in such manner that the printed matter is' always visible on the faces of. the cards, each of which is provided with some form of device adapted to engage and support the one ,aboveit.

I have simplified, reduced the cost, and improved the efficiency of the card-supporting device and have also improved the com struction of-the card-holding frame, as hereinafter described and illustrated in the accompanying drawings, in which- Figure -1 is a perspective view of the index composed of a series of cards and the frame in which they'are held and supported. Fig. 2 is a perspective view of the frame alone. Fig. 3 is ai'ear or back view of a portion or section of the index illustrating the arrangement of the card tongues, whereby each card is supported on another be.- low it. Fig; fl is a perspective view illustrating the manner of inserting a card in the frame. Fig. 5 is a perspective view lifting of a card in rear of one just inserted. Fig. 6 is a back view showing a card raised for readjustment after Fig. 7 1s a vertical adjusted and supthe frame.

The frame of my improved index has an oblong rectangular form and is distinguished by the utmost simplicity of construction, it being. composed of interiorly grooved side bars 1 and top and bottom cross bars 2 and 3, all formed of thin sheet metal 'such as tinned iron or aluminum. As shown in Figs. 1 and 2, the flat top cross-bar 2 is soldered or riveted to the one has been inserted. section of cards duly backs of the side bars 1, so thatt-he grooves ofthe latter are left open or free at the top to permit cards to be slid out of the frame. The bar 2 has a downwardly and rearwardly projecting flange 2 which serves as a guide for the cards in that it prevents the tongues of the latter catching on the rectangular form and bar when cards are slid out of the frame. The bottom cross-bar 3 has an angle form in cross section and is so applied to the ends of the side bars as to practically close the frame at that point, so that it forms a direct support for the bottom card of a series and thus indirectly for the whole series, while preventing their escape downward. By constructing the frame as described, it has due rigidity, also extreme lightness, and maybe manufactured at very small cost, while at the same time adapted to hold cards securely and permit their ready insertion and removal.

The cards, indicated by the numeral 4- Figs. 4 and 6'-have an oblong are provided with see especially tongues 5 which'are integral portions of the cards, the same being formed by an inverted U-shaped cut and by bending backward or outward'the tongues thus formed, so that they roject at a sharp angle and are thereby a apted'to engage the bottom of the card above and thus support the latter.

Fig. 1 shows a face view of the frame nearly filled with cards, and all of those above the bottom one supported on the latter. In other words, each card in the series above the bottom one is supported on the one 7 below it, its lower edge resting on the tongues 5 of the lowest or bottom card of the series. The arrangement of the cards with reference, to the supporting tongues is best illustrated in Figs. 3, 6 and 7.

Inorder to insert a card in the frame be- Patented Dec. 1'7, 1912:

tween any that may be already in it, one

hand suffices, and it is only necessary to bow the card slightly outward, as in Fig. 4, to permit insertion of its ends simultaneously or successively in the grooves of the side bars 1, and then, the card being released, it may be pushed into place, so that its lower edge rests on the pro ecting tongues 5 of the card below it. In such case, however, the inserted card lies directly in front of another,

and it is therefore necessary to raise the rear one and with it all that lie above and are supported upon its tongues. In this operation, as shown in Fig. 5, the card behind the newly inserted one 15 seized betweenthumb and finger and lifted to the position shown in Fig. 6, and in such case all the cards above it are necessarily raised also, slnce each rests on the tongues of the next card below it. Practically this operation is reversed for removal of a particular card. Thus, the card seized'andidrawn upward until its lower edge is above or of the card thatwas in out of and below it, and

to be removed is particular card which is being removed; then, upon bowing the latter, its ends are drawn bars 1, and its tongues are at the same time sprung outward sufficiently to free them from the bottom edge ofthe card abovel derordinary conditions they retain thevIn'the construction of the cards, they may be cutout of large-sheets by means of a. cutter also constructed to serve as adie in that it resses the tongues outward simultane- Sy with the cutting operation, so that'unspring or cantthus given and stand perma- =nently at the required acute angle. Thus by this construction, the cards themselves are provided with integral spring supports'for frame.

thus the entire f th '7 beallslid bodily out those above them in the I It will be seen that .while the angular flower cross-bar 3 supports the lower card'and series above it and prevents e escape of the cards at that point, the arrangement of the top bar 2 permits them to sired. It also permits the convenient inser- "tion of all or a series of cards, so that they course, raises also all the cards that 5. lie above the out of the grooves of the side of the frame when debe readily scribed. v i
