摘要： An invertible/reversible tool (20) for use in a rotary food processing appliance (10) is provided for performing predetermined processing operations in a first position and other predetermin­ed operations in a second upside down position in a working bowl (16), which bowl contains a drive shaft for rotating the tool about a vertical axis in the bowl. The tool has an elongated upright hub (30) with first and second sockets (32, 34) positioned on opposite ends adapted to engage the drive shaft for rotating the upright hub in different directions depending on which socket is engaging the drive. Raised ridge keyways extending vertically for at least more than half the length of the upright hub are provided to provide a positive driving relationship between the upright hub and an encircling blade hub (40) which carries reversible blades (42, 44) extending outwardly relative to the axis of rotation from oppo­site sides of the blade hub. This blade hub is slidable axially along the elongated upright hub so that the blade hub will free­ly slide down to the lower end of the upright hub when the latter hub is inverted. The blades have first and second edges of differing characteristics which move in the same direction for performing first food processing operations and in a second direction for performing second food processing operations when the tool is turned upside down and coupled to the motor drive.

摘要： A switch (10) for providing a safety function when its main contacts are fused or stuck together in the "ON" position, comprising a housing (16) containing a pair of main contacts (42, 54), one being designated an ON contact, and the other main contact being carried by a movable switch arm (50) in the housing (16). This switch arm (50) has a first end which carries the movable main contact (54) and a second end, and spring means (56) mechanically coupled to the movable switch arm (50) normally bias the movable main contact (54) toward open position away from engagement with the ON contact. Switch operating means including movable actuator means (78) overcome the biasing force of the spring means (56) for moving the movable main contact (54) to closed position into engagement with the ON main contact. There are auxiliary safety contact means (60) within the switch housing for completing a safety circuit and/or for deenergizing the main circuit in response to abnormal movement of the movable switch arm (50) when the actuator means (78) is moved to OFF position, but the movable main contact (54) remains fused or stuck to the ON main contact.
