ABSTRACT:
A portable hand-held concrete, mortar and gypsum mixer comprises a small gasoline powered implement having a drive shaft extending generally downward from the handles to a gear box. A transverse shaft driven by the drive shaft extends to either side of the gear box. Mounted on the transverse shaft are a plurality of blades shaped to thoroughly agitate and mix a combination of water and the ingredients for concrete, mortar, gypsum or similar heavy, hard to mix materials. Surrounding the blades are thin rings attached to the blades to form a round circumferential surface about the blades and thereby prevent the blades from directly contacting the mixing trough or other means of containing the mix. In the alternative, the plurality of blades may be shaped at their peripheries to form substantially continuous circular circumferences.
