Abstract: A pipe such as a sewer line or the like is cleaned by advancement therethrough of a rigid tubular member having at its lead end a nozzle for ejecting a stream of water to dislodge debris, etc., followed by a series of rotary cutters and pushes for removing more stubborn foreign materials.

Abstract: The disclosure is of a method and means for applying a flowable coating material, such as relining, to a tubular stack; e.g. chimney, flue or the like, by means of a distributor moved upwardly into the stack while supplying coating material to an upper surface of the distributor which is configured to cause the material to flow outwardly to the wall to adhere thereto. The apparatus includes selectively added extensions for moving the distributor incrementally through the length of stacks of considerable height, preferably by means of power-operated means; e.g., a fluid-pressure device.
