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.
