Abstract:
1. A drain control system for sinks and other fluid retaining vessels, each having a drain opening, said system comprising: an elongated tubular member comprising an open top and open bottom and having a longitudinal vertical axis and a horizontal axis perpendicular to the vertical axis; connection means at the top of the tubular member for attaching the tubular member to a sink, below the drain opening; a ball valve being rotatably mounted between a closed position and an open position within the tubular member, said ball valve having a centrally extending through channel; a sleeve element located within the tubular member, said sleeve element at all times seated up against the ball valve and extending up from the ball valve adjacent to and along the internal surface of the tubular member; rotatable shafts mounting and supporting the ball valve to the tubular member; a linkage assembly connected to one of the rotatable shafts for rotating the shaft and ball valve mounted thereon; and an actuator arm connected to the linkage assembly and extending outward from the tubular member and having vertically upward movement such that the arm is raised vertically from a horizontal position perpendicular to the vertical axis of the tubular member, to a raised position located at an angle less than ninety degrees from the horizontal position, whereby when the arm is in the horizontal position, the central channel of the ball valve is in parallel alignment with the vertical axis of the tubular member and the ball valve is set and maintained in the open position, and when the arm is in the raised position at an angle less than ninety degrees from the horizontal, the upward movement of the arm actuates the linkage assembly to rotate the ball valve such that its central channel is aligned parallel to the horizontal axis, to set and maintain the ball valve in the closed position.
