  • Rotary cheese grater with press plate seal
    Patent number: 6766972
    Abstract: A rotary hand grater has a housing which defines a hopper communicating with an open-ended cylindrical grating chamber in which a grating drum rotates for grating the contents of the hopper. The chamber is closed at one end by handle structure for rotating the grating drum and at the other end by a removable cap. A press plate is movable into and out of the hopper for pressing food against the grating tube. A flexible and resilient seal is clamped between the press plate and a backing surface on a plunger arm for sealing engagement with the hopper side walls and cooperation with the handle structure and the cap to seal the hopper and the chamber.

  • Rolling pin with counterweighted eccentric handles
    Patent number: 6585629
    Abstract: A rolling pin has a hollow cylindrical metal roller rotatable relative to an elongated shaft assembly extending axially through the roller, the shaft assembly having two rods respectively rotatably journaled in bushing portions of end caps on the roller, the two rods having their inner ends fitted in recesses in a weighted coupler disposed within the roller, and having outer ends offset from the rotational axis and connected to handles, each of which handles has a rounded side and a flattened side. The weight causes the handles to be disposed in an at-rest position with most of each handle disposed above the rotational axis and with the flattened sides of the handles facing downwardly.
