Abstract: An apparatus for routing a passageway in a conduit includes an elongate cable for direction into a conduit passageway. A cable supply drum contains a supply of the cable and is rotatable about an axis, there being a length of the cable projecting to outwardly of the drum. A motor selectively imparts rotation to the drum about the axis. The cable and drum are configured such that the projecting length of cable rotates about its length as an incident of the drum being rotated about its axis. A brake is provided for stopping rotation of the drum and thereby rotation of the projecting length of cable so as to prevent torquing of the projecting length of cable as when the projecting length of cable is prevented by freely rotating by an obstruction encountered in a conduit passageway.

Abstract: A rotary drain and sewer cleaning apparatus includes a flexible elongate cable insertable into a line. An end of the elongate cable is attached in a drum and a portion of the elongate cable is wound in the drum. A motor rotates the drum. A power supply and switch selectively provide current to the motor causing the motor to rotate. A circuit includes a sensor for measuring a motor drive torque as the drum rotates and generating a torque signal representing motor drive torque level. An indicator is controlled by the torque signal and indicates the torque level.
