APPLICATION FILED MAY 7, 1917.

INDEX.
To all whom it may concern.
Be it known that I, JOSEPH KAHN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Indexes, of which the following is a specification.
My invention relates to improved index tabs and improved forms of strips from which individual index tabs may readily be torn or out.
My invention concerns particularly index tabs to be pasted at the edges of the leaves of accounting books, files, etc. Heretofore such index tabs originally formed part of a single strip from which they could be torn along perforated lines or out therefrom. In the case'of the alphabet characters all the character tabs formed part of a single long strip or several strips. The long strips were not practical and with shorter strips more or less time is wasted to find that strip which had on it the particular tab desired. One important object of my invention is therefore to produce double strips along the sides of which the various tabs are arran ed. For example one-half of the alpha et character tabs would be at one side of a strip and the'other half along the other side, with a perforation line running down the center of the strip and the individual tabs defined by cross cuts which extended to within a short distance of the center perforation line so that the individual tabs could be turned from the strip. Another object of the invention is to produce a tab from which the diagonally opposite ends of the glued flaps can be readily removed in order to decrease the weight and also to decrease the thickness where tabs overlap. Another object is to provide improved cross cutting arrangement of a double strip to permit tabs to be readily severed therefrom and their diagonally opposite corners removed.
My improved construction and arrangement is clearly disclosed on the accompanying drawings, in which Figure l is a front side elevational view of a double strip,
Fig. 2 is an enlarged sectional view on plane 2-42, Fig. 1,
Fig. 3 shows the section of a double strip with a modified perforating arrangement.
Fig. e is a front side view are doub Specification of Letters Patent. Patented NOV, 20, 191?. Application filed Ma z, 1917. Serial No. 186,834. I
strip showing my improved of cross cutting, g Fig. 5 is a perspective view-of a tab removed from the strip "of Fig. 4, and '1 F ig, 6 shows a tab like that of Fig. '5
with the diagonally opposite corners cut away, and the tabs applied" in overlapping relation on the leaves of a book.
Referring to the double strip of Figs. 1
and 2, a strip 10 'preferably'of leather is to bring the end sections 13 and '14 parallel with the back of the strip and to within a short space 15 of each other in front of the center line of the back. In the folds stiffening strips 16 and 17 of .paper, leather or other suitable material are inserted and secured as by means of glue to the strip material, the inner faces of thefree ends 13 and 14 in front of the stiffening strips and the front face of the back of the strip being.
in Fig. 1, onelside of the strip has one half arrangement I foldedalong longitudinal lines' 11 and- 12 I of the alphabet characters and the other side the other half, and preferably the characters on one side of the strip appear. in the upper outer corner of the tab and on the opposite side of the strip and same characters appear at the lower outer corner of the respective tabs in order that tabs may be applied to leaves in overlapping arrangement. The double strips can be as readily manufactured as the single strips and aremuch more easily handled.
Instead of having small perforations as along line 18 in Fig. 1, the back of the strip may be provided with a line of longer slits 23 which come to within short distances of each other, as clearly shown in Fig. 3.
In Fig. 4 the slitting arrangement is such that tabs can readily be cut from the double strip and the diagonally opposite corners of the glued flaps readily cut away. Trans? verse slits 2 L extend from the left edge of the double strip up to the inner edge of the.

and the transverse slits 25 extend from the right edge up to the inner edge of the stifiening strip 17 along the left edge, the slits from one edge extending midway between the slits from the opposite edge. In other words, the slits 24: define the upper and lower boundaries of the tabs at the left side of the strip and the slits 25 define the upper and lower boundary lines of the tabs at the right side of the strip, the left side tabs being vertically offset from the right side tabs and the walls of the tabs inside of the stiffening strips being bisected. If a certain tab is now desired the back of the strip is out along its middle line to release the tab desired, a removed tab being shown in Fig. 5, and has the four flat sections a, 6, c and (Z having glue on their inner faces. In order to reduce the weight and also to reduce the thickness at the sheet edges when the tabs are overlapped, the diagonally opposite flaps are preferably cut away. For example, in Fig. 5 the diagonally opposite flaps a and cl would be removed by cutting along the inner edge of the stiffening strip 16. The inner faces of the remaining flaps b and 0 would then be moistened and the tab applied to the edge of a sheet 6 as shown in Fig. 6. Then, where the tabs overlap, as shown, there will be only two thicknesses of flaps instead of four as would be the case if the diagonally opposite flap sections were not cut away.
The double strip construction has been found to be much more practical and desirably less than that for two single strips. Furthermore, the cross cutting enables the strips to be compactly folded for shipping I by mail or otherwise.
Having described my invention, I claim as follows:
1. A double tab strip comprising a strip of fabric folded longitudinally substantially midway between its center line and its outer edges, stiffening strip inserted in the folds, and cross cuts for subdividing the strip into tabs.
2. A double tab strip comprising a single piece of leather or fabric folded longitudinally substantially midway between its cen ter line and the side edges, stiffening strips secured in the folds, perforations along the center line of the double strip, and cross cuts extending from the side edges of the double strip to within short distances of the center perforation line whereby said double strip is subdivided into tabs readily torn therefrom.
3. A double tab strip comprising a single piece of leather folded longitudinally sub stantially midway between its center line and the side edges, stiffening strips secured in the folds, and cross cuts extending from the side edges of the double strip up to substantially said center line.
In witness whereof I hereunto subscribe my name this 1st day of May, A. 1)., 1917.
JOSEPH KAHN.
