Abstract: The present invention relates to an improved level wind arm for a winch drum assembly, and a winch drum assembly incorporating such a level wind arm. The level wind arm includes a cross member adapted to bias against an outwardly extending portion of rope, the cross member being concave so that more force is required for the rope spindle associated with the cross member to “climb” the slope of the cross member, causing a momentary pause in motion of the spindle after it reaches the end of wind stroke. This momentary pause allows for rope being wound onto the drum to rise up the end wall of the drum to create a new layer which is aligned and consistent with the layer below, without causing gaps in the rope or other circumstances which could lead to the rope accumulating at any one point, or becoming tangled. The present invention also includes means of ensuring that tension is maintained in the rope, and that the rope does not jump off the reel and, for example, into the clutch mechanism.

The generator generates electrical power that can be, e.g., used to charge a battery, rotate a reel, or to directly control a fluid flow control valve associated with the fluid flow. In the garden hose context, neither AC power nor frequent battery replacement is required because power from the generator can recharge the battery powering the valve and the reel.

Abstract: A device for moving the hose of an automatic pool cleaner in and out of a swimming pool using water power. The device includes a rotatable hose reel in communication with a pool. The hose reel is connected to a rotatable water wheel having vertically-oriented blades disposed around its circumference. During storage, the hose of the pool cleaner is wrapped around the hose reel. To move the hose from the storage position into the pool, a stream of water from a blow out jet nozzle tangentially swipes the coiled hose and is directed at a cleaner head attached to the hose. The water flushes the cleaner head into the pool and rotates the hose reel in a first direction, causing the hose to unwind and travel into the pool.
