Abstract
Abstract Disclosed herein is railway apparatus or the like for mixing and transporting molten metals, particularly pig iron, which essentially comprises a longitudinal, refractory lined cylindrical vessel, provided at its opposite ends with removable cover members and also provided with a self-contained drive unit for rotating the vessel about its longitudinal axis. This vessel, with its associated self-contained drive unit, is removably supported beneath its ends upon two spaced railroad trucks, through ball joints associated therewith. The vessel and drive unit may be readily separated from the underlying trucks for installation, maintenance, and/or removal of the refractory lining in any desired vessel orientation, while the vessel is rotated by its self-contained drive unit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
A mixer-transport apparatus for molten metals or the like comprising a. a longitudinal, cylindrical vessel having a refractory lining and removable end covers; b. bearing means journalling said vessel for rotation about the longitudinal axis thereof; c. support structure means connected to said bearing means for supporting said bearing means and said vessel; d. underlying wheeled truck means mounting said support structure means; e. joint means disposed between said truck means and said support structure means accommodating the separation of said support structure means from said underlying truck means; and f. self-contained drive unit means for rotating said vessel mounted on said support structure means and forming with said vessel, said bearing means and said support structure means, a single structural entity for separation as a whole from said underlying truck means.
Claim 2
Dependent Claim
132 words
A mixer-transport apparatus for molten metals or the like comprising a. a longitudinal, cylindrical vessel having a refractory lining and removable end covers; b. bearing means journalling said vessel for rotation about the longitudinal axis thereof; c. support structure means connected to said bearing means for supporting said bearing means and said vessel; d. underlying wheeled truck means mounting said support structure means; e. joint means disposed between said truck means and said support structure means accommodating the separation of said support structure means from said underlying truck means; and f. self-contained drive unit means for rotating said vessel mounted on said support structure means and forming with said vessel, said bearing means and said support structure means, a single structural entity for separation as a whole from said underlying truck means.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1, further characterized in that a. said support structure means includes strut means projecting outwardly from said vessel; b. said self-contained driving means are supported on said strut means.
Claim 4
Dependent Claim
23 words
The apparatus of claim 1, further characterized in that a. said self-contained driving unit means are disposed adjacent the ends of said vessel.
Claim 5
Dependent Claim
164 words
A mixer-transport apparatus for molten metals or the like, comprising a. a longitudinal, cylindrical vessel having a refractory lining and removable end covers; b. bearing means journalling said vessel for rotation about the longitudinal axis thereof; c. said bearing means including circular roller bearings with inner and outer races; d. support structure means for said bearing means and said vessel; e. said outer race affixed directly to said support structure means and said inner race affixed directly to said vessel; f. underlying wheeled truck means mounting said support structure means; g. joint means disposed intermediately of said truck means and said support structure means accommodating the selective separation of said support structure means from said underlying truck means; and h. self-contained drive unit means for rotating said vessel mounted on said support structure means, and forming with said vessel, said bearing means and said support structure means, a single structural entity which may be selectively separated as a whole from said underlying truck means.
Claim 6
Dependent Claim
164 words
A mixer-transport apparatus for molten metals or the like, comprising a. a longitudinal, cylindrical vessel having a refractory lining and removable end covers; b. bearing means journalling said vessel for rotation about the longitudinal axis thereof; c. said bearing means including circular roller bearings with inner and outer races; d. support structure means for said bearing means and said vessel; e. said outer race affixed directly to said support structure means and said inner race affixed directly to said vessel; f. underlying wheeled truck means mounting said support structure means; g. joint means disposed intermediately of said truck means and said support structure means accommodating the selective separation of said support structure means from said underlying truck means; and h. self-contained drive unit means for rotating said vessel mounted on said support structure means, and forming with said vessel, said bearing means and said support structure means, a single structural entity which may be selectively separated as a whole from said underlying truck means.
Claim 7
Dependent Claim
27 words
The apparatus of claim 4, further characterized in that a. the central lower portions of said outer race are in the form of a reinforced saddle segment.
Claim 8
Dependent Claim
46 words
The apparatus of claim 5, further characterized in that a. the lower surfaces of said saddle segment include socket means for engaging a ball means; b. said separable joint means is in the form of a ball joint, including said socket means and a ball means.
Claim 9
Dependent Claim
66 words
The apparatus of claim 5, further characterized in that a. said outer race includes upper plate-like elements which cooperate with said lower saddle segment to define a circular race; b. said inner race and said outer race cooperate to define an annular retainer; c. a plurality of roller elements disposed in said annular retainer end accommodate the smooth rotation of said vessel about its longitudinal axis.
Claim 10
Dependent Claim
58 words
The apparatus of claim 7, further characterized in that a. sprocket wheel means are affixed to the outer surface of said vessel; b. said self-contained driving unit includes a sprocket drive wheel means; c. an endless roller chain interconnects said sprocket wheel means for transmitting torque from said self-contained drive unit to said vessel to rotate the same.
