INDEX.
sPECIPICATION forming part of Letters Patent No. 370,280. dated September 20,1337,
Application filed January 6, 1887. Serial No. 223,573. (No model.)
To all whom it may concern.-
Be it known that 1, CHARLES S. PERLEY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented an Improved Index, of which the following is a specification.
The object of my invention is to improve the indexing of books-such as Bibles,dictionaries, directories, &c.--so that acomplete index may be presented to the eye no matter on which side the book happens to be lying.
In the accompanying drawings, Figure 1 is a perspective view of a book provided with my improved index. Fig. 2 is a perspective view of the book, looking in the opposite direction to that shown in Fig. 1. Fig. 3 is an enlarged view ofpart of one of the pages.
In books with double-row indexes, as ordinarily made, one row contains the letters A to M and the other row contains the letters N to Z, the first half only being exposed when the book is lying on one side and the latter half only is exposed when the book is lying on the opposite side.
By my method the leaves are cut away, (preferably in a semicircular form, as shownin the drawings,) so as to expose the referenceletteron the first page containing matter under each head, as usual. The several notches of the second column are on a line'or corresponding with the several notches of the first column, and when the reference-letter-say A,
case of N being wanted when the first column of notches are exposed the finger is inserted in the notch opposite A. Similarly, when the second set of notches are exposed and A is wanted, the finger is inserted into the notch or cutting opposite the notch N.
Since by my method each cut at its base has two characters, its own'heading, and that of the cut opposite it,they may be distinguished between by the size or character of the type, their relative positions, or in any similar manner.
Indexes have been made with a duplicate set of the hidden letters on the cover and on each page of the book. This defaces the book, and is expensive; and indexes have also been made with a duplicate set of letters or figures stamped or stenciled on the edge of the leaves in the recesses; but this is objectionable, as stenciling never looks neat and the characters expand when the book is open, and then become difficult to read; but by my improvement very little, if any, more extra expense is GHAS. S. PERLEY.
