Abstract
Abstract In an apparatus for directing material from a blower pipe line onto a stove surface or into an enclosed space, a rotating deflecting flap is positioned in the path of the material issuing from the discharge end of the pipe line for distributing it in a uniform manner. The deflecting flap is positioned outwardly from the discharge end of the pipe line and extends in a downwardly inclined fashion so that its surface extends into the path of the material flowing from the pipe line. Further, the deflecting flap is not only rotatable about the axis of the discharge end of the pipe line but is angularly displaceable relative to the pipe line axis for varying the manner in which the material is directed from the flap. To provide the desired movement of the deflecting flap, a pair of wind wheels are provided in the path of the discharge end of the pipe line on opposite sides of the discharge axis, and motion transmission means are connected between the wind wheels and the deflecting flap. The wind wheels are pivotally supported so that they can be arcuately displaced outwardly from the axis of the discharge end of the pipe line.
