Abstract
A barbecue grill with a housing member that defines a rectangular compartment where a food supporting assembly and a heat source assembly are housed in a variable spaced apart relationship. The food supporting assembly includes typically a shaft through which food items are inserted and grills where they are broiled. The shaft is driven through an electric motor. The heat source assembly is suspended from a pair of steel wire elements that are wound on a bar and directed through pulleys in order to uniformly lift or power the heat source assembly through a reversible electric motor. Normally closed switches are connected in series with the power connections for each direction of rotation of the reversible motor and physically located where they are actuated by the heat source assembly to interrupt it, travel.
