Patent number: 6302335Abstract: A lawn sprinkler system is provided for receiving fluid from a fluid source and distributing the fluid over an area. The lawn sprinkler system includes multiple lawn sprinklers for distributing fluid over corresponding portions of the area. Stake assemblies are provided for supporting the lawn sprinklers above a supporting surface. Each stake assembly includes an input operatively connected to the fluid source, a first output for providing fluid to the corresponding sprinkler, and a second output. A conduit interconnects the second output of one of the stake assemblies to the input of an adjacent stake assembly to connect the adjacent stake assembly to the fluid source.Type: GrantFiled: September 22, 2000Date of Patent: October 16, 2001Inventors: Timothy G. Ormiston, Sharyn A. Ormiston

Patent number: 6257501Abstract: A mister and an electric fan combination is mounted upon a vertical stand. The mister has a housing arranged to define a curvature that is concentric with a rotational center of rotary fan blades and with the central back of the fan. The housing is attached to the fan guard grill. The mister has a flexible hose extending from a junction with the housing to a location distal from the housing to convey pressurized fluid from a source. The electric fan is pivotally connected on diametrically opposite sides to a connection structure, which is raised by a pole from a base structure.Type: GrantFiled: September 5, 2000Date of Patent: July 10, 2001Assignee: Atico International USA, Inc.Inventors: Kenneth Roach, Don Lee, Cobol Shu

Patent number: 6247658Abstract: A stowable device for washing the underside and wheel well regions of a vehicle includes a base member joined at one end to a handle member such that the angle between the members can vary. A water jet disposed adjacent the distal end of the base member has a slit-like outlet. A length of flexible tubing couples the water jet to a trigger handle and waterjet valve located on the free end of the handle member. A source of water is coupled to the trigger handle, and passes through the flexible tubing and out the waterjet when the user presses the water jet valve. At least one non-swivelling wheel assembly is attached to the base member. The ratio between the length of the base member and the width of the wheel assembly preferably exceeds about 20:1 to promote maneuverability of the device.Type: GrantFiled: April 14, 2000Date of Patent: June 19, 2001Inventor: John Bakas
