'SPESIFIOATION forming part of Letters Patent N o. 694,841, dated March 4, 1902. Application funi March 25, 1901. Serin No. sas-ie.v (no man.)

To @ZZ whom, it may concern:

Be it known that I, FRANKLIN R. DEERICK, a citizen of the United States, residing at Brodhead, in the county of Green and State of Wisconsin, have invented a new and useful Snpplemental-Book-Cover Fastenenof which the following is a specification.

This invention relates to book-covers, and more especially to supplemental covers used in protecting the permanent covers of books.

In placing books upon the market publishers as a rule protect the permanent covers thereof by means of a temporary cover that may be readily'removed for the purpose of examining the design of the permanent cover, binding, dac; These temporary covers are made of a single sheet of paper of a width equal to the length of the book and long enough to extend about the outer surface of the permanent cover and have their ends turned inwardly over the side edges ofthe same. The title of the book is usually printed upon the rear side of the same. Ordinarily purchasers of books having these temporary covers retain the same, and while they are excellent for the purpose a great objection to them is that they are continually slipping out of place, much to the annoyance of the reader. Now after a book has been purchased the necessity or desirability-of examining the cover and binding has ceased, so that the temporary cover may be made into a supplemental one that is not displaceable.

The object, therefore, of the present invention is to improve these temporary covers by providing meanswhereby they may be madev into non-displaceable supplemental covers that will not slip out of place and will thoroughly preventthe permanent covers being soiled or otherwise injured.

A further object is to provide means in theV form of attachments that may be applied to the usual temporary covers for holding them securely in place.

In the following specification is described the preferred embodiment of the invention, and said embodiment is also illustrated in the accompanying drawings, wherein- Figurel is a perspective view of a book having the improved supplemental cover applied thereto and showing the inner face of the permanent cover. Fig. 2 is a perspective View of the exterior ot' the book. Fig; 3 is a longitudinal sectional view contiguous to the outer edge of one cover. Fig. 4 is a crosssection taken on the line X X of Fig. 3, and Fig. 5 is a plan view of' the attachment.

Similar numerals of reference designate corresponding parts in all the figures of the drawings.

An ordinary book has been shown in the drawings, the body being designated A and the two permanent covers B. Over these permanent covers is placed the supplemental cover C, which is made of a sheet of material,

preferably, though n ot necessarily paper, said one face is provided with a gummed or adhesive substance F, which must necessarily extend along the two edges forming the legs ofthe triangle. -In use the tabs are bent or Y folded over the top and bottom edges of the permanent covers and are secured to the inturned portions and the upper and lower edges 'of the outer faces of the supplemental cover by means of the adhesive substance F. They thus prevent the displacement of the supplemental cover.

The present construction presents several important features. In the first place an ordinary removable temporary cover maybe permanently secured in place to protect the permanent covers of a book. Furthermore, because of the construction of the tabs the ends of the temporary cover need only be folded in a distance suiicient to attach the edges ofthe said tabs. At the same time the width of the paper is sufficient to cover the outer surface of the book. A great saving in paper is thus eected.

From the foregoing it is thought that the construction ,operation,and many advantages of the herein-described invention will be ap- IOO parent to those skilled in the art Without further description, and it will be understood that Various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacricing any of the ad van tages of the invention.

HavingV thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A supplemental covering for books, comprising a sheet of material having a Width substantially equal to the length of the book to be covered, and of a length sufficient to extend about the outer faces of the permamy own I have hereto affixed my signature in 25 the presence of two Witnesses.
