Patent ID: 7975605

Claim:
A food processing device comprising: a housing having a lid; an operating attachment supported in the housing for rotation about an axis of rotation; and a drive mechanism supported by the lid for rotating the attachment to process food in the housing, the drive mechanism comprising a manually rotatable actuator, and a drive transmission system coupling the actuator to the attachment to transmit a rotational driving force applied to the actuator to rotate the attachment, the drive transmission system comprising a first rotary member arranged to receive the rotational driving force from the actuator, a second rotary member in driving engagement with the first rotary member for receiving a driving force from the first rotary member to rotate the attachment;, wherein the first and second rotary members have corresponding serial formations of respective circular cross-sections that are inter-engageable, one in the other, for transmission of the driving force, and a ratchet device in driving engagement with the drive transmission system to enable transmission of the rotational driving force only in one direction, from the actuator to the attachment, upon the actuator rotating in one direction.
