Application filed November 6, 1915. Serial No. 59,955.

To all whom it may concern.

Be it known that I, CARROLL M. AUMENT, a citizen of the United States, and resident of Strasburg, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Book-Cover Protector, of which the following is a full and clear specification.

My invention particularly relates to a book-cover protector for any book or pamphlet, but is particularly useful in protecting books used in schools, colleges, etc.

In the majority of the public schools of the country, books for the students are supplied by the school board, and to increase the life of the books as well as provide for sanitary requirements, it is the practice to cover all school books with a aper protector or outer cover. This work of covering the books is frequently done by the students, either at school or at home, with the result that a good deal of the students time isconsumed and the resulting covered books are far from uniform. The covering of the books is particularly necessar because they are transferred to diiferent students a number of times, depending upon the life of the books.

The purpose of the present invention is to provide a bound book with a cover pro tector that will avoid the necessity of using a home-made cover protector and which will lend uniformity to the appearance of the school books and increase the length of service.

In its simplest form, the improved book cover protector comprises a protector sheet permanently attached at one or more points to the book cover and provided with means for facilitating its removal when it becomes worn or soiled.

In its more ractical and useful form, the invention includes such a book cover protector formed of a. plurality of superimposed sheets of proper material permanently attached to the cover at one or more points and completely inclosing the cover. The means for facilitating the removal of the protector from the book cover comprise weakened lines or portions of the protecting material by which the material can be neatly torn away and removed from the book cover. Any suitable device may be employed for this purpose including scored lines or perforations and wherever such expressions as scored line, perforations, separating lines and the like are employed in the claims, such term is intended to indicate any device of this character which is intended to confine the tearing action to a predetermined line extending between a major portion which is to be removed from the book and a minor portion from which said major portion is removed. In the form embodying a plurality of cover protector sheets. it is preferred to have the weakened lines or zones of the sheets out of register with each other, so as to avoid the danger of removing more than one protector sheet at a time. It has been found desirable to also provide each of the pluralitv of protector sheets with a pcrfm'ation into which a sharp ii'istruinent can be inserted for starting the tearing of the protector sheet from the cover, and in case of using these starting openings it is preferred that the openings of the several sheets be placed out of register with each other.

By reason of having the same style cover on the books of all students, the color, size and general appearance will be more pleasing due to this uniformity. v

The above and other obiectsand advan tages of my improvement will fully appear from the followingdescription taken in connection with the accompanying drawings and be explicitly defined in the appended claim. I wish it understood, however, that this dis closure is illustrative only and that the principle of my invention can be embodied in constructions other than the one specified herein.v

On the drawings in which similar parts are referred. to by the same reference characters,

Figure 1 shows the book-cover protector applied to a book.

Fin. 2 is a highlv magnified view, showing the several covers and how they may be quickly removed.

Fig. 3 is a perspective view showing the several superimposed covers.

In the drawings, an ordinary bound book with stiff covers hinged to the back is shown in the usual way. In binding such books the common practice is to provide such book of leaves with strengthened cover-attaching sheets for fly leaves which are glued to the previously prepared cover for securing the book in the Cover.

In preparing a bound book with the improved cover protector, I propose to mount one or a number of protector sheets upon the previously prepared book cover in such manner that the fly leaf of the book will be glued to the inside of the book cover after the protector is in place. In accomplishing this the protector is permanently secured upon the book at one or more points without interfering with the removability of the main body of the protector when it becomes worn or soiled.

In producing the cover protector, suitably blanked out sheets of proper material are prepared with weakened lines formed by scoring or perforating, these weakened lines being located with. proper regard to their desired position with reference to the book cover when the protector is folded and se cured thereon.

The drawing shows a cover protector made up of three superimposed sheets or layers. After the book is ready for covering, I take the inner paper cover protector and secure it to the inner cover of the book itself along a line or at certain points. This may be done by gluing or other securing means. This gluing or other securing means goes as far as a certain line and then the rest of the cover protector is free to be torn off by the insertion of a knife, finger-nail or other suitable means. After the inner cover protector has been secured to the binding of the book, the next one is secured or superimposed over that cover protector. The line of gluing and the tearing or apertured space is not directly placed over the tearing line of the first cover protector, but is purposely made some slight distance away so that two covers will not be accidentally torn simultaneously. This is clearly shown in Fig. 2.

At 10 is shown a book with 11 shown as the back of the book. 12 is a fly wheel pasted to the book in the usual way. The numerals 1 1, 15 and 16 indicate book-cover protectors. Book-cover protector 14; has a slot 7. 15 has a slot 6, and 16 has a slot 5. Each cover protector 14-, 15 and 16 has an apertured or weakened line 19, 18 and 17 respectively. Cover 14 or the inner cover protector is not pasted to the back of the book 11 at 21 and 22, only at 20, thus I have only a thin edge of pasting around the inside of the back of the book 11. It is apparent that when the outside cover 16 is removed by inserting an implement in slot 5, that the cover will be removed along apertured line 17. Should an implement be inserted in apertured line 17 to facilitate the removal along weakened line 17, it could not possibly injure or mar the next cover protector 15. Similarly the removal of the second cover protector could not injure the lower protector 14:.

After the outer cover protector has become soiled or worn, it can be removed by inserting a pointed instrlunent'in the tearing hole or perforation 5 and tearing or cutting the protector sheet from the book. The weakened or perforated lines 17, 18 and 19 serve to define the tearing edges of each cover protector so as to insure a neat result to the removing operation. This is clearly shown in Fig. 2. When the outer protector is removed, the book will have the next inner protector sheet presented to form an en: tirely new, sanitary and clean cover proteeter.

While I have shown an improved book cover protector consisting of only three superimposed sheets, it will be clear that any practical number of such protector sheets can be employed, the number desired depending largely upon the length of life of book from other standpoints.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and mode of operation will be readily understood by those skilled in the art to which the invention-appertains. While I have described the principle of operation together with the form which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that sueh'changes may be made when desired as fall within the scope of the appended claim.

Having described my invention what I believe to be new and desire to protect by Letters Patent, is:

The combination with a bound book, of a plurality of superimposed cover protectors each provided with a portion secured between the inside of the cover and a fly leaf secured thereto, said fly leaf covering and holding the extreme outer edge of each of said protectors, said cover protectors being provided with means adapting other portions covering the outer surface of the book cover to be readily detached, each of said cover protectors being provided with an elongated slit running at and along the lower edge thereof, said slits being out of register with each other.
