ABSTRACT:
A mixer particularly designed for light, domestic use is provided. The mixer includes a base frame, a mixing drum, and a handle, all of which are readily assembled and disassembled for easy transportation, even in an automobile. The drum is supported on the base frame with a three-point suspension, including an axle rotatably carried by the base frame and two rollers on the base frame which engage the drum in a position spaced from the axle toward a discharge opening of the drum. The drum is of one-piece construction and has a ring gear formed of integral, circumjacent teeth, with the axis of rotation of the drum and the gear being at an angle to the horizontal. An electric motor is mounted on the base frame directly below the drum and has a drive shaft parallel to the axis of rotation of the drum and gear with a pinion gear engagable with the integral, circumjacent drum teeth. The drum can be readily lifted off the base frame and the handle also can separated therefrom. Further, the base frame is designed with curved frame members which enable the entire mixer to be tilted to discharge the contents of the drum.
