  • Windup-hose irrigating apparatus
    Patent number: 4538761
    Abstract: An irrigating apparatus whose hose drum is propelled by water power to take up the hose. A hose guide is movable back and forth across the drum to deposit the hose in layers thereon and the hose guide is coupled to a threaded spindle on which a nut rides. A link connects this nut to a valve which throttles the flow to the water-power motor for the drum to progressively decrease the angular velocity of the drum as the hose is taken up.
