Patent number: 9809962Abstract: A recreational vehicle holding tank drain clearing assembly includes a tube having a first end, a second end and a perimeter wall. A first mating member is attached to the first and engages a first connecting member of a holding tank drain. A second mating member is attached to the second end and engages a drainage conduit. A cap is removably coupled to the second end of the tube. An air inlet is mounted on the cap and is fluidly coupled to the tube. A closure is mounted on the tube and is positioned in a first position preventing fluid movement through the tube or in a second position allowing fluid movement through the tube. Air is injected into the tube through the air inlet such that the air removes material trapped in the holding tank drain to increase flow from the holding tank through the holding tank drain.Type: GrantFiled: July 25, 2016Date of Patent: November 7, 2017Inventor: Randy Gehring

Patent number: 8286275Abstract: Drain clean-out assemblies that can be used to drain the contents of a drain line prior to removing a clean-out plug mounted to the assembly or to which the assembly is mounted. The drain clean-out assembly includes clean-out plug and a device for selectively preventing and permitting drainage of a fluid through the assembly. The assembly may include a housing having oppositely-disposed first and second ends and a drain between the first and second ends and in fluidic communication with an interior of the housing, wherein the first end of the housing is configured to attach to a drain line, the preventing and permitting device is within the housing, and the clean-out plug is removably attached to the housing. Alternatively, the preventing and permitting device may be permanently mounted to the clean-out plug.Type: GrantFiled: August 21, 2008Date of Patent: October 16, 2012Inventor: Brian Michael Kipp

Patent number: 6363566Abstract: A blockage clearing apparatus to clear blockages in both drain valves and in pipes. A cylindrical housing holds a piston connected to a cylindrical rod. The piston moves within the cylindrical housing in response to pressure placed on the piston either manually by an operator or by hydraulic or pneumatic power. As the piston moves in the cylindrical housing, the rod connected to the piston moves back and forth in response to the motion of the piston. The blockage clearing apparatus is mounted to a drain valve or to an opening in a pipe. When operated by pneumatic power, valves, manual or solenoid controlled, will control the flow of air in and out of ports in the cylindrical housing, creating a pressure differential within the housing to actuate the motion of the piston, hence, of the rod. The rod will extend from the housing through an open drain valve and into the pipe that is in fluid communication with the drain valve.Type: GrantFiled: December 18, 1999Date of Patent: April 2, 2002Inventor: Michael Collins

Patent number: 6206021Abstract: A sleeve valve comprises a sleeve and a gate. The sleeve includes an intake, a discharge nozzle section, and a clean-out section. The discharge nozzle section includes a plurality of nozzles. The sleeve is adapted for fluid flow from the intake through a fluid passage and out the nozzles. The clean-out section includes at least one access port. The gate is adapted for sliding within the sleeve in sliding sealing engagement with the interior surface of the sleeve between closed, throttling, open, and clean positions. The gate and sleeve are configured so that the gate, when in the closed position, prevents fluid within the fluid passage from flowing out the nozzles and the access port. The gate and sleeve, when in the throttling position, permits fluid within the fluid passage to flow out some of the nozzles but prevents fluid within the fluid passage from flowing out the access port of the clean-out section and others of the nozzles.Type: GrantFiled: March 1, 2000Date of Patent: March 27, 2001Inventors: Thomas A. Hartman, Brian T. Hartman

Patent number: 6182677Abstract: A cleanout fitting for air conditioner evaporator drains facilitates the mechanical cleanout and hydraulic flushing of the entire drain line from an air conditioner evaporator unit, or air handler. The present fitting essentially comprises an asymmetric T configuration, with a shutoff valve in one side of the crossmember of the T and a removable cap in the opposite end of the crossmember. The fitting is normally configured with the cap in place to block drainage therefrom, and with the valve open to permit flow from the evaporator pan through that crossmember side and out the stem of the T to an appropriate drain system. When the line becomes blocked and causes water in the evaporator pan to back up, the plug is removed, allowing a mechanical cleanout tool (snake, etc.) to be passed straight through the crossmember of the T and its open valve, to the evaporator pan.Type: GrantFiled: January 6, 2000Date of Patent: February 6, 2001Inventor: James Pignataro
