Applieantion November 30, 1931, Serial No. 578,099

3 Claims.

This invention relates to index tabs and particularly to that class of tabs adapted to be applied to card index leaves or book leaves, not originally so equipped.

The present invention comprehends an index tab having a substantially U-shaped outer or index strip and an attaching member of similar shape having a fold portion inserted between and secured to the edges of the index strip, the

space within the interior of the index strip providing a pocket for receiving an index slip, or like element, containing index indicia. The innor surface of the U--shaped attaching member is coated with adhesive material adapted to secure the tab to a paper sheet or other article to be indexed.

According to the present invention the at taching member and index strip are formed of flexible transparent material, for instance, celluloid, cellophane, or the like, in order that sulting in better adherence to the article to be indexed, and also permits observation of index indicia upon an index slip placed in the tab. lhe indicia bearing index slip preferably comprises a folded strip having diverging leg portions en- ","3 0 gaging the sides ofthe index strip adjacent its attachment to the attaching members. The invention provides a shield strip extending longiz'tudinally on the inner side of the fold portion :of the index strip providing an engaging memher for the upper edge of the indicia bearing index slip and providing a cover for the upper edge of the index strip to conceal the outer edge from view.

The index tabs may be formed in strips of 4- indefinite length and may be cut up into smaller sections by the user, to accord with his particular needs, and may then be applied by him to the edges of the leaves of books, index cards, or like material which is to be indexed.

In the drawing: Fig. 1 shows a guide card and the improved index tab thereon in perspective.

Fig. 2 shows the composite tab structure in strip form in perspective with one end portion of the index strip detached and turned back to show the attached shield.

Fig. 3 is a cross section substantially along the lines 3-3 of Fig. 1, showing the index tab applied to a guide card, with an index slip insorted in the pocket.

As shown in Fig. l, the index tab generally indicated at 10, may be applied to an edge portion of an articleto be indexed, such as the leaf or guide card 11. An attaching member 12 includes substantially parallel sides 13 and 14 that are integrally vjoined by an intermediate fold portion 15. The attaching member is formed of flexible transparent material, for instance, celluloid, cellophane or the like, in order that indicia may be visible therethrough and adhesive 16 applied to the inner surfaces of the index strip, is likewise transparent, it being of a type adapted to secure the strip 12 to paper or other articles to be indexed, either in its applied condition or upon moistening.

The index strip 1'7 is of substantially the same form as the attaching member 12, having side portions 18 and 19, respectively, which are integrally joined by a fold portion 20. Marginal edge portions 21 and 22 of the respective sides 13 and 19 of the index strip are joined to the sides of the attaching member 12 adjacent the fold portion 15 of the latter, the edge portions being provided with a transparent adhesive whereby the index strip may be attached to the attaching strip member or to material to be indexed. A space or pocket is thus provided between the fold portions 15 and 20 of the attaching and index strips and between the walls 18 and 19 of the index strip, for the insertion of an index slip 23 which may comprise a strip of paper folded longitudinally to provide diverging legs 24 and 25 for frictionally engaging the walls 18 and 19 of the index strip to retain the strip against disformed of transparent material, for instance,

transparent celluloid, or strip material formed from cellulose ester, or the like transparent substance.

A shield strip 27 is placed longitudinally of the inner side of the fold portion 20 of the index strip having edges 28 substantially parallel to the edges or the index strip 17. This disposition of the shield strip forms a frame member limiting and defining the upper limit of visibility of index information carried upon the index slip 23.

The shield strip 27 provides an engaging surface for contact with the upper edge 29 of the index slip, which, together with the contact of the edge portions of the diverging legs 24 and 25, irictionally retains the index slip within the pocket between the fold 15 of the attaching member and the sides 18 and 19 of the index strip.

The provision of the strip permits the production of a tab of indefinite length which may be cut in any desirable width and applied to a card or leaf or the like as the user may wish, and a strip which is adapted to retain an index slip therein against inadvertent displacement. The shield may be colored in a variety of ways, if desired, for enhancing the appearance of the tab as well as facilitating use of the tab in indexing.

I claim:

1. An index tab comprising an elongated strip of transparent sheet material formed to provide a pair of spaced substantially parallel side sections and a connecting fold section, means on the free marginal portions of said side sections for securing said tab to the margin of a sheet, said means cooperating with said side sections to define one side of an open ended label receiving pocket therebetween, and a shield strip mounted on the inner side of said fold section, extending longitudinally of said tab, having the edges thereof terminating in spaced parallel relation to said means and cooperating with said means to define that portion of said side sections through which a label is displayed, said shield strip and said means cooperating with the opposite edge portions of a label in said pocket for normally retaining said label therein.

2. An index tab comprising an elongated strip of transparent sheet material formed to provide a pair of spaced substantially parallel side sections and a connecting fold section, an attaching member formed with a pair of spaced substantially parallel side sections and a connecting fold portion inserted within the marginal edge portions of said strip, a transparent adhesive between and connecting said portions, a shield strip mounted on the inner side of said fold section extending longitudinally of said tab having the edges thereof terminating in spaced parallel relation to said attaching member and cooperating with said attaching member to define that portion of said side sections through which a label is displayed, said shield strip and said attaching member cooperating with the opposite edge portions of a label placed between the edge of said strip for normally retaining the label therein and a transparent adhesive upon the inner side of the side sections of said attaching member.

3. An index tab comprising an elongated strip of transparent sheet material formed to provide a pair of spaced substantially parallel side sections and a connecting fold section, means on the free marginal portions of said side sections for securing said tab to the margin of a sheet, said means cooperating with said side sections to define an open ended label receiving pocket therebetween, and a shield strip extending longitudinally of said tab mounted in said pocket, engaging in said connecting fold section having at least one of its edges terminating in spaced parallel relation to said means and cooperating with said means to define the label displaying region of the respective transparent side section, said shield strip providing means cooperating with the edge portion of a label inside the pocket for normally retaining said label therein.
