Abstract

A water ski line retractor which comprises a reverse polarity motor which functions a drive pulley through a worm gear drive. The drive pulley is connected by a belt to a spool pulley which is loosely mounted upon a shaft. A line winding spool fixedly mounts upon the same shaft in side by side juxtaposition to the spool pulley and a clutch is interposed between the line spool and the spool pulley in a manner to permit relative movement of the line spool and the spool pulley. A two way switch controls motor operation in clockwise and counterclockwise direction for automatic line extending the line retrieving purposes.

Claims

1. In a water ski line retractor to vary the distance between the tow end of a ski line and a boat, the combination of

A. a frame;

B. a motor mounted upon the frame,

C. a spool shaft rotatably mounted upon the frame in spaced relationship from the motor,

3. The water ski line retractor of claim 1 including second friction clutch means interposed between said spool pulley and said frame, said second friction clutch means comprising a friction washer overfitting the spool shaft, a friction clutch disk interposed between the friction washer and the spool pulley and adjustment means to urge the friction clutch disk into frictional engagement with the spool pulley.

5. The water ski line retractor of claim 3 wherein the adjustment means comprises means to urge the second clutch disk into frictional engagement with the spool to rotate the spool when the motor is energized.

2. a spool pulley mounted on said spool shaft and being rotatable by said motor for spool rotating purposes;

2. said spool pulley including means to permit the spool shaft to rotate relative to said spool pulley;

D. a spool mounted upon the spool shaft,

1. said water ski line winding upon and unwinding from the spool in response to operation of the motor,

2. said spool being connected to the spool shaft by means to prevent rotation of the spool relative to the spool shaft; and

E. first friction clutch means interposed between the spool pulley and the spool to permit the spool to slip relative to the spool pulley upon the application of a drag weight to the water ski line.

4. The water ski line retractor of claim 2 wherein the first friction clutch means comprises a second friction clutch disk overfitting the spool shaft, the second clutch disc being interposed between the spool pulley and the spool.
