Gas burner

Claim 1

An unvented, open-flame type room heater comprising: a. a container i. made of a refractory material, ii. having a chamber therewithin, and iii. having an open face on the top thereof; b. a plate i. made of a refractory material, ii. mounted in said container so as to divide the chamber therewithin into upper and lower volumes, and iii. having a myriad of tiny passageways therein leading from the lower volume to the upper volume; c. means for introducing gas and air into the lower volume; d. a plurality of bars i. made of refractory material, ii. spanning the open face of said container in parallel, spaced array, and iii. shaped such that the sides of their longitudinal cross sections converge towards the chamber in said container; and e. a plurality of simulated logs i. located on top of said plurality of bars in generally parallel relationship thereto and ii. in contact with adjacent logs along portions of their exteriors, but leaving passageways therebetween, whereby, when the heater is being used, the gas and air passes through the myriad of tiny passageways in said plate and is burned in three separate locations, namely, between said plate and said plurality of bars, in the spaces between adjacent ones of said plurality of bars, and in the passageways between adjacent ones of said plurality of simulated logs, thereby virtually eliminating the passage of carbon monoxide into the surrounding atmosphere.
