  • Patent number: 7479295
    Abstract: A toaster including a housing with a toasting compartment, a heater located in the housing, a food cage movably supported in the toasting compartment for movement between a gripping position and a receiving position and a carriage movably supported in the housing. The carriage is permitted movement between a toasting position adjacent a lower portion of the toasting compartment and a loading position adjacent an upper portion of the toasting compartment. The carriage may receive and support a food item to be toasted in the loading position. The food cage is positioned in the receiving position when the carriage is positioned in the loading position and is positioned in the gripping position when the carriage is positioned in the toasting position. The food cage is urged toward the gripping position by gravitational forces as the carriage moves toward the toasting position.

  • Patent number: 6559423
    Abstract: An electric toaster includes a chassis with one or more toasting compartments. At least one electric heater is located in each compartment, and a cage is positioned in each compartment adjacent the heater. The cage includes lateral sides with a gap therebetween for receiving a food item and stationary supports that extend into the gap from the lateral sides for supporting the food item during a toasting operation. The electric toaster also includes a movable food support rod that is positioned in the toasting compartment for movement between an upper rest position and a lower toasting position below the stationary supports. The movable food support rod is adapted to support the food item above the stationary support and to transfer support of the food item to the stationary support when the movable food support rod travels below the stationary supports.

  • Patent number: 6486451
    Abstract: An electric toaster with a safety shut-off mechanism includes a carriage bracket with a user-manipulated knob that is movable between an upper rest position and a lower actuation position. A food support member is supported by the carriage bracket between the upper rest position and a lower toasting position. An electromagnet is connected to one of the chassis and the carriage bracket for holding the carriage bracket in the actuation position when the electromagnet is energized. A switch is movable to a closed position upon downward movement of the carriage bracket to the actuation position to energize the electromagnet and heating elements associated with the toaster. The carriage bracket is upwardly movable upon deenergization of the electromagnet to open the switch between the actuation position and the lower toasting position to deenergize the heating elements.

  • Patent number: 6380520
    Abstract: A safety shut-off device for an electric toaster having a food support member includes at least one switch that is movable between a closed position to thereby energize one or more heating elements associated with the toaster and an open position for deenergizing the at least one heating element. A rotatable support beam is pivotally connected to the chassis. An armature is connected to one end of the beam and a first locking member is connected to an opposite end of the beam. A second locking member associated with the food support member engages the first locking member during a toasting operation. During a toasting operation, the beam is rotated to close the at least one switch and an electromagnet is energized to hold the beam, and thus the food support member, in a toasting position. At the end of the toasting operation, the electromagnet is deenergized, causing the beam to rotate and open the switch to deenergize the at least one heating element and release the food support member.

  • Patent number: 6298772
    Abstract: A toaster having a ferromagnetic armature movable between an engaged position adjacent to a solenoid and closing a switch and a disengaged position away from the solenoid and opening the switch. A displacement assembly is adapted to move from an up position through a toasting position to a down position, whereupon the displacement assembly displaces the armature from the disengaged position to the engaged position, closing the switch and energizing a heating element and the solenoid, thus retaining the armature in the engaged position. The armature engages the displacement assembly when the armature is in its engaged position to retain the displacement assembly in the intermediate toasting position. A timer de-energizes the solenoid upon completion of toasting, releasing the armature to return to the disengaged position, thus opening the switch and causing de-energization of the heating element independently of the displacement assembly returning to the up position.
