Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
163 words
An open top high volume railway car body including a pair of side walls and interconnecting end walls defining vertically extending corner portions, a car underframe connected to a lower portion of said body including center bearing assemblies adapted to support said underframe on longitudinally spaced car trucks, said underframe including a center sill and longtiduinally spaced transversely extending horizontal support means supported on said bearing assemblies, the intersection of said center sill and said horizontal support means defining minimum vertical flexure portions a V-shaped truss including a pair of elongated braces bisecting respective corner portions and lying in a plane inclined relative to the end wall in upwardly converging relation thereto lengthwise of the car, said braces including upper end sections connected to respective corner portions and lower end sections terminating in the apex of said truss adjacent a respective minimum flexure portion, and lower coupling means rigidly interconnecting said lower end sections and securing them to the underframe of the car.
Claim 2
Dependent Claim
163 words
An open top high volume railway car body including a pair of side walls and interconnecting end walls defining vertically extending corner portions, a car underframe connected to a lower portion of said body including center bearing assemblies adapted to support said underframe on longitudinally spaced car trucks, said underframe including a center sill and longtiduinally spaced transversely extending horizontal support means supported on said bearing assemblies, the intersection of said center sill and said horizontal support means defining minimum vertical flexure portions a V-shaped truss including a pair of elongated braces bisecting respective corner portions and lying in a plane inclined relative to the end wall in upwardly converging relation thereto lengthwise of the car, said braces including upper end sections connected to respective corner portions and lower end sections terminating in the apex of said truss adjacent a respective minimum flexure portion, and lower coupling means rigidly interconnecting said lower end sections and securing them to the underframe of the car.
Claim 3
Dependent Claim
17 words
The invention according to claim 1, and said horizontal support means having a laterally extending bolster beam.
Claim 4
Dependent Claim
18 words
The invention according to claim 1, and said horizontal support means having longitudinally spaced longitudinally extending stub sills.
Claim 5
Dependent Claim
22 words
The invention according to claim 1, and said horizontal support means including a floor having a depressed center portion intermediate the trucks.
Claim 6
Dependent Claim
27 words
The invention according to claim 1, and said braces each being a rigid elongated tension and compression member resisting inward and outward deflection of said car walls.
Claim 7
Dependent Claim
38 words
The invention according to claim 5, and said braces having a longitudinal axis substantially coaxial with the resultant force of lateral and longitudinal car wall corner deflection forces, thereby essentially eliminating shearing and bending loads in said braces.
Claim 8
Dependent Claim
30 words
The invention according to claim 1, and upwardly diagonally extending bracing means parallel to said end walls and spaced therebetween rigidly coupling said side walls and said horizontal support means.
