UNITED STATES PATENT OFFICE.

GEORGE A. PRATT, OF BROIVNSVILLE, CALIFORNIA.

BOOK INDEX AND CASING.

SPECIFICATION forming part of Letters Patent No. 422,971, dated March 11, 1890.

Application filed June 20, 1887 Serial No. 241,934. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE A. PRATT, a citizen of the United States of America, and a resident of Brownsville, Yuba county, State of California, have invented new and useful Improvements in Book Indexes and Casings, of which the following is a full, clear, and exact description, referring; to the accompany ing drawings.

The object of my invention is to construct a ledger or other book requiring an index, with a suitable casing having a drawer Wherein the separate index-book is placed; or I may do without a drawer and place the index-book directly in the casing. I construct my casing in such a manner that the index-book can be examined without opening the book.

Figure 1 is a perspective View of the ledgerbook, showing the book closed with the drawer out and the index-book open. Fig. 2 is a vertical section of the same when closed.

To the inside of the cover of the ledger or other book A, I suitably secure a suitable casing B. This casing has an open end, through which the drawer O operates within the casing and wherein it may be secured by means of a suitable knob and catch or lock E. \Vithin this drawer I place the separate indexbook D; but I do not confine myself to the use of a drawer wherein my index-book is placed, as I may do without a drawer and place the index book directly into the casing B, in which condition the lower cover of the index-book may be constructed wider than the upper cover and the index-book for the purpose of holding by this wider section of the cover the index-book to the sides of the casing B.

In operating my device I lay the ledger book on the table with the casing B nearest the table, and by taking hold of the knolr catch E, I am able to pull the drawer C suf' ficiently out to enable me to open and examine the index-book D without taking the same from the drawer or opening the ledger-book.

In case I desire to examine the index-books of several of my improved ledger-books which are piled on top of each other,tl1enI pull the drawer of each book out and examine the index-book without disturbing the large books.

I am aware that a photograph-album has been provided with a receptacle in one of its covers, and such matter is not of my invention.

Having thus fully described. my invention, what I claim, and desire to secure by Letters Patent, is

I. The book A, having casing B and a drawer (3, substantially as and for the purpose set forth.

2. The book A, having casing B, drawer O, and an index-book D, substantially as and for the purpose set forth.

3. A book having a casingin its cover closed on both sides and open at the front edge of said cover, the casing being adapted to receive the index without moving the book or its cover, substantially as described.
