WILLIAM BEV. HARISON, OF NEW YORK, N. Y.

BLANK FOR BOOK-COVER PROTECTORS.

SPECIFICATION forming part of Letters Patent No. 473,502, dated April 26, 1892..

Application filed June 25, 1891. Serial No. 397,556. (Model) To all whom it may concern.-

Be it known that I, WILLIAM BEVERLY HARISON, a citizen of the United States, re siding in the city of New York, in the county and State of New York, have invented a new and useful form of blank or an Improvement in Blanks for Book-Cover Protectors, of which the following is a specification.

My invention has for its object the preparation of Manila or other strong paper, parchment, or book-cover material, so that it may be easily adapted to and made'into a cover or protector for either of a number of differentsized books without cutting the blank.

The exact nature of my invention is set forth in the accompanying drawings, which may be easily understood from the following description.

Similar letters refer to similar parts in each of the several views.

Figure 1 is an inside View of the blank, the ends being turned over at A A to strengthen these edges. Adhesive material is applied at B B. Fig. 2 represents the same with the two sides folded down at the dotted lines 0 C, Fig. 1. In this View the corners D D, where adhesive material is applied, are exposed. Fig. 3 shows the manner of measuring the length of the ends E E to be folded down at F F. Fig. 4 is a completed cover, the sides and ends having been folded down, making the pockets G G for the covers of the book.

To make a cover or protector of this blank the two sides are folded down, as in Fig. 2, so that the width of the blank when folded is a trifle more than the length of the book to be covered from top to bottom. The gum, as shown at B B, is then moistened and the fold fastened down. The book is then laid in the cover, as in Fig. 3, and the two ends E E slightly creased over the edges of the books cover at F F to indicate its size. The book is then removed and the ends E E folded down where creased at F F and fastened down by moistening the gum at D D. The cover then presents the appearance shown in Fig. 4, G G being pockets formed by the foldedover ends E E. The book to be covered can now be easily placed in the cover by bending its covers back slightly and thrusting them into the two pockets G G.

To strengthen or stiffen the cover or protector the ends or sides can be made of double material, or the whole cover reinforced with cloth or other material. Guide-lines can also be printed from side to side or end to end, or both, to assist in folding evenly the sides and ends.

I am aware of the patent granted George Cornwall, dated July 8, 1890, No. 431,876, and lay no claim to anything claimed by said patentee. It will be seen, however, that said patentee makes no claim to the cover when gummed and not stitched, the gummed cover having been made for upward of ten years by1 myself and others, though not offered for sa c.

Having described my invention, I claim and desire to secure by Letters Patent 1. A blank for book-cover protectors, consisting of a rectangular piece of paper, strengthened or reinforced throughout or in part by cloth or similar material attached thereto, and turned-over edges provided at the ends of the said piece of paper, which is gum med on one side at the top and bottom edges and on the opposite side at the corners on y.

2. A blank for book-cover protectors, consisting of a sheet of paper, which is provided with gummed surfaces at any two opposite edges on one side of the paper and with gummed surfaces at the corners of the paper on the opposite side of the sheet.

3. A blank for book-cover protectors, consisting of a sheet of paper of substantially rectangular form, provided with gum upon one side near two opposite edges, with gum at the corners on the opposite side of the paper sheet, and with rulings parallel to one another on that side of the paper on which is the first-named gum.
