Patent number: 6899285Abstract: A protruding nozzle assembly, mounted in a side wall of a swimming pool in communication with a source of water, will eject through a nozzle of a nozzle housing a stream of water at a predetermined angle relative to the adjacent side wall surface. During each erection and retraction of the nozzle housing precipitated by initiation and cessation of water flow to the nozzle assembly, the nozzle housing will rotate incrementally to provide a plurality of streams of water defining a fan-like area from each nozzle as such nozzle comes into fluid communication with an opening in a cover enclosing the nozzle housing. Each nozzle is canted to a different angle above the adjacent surface to assist in cleaning sloping parts of the side wall/bottom surface junction and to assist in cleaning any adjacent structures extending from the side wall.Type: GrantFiled: April 16, 2003Date of Patent: May 31, 2005Assignee: Paramount Leisure Industries, Inc.Inventors: John M.

Patent number: 6874696Abstract: The adjustable sprinkler riser includes an outer and an inner telescoping member that telescopically interface with each other. A protrusion is spaced from a proximal end of the outer telescoping member. A first joint member slidably interfaces with the outer telescoping member, and a second joint member slidably interfaces with the inner telescoping member. The second joint member may be selectively secured to the first joint member to restrict movement of the inner telescoping member relative to the outer telescoping member. In such a condition, areas of vulnerability to breakage in the joint members and inner telescoping member are offset from each other to provide greater strength to the adjustable sprinkler riser. In addition, manufacturing the adjustable sprinkler riser is simple because the first and second joint members may be conveniently placed on the telescoping members, and there is no need to form threads or other intricate structures on the telescoping members.Type: GrantFiled: June 23, 2003Date of Patent: April 5, 2005Assignee: Orbit Irrigation Products, Inc.Inventors: Kent C.

Patent number: 6863226Abstract: A rotary sprinkler comprises a body and a rotor. The body has an inlet bore, an outlet bore, and an internal cavity therebetween. The inlet bore has an upstream end connectable to a water supply pipe and a downstream end formed as a jet nozzle. The outlet bore has an upstream end with a rim. The rotor has an axially extending shaft with an axial shaft channel and at least one vane with a vane channel extending away from the shaft and having an outlet constituting an outlet of the sprinkler. The shaft channel and the vane channel define a smooth water flow passage having an open cross-section. The shaft is inserted in the outlet bore of the body to enable free rotation of the rotor. The sprinkler further comprises a retaining ring that is assembled to the upstream end of the shaft of the rotor, is disposed in the internal cavity of the sprinkler body, and is adapted to abut the rim of the outlet bore, thereby carrying axial forces applied to the rotor.Type: GrantFiled: April 22, 2003Date of Patent: March 8, 2005Assignee: Netafim (A.C.S.)

Publication number: 20040232257Abstract: A spray chamber has a spray system and a ventilation system. The spray system includes a compressor and spray jets that are positioned 360° about a user, from head to toe. A pump sends tanning lotion from a container, through a manifold, where it is distributed to the spray jets via conduits. The tanning lotion is dispensed in the form of a mist having particles sufficiently large in size that they rapidly descend to the floor where they are collected for disposal. The mist clears the booth in approximately 30-90 seconds, without the need for an evacuation system such as a fan or filter.Type: ApplicationFiled: February 24, 2004Publication date: November 25, 2004Inventor: Ralph Venuto

Publication number: 20040195362Abstract: An improved rotating stream sprinkler of the type having a rotatable spray head with an offset nozzle port through which a water stream is projected outwardly, resulting in a reaction force for rotatably driving the spray head to sweep the water stream over a surrounding terrain area. The spray head is rotatably mounted on a body adapted for connection to a pressurized water supply, with interengaging bearing components providing predetermined friction brake torque resisting spray head rotation. By appropriately designing the nozzle port area and offset geometry, drive torque and brake torque is maintained at a substantially constant ratio for relatively slow and substantially constant spray head rotational speed over a range of normal water supply operating pressures. A downthrust spring retains the bearing components in engagement when the water supply is turned off, but does not contribute to friction brake torque when the water supply is turned on.Type: ApplicationFiled: April 2, 2003Publication date: October 7, 2004Inventor: Samuel C.

Patent number: 6799732Abstract: A sprinkler head assembly comprised of a base located at the upper end of a riser tube and which base carries an insert with an opening allowing for distribution of water. In accordance with the present invention, a control valve is located directly at the sprinkler head assembly. The control valve may be located in a stationary or shrub head which would be connected to a base or otherwise to a riser tube. The control valve could be located in a pop-up shaft, pop-up sprinkler head, or in a retrofit coupling or adapter located between a riser tube and sprinkler head. The control valve would rely upon a screw capable of being threadedly moved into a duct generally perpendicular thereto and which would have a diametral size somewhat larger than the duct. Moreover, the screw would be provided with an opening having a diameter approximately equal to that of the duct. The opening would be alignable with the duct in one position and when rotated would completely block the flow in another position.Type: GrantFiled: December 19, 2001Date of Patent: October 5, 2004Inventor: Teodore Sirkin
