INDEX-TAB.

sPECIFICATION forming part of Letters Patent N 0. 681,521, dated August 27, 1901.

Application filed April 16,1901. Serial No. 56,074. (No model.)

To aZl whom it may concern:

Be it known that LMARY' O. TREssEL,a citizen of the United States, residing at Canton, in the county of Stark and State of Ol1io,have invented a new and useful Index-Tab, of which the following is a specification.

My invention relates to an improved indextab to be attached to the leaves of books to definitely designate certain pages thereof or the divisions between the various subjectsmatter therein; and the object of my improvement is to make a tab that can conveniently be affixed to the leaf of a book by an ordinary user whenever it is desired to mark the same in a quasipermanent manner. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is an isometrical View of an open book with the indextabs applied thereto; Fig. 2, an isometrical view of the fragment of a leaf and the parts of the index-tab in relative position for attaching thereto; Fig. 3, an isom'etrical view of the same parts being brought together; and Fig. 4 an isometric view of the same parts, showing the attachment complete.

Similar numerals refer to similar parts throughout the several views.

I have illustrated the index-tab with reference to its use in designating the respective accounts in an ordinary ledger 1, so the same can be readily located.

The index-tab 2 is cut or stamped out of a thin sheet of stiff but elastic or flexible material, preferably of dull-faced celluloid or a suitable metal, and is composed of a projecting part 3, extending outside the edge of the leaf, and an engaging part 4, contiguous to the side of said leaf at the edge thereof. In opposite sides of the engaging part 4 are formed the tongues 5, the sides thereof being out free from the contiguous parts, the bases thereof being continuous .with said engaging part and the end of said tongue being preferably pointed or rounded, as illustrated. The plate 6 is preferably made of a sheet of the same material as the tab 2 and of the same size and shape as the engaging part thereof. The slots or apertures 7 are provided therein in the same relative positions as the respective bases of the tongues 5. These slots are preferably made as long'as the tongues 5 are wide and somewhat wider than the thickness thereof.

To attach the index-tab to the leaf 8 of the ledger 1, the slots 9, similar in size and rela tive position to the slots 7 of the plate, are cut in said leaf near its margin at the proper place for the tab. These slots, having been located by using the plate 6 with its slots 7 as a stencil, can easily be cut with an ordinary penknife or by a punch having its cut ting-die suitably shaped for the purpose. The parts are then brought together by placing the plate 6 against the leaf 8 with the respective slots 7 and 9 in line with each other, through which are inserted the rounded ends of the respective tongues 5, said tongues and the remainder of the tab 2 being bent as much as necessary for that purpose, as illus 7o trated in Fig. 3. The attachment is completed by pushing the tongues 5, respectively, through the slots until the engaging part 4t of the tab is in contact with the side of the leaf 8 opposite the plate 6, when the tongues 5, if made of elastic material, will flatten out against the plate 6, or, if made of a flexible material, are flattened out against said plates, as illustrated in Fig. 4. The index-tab can be detached from the leaf at any time, if so desired, by merely reversing the process. Otherwise it will remain firmly attached to the leaf in a practically permanent form and in a strong and substantial manner. If the leaf of the book is made of a specially thick 8 and strong paperfithe index-tab can be attached thereto without using the plate 6; but for practical purposes and to protect the leaf from wearing and tearing I prefer to make the attachment as described.

Before or after attaching the tab a suitable inscription is made on either side or both sides of the projecting part 3 to properly index the particular page or part desired to be designated, and to designate in a general way 5 the different subjects-matter of the bookas, for instance, the different classes of accounts carried in a ledger-tabs of various colors may be used.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An index-tab for the leaf of a book composed of a projecting part agd an engaging were;

lar slots near its edge, said tongues being adapted respectively when bent to pass through said leaf-slots and plate-slots successively, and when straightened to attach said tab and plate to the leaf, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MARY 0-. TRESSEL.
