The invention is "particularly applicable, though by no means limited, to index demg the cards in the front elevation vices of that kind in which an upright frame supports a-series of cards, card hold- I I ers' or other movable index elements in overlappin spaced relation with their margins. exposed to display indexing or other char acteristics or inscriptions. v

For purposes of illustration the invention is herein shown as embodied in an index of well-known" construction consisting of a .frame comprising the back late 1 and the forwardly and inwardly irec-ted lateral flanges 2, 3, which as usual are integral with I the plate 1. A series of movable index elements 4, preferably made of aper or cardboard, and hereinafter re erred to as cards, are arranged in overlapping, spaced relation between the flanges 2, 3 of the frame and are so retained in position as to permit them to swing forwardly and -upwardly about their upper edges to'expose the data. inscribed upon them. method of holding the cards in th'ejframe is toattach' each card along its 11 per edge to a bar 5 made of Bristol boar or other suitable material whose opposite ends project beyond the sides of the card and en-' 'gagethe respective flan es 2, 3, thus holdrame. and defining pivotal axes about. which the respective cards may beswung.

Preferably. he lower edge of each card luloid or other transparent and resilient material doubledor folded to receive the lower edge of the card between its folds. -As herein shown the sheath is retained in position One convenient is protected by a sheath 6 made of'sheet oel- Y upon "the card by means of wire staples or clips 7, 8 arranged near opposite ends of the sheath and passing through both of its folds and through the card, a third 'staple 9 being provided if desired, intermediate the ends of the sheath, the latter staple passing through the card andthe rear fold only of the, sheath. it 3 A removable insert card 11 is slipped into the sheath 6 and is retained therein by engagement of its upper corners with'slits 11* inthe card 4. This insert card 11 covers the major part of the card 1 which in this case, with the sheath, serves merely as-a holder or movable support for-the insert card upon which the entry will ordinarily be made, although if desired, entries may be made directl upon the card 1, omitting the insert car 11. Tile identifying in provides a flaring entrance to facilitate slipping the insert card into the sheath, but also hasa desirable cooperative relationship to certain signal devices hereinafter more fully described. For the latter purpose it is preferred slightly to space the extreme marginal portion 13 of the rolled edge from the inner face of the front fold of the sheath, as indicated at 14, the rolled edge thus constituting a substantially tubular structure.

extending along the edge of the sheath and having a slit in its under side. This thickened tubular edge preferably stops short of the ends of the sheath in order to permit theend portionsof the front fold ofthe latter to be secured directly against the front face of the card 4, thus limiting lateral movement of the insert card.

The signal devices employed are in general of the same character and for the same purpose and function as those described in my prior Patent No. 1,317,643, September 30, 1919, but whereas in the patented arrangement the signal devices are illustrated as interlocking with the lower edge of the L insert card they are designed in accordance with the present invention to interlock or engage w1th the rolled-over edge of the sheath. As shown for example in Figs. 7

and 8 the signal device comprises a piece 15 of thin sheet celluloid,.vBristol board or other suitable resilient material which may be of any desired color, contour or other differentiating visual appearance, having its upper edge bent forwardly to provide a combined handle and supporting flange 15 and having one or more forwardly projecting tabs or tonguesformed by slitting the material at a point or points below theflange 15 and bending a portion of the material adjacent to the slit out of its normal plane. As shown in Figs. 7 and 8 the piece 15 is provided with a downwardly and' in-' I, wardly extending slit 16 at its opposite edges and the material at the lower edge of each slit is bent forwardly to provide a tab 17 whosev free extremity is directed upwardly toward the flange 15. When the signal device thus constructed is slipped into the sheath 6, the tab or tabs snap beneath the free lower margin 13 of the rolled edge 12 and into the space 14 while theflange 15 engages the upper portion of the rolled edge so that the signal device is securely'retained in operative position from which, however, it may be removed if desired, by springingthe forward fold of the sheath outwardly and lifting up on the flange 15.

In Figs. 9 and 10 the signal device 150 is shown as provided with a centrally disposed tab 18 of substantially rectangular outline integrally united at its lower edge with the main body of the material of which the device is formed and having its upper edge deflected out of its normal plane for interlocking engagement with the rolled edge of the sheath in the same manner as in the preceding form. In Fig. 11 a centrally disposed tab of substantially triangular form is shown at 19 as projecting from the body of the signallin device 20.

Referring to igs. 12, 13 and 14 a somewhat different form of signal device is shown, consisting of a piece of celluloid or other similar resilient sheet material folded upon itself to provide the forward leaf 21 and the rear leaf 22. The forward leaf 21 is rearwardly deflected at its free extremity toward the rearj leaf so as to provide a restricted entrance passage 23 leading to the space within the fold. This device is snapped over the rolled edge of the sheath the material of which the signal device is formed serving to retain it in position. This device may be removed when desired by springing the forward leaf 21 outwardly, whereupon the device may be lifted from off the rolled edge of the sheath.

In Fig; 6 the sheath is illustrated as integral with the movable index element 4, the latter in this case being made of'sheet celluloid which is bent at its lower edge to form the upwardly extending forward fold 6 which terminates at its upper edge in an inwardly and downwardly rolled margin 12 cooperating with the signal devices in the same manner as previously described While in most instances an insert card such as 11 will be employed with the movable. index device 4 or 4, it is manifest that the signal device and that portion of the movable index device or card which cooperates therewith function in substantially the same manner whether such insert card be employed or not. It is also clear that the retaining elements of the signal device are independent of its contour or other dis' tongue or tab, as well as the flanged portion of the signal device may be formed as a separatepart secured to the main body of the device, and it is likewise possible to form the retaining element of the sheath, consisting as herein shown of the inwardly and downwardly rolled edge, from other material and as a separate member suitably secured to the sheath.

I claim:

1. An index device comprisin a sheath for the reception of a card said s eath having a thickened edge portion, and a signal device extending into the sheath and havin a retaining element engagin said thickened edge portion to prevent accidental displacement of the signal device.

2. An index device comprisin a sheath for the reception of a card, said s eath having an inwardly turned edge, and a signal device extending into the sheath and having a projecting element en aging said edge to prevent accidental withgrawal of the signal device from the sheath.

3. An index device com rising a sheath having front and rear fol s the free edge of the front fold being turned inwardly and downwardly, and a signal device extending between the folds of the sheath and having a projecting tab interlocking with the downwardlv turned edge of the sheath.

4. An index device comprising a sheath having front and rear folds, the free edge of the front fold being rolled inwardly to provide .a downwardly directed margin 7 spaced from the inner surface of the front fold, and a signal device extending between ing upwardly into the space between the inner surface of the front fold. and the margin of the rolled edge of the latter.

5. A signal device for use with indexes of the class described comprising'a piece of thin resilient sheet material havmg slits extending inwardly from its opposite edges, the material at the lower edges of the slits being deflected out of its normal plane to form divergin retaining tabs.

7 6. A signal vice for use in card indexes of the class described comprising a piece of thin sheet material bent at one margin .to provide an outstanding flange, and a tab struck from the body of the iece and having its free extremity direct substantially toward the flange.

7. An index device comprisin a sheath for the reception of a card, said s ath having an elongate, signal-retaining element, and a signal evice extending into the sheath and having struck-up members normally disposed upon opposite sidesof said retaining element to prevent accidental displacementof the signal device.

8. An index device comprisin a sheath for the reception of a card, said s eath having a free edge portion, and a signal device consisting of a lpiece of thin sheet material extending into e sheath and havinga forwardly directed flange resting upon the free edge portion of the sheath.
