  • FIGS. 4C and 5 are side elevations of the' lower and upper flasks, respectively;
  • Fig. 6 isa perspective 7 shows a series of drag molds with precast links in position, and
  • Fig. 8 is a plan of the completed and connected molds apertured to sand molds.
  • My invention relates to the making of cast steel chain links in the form of a continuous chain, and consists in casting the chain without the use of inserted cores or mold parts in My invention also consists in the various steps which I shall hereinafter describe and claim.
  • the pieces 5, 5' which, with the piece 6, comprise the form of half of a link.
  • the pieces 3 and 4 are slightly larger than the shape of a link and serve to form impressions in the mold in which the reformed links are to be set.
  • the piece 6 lias a central depending stub portionfi, intended to form the impression for the stud portion of a link.
  • this snap flask Upon the board 2 is also a snap flask 7, which extends from the board up to the line indicated by A in Fig. 2. As is shown in Fig. 1, this snap flask consists of four sides hinged at M and latched at-N, so that when the latch N is released the .fiask may be swung open and removed'from about the mold. When the flask'is in position upon the board, sand s Specification of Lettert ratent.
  • Patented Jan. is, 1921.
  • Sections of chain may be connected by placing the end links of sections in. a single mold and pouring a connecting link therebetween.
  • the whole chain may be cast at one time, as is shown in Fig. 8, through the gates 10 and 10 but as ithas been found that more uniform results have been secured by pouring all of the links arranged in one plane, it is preferred to first cast the separatelinks on a vertical or a horizontal axis and then to complete the chain by later pouring the connecting links, also arranged on a similar axis, as has been described above.
  • a pair of flasks arranged oneabove the other, part patterns for three links being secured in the under flask, the part pattern for one link being arranged in a plane at right angles to the plane of the patterns for the other two links and projecting above the top surface of the under flask, the second flask being removable with its upper part mold to permit the withdrawal of the part of the pattern projecting above the top surface of the under flask after the forming of the lower part mold in the under flask, the remainder of the part patterns being withdrawn from the bottom of the lower part mold.
