Abstract

Abstract A control assembly for a boat having a water jet propulsion system in which the jet is moved successively through a discharge conduit and a nozzle movably mounted on said conduit. A bucket is mounted on said nozzle and is movable with and with respect to said nozzle whereby said nozzle and bucket can be moved into different positions of adjustment to control the jet for thus controlling the steering, fore and aft movements, and the desired planing of the boat.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 173 words
A control assembly for a boat having a water jet propulsion power source, comprising a discharge conduit at the rear of said boat having an inlet operatively connected to said power source and an outlet, a nozzle having an inlet and outlet and extending around and projecting rearwardly of said conduit, said nozzle having a bearing socket formed in its inner face, said conduit having a longitudinally extending bearing race formed in its outer face, a bearing movably carried in said socket and race, a pivot pin on said nozzle swivelly connected to said conduit in diametrically opposed relation to said race, a bucket swingably mounted on said nozzle for movement between a reversing position in which it extends over said nozzle outlet to divert the jet flow from the power source generally forwardly from the nozzle and a retracted position in which said flow is permitted to move in a generally rearwardly direction through the nozzle outlet, and control means for moving said nozzle and bucket into the desired positions of adjustment.
Claim 2
Dependent Claim 173 words
A control assembly for a boat having a water jet propulsion power source, comprising a discharge conduit at the rear of said boat having an inlet operatively connected to said power source and an outlet, a nozzle having an inlet and outlet and extending around and projecting rearwardly of said conduit, said nozzle having a bearing socket formed in its inner face, said conduit having a longitudinally extending bearing race formed in its outer face, a bearing movably carried in said socket and race, a pivot pin on said nozzle swivelly connected to said conduit in diametrically opposed relation to said race, a bucket swingably mounted on said nozzle for movement between a reversing position in which it extends over said nozzle outlet to divert the jet flow from the power source generally forwardly from the nozzle and a retracted position in which said flow is permitted to move in a generally rearwardly direction through the nozzle outlet, and control means for moving said nozzle and bucket into the desired positions of adjustment.
Claim 3
Dependent Claim 36 words
The invention as set forth in claim 1 in which said nozzle has a longitudinally extending opening formed in its lower face, and a plurality of downwardly and forwardly angled vanes are mounted in said opening.
Claim 4
Dependent Claim 82 words
The invention as set forth in claim 1 in which said nozzle has a reversing section in lower face extending between the nozzle and conduit outlets, and open at its upper and lower ends for the passage of the jet flow therethrough when said bucket is in its reversing position, said section comprising a pair of side walls interconnected by downwardly and forwardly angled front and rear walls, and at least one downwardly and forwardly angled vane extending between said side walls.
Claim 5
Dependent Claim 43 words
The invention as set forth in claim 1 with the addition that said nozzle is provided with means engageable with said bucket when said bucket is in its reversing position for supporting said bucket in and limiting its movements into said reversing position.
Claim 6
Dependent Claim 69 words
The invention as set forth in claim 1 in which said bucket comprises a generally spherically shaped center section interconnecting a pair of side arms swingably connected to said nozzle, and said nozzle is provided with a reversing opening in its lower face and a slot disposed adjacent said opening for the reception of the lower edge of said center section when said bucket is in its reversing position.
