Abstract
Abstract An intermediate structure for efficiently joining adjacent ends of a pair of coupled open-top hopper car bodies for carrying bulk materials such as coal, and thereby forming a single articulated hopper car of large capacity. The car is continuously loadable from end to end, is exceptionally stable in transit even when fully loaded and at normal speeds, and is substantially leakproof at joints even while negotiating sharp curves in track.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
196 words
The combination, in an articulated railway car comprising a pair of coupled-together open-top hopper car bodies, each of said car bodies including an upwardly sloping floor and sidewalls, the adjacent marginal edges of said sidewalls being spaced apart, wherein the improvement comprises: a. an inverted V-shaped cross ridge member the ends of which rest upon and slidably connect the sloping floors, b. an elongated rigid member extending laterally beneath and supporting the center of said cross ridge member, c. pivotally mounted oppositely inclined outer suspension members having variable included angles controlled by track curvature and extending respectively from adjacent ends of said sidewalls to said rigid member, d. side closure sheets slidably engaging adjacent sidewalls and closing the space between the car bodies, e. the bottom portion of said side closure sheets being extended inwardly so as to rest slidably upon said V-shaped cross ridge member, f. bridging members mounted to adjacent sidewalls of the car bodies through resilient mounting means, said bridging members having guide means to center the side closure sheets with respect to the sidewalls, and g. resilient means for urging said side closure sheets against the sidewalls of the respective car bodies.
Claim 2
Dependent Claim

The combination, in an articulated railway car comprising a pair of coupled-together open-top hopper car bodies, each of said car bodies including an upwardly sloping floor and sidewalls, the adjacent marginal edges of said sidewalls being spaced apart, wherein the improvement comprises: a. an inverted V-shaped cross ridge member the ends of which rest upon and slidably connect the sloping floors, b. an elongated rigid member extending laterally beneath and supporting the center of said cross ridge member, c. pivotally mounted oppositely inclined outer suspension members having variable included angles controlled by track curvature and extending respectively from adjacent ends of said sidewalls to said rigid member, d. side closure sheets slidably engaging adjacent sidewalls and closing the space between the car bodies, e. the bottom portion of said side closure sheets being extended inwardly so as to rest slidably upon said V-shaped cross ridge member, f. bridging members mounted to adjacent sidewalls of the car bodies through resilient mounting means, said bridging members having guide means to center the side closure sheets with respect to the sidewalls, and g. resilient means for urging said side closure sheets against the sidewalls of the respective car bodies.
Claim 3
Dependent Claim
29 words
The combination as claimed in claim 1, wherein the guide means of subparagraph (f) comprises end stop lugs on the bridging members for engaging adjacent edges of the sidewalls.
Claim 4
Dependent Claim
29 words
The combination as claimed in claim 1, wherein the resilient means of subparagraph (g) comprise leaf spring means connected to said side closure sheet and slidable upon adjacent sidewalls.
Claim 5
Dependent Claim
19 words
The combination as claimed in claim 1, wherein the resilient mounting means of subparagraph (f) comprises rubber shear pads.
Claim 6
Dependent Claim
40 words
The combination as claimed in claim 1, wherein the resilient mounting means of subparagraph (f) comprises a metal helix having a middle spool portion rotatably secured to said bridging member and its ends in centering guides attached to adjacent sidewalls.
