Letters P11-tent No. 100,994, dated March 2.2, .1870.

The Schedule xeferred to :ln these yLettere Patent and making part of the same.

To all whom it may concern; y

Be it known that we, CHARLES A. FITCH, of San Francisco, county ot' San Francisco, and WILLIAM 0. Sr, JOHN, of Oakland, county of' Alameda and State of California, have invented an Improved Ledger-Jndex; and we do hereby declare the following description and accompanying drawings are suiicient to enable any person skilled in the' art; or science to which it most nearly appertains to make and luse 'our said invention or improvements without further invention or experiment.

The object of our invention is -t`ov provide a ready and convenient index-book, which is arranged with ruled pages, each sheet being suiiciently stiff to support itself, so that when it is raised it willstand vertically in front of' the .book-keeper or accountant in a com'enientposition to display the names written upon it' is had to the accompanying vdrawings forming a part of this specification, in whichf l A represents our index-book. This book consists of a number ot' sheets, B, made of 'card-bard or other In order to better illustrate our invention, reference suitable paper, munberiug'at least as many as there are letters in the alphabet. Between each of these sheets may be placed an intermediate sheet or pasteboard, a. l

The intermediate sheets a are. somewhat longer 7than the sheets B, and are placed in the book in such a position `that the extra length of each will project4 altogether at one end, while the other end is flush with the ruled sheets.

The whole is then bound with asuitable cover, which protects the two sides, the back, and one endot the book, the extra length of thelintermediate sheets be-A ingbound together at the`end C. A

A bolt, or rivet, b, passes through the lower corner of thc unbound end ofthe book, passing also through the corner of each of the leaves or sheets B, thus leaving them simply held by the bolt.

Secured at some convenient point, and in the most convenient order along the upper edge of the sheets A, are small metallic or other suitable tags, marked as in the drawings, with the letters 0i the alphabet from A to Z. By grasping either of these tags and drawing upward upon it the sheet to which it is at-v tached is li'tedand turned unt-il it stands upon the pivoted end, bringing itsentire length directly' before the accountant. a

The naines ofthe persons havin gledger a( counts and the number of the pages uponwhich they occur-'are written upon the sheets B, being alrangedupon the pages by letters according to the usual way of forming a ledgerindex, Which-can be done by taking out the bolt b and removing the sheets, and afterward re'- turning them to their proper places.

The sheets B may be ruled or not, as most convenient. n

By constructing an index-book in the above-described manner a greatsavingof time is obtained, while all danger of soiling the ledger itself by turning so frequently to the index, as is usual when the index .is made a part of the ledger, is obviated.

The book' presents a 'neat form, and can be readily opened and closed to any letter of the alphabet.

What we desire to secure by Letters Patent isl. An index-book having the sheets B pivoted as shown, and provided lwith the alphabetical tags, substantially as described. .4

2. The arrangement of the pivot b at the lower corner of the book, whereby the sheet raised stands upon and is kept iu position by the surface of the desk or table, and the whole length of the sheet presented to view, substantially as described.

. In witness whereof we have hereunto set our hands and seals.
