Abstract

Abstract A screen to be attached to and suspended below a fireplace grate. The grate supports logs to be burned in the fireplace and as the logs burn, hot coals fall through the grate and are supported on the screen. The screen is sufficiently close to the grate such that the hot coals on the screen aid in igniting subsequent logs placed on the fireplace grate, and aid in the complete burning of partially burned logs on the grate.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 255 words
In combination with a fireplace grate of the type for supporting logs to be burned a first distance above the floor of a fireplace, said grate including a plurality of spaced apart log support members, each log support member having first and second ends, the improvement comprising a screen, and means for attaching said screen to said grate a second distance below said grate, said second distance being less than said first distance, so that when logs are burned on said grate, the hot coals which result from burning said logs fall from said grate and rest on and are supported by said screen; said second distance being sufficiently small so that hot coals aid in completely burning logs on the grate and aid in igniting unburned logs placed on said grate; and said first distance exceeds said second distance by a sufficient amount so that air can flow upwardly through said screen to maintain said hot coals burning; said screen attaching means including a pair of opposed spaced apart C-shaped channels, each of said channels including an upstanding base and spaced apart parallel upper and lower legs, said lower leg being provided with an elongated slot which extends substantially the full length of the channel to receive said screen, the first channel of said pair of channels being frictionally retained on the first ends of said plurality of log support members and the second channel of said pair of channels being frictionally retained on the second ends of said plurality of log support members.
Claim 2
Dependent Claim 255 words
