    Abstract: An in line mechanical timing valve is disclosed. The valve has an inlet capable of being coupled to a water source and an outlet. A valve housing is fluidly coupled to the inlet and the outlet to control water flow between the inlet and the outlet. A bisecting cylinder is installed perpendicular to the inlet and outlet. The bisecting cylinder has a central axis and a diaphragm which has an open position allowing water flow to the outlet and a closed position preventing water flow to the outlet. A dial knob has an extended position and a retracted position. The dial knob is rotatable about the central axis of the bisecting cylinder when in the retracted position. A timing mechanism has a windup shaft parallel to the central axis of the bisecting cylinder. One end of the windup shaft has one end coupled to the dial knob which allows the timing mechanism to be set by the dial knob.

  • Patent number: 6644625
    Abstract: A pistol grip hose nozzle is disclosed which allows proportional water control in accordance with the position of a rotatable valve. The hose nozzle has a handgrip section with an inlet water passage and an outlet section with an outlet water passage. One end of the handgrip section is connectable with a hose. The other end of the inlet water passage ends in a valve seat with an aperture. The valve seat contains a valve having a flow control cylinder. The flow control cylinder has a non-circular opening which when aligned with the aperture allows water to flow to the outlet water passage. The flow control cylinder is attached to a control knob which allows a user to grip the hand grip portion and rotate the control knob and the flow control cylinder to vary the water flow. The non-circular opening allows the amount of water flow to the outlet water passage to be linearly proportional to the rotational position of the control knob.

  • Patent number: 6604697
    Abstract: A self propelled sprinkler is disclosed. The sprinkler has a support body with a drive unit which drives two rear wheels. The drive unit is powered by water pressure supplied through a hose which is coupled to the drive unit via a hose coupler. The drive unit has a cylindrical drive chamber with circular impeller in fluid communication with the hose coupler. The impeller is rotated by the water pressure and is mechanically connected to a lateral shaft. The shaft is connected to the rear wheels. Reduction gearing from the impeller to the shaft governs the speed of the sprinkler. The reduction gearing is achieved through a series of sun gears, carrier disks and planet gears. The drive unit also has an outlet which has a socket which allows the exit of the pressurized water. The socket allows the insertion of any variety of sprinkler heads. Thus, the sprinkler allows a variety of water distribution patterns. The sprinkler is propelled by water pressure rotating the impeller and eventually the rear wheels.

  • Patent number: 6601779
    Abstract: A rotating bearing assembly for a sprinkler coupled to a pipe segment is disclosed. The bearing assembly has a stem which permits fluid flow. The stem has a bottom open end with a collar and a top open end which is connected to a cap. The cap allows connection to a sprinkler head which rotates from water pressure through the pipe segment. The stem conduit rotates in relation to a sleeve which is frictionally fitted within the pipe segment. A plurality of washers is located between the collar and the bottom of the sleeve to provide a water seal under high pressure conditions. Another group of washers is located between the top of the sleeve and the cap to provide additional sealing under low pressure conditions.

  • Patent number: 6547166
    Abstract: A pattern adjustable flow nozzle which maintains a constant fluid flow rate is disclosed. The flow nozzle is comprised of two parts, an inner tubular body and an outer tubular sleeve, rotatable one on the other. Orifices are disposed on the output end of the tubular body and tubular sleeve, and the superposition of those orifices in various rotational alignments determines the throw and pattern of the ejected fluid. Flow cavities on the inner tubular body allow for a constant rate of fluid flow over the range of orifice superpositions.
