INDEX TAB.

Application filed May 2,

To all whom it may concern:

Be it known that I, JAMES H. RAND, citizen of the United States of America, and resident of North Tonawanda, in the county of Niagara and State of New York, have invented new and useful Improvements in Index Tabs, of which the following is a specification.

This invention relates to index tabs for cards, and consists in the novel and improved features hereinafter described and particularlypointed out in the claim.

In the accompanying drawings which illustrate certain embodiments of the inven- -tion Fig. 1 is a front view of a preferred form of the index tab;

Fig. 2 is a cross section on line 22 of Fig. 1;

Fig. 3 is a similar cross section of the'tab applied to a thinner card;

.Fig. 4 is a cross section of a modification;

Fig. 5 is a cross section of a further modification; and

Figs. 6, 7 and 8 are "diagrams hereinafter explained, illustrating the manner in which the tab conforms to cards of vary-ingthickness.

The card 1 may be itself a record card, orit may be a guide or divider card such as is commonly placed between groups of folders or other indexed matter, and may be of usual form and material.

The index tab is made of a stri of sheet material, preferably sheet celluloi or some other transparent, resilient material, doubled upon itself to form a front leaf 2 and a real --ieaf 3. The interior of this doubled strip constitutes a pocket adjacent the fold 4 and between the front and back leaves, adapted to receive a removable index slip 5 on which may be inscribed a name, numbers, letters or other suitable indexing characters. The fourth side of the pocket is defined by the upper edge of the'card 1, when the tab is applied to the card as hereinafter explained. The pocket is open at each end to permit the insertion and removal of the index slip 5.

Both leaves 2 and 3 are similarly bent in a rearward direction along lines 6 and 7 running widthwise of the tab and substantially.

1921. Serial No. 466,133.

made of textile fabric or'other suitable material having a gummed surface by which the bent over margins 10 and 11 of the two leaves are cemented to opposite sides of the card.

In applying the tabto the card the gummed attac ing strips 8 and 9 are moistened and the edge of the card'l is inserted between them until the edge of the card comes against the bend 6 of the front leaf. The bend 6 acts as a stop for the edge of the card and so positions the tab on the card and determines the extent of. the projection of the tab beyond the edge of the card. The attaching strips 8 and 9 may project beyond the edges of the leaves as shown in Figs. 1 to 4, to insure a more secure attachment;

or the attaching strips may lie wholly within the area of the leaves of the tab as shown in Fig. 5. r In the latter case it will be desirable strip 5, which is displayed through the transparent'tab, in a convenient position for reading from the view point of the user which is normally above the index.

The fold 4, is preferably rounded so as to space the front and rear leaves 2 and 3 I far enough apart to form a pocket of suit able depth for the index slip 5. The rounded fold 4 also forms a bow spring adapted to press the two leaves togeth'er and hold the free margins of the leaves against the card with considerable pressure thus contributing to the firm attachment of the tab especially while the cement is setting.

The resiliency of the sheet material of the tab also permits the tab to be applied to cards of different thicknesses with its bent free margins lying flatwise or parallel to the surfaces of the card. By way of illustration, the diagram of Fig. 6 shows the tab applied to a card 1 of the same thickness as the spacing of the leaves adjacent the fold 4; the diagram of Fig. 7 shows the tab applied to a card 1 of less thickness than the spacing of the leaves adjacent to the fold 4; and the diagram of Fig. 8 shows the tab applied to a card 1 of greater thickness than the spacing of the leaves adjacent to the fold 4. In each instance while the front and back walls of the (pocket may be parallel, or converge, or iverge, as the case ma be, the free bent margins are parallel an lie flat against the card. The structure of Fig. 3 difi'ers from that of Figs. 1 and 2 in that the tab is a lied to a thinner card. The structure of ig. 4 differs only in that the bends 6 and 7 are nearer the fold 4, thus producing a lower tab projection and a narrower pocket, which may be preferred for certain uses. And the structure of Fig. 5 differs in that the attaching strips terminate at the edges of the leaves, and one leaf is a little longer than the other for the reason already explained. .The tabs may be made in any desired length and may be applied to the cards by the manufacturer and sold as a component part of the card to the user. .The invention is peculiarly adapted however to be a plled by the user to cards which he may a ready have in use in an existing index. When used for this purpose the folded tab structure may be made and sold in lengths of any desired extent, adapted to be cut up by the user into shorter lengths or sections according to the lateral width of the tab desired. To attach the tabto a card the user has merely to moisten the gummed attaching strip and apply it as shown to the edge of the card until it comes to a stop with the edge of the card against the bend 6, which determines the correct positionin of the tab in a. vertical direction on the card. 4

I claim: The combination with the straightedge of a card, of a rearwardly inclined index tab comprising a strip of transparent sheetcelluloid doubled upon itself, the two leaves of tne doubled strip tending to spring toward each other, the interior of the doubled. strip adjacent its foldforming with the strai ht edge of the card an unobstructed pocket or an index slip disposed wholly beyond the edge of the card, and an attaching strip cemented to the inner surface of the free margin of each of the two leaves of the doubled strip, said attaching strips being in turn ce-- mented to opposite sides of the card adjacent its said strai ht edge, both leaves of the doubled strip being similarly bent in a rearward direction along lines extending widthwise of the tab, the bends being substantially in register with said straight edge of the card and the. bend of the front leaf engaging said straight edge of the card and acting as a stop to determine the position of the tab with relation to said straight edge.

Signed by me :at Boston, Mass, this 29th day of April, 1921.
