NEW JERSEY INDEX-CARD TAB Application filed March 12 1927. Serial No. 174,833.

without mutilating or cutting the edges of the card, and which can also be slid along the card to any desired indexing position without injuring the edges of the card. II

Provision is also madeforia comparatively tight grip of the device'with the card, but not suflicient to prevent the device from being slid into the desired position along the card.

The edge-engaging members are preferably formedas pointers, to cooperate with indices along one or both opposite margins of a card.

I Other details of construction will be hereinafter referred to. I I y I Referring to the'drawings, in which like parts are similarly designated 5 Figure 1 illustrates one form of our invention in elevation, asapplied to a card. Fig. 2 is a modification thereof. 1 Fig. 3 is a modification of Fig. 2. I Fig. 4' shows a tab having its lower hook substantially rectangular.

Fig. 5 illustrates a substantially rectangular upper hook. I V

Fig. 6 is a vertical central section of Fig. 5.

Fig. 7 shows a tab having asubstantially rectangular upper end.

Fig. 8 shows a blank.

Fig. 9 shows a tab madefrom such blank. I

Fig. 10 is a side elevation of Fig. 9. Fig. 11 is a side view, and; Fig. 12 a front view of a simple device similar to Fig. 2, made of wire. I I II F igsL'13 and 14 are side and front view s of another wire form having a tab or handle extension above the card. I V i I Figs. 15 and 16 are front and side views of another wire form. I I- I The tabs illustratedfor an index card may be made of thin sheet celluloid, thin sheet brass, wire, or other materiahand in each of the formsiillustra-ted comprises a narrow,

thin body portion having its lower end bent in the form of a hook, 16, and at or near its upper end a hook 17. These, hooks engage the straight, parallel unmutilatedjedgesof an index card 0, and are caused to frictionally grip the cardadjacent ways. I I k I I "'The tab can be freelyslid along the card its edges in various least one of the hooks on a tab is preferably formed as an index pointer 18, to cooperate with marginal subdivisions'on the card, for example subdivisions on'a scale 19, shown may be that such scale or subdivisions are placed near" the upper edge of the card,v or near both edges, according to the requirements of the'usen; I 1

In Fig. 1 the tab is shown as a'narrow thin metal strip having its lower endpointed at 18, and turned over upon itself to form a hook 16. The upper 'end'is similarly formed into any desired indexing position, and at near the lower edge of the card C, Fig. 1. It

pointed at 18, and turned upon itself to form V l the hook 17. In this figure the upper hook 17 is indented at 20 to form a slight protuberance on the under, side of'the hook to engage the card, and this protuberance lies opposite a cut-outportion or hole 21 on the back of the tab. sothat the protuberance will I I slightly flex the card. into the hole 21 to tightlylhold the tab in position, butnot so tightly as to prevent its being slid along the edges of the card.

16 and 17 may be provided with the'indentation 20, as in Fig. 2.

The-tabs of these {two forms havenoprojection above the'upper edge of the card upon which to place or write an indexing character, name, abbreviation, or the like,

andin order to provide this feature for our The hole 21 may be omitted, or both hooks I tabs we have designed the remainingIforms illustrated. I I a In Fig, 3 the tab extension'22 is narrow,

is in one piece with-the upper-hook and stamped from body portion 15, leaving the hole 23 with which the depression in the hook co-operates, as with the hole 21 in Fig. 1.

In Fig. 4 the at teaser; 22 i formd by the extension of the narrow body portion 15, and is the full width of said body portion. The upper hook 17 is narrow and stamped out from the body, as shown, leaving an opening behind from which it was cut, the protuberance 20 co-operating with the opening, as in Figs. 1 and 3. The lower hook 16 is substantially rectangular and has a cut-out portion 24 with which co-operates a protuberance 20 inthis instance formed in the body portion 15.

In Fig. 5 the protuberance 120 co-operates with a spring tongue 25 cut from the body 15 of the tab. At the upper end the tab extension 22 is cut from the hook 17 leaving an opening or window 124-, similar to the one 24 in Fig. 4, and with this opening cooperates a spring tongue 26.

In Fig. 7 the tab extension 22 is the full width of the tab, and a narrow hook 17 is cut therefrom, co-operating with a protuberance 27 on the body portion of the tab.

Figures 8 and 9 show a tab having an extension 22 wider than the body portion; the

' upper, wider end of the blank is provided with a window 28 and is bent over on the line 29, and the upper hook 17 provided with the protuberance is cut from the wider portion of the blank, andwhen bent to form, is as shown in Figures 9 and 10.

A small card or sheet of paper can be slipped under the extension 22 and the writing or printing thereon exposed through the window. The lower edge of this small card rests on the bend of the upper hook, which in conjunction with the spring action in the overturned window portion secures the small card in. place, and the card can readily be slid from under the window portion for replacement by another.

In place of flat strips, wire may be used, as shown in Figs. 11 and 12, where 15 is the shaft or body portion, having the hooks 16 and 17 at each end.

In Figs. 13 and 14: the wire is bent as shown to form an extension 22 above the card, for ready manipulation, while in Figs. 15 and 16 the body or shaft is formed of two wire portions 15 kinked at 20 and 20 to form theequivalent of the protuberance 20 in the other forms. The lower hook 18 is formed by the middle portion of the length of wire. At the upper end the wires 15 are bent over and downwardly at 30, then have short portions 31 extending toward the middle, the portions 32 rising vertically above the card edge, each of which is bent downwardly at 33, and the four portions 32 and 33 lie in a plane and are preferably soldered together.

A label can be slipped between the extension wires 32 and .the wires30 forming the hook;

In all the formsshown the index card is slightly flexed until its upper and lower dges pass between the books on the opposite comprising a long, narrow strip of material having hooks thereon for engaging over the opposite straight parallel edges of the card, and slidable along said card to any position along said edges, at least one of said hooks formed as a pointer for cooperation with a scale on the margin of the card proximate to said hook.
