Appl. No.:

09/876241

Assignee:

L. R. Nelson - Peoria IL

International Classification:

B05B 306

US Classification:

239251, 2392251, 239261, 239263, 239264, 239279, 239280

Abstract:

A rotating bearing assembly for a sprinkler coupled to a pipe segment is disclosed. The bearing assembly has a stem which permits fluid flow. The stem has a bottom open end with a collar and a top open end which is connected to a cap. The cap allows connection to a sprinkler head which rotates from water pressure through the pipe segment. The stem conduit rotates in relation to a sleeve which is frictionally fitted within the pipe segment. A plurality of washers is located between the collar and the bottom of the sleeve to provide a water seal under high pressure conditions. Another group of washers is located between the top of the sleeve and the cap to provide additional sealing under low pressure conditions.

Abstract:

A self propelled sprinkler is disclosed. The sprinkler has a support body with a drive unit which drives two rear wheels. The drive unit is powered by water pressure supplied through a hose which is coupled to the drive unit via a hose coupler. The drive unit has a cylindrical drive chamber with circular impeller in fluid communication with the hose coupler. The impeller is rotated by the water pressure and is mechanically connected to a lateral shaft. The shaft is connected to the rear wheels. Reduction gearing from the impeller to the shaft governs the speed of the sprinkler. The reduction gearing is achieved through a series of sun gears, carrier disks and planet gears. The drive unit also has an outlet which has a socket which allows the exit of the pressurized water. The socket allows the insertion of any variety of sprinkler heads. Thus, the sprinkler allows a variety of water distribution patterns.

International Classification:

F16K 504

US Classification:

251209, 251309

Abstract:

A pistol grip hose nozzle is disclosed which allows proportional water control in accordance with the position of a rotatable valve. The hose nozzle has a handgrip section with an inlet water passage and an outlet section with an outlet water passage. One end of the handgrip section is connectable with a hose. The other end of the inlet water passage ends in a valve seat with an aperture. The valve seat contains a valve having a flow control cylinder. The flow control cylinder has a non-circular opening which when aligned with the aperture allows water to flow to the outlet water passage. The flow control cylinder is attached to a control knob which allows a user to grip the hand grip portion and rotate the control knob and the flow control cylinder to vary the water flow. The non-circular opening allows the amount of water flow to the outlet water passage to be linearly proportional to the rotational position of the control knob.

US Classification:

239570, 239526, 239391, 251 45

Abstract:

A one touch valve for activating fluid flow between an inlet conduit and an outlet conduit is disclosed. The valve has a flow cylinder defining an inflow chamber in fluid communication with the inlet conduit and an outflow chamber in fluid communication with the outlet conduit. The flow cylinder includes an end plate and an intermediate plate having a center collar with an aperture. A flexible diaphragm is provided with a sealing surface in contact with the collar to create a seal. The diaphragm has an edge coupled to the intermediate plate and a small diameter hole providing fluid contact between the inflow chamber and an intermediate chamber which is defined by the intermediate plate of the flow cylinder. A plunger is placed on the diaphragm to create a seal with the opposite surface of the diaphragm from the sealing surface. A shaft has one end connected to the plunger and extends through the aperture of the diaphragm.
