Title: Device for operating air governing means at a refuse burning furnace

Abstract: Air admittance ports in the wall of a refuse burning furnace are provided with reciprocable sleeve members which in the first hand govern the air flow, but also may be used to scrape the ports free of deposits. These sleeves are interconnected in groups so they can be manipulated simultaneously for cleaning purposes, but nevertheless may be adjusted individually as well as group-wise for flow governing purposes.
