ABSTRACT:
A sewer cleaning machine includes a rotatable drum containing a coiled cable, a motor for rotating the drum, a balanced double cable guide rotatable with respect to the drum, a forward cable guide support which is pivotally mounted for tilting the drum forward to drain or remove the drum, an auxiliary handle for lifting the drum, and easily removed shrouding for the drum and motor. The drum is formed of sheet metal and includes a rearwardly extending annular wall which is driven by a roller coaxially attached to the motor shaft by an adjustable clutch. The clutch can be infinitely adjusted from total slip to total lock, and the motor stall torque is chosen to be less than the torque required to break the cable. A handle is bent to provide balance for the machine when it is moved and to support the machine when it is turned on its back.
