Abstract
A material delivery assembly includes a delivery fitting attached to a drive shaft and including an outer wall that extends perpendicularly from a receiving surface. Apportioning slots are defined within the outer wall. A dispersion chamber is defined within the outer wall and the receiving surface. A material delivery conduit extends to a delivery port located within the dispersion chamber and is proximate the receiving surface of the delivery fitting. The material delivery port selectively delivers a viscous material to the receiving surface. The drive shaft and the delivery fitting are rotationally operated to define an apportioning state of the delivery fitting that is configured to manipulate the viscous material toward an inner surface of the outer wall. The apportioning slots in the apportioning state are configured to regulate passage of the viscous material from the dispersion chamber, through the outer wall and into a disk-shaped spread pattern.
