  • Patent number: 7398954
    Abstract: A faucet adapter including an inlet assembly that includes a connecting portion configured for connection to a fluid source. A handle remote from the connecting portion is operably connected thereto such that actuation of the handle results in actuation of the connecting portion, independent of a fluid flow through the adapter.

  • Patent number: 6796515
    Abstract: A one touch valve for activating fluid flow between an inlet conduit and an outlet conduit is disclosed. The valve has a flow cylinder defining an inflow chamber in fluid communication with the inlet conduit and an outflow chamber in fluid communication with the outlet conduit. The flow cylinder includes an end plate and an intermediate plate having a center collar with an aperture. A flexible diaphragm is provided with a sealing surface in contact with the collar to create a seal. The diaphragm has an edge coupled to the intermediate plate and a small diameter hole providing fluid contact between the inflow chamber and an intermediate chamber which is defined by the intermediate plate of the flow cylinder. A plunger is placed on the diaphragm to create a seal with the opposite surface of the diaphragm from the sealing surface. A shaft has one end connected to the plunger and extends through the aperture of the diaphragm.

  • Patent number: 6604691
    Abstract: A irrigation device which has a sprinkler head and a wind driven device is disclosed. The device has a support frame which provides water to the sprinkler head. The support frame may include a number of pipes which supply water to the sprinkler head. The sprinkler head may have a rotating bearing and arms which are allow water to be sprayed out in various patterns. The force of the water also rotates the sprinkler head around the bearing. The support frame or sprinkler head also supports a wind driven device which may be audio, visual or both. For example, the support frame may suspend wind driven chimes.

  • 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: 6460701
    Abstract: A container device useful for selling nozzle heads for an irrigation system having various vertical sprinklers is disclosed. The container device has a tubular cylinder with an attachment end, an opposite open end and an exterior surface. The tubular cylinder is made of plastic and the attachment end is attached to a nozzle head. The nozzle head has a cylindrical base which mates with the attachment end of the tubular cylinder via a contact fit or screw-in threads. A debris screen for use with the nozzle head is fit within the tubular cylinder. The combination tubular cylinder and nozzle head allows inexpensive and simple packaging for the nozzle heads. The container device may be put on retail display with a gravity feed dispenser allowing dispensing of single containers for a consumer.

  • Patent number: 6283139
    Abstract: A remote controlled hose valve system for use with a water source and a hose having one end connectable to a fluid activated device and an opposite connector end is disclosed. The hose valve system includes a valve unit and a remote control unit. The valve unit has an inlet coupler connectable to the water source. The valve unit also has a hose coupler coupled to the opposite connector end of the hose. A conduit allows fluid flow between the inlet coupler and the hose coupler. A valve is located in the conduit and permits fluid flow in the conduit. An actuator which may be an electric motor is connected to the valve. A power source is provided for the actuator. A signal receiver is coupled to the power source and the actuator. The receiver allows power flow to the actuator to close or open the valve in response to a unique signal. The remote control unit includes a transmitter which sends a unique signal to open or close the valve.
