Abstract
Abstract A ladle car having a body rotatable about a horizontal axis has an opening at its top with a main spout casting on each circumferential side thereof. A removable spout is attached to each main spout casting by means of bolts passing through aligned holes in two sets of matching lugs, one lug of each set being part of the main spout casting and the other being part of the spout. The spout includes a central generally U-shaped refractory lined spout portion having a downwardly extending convex bottom wall and two side walls. The spout portion extends beyond the ladle body and the main spout casting, but not to such an extent that it will prevent rotation of the body through 360*.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
In a ladle car including a generally cylindrical body for containing molten metal or the like, means mounting said body on said car for rotation about a generally horizontal axis to effect rotation and discharging of molten metal from said body, and at least one spout support on said body having a pair of spaced apart generally circumferential lugs extending outwardly therefrom; the improvement comprising a slot in said spout support between said lugs, a removable spout member secured to said spout support between said lugs, said spout member including a central generally U-shaped spout portion having one end received in said slot and the other end forming a lip extending outwardly and spaced beyond the periphery of said body whereby molten metal discharged from said body is diverted from the periphery of said body, an outwardly extending flange at each side of said spout member one adjacent each of said lugs and means connecting each flange to said U-shaped spout member, and means securing each flange to the adjacent lug.
Claim 2
Dependent Claim
171 words
In a ladle car including a generally cylindrical body for containing molten metal or the like, means mounting said body on said car for rotation about a generally horizontal axis to effect rotation and discharging of molten metal from said body, and at least one spout support on said body having a pair of spaced apart generally circumferential lugs extending outwardly therefrom; the improvement comprising a slot in said spout support between said lugs, a removable spout member secured to said spout support between said lugs, said spout member including a central generally U-shaped spout portion having one end received in said slot and the other end forming a lip extending outwardly and spaced beyond the periphery of said body whereby molten metal discharged from said body is diverted from the periphery of said body, an outwardly extending flange at each side of said spout member one adjacent each of said lugs and means connecting each flange to said U-shaped spout member, and means securing each flange to the adjacent lug.
Claim 3
Dependent Claim
51 words
A ladle car according to claim 1 in which said U-shaped portion has a convex downwardly and outwardly extending base, two side walls, a flange extending upwardly from the discharge end of said base between said side walls, and a refractory lining on the inside of said base and side walls.
Claim 4
Dependent Claim
28 words
A ladle car according to claim 1 including a pair of lifting lugs extending outwardly from said spout member one between each flange and said U-shaped spout portion.
Claim 5
Dependent Claim
51 words
A ladle car according to claim 3 in which said U-shaped portion has a convex downwardly and outwardly extending base, two side walls, a flange extending upwardly from the discharge end of said base between said side walls, and a refractory lining on the inside of said base and side walls.
Claim 6
Dependent Claim
27 words
A ladle car according to claim 4 in which the top of said spout support and the top of said spout member are at the same level.
Claim 7
Dependent Claim
33 words
A ladle car according to claim 1 in which the projection of said U-shaped spout portion is such as to permit rotation of said body through 360* without contacting the car supporting surface.
Claim 8
Dependent Claim
51 words
A ladle car according to claim 6 in which said U-shaped portion has a convex downwardly and outwardly extending base, two side walls, a flange extending upwardly from the discharge end of said base between said side walls, and a refractory lining in the inside of said base and side walls.
Claim 9
Dependent Claim
28 words
A ladle car according to claim 7 including a pair of lifting lugs extending outwardly from said spout member one between each flange and said U-shaped spout portion.
Claim 10
Dependent Claim
27 words
A ladle car according to claim 8 in which the top of said spout support and the top of said spout member are at the same level.
