COMBINED BOOK AND INDEX.
SPECIFICATION forming part of Letters Patent No. 408,260, dated August 6, 1889.
Application filed February 28, 1889. Serial No. 301,462. (No model.)
To all whom it may concern.-
Be it known that I, HENRY E. PRATT, of Lambertville, in the county of Hunterdon and State of New Jersey, have invented certain new and useful Improvements in a Combined Book and Index and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will e11- able others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in a combined book and index.
The object is to provide an index which may be at all times accessible for purposes of reference, and in which the leaves may be turned without conflicting with the turned same time to so connect the index with the book as to insure its permanent attachment thereto under any ordinary usage during the life of the book.
A further object is to provide an index and its connection with a book which shall be simple, convenient, and quite inexpensive, and which will admit of the index being folded flatly between the cover and last leaf of the book.
lVith these ends in view, myinvention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 shows the index and book both open, as in position for use; Fig. 2 is an end View showing the index partially folded, and Fig. 3 is an end View showing the index folded within the book.
In the present case the index is shown in combination with what is commonly known as the Chadwick copying-book; but its use is not limited to this or any other specific construction, except so far as the cover of the book serves to form the means for connecting the index thereto.
A represents the body of the book or its leaves, and 13 represents the cover of the book. In the style of book herein illustrated the cover B is canvas, rendered stiff at the front and back of the book by sheets of paper-board.
The cover B, either at the front or back free edge, in the present instance at the back, is extended away from the book a distance equal to the width of the index, or a little more, and to the free edge of the cover so extended the back edge e of the index 0 is hinged. The extended portion B of the cover has a flexible joint I) at the edge of the book cover proper, and said extended portion is preferably stiffened by a suitable lining of thin paper-board. The joints at Z) and c are preferably re-enforced by strips (Z of fabric glued on their inner faces. The index 0 is provided with thin paperboard covers E and E, the former stopping short at its free edge the width of the column of initial-letters of the index, while the latter projects underneath said column and protects the outer edges of the leaves against wear when the book is open and its index extended as in use.
By the above construction the index may be folded within and adjacent to one of the covers of the book,with its index, or, rather, the initial-letters of its index, at all times exposed, while the leaves of the index may be turned backwardly toward the free edge of the book proper and the leaves of the book proper turned toward the index without in the least conflicting therewith. It will be further noted that the prolongation of the book-cover forms a cheap, neat, and durable means for the attachment of theindex, does away with the necessity of any clumsy device or devices foreign to the material employed in manufacturing the book, saves the shaping and attachment to the book of an intern1ediate separable piece, and admits of a compact and neat closure of the index and its connecting-piece within the cover of the book proper.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination, with a book having one of its covers extended to form a folding extension, of an index hinged at its back to the free edge of the extension, substantially as set forth. u
2. The combination, with a book having its cover extended beyond the edge of the book, of an index having its back hinged to the free edge of the cover-extension and provided with a cover of less width than the said cover-extensio1'1, substantially as set forth.
3. In combination, a book, an index provided with a back and front cover, the front cover being narrower than the back cover to expose a column of initial-letters, and a projecting portion of the book-cover connecting the index With the book and forming flexible joints at the front edge of the book and at the back edge of the index, whereby the index may be folded Within the cover of the book With its column of initial-letters at all 10 times exposed, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
HENRY E. PRATT.
