Application filed February 1.6, 1922. Serial No. 537,018.

Be it known that we, ll-Liaoiin Mery systems.

" primary Object of the invention is to provide a strong and durable tab construc-U tion which will more readily withstand the bending stresses usually placed' upon the tab in fingering overthe guidey cards to locate the desired section or sub-division. As the index tab projects above the upper edge of the card while the card itself is more or ,less firmly anchored between the contentsv of the filing drawer, the tab forms a cantilever, and if not substantially con-l structed and designed, breaks or cracks yat the fulcruming point where all of the strain. is focused. j

Accordingly, the present invention contemplates a novel tab having a compartinent for receiving the label, the walls of said compartment being transparent andv provided with an opening 'for inserting and removing the label, the .said opening being arranged and disposed in such a way that the structure of the tab is in no way weakened in the Zone where the bending or leverage strains are concentrated.

A further and more specific object of the invention is to provide a simple, sanitary, fand practical construction that may be easily and economically manufactured..

With the above and other objects in view which will more readilyappear as the nature of the. invention is better understood, the same consists in the novel construction, combination, and arrangement of parts, i hereinafter more fully described, illustrated and claimed.

A preferred andv practical embodiment 'of' lthe upper edge o Figure 3 is a vertical sectional View taken on the line 3 3 OfFigure 1I 'f f Figure t'is -a horizontal `sectional lview taken on the line 4r-l of- Figure 1.v

Figure 5 is'fa rear eleva-tion `of a guide i card showing a modified type Oft-ab construction providing two access openings for the labelcompartinent. Y

corresponding parts throughout the several figures of the drawings.

Similar reference characters designate.

y e5 According `tothe present invention, it is proposed topi'ovide the guide card l with an integral tab `projection 2 projecting above y y i of the guide'card'a suitable distanceto enable the tab -tO-be readily sighted `and distinguished when the guide card is` inposition in the filing drawer. The tab projectionv'lQris preferably cut away or punched out, asy indicatedfatt, thereby `providing anfopen'ing 'whose )lo'wtgry edge extends well into the body of the; guide card so `ras to carry the relatively rweakest point of the tab to a' point below the upper edge thereof and enable thematerial ofthe card "to better resist the bendingl strain which is concentrated more orv lessat this otherwise weak vpoint of the tab.

The recessfor openingl, asfwellas the opposite faces of the tab, are vcoveredwby an enveloping sheet 5 of transparent mate`-r rial, preferably celluloid, the same being foldedover the edge of the vtab so as to present .a continuous and vsmooth protecte the saine frombecoming soiled or curled up by lingering and also prevent the Celluloid from being separated from the kbody of the tab. In other words, the Celluloid sheet 5 is foldedupon itself and placed astride the tab sothat itsfolded edge is located' atthe top of the tab while the Opposite ywings thereofprovide transparent walls w and w yfor the recess 4L thereby providing a lcompartment for receiving and holding a labelr L bearing the necessary indicia for identifying ythe contents of the file drawer. y

By reason ofthe fact that ythe recess 4 extends above and below the upper edge 3 of the card body 1, a label within the compartment may contain upper and lower lines of indexing matter such for example asarelatively large general index letter which` may be on the upper half'of the label and always ing edge 6 for the top of the tab to prevent exposed to view While the portion of the label below the lupper edge of the card may contain further and more explicit data as to the contents of the particular subdivision.

As previously indicatedthe novel and distinctive feature of the present invention is to provide a tab construction which is reinforced lWhere the bending pressure is usually centered and to thatend the access.

` is required to be cut away or removed. While at the same time the full reinforcing` effect imparted to the material ofthe tablby the not disturbed.

Celluloid Wings w and w of the sheath 5 is Therefore, the tab remains fully reinforced by the stiffness of the protecting sheathy or cover, enabling it to successfully withstand bending strains which would otherwise be focused at the horizontal or longer edge of the recess l and in the rela-tively small Web portions 2a of the tab. y l

l/Vhile vit Will of course be understood that the distinguishing characteristic of thcpresent improvement resides in the particular disposition ofthe access slot or opening 7, it Will of course be understood that the invention is not limited to the use of asingle opening adjacent one of the vertical edges of the recess of the tab, but `as shown in Figure 5 the rear Wing of the transparent reinforcing sheath 5 may be provided WithV those skilled in the art and it will of course be understood that changes in the form, pro-v l portion and minor detailsl of construction may be resorted to Without departing from the spirit of the invention or scope of the appended claim,

Vile claim A. tab for guide cars including a card body having a tabextension providedyvith a recess lying Within the extension and also extending into the card body, a sheath of transparent material folded to vembrace the tab kprojection so that the Wings. thereof cover opposite sides of the recess to provide a labelreceiving compartment, and a vertical slot in one of the wings of the sheathr located ad-` jacent one of the vertical edges of the recess; ln testimony ,whereof We hereunto aiz: oui-'signatures in the presence of two Witnesses.
