摘要： A fireplace grate is disclosed for supporting logs, or other fuel, and incorporating a gas burner integrally in the structure of the grate. As disclosed, a plurality of cradle members, of tubular metal stock are affixed to a pair of transverse, support rails which are formed of similar material and include downwardly turned extensions to define the legs of the grate. The tubular stock is of substantially square cross section, forming the grate so that the surfaces are offset from the horizontal to shed ash. One of the rails incorporates end closures to define a passage which is vented by a series of spaced-apart gas jets. A coupling apparatus is affixed to supply the passage with combustible gas, the apparatus incorporating a metering device for limiting the flow rate of gas into the passage.
