Abstract
The drum constitutes an independent unit comprising two horizontal sheet steel circular platforms which are concentric with the axis of the column and spaced vertically apart. The lower platform is of large diameter and supports by their lower edge the files whose vertical edge opposed to the back of the files bears against a peripheral flange on the upper platform. The two platforms are rigidly assembled by radial struts whose end portions are fixed to the respective platforms and constitute separating elements defining compartments in each of which compartments a group of files may be filed.

In a filing drum for a column having rotary drums, the drum comprising two coaxial vertically spaced horizontal platforms having a generally circular shape, radially extending obliquely disposed separating rods connected to the two platforms and defining compartments in the shape of sectors for receiving files, or like objects, which are disposed vertically and have a vertical edge which is capable of abutting the periphery of the upper platform which is of smaller diameter than the lower platform, and means for rotatably mounting the drum on the column;
- the improvement wherein the two platforms are of sheet metal, the upper platform comprises a peripheral flange which is press-formed on the upper platform and said separating rods constitute struts which have end portions and fixing means fix said end portions respectively to the lower platform and to said peripheral flange, which flange performs the function of an abutment for the files or like objects.
A column in combination with filing drums which are rotatably mounted on said column in superimposed relation, said column comprising tubular sections, screwed connection means which assemble said sections, a cross-shaped stand, a vertical sleeve which is fixed to a centre part of the stand, said vertical sleeve having an upper end portion, screwed connection means which assemble the upper end portion of said vertical sleeve with a lower end portion of a tubular section of said tubular sections which corresponds to the lowermost drum of said drums, which lowermost drum bears on said upper end portion of said vertical sleeve with interposition of a thrust bearing, each of said drums comprising two coaxial vertically spaced horizontal platforms having a generally circular shape, radially extending obliquely disposed separating rods connected to the two platforms defining compartments in the shape of sectors for receiving files, or like objects, which are disposed vertically and have a vertical edge which is capable of abutting the periphery of the upper platform which is of smaller diameter than the lower platform, and means for rotatably mounting the drum on the corresponding tubular section of said column, wherein the two platforms are of sheet metal, the upper platform comprises a peripheral flange which is press-formed on the upper platform, and said separating rods constitute struts which have end portions, and fixing means fix said end portions respectively to the lower platform and to said peripheral flange, which flange performs the function of an abutment for the files or like objects.
