Abstract
A quick-connect coupling facilitates the connection of an auger of a dispensing mechanism to the drive shaft of the dispensing mechanism so as to firmly lock the auger from radial, axial, or rotational movement with respect to the drive shaft while inhibiting contamination and facilitating cleaning. The coupling includes a male portion provided on the auger shaft and including one or more pins, a female portion formed in the adapter shaft and including one or more axial and peripheral slots, and a key which firmly locks the pin in the peripheral slot. The key includes a retainer which is affixed to a sleeve or other device serving as a guide and support for the retainer. Upon downward movement of the sleeve along the drive shaft, the retainer acts as a cam to lock the pins in position. If the dispensing mechanism employs an adapter shaft as the drive shaft, an improved quick-connect coupling may also be provided to attach the adapter shaft to the drive mechanism output shaft.
