Abstract:
1. A rotary air lock pump mechanism comprising: a) a material feed bowl with a plurality of chambers, said bowl being configured for rotational movement around a central axis of said bowl and a power source to rotate said bowl about said axis; b) a collection barrel positioned over an open end of said bowl with a central axis of said barrel being congruent with said central axis of said bowl, said barrel remaining fixed while said bowl rotates about said central axis, said barrel directing flowable material deposited in an end of said barrel opposite said bowl into exposed ends of said chambers of said bowl; c) an air intake material ejection manifold that when positioned in a receiving recess on said barrel is serially presented to an open end of each chamber of said bowl as said bowl is rotated about said central axis and wherein when air is injected into an air receiving portion of said manifold it is injected into a chamber of said bowl being presented to said manifold and thereby causing flowable material deposited in said chamber to be ejected out through a material ejection portion of said manifold; d) a wear gasket positioned between a first side of a faceplate of said manifold and said bowl, said gasket facilitating smooth rotation of said bowl; e) a pressure mechanism engagedly positioned against a second side of said face plate to assure even wear of said wear gasket and to thereby maintain a suitable seal between said face plate of said manifold and said bowl; said pressure mechanism being operated by an incompressible fluid to exert an adjustable constant-pressure force against said face plate; and f) wherein as said bowl rotates flowable material is deposited through said barrel into a portion of said chambers, the ends of which are exposed in said barrel and as each chamber is serially presented to said manifold, by rotation of said bowl, the flowable material is ejected by said manifold.
