  • Fig. 3 is a section on llnes III-III of Fig. 2
  • Fig. 4 is a vertical longitudinal section of the mold box and mold after the box has been lifted

  • Fig. 6 is a perspective view of a completed quarter mold
  • Fig. 7 is an elevation of a serles of quarter molds with preformed links in place
  • FIG. 8 is a top plan of a series of completed molds ready y invention relates to the making of cast steel chain links in the form of a continuous chain and consists in casting the chain in sand molds without the use of inserted cores or mold parts.
  • My invention also consists in the various steps which I shall hereinafter describe and claim.
  • the molds are formed in the mold box 2, which has a bottom or board 3 which may be integral therewith.
  • the attern 4 which corresponds to the form 0 one half a link A divided longitudinally.
  • Each piece 6 also is in the form of onefourth of the stud or intermediate connecting portion of the link pattern B.
  • the member 8 is intended to form a projection 10 on the end of the mold while 'the piece 9 forms a complemen tary recess 11 into which a corresponding Specification of Letters Patent.
  • each of the members 8 and 9 also has a recess 12 on its inner face which takes about a corresponding projec- 15101113 on the piece 6 and serves to hold such lece firmly in position in the mold box.
  • he end members 8 and 9 have on their outer faces sufiicient draft or taper to perm1t the easy removal of the box from the mold afterit has been inverted.
  • a completed quarter mold is shown havmg an impression 4 for a half longitudinal section of a link A, two impressions 5 for quarter sections of two complete link impressions B, and also impres- 510115 6' for quarter sections of the stud port1ons of the link impressions B.
  • a correspondingly shaped quarter mold may then be formed, which, when arran ed side by side with quarter mold just descri ed with the impressions 1 in registry, completes the form of one-half of a mold.
  • the quarter molds In order to maintain the quarter molds in alinement they may be provided with the projectlons 14 and recesses 15 in their meeting faces, which are formed by complementary depressions and projections on the bottom 3 of the box.
  • a pair of similarly formed quarter molds are then placed with their meeting faces on the vertical line of division between the pair of quarter molds first mentioned, thus forming a complete connectin link impression B.
  • a series of quarter molds are arranged end to end, as is shown in Fig. 7, and preformed links A are placed in the impressions 4'.
  • a series of complementary quarter molds are next placed with their impressions 4' facing the impressions 4' on brought into alinement, the meeting edges about the gates 7 are luted with a silicions material and the connecting link or links are then poured in the impressions B. The molds are then broken up and a connected section of linked chain is found to have been formed. It is obvious that as many links as are desired may be connected together by the method which I have described.
  • the whole chain may be cast at one time by pouring the impressions 4', as is shown at the right in Fig. 8, throu h the gates 7*, thereby forming the links 2' as well as the connectinglinks in the impressions'B in the same casting operation.
  • the herein described process of making continuous cast-chain which consists in forming at one ramming a mold section having in one face a half-link impression and quarter-link impressions contained within said mold section and opening into the said face and ends thereof, associating said mold section with complementary mold sections to 1m a complete mold and pouring the mol 2.
  • the herein described process of making continuous cast chain which consists in formin at one ramming a mold section containing in one face a half-link impression, and in forming by removable pattern pieces in a.
  • a box for forming cast chain link molds comprising sides and bottom, a pattern piece to form a part impression for a central link secured on said bottom and pattern pieces to form part impressions for adjacent links arranged in a plane at right angles to the plane of the first mentioned poured a continuous chain is propattern piece, each of said second mentioned pattern pieces being made in parts, said parts being separable and withdrawable from within the mold through aside and bottom thereof respectively.
  • a box for forming mold sections for east chain links comprising sides and a bottom, a pattern piece to form a part impression for a chain link, other pattern pieces to form a part impression for an adjacent link, said last named pattern pieces meeting at the point of change of radius of curvature of the second named link, and each of said last named pattern pieces being contained Within the body of the mold section and being removable along its own curved axisfrom Within the mold section.
