Definitions

  • My invention relates to a method and the means for making double-sided molds in a single flask. It is an object of my invention to improve the casting conditions of such 6 molds and to this end I arrange the patterns in staggered relation so that the impressions in the finished molds are also staggered, and the molds on being superimposed will form a sort of step, the gate of each mold being exposed separately, as distinguished from the normal arrangement, in which the gates in the several molds are aligned vertically, forming a gate extending throughout the pile of molds.
  • the patterns in the pattern plates were arranged in line, that is, in exact vertical relation to each other. Molds made in this manner can be superimposed only vertically and with a gate extending vertically throughout the pile of molds, runners connecting the gate with the cavities of the several molds. As the metal is poured into the top mold, the ladle is disposed high above the lower molds in the pile so that the g metal enterswith considerable impetus and the molds, particularly the lower ones, are
