Abstract
An electric mixer for selectively rotating a pair of cooperating beaters, the mixer comprising a housing defining a cavity having an axis extending between first and second ends thereof, a motor disposed in the cavity generally coaxial with the cavity axis, the motor including an axial drive shaft and a drive gear fixed to the second end of the drive shaft, a gear case fixed to the second end of the motor, the gear case including a pair of integral, depending tubular shafts having rotation axes substantially parallel to each other and to the cavity axis, each tubular shaft having a bore open at the first and second ends thereof. The mixer further includes a drum coaxially disposed on each tubular shaft for rotation about the respective rotation axis, each drum including a driven gear integrally formed at the first end thereof and structure at the second end thereof for releasably engaging the shaft of one beater, the driven gears being in meshing engagement, and a reduction gear rotatably supported by the gear case, the reduction gear being driven by the drive gear and driving only one driven gear. The mixer further includes an ejector slidably disposed for axial movement in the cavity, the ejector having a first end projecting through an opening in the housing for manual actuation and a second end including a pair of depending rods, one rod being disposed in the bore of each tubular shaft through the open first end thereof for engaging the first end of the shaft of one beater.
