Specification of Letters Patent.

0. Renewed January 6, 1918. Serial No. 740,546.

Patented Feb. 18,1913.

To all whom it may concern: v I

Beit known that I, CLAUDE B. S'riLnwnLL, a citizen of the United States, residing in Savannah, Georgia, have invented certain Improvements in Index-Cards for Filing Systems, of which the following is a specification.

The object of my invention is 'to so construct a card or other object (hereinafter,

for convenience, referred to simply as a card) that an index tab integral with the card can be located at any desired point in the length of the card, as may be required by the location of the card in respect to others in a filing system. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in whichigure 1 is a view of a card prepared for indexing in accordance with my invention; Fig. 2 is a similar view, with a selected in dex tab projecting from the card; Fig. 3 is a view of the card having the index tabs so arranged that any one of the same is available for use at any time; Fig.4 is a view similar to Fig. 3 but illustrating a selected index tab projecting from the card, and Figs. 5 and 6 are perspective views, on an enlarged scale, showing oppositesides of the card at'the point where the index tab projects therefrom.

In carrying out my invention I form at I that edge of the card I where tlie index tab ing shown in the is to be located, a series of incisions 2 extending inward from the edge of the card to the extent that the index'tab is to pro ect therefrom, thus forming at the edge of the card a series of index tabs 3 integral with the-body of the card, whereby any one of these tabs may be employed as may be required by the relation ofthe card'to others with which it may be grouped, the other tabs being removed, as shown in Fig. 2.

In order to stiffen and strengthen the projecting tab a suitable clip engaging the base of the tab and the adjoining ortion of the card may be used, one form 0 such clip bedrawing, and consisting of a strip of sheet metal or other available material folded around the base portion of the tab, as shown at 4 in- Fig. 5, the clip having projecting webs 5, 5, extending inwardly from the tab and lying on opposite sides of the card, these webs being confined together by means of a spur or barb .6 formed on the web 5, this spilir or. barb being passed through the material of the card andthen bent so as to overlap. the inner ortion of the opposite webs 5, as shown in ig. 5.

In some cases it may be advisable to change an indexing card from one positionto another, and in such case I prefer to so construct the card that any one of the index tabs 3 thereon can be used at any tinie. In order to effect this purpose I fold the entire series of tabs 3 inwardly over the body of the card, as shown in Fig. 3, and retain their inner ends by means of a pasted strip 7, preferably of thin paper or other material, which can be readily torn away from the inner end of the selected tab, thus permitting the latter to be folded outward into operative position, as shown in Fig. 4. If it is afterward desired to cliange the position of the tab on the card, the tab previously in use can be folded in over the card again and retained in the folded position by pasting a strip of thin paper over its inner end, or not,

as may be desired, the retaining-strip 7 bein then torn away from the inner end of a di ferently located tab and the latter folded out for use in the same manner as the first.

The card 1 may, if desired, be a strip of a width but little greater than sufiicient to form the tabs, this strip being secured in any desired manner to the card or other object which is to be indexed.

I claim:

1. An index card having, at one' edge, a. series of incisions forming a. succession or row of index tabs which are folded inward over the body of thecard, and a covering strip whereby the inner ends of the tabs are temporarily retained in the folded position.

2. An index card havin at one ed e, a projecting tab integral wit the body 0 the card, in combination with a clip for stiffening and strengthening the base of the tab and retaining it in the projected osition, said clip comprising a portion folded around the base of the tab, and. a member projecting inwardly ove'r the body of the card and secured thereto.

3. An index card having, at one edge, a projecting tab integral with the body of the card, in combination with a clip for stiffening and strengthening the base of the tab and retaining it in the projected position,

said clip embracing the base of the tab and having webs extending inwardly over the body of the card on each side of the same.

4. An index card having, at one edge, a

projecting tab integral with the body of the and bent so as to overlap the inner portion card, in combination with a clip for stifienof the other Web.

ing and strengthening the base of the tab In testimony whereof, I have signed my and retaining it in the projected position, name to this specification, in the nresence of said clip elgibracingdthe' base of the tab and two subscribing Witnesses.

havin We s exten in inwardly over the a body gr the Card on ea eh side of the latter, CLAUDE L E and. confined together and to the card by a I spur 0r barb formed on one of the Webs, 10 passing through the material of the card,
