To (DZ/Z 7071/0717 it may concern:

Be it known that I, OnDRIo (humans, a subject of His Majesty the King of Great Britain, residing at Bath, in the county of Somerset, England, have invented a certain new and useful Improvement in Bookbinding, of which the following is a specification.

The invention relates to an improvement in bookbinding, the object being to insure a greater flexibility between the body of the book and the cover.

According to the invention means are provided whereby the cover has a slightly-yielding attachment to the rest of the book, so that the durability of the book is increased, and, further, stouter leather or binding boards for the cover may be employed in cases Where it is considered desirable witho ut the usually increased risk of strain or of the cover breaking away from the book. 1V ith this object the end papers or first few leaves or section of the book are covered along their back edge with some cotton material, linen, or jaconet, the outer edge of which is employed for assisting in attaching the book to the boards; but the other edge or that on the inside of the section has a plait or fold formed therein, so that the fabric will take substantially the appearance of the letter M in section. In the second inside opening formed by this fold (the first being occupied by the end papers) the second section is inserted and secured, as usual, by pasting and by stitching in such a way that the single plait left outside or at the back of the two sections is not prevented from opening. Obviously the last two sections of the book or the last section and end papers will be treated in the same way, with the result that the covers and their attached papers or section will be provided between them and the next section with a yielding cotton or linen connection, which will slightly open when the covers are bent back, and thus prevent the strain usually created at these points.

In the accompanying drawings is shown a manner of carrying the invention into effect.

In the drawings, Figure 1 is a perspective view of an opened book. Fig. 2 is an end View of a part of same, on an enlarged scale, the parts being separated and the back and covering to the side boards omitted. Fig. 3 is a back view of a portion of a book on a scale also larger than Fig. 1, but without a back or side board.

The first section 1 of the book consists of the binders end papers as distinguished from the pages sent him by the printer, which consist of the book itself from title-page to colophon. This first section may vary in its composition, but in the drawings it is shown as consisting of a sheet, usually of decorated paper, folded to form leaves 2 and 3, and a sheet folded to form leavesi and 5. The fold of leaves 2 3 is preferably reinforced at the back by a folded strip of cotton, linen, jaconet, or like fabric 6 pasted thereon, and the leaves 3 4 are pasted together. The section 1 so formed is inserted in the inside of a fold of a piece of cotton, linen, jaconet, or like fabric 7 and, if desired, secured therein by paste. This strip 7 is doubly folded into M form, so that a plait 8 is formed in the center with an outer edge 9 and an inner edge 10. In the inside of the fold between the inner edge 10 and the plait 8 the second section 11 (usually the title-page and first portion of the book) is inserted and pasted, if desired, so that the edge 10 comes between the second section 11 and third section 12, while the edge 9 may be either inserted and secured in a split in the side board 13 or pasted on the inside of same. The leaf 2 is pasted to the side board. It'will thus be seen that the first and second sections are separated by a plait or fold 8 at the back, which forms an expanding hinge. A portion of the first section is pasted to the cover, as described, and therefore moves with the movement of the cover. This construction enables the cover to open more freely than usual, so that the strain between the first and second sections is lessened and there is less chance of the cover breaking away. Any usual or suitable means for completing the binding may be employed with this kind of plait-backing for the first and second sections.

As shown in Fig. 3, the stitching 13 passes through each section out and in again and incloses tapes 14:, which are secured to the side boards in the usual Way, while the kettle-stitch 16, attaching the sections together as usual, is also employed. With this latter stitch it will be seen that the first and second sections are secured together by such stitch near the top and bottom, so that the plait 8 is closed; but as this is the first stitch of the kettle its rigidity and holding power is not so great as it is further on, so that it can yield slightly, or the kettle-stitch can commence at the second section, as shown, the first and second sections being connected by a single stitch 17 which pulls or yields even more freely. In

practice, however, the kettle-stitch always al- IIO lows a slight opening of the plait to take place when the cover is opened or bent back.

Obviously the last two sections of the book or last section and end leaves are backed and treated in the same way as that described for; those in the front of the book.

WV hat I claim is 1. The combination of signatures secured together in the usual manner, with a cover therefor composed of a back and side boards, and a hinge of flexible folded material between each of the outer sides and the corresponding side board, said hinge being composed of material folded into an WE shape, the outer leaves of said hinges being secured to said covers and to the corresponding outer signatures respectively, substantially as described.

2. The combination of signatures secured together in the usual manner, with a cover therefor composed of a back and side boards 20 and a hinge of flexible folded material between each of the outer sides and the corresponding side board, said hinge being made of flexible Jnaterial folded into an M1 shape, one of the CEDRIO OHIVERS.
