Abstract: Described is a drain cleaner assembly, including: a clamp knob having a central cavity therein for accommodating a drain snake; a spout having a central cavity therein for accommodating the drain snake; the spout having at least one gripper cavity therein; at least one gripper disposed in the at least one gripper cavity; the clamp knob and the spout being attached to one another and also being displaceable with respect to one another to achieve at least two orientations, the at least two orientations comprising: a first orientation wherein the clamp knob contacts the at least one gripper and forces the at least one gripper into securing contact with the drain snake; and a second orientation wherein the clamp knob permits the at least one gripper to transition within the at least one gripper cavity to be out of securing contact with the drain snake. Other aspects are described and claimed.

Abstract: An apparatus and method for protecting against electrocution hazards that arise when an appliance is electrically connected to a miswired single-phase AC electrical source which includes an energized ground lead are described. The apparatus includes one or more sensors that detect electrical energy in the ground lead combined with a miswiring condition in the hot and common leads. A tester embodiment is also illustrated. The method includes the steps of detecting if the putative ground of the electrical source is energized and whether the hot and common leads are reversed.
Abstract: A drain cleaning apparatus which feeds a drain cleaning snake from a rotating drum through a flexible guide tube and a manually operable cable feed device is provided at the outer end of the guide tube for selectively axially advancing or retracting the snake relative to the cable drum during rotation of the drum. The inner end of the guide tube is supported directly on the cable drum with a bearing for relative rotation between the cable drum and the guide tube. The cable feed device includes a stop protruding from its housing which is positioned for engaging an actuating lever to thereby limit the pivotal extent of the levers displacement away from the housing in order to prevent accidental dislodgement of the drive actuator which is engaged by the lever to operate the cable feed device.
