Hand-operated mixing device

A hand-operated mixing device comprising a mixing drum, having an open end, a closed end, and an outer periphery radially spaced from an axis of rotation passing through said ends, said outer periphery being formed by divergently tapered circumferential walls extending from said ends to an enlarged diameter portion intermediate said ends, means providing an annular groove at the outer periphery of said enlarged diameter portion, and the closed end having a detachably mounted crank member terminating in a bearing shaft coaxial with the drum axis, said drum being detachably mounted on a light-weight frame having spaced forward and rear portions disposed perpendicularly to said drum axis, said frame having at the forward portion thereof transversely spaced rollers for engagement with said annular groove, and at the rear portion thereof a bearing orifice detachably receiving the bearing shaft of said crank handle, the positioning of said rollers and bearing orifice being such as to orient the drum axis at an angle of about 10.degree.-20.degree. to the horizontal to thereby elevate the open end of the drum, said light-weight frame being of knockdown construction having parts of such dimension as to permit packing when disassembled in a container adapted to closely receive said mixing drum, and said light-weight frame, when assembled, having wheels at the base of said frame and a handle at the rear portion thereof facilitating transport of the mixing drum and contents.
