Abstract: 1,179,164. A food steaming vessel with a two level rack. GENERAL ELECTRIC CO. 28 April, 1967 [19 May, 1966], No. 19712/67. Headings A4A and A4D. [Also in Divisions H1 and H5] The invention relates to an arrangement for supporting food to be steamed in a steaming vessel at two distinct levels within the vessel, the arrangement comprising a removable rack 33 for accommodating one or more food containers e.g. 35 and 36 on its top surface, the rack also having a pair of generally U-shaped support arms 44, 45 each having a crossmember 48, 51 substantially parallel to each other in a common plane and spaced apart from each other by a distance less than the distance between the opposite end edges of the rack; and a second food container 34 having a maximum length greater than the distance between the cross-members so that it is supported solely by the cross-members. The U-shaped support arms may each have a pair of legs (46, 47) pivotally connected to the rack and movable between a first position providing substantially unobstructed access to the top surface of the rack, and a second position for supporting the second food container, a stop means being provided for holding the support arms in the second position. A thermomagnetic device may be provided for terminating the heat supply when the food has been steamed. Water poured into the tray 16 is heated by an electric element which is energized when an actuator arm is moved to engage a magnet with a keeper plate made of thermoplastic material, where it is held by magnetic attraction until the water has boiled away. The temperature of the bottom of the vessel then rises and when the temperature of the keeper plate reaches its Curie point its magnetic permeability decreases and the magnet swings away from the keeper plate, thus breaking the circuit to the heater and striking a warning bell.
