Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
In a mold for continuous casting, which mold includes opposed pairs of side and end plates forming an enclosure, said end plates lying between said side plates with their edges abutting the inside faces of said side plates, a one-piece liner of metal of high thermal conductivity within said enclosure, fastening means extending through said plates into said liner, and means within said plates for water cooling said liner, said liner having open ends to enable molten metal to be poured into the top and to discharge continuously from the bottom as a partially solidified casting, the combination therewith of improved means connecting said side and end plates to enable said mold to accommodate a four-piece liner interchangeably with said onepiece liner, said connecting means comprising bolts removably extending through one side plate, an end plate and into the other side plate, and combined conduit and spacer members positioned between and abutting the inside faces of said side plates outside said end plates, the conduits of said members being connected to the water-cooling means in said end plates, the spacers of said members being adjustable to accommodate liners of different width.

Claim 3
Dependent Claim
42 words
A mold as defined in claim 1 in which said water-cooling means includes vertically extending water channels on the inner faces of said plates, said plates having inlets to said channels near their bottom edges and outlets therefrom near their upper edges.
Claim 4
Dependent Claim
36 words
A mold as defined in claim 2 in which said side plates have openings near the top and bottom at each end, said conduits connecting the inlets and outlets of said end plates with said openings.
Claim 5
Dependent Claim
79 words
A mold as defined in claim 2 in which said side plates have openings near the top and bottom at each end, said mold including four of said combined conduit and spacer members providing conduits connecting the inlets and outlets of said end plates with said openings, flanges for attaching the members to said side and end plates and spacer blocks having tapped openings, and spacer bolts threadedly engaged with said tapped openings and abutting the opposite side plate.
Claim 6
Dependent Claim
34 words
A mold as defined in claim 1 including in addition adjustment plates carried by the edges of said side plates, and set bolts threadedly engaged with said adjustment plates and bearing against said liner.
