Illinoisv v Ail-sieaete retrasi-ya, 1948. Sei ial' 6236 riioiiiiml (Cl. 12 13-7 This inventionrelates to index tabs, and one of its objects'is" to providean index tab which may be permanently attached to a file card, separation card or the like' without thefi-u'se of eyelets. rivetsor; similar. fastening means..

Another object is to provide may be made of extruded plastic materialism:

definite lengths?! after which the indefinite lengths .ofmaterial may lee severed into individual-iridexitabs of the requiredlength. v V

Anothe object'is'tcipiovid"anindex tall with aniificli' 'd" r tiorilhavi was wliibh the joblique f aceportioniisfisupporte fby the'upri'ghtslottedwall andbya-diagonally ex: tending brace which joins with the face portion and with the upright wall at its lower edge, thereby providing a face portion which is braced at its top and bottom edges, whereby the face portion is not likely to become distorted by rough handling.

With these and other objects and advantages in view, this invention consists in the several novel features hereinafter fully set forth and more particularly defined in the appended claims.

The invention is clearly illustrated in the drawing accompanying this specification, in which:

Fig. 1 is a perspective view upon an enlarged scale of an index tab embodying a simple form of the present invention and attached to a fragment of a file card;

Fig. 2 is a greatly enlarged view in vertical cross section of the index tab and card taken on the line 2-2 of Fig. 1;

Fig. 3 is a rear elevation of the index tab fastened to a fragment of a card;

Fig. 4 is a rear elevation of a slightly modified form of index tab fastened upon a fragment of a card; and

Fig. 5 is a greatly enlarged detail fragmental vertical section taken on the line 5-5 of Fig. 4.

Referring to said drawing, and first to Figs. 1 to 3 inclusive, which are merely illustrative of one suitable i material; :and; "i1 designates th top and bottom edges thereof 2 embodimeniaof the n en imithe re er nt. e11 acterfi :desi gnatesa fragment-of a iile car aration card or the like usually ofggegt formaand composed of; cardboardgfiber generallyend'preferably composed plastic material sueh' as Celluloidsvin orthe'iik'e.

Face portion 8 is equal in thickness to the upper end portion 15, and is thinner; than the slotted upright wall M. Integrally joined to and extending between the curved edge II and the side portion 20 of the slotted wall I4 is a diagonally extending brace l6 which is of greater thickness than said face portion, and provides a rigid connection between the lower edge of the face portion and the slotted wall. The upper edges ll, [8 of the slotted wall i4 and brace l6 form shoulders that co-operate with the curved top and bottom edges l0 and II of face portion 8 to provide the grooves for receiving the top and bottom edges of an index strip.

The two side portions [9, 20 of the slotted wall M are straight and parallel and receive the upper edge portion 2| of the card 6 between them. The lower edge 22 of the side portion IQ of the slotted wall is beveled 01f as shown and the lower edge 23 of the brace is also beveled off so as to avoid any abrupt shoulders or edges between the card and the index tab.

The edge portion 2| of the card which is disposed in the slot between the side portions I9, 20 of the slotted upright wall is formed with one or more perforations as at 24 and the material or the side portion [9 of. the slotted wall is indented into said perforations as at 25 by any suitable process, thereby preventing the index tab from being pulled off the card except, of course, upon the application of great force.

In the modified form of the invention illustrated in Figs. 4 and 5, the cards (in is formed adjacent its upper edge with an elongated slot 24a which preferably extends parallel with the upper edge of the card 6a, and the side portion 19a of the slotted wall Ha is formed with an elongated indentation 25a which extends through the slot 24a and thus prevents the index tab from being pulled off the card except, of course, upon the application of great force.

The indentations 25 and 25a may be formed by an electronic method, if desired, or may be formed by the application of heat to the index tab and the indentations made with a suitable tool. With the use of the means disclosed for fastening the index tab to the card. no unsightly protruding rivet heads are used.

The index tab may be composed of extruded plastic material of indefinite length severed into individual index tabsof the desired length. If desired, the material maybe tinted, provided the face portion is left transparent so that the index strip therebelow may be easily read.

Having thus described my invention. it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

An index tab for mounting on the edge of a supporting card or the like composed of a single piece of material and comprising a transparent inclined face portion having curved top and bottom edges, a vertically and longitudinally slotted upright wall connected to and extending down from the upper curved edge of the face portion,

said slotted wall being adapted to receive an edge of a supporting card on which the tab is to be mounted and having an upper edge of greater thickness than said face portion forming a shoulder, and intermediate portion of the outer side of the slotted wall being formed as an indentation extending across the slot and terminating adjacent the other side of such wall for engagement with the edges of an opening in such a card, and a diagonally extending brace member of greater thickness than said face portion extending between and merging into the lower edge of the face portion and the adjacent side of the slotted wall, the upper edge of said brace member forming a shoulder, the shoulders formed by the upper edges of said brace member and said slotted upri ht Wall co-operating with the curved top and bottom edges of said face portion to provide grooves for receiving the top and bottom edge portions 01 an index strip.
