Patent number: 8316836Abstract: Two main embodiments of a heat shield for a barbecue grill are disclosed herein. Both are designed to reduce the transfer of heat from the heated volume of the cooking chamber to the handle of the barbecue grill. The first embodiment mounts to the exterior of the cooking chamber and is disposed between the cooking chamber and the handle. The first embodiment is contoured to interrupt the convective flow of heated air away from the handle. The second embodiment mounts to the interior of the cooking chamber opposite the handle. The second embodiment rests adjacent the inside surface of the cooking chamber to form a partially or substantially closed volume that serves as an insulating barrier for the handle.Type: GrantFiled: October 8, 2009Date of Patent: November 27, 2012Assignee: Weber-Stephen Products Co., Inc.Inventors: James Grasso, Ewald Sieg, Charles Choi, Anthony A.

Patent number: 6354548Abstract: The present invention provides a shelf assembly for a cooking apparatus such as a barbeque grill, and method of using same. The shelf assembly has a shelf component which can rotate about a generally horizontal axis of rotation located generally at a first end of the shelf component, from a lowered position to a raised position. The cooking apparatus or an associated apparatus has a frame member which supports the first end of the shelf component about the axis of rotation. The shelf assembly also has a support extending downwardly in relation to the shelf component when the shelf component is in the raised position. The support is capable of rotating about the axis of rotation with the shelf component. The shelf assembly further has a stationary coupler located generally below the axis of rotation in the vicinity of where the support is capable of rotating about the axis of rotation with the shelf component.Type: GrantFiled: August 13, 1999Date of Patent: March 12, 2002Assignee: Weber-Stephen Products CompanyInventors: Robert T.

Patent number: 6148668Abstract: An apparatus for indicating the amount of fuel in a fuel tank for a barbecue grill is disclosed. The apparatus includes a first housing member having indicator marks on an indicator wall thereof, a second housing member slidably engaging the first housing member and further securing the fuel tank, and a spring member connected to the first and second housing members to provide a resistive force to oppose the downward movement force of the fuel tank. The second housing member has a gauge wall with openings such that the gauge wall at least partially overlies the indicator wall of the first housing member to progressively expose indicator marks through the openings. The exposed indicator marks provide a readout of the amount of fuel remaining in the fuel tank.Type: GrantFiled: March 2, 1999Date of Patent: November 21, 2000Assignee: Weber-Stephen Products Co.Inventor: Ewald Sieg
