INDEX-TAB.

Original application filed May 14, 1917, Serial No. 168,447.-

.Specification of Letters Patent.

1917. Serial No. 178,830.

To all whom it may concern:

Be it known that I, GEORGE J. .AIGNER, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Index-Tabs, ofwhich the following is a specification, reference being had to the accompanying drawings, illustrating same.

My invention relates to indexes, for use in connection with books, various kinds of letter and card files, loose leaf arrangements, etc. It may, however, be used in various places and adapted for various conditions.

This application is-a division of my copending United States patent application Serial N 0. 168,447, filed May 14, 1917, on index tabs. One object of my present invention is to provide improved index tabs as herein set forth.

Another obj eet of my present invention is to provide improved strips of index tabs. as herein set forth,.constructed so'that the single or individual tabs of the strip may be readily and quickly detached therefrom for use.

Other objects will be apparent from the following specification. In the accompanying drawings illustrating some of the preferredforms of my invention, Figure 1 is a side elevation of a strip of index tabs of the invention, with portions cut away to show the interior construction of the strip; Fig.2 is a top. end view of the strip of tabs of Fig. 1; Fig. 3 is a side elevation of'a single tab taken from a strip of tabs similar to the strip shownin Fig. 1; Fig. 4 is a side elevation of a strip of another form of index tabs of this invention, with portions cutaway to showthe interior construction of the strip Fig. 5 is a top end view of the strip of tabs of Fig. 4,

showing the attachable ends of the tabs spread apart for moistening, to condition them to be glued to their proper sheets for use; and Fig. 6 is a side elevation of a single tab taken from a strip of tabs similar to the strip shown in Fig. 4.

Like characters refer to like partsin the several figures.

Index tabs in strip form have generally been made with the series of tabs in the form of a continuous strip having no incisions between the various characters on the strip to enable the individa ul tabs to be readily detached from the strip for use. In

their other forms of tabs the individual tabs of a set are cut entirely apart from each other and placed loosely in a box. In the former class of, tabs tabs from the strip for use, entirely across the strip, but in such a strip of tabs the cutting cannot be uniformly done by hand so that the individual tabs after being cut apart will have a uniform appearance, width, etc.; and in the latter class of tabs it is necessary to sort out the individual tabs of a set of different characters and arrange them in their proper order before gluing them to respective sheets for use, which consumes considerable time and is a great bother.

In my present invention I have devised an improved tab and strip of tabs which eliminate all of the objectionable features above mentioned. I accomplish this result by cutting the individualtabs n, B, C, D, E, etc, of a strip of tabs, nearl T apart from each other, as shown by lines 1 1 which re resent cuts inthe strips of tabs, but still leave the individual tabs of a strip all connected together by narrow attachment portions 2 2, preferably as shown. These attachment portions 2 2, in the forms of my invention illustrated in the accompanying drawings, are at the extreme front edge of the strip. With this construction the attachment portions in the folded edge of the strip and in a portion of the filler hold the strip of tabs stiffer and straighter than where the attachments are at other portions of the strip, due to the stiffness of the filler and the folded edge portion. With the attachments at the front folded edge of the strip it is easier to clip the individual tabs apart, because it is easier to clip one portion than two portions which are separated from each other as in the opposite legs of the tabs, especially with tabs having angularly projecting legs as illustrated in Fig.4. It is hard to clip the last-mentioned tabs ap t if the -ttachment portions 2 2 are medially disposed in the strip between the attachment legsof the tabs. Clipping the tabs apart gives smoother, more uniform and better appearing edges than twisting the tabs apart.

lVith the cuts 1 1 between the individual tabs of a strip, providing the small attach ments 2 2 between the tabs, the tabs of a set or series are kept in their proper order, thus eliminating the objectionable feature of having to sort them out where they are cut clear it is necessary to cut the individual apart from each other as above stated. My improved tabs may, however, be readily and quickly separated from each other for use,

preferably by clipping the small attach strip as in'the tabs above mentioned, which cutting cannot be done by hand so that the severed tabs have a uniform width and appearance.

In all of the tabs illustrated, each tab comprises. an. outside portion 3, which may be of leather, celluloid, paper, canvas, cloth, etc, and the innerportion. or tiller 4 for stiffening the front portion of the tab, the outside portion 3 being folded over around the inside portion 1, preferably as shown in Figs. 2 and 5, and being suitably glued or cemented thereto so that the portions 2, 4i, 3 constitute a solid body portion. The filler 1ispreferably cemented in placein the long folded portion 3 in the form of a long strip, before. the cuts 1 1 between theindividual tabs are made. The filler 4; may be of paper, canvas, leather, cloth, or any other suitable material, and 1 preferably make the filler 1 the same color as the outside: portion 3: of the t: bs, so as to present a better appearance along-the top and bottom edges of the tabs.

The inner surfaces of the. attachable legs 6 6 of the tabs, back of the filler strip 4, are preferably gummed, so that they may be moistened and glued to their proper sheets very readily. In moistening the surfaces 5 5 of the tabs, the legs 6 6. thereoi may bespread apart as shown'in Fig. 5 and pressed, orrubbedagainst any suitable moist sponge or other object.

The attachment portions 2 2 between the individual tabs of a strip arepreferably locatedas shown in the drawings, so that each attachment comprises part of the folded portion 3 and filler 4:. l

Each of the individual tabs shown in Fig. 4t is constructed as shown in Fig. 6, that is, with one of the attachable legs 6 extending upwardly from the body portion of tlie'tab and the other attachable leg 6' extending downwardly from the body portion ofthe tab, preferably as shown. This construction is provided so as to reinforce the sheet to'which; the tab is attached for use, adjacent to the tab, and thusprevcnt the sheet from tearing in case the tab is twisted or roughly This conof the sheets and tabs. I wish it to be understood that I may vary the shape of thelegs 6 6 oftlietab. of Fig. 6 as desired.

In certaimformsof my tabs 1 may do away with the filler 4 and glue the portions 3 3101 the fold directly to 'each' other, thus providing-a stiff solid portion for the front portion of the tabs. V

The characters on a set of tabs may be the. letters of the. alphabet, the numerals,

the daysof the month, abbreviations for the months, abbreviations for States, names of individuals, companies,- etc., or, in'fact', anything desired. V r

I do not wish to limit'this invention to all of the particular details herein set fortlnas various modifications thereof may be made or utilizedwithout departing from the scope of the appended claims The broad ldea of connecting the individual tabs of a strlpnby small scverable attachments, is claimed in United States Reissue oPatent No. 1 1,550, on index tabs, reissued Nov. 19, 1918. p I. hat I: claim as my inventlon is 1. A seriesof index tabs arranged in'the form of a. strip according toa predetermined zontal body portion composed of a folded portion, andattaehment legs for each of the tabsprojecting.angularly from the rear end of the horizontal body portion, one upwardly and one downwardly whenth'e tab is attached to a vertically-disposed sheet, the consecutive tabs of the stripbeing connected together only by narrow severable attach: ments at theextreme frontedge of the strip holding the tabs in their predetermined arrangement'in the strip but'permitting of them being readily detached-from each other foruse. v I

2. A set of index tabs of the character set forth comprising a series of tabs normally in a strip and provided with different characters thereon arranged consecutively according to a predetermined arrangement, the said strip comprising a folded portion having a front portion for the characters and a rear portion for providing attachment legs for the individual tabs, the said tabs being cut entirely apart through the-said rear portion and through the said front portion to within a short distance from the front edge of the strip whereby narrow severable attachments between the individual tabs are provided at the'front edge only of the strip, the said attachmentsv holding the said tabs in their predetermined arrangementin the strip but permitting of them being readily detached from each other for use.
