COVERING FOR BOOKS.
SPECIFICATION forming part of Letters Patent No. 639,451, dated December 19, 1899. Application filed June 6,1898. Serial No. 682,682. (No model.)
To crZZ whom it may concern.-
Be it known that I, WILLIAM H. SMALLEY, a citizen of the United States of America, residing at Yonkers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Coverings for Books, of which the following is a specification.
My invention relates to temporary coverings for books, such as are used for protecting the covers of the books while they are in use and which are usually made of paper, cloth, or other flexible material.
The object of my invention is to furnish such a temporary book-covering that can be quickly and readily applied to a book and that will also have the greatest thickness on its back and sides to insure the longest wear and consequent protection at such parts.
My invention consists principally of a sheet of flexible material folded on two parallel lines and said folded material being transversely folded 011 two parallel lines and said latter folds being secured to the first-folded portion, whereby the two covers of the permanent book-cover may be quickly inserted between the outer thickness of the sheet and the first folds and the outside of said permanent cover being covered by every fold and thickness of the covering except one.
The nature of my invention will best be understood when described in connection with the accompanying drawings, in which- Figure 1 illustrates in plan a sheet of paper or other flexible material creased in lines indicating where said sheet should be folded to make a temporary covering. Fig. 2 illustrates the sheet after the first operation of folding. Fig. 3 is a plan of the completed covering spread out and looking at its inside. Fig. 4: is an enlarged section through the line 4 4: of Fig. 3, but also showing the removable covering applied to the permanent cover of a book. Fig. 5 is a transverse section taken in the line 5 5 of Fig. at. Fig. 6 shows a book with its cover spread out and with the removable covering applied thereto.
Similar letters of reference designate corresponding parts throughout the several views of the drawings.
Referring to the drawings, the letter A designates the blank of paper or other flexible material from which the removable bookcover is to be constructed. The sheet A is first folded along the parallel lines or and b, with the folds c and d over the main part 6, as shown in Fig. 2. The folded sheet A is again folded in the parallel linesf and g, and the under flaps h and iof the last fold are secured by gumrning, stitching, or otherwise to the folds c and d. The removable covering is now complete. In order to apply said covering to a book, the'two covers 13 and 0, form ing the permanent cover. are inserted, respec* tively, between the inner fold It and the folds 7L and t on the two sides of the covering A, (see Figs. 4, 5, and 6,) and when the covers B and Care shut the covering A will bend at Z at the back of the book.
From the above it will be seen that the removable covering A can be quickly and readily put on or taken off the book and that the outside of the covers and the back of the book,
when there is great wear, will be protected by several thicknesses of the material forming the covering A and that said covering will therefore last much longer than it other= wise would.
What I claim as new is 1. A covering for books cousisti ng of a sheet of flexible material of substantially rectangular form having two longitudinal folds overlapping each other at their inner ends to form a longitudinal belt of triple thickness throughout the entire length of the back of the covering and having also transverse folds at right angles to the longitudinal folds and embracing a portion of said longitudinal folds, and said transversely folded portions forming pockets for the reception of the book-covers, substantially as described.
