Abstract
Abstract This is an improvement in railway boxcars that include a floor, a top, two sidewalls and two end walls defining the cargo space in said boxcars. The hammering induced on the end walls of a boxcar cannot be strongly braced to resist blows imposed by heavy cargo. This invention comprises the inclusion of a detachable bulkhead laterally spanning the distance between sidewalls and located inwardly of at least one end wall of a boxcar. Thus, said bulkhead element may easily be removed, straightened, and after being repaired, reinstalled in a boxcar, to eliminate need for repair of distorted members while the bulkhead constitutes a part of the framework of said boxcar.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
An elongated railway boxcar having a body comprising a floor, top, two sidewalls and two end wall units joined together to define an enclosure for lading carried by said car, at least one of said end wall elements having a bulkhead element extending laterally across the enclosure, spaced inwardly of said end wall and joined to the floor element and to said end wall element by structural sections, arranged in vertical alignment with each other, said bulkhead element including plural vertical members, removably bolted to said structural sections, said vertical elements being symmetrical about a longitudinal centerline, both face-to-face as well as end-to-end, thus to accommodate replacement in said bulkhead element if they become deflected, said vertical members being I-beams having reinforcing members joining the edges of their top and bottom flanges, said reinforcing members lying parallel with the central beam web of said I-beam, and terminating short of said web at both ends of the latter.
Claim 2
Dependent Claim
157 words
An elongated railway boxcar having a body comprising a floor, top, two sidewalls and two end wall units joined together to define an enclosure for lading carried by said car, at least one of said end wall elements having a bulkhead element extending laterally across the enclosure, spaced inwardly of said end wall and joined to the floor element and to said end wall element by structural sections, arranged in vertical alignment with each other, said bulkhead element including plural vertical members, removably bolted to said structural sections, said vertical elements being symmetrical about a longitudinal centerline, both face-to-face as well as end-to-end, thus to accommodate replacement in said bulkhead element if they become deflected, said vertical members being I-beams having reinforcing members joining the edges of their top and bottom flanges, said reinforcing members lying parallel with the central beam web of said I-beam, and terminating short of said web at both ends of the latter.
Claim 3
Dependent Claim
14 words
The organization defined in claim 1 in which the structural sections are channel elements.
Claim 4
Dependent Claim
35 words
The organization defined in claim 1 in which the vertical members are I-beam top and bottom flanges at their edges and the reinforcing members lying generally parallel with the central beam web of said I-beam.
Claim 5
Dependent Claim
35 words
The organization defined in claim 3 in which the reinforcing members terminate short of the central beam web at both ends of the latter, to aid their attachment and detachment, with and from said bulkhead.
