Sewage dump system for RV, marine and other mobile vehicles

Abstract

The sewage dump system of this invention comprises an elongated housing adapted for support on a mobile vehicle, the housing having an elongated sewage hose storage compartment having a height slightly greater than the diameter of a storage hose and communicating at its open end with an adjoining space configured to contain a hose outlet fitting on the outlet end of the sewage hose, the storage hose being folded intermediate its ends for reception in the hose storage compartment for guidance therein between said folded condition within the compartment and an extended position with the hose fitting communicating with a sewage dump site. In one embodiment, a plurality of spaced rollers having concave peripheries are spaced apart along one longitudinal side of the storage compartment to facilitate guiding the storage hose during extension and retraction. In a second embodiment a yoke member having guide rollers on its spaced ends is connected to a line extending retractably from a rotary power source for movement between a position retracted within the hose compartment with the folded sewage hose and an extended position at the adjoining space for extending the sewage hose to a sewage dump site.

1 . A sewage dump system for RV and other mobile vehicles having sewage waste systems, the sewage dump system comprising: 
 a) an elongated housing adapted for support on a mobile vehicle,    b) the housing including an elongated sewage hose storage compartment defining a space having a height slightly greater than the diameter of a small diameter sewage hose and having a closed end and an open end, and    c) an adjoining space in the housing communicating with the open end of the sewage hose storage compartment and configured to removably contain a hose outlet fitting on the outlet end of a sewage hose configured for communication with a sewage dump site.    
   
   
       2 . The sewage dump system of  claim 1  including a plurality of hose guides spaced apart in said storage compartment and configured to guide a folded sewage hose during extension from and retraction into said storage compartment.  
   
   
       3 . The sewage dump system of  claim 2  wherein the hose guides comprise rollers having concave peripheries and spaced apart along one longitudinal side of the storage compartment.  
   
   
       4 . The sewage dump system of  claim 2  wherein the hose guides include a yoke member having spaced ends, a guide roller on each of the spaced ends of the yoke member configured to engage a small diameter sewage hose, and drive means engaging the yoke member for moving the latter between an extended position adjacent said adjoining space, with a sewage hose extended from the storage compartment to a sewage dump site, and a retracted position adjacent the closed end of the hose storage compartment with the sewage hose folded in said storage compartment.  
   
   
       5 . The sewage dump system of  claim 4  wherein the hose guides comprise rollers having concave peripheries.  
   
   
       6 . The sewage dump system of  claim 1  including 
 a) an elongated sewage hose of small diameter, and    b) a macerator having an outlet end communicating with the end of the sewage hose opposite the hose outlet fitting and an inlet end communicating with the sewage waste system of the vehicle.
