Each burner has a supply air tube the inlet end of which is obstructed by a coil spring which is variably expanded to act as an adjustable shutter regulating the amount of air that enters through its turns in response to actuation of the gas control valve for the burner. The burners have center simmer sections for low heat and single gas lines with port controlled terminals which variably direct the gas to the center simmer sections or to the main burner sections depending upon the rate of delivery of the same. A safety circuit prevents flow of gas to the range except when exhaust fans are properly operating, and a taut wire exposed to heating by all burners expands when any is above a selected temperature to signal such condition.,下面是Gas smooth top range专利的具体信息内容。

1. In a gas burner having a center port section and an outer port section, a gaseous fuel supply line having a terminus at the burner with lateral discharge orifices, a surround for said terminus spaced therefrom and having orifices respectively in alignment with the terminus orifices, the surround continuing to an outlet proximate to the center burner section, and enclosure means about the surround extending to the region of the outer port section, with fuel issuing at relatively low velocity from the terminus orifices being confined in and proceeding through the surround to the center section and at relatively high velocity being forced outwardly through the surround orifices for supply to the outer burner section through the enclosure means.
2. A gas burner as set forth in claim 1, wherein the enclosure means has an air supply for mixing therein of the gaseous fuel and combustion air, and there is communication between the enclosure means and the interior of the surround for air supply to the latter in the delivery of the low velocity fuel through the same to the center burner section.
3. A gas burner as set forth in claim 1, including a heat bridge within the burner extending from a port section thereof to the fuel supply line to raise the temperature of the fuel and thereby effect a relative reduction in its weight as the burner temperature rises.
