Patent ID: 7645346

Claim:
A cleaning apparatus to be assembled in a conduit for cleaning a pipeline by increasing the flow rate of pipeline fluid, comprising: (A) a platform of a dimension sufficient to be inserted through an opening in said pipeline, said platform comprising one or more portions; (B) a fluid interrupter comprising one or more parts to provide a surface to contact fluid flow thereby interrupt fluid flow, the fluid interrupter constructed and arranged to be attached to the platform; a downstream side of the fluid interrupter being supported by members connected to the platform to dispose the fluid interrupter against fluid flow; (C) runners attached to the underside of the platform to contact an inner diameter of the pipeline; whereby the supported fluid interrupter, underside of the platform, and the runners form a channel through which fluid flows downstream; and (D) a device located at the downstream end of the said channel, the device arranged to constrict the volume of the fluid directed through the channel such that the flow rate is increased to move solid waste in the pipeline.
