Abstract
The invention is a lock for the bowl support of a food mixing machine. After the bowl is raised into the mixing position, the lock ensures that the bowl maintains its position and is not subject to creep. The mixing machine comprises a mixing head, a mixing bowl support for supporting a mixing bowl under the mixing head, a gear train for moving the bowl support and mixing bowl into position beneath the mixing head, and a lock which engages the gear train to prevent the bowl support from moving out of position beneath the mixing head during mixing. The lock is preferably a pawl which engages one of the gears in the gear train, preventing the bowl and the bowl support from moving out of position.
