Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIGS. 1 to 4 thereof, a new and improved outboard motor flushing apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
More specifically, the outboard flushing apparatus 10 essentially comprises a first resilient circular head member 11 formed with an internal face 11a coaxially aligned with a companion internal face of a second resilient head member 12 to overlie a fluid input opening portion of an outboard motor drive assembly "O". The outboard motor drive assembly is conventionally positioned extending rearwardly of a transom "T" of an associated boat. The first and second head members 11 and 12 respectively are secured in a coaxially aligned relationship utilizing a resilient "U" shaped bracket 13 normally biasing the confronting surfaces of the head members together. A flexible fluid conduit 14 is coaxially aligned with the second head member 12 to direct pressurized fresh water flow 15 through the conduit and subsequently through the second head member 12 and direct such fresh water interiorly of the outboard drive assembly "O".
An elongate, rigid shaft 16 is formed with a planar forward terminal end surface 16a aligned generally orthogonally relative to the elongate rigid shaft 16 and includes a clamp assembly 17 mounted thereon. FIG. 4 illustrates details of the clamp assembly, wherein a semi-cylindrical clamp member 18 includes diametrically opposed and aligned leg members 19 arranged to overlie the planar surface 16a. Apertures 20 are formed orthogonally through the leg members 19 to receive threaded bolt members 21 therethrough. The threaded bolt members are thereafter received within complementary threaded blind bores 22 aligned with the apertures 20 to secure the semi-cylindrical clamp member 18 and leg members 19 in a confronting relationship relative to the planar forward surface 16a. The semi-cylindrical clamp member 18 is defined by a radius somewhat less than that defined by the diameter or width of the resilient "U" shaped bracket 13 to enable secure clamping of the bracket 13 in an adjustable relationship relative to the clamp assembly 17.
In this manner, an individual may position himself remotely from the outboard drive assembly "O" and by positioning within the boat or from a position adjacent the outboard drive assembly "O" permitting the first and second head members 11 and 12 to be secured to the outboard drive assembly.
As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly, no further discussion relative to the manner of usage and operation of the instant invention shall be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
