No. 16114.—18th March, 1903.—WALTER HENRY PEARSON, of Dunedin, New Zealand, Gentleman. Forming sheet metal into cubes.

Claims.—(1.) In the forming of cubes especially for the purposes set forth, a machine consisting of discs of two diameters placed alternately so as to form cutting-rolls, said discs the thickness of the required cubes and placed apart so that the discs are as far apart as the size of the required cubes, combined with combs to clear out the grooves between the discs and a guide for feeding squarely to the said cutting roller discs, all substantially as described and explained, and as illustrated in the drawing. (2.) In combination, in a machine for cutting sheet metal into strips and crosscutting said strips by same or a similar machine to cubes, cutting-rolls formed in the solid or built up of layers of large cutting-discs E and small bedding-discs E¹, having a thickness similar to the size of required cubes, with a feeding-table B and clearing-combs C, all substantially as described and explained, and as shown in the drawing.
