摘要： 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. With this arrangement, the heating elements are deenergized while the food support member is in the lower toasting position to thereby prevent further operation of the heating elements in the event of a food jam.

摘要： 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. A switch is positioned for activation by downward movement of the movable support from the stationary supports toward the lower toasting position to energize the electric heater. The switch is deactivated upon upward movement of the movable support from the lower toasting position toward the stationary supports to deenergize the at least one electric heater before reengagement of the movable support with the food item. In this manner, operation of the toaster can be stopped at the end of a toasting cycle independently of the presence or absence of a food jam.

摘要： 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.
摘要翻译：具有铁磁衔铁的烤面包机可以在与螺线管相邻的接合位置和闭合开关之间移动，并且脱离位置远离螺线管并打开开关。位移组件适于从上部位置通过烘烤位置移动到向下位置，于是位移组件将电枢从脱离位置移动到接合位置，闭合开关并激励加热元件和螺线管，从而保持衔铁处于接合位置。当电枢处于其接合位置时，电枢接合位移组件，以将位移组件保持在中间烘烤位置。定时器在完成烘烤时使电磁铁断电，释放电枢返回到脱离位置，从而打开开关并且使发热元件的断电独立于位移组件返回到向上位置。
