Abstract

A multi-purpose vehicle for transporting material in bulk form such as trash, waste, and rubble or in packaged form such as, boxes, containers, pallet loads, and the like. An elongated walled vehicle body having a floor, an anti-friction surface on the floor, and twin side by side endless belts of reinforced neoprene, each having a top lay movable under load along said anti-friction surface and a bottom lay extending beneath the floor in engagement with a plurality of drive rollers. The drive rollers include two horizontally spaced rollers and a third roller spaced below and between the two rollers, the horizontally spaced rollers being spaced apart less than the diameter of the third roller therebeneath. A motor means carried beneath the floor drives through a common drive portion the set of three drive rollers for each belt.

Dependent claims

In a vehicle for hauling trash and solid waste material, the combination of:

a vehicle body including a body frame structure, an uninterrupted floor on said structure, and upstanding side walls;
a continuous uninterrupted sheet of anti-friction material secured to and substantially completely covering said floor and presenting a smooth top surface from side wall to side wall;
said anti-friction material being non-reactive to trash and waste material to be hauled;
an endless belt means of reinforced neoprene material having a top lay slidably movable along and supported on the major portion of the top surface of said anti-friction material and having a bottom lay movable beneath said floor;
idle rollers at opposite ends of the floor for supporting said endless belt means in non-driving engagement;
said body frame structure including depending frame means centrally between ends of said body frame structure for supporting belt drive means;
and drive means for said belt means supported by said depending central frame means below said floor and including
a pair of spaced drive rollers having surfaces frictionally engaging said bottom lay and with their axes lying in the same plane and parallel to the plane of the bottom lay,
a third drive roller below and between said pair of drive rollers and over which said bottom lay has frictional contact for more than 180.degree. about the axis thereof,
a motor means carried by said depending frame means for said drive means,
means for driving each of said drive rollers,
and reduction gear means carried by said depending frame means connecting said motor means and said means for driving said drive rollers.
