The present invention relates to vertical iiling systems.

Vertical ling systems are known in which small l separator strips project beyond the recording cards and form a means for finding any selected recording card. The recording or index cards are arranged between the individual separator strips.

The usual filing systems have separator st'rips allowing an oblique survey, said strips being narrower than the recording or index cards and provided at the bottom with teeth engaging corresponding spacing members. This arrangement has the disadvantage that the separator strips, consisting of resistant material, are rather thick and must be relatively broad particularly if aV safe mounting is to be obtained. Now, if the oscillating axis of these separator strips is placed at .the upper edge of the teeth so that the foot ends freely oscillate, the foot ends require a considerable additional oscillating space. If, however, the oscillating axis is placed exactly at the bottom end of the separator strips, this additional space March 7, 1940, Serial No. 322,713 Germany December 9, 1938 (ci. 12e-fie) l viscose or cellulose acetate are most suitable also must be provided, because during oscillation the recording or index cards in this case have aV diii'erent angular position than the one of the separator strips the axis of which is arranged in a low position. Neglecting the requirement of the oscillating space has the eect lation .the parts of the piled and rigid teeth at the ioot portion are pressed against each other and that completegroups of index cards-.are lifted ofi the bottom.

Numerous prior art drawbacks are obviated by the present invention by the fact Athat the separator strips consisting of very thin and very exible material engage at least over two spacing members and that the foot ends, overlapping each that during oscilother in the center of the length, easily bend e against each other when they are oscillated. The y spacing members have a circular cross section which facilitates their production as Well as the exchange ability of the separator strips. The flexibility of the ends of the separator strips obtained by the provision of a short slot in thel center of the ends of the separator strips easily allows the arrangement of the oscillating axis exactly in the height of the upper edge of the spacing members, provided a Very small play of bending is present in the circular recess. As the separator strips are always very long with regard to their ioot end, the bending pressureof the two foot portions overlapping each other is very small during oscillation. `As strip material-.thin and very the advantage is obtained Jiiling satchel, or the index which with regard tothin metal have the ad vantage that .they slide far more easily upon paper and do not rust. The easy exchangeability is obtained by providing the foot ends of the separator strips with at least two circular or slightly oval perforations respectively which terminate in a slot tapering downwardly.

The bottom of the box of the ling system may be provided with notches or rails the, cross-section of the upper portions of which is\circular. `The best way, of course, is to provide unobstructed rods, because .the recessesof the separator strips may be very small only for the' purpose o f ensuring good stability of the individual separator strips. The safety projection provided at the lower side of the oval recess, therefore, is only strong enough if this recess completely embraces the profile. A

These unobstructed relatively thin rods must be provided with numerous cross supports. It is, thereforaadvantageousto arrange the rods in ling boxes which have a small width relatively to the depth of the box.

that a large group of index cards may as a ywhole be taken ofi.' the box and dealt with at any desired place. The individual tiling boxes or satchels are technical units' independent of each other and' may be placed in any desired container which is indispensable i'or the unlimited use of the ling system. The ling boxes may also be broader than the index cards so that a plurality of groups of index cards may be arranged side by side inthe cards may laterally be oiset betwe/en the separator strips if they are provided with teeth at their ,lower edge.

Anothergvery important advantage is obtained according to the invention by the fact that the separator strips consist of transparent material.'

When using separator'strips of opaque material the survey of the index marks is prevented over the total ling system.

This ldrawback is obviated by the fact that the rator strips is tapered or rounded so that they may be differentiated from each other. The

separator strips now form short and resistant tabs to which refer indicating marks. The indiiiexible transparent artificial materials based on cating marks are arranged at the upper edges of the card group separators guided in transparent cross. members mounted'lbetween the individual groups of separator strips. when using numbers Hereby simultaneously of the guides carrying said transparent cross members and adapted to be xed to the card group separators a permanentsurvey of all rows of numbers may simultaneously be obtained. In connection with names arranged upon oblique plates the separator strips always are arranged in front of the plates having the corresponding name. To obtain survey of a group of cards, the card group separator first of all is turned.

It is well known to write indications or markings upon the individual separator strips or to provide same with a system of rules or with exchangeable small plates referring to tabs. 'I'he complete eifect of exchangeable plates carrying namesv only then facilitates the use of the filing systemif the plates also may be displaced in an oblique position and if no separating line exists between the plates and the tabs. ,These difIlculties often occurring with prior devices are obviated by the fact that the guide for the plates entirely consists terials based on viscose orcellulose acetate which is so arranged that simultaneously the entire upper edge of the card group separator is protected/against damages. The walls of the guide for the card group separators are bent to admit to easily exchange the small plates and to obtain a spring action towards the wall of the card group separator.

The slight thickening of the upper edge of the card group separator, however, has also the effect that climbing of groups of cards is absolutely prevented.

In the accompanying drawings the invention is shown by way of example.

In these drawings:

the

and A Fig. 8 is a perspective view of a support of the filing device of Fig. 'I fixed to the edge of a table.

The collecting device I consists of stiff cardboard similar to the cover of a book and is p rovided at lwith a hinge, whereas back 3 is rigidly connected to side walls l by frame 5 serving to support the spacers. Frame 5 may consist of two simple iron rails provided with rows of perforations carrying rods. A more suitable construction, however, is shown in the drawings. The frame here consists of a rust proof sheet metal covering the entire back and having both sides bent upwardly. The side walls extend obliquely from the top towards the lower part and are each provided with a row of perforations. The perforations carry circular rails or rods I some of which are passed through cover I of the ling device and fixed. by nuts or rivets. The metallic lining of the back of of transparent synthetic ma` Fig. '7 is a perspective view of a nling device the filing device enhances as reference marks requiring a small height only` easy sliding of the metallic feet 6 and I0 of the card group separator II and protects the back against bending. Finally the metal back may be pressed from 'a rectangular sheet metal with a small consumption of material and thus has a small weight only. The sides of the card group separator II are provided with sheet metal reinforcings the extensions of which serve as feet land are clamped together below the cardboard.

The feet have such a length that the lower side of the cardboard portion of card group separator II occupies a position some centimeters above the spacing members.

The upper edge of the card group separator II is surrounded by a folded strip I2 of transparent synthetic materials based on viscose or cellulose acetate the front portion of which contains a plate section provided with symbols. The plate may be pushed under the left and right hand sides of the metal edges and may be exchangeably fixed in this manner or may be connected to the card group separator II by an ear extending through the longer rear portion.

Fig. 2 illustrates two separator strips Il and I5 to explain the oscillating or turning operation. 'I'he foot ends of the separator strips I4, I5 are provided with the above described recesses and overlap each other in the middle of their length. For the purpose of increasing the bending capacity the foot end is provided with a short slot I6 arranged about in its middle portion. The punched out portions of slot I6 preferably extend radially outwards to facilitate insertion of the separator strips.

Fig. lishows a construction which differs from the JuSt described construction by the fact that the card group separator is provided with strips I! consisting of atransparent synthetic material based on viscose or cellulose acetatel which allow the provision of exchangeable plates I8 carrying names arranged in an oblique position. The strip I! surrounds the entire upper edge of the card group separator and the lower bent portion 20 extends through a slot 2l in the card group separator. After the Celluloid strip I9 has been inserted the rear side of the slot 2l is to be covered by a strip of material fixed by an adhesive. Due to its stretching ability easy application of the strip of transparent artificial material based on viscose or cellulose acetate is `provided in such a manner that said strip is safely fixed without using any auxiliary means. The groove of the rail I9 contains a fixed support 22 consisting of a colored material and a movable support consisting of a transparent synthetic material based on viscose or cellulose acetate which allow the arrangement and guidance of plates I8 in an inclined position. Thenames are applied by a typewriter onto the originally continuous plates.

The advantages of ling systems using separator strips are well known. With the construction according to the present invention special index or guide tabs are nearly superfluous as a complete sub-division is obtained already by means of the separator strips. -The economy of space is considerably increased by the employment of the flexible overlapping separator strips and their easy oscillation renders the operation of this filing system rather agreeable and free of objections. The construction is very simple and cheap.

The filing device shown in Fig. 5 .consists of cardboard or other suitable material and is provided with walls A23 and 24 the upper portions of which are oscillatable, whereas the short lower portions are rigidly held in their position by the 2,297,442 `sheet metal insert 25. The sheet metal member 25 is xed fby pins 26 which extend through elevations of the insert .25 provided at the right and left hand side and in this manner connect the side walls 23, 2li. 'I'he wave-shaped elevation of the insert 25 arranged farthest to the right and to the left are provided with perforations 2l into which engages the hinged hook-shaped spacing Ipin 28 of the main card group separator 29.

The iiling device illustrated in Fig. 7 is provided with a` cover -which may be closed by buttons 30. The inserted separator strips and recording or index cards must exactly iill the interior height of the filing device. Then the latter may Ibe arranged in any position without the position of the recording cards being altered.

Fig. 8 illustrates a metal support which in the ordinary manner may be screwed to the edge of a table. This support may also be rotatable so that the operator may Ibring same in any desired position.

The invention allows the arrangement of large filing systems in classifiers and shelves which in.

many cases is necessary for reasons of lack of space. Moreover, the survey is facilitated and the costs of the entire arrangement are considerably reduced.
