The form shown in Figs. 5-7 of the group of cards distinguishes itself from that shown in Figs. 1-4 fundamentally only in that instead of using binders consisting of round string 6, 5 fiat bands In, H are employed, which consist preferably of thin sheet metal, for example, watch spring steel of similarstuff. The back end of each of the bands l I is preferably fixed in the form of a joint in the vertical direction on the lower end of the back cover plate 2 like a hinge. The front ends of the bands each terminate in an eye 12 and is secured by a piece'of wire l3, which, by means of two sheet metal hinges M on the upper end of the front cover plate 3, is fixed so that it can be drawn out.

Provided no alteration in the mutual position of the cards of the single groups, and therebyno alteration of the holes, is contemplated, the holes not required can be omitted, that is to say, on each card there will be only two border holes so positioned as to provide the required echelon of the free edges.

As in the case of the index cards, such as can be moved vertically, one can fashion each one of the cards as a pocket, open at the top, for insertion of the actual account sheets, and,-if pre-' ferred, one can use as a backing for such a pocket, a stout back sheet which, according to the simple sheets to be inserted, is punched and filed on the two bands Ill and l l with suitable holes and the upper edge of which, by virtue of the staggered holing, can be used for designating or labelling the accounts.

In the form shown in Figs. 8-12 of the invention, the arrangement is such that in this case the leaves formed as pockets to contain account sheets of each group of cards are closed in echelon.

form. For this purpose the backs of both covers I5 and I6 are lengthened by the sum of the amounts of echelon of each pocket at the upper border with respect to the filing bands I0-ll which are connected between the front cover l6 and rear cover 15, the cover being connected by means of 'a flexible strip I! of leather or suitable fabric.

The two elastic filing bands It, H are preferably of thin steel, each being terminated at the front with a button l8 sliding in a vertical slot' IQ of the front cover parallel to the plane of the appropriate filing holes of the cards or pockets. The length of the two filing bands is so'proportioned that two connected s pporting covers can two covers l5 and I 6, the two buttons I 8 of the filing bands l0 and H, rise in their slots. When these covers are closed the pliability of the bands permits them to bend easily and without permanent alteration of form, but bending does occur such that the cards or pockets, in taking up their normal echeloned position make only a slightrelative vertical displacement. By this is obtained a greater life of the pockets.

In use the visible groups of cards, the neces-'- sary number are preserved in open containers (boxes), the side walls 2| of which are arranged at a distance apart the width of the cards, while the front and back covers 22, 23 are hinged with hinges (24) at their lower ends and can be held in position by means of a pair of slot rings 25 attached to both sides. The files in the preservation box can he leaned in a slightly sloping position partly against the front, 22, and partly against the back cover 23, so that between these two groups there is room to open .the foremost file of both groups and render it accessible, as Figure 12 shows.
