Abstract
A barbecue accessory for addressing flare ups, uneven heat distribution, and open lid heat loss features a series of spaced-apart longitudinal members connected together in a flexible endless loop having a width less than a first one of the length and width dimensions of a barbecue firebox. A closed loop drive system is arranged for mounting in the firebox between the bottom wall to engage the flexible endless loop to drive each of the spaced apart members of the flexible endless loop in a closed-loop path back and forth along a second one of the length and width dimensions of the firebox. At least one wiping member presents an upward facing wiping surface in the firebox beneath a moving path of the longitudinal members in close proximity thereto to clean the longitudinal members as they pass the wiping member.
