Abstract: The cooking grill disclosed has a series of inverted U-shaped channels for trapping hot convection gases beneath a substantially flat cooking surface. The channels are held together by one or more cross stringers which pass through sidewalls of each channel in apertures adjacent to a channel base and are secured to the channel base by securing means of various types. Sidewalls may be flared and exterior surfaces coated with an easily cleaned material. The stringers may be of various cross sections.

Abstract: A portable barbecue unit with a gas fired, vertically disposed heat source for roasting spit mounted foodstuffs. The vertical heat source includes an upstanding panel of radiant material extending along a tubular gas burner detachably mounted within the cooking enclosure to the side of the rotisserie spit. A modification combines the upstanding radiant panel with a horizontally disposed bed of radiant material underlying the spit and heated by an auxiliary gas burner.

Abstract: A portable gas-fired barbecue unit having a grate assembly for supporting a bed of ceramic coals between a gas burner and a cooking grill. The grate assembly includes upper stringers having a central channel to catch food drippings and side flanges to support the ceramic coals. Lower stringers with channels are arranged to catch any drippings missed by the upper stringers. All stringers are sloped toward one end where means is provided to collect the drippings. The assembly intercepts both food drippings and gas combustion products to produce radiant cooking energy and flavoring smoke while catching excess drippings to prevent fouling of the burner.
