Abstract

Abstract A power system comprising a generator mounted on the propulsion unit of an outboard motor through an interposed adaptor which exposes the drive connection between the generator and propulsion unit to allow access thereto for employment of the drive mechanism for the driving of accessories other than the outboard motor. Clutch means selectively couple the drive means of the generator and the driven means of the propulsion unit for a selective operation of the mounted generator independently of the propulsion unit.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 68 words
A power system comprising a power driven generator, a propulsion unit incorporating a driven shaft, an adaptor mounting said generator on said propulsion unit, said generator including a drive shaft, and clutch means selectively coupling said generator drive shaft and said propulsion unit driven shaft upon attainment, by said generator drive shaft, of a predetermined rotational speed for a direct driving of the propulsion unit by the generator.
Claim 2
Dependent Claim 68 words
A power system comprising a power driven generator, a propulsion unit incorporating a driven shaft, an adaptor mounting said generator on said propulsion unit, said generator including a drive shaft, and clutch means selectively coupling said generator drive shaft and said propulsion unit driven shaft upon attainment, by said generator drive shaft, of a predetermined rotational speed for a direct driving of the propulsion unit by the generator.
Claim 3
Dependent Claim 40 words
A system of claim 1 wherein said clutch means comprises a two-section centrifugal clutch, one of said clutch sections being secured to the generator shaft and the second of said clutch sections being secured to the propulsion unit driven shaft.
Claim 4
Dependent Claim 19 words
The system of claim 2 wherein said propulsion unit includes auxiliary power takeoff means affixed to said driven shaft.
Claim 5
Dependent Claim 65 words
The system of claim 3 wherein said propulsion unit comprises a generally vertically orientated outboard motor leg including said driven shaft, a housing surrounding said driven shaft, propeller means mounted on the lower end of said shaft at the lower end of said housing, the second of said clutch sections engaging the upper end of the driven shaft at the upper end of the housing.
Claim 6
Dependent Claim 65 words
The system of claim 4 wherein said adaptor includes an upper plate engaged with the generator outwardly spaced from the generator drive shaft, a lower plate fixed to the propulsion unit housing and rigid spaced braces extending between said plates and orientating the plates, and thus the generator and propulsion unit, in fixed relation to each other exposing the clutch assemblies and auxiliary power takeoff.
Claim 7
Dependent Claim 80 words
The system of claim 1 wherein said adaptor includes an upper plate, mounting means engaging said upper plate with the generator outwardly spaced from the generator drive shaft, a lower plate, mounting means fixing the lower plate to the propulsion unit, and rigid spaced braces extending between and orientating said plates, and thus the generator and propulsion unit, in fixed spaced relation to each other, said clutch means being exposed within said adaptor between the upper and lower plates thereof.
Claim 8
Dependent Claim 68 words
A power system comprising a power driven generator including a projecting drive shaft, a propulsion unit incorporating a projecting driven shaft, means selectively coupling said shafts for a driving of the driven shaft by the drive shaft, and an adaptor rigidly joining said generator and said propulsion unit in fixed spaced relation to each other, said adaptor having a framework exposing the selectively coupled shafts for access thereto.
Claim 9
Dependent Claim 68 words
A power system comprising a power driven generator including a projecting drive shaft, a propulsion unit incorporating a projecting driven shaft, means selectively coupling said shafts for a driving of the driven shaft by the drive shaft, and an adaptor rigidly joining said generator and said propulsion unit in fixed spaced relation to each other, said adaptor having a framework exposing the selectively coupled shafts for access thereto.
Claim 10
Dependent Claim 20 words
The system of claim 7 including auxiliary power takeoff means mounted on at least one of said selectively coupled shafts.
Claim 11
Dependent Claim 44 words
The system of claim 7 wherein said adaptor includes an annular flat upper plate positionable in surrounding relation to the generator shaft, an annular flat lower plate positioned in surrounding relation to said propulsion unit shaft, and peripherally spaced braces rigidly interconnecting said plates.
Claim 12
Dependent Claim 22 words
The system of claim 9 including radially outward projecting mounting lugs at peripherally spaced points about the upper plate of the adaptor.
