Abstract

Abstract A reversible foot for the lower end of an inclined brace in a railway hopper car is a metal forging arched transversely to fit over a crossridge in the car, to which the foot is fastened. The foot is provided with a central vertical opening extending lengthwise of it for receiving the lower end of a brace inclined at a predetermined angle. The end wall of that opening that will be beside the upper inclined surface of the lower end of the brace is inclined substantially parallel to that surface, but the opposite end wall of the opening is inclined in the opposite direction at a different angle so that it will lie substantially parallel to the upper inclined surface of the lower end of a brace inclined at a different angle than the first-mentioned brace if the foot is reversed to receive such a brace. Whichever brace is used, its lower end is welded to the foot.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 202 words
A reversible foot for connecting to a railway hopper car crossridge the lower end of an inclined brace, said foot being a metal forging arched transversely to fit over a crossridge and having holes in its opposite sides for fasteners to hold it in place, the foot having a central vertical opening therein extending lengthwise of the foot for receiving the lower end of an inclined brace, said opening having spaced inclined end walls converging upwardly at two different predetermined angles for location beside the opposite inclined surfaces of the lower end of a brace in said opening inclined at one of said angles, with an end wall of said opening disposed substantially parallel to the upper inclined surface of the lower end of the brace, the inclination of the other of said end walls being such that if the shoe is turned end for end to receive a different brace inclined at the other of said predetermined angles said other end wall will lie substantially parallel to the upper inclined surface of the lower end of said different inclined brace, and the foot being adapted to be welded to the lower end of whichever inclined brace is disposed in said opening.
Claim 2
Dependent Claim 202 words
A reversible foot for connecting to a railway hopper car crossridge the lower end of an inclined brace, said foot being a metal forging arched transversely to fit over a crossridge and having holes in its opposite sides for fasteners to hold it in place, the foot having a central vertical opening therein extending lengthwise of the foot for receiving the lower end of an inclined brace, said opening having spaced inclined end walls converging upwardly at two different predetermined angles for location beside the opposite inclined surfaces of the lower end of a brace in said opening inclined at one of said angles, with an end wall of said opening disposed substantially parallel to the upper inclined surface of the lower end of the brace, the inclination of the other of said end walls being such that if the shoe is turned end for end to receive a different brace inclined at the other of said predetermined angles said other end wall will lie substantially parallel to the upper inclined surface of the lower end of said different inclined brace, and the foot being adapted to be welded to the lower end of whichever inclined brace is disposed in said opening.
Claim 3
Dependent Claim 71 words
A foot according to claim 1, in which the vertical thickness of the foot at the end thereof that has the more steeply inclined of said upwardly converging end walls is less than the vertical thickness of the opposite end of the foot, and the foot has an upper surface surrounding said central opening that slopes downwardly from said thicker end of the foot to the other end of the foot
Claim 4
Dependent Claim 37 words
A foot according to claim 2, in which the angle that the slope of said upper surface makes with the horizontal is one-half the difference between the angles that said inclined end walls make with the vertical.
