Myinvention relatesto oice equipmen-t and more particularly to revolving card files and posting..tab1es.

The object of my invention is to provide a revolyfing. card le, which can be operated with very little effort.

i Another object of my invention is to provide a revolving card file which is in balance at all times.

A further object of my invention is to provide a revolving card file enabling the operator to post any card in the fue without having to change his position.

Astill further object of my invention is to provide a revolving card le enabling a second person to lhave access to the cards in the les from three sides of thetable, with which the file is connected, without interfering with the work of the file operator.

Other-objects of my invention may appear in the following specification describing my invention with reference to the accompanying drawings illustrating a preferred embodiment of my invention.l

Itis, however, to be understood that my invention is not to be limited or restricted to the exact construction and combination of parts described in' the specification and shown in the drawings but that such changes and modifications can be made, which fall within the scope of the claims appended hereto. In the drawings Fig. l is a top plan view of a posting table equipped with a revolving le according to my invention, the seat for a le operator being indicated in broken lines.

Fig. 2 is a front elevation of a posting table equipped with a revolving file forming the subjectmatter of my invention.

Fig. 3 isa top plan view of the frame work of the revolving disk in the posting table, the cover for the hub and center portion of this frame work being shown in section, and

Fig. 4 is a sectional view taken on line 4--4 inFig. 3.

Referring now in detail to the drawings, a posting table Il)l is provided in its top I I adjacent one of its ends with a circular cut-out I2.

Asupport member I 3 is fastened in any preferredconventional manner to the frame of the posting table I and extends diametrically underneath the circular cut-out I2.

An axle I4 has on its lower end a small circumferential flange I5 and underneath this flange aloa'sey iiange I6, which is bolted tothe support:

member i3 so that the axle I4 extends upwardly, ccncentrically with .the circular cut-out I2.

A hollow cylindrical steel hub Il hasa thrust ball bearingV I8 in each of its ends and is mounted rotatably on the axle Ill.

Four angle irons or arms I9 are rigidly connected with the hub Il, preferably bywelding, so that they extend radially therefrom at right angles'to. each other. The length of these angle irons I9 is such that'they will not reach entirely to the edge ofthe circular cut-out I2 in the table top I I, when they are attached to the hub I'l` and the hub is in position on the axle I4. The four angle irons I9 are arranged on the hub Il, so that one o2. the legs of each'angle iron extends horizontally and the other one downwardly and that the upper surfaces of the horizontally positioned legs .are located. in the same plane as the lower surface of the table top II.

Another set of fourangle irons 2li is firmly connected to the first mentioned angle irons I9 by being welded on top of these angle irons, so that the anglel irons 20 form a square, and the angle irons I@ extend diagonally to this square, as clearly shown in Fig. 3. The` upwardly extending legsof the angle irons 20 are located on 'the outside edge of the square.

A second square is formed by four shorter angle irons 2l, which are also welded onto the horizontally arranged legs of the diagonal angle irons I9,lso that the shorter angle irons 2| extend parallel 'to the langle irons 20 forming the outer square and that the upwardly extending legs of these shorter angle irons 2l are located at the inner edge of the inner square. The horizontally arranged legs of each pair of angles extending parallel to each other are' adapted to support a drawer 22 of a filing cabinet as indicated in broken lines in Fig. 4.

Onto the under side of each parallel pair of angle irons 2U and 2I an angle iron 23 is welded so that the downwardly extending leg of each of these four angles extends radially to the hub I1 and at right angles to the two angle irons to which it isattached. The inner end of each angle iron 23 is arranged flush with vertical leg of the adja cent shorter angle iron 2I and the outer end of said iron is located approximately at the same distance from the axis of the hubk Il as the outer end of thediagonal angle ironsl I9.

The portions of the horizontally arranged legs of the angle irons I9 and 23a, which extend beyond the outer square angle irons 20 support sections 24,01 plywood or otherl suitable material, abutting.

the upwardly extending legs of the outer square angle irons 20 and snugly tting onto each other. On the outer edge each section 24 is arcuate so that the four sections together have a circular shape of a somewhat smaller radius than the circular cutout l2. The upper surface of the turn-table formed by these sectors 24 is located in the same plane as the upper surface of the table -top Il. The latter and the turn table is preferably covered with a layer of Masonite or the like.

The plywood sectors 24 are fastened onto the horizontally arranged legs of the diagonal angle irons i9 and of the radial angleirons 23 respectively by fiat head screws 25 or the like.

To reinforce the hub l1 four braces 26 are formed by angle irons extending upwardly and inwardly from the back of the inner square angles 2l to the hub Il as shown in Fig. 4.

A square box-shaped cover 2l rests on the inner square and protects the hub and center portion of the turn table frame.

The above description shows clearly that the revolving card file according to my invention will be in balance at all times and can be rotated with very little eifort since the entire construction is supported by two thrust ball bearings. The turn table accommodates four drawers of a filing case, and each card in any one of these four cases is easily accessible by the operator, without forcing him to change his position,

It is, furthermore, to be understood, that a second tum-table of the same construction can be installed on the posting table, if so desired, to double the capacity of said table.
