Abstract
Abstract A railway tank car including a longitudinally extending tubular body shell, first and second truck saddle structures respectively positioned adjacent to the outer ends of the body shell for supporting the same upon associated trucks each carrying draft connections, first and second elongated slabbing structures respectively positioned between the first and second truck saddle structures and the body shell, first and second reinforcing members respectively associated with the first and second slabbing structures, each of the reinforcing members including a plurality of parallel spaced-apart bars extending longitudinally of the body shell, the reinforcing members cooperating to provide at least one bar extending substantially the entire length of the body shell between the slabbing structures, the bars being suitably secured to the slabbing structures and to the body shell to distribute stress due to buff and draft forces to the body shell.

Claim 1
Independent Claim
213 words
A railway tank car comprising a longitudinally extending fluid-tight tubular body shell, first and second truck saddle structures respectively positioned adjacent to the outer ends of said body shell for supporting the same upon associated trucks each carrying draft connections, first and second elongated slabbing structures respectively positioned between said first and second truck saddle structures and said body shell and suitably secured thereto, each of said slabbing structures extending longitudinally of said body shell and conforming to the outer adjacent surface of said body shell, first and second reinforcing members respectively associated with said first and second slabbing structures, each of said reinforcing members including a plurality of parallel spaced-apart bars extending longitudinally of said body shell along the bottom thereof from a position disposed upon the inboard end of the adjacent slabbing structure to a position disposed toward the inboard end of the other slabbing structure, each of said bars being substantially rectangular in transverse cross section and being suitably secured to the adjacent slabbing structure and to said body shell, whereby stress due to buff and draft forces transmitted by the couplers and the associated draft connections to said elongated support structure is distributed to said body shell along the portion of said reinforcing members secured to said body shell.
Claim 2
Dependent Claim
213 words
A railway tank car comprising a longitudinally extending fluid-tight tubular body shell, first and second truck saddle structures respectively positioned adjacent to the outer ends of said body shell for supporting the same upon associated trucks each carrying draft connections, first and second elongated slabbing structures respectively positioned between said first and second truck saddle structures and said body shell and suitably secured thereto, each of said slabbing structures extending longitudinally of said body shell and conforming to the outer adjacent surface of said body shell, first and second reinforcing members respectively associated with said first and second slabbing structures, each of said reinforcing members including a plurality of parallel spaced-apart bars extending longitudinally of said body shell along the bottom thereof from a position disposed upon the inboard end of the adjacent slabbing structure to a position disposed toward the inboard end of the other slabbing structure, each of said bars being substantially rectangular in transverse cross section and being suitably secured to the adjacent slabbing structure and to said body shell, whereby stress due to buff and draft forces transmitted by the couplers and the associated draft connections to said elongated support structure is distributed to said body shell along the portion of said reinforcing members secured to said body shell.
Claim 3
Dependent Claim
39 words
The railway tank car set forth in claim 1, wherein each of said reinforcing members includes three parallel spaced-apart bars, the center ones of said bars extending substantially the entire length of said body shell between said slabbing structures.
Claim 4
Dependent Claim
38 words
The railway tank car set forth in claim 1, wherein each of said reinforcing members includes three parallel spaced-apart bars, the center one of said bars having a longitudinal extent larger than the other ones of said bars.
Claim 5
Dependent Claim
30 words
The railway tank car set forth in claim 1, wherein each of said reinforcing members includes three parallel spaced-apart bars, the outer two bars having essentially the same longitudinal extent.
Claim 6
Dependent Claim
56 words
The railway tank car set forth in claim 1, wherein each of said reinforcing members includes three parallel spaced-apart bars, the center one of said bars extending beyond the ends of the other ones of said bars, the other ones of said bars having essentially the same longitudinal extent and being aligned one with the other.
Claim 7
Dependent Claim
31 words
The railway tank car set forth in claim 1, wherein the portions of said bars near the inboard end of the adjacent slabbing structures are unsecured to the adjacent slabbing structure.
Claim 8
Dependent Claim
30 words
The railway tank car set forth in claim 1, wherein the portions of said bars near the inboard end of the adjacent slabbing structure are unsecured to the body shell.
Claim 9
Dependent Claim
202 words
A railway tank car comprising a longitudinally extending fluid-tight tubular body shell, first and second truck saddle structures respectively positioned adjacent to the outer ends of said body shell for supporting the same upon associated trucks each carrying draft connections, first and second elongated slabbing structures respectively positioned between said first and second truck saddle structures and said body shell and suitably secured thereto, each of said slabbing structures extending longitudinally of said body shell and conforming to the outer adjacent surface of said body shell, first and second reinforcing members respectively associated with said fIrst and second slabbing structures, each of said reinforcing members including three parallel spaced apart bars extending longitudinally of said body shell along the bottom thereof from a position disposed upon the inboard end of the adjacent slabbing structure to a position disposed toward the inboard end of the other slabbing structure, said bars being suitably secured to the adjacent slabbing structure and to said body shell, whereby stress due to buff and draft forces transmitted by the couplers and the associated draft connections to said elongated support structure is distributed to said body shell along the portion of said reinforcing members secured to said body shell.
Claim 10
Dependent Claim
202 words
A railway tank car comprising a longitudinally extending fluid-tight tubular body shell, first and second truck saddle structures respectively positioned adjacent to the outer ends of said body shell for supporting the same upon associated trucks each carrying draft connections, first and second elongated slabbing structures respectively positioned between said first and second truck saddle structures and said body shell and suitably secured thereto, each of said slabbing structures extending longitudinally of said body shell and conforming to the outer adjacent surface of said body shell, first and second reinforcing members respectively associated with said fIrst and second slabbing structures, each of said reinforcing members including three parallel spaced apart bars extending longitudinally of said body shell along the bottom thereof from a position disposed upon the inboard end of the adjacent slabbing structure to a position disposed toward the inboard end of the other slabbing structure, said bars being suitably secured to the adjacent slabbing structure and to said body shell, whereby stress due to buff and draft forces transmitted by the couplers and the associated draft connections to said elongated support structure is distributed to said body shell along the portion of said reinforcing members secured to said body shell.
Claim 11
Dependent Claim
18 words
The railway tank car set forth in claim 8, wherein said bars each have a rectangular cross section.
Claim 12
Dependent Claim
33 words
The railway tank car set forth in claim 8, wherein said bars each have a rectangular cross section, said bars in use being disposed with the longer cross-sectional dimension thereof positioned substantially vertically.
