ABSTRACT:
A apparatus for maintaining precooked food at a desired temperature includes a stationary hollow housing mounted in the bottom part of a warmer for holding a quantity of food. The housing defines a cylindrical passage having an entrance through a wall of the warmer. A removable cylindrical member containing an electric resistance heater is inserted into the passage and is freely rotatable therein. A locking mechanism including a lug secured to a hub at the entrance of the housing and insertable into a circular guideway of a rotor attached to the outer end of the sleeve through a slot in the rotor secures the sleeve within the passage. A counterweight assembly on the sleeve applies a turning moment to the sleeve to automatically rotate the rotor into blocking engagement with the lug when the sleeve is fully inserted into the housing and released, thereby allowing the sleeve to rotate to a predetermined rest position wherein the lug in the guideway is displaced from the slot to lock the sleeve within the passage.
