Mixer apparatus

Abstract

A portable mixer includes a generally cylindrical housing open at one end thereof, and a mixer blade disposed to rotate within the housing. Located at the other end of the housing is a driven pulley coupled by a belt to a drive pulley mounted on a motor. The driven pulley is coupled through the end of the housing to the mixer blade so that when the driven pulley is rotated, the mixer blade is caused to rotate. The mixer blade includes an elongate, generally flat member which is disposed to rotate in a plane defined by the opening in the housing so that when the housing is placed upon a flat surface, the elongate member rotates just above the surface. The mixer blade also includes a second elongate, generaly flat member spaced from the first mentioned member and disposed to rotate adjacent the inside surface of the wall at the other end of the housing, and a third elongate, generally flat member which extends between the first and second members at one end thereof and is disposed to move adjacent the inside surface of the cylindrical walls of the housing. A switch is mounted in the housing to enable the operation of the motor when the housing is placed with the opening face down on a surface, and to disable the motor when the housing is lifted from the surface.
