METHOD MAKING: MOLIDS.
l lhddll'dil.
.To all whom may concern:
Be it known that we, Davin Ens'rntiln, litoenes and Conn M, li liion'nnn, citizens of United fdtates residing at Severance, in the county of Franklin, State or" Tennessee have invented certain new and method for making molds for castings which will enable such molds to be made and a casting of any size, weight or degree of complexity to be formed, without moving the mold or heating same by means of a furnace. In order that our improved method may be clearly understood reference will be had to the accompanying drawings wherein- Figure 1 is a top view of a form employed in eflecting the first step of the improved method; Flg. 2, a top view of the form with the core filling therein and showing the heat conveying elements, this view being completely illustrative of the first step of the improved method; Fig. 3, a view illustrative of the second step of the improved method; Fig. l, a view illustrative of the third step of the improved method; and Fig. 5, a view illustrative of the fourth and dast step of the improved method.
in carrying out our improved method we first produce a form of the desired shape and of suitable material such as wood, plaster, cement or metal. This form is indicated at 10. We then placeconveniently within Specification of.I.etters Patent. P t t d gimme an 91 Application filed may 1, 1916. serial No. 94316.
of the form. We then till the form 10 with a materlal having a low melting point such as one of the fusible alloys, sulfur or paraffin, such material being indicated at 19 The form 10 is then removed from the resultant core and the latter is then surrounded by a suitable mold forming material 13, such as sand. The heat conducting element 11 is then rendered active to melt out the core 12 which leaves the finished mold as illustrated in Fig. 5, it being understood that the heat conveying element 11 is removed after the core 12 is melted out. When these steps are completed the mold is ready to receive the desired casting.
What is claimed is 1. The herein described method of making molds for castings consisting of forming a core of material having a low melting point and with a heating element embedded therein, surrounding the core with a suitable mold forming material, then rendering the heating element active to melt the core, and
the form 10 a heat conveying element 11 such as single or double tubes, flexible or rigid for the conveyance of steam or other heat medium or we may employ any other suitable heating device within the form or some other method of heating the interior then removing the heating element from the mold forming material.
2. The herein described method of making molds for castings consisting in filling asuitable form having a heat conveying ole-- ment therein with a material having a low meltin point to form a core having an embedde moving the form from the 001e,.surrounding the core with a suitable mold forming material, then rendering the heat conveying element active to melt the core, and then removing the heating element from the mold forming material.
In testimony whereof, we afix our signatures in the presence of two witnesses.
