Abstract
383,027. Card indexes. LORENTZ, R., 38, Kaiserdamm, Charlottenburg, Berlin. Oct. 20, 1931, No. 29130. Convention date, Oct. 25, 1930. [Class 16.] In a card index in which all the cards are of the same size and shape, a stepped visible index reading both in horizontal rows and vertical columns is provided by cutting away portions of the cards adjacent to one of the upper edge preferably in the vicinity of one or both corners. According to the arrangement shown, wherein each horizontal row shows three items, the 4th, 7th, 10th, &c. cards have rectangular strips cut away from the corners increasing in depth by an amount equal to the depth of the visible space on each card, and the intermediate cards have cut-away parts of corresponding depth to the succeeding card of the series referred to above but varying in width to form the intermediate subdivisions.
