Abstract: A water ski tow rope retrieval and payout system is disclosed. The system includes a reel having a quantity of tow rope wound therearound. The reel is powered by an electric motor through a drive shaft which is also coupled to an electrically controlled brake or clutch. The brake or clutch acts to keep the drive shaft, and thus the reel, from rotating freely when the electric motor is not being used to pay out or retrieve tow rope. An embodiment of the water ski tow rope retrieval and payout system having radio remote control is also disclosed.

Abstract: An apparatus for electric wiring, including a housing having a folding stand and a handle, a reel including a flexible tape, a rolling ball-equipped tape leader detachably connected to the lead end of the flexible tape outside the housing, a motor drive controlled to let off/take up the flexible tape, permitting the lead end of the flexible tape to be moved between the inlet of an electric conduit to the outlet thereof to carry an electric wire through the electric conduit, and photo detectors adapted for detecting the movement of the flexible tape so as to automatically cut off power supply from the motor drive when the flexible tape is fully extended out or retracted.

Abstract: An improved reeling device including a reel driven by an electric motor. The device further includes a hose having first and second ends and two electric conductors running along the entire length of the hose between the first and second ends of the hose. The hose is wound on the reel. The first end of the hose is connectable to a tool, and the second end of the hose is connected to the reeling device. The conductors at the second end of the hose extend from the hose such that one of the conductors is in communication with the motor and the other conductor is attached to a part of the reel device. A switch is connected to the conductors at a proximity of the first end of the hose and the switch is arranged to complete an electrical circuit.
