Abstract

A dump body for a truck is provided having a plurality of longitudinal channel members extending along the floor of the body, a 45* upturned flange extending along the sides of the floor, said flange cooperating with a formed channel along the lower edge of the sides to provide a box rail along the corners of the box. Tapered buttresses extend from the top of the side walls down to the upper face of the corner rails merging smoothly with both. Cross supports extend from the lower inside face of the corner rail to the extended inner sills for the dump body, the supports also merging smoothly with both elements. The inner sills are extended downwardly to provide additional reinforcement at the point of the maximum stress and the extension of the cross supports, corner rails and buttresses form a full C-clamp structure in cross section for the box. An inside top rail is provided and plywood sheet insulation extends from the bottom thereof to the top of the edge flange of the floor. Heat is advantageously provided along the floor by introduction into a rear manifold adjacent the discharge edge of the box to give maximum effectiveness. A discharge manifold is provided adjacent the front of the box for release of the hot gases to the atmosphere.

Claims

1. A reinforced dump body including two side walls having a top and bottom edge and a floor adjacent the bottom edge, the improvement comprising a plurality of longitudinal reinforcement members extending underneath the floor and attached along the upper edges to said floor, a longitudinal flange turned upwardly at approximately 45* along the sides, an outside channel rail adjacent the bottom edge, one of said channel rail and said flange being formed integrally with a respective one of said floor and said side walls, said channel rail mating with said flange and forming substantially a rectangular corner rail, a plurality of laterally tapered side buttress members extending from the top edge of said side wall downwardly to the upper face of said rail and merging smoothly with both, at least one inner sill member of said reinforcement members adjacent the longitudinal center of said floor extending below the others and said side rail, and cross supports for interconnecting said reinforcement members tapering from the lower face of said cOrner rail to the outer side face of said inner sill member and merging smoothly with both, whereby a full C-clamp structure is formed in cross section for said body by said cross supports, corner rails and buttress members for maximum strength and rigidity of said body.

2. The dump body of claim 1 wherein is further provided a top rail extending along the upper side walls of said body, said top rail being positioned on the inside face of said side walls and comprising an inwardly directed integral lip on said side wall and an angle piece attached to form a box section therewith.

3. The dump body of claim 2 wherein there is further provided plywood sheet insulation attached to the inside face of said side walls, the upper edge of said sheet being in juxtaposition with the top rail and the bottom edge being positioned adjacent the raised outer edge of said flange, whereby the sheet is protected from water entering both the top and bottom edges.

4. The dump body of claim 1 wherein said longitudinal reinforcement members comprise at least two inner sill members, the outer side face of each sill member being substantially perpendicular to said floor, the inner side face extending at an oblique angle and having an angle reinforcement member attached thereto, said sill member and said angle reinforcement member foring two channel sections with a common middle leg for maximization of strength with a minimum of attachment edges.

5. The dump body of claim 1 wherein said outside channel rail and said flange forms a square corner rail in cross section.

6. The dump body of claim 1 wherein said reinforcement members include at least two inner sill members extending below the others and said corner rail, the outer face of said inner sill member being substantially perpendicular to the floor and extending downwardly below the other reinforcement members, the inner face extending to an oblique angle, said cross supports being attached only to the lower face of said corner rail, the outer face of said sill members, and the lowermost face of said other reinforcement members, said reinforcement members being generally channel shaped, an angle reinforcement member along the inner face of said inner sill member, and a center cross support attached to said inner faces of said sill members and the lowermost face of said angle members.

7. The dump body of claim 1 wherein said cross supports are formed of split I-beam sections, the end of the beam extending across substantially the full expanse of the lower side face of said channel rail, and the opposite end of said beam being attached to the outer side face of said inner sill members.

8. A dump body having two reinforced side walls and a reinforced floor comprising a plurality of longitudinal reinforcement channel members attached to and extending underneath the floor, outside channel rails formed integrally with the side walls, a transversely extending inlet manifold attached underneath said floor at the rear edge thereof, said corner rail, said reinforcement members and said manifold being enclosed on the top side by the floor to form gaseous product passageways with direct heat transfer to the floor, means to introduce hot gas into said inlet manifold, orifice means formed in said manifold and interconnecting with the rear ends of the longitudinal channel reinforcement members and said corner rail to allow flow of fluid from the rear edge forwardly along the length of the body and exhaust means at the forward end of said channel members and said corner rail to release the gas, whereby the maximum heating occurs along the rear edge of the floor at said manifold and the gas is thereafter transferred the length of the floor to the front.

9. The dump body of claim 8 wherein said exhaust means comprises an outlet manifold extending along the front edge of said floor and communicating with outlet orifices in the floor, and an exhaust pipe at the front of said body connected to said outlet manifold to exhaust the gasEs to the atmosphere.

10. The dump body of claim 8 wherein said inlet manifold is formed by a transverse channel, said channel having sufficient strength and rigidity to form a reinforcement for the rear edge of said floor, the depth of the channel being greater at the center than at the ends for maximum strength at the point of maximum stress.
