Be it known that we, ANsoN O. KITTREDGE, residing at 42 Leyfred Place, Springfield, county of Hampden, State of- Massachusetts, and ERNEST R. KITTREDGE, residing at 128 East Twelfth street, in the city, county, andV State of New York, citizens of the UnitedV States, have invented certain new and useful Improvements in Book-SectionsHaving Wide Io and Narrow Leaves, fully described and represented in the followingspecification and the accompanying drawings, Yforming a part of the same.

The present application is a division of application No. 727,717,-filed August 18, 1899,

with title Book-sections having wide andA and other books having wide and narrow leaves. Such books when used for'accounts 3o and records of Various kinds frequently require to be ruled in columns with headings printed upon the various columns orv pages.

In most books having wide and narrow leaves a certain number of narrow leaves is bound. intermediate to two of the wide leaves, and

the narrow leaves are used in connection with a record or inscription upon the projecting margins of the wide leaves. It is found in practice that the demands of various busi? so.` nesses requirewide variations in the number of narrow leaves for usein connection with each of thewide leaves, and as such requirements cannot be anticipated so as to keep the books instock we have devised meansv for preparing unit sections with a group of the narrow leaves and a single wide leaf, so that such sections may be quickly bound into books of various dimensions.-

' to form a book-section.

In practicing the invention we form the narrow leaves in pairs, which vmay beinserted 5o within yone another, and we form the wide leaf iny connection with a narrow leaf from a single sheet of suitable width, the pairs of narrow leaves being inserted within the fold of such sheet and the whole secured together Any number of the pairs of narrow leaves Vcan be inserted within the fold of the sheet which, ,constitutes the wide and narrow leaf, and books Ain great variety can thus be made at shortV notice from 6o the same materials previously prepared. By this method narrow leaves can be combined with wider leaves of any desired width, and wide leaves of a given width can be combined with narrow leaves of any desired width. 6:

` The edge of the wideleaf can be reinforced by any of the ordinary means to correspond with the thickness of the annexed group of narrow leaves inthe same section and the book be thus made of uniform thickness in 7o the edge and in the body. By this method of forming book-sections the sheets of paper can be ruled and printed before folding and canthen be combined at short notice to pro'- duce the books desired.

The invention will be understood by reference to the annexed drawings, in which-jA Figure I is an end view of an open book with the leaves separated` at the left side to show the disposition of the wide and narrow 8o leaves. Fig. v2 represents in perspective a pair of the narrow leaves for such book formed from a single sheet. Fig. 3 represents a wide and narrow leaf formed from a single sheet. Fig. 4 is an end view Iof one of the wide and 85 narrow leaves with a group of'three pairs of the narrow leaves inserted within the fold of the same. Fig. 5 is an en dviewofsix sec tions constructed as shownin Fig. 4.

a designates the narrowleaves, b the wide 9c leaves, and c a iiap folded upon the edge of the'wide leafto forma pocketl for the inser-A tion of a thickener. Two narrow leaves are shown in Fig. 2, formed by once folding a sheet of paper of suitable width.v A wide leaf ZJ and narrow leaf ct are shown in Fig.

3, formed by folding a wider sheet of paper, the paper having also sufcient width to turn the flap c over upon the edge of the wide leaf if an integral iiap is desired.

It is immaterial to the present invention how the `edges of the wide leaves be thickened. The visible surfaces of the Wide and narrow leaves are shown ruled, and such ruling is readily eected, and columns ruled upon the sheets and headings printed in the columns, if desired, before the sheets are folded.

Fig. 4 shows in the outer leaves a b a pair of wide and narrow leaves,like the pair shown in Fig. 3, excepting that the thickener is shown upon the right-hand leaf instead of the left, and three pairs of the narrow leaves a are shown inserted in the fold of the outer leaves. Pairs of the narrow leaves to any required number may be thus inserted, and the folds of all the leaves of such group are readily stitched or secured together to form a unit or section, and any of such unit-sections may be bound with other similar sections to form a book which necessarily has, as shown in Figs. l and 5, au odd number of the narrow leaves between the adjacent wide leaves.

An independent line h is shown at the left side of the group of sections in Fig. 5 to indicate a fly-leaf or printed leaf to complete the book, if necessary.

From the above description it will be 0bvious that sections or units of different character may with the same facility be just as readily made and combined in the same book as sections of uniform character.

Vhere books require uniform printing or ruling, but vary in the number of leaves in the diiferent units, the leaves may be made by printing and ruling sheets of suitable size and then folding such sheets to form integral pairs of the narrow leaves and of the conjoint wide and narrow leaves and carrying the same in stock until a given book is ordered and the required capacity of the book is known.

It will be understood from the above description that each section necessarily con- Jrains an even number of leaves and that one of the leaves being a wide leaf the number of narrow leaves in each section is necessarily an odd number. The construction is thus distinguished from all of those in which each signature or section has narrow leaves formed from a single sheet folded repeatedly, as the repeated folding of such a sheet would necessarily produce an even number of the narrow leaves.

This invention furnishes great facility in making account-books from stock previously prepared, and thus enables orders to be filled with much greater despatch than where the ruling, printing, and folding of sheets must be done before a book can be made, as the sheets can be ruled and printed in advance for many such classes of books and the proper number of narrow leaves readily combined with each of the wide leaves by the arrangement above described.

Having thus set forth the nature of the invention, what is claimed herein is A book having wide and narrow leaves and formed of unit-sections with an odd number of narrow leaves in each section, and each section comprising a wide and` narrow leaf in one piece with a group of narrow leaves in pairs inserted in the fold of such wide and narrow leaves, and the projecting margin of the wide leaf being reinforced to agree in thickness with the other leaves of the section, substantially as herein set forth.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
