Abstract
Abstract A tank drain apparatus comprising an annular seal member (56) mounted on a tube (55) in turn mounted on a transparent drain hose (72), a sleeve (67) connecting tube (55) and hose (72) together, a portable ground stand assembly (15), and a unique leverage mechanism (10) operatively connecting sleeve (67) and stand (15) together, so that seal member (56) can be elevated to or lowered from the tank. A blade (61) in seal member (56) engages a drain valve while indicia (80, 83) on sleeve (67) indicates egree of angular rotation for tube (55) as against sleeve (67) to show the valve is opened or closed. Linkage mechanism (10) is adjustable in terms of its position on stand assembly (15). Also, the effort arm (36) of mechanism (10) can be locked in place by a clamping screw (52)-and-rod (53) arrangement mounted below the pivot point on the stand (15) for effort arm (36), to maintain seal member (56) in its elevated position against the tank's drain outlet.
