Dynamic viscous damping of the turbine output power train is used to control the rotational speed of the turbine. This prevents overspeeding when the turbine is air driven, and also when the turbine is water driven, under abnormal conditions such as blockage of a bypass area designed to control the turbine speed by limiting flow to the turbine. The same mechanism can be used to impose a lower rotational speed in the turbine during normal operation in conjunction with a turbine optimized for lower speed operation to reduce the required gear reduction in the power train.Type: GrantFiled: February 6, 2004Date of Patent: June 19, 2007Inventor: Carl L Kah, Jr.

Patent number: 7226000Abstract: A sprinkler includes a housing disposed on a base, and a sprinkler tube coupled to a oscillating mechanism, for allowing the sprinkler tube to be rotated relative to the housing and the base by the oscillating mechanism, the oscillating mechanism includes a receptacle disposed within the housing, and a casing rotatably attached to the receptacle, and coupled to the sprinkler tube, for allowing the casing and the sprinkler tube to be rotated relative to the receptacle. A device may be used for swinging the casing and the sprinkler tube relative to the receptacle in reciprocating action, to allow the water to smoothly or swiftly flow out of the sprinkler tube in various kinds of water spraying patterns.Type: GrantFiled: August 30, 2005Date of Patent: June 5, 2007Assignee: Yuan Pin Industrial Co., Ltd.Inventor: Chen-Tung Huang

Patent number: 7086609Abstract: A swinging lawn sprinkler including a sprinkling control unit with a gear-operated transmission mechanism attached to one side of a sprinkler mount. A limiting connector having a water outlet connector engaged at one side is correspondingly matched to the gear-operated transmission mechanism and a spraying member. A main driving wheel, an adjusting seat, and a water inlet connector are sequentially coupled at the other end of the gear-operated transmission mechanism. The adjusting seat is equipped with a limiting cavity for a power switching device made up of a plurality of power units in linkage with a pivoting shaft and a pair of limiting zones with elastic pieces and pressure guide members adapted to be pivotally mounted to activate the shift of angles of a flow switch plate.Type: GrantFiled: May 24, 2004Date of Patent: August 8, 2006Assignee: Aquastar Industries Inc.Inventor: Gary Wang

Patent number: 7040553Abstract: A Pelton type turbine is mounted in a riser of a pop-up sprinkler for rotation about a horizontal axis and drives a central bevel pinion gear through a gear train reduction. Upper and lower bevel gears supported on a vertical drive shaft are simultaneously driven in opposite directions by the central bevel pinion gear. A clutch slides up and down along the drive shaft to engage radially extending teeth formed on its upper and lower sides with complementary teeth formed on the upper and lower bevel gears. One end of a yoke is coupled to the clutch and the other end is moved vertically by an over-center mechanism to shift the direction of rotation of a nozzle turret connected to the upper end of the drive shaft. The over-center mechanism is tripped back and forth by a shift disc engaged by a pair of tabs of a turret coupling assembly.Type: GrantFiled: July 3, 2001Date of Patent: May 9, 2006Assignee: Hunter Industries, Inc.Inventor: Michael L. Clark

Patent number: 6840460Abstract: A sprinkler includes an outer housing having a lower end connectable to a source of pressurized water and a riser that is vertically reciprocable within the outer housing between extended and retracted positions when the source of pressurized water is turned ON and OFF. A nozzle is mounted at an upper end of the riser for rotation about a vertical axis. A Pelton turbine is mounted inside the riser for rotation about a horizontal axis, as distinguished from a vertical axis. A drive mechanism connects the turbine to the nozzle so that when the source of pressurized water is turned ON the resulting rotation of the turbine by the pressurized water will rotate the nozzle. The turbine as well as a gear train reduction and a bevel gear reversing mechanism are assembled inside a self-contained clam-shell drive subassembly before being inserted into the riser.Type: GrantFiled: June 1, 2001Date of Patent: January 11, 2005Assignee: Hunter Industries, Inc.Inventor: Michael L. Clark

Patent number: 6772775Abstract: A drive assembly for a sootblower which provides a non-constant rate of rotational motors of the lance tube through the use of non-circular gears in the drive assembly. The drive assembly is used to provide a uniform or near uniform rate of progression of a jet of cleaning medium ejected from the lance tube along a surface to be cleaned.Type: GrantFiled: December 20, 2001Date of Patent: August 10, 2004Assignee: Diamond Power International, Inc.Inventors: Dean C. Ackerman, Clinton A. Brown, James H. Hipple, Kamal E. Kassouf, Don W. Smith
