Abstract
An aerial dispensing apparatus is detachably mounted under each wing of an aircraft for adhesively coating and dispensing flakes containing an insect control substance. The apparatus includes an aerodynamically styled liquid adhesive supply chamber secured to the forward end of a detachable support frame and a flake storage container movably supported on the rear portion of the frame for movement rearwardly of the trailing edge of the wing to facilitate filling of the container. The container is provided with a bottom opening which communicates with an electrically driven auger for metering a supply of flakes to a mixing chamber. An electrically driven pump supplies a metered amount of liquid adhesive to the mixing chamber. A propeller driven mixing blade is rotatably mounted in the mixing chamber to facilitate the coating of the individual flakes with adhesive and for impelling the flakes rearwardly through the open end of the mixing chamber. A spinner is rotatably mounted adjacent the open end of the mixing chamber to aid in dispersing the adhesively coated flakes.
