Abstract

A vehicular body for hauling materials, comprising an external skeletal frame of metal members forming the primary load-bearing structure of the body; a metal lining supported by the skeletal frame and forming the interior surfaces of the body for containing loads of material, the exterior surface of the lining being exposed to the ambient atmosphere through the openings in the skeletal frame; and coupling devices securing the lining to the skeletal frame while permitting relative movement between the lining and the frame so that the lining and the frame can expand and contract differentially without stressing each other. The lining of the vehicular body is preferably detachably coupled to the skeletal frame to facilitate removal of the lining for maintenance or replacement purposes.

Claims

1. A vehicular body for hauling hot materials comprising

an external skeletal frame of metal members forming the primary load-transmitting structure of the body,

a removable metal lining supported by said skeletal frame and forming the interior surface of the body for containing loads of hot material, the exterior surface of said lining being exposed to the ambient atmosphere through the openings in said skeletal frame for dissipating heat from loads of hot material, and

coupling means securing said lining to said skeletal frame while permitting relative movement between said lining and said frame so that said lining and said frame can expand and contract differentially without stressing each other said coupling means comprises a plurality of retaining elements fastened to said lining and extending outwardly therefrom to engage an adjacent portion of said skeletal frame to hold said lining capative on said frame, said retaining elements permitting relative movement between said frame and said lining.

2. A vehicular body as set forth in claim 1 which includes means for limiting thermal conduction between said skeleton frame and said lining to minimize the temperature cycling of said frame.

3. A vehicular body as set forth in claim 2 wherein said means for limiting thermal conduction comprises spacers which limit the area of direct contact between said frame and said lining.

4. A vehicular body as set forth in claim 1 wherein said coupling means comprises means for normally holding said lining spaced away from said frame.

5. A vehicular body as set forth in claim 1 wherein said coupling means comprises a plurality of retaining elements fastened to said lining and extending outwardly therefrom around an adjacent portion of said frame to hold said lining captive on said frame, said retaining elements permitting relative movement between said frame and said lining along at least two mutually perpendicular axes.

6. A vehicular body as set forth in claim 5 wherein said mutually perpendicular axes are both parallel to the plane of said lining.

7. A vehicular body as set forth in claim 5 wherein one of said mutually perpendicular axes is parallel to the plane of said lining and the other of said axes is perpendicular to the plane of said lining.

8. A vehicular body as set forth in claim 1 wherein said coupling means comprises a plurality of retaining elements extending through portions of said frame, said retaining elements permitting relative movement between said frame and said lining along at least two mutually perpendicular axes.

9. A vehicular body as set forth in claim 1 wherein said coupling means are fastened to said lining by removable fastening means to facilitate the removal of said lining from said skeletal frame for maintenance or replacement purposes.

10. A vehicular body as set forth in claim 1 wherein said lining comprises a plurality of different plates each of which is free to expand and contract relative to adjacent plates.

11. A vehicular body as set forth in claim 10 wherein at least certain pairs of adjacent plates overlap each other in sliding contact so that the plates can expand and contract relative to each other.

12. A vehicular body for hauling materials comprising

an external skeletal frame of metal members forming the primary load-transmitting structure of the body,

a metal lining supported by said skeletal frame and forming the interior surface of the body for containing loads of material, said lining covering the openings in said skeletal frame, and

coupling means for detachably fastening said lining to said skeletal frame so that said lining can be removed from said frame for maintenance or replacement purposes, said coupling means comprises a plurality of retaining elements fastened to said lining and extending outwardly therefrom to engage an adjacent portion of said skeletal frame to hold said lining capative on said frame, said retaining elements permitting relative movement between said frame and said lining.

13. A vehicular body as set forth in claim 12 which includes means for limiting thermal conduction between said skeleton frame and said lining to minimize the temperature cycling of said frame.

14. A vehicular body as set forth in claim 13 wherein said means for limiting thermal conduction comprises spacers which limit the area of direct contact between said frame and said lining.

15. A vehicular body as set forth in claim 12 wherein said detachable fastening means couples said lining to said skeletal frame while permitting relative movement between said lining and said frame so that said lining and said frame can expand and contract differentially without stressing each other.

16. A vehicular body as set forth in claim 12 wherein said lining comprises a plurality of metal plates each of which is free to expand and contract relative to the other plates.

17. A vehicular body for hauling materials comprising

an external skeletal frame of metal members forming the primary load-transmitting structure of the body,

a metal lining supported by said skeletal frame and forming the interior surface of the body said covering the openings in said skeletal frame for containing loads of material,

said lining being formed by a plurality of metal plates which are free to expand and contract relative to each other, and

coupling means for detachably fastening each of said lining plates to said skeletal frame said coupling means comprises a plurality of retaining elements fastened to said lining and extending outwardly therefrom to engage an adjacent portion of said skeletal frame to hold said lining captive on said frame, said retaining elements permitting relative movement between said frame and said lining.
