ABSTRACT:
A quick release grinding assembly is incorporated in a condiment grinder mill. A base receives and stores condiment pieces such as peppercorns. A head is mounted on the base for rotation relative to the base. An elongate shaft extends through the head and base and the shaft is secured to the head for rotation relative to the base. The grinding mechanism includes a grinder cone attached to the end of the shaft and a grinder ring mounted in the end of the base. A support ring is formed with an outer perimeter or ring secured to the base and a flexing inner perimeter or ring of flexible deformable material receives and centers the shaft. The inner rim deformable material has an initial configuration and memory for return to the original configuration after flexing deformation. The shaft is formed with projecting ears arranged to be forcibly passable through the inner rim of the support ring by flexing deformation of the inner rim for quick release disassembly and assembly of the grinding mechanism. A captive spring secured coaxially on the shaft spring biases the shaft. Complementary locking surfaces on the shaft top nut and condiment grinder mill head are spring biased in locking engagement for manually turning the head, shaft and top nut in phase.
