CEDRIC GHIVERS, OF BROOKLYN, NEW YORK.

LOOSE-BACK BOOK.

Specification of Letters Patent.

Patented Aug. 1'7, 1909.

Application filed March 15, 1909. Serial No. 483,558.

To all whom it may concern:

Be it known that I, CEDRIC CHIVERS, a subject of the King of Great Britain, residing at Brooklyn, New York, United States of America, have invented certain new and useful Improvements in Loose Back Books; and I do hereby vdeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tof make and use the same.

This invention relates to the loose or throw-off-back method of binding, and the invention has for its obj ect a quick and economical mode of attaching such loose back to the book which will give it increased strength as compared with the modes heretofore employed and will insure straight alineinent of the edge of the back of the book.

In carrying the invention into practice, the end paper of the lining papers or finishing sheets have sewn with them a loose piece or pieces or tab or tabs of jaconet or the like material which are pasted onto the inside of the loose back, or may carry strips of brown or other stout paper or the like which latter are pasted onto the loose back. The loose strips would in the usual course interfere with the tapes to which the signatures are sewn and would prevent them from being pasted to the side boards, but'this is overcome according to the invention by passing the tapes through holes in such loose pieces so that said tapes may be pasted between the lining papers and the boards or be otherwise attached to the boards. y

The invention will now be described with reference to the accompanying drawings, in which Figure 1 is a transverse section of a p0rtion of a book with the signatures, end and lining papers and loose back assembled in accordance with the invention, but without showing any stitching; Fig. 2 shows a portion of same with the parts in a different position and stitched; Fig. 3 is a detail of Fig. 2; Fig. L is a rear elevation of a portion of the book with the loose back partially broken away; and Fig. 5 is a sectional elevation of the loose strip of jaconet combined with the paper strip sepa-rated and shown in the position it has assumed in Fig. l, one of the usual tapes being shown passing through a hole in same.

Like letters of reference indicate like parts in the several views.

a is the book, which may be composed of any number of signatures, are the boards, 0 is the loose back, usually of leather or cloth and having extensions c1, onto which the boards Z9 I) are pasted, and CZ Z are the finishing sheets or lining papers. rlhe front and back of the book are similar and therefore only one need be described. Beside the lining paper Z there is as usual an additional sheet e. Each of the sheets d, c, has four sides d1, cl2, cl3, d4, and el, c?, e3, et, respectively. The liningpaper Z is strengthened at its fold or hinge by a piece of jaconet f, which is pasted onto its sides d1 and d4.

Overlying the strengthening piece of j aconetf, on the sides nearest to the book, is the piece or tab of jaconet g which in this case carries a brown or like paper strip 7i. rThe end paper e is strengthened on its fourth side cl by a strip of aconetc' and the edge or margin of the side c1 thereof nearest to its fold or hinge, is pasted to the adjacent signature of the book, the paste being represented at y'. The sheet e and its strip c' are then sewn to a few signatures of the book in the well known way, as indicated at 7.: in Fig. 3, and also in Fig. 2, after which the side e4 of the sheet is pasted to the adjacent side Z1 of the lining sheet Z with the jaconet strip z', a portion of the strip g and half of the strip shut in between them. l represents another line of stitching, which passes, in this case, through the part (Z3, Zt of the lining paper l at the fold and through the nearest signature or signatures, and which thus takes up the stitching by which said signature is secured to the tapes m, which are near the top and bottom ends of the book and at the middle or other desired points such tapes as usual passing behind the signatures, and being in direct contact therewith by the usual stitching through the signatures. According to the present invention said tapes m are passed through openings p (Fig. 5) in the aconet strips g and the ends of the tapes are pasted to the lining sheets, or rather to the jaconet strips f, between the outermost sides d* of said sheets and the boards Z). The brown paper or like strips 71 or the tabs g where such paper strips are not used, are then folded down over the back of the signatures and pasted to the loose back. Of these strips z., or tabs g, one may be wider than the other, as shown, and may underlap the narrower one. The backs of the signatures may be covered as usual with any reinforcing strips which may be desired. Last of all, the sides (Z4 of the lining papers are pasted to the boards b, b and the side c4L of the end paper c is pasted to the side Z1 of the lining paper CZ.

The invention is net restricted to the precise order of carrying out the above operations, which may be varied more or less as desired.

lt will be observed that the lining carry the loose strip by a line of sewing so that when the strip is pasted firmly to the back it forms an attachment to same which is sewn to the book signatures so that in effect the loose back may be saidA to be sewn tothe book.

l hat l claim is zl. A bound book, comprising a series of signatures connected together in the usual way, lining papers placed in front and back of said series of signatures, and having their folds reinforced' and stitched to the adjacent signatures, a loose back, perforated 'tabs of jaconetor similar material' secured to said lining papers and tov said loose back, and tapes secured to said lining papers and said signatures, and passing' through the perforations in said tabs, substantially as described.
