Abstract
Abstract A mixing and dispensing wagon having side-by-side lower longitudinal augers moving material away from the end walls and a pair of upper longitudinal augers moving material toward the end walls such that the material is recirculated for mixing away from the ends on the bottom, upwardly and toward the ends at the top, then downwardly and back to the center area. A discharge conveyer is in communication with the material chamber near the lateral center of the chamber on a level with the lower augers. The upper augers have paddles at the ends adjacent the end walls thereby preventing compacting of the material against the end walls and also to force the material downwardly. One lower conveyer includes conveyer portions spaced apart at its inner ends by a plurality of paddles.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
219 words
A material mixer, comprising, an elongated container having a mixing chamber. an unloading means positioned forwardly of the transverse center of said chamber and in communication with said chamber adjacent its bottom, a first conveyor adjacent the bottom of said chamber and having oppositely extending conveyor portions which meet at their inner ends on the transverse center line of said unloading means forwardly of the transverse center line of said chamber for moving material towards said unloading means from opposite ends of said chamber, a second conveyor positioned in said chamber above said first conveyor and having oppositely extending portions which meet at the transverse center line of said chamber for moving material in opposite directions away from the transverse center of said chamber, a third conveyor positioned inside-by-side relationship to said first conveyor adjacent the bottom of said chamber and having oppositely extending conveyor portions which meet at their inner ends rearwardly of the transverse center line of said chamber for moving material towards a transverse plane in said chamber positioned rearwardly of the transverse center line, and a fourth conveyor positioned in said chamber above said third conveyor and having oppositely extending portions which meet at the transverse center line of said chamber for moving material in opposite directions away from the transverse center of said chamber.
