page where the reader has left off while reading the book. i

An object of this invention is to provide a book indicator having an elongated strip with a fold at one end designed to engage the upper end of a page and having a slot lengthwise thereof for engaging and guiding a numbered indicator up or down the page to the particular line last left of! in reading the book.

Another object of this invention is to provide in combination with an elongated and slotted strip having means at one end for securing to the top edge of a page, a numbered indicator having a slotted pointer on top thereof, through which slot thereader mayseeat a glance th page number last left ofi.

Another object "of this invention is to provide a numbered indicator which will provide the reader with the information of the month,

date and page and also the lastline left off for the reader to resume reading. 7

With the above and other objects in view, the

35' ing the application of my book indicator thereto.

Figure 2 is a front elevation of the assembled book indicator showing a set month, day' and page number. n

Figure 3 is a side elevation of the construction 40 shown in Figure 2-. V a

Figure 4 is a fragmentary view of a modified carrier.

In the illustrated embodiment of the invention, the numeral Ill indicates my book indicator 45 comprising an elongated carrier member ll of strip form and having a ,slot l2 oentrallythereof and substantially throughout its entire length. As best shown in Figure 3, one end ofthe carriermember II has been folded at one end. The 50 fold II is designed to form a clip for embracing the opposite faces of the upper portion of the pages 14 of a book I! so that the slot l2 may form a guide trackextending downward from the upper end of the book.

ll Rotatably mounted on a'pivot ii are a plurality of circular disks 11, 11!, i9, 2t. ,m pivot d6 extends into engagement with the slot i2- and so that the said disks are in slidable relation with said carrier member? H. Pivotally mounted on top of the upper disk 20 is a pointer 2|. It is to be noted that all the'disks and the pointer form. a slidable unit relative to said carrier.

The pointer 2| has a slot 22 lengthwise thereof. The slot'22 is of sufficient lehgth to permit vision therethrough of the end portions of all the /disks.

As best shown in Figure 2, the disks ll to 20, inclusive, have indicia thereon all around their outer circumferences.- .A line of indicia comprising all said disks may thusbe viewed through the slot 22.

For the purposes of the present invention which is to provide means for indicating at. a glance the page last left off by the reader, I prefer to as print numbers from 0 to 50 on thedisks iiand 19. On the disk I9 I prefer to print numbers from 1, to 31. On thetop disk I prefer "to print indicia indicating the months of the year. For this purpose I may also print on the pointer 2| indicia indicating the month; day, and page.

I may also print oh the pointer indicia indi-' eating a particular year inasmuch as this book indicator may= beused as a greeting device so that the sender may set the two top disks with go indicia indicating the year, the month and the day, that is the birthday of the particular person to whom it may be sent as a greeting device. From the above it will be noted that the reader of a book may attach the device to thefbook with the folded portion of clip it in engagement with the upper portion of the pages as shown, and by manipulating the disks H and I8 may indicate the page number last left ofif.

Also the pointer 2| in the particular setting may be rotated jointly .with the said disks to a point where \the pointer will be in line with the line last left off. The above relates to the use of the device when placed directly side-by-side with the page last left off, wherein it is possible to indicate the last line itself. It is, however, within the provinceof this invention'to mount the device inside the cover and in that case the reader may set the book indicator to indicate thev page number last left off without having recourse to the pointer for indicating the line last left ofl.

Referring to Figure 2, it wil be seen that the disks 20 and I9 having the month and day indicia make it. possible for the reader to also indicate the month and day on which the particular page was last left off forthe reader to resume reading.

It is to be noted that the material of which the carrier II is made will have an element of rigidity or stiffness so that it will be adapted to maintain its form while the upper members are slid thereon. The device may be made of paper, Celluloid, leather or metal having the necessary body.

It is to be noted that the entire device is hidden inside the book when not in use.

This book indicator may have advertising matter printed thereon and serve as a greeting device which may be given away as a gift. The device may also serve as a perpetual reminder so that the month and date indications may serve to remind the reader of appointments made.

Referring to Figure 4 which shows a modified carrier 25 having an unslotted bottom layer 26 so that a pivot may be slidably mounted in the slot 21 of the top layer 28 without contacting the page of the book. The intact layer 26 is attached in any suitable manner to the top layer 28 and thus serves as a shield to guard the pages of the book against damage by the slidable pivot.

I may also modify the clip portion of the carrier by providing a metallic clip 29 secured at one end of the carrier. The clip 29 will serve to positively grip the pages of the book.

It is to be noted that while I have shown my book indicator in Figure 1 with the carrier in contact with the upper margin of the pages of the book, that I may reverse the indicator so that the clip end 01', the carrier will contact the bottom margin oi the pagesor that it may contact the side edge oi. the pages.

I claim:

A book indicator composed of top, intermediate and bottom members, said intermediate member comprising a plurality of concentric disks each having indicia concentrically positioned at the outer circumference thereof, said bottom member forming a carrier for said disks and comprising an elongated strip having means at one end for engaging the opposite faces of a page oi the book and being slotted substantially throughout its length, said top member forming a pointer having a slot lengthwise thereof for viewing indicia on said disks and having a sharp angular outer end, said disks and said top and bottom members being centrally secured by pivot means, said top and intermediate members being jointly slidable as a unit relative to said carrier member due to engagement of said pivot means with said slot in said carrier member, said carrier having an intact and unslotted bottom layer for shielding said book from contact with said pivot.
