  • Patent number: 4058108
    Abstract: A log-burning grate comprising a log-supporting portion and a log-retaining portion disposed at essentially ninety degrees to each other and supported by legs above a base plane with the support portion comprising a plurality of spaced apart members disposed at an angle of twenty to thirty degrees to the horizontal. A plate member is mounted to the retaining portion to control the position of the buildup of an ember bed, to slow the rate of burn, and to protect the back fireplace wall. The support members are spaced a sufficient distance to allow embers from logs in the grate to fall through and form a bed thereunder, the total area of spacing between said supporting members being substantially greater than the area of said supporting members so as to permit heat due to burning of logs in said grate to radiate outwardly from the front of the grate.
