Abstract
An adaptor for use with dockside pumps to facilitate pump out of sewage holding tanks is constructed so that it readily accommodates both of the two most common fittings for dockside pumps, an elastomeric material right circular cone frustrum, and a cam actuated fitting having a number of curved locking surface locking cams. The adaptor is a tubular body of rigid material having first and second ends with a concentric bore. An interior surface of the first end defines a cone frustrum cooperable with the dockside pump cone frustrum fitting, and the exterior surface of the first end is a cylindrical surface with a semi-toroidal recess at a central axial portion, which recess cooperates with the curved surfaces of the locking cams. The second end of the adaptor has external threads that fit one of three common sizes of boat deck fitting internal threads (e.g. a nominal diameter of 11/4 inches and 111/2 threads per inch), and an annular flexible sealing ring can be provided between the threads and a collar of the adaptor.
