METHOD OF MAKING INDEXED BOOKS.

SPECIFICATION forming part of Letters Patent No. 359,469, dated March 15, 1887.

Application filed January 8, 1886. Serial No. 18,007. (No model.)

To all whom it may concern.-

Be it known that I, EZEKIEL O. M. RAND, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful'lmprovements in the Method of Making Indexed Books, of which the following is a specification.

My invention relates to the manufacture of that class of books in which the margins of the leaves are cut away to leave tongues provided with letters, figures, signs, or words, and constituting an index,facilitating reference to the different parts, sections, or classes of the book; and my invention consists in printing each signature of the book with lines of indentations or perforations, and in folding the signatures and tearing or cutting away the paper tongues in proper position to receive and leave exposed the index letters, figures, or signs.

My invention further consists in printing the lines of indentation or perforations and the index-signs upon the portion of the leaf which constitutes the tongue and then folding and removing the portions'outside of said tongue. In the drawings, Figure 1 is a perspective .view representing a blank book indexed in the usual manner. Fig. 2 is a plan of signature illustrating the description of the invention. Fig. 3 is a plan of a signature illustrating my improvement. Fig. 4 is a perspective view illustrating a printed pamphlet or book constructed in accordance with my invention.

In the manufacture of reference-books having marginal lettered or numbered index tongues or projections, as shown in Fig. 1, it has heretofore been customary to cut the leaves by hand or machine after the book is bound,

'to leave the superfluous portions, constituting the tongues a, and to then print the signs upon the tongues, or apply to the latter pasted slips having the said signs printed thereon. This mode of manufacture is slow and-for books containing much matter of various classesvery expensive, and frequently results in mistakes in cutting the leaves, which injure or destroy the books. The use of cutting-machines in the manufacture of such books has heretofore proved to be impracticable, because of the fact that there are a number of leaves upon a single signature, which must be folded prior to binding, and the cutting of the signature in order to form the tongues a, preliminary to such folding, would result in separating the leaves, so that they could not be effectively bound together; and, moreover, it would then be necessary to subsequently print or paste the signs upon the tongues.

Thus if the signature A, Fig. 2, were cut bya machine prior to binding, it would be reduced to a shape similar to that showmwhich would render it impossible to properly fold it. In order to avoid these objections, I arrange the the usual manner, and, in addition,I arrange a series of scoring or perforating rules, so as to perforate or weaken the sheet upon the lines m, Fig. 3,without separating the same at any point, and I also arrange type so as to form or print index signs or matter upon the page portions of the signatureadjacent to the scored lines. Thus when the book is to have marginal 'index matter upon two of the margins-for instance, the edge and bottom of each page-the indenting-rules are arranged so as ordinary type matter to print a signature in to form lines of indentation at right angles to each other and terminal transverse scores y, and the index matter is printed upon the paper at points outside of the scores y, after which the signature is folded and bound with the other signatures, when the portions outside of the lines it y may be readily removed from said lines without measurement, leaving tongues a, Fig. 4, upon the side and lower edges of each sheet, and with index matter, either letters, numerals, signs, or words, upon the tongues.

It will thus be seen that by this mode of manufacture the lines upon which the leaves must be divided are so positively fixed that there can be no possible mistake in removing the surplus matter, and the removal can be effected without the use of cuttingtools withabsolute certainty and precision. The indexbook and whatever may be the character of the index-signs, and that it is applicable to both printed or partially printed and blank books.

It will of course be understood that when the book is made of a number of signatures the scored lines at 3 will be differently placed upon each signature,aeeording to the position which the latter is to occupyin the completed book, and that the scoring or perforating may be done in a machine separate from the press, although it is desirable in most instances to effect both operations at the same time.

Ihave referred only to one side of the printed Signature, which, of course, can be generally printed upon both sides, and I have indicated the position of the scored lines and other matter upon opposite sides in Fig. 8 by full and dotted lines.

1. The within-described improvement in the manufacture of books having marginal iuden and classification matter, the same eonsisting in perforating, marking, or indenting the signature before it is folded upon lines defining the portions to be removed and in then folding the signature and removing the portions outside of said lines, leaving projecting tongues, substantially as set forth.

2. The within-described improvement in the manufacture of books having marginal tongues with index or classification matter thereon, which consists in first printing each signature with lines of perforations, markings, or indentations defining portions to be removed,and with index-signs upon the margins and then folding the signature and removing the portions outside of the said lines, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
