Patented Nov. 1 7, 1931 UNITED STATES cam. nrnnmzsmr, or sanrnanoisc camronnia susrnnsronnnvrcn Application fil ed September 29, 1930. Serial No. 435,040.;

My invention relates to animprovement in filing devices and more particularly to; ade:

tachable tab or device for supporting and fil:

ing away maps, charts, drawings, tracings, blue prints and in fact any sheet material 1n a convenient manner. f

An object of my invention is to provlde a new, novel and inexpensive removable tab for supporting sheet like materials upon a rod or like support.

' Another object of, my invention to provide in a tab of the above character a novel means for securing the tab to the art cle to be supported.

A further object of my invention is to pro: vide a new and improved feature in a tab of the above character which will facilitate the engaging of the tab with its support and otherwise render the tab more effective. 7

Other objects and advantages of my invention will be in part pointed out and 1n part evident to those skilled in the art from the following description and the. drawlng wherein I have shown by way of illustration and not of limitation a preferred embodiment of my device. r In the art to which my invention pertains there have been several attempts made to provide a simple supporting means of this character. One good example of a prior art device is illustrated and described in'Umted States Patent to Jesse W. Fontaine, lflumber 1,687,859. In this patent there is disclosed a celluloid member through which a rod opening is provided and over WhlCll a piece of adhesive tape is disposed so that the ends of the adhesive tape may be secured upon opposite sides of the supported article. This device has found some favor in the trade but 40 is open to the objection that when once applied to the article it cannot be removedand used a second time. I By my invention I provide a supporting tab which is of such construction that it can be used indefinitely. I11 addition to the above, my-improved tab also embodies features to be hereinafter pointed out in detail which render it easily attachable and removable from the supported article and the supporting rod by a convenient and simple operation and in such a manner that the article supported will not be subjected to any knife edge support, as is the case in a number of prior artdevices wherein the tongues are projectedthroughthe article in a vertical me. 1 Y

Fora better understanding of my, inventionreferenceshould be had to the accome panying drawings wherein like numerals res fer to like parts throughout the several vlews. a.

-.In the drawings r q Figure 1 is a perspective view showing a single sheet article suspended upon three parallel supporting'rods, I V

Figure 2 is a front elevation of the tab, and Figure 3 is a view similar to Figure 2 showing my improved tab provided with an adhesive sticker. i a Q In Figure 1 of the draWingsI show a single sheet of material suspended upon three parallel extending rods of a filing rack of the type disclosed in my copending application Serial No. 219,204, filed September 13, 1927. As here illustrated, the supported article designated by:the numeral 10 is provided along its upper edge with three of my improved suspension devices 11. The suspension devices or tabs 11 areshown as clipped over three parallel suspension rods 12. .The tabs 11 30 are here'shown as attached toa sticker 13 whic'h is applied directly to the surface of the article 10 by any suitable adhesive. In practice the tabs 11 will be mounted upon the article 10 in properly spaced relation so that when once applied they can be easily pulled from and replaced upon therods 12 in aconvenient manner. p

' A suspension tab which will give the greatest amount of filing capacity. must be very thin and therefore it is desirable that the tab be made of some strong material. A preferred material which possesses thisthinness withoutfa sacrifice. of strength or flexibility is spring steel. 7 While this material is ideally suited for this purpose it cannot be used, because of a tendency to cut its way through any material suspended thereupon, unless some special arrangement and form of attaching 1 means is provided.

their particular perforations as the tab is allower portion 14 is such that the tongue-s15" will be disposed in a line substantially radial As shown in Figure 2, I overcome the above difliculty by providing the lower portion of my tab with a plurality of tongues which are so arranged that the material suspended thereupon will not be subjected to a single straight line knife edge suspension. As shown in this ,figureof the. drawings the tab 11 is illustratedashavinga downward-1y ex;

tending inverted keystone or pyramidally shaped portion 14 upon each side of which there is provided threeou-twardly'projecting tongues 15. The slope of the sides of the with an aperture 16 in the upper portion and:theyaresospaced that their points ofen-v gagement with'the article tobe suspended-will lie 'inailineat an an'gle to the vertical and horizontal dimensions of the sheet .material.

h; In addition to the tongues 15 the lower portion 14 is shown as provided with a hole 17 through whichianordinary paper fastener may be inserted when it is desired to suspend additional sheets of-materlal on a single set (if-suspension tabs. The tab 11 is also pro vided with an upper portion in which there is formed the aperture 16 to which an incision ELS -cut in its upper edge extends. The aperture 16' and the incision '18, because of their arrangement, form-What might be termed two upwardlyfextending semicircular portion-s whichmeet at their upper ends and which-due to the flexibility ofthe material will always lie in substantially the same plane. At this point attention is also called to the fact that these upwardly extending curved portions are cut awayfas at 19, so as tof-a'cilitate their deflection'in passing them *overthe-suspension rods 12'. I 1 By providing several tongues on each'side 'ofthetabs as shown the tabs will'be held firmly and flat-upon the surface of the sus pended article, *and by shaping the bottom portionl l oif the tabs-asdescribed, in'the :form

of an inverted keystone or pyramid, it ispossi-bletosuspendheavier materials as the pull upon'each of the tongues 15 will be exerted al'ong-difi'erent vertical lines.

- A further advantages in forming the bottom portion of the'tab as shown is that when tothe"disposition trait tongues 15, and'when the tabs are to be applied to weaker mate rials, such as thin blue prints, I provide the tabs 11 with the stickers 13, as shown in Fig ure 3-01 the drawings, which as previously stated are adapted to be adhesively attached to the surface of the article. \Vith this latter arrangement .it will .beseenlthat the project g tonsu s -ii e comp ete y en between the stickers 13 and the article sheet IO aii dconsequently there will be no projectin tend's whiclrcan-damage adjacent similarly suspended sheets. Ifit is desired to suspend more than one sheetofmaterial froma single set of suspension"ta'bs this 'beconvenien'tly done by perforatingthe sheet 10 adjacent theholel? in' the tab llandlpassing a suitable paper fastenertherethrough. I v

In operationwhen my improved tabs have beena ifixedto a sheet of material the tabs can be conveniently placedovertherods.12 by placing the curved portions 19 centrally against the rod and applying it slight pressure. This will cause; the upper curved portions to flex in opposite directionsand spread the incision 18 sothat the rod will easily pass therethrough. When it is desired to removevthe sheet ifrom-therods 12 this can be done by merely pulling downwardlyon the sheet which-operation will cause the ;upf periportions to vagainflei: as when they were placed uponthe rods 12. f-In order to facilie tate this latter operation I I may, where the size of the tabsand the diameter or" the rods-12 warrant, slightly roundjoff the cornersat the ends of the incision 18 so that the steel or other stifl'material willhave no tendency .toiscratch or cut intothe rods 12. When the tabs .11 are provided with adhesive stickers,--'as illustrated in Figure 3,-they can be easily removed from the article-without removing-the stickers 13 and they can then be used again :by simplyadding asecondsticker toieach of the tabs.

-While I have for the sake of: clearnesszand .inorderto disclose myinvention so -.that-the same canebe readily understood, described and illustrated specificdevices, materials and arrangements, I desire tohave it understood that this invention is notlimited to the is? cific means disclosed but maybe embodied in other ways that willsuggest themselves, in view-10f this broad disclosure, to persons skilled in the art.- It is believed that this inventionis broadly.- new. audit is desired to claim it .assuch so that :all such changes as come wlthm the scope of theappended claims are to be consideredas part ofthis invention.
