Abstract
Abstract An improved apparatus for winding a water-ski rope on a reel in a short period of time by utilizing a winding device containing a spring which becomes wound up as the rope is progressively unwound from the reel. When the load is removed from the end of the rope, the spring returns to its original non-stress condition causing the rope to be wound up on the reel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
An apparatus for unwinding and winding a water-ski line comprising a stationary shaft, a reel adapted to contain a supply of line rotatably mounted on said shaft, a rotary drum mounted for rotation about said shaft, means for transferring the rotation of the reel to the drum, said transferring means comprising a stationary gear fixed to the stationary shaft, internal gear-like teeth provided on the reel, and planetary gears providing gear-meshing communication between said internal gear-like teeth and the stationary gear, said planetary gears being connected by shaft means to the rotary drum, a spring housed by said drum, said spring being attached to the stationary shaft and the drum such that upon unwinding the line from the reel, the spring is converted from a relaxed state to a compressed state and upon the winding of the line on the reel, the spring is returned to its relaxed state.
Claim 2
Independent Claim
149 words
An apparatus for unwinding and winding a water-ski line comprising a stationary shaft, a reel adapted to contain a supply of line rotatably mounted on said shaft, a rotary drum mounted for rotation about said shaft, means for transferring the rotation of the reel to the drum, said transferring means comprising a stationary gear fixed to the stationary shaft, internal gear-like teeth provided on the reel, and planetary gears providing gear-meshing communication between said internal gear-like teeth and the stationary gear, said planetary gears being connected by shaft means to the rotary drum, a spring housed by said drum, said spring being attached to the stationary shaft and the drum such that upon unwinding the line from the reel, the spring is converted from a relaxed state to a compressed state and upon the winding of the line on the reel, the spring is returned to its relaxed state.
Claim 3
Dependent Claim
31 words
The apparatus of claim 1, wherein the spring is a coiled spring with its inner end being attached to the stationary shaft and its outer end attached to the rotary drum.
Claim 4
Dependent Claim
20 words
The apparatus of claim 1, wherein the stationary shaft is supported by legs attached to the stern of a boat.
Claim 5
Dependent Claim
30 words
The apparatus of claim 3, wherein the legs are provided with a supporting bar which extends therefrom, said bar containing a ring for receiving the lines and guiding the same.
Claim 6
Dependent Claim
26 words
The apparatus of claim 1, wherein the reel, the stationary shaft, the rotary drum and the spring contained therein are concentrically disposed about the stationary shaft.
