Description
The objects of Lang's invention "are to provide such a construction of frame, made in sections, that as many sections as may be desired to accommodate a given number of files may be readily employed and secured together at will; to provide means by which the file will be suspended in juxtaposition with its appropriate cell in the most convenient position for inspection and handling of the papers; to provide a suspended index-clip, which, while it indicates that its file is out of the cell, contains a brief summary of the file contents, and upon which papers taken from the file may be charged; and to these ends the invention consists in the mechanisms fully illustrated in the accompanying drawings..."
