Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
148 words
A metal mold combination for use in the substantially horizontal casting of molten metal into a body comprising a plurality of corresponding upper and lower mold sections, first means for securing said upper sections together to form an upper mold assembly, second means for securing said lower sections together to form a lower mold assembly, said upper and lower assemblies together forming a mold having a cavity corresponding to the length of said body being cast, means for clamping said mold together, a substantially vertical pouring head, a pouring hole formed in the top of said head, means for attaching said pouring head to one end of said mold, closure plate means and means for attaching said plate means to the other end of said mold, whereby said mold may be provided in any selected length that is a function of the length of the individual mold sections.
Claim 2
Dependent Claim
148 words
A metal mold combination for use in the substantially horizontal casting of molten metal into a body comprising a plurality of corresponding upper and lower mold sections, first means for securing said upper sections together to form an upper mold assembly, second means for securing said lower sections together to form a lower mold assembly, said upper and lower assemblies together forming a mold having a cavity corresponding to the length of said body being cast, means for clamping said mold together, a substantially vertical pouring head, a pouring hole formed in the top of said head, means for attaching said pouring head to one end of said mold, closure plate means and means for attaching said plate means to the other end of said mold, whereby said mold may be provided in any selected length that is a function of the length of the individual mold sections.
Claim 3
Dependent Claim
41 words
The mold as claimed in claim 1 wherein said attaching means for said plate means includes fasteners connected to both said upper and lower assemblies of said mold, whereby said plate means assists in clamping said upper and lower assemblies together.
Claim 4
Dependent Claim
41 words
The mold as claimed in claim 1 wherein said attaching means for said pouring head includes fasteners connected to both said upper and lower assemblies of said mold, whereby said pouring head assists in clamping said upper and lower assemblies together.
Claim 5
Dependent Claim
48 words
The mold as claimed in claim 1 wherein is provided a plug positioned in said cavity in blocking relationship thereto at an intermediate point along one of said sections, whereby said body may be cast in lengths not a function of the length of the individual mold sections.
Claim 6
Dependent Claim
51 words
The mold as claimed in claim 1 wherein is provided a blowhole in the upper mold section adjacent said pouring head and a core in said blowhole permeable to gas, but sufficiently impervious to resist the flow of molten metal therethrough whereby gas may escape from said cavity but not metal.
Claim 7
Dependent Claim
24 words
The mold as claimed in claim 1 wherein said first and second securing means are operative to maintain said assemblies rigid to facilitate handling.
Claim 8
Dependent Claim
47 words
The mold as claimed in claim 6 wherein said sections are provided with flanges extending in a plane perpendicular to the horizontal axis thereof, said first and second securing means including fasteners engaging said flanges and maintaining the same in face-to-face contact to maintain said assemblies rigid.
