ABSTRACT:
Drain Cleaning Apparatus for rotating a drain cleaning snake comprises a frame and housing assembly supporting an axially displaceable clutch actuating shaft which supports a first clutch actuator for rotation relative thereto and axial displacement therewith. A second clutch actuator is coaxial with the first actuator and supported in the housing for rotation relative thereto. A radially expandable and contractible clutch is captured between the two clutch actuators for engaging and disengaging a drain cleaning snake extending therethrough. A motor drives the first clutch actuator through a transmission pulley and belt arrangement in which the belt is axially slidable relative to a pulley in response to axial displacement of the first clutch actuator relative to the second clutch actuator. The clutch and second clutch actuator are in a shroud at one end of the housing, and the axial position of the second actuator relative to the first actuator is adjustable. The shroud is mounted on the flame to facilitate removal and replacement of the clutch and access to the second clutch actuator, and a housing portion adjacent the shroud is removable to provide access to the transmission components.
