Abstract
Abstract A continuous casting device comprising a rotating mold having a plurality of cavities on its outer surface into which molten metal is poured. As the device rotates, the metal solidifies and properly sized products in the shape of the cavities are drawn out of the cavities by the force of gravity as the cavities are rotated to an inverted position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
173 words
A continuous casting apparatus comprising in combination: a. a cylindrical base member; b. a sleeve member removably secured about the outer surface of said base member and contiguous therewith, said sleeve member having a plurality of cavities in its outer surface; c. sleeve cooling means comprising a plurality of channels disposed in said sleeve member with each channel coupled at one end to an intake coolant supply and at the opposite end to an exhaust coolant supply and having means for forcing said coolant from said intake supply through said channels into said exhaust supply; d. means for continuously rotating said base member and said sleeve member, said means comprising a drive shaft affixed to substantially the center portion of said cylindrical base member and motor means for rotating said drive shaft; e. means for pouring a molten metal into the cavities as they are rotated whereupon during rotation said metal in said cavities solidifies and the solid metal is caused to fall from said cavities when rotated to a substantially inverted position.
Claim 2
Dependent Claim
173 words
A continuous casting apparatus comprising in combination: a. a cylindrical base member; b. a sleeve member removably secured about the outer surface of said base member and contiguous therewith, said sleeve member having a plurality of cavities in its outer surface; c. sleeve cooling means comprising a plurality of channels disposed in said sleeve member with each channel coupled at one end to an intake coolant supply and at the opposite end to an exhaust coolant supply and having means for forcing said coolant from said intake supply through said channels into said exhaust supply; d. means for continuously rotating said base member and said sleeve member, said means comprising a drive shaft affixed to substantially the center portion of said cylindrical base member and motor means for rotating said drive shaft; e. means for pouring a molten metal into the cavities as they are rotated whereupon during rotation said metal in said cavities solidifies and the solid metal is caused to fall from said cavities when rotated to a substantially inverted position.
Claim 3
Dependent Claim
76 words
The apparatus of claim 1 wherein a cover is positioned over and spaced apart from said sleeve member so as to enclose said sleeve member while providing a space between the outer surface of said sleeve member and the inner surface of said cover, said cover having at least one opening for passing said molten metal into said cavities and means for introducing a non-reactive gas into the space between said sleeve member and said cover.
Claim 4
Dependent Claim
74 words
The apparatus of claim 2 wherein a plurality of nozzles are secured to said cover with the exit openings thereof positioned adjacent to and directed at the outer surface of said sleeve member, said nozzles being connected to a fluid coolant supply whereupon during the operation of said apparatus, said fluid coolant is caused to be sprayed through said nozzles onto said metal filled cavities in said sleeve member for quickly cooling said metal.
