  • Publication number: 20070137504
    Abstract: A salad spinner has a housing with a lid, a rotatable basket, and a drive mechanism in the lid for rotating the basket to spin water off salad in the basket. The drive mechanism has a manual actuator and a gear train for transmitting drive from the actuator to rotate the basket. The actuator lies on an outer surface of the lid and is movable along the outer surface in opposite directions between first and second positions to rotate the basket in a single direction. A ratchet assembly in driving engagement with the gear train enables transmission of rotational drive only in the single direction. A braking mechanism is included for braking spinning of the basket, and has a manual operator and two braking shoes for movement by the operator to brake spinning of the basket by friction.

  • Publication number: 20070033814
    Abstract: A can opener has two pivotable handle members and a traction wheel and a rotary cutter movable by the handle members respectively between an inoperative position in which the wheel and cutter are spaced apart for mounting onto a can and an operative position in which they are close together for turning and cutting the can. An operating lever is pivotable back and forth. A first ratchet assembly is driven by the lever upon pivotal movement in one direction for rotating the wheel in one direction. There is also a second ratchet assembly driven by the lever upon pivotal movement in the opposite direction for rotating the wheel in the same direction. Upon pivotal reciprocation, the lever rotates the wheel in the direction operating the wheel and cutter continuously, turning and cutting the can.
