Title: Soap stick launcher and method for launching soap sticks

Abstract: A stick launcher and method for launching soap sticks into a gas or oil well. The stick launcher comprises a containment vessel adapted to house the soap sticks, the containment vessel comprising a contiguous wall and a top and a bottom. A turret-style separator is positioned within the containment vessel, the separator comprising blades, and adapted to contain the soap sticks between the blades of the turret-styled separator and the contiguous wall of the containment vessel. A ball valve is positioned adjacent the bottom of the containment vessel, the ball valve, when in open position, adapted to be in fluid communication with a well bore and the containment vessel. A rotating assembly, when set in motion by an actuator, is used to rotate the separator and simultaneously open or close the ball valve. The rotating assembly comprises a ratchet mechanism and an actuator plate that, while acting on the separator to advance a soap stick into position in the passage way, opens and closes the ball valve so that the containment vessel and soap sticks have minimal contact with the moisture laden fluids of the well bore.
