  • Coal stove
    Patent number: 4290410
    Abstract: A steel-bodied, coal burning stove is provided with an improved combustion system including a one-piece fire pot having an integral, non-shakeable grate. The pot is mounted in the lower regions of the stove and is suspended by a circular mounting ring arrangement which defines the interior of the stove into upper and lower chambers. The pot projects downwardly from the mounting ring arrangement into the lower of the stove chambers. The mounting ring arrangement is constructed to enable air to flow directly from the lower chamber, peripherally about the pot to the upper chamber, bypassing the grate and means are provided to vary the flow of such bypass air.
