HE RTE L E MD) fiK/M A T TORNE Y United States Patent Ufice 3,083,988 Patented Apr. 2, 1963 3,083,988 PERPETUAL ENGAGEMENT BOOK Antler de Hertelendy, 103 Waverly Place, New York 11, N.Y. Filed Dec. 7, 1956, Ser. No. 627,033 2 Claims. (Cl. 281-19) This invention relates to a perpetual engagement book.

It is the principal object of the present invention to provide a perpetual engagement book in which the pages are formed with a smooth surface that can be cleaned after use and in which the pages have indicated thereon the days of the month and can be turned in order through three hundred and sixty degrees to bring up a new date and to align the pages turned over for use during a subsequent month or other period of time.

It is another object of the invention to provide a perpetual engagement book in which the engagements for the current day will lie on the front page and thereby obviating the time consumed in searching and at the same time provide an engagement book that will have room for engagements over a considerable length of time.

It is a further object to provide a perpetual engagement book in which the pages or leaves are separately hinged upon a hinge pin which serves as a turning pivot by means of tongues or hinge projections and wherein these tongues are so dimensioned and positioned that they can be easily separated by touch from one another so as to be able to select any desired page and wherein these tongues will bear the date mark so that the pages can be immediately turned to any particular date in the book.

It is still a further object of the invention to provide an engagement book constructed of pages which can be turned through three hundred and sixty degrees with a cover or stand to which the hinge pin on which the leaves have been assembled can be releasably attached and easily removable therefrom when turning the leaves back.

Another object of the invention is to provide an engagement book which does away with the necessity heretofore experienced in such books to have to either transcribe engagements into a new book when the old one is up or to carry two books when it is about to be up.

Still further objects of the invention are to provide a perpetual engagement book, having the above objects in mind, which is of simple construction, inexpensive to manufacture, a simple hinge construction with pages which can be easily cleaned with soap and water, cleaning fluids, or simply with saliva, durable, compact and assuming only the thickness of the superimposed leaves, bendable hinge connections, light in weight, effective and efficient in use.

For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, which illustrates an engagement book made for the period of one month and, in which FIGURE 1 is a fragmentary plan view illustrating the manner in which the hinge pin is assembled in the cover cli s,

16. 2 is a fragmentary plan view showing the bendable hinge projections and the hinge pin,

FIG. 3 is a plan view of one of the leaves separated from the hinge pin,

FIG. 4 is a perspective rear View looking upon one end of the assembly and illustrating the motion of the leaves as they are turned from the front through three hundred and sixty degrees to the back thereof,

FIG. 5 is an enlarged transverse sectional view showing the leaves and illustrating the manner in which the hinge projections are bent to allow the leaves to lie fiat and superimposed and flush upon one another, the section being taken generally on 5-5 of FIG. 2,

FIG. 6 is an illustrative and perspective view showing the manner in which the separate leaves are cleaned for further use, and '7 FIG. 7 is a sectional view taken on line 7-7 of FIG. 1.

Referring now to the figures, 10 represents a leaf formed of paper or plastic material with a surface on which a pencil mark can be made and thereafter readily cleaned from the surface by soap and water, cleaning fluids or simply saliva. Each of these leaves are divided into three spaces 11 on which the engagements may be written and smaller spaces 12 used for indicating the appointed time. Each of these leaves have two

bendable hinge projections

13 and 14 separated from one another and adapted for connecting the leaf to hinge pin '15. These hinge projections of the different leaves lie adjacent one another on the hinge pin 15, so that any one of the hinge projections for any given leaf can be readily selected from the other projections and the leaves readily turned so that the selected leaf can be made to appear quickly. The hinge projections are narrow and with the leaves being made of paper or plastic material the projections can readily be formed about the hinge pin by folding, and gluing or heat sealing. The

projections

13 and 14 are bendable as best illustrated in FIG. 5 so as to permit the main body of sheets to lie flush and superimposed upon one another and the thickness thereof to be added up to be only slightly greater than the hinge pin and hinge projections. If the hinge connections were not bendable the flush engagement of the sheets with one another would be impossible.

The projections 13 are marked with dates of the month and each leaf will have three date areas. The leaves are arranged chronologically and are separately hinged from top to bottom so that they can be turned up in sequence.

A special page can be added to the assembly for marking further engagements beyond a months time. All of the past engagements are supposed to be crossed out or Washed off to leave the pages clean for writing down future engagements.

If the owner wants to put down an engagement for some future date or look up engagements already made for that date he opens the book to the desired page by holding down its tongue and lifting the pages thereover. The tongues or projections have identifying date numbers visible at all times which as explained helps the owner to quickly find and expose the desired page.

A page of the past, normally the top page, if turned back on the hinge pin becomes the bottom leaf. In that position it will be available for inscribing engagements for the following month. Turning over the pages with the past engagements brings a top position for the present day engagements.

If the book is to be carried in the owners pocket a suitable foldable cover 16 may be used for this purpose. Two clips '17 and 18- may be riveted by rivets 19 to one side of the cover. The ends of the hinge pin can be slid into position as shown in FIG. 1 under the clips 17 and 18. The assembled pages are disconnected from the clips when any one of the pages are to be turned back. The cover 16 will prevent the pocket from being soiled and the written matter on the top page from being removed or rubbed off.

Eleven leaves or pages have been shown assembled upon the hinge pin 15, with one page serving for three consecutive days and the left over or eleventh page serving for a thirty-first day and for reserve space on which other matters may be listed. The number of pages of the book can be varied. They can be reduced if both sides of the same leaf are to be reserved for inscriptions. The book can be made for the period of one whole year 3 also; in that case the pages will bear the names of the month.

It should now be apparent that there has been provided a compact and efiicient engagement book by which the book can have continued use in that the pages can be turned over one another through three hundred and sixty degrees and still allowed to lie flush upon one another to consume little space and in which the pages can be easily cleaned and adapted for perpetual use.

While various changes may be made in the detail construction, it should be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What is claimed is:

1. A perpetual engagement book or the like comprising leaves superimposed and in flush face to face engagement with one another to provide a relatively thin book, each of said leaves having longitudinally-spaced resiliently bendable hinge projections extending from one edge, said hinge projections of one leaf lying adjacent to and longitudinally olfset to the hinge projections of the next leaf, said hinge projections having hinge openings at their free ends thereof, a hinge pin running through the openings of all of the hinge projections of the leaves to place the openings in single line, said leaves being turnable singly or together through three hundred. and sixty degrees about the hinge pin, said hinge projections being bent under bending stress while the leaves of the book are closed.

2. A perpetual engagement book or the like as defined in claim 1, and a book cover and laterally-spaced spring clip retainers secured to the inner side of the cover for releasably receiving the hinge pin whereby the pages may be released from the cover to turn the pages.
