Abstract: A mechanism for advancing a rotating cylindrical member which has a frame and opening to accept a cylindrical member extending therethrough in a first line, and an advancing roller for engagement with a cylindrical member extending through the frame opening. The advancing roller is mounted to the frame for rotation about a first axis that is transverse to the first line to thereby cause a rotating cylindrical member in the frame opening that encounters the advancing roller to be advanced along the first line substantially parallel to the frame opening axis. The advancing roller is preferably carried by a mounting block which is mounted to the frame movably between first and second positions. By moving the mounting block between its first and second position, the advancing roller is moved towards and away from the frame opening axis to thereby vary the distance of the advancing roller from the frame opening axis to accommodate different diameters of cylindrical members to be advanced by the mechanism.

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.
