Abstract
A power feed device for use with a hand held sewer and drain cleaning machine having an elongate, coiled cable and a rotating means for rotating the cable, the power feed device comprising two rollers rotatably mounted on housings, the housings being rotatably mounted within a body of the device, biasing means for biasing one of the housings and thereby one of the rollers toward the cable, cable centering means for centering the cable between the two rollers, means for rotating the roller housings from a "NEUTRAL" position wherein the axes of rotation of the rollers are parallel to the axis of rotation of the cable such that when the cable is rotated in the first rotational direction the cable is not moved along its elongate axis relative to the rollers, to a "FORWARD" position wherein the axes of rotation of the rollers are skewed to the axis of rotation of the cable and such that when the cable is rotated in the first rotational direction the cable moves along its elongate axis in a first direction, or to a "REVERSE" position wherein the axes of rotation of the rollers are skewed to the axis of rotation of the cable such that when the cable is rotated in the first rotational dire…
