Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
194 words
A winding apparatus for applying two stages of pulling force to a rope or line or the like comprising: a. a gear housing adapted to be secured to a boat deck; b. a center post on said housing having a longitudinal passage extending therethrough; c. a tubular shaft extending through said center post passage; d. a drum secured to the upper end of said tubular shaft for rotation therewith; e. a ring gear carried in the lower end of said tubular shaft; f. a spindle rotatably mounted in said tubular shaft and extending therethrough; g. a low torque gear train operably connected to said spindle and including gear means for rotating said ring gear when said spindle is rotated in one direction; h. a high torque gear train operably connected to said spindle for rotating said ring gear when said spindle is rotated in the opposite direction; and i. clutch means mounted with said high and low torque gear trains to render said high torque gear train inoperable when said spindle is rotated in said one direction and to render said low torque gear train inoperable when spindle is rotated in said opposite direction.
Claim 2
Dependent Claim
194 words
A winding apparatus for applying two stages of pulling force to a rope or line or the like comprising: a. a gear housing adapted to be secured to a boat deck; b. a center post on said housing having a longitudinal passage extending therethrough; c. a tubular shaft extending through said center post passage; d. a drum secured to the upper end of said tubular shaft for rotation therewith; e. a ring gear carried in the lower end of said tubular shaft; f. a spindle rotatably mounted in said tubular shaft and extending therethrough; g. a low torque gear train operably connected to said spindle and including gear means for rotating said ring gear when said spindle is rotated in one direction; h. a high torque gear train operably connected to said spindle for rotating said ring gear when said spindle is rotated in the opposite direction; and i. clutch means mounted with said high and low torque gear trains to render said high torque gear train inoperable when said spindle is rotated in said one direction and to render said low torque gear train inoperable when spindle is rotated in said opposite direction.
Claim 3
Dependent Claim
48 words
The invention of claim 1 wherein said housing includes a lower case having a bottom and a cylindrical upstanding side with said center post mounted on an annular skirt and having seal means between said annular skirt and said side wall for excluding moisture from said gear housing.
Claim 4
Dependent Claim
54 words
The invention of claim 1 wherein said drum is provided with a cap which surrounds the upper end of said spindle and has a first seal means between said drum and said cap and a second seal means between said cap and the upper end of said spindle for excluding water or moisture therefrom.
Claim 5
Dependent Claim
39 words
The invention of claim 3 including a third seal means between the lower end of said drum and the lower end of said center post to provide a moisture barrier to exclude moisture from said drum and center post.
Claim 6
Dependent Claim
108 words
The invention of claim 1 wherein said low torque gear train includes: a. a first gear means carried by said spindle; b. a cam clutch means mounted on said spindle, said cam clutch means having means for connecting said first gear means to said spindle for rotation therewith when said spindle is rotated in a first direction and means for disconnecting said first gear means from said spindle when said spindle is rotated in the opposite direction; and c. a ring gear drive gear engaged by said first gear means and said ring gear for rotating said ring gear when said spindle is rotated in said first direction.
Claim 7
Dependent Claim
67 words
The invention of claim 1 wherein said high torque gear train includes: a. a spindle drive gear carried by said spindle and rotatable therewith; b. an idler gear carried in said gear housing and engaged with said spindle drive gear; c. a cam clutch gear operably connected to said idler gear and said ring gear drive gear for rotating said ring gear when said spindle is rotated.
