Patent number: 7246756Abstract: A water sprinkler for irrigating lawn and garden areas has two axes of movement, one transverse to the other. A barrel moves or oscillates on one horizontal axis to direct water spray from nozzles carried on the barrel across the length of the area, and the nozzle outlets also simultaneously move or oscillate on axes transverse to the barrel axis to spray water across the width of the area. As the nozzle outlets move or oscillate in the two transverse directions, the ground area is irrigated uniformly over time by application of water in a criss-cross pattern. The area sprayed can be surprisingly large compared with single-axis oscillators, or the area may be limited to a single row or a narrow rectangular area, by adjustment of the barrel and outlet movement and/or the water pressure.Type: GrantFiled: December 8, 2004Date of Patent: July 24, 2007Assignee: Orbit Irrigation Products, Inc.Inventor: Robert E.

Publication number: 20010019083Abstract: A rotary spray nozzle is provided in a housing which has one or more water inlets that direct the incoming water flow in a direction tangential to the inner walls of the housing. This creates a circular or swirling motion of water within the housing which in turn imparts a rotary motion to the nozzle. The liquid or water in the housing exits the housing through the rotating nozzle to thereby provide a rotary spray.Type: ApplicationFiled: February 20, 2001Publication date: September 6, 2001Inventor: Kipley Roydon Marks

Patent number: 6264118Abstract: A Strip irrigator comprising a body member fitted with an inlet for coupling to an irrigation water supply and an outlet nozzle of said body member, defining a longitudinal axis, a distribution member formed with a water engaging portion consisting of two ducts forming between them an essentially V-like shape with an intersection adjacent a lower end thereof, each duct ending at a deflection groove, and a support bracket pivotally supporting the distribution member to the body member. The arrangement being such that responsive to a water jet emitted from the outlet nozzle, the distribution member generates reactionary forces imparting it as a reciprocal rocking motion about a horizontal axis perpendicular to the longitudinal axis.Type: GrantFiled: December 21, 1999Date of Patent: July 24, 2001Assignee: Dan MamtirimInventors: Issak Kantor, Yoel Zur, Jonathan Bar-Or

Patent number: 6151748Abstract: A cleaning device for either carpeted or hard surfaces which utilizes pressurized cleaning fluid to clean the surface. The fluid nozzles are arranged on two or more heads which are in turn mounted on two or more arms. The arms rotate about a common axis causing the heads to move in a circular pattern. The heads rotate about their own central axis. The nozzles are angled relative to the surface being cleaned and preferably rotate towards the direction of the fluid jet. Preferably, at least two of the heads counter-rotate. Also preferably, the heads are arranged at somewhat different radial distances from the rotational axis of the arms so that their coverage patterns partially overlap. The combination of the counter rotation and the overlap provides an alternating, or beating, pattern to the angle of incidence of the fluid on the surface being cleaned.Type: GrantFiled: March 21, 2000Date of Patent: November 28, 2000Assignee: Environmental Cleaning Systems, Inc.Inventors: Robert E. Earhart, Jr., Kenneth F. Halls, Grant K. Halls

Patent number: 6129293Abstract: A rotary nozzle head has a rotor nozzle (50) through which flow can take place, two radially adjustable sheet metal deflector plates (30, 32) and a nozzle bearing (42), the axial position of which is adjustable. An axially adjustable functional element carrier (20) is formed at its downstream end as an actuation housing (22) and has the nozzle bearing (42) at the upstream end thereof. In addition, the functional element carrier (20) supports the sheet metal deflector plates (30, 32).Type: GrantFiled: January 27, 1998Date of Patent: October 10, 2000Inventor: Anton Jager

Patent number: 6123271Abstract: An apparatus for cleaning the interior of a vessel by ejecting a rotating stream of fluid. The apparatus features a gear train driven by the fluid received by an inlet, a stationary housing, a rotatable housing mounted for rotation on the stationary housing about a first axis, and a nozzle for ejecting the fluid, the nozzle being rotatably mounted on the rotatable housing so that the nozzle rotates about a second axis. A gear train is located between the inlet and the nozzle. In addition, a first gear, which, along with the gear train, drives rotation of the rotatable housing about the first axis, and a second gear, which drives the rotation of the nozzle housing about the second axis, are disposed on opposite sides of the second axis. A deflector deflects fluid running along the input drive shaft away from the gear train housing and a passage drains the deflected fluid to the surrounding environment.Type: GrantFiled: December 23, 1998Date of Patent: September 26, 2000Assignee: Gamajet Cleaning Systems, Inc.Inventors: Robert E. Delaney, Minh Quang Le, Bentley F. Gleeson, Warren F. Geiger

Patent number: 6085994Abstract: A multiple nozzle swivel assembly for mounting on a cable support stretched across the interior of a chamber to be scrubbed with high velocity jet streams or stretched along an array of objects to be cleaned as the swivel assembly traverses the cable from one end to the other. The cable passes through a coaxial bore in an elongated shaft carrying both a relatively stationary an input member for supply of high pressure liquid to the assembly and a rotatable output nozzle-carrying spray head member. The shaft is monolithic with multiple angularly spaced bores around the central bore and parallel thereto and sealed from the central bore carry high pressure liquid from the input member to the output spray head member with very low drag bearings and liquid seals being provided between relatively rotating liquid carrying components. The assembly includes multi-directioned nozzle elements on a rotatable spray head. Positive drive to rotate the spray head is achieved with a rotational speed controlling motor.Type: GrantFiled: August 20, 1999Date of Patent: July 11, 2000Assignee: Stoneage, Inc.Inventor: Gerald P.

Patent number: 6039056Abstract: The invention relates to machines for cleaning the inner surfaces of all kinds of tanks. The cleaning is processed by means of a nozzle (14) spraying a jet of cleaning fluid against the surface to be cleaned. Each nozzle (14) is rotatable around two axes, that enclose an angle. In order to be able to customize the working procedures of the machine to the geometry and size of the tank and to the kind of pollution, the machine comprises an electronic control and two independently operating drives (4) by means of which the rotational movement of the nozzle (14) around the two axes can be controlled.Type: GrantFiled: October 2, 1998Date of Patent: March 21, 2000Inventor: Diederik Geert Verbeek
