Patent number: 4660766Abstract: A rotary sprinkler head comprising a sprinkler body devoid of any operative dynamic seals for communicating a source of water under pressure with an outlet for directing water under pressure communicated therewith into an atmospheric condition in a primary stream having a generally vertically extending axis. A rotary distributor is provided which has surfaces for engaging the primary stream (1) to establish a reactionary force component acting on the distributor in a direction tangential to the rotational axis thereof so as to effect rotational movement thereof about its axis of rotation and (2) to direct the primary stream engaged thereby in the form of a pattern forming stream or streams including at least one stream moving away from the distributor in a direction having a substantial component extending outwardly from the generally vertical axis of the primary stream so as to define the radius of the circular spray pattern.Type: GrantFiled: September 18, 1985Date of Patent: April 28, 1987Assignee: Nelson Irrigation CorporationInventors: Barton R. Nelson, Larry P. Meyer, George L. Sesser

Patent number: 4659018Abstract: An orbiting nozzle dispersion apparatus is adapted for use in combination with a robot to form a dispensing system. The orbiting nozzle dispersion apparatus has a dispensing tube with a first end for receiving the materials to be dispersed and a second or nozzle end from which the material is finally dispersed onto the workpiece. The dispensing tube is compliantly supported at one end and supported at the nozzle end for orbital but not rotational motion about an axis.Type: GrantFiled: May 31, 1985Date of Patent: April 21, 1987Assignee: Westinghouse Electric Corp.Inventor: Burt H. Shulman

Patent number: 4651925Abstract: A spray device having a plurality of rotating nozzles directing sprays of a high pressure fluid in a circular pattern against an object being cleaned. The nozzles are mounted on the ends of supply pipes extending radially outwardly from a hub connected to a hollow crankshaft. The crankshaft is connected to a source of high pressure fluid through a supply conduit which is connected to the crankshaft by a rotary union. The rod of a double action piston is connected to the crankshaft and rotates the crankshaft and nozzles upon linear reciprocating movement of the piston rod. The piston cylinder is pivotally mounted on a valve block which has a pair of ball check valves which are actuated by a rocker bar mounted on the cylinder. A small quantity of the high pressure fluid is directed into the valve block from a manifold and is injected alternatively into the ports of the cylinder upon pivotal movement of the cylinder to reciprocate the rod and rotate the crankshaft and connected spray nozzles.Type: GrantFiled: June 13, 1985Date of Patent: March 24, 1987Assignee: Washtronics, Inc.Inventor: Larry W. Harris

Patent number: 4632312Abstract: An impact drive sprinkler is provided from a relatively small number of easily assembled components which can be formed predominantly from lightweight molded plastic or the like. The sprinkler includes a unitary sprinkler body having a lower riser tube rotatably supported within a one-piece bearing sleeve adapted for connection to a water supply riser or the like, wherein the lower riser tube is joined to an upper range tube through which an irrigation water stream is projected. An oscillatory impact drive arm and a spring are snap-fit mounted with a controlled spring preload onto the sprinkler body for spring-loaded rotation of the drive arm toward a position with a deflector spoon unit thereon interrupting the projected water stream.Type: GrantFiled: December 14, 1984Date of Patent: December 30, 1986Assignee: Rain Bird Consumer Products Mfg. Corp.Inventors: Kenneth W. Premo, Billy J. Hobbs, Jr.
