Application filed January 10,1980. Serial I0. 419,972,

My invention'relates to an indexed book, a method of producing the same, and a ratus to be used in the practice of the met 0d.

It is customary to index books or files, for

5 ready reference. One method consists in cutting awa the edge of the book to produce a stepped border and to rint letters in alphabetical order upon t e stepped border.

Another method is to cut vlde such edge t the depressions with letters arranged in a1 habetical order. It is also old to secure ta s to the edges of books, with or without the stepped arrangement or deis lost in the-use of such books. Telephone directories, which 'are frequently used, are manufactured as cheaply as possible andit generally customary to equipthe same with an index at the edge.

In accordance with my able to form an alphabetlcal index upon the edge of a book, such as a telephone directory, without materially increasing the costof production of the same by printing the chem, ters or lines upon the pa es 0 the book as theyare being printed, an the characters are so co-related that when the leaves of the book are assembled in the complete book, the albe produced. In connection with the alphabetical index, I rovide phabetical index will depth lines, defining or indicating t e area or thickne'ssof the sections of the book designated by the index letters, thus enabling the user to readily open the book within the proper section designated by-the' index letter.

In the accompanying drawing, forming a part of this. specification, and in which like numerals are employed to designate like parts throughout the same, Fi ure 1 is an edge elevation of a book showing the al formed during t e printin Figure2ris an enlar vation of the edge. of t index letter,

invention, I am habetical' index, which is.

' to cut the ed e book, showing one Figure3 is a. fragmentary side elevation of one leaf of the book, as viewed from line H ofFigure2, p

Figure 4 is a similar view as viewed from line 44 of Figure 2.

In Figure 1, the numeral 26 designates a. book having an alphabetical index formed upon the edge of the same, embodying index letters 27. Associated with these letters'are depth lines 28 and thumb indieating lines 29,- preferably curved, as tory results are obtained by em loying one depth line 28 arranged near and above each index letter 27, although two depth lines may be employed, if desired, as shown 'in conshow'n, Satisfac-.

and associated elements shown in.Fi are formed during theprinting of the book. .To accomplish thls, the le ves of the book, see particularly Figures 3 e d 4, have lines 30 printed thereon, sides of the same, an this rinting extends to the free edgejof the lea The lines 30 throughout: the same alphabetical section or 'unit of the book are in transverse alinement and hence produce, when the leaves are as sembled in the closed. position, the depth line 28, for that alphabetical section, precisely indicating theexact thickness of such section. The in ex letter 27, is produced by printing lines 31, preferably u 11 both sides of the leaves, and u n. asugzsient number of the leaves to pro ace the index letter, the printed lines upon the several leaves being so co- -related that the will produce the index let- (preferably upon both I ter 27 whenthe caves of the book are in the closed position. The thumb indicating line 29 is produced by lines 32, preferably printed upon both ,sides of a suitable number of leaves and these linesv 32 are so co-related that the line 29 willbe prbdueedwhen the leaves are in the closed position. In printing the several lines 30,31 and 82, upon the leaves, at the ed 7 vary nthdeplotmwlthfin the d bl o e eaves, us ren e it'possi e gm e of the book, w1% variations without liab ity of destroying the index.

The printed characters 80, 31 and 82 extend-to or over the free edge of the paper,

' thereon, such lines may limits of the marand since these characters are preferably rinted upon both sides of the sheet,.the

mkthoroughly penetrates into the sheet and and is visible from the same.

Having thus described my inventlon, I

claim I 1. A plurality of assembled leaves produc-' ing a stack, successive leaves having marks upon their faces extending to the ed of the leaves and visible at such edges, t e arrangement of the marks bein such that the assembled marks produce a c aracter.

2. A plurality of assembled leaves producing a stack, some of the successive leaves each having a single mark printed upon the face thereof and other of the assembled leaves each having a plurality of spaced marks printed upon the faces thereof, all of the marks extending to the edges of the leaves and visible at the edges, the arrangement of the marks being such that the assembled marks produce a letter.

3. A plurality of assembled leaves producing a stack, some of the successive leaves having a single mark u on the faces thereof, and other of the assem bled leaves having a pluralit of marks upon the faces thereof all of t emarks extendin to the ed 0 the leaves and visible at t e edges, t e arrangement of the marks being such that the assembled marks produce a letter, said leaves bein also provided with separate marks extending to the edges thereof, and arranged near the letter, the separate marks when assembled producin a depth auge.

In testimony w ereof I a my signature.

FRANK ELLISON.
