Patent number: 7975605Abstract: A food processing device, e.g. a salad spinner, has a housing with a lid, a basket supported in the housing for rotation, and a drive mechanism supported by the lid for rotating the basket to spin water from salad in the housing. The drive mechanism has a crank handle and a drive transmission system coupling the handle to the basket to transmit a rotational driving force from the handle to rotate the basket. The drive transmission system has a first rotary gear arranged to receive the rotational driving force from the handle and a second rotary gear in driving engagement with the first gear for receiving the rotational driving force from the first gear to rotate the basket. The first and second gears have corresponding serial formations, e.g., recesses and protrusions, of respective circular cross-sections that are inter-engageable, one in the other, for transmission of the driving force.Type: GrantFiled: February 26, 2008Date of Patent: July 12, 2011Inventors: Yiu Chung Wan, Lance Logan Hood

Patent number: 7681495Abstract: A food processing device has a housing with a lid, a rotatable attachment (e.g., a basket or beater) in the housing and a drive mechanism in the lid for rotating the attachment to process food in the housing. The drive mechanism has a manual actuator and a gear train for transmitting a driving force from the actuator to rotate the attachment. The actuator lies on an outer surface of the lid and is movable along the lid surface in opposite directions between two positions to rotate the attachment in a single direction. A ratchet assembly in driving engagement with the gear train transmits a rotational drive in only a single direction. A braking mechanism for braking the attachment, includes a manual operator and two braking shoes for movement by the operator to brake the attachment by friction.Type: GrantFiled: August 3, 2006Date of Patent: March 23, 2010Inventors: Yiu Chung Wan, Lance Logan Hood
