Abstract
Abstract A center sill-less skeletonized gondola type of railway vehicle having framed reinforced receptacles for positioning and transporting cylindrical containers which are carried with their axis extending vertically of the vehicle. A low deck design is used to provide a low center of gravity and vehicle stability. Pivoted spring biased latching devices engage the top rim of each container to stabilize the containers in the storage well during movement of the vehicle.

Claim 1
Independent Claim
354 words
A railway car for carrying containers comprising reinforced high end deck portions at opposite ends of said car; an intermediate depressed deck portion extending between said end portions, transition portions connecting said opposite ends of said depressed deck portion with said high end portions, said high end deck portions including: end stub center sills with body bolsters extending therefrom, horizontal shear plates supported on said bolsters, deep beam end sills comprising vertical shear webs extending transversely and supported on said stub sills, transverse top and bottom beams connected to said vertical shear webs, and said bottom beam being connected to said vertical transverse shear webs and to said stub sills, High deck side sills including longitudinal transversely spaced top and bottom beam portions, vertical transversely spaced shear webs connected to said longitudinal top and bottom beam portions of said high deck side sills; said intermediate depressed deck portion having deep beam side sills including longitudinal top and bottom beam portions, deep vertical side shear webs connected to said longitudinal top and bottom beam portions of said depressed portion, said transition sections including top and bottom diagonal beams respectively connected to the top and bottom beam portions of said intermediate and end sections, and deep shear webs connected to said top and bottom diagonal beams and said shear webs of said intermediate and end portions, end bulkheads spaced longitudinally inwardly from said transverse end shear webs and connected to said longitudinal top and bottom beam portions of said high end sections thereby forming end container receptacles, intermediate bulkheads extending transversely of said vehicle and connected to said intermediate longitudinal top and bottom beams forming depressed deck container receptacles, container support members supported on said bottom beams in said container receptacles of said intermediate depressed portion, said shear webs and top and bottom beams connected thereto having a height corresponding substantially to the depth of containers in said receptacles, reinforcing members spaced within and connected to said receptacles adjacent the top beams, and hold down latches supported on said reinforcing means for engaging containers adjacent their upper ends thereof for securing the same within said receptacles.
Claim 2
Dependent Claim
354 words
A railway car for carrying containers comprising reinforced high end deck portions at opposite ends of said car; an intermediate depressed deck portion extending between said end portions, transition portions connecting said opposite ends of said depressed deck portion with said high end portions, said high end deck portions including: end stub center sills with body bolsters extending therefrom, horizontal shear plates supported on said bolsters, deep beam end sills comprising vertical shear webs extending transversely and supported on said stub sills, transverse top and bottom beams connected to said vertical shear webs, and said bottom beam being connected to said vertical transverse shear webs and to said stub sills, High deck side sills including longitudinal transversely spaced top and bottom beam portions, vertical transversely spaced shear webs connected to said longitudinal top and bottom beam portions of said high deck side sills; said intermediate depressed deck portion having deep beam side sills including longitudinal top and bottom beam portions, deep vertical side shear webs connected to said longitudinal top and bottom beam portions of said depressed portion, said transition sections including top and bottom diagonal beams respectively connected to the top and bottom beam portions of said intermediate and end sections, and deep shear webs connected to said top and bottom diagonal beams and said shear webs of said intermediate and end portions, end bulkheads spaced longitudinally inwardly from said transverse end shear webs and connected to said longitudinal top and bottom beam portions of said high end sections thereby forming end container receptacles, intermediate bulkheads extending transversely of said vehicle and connected to said intermediate longitudinal top and bottom beams forming depressed deck container receptacles, container support members supported on said bottom beams in said container receptacles of said intermediate depressed portion, said shear webs and top and bottom beams connected thereto having a height corresponding substantially to the depth of containers in said receptacles, reinforcing members spaced within and connected to said receptacles adjacent the top beams, and hold down latches supported on said reinforcing means for engaging containers adjacent their upper ends thereof for securing the same within said receptacles.
Claim 3
Dependent Claim
56 words
The invention in accordance with claim 1, including a longitudinal beam extension connected to each of said longitudinal bottom beam portions of said high deck side sills at the juncture of said diagonal transition beams and said longitudinal beam portions to thereby transmit horizontal forces from said high deck end portions into said depressed deck section.
Claim 4
Dependent Claim
36 words
The invention in accordance with claim 2, said longitudinal beam extension projecting between said top and bottom beam portions of said intermediate deck and being connected to said shear webs of said intermediate depressed deck portion.
