Abstract
A hand operated drain cleaner includes a manually operated rotatable drum and an elongated flexible cable at least partially held in the drum. A portion of the cable extending from the drum has a cable axis, and rotation of the drum rotates the cable portion about the cable axis. A handle is adapted to rotatably support the drum. The handle includes a barrel portion and a handle portion. A feed control device includes a housing having a feed passage axially therethrough for receiving the cable and a trigger for moving the feed control device between a non-actuating position and an actuating position. In the actuating position, a feed control device is pivoted relative to the handle such that the driving mechanism engages the cable thereby inducing axial movement of the cable via rotation of the drum. A locking mechanism is opera operably associated with the feed control device.
