Abstract
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.

Claim 1
Independent Claim
199 words
A grate comprising a log-supporting portion and a log-retaining portion, said log-supporting portion comprising a plurality of spaced apart members disposed at an angle of 20° to 30° to the horizontal, said retaining portion extending from said supporting members at an angle therewith of essentially 90°, said supporting members being spaced apart a sufficient distance to allow embers from logs in said 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 said grate, and a removable plate-like wall member disposed over said retaining portion, and legs supporting said grate above a base plane a sufficient distance to permit buildup of an ember bed on the base plane beneath said supporting portion while leaving a defined space between the underside of said log-supporting portion and a formed ember bed whereby embers from said grate will fall from said grate essentially in front of said retaining portion, said plate-like member having end flanges which fit about the ends of said log-retaining portion.
Claim 2
Dependent Claim
199 words
A grate comprising a log-supporting portion and a log-retaining portion, said log-supporting portion comprising a plurality of spaced apart members disposed at an angle of 20° to 30° to the horizontal, said retaining portion extending from said supporting members at an angle therewith of essentially 90°, said supporting members being spaced apart a sufficient distance to allow embers from logs in said 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 said grate, and a removable plate-like wall member disposed over said retaining portion, and legs supporting said grate above a base plane a sufficient distance to permit buildup of an ember bed on the base plane beneath said supporting portion while leaving a defined space between the underside of said log-supporting portion and a formed ember bed whereby embers from said grate will fall from said grate essentially in front of said retaining portion, said plate-like member having end flanges which fit about the ends of said log-retaining portion.
Claim 3
Dependent Claim
