Hinged unloading auger for grinder-mixer

Claim 1

In a portable grinder-mixer having a wheeled frame, a tank for holding feed material being supported on the frame, a main unloading auger assembly mounted on the frame for swinging movement about vertical and horizontal axes, said unloading auger assembly including a first auger tube and a first auger mounted concentrically within said first tube, means to drive said first auger, and means for delivering feed material from said tank to said unloading auger assembly; the combination therewith of an extension auger assembly including a second auger tube and a second auger mounted concentrically within said second tube, means hingedly securing the second auger tube to the first auger tube about a generally vertical axis perpendicular to the tubes for swinging the extension auger assembly generally horizontally between a folded position and an extended position, fastening means on said auger tubes for securing said second auger tube along the side of said first auger tube when said second auger tube is in the folded position for movement together in vertical and horizontal directions, means operative to drivingly interconnect said first and second augers when said extension auger assembly is in its extended position, and adjustable support means connected to the upper side of said first auger tube to hold the main and extension auger assemblies in various positions of vertical adjustment over the arc of horizontal positions, the parts being so arranged and constructed that feed material may be discharged through the extension auger assembly when it is in its extended position and through the unloading auger assembly when the exteNsion auger assembly is in its folded position in the various vertical and horizontal positions.
