Abstract: An apparatus comprising a drive motor (7) with a shaft (8) having a front end for engaging a coupling device (20) for a whisk (10), and a rear end for engaging a drive (28) housed in a cylindrical body (31) and engageable by a mixing arm, as well as a vertically movable ejector member (51) linked to the coupling device. A movable mechanical assembly (70) is provided for releasing the ejector member (51) while blocking the internal space (74) in the body (31) so that only the whisk can be fitted, or alternatively locking the ejector member (51) in the down position while unblocking the internal space (74) in the body so that only the mixing arm can be fitted.

Abstract: A hand-held electric beater-mixer comprises a drive motor (7), two coupling devices (20, 28) linked to the motor and engageable by a whisk and a mixing accessory (38) respectively, an electrical switch (71) operated by a button (67) having an "off" position, a number of "continuous on" positions and a "selective on" position, a vertical movable ejector (51), and a mechanical assembly (72) for preventing continuous operation when the mixing accessory is in place. The mechanical assembly comprises a movable member (74) which releases the ejector when the whisk is in place. The ejector has an engagement tab (53) enabling operation of the button when the ejector is in the raised position, and locks the ejector (51) in the lowered position when the mixing accessory is in place. The engagement tab (53) of the ejector locked in the lowered position locks the button (67) on the side corresponding to its "continuous on" positions.

Abstract: A domestic mixer comprises a base (11) enclosing an electric motor (13) whose output shaft (15) projects from the base, as well as a bowl (18) adapted to be closed by a cover (20), mounted removably on the base (11) and having a rotatable tool (24) adapted to be coupled with the shaft (15) of the motor. The cover (20) and the upper edge (40) of the bowl (18) are interconnected by at least one bolt (44) secured to the cover (20) and connected, by a transmission member (46) actuable by the bolt, to a control member (48) movably mounted through the upper portion (16) of the base (11) between a working position to which it is brought when the cover (20) is locked by the bolt (44) and in which, under the action of the transmission member (46), it actuates a switch (50) adapted to permit the starting of the motor (13), and a rest position to which it is brought when the cover (20) is open and in which it does not actuate the switch (50), thereby to stop the motor (13).

Abstract: A domestic electrical appliance for food preparation has a generally cylindrical bowl and a vertical shaft rotatably mounted in this bowl. A beating/emulsifying tool of the invention is arranged to be mounted on the shaft. The tool comprises a disc arranged to extend near the bottom of the bowl and to be rotated by the vertical shaft. A series of radially directed projections are formed on one or both of the faces of the disc which can be used alone in the appliance for the preparation of emulsions such as mayonnaise. A cage can additionally be mounted in the bowl to cooperate with the disc for the effective beating of foodstuffs such as egg whites and cream.
