Abstract

An underground water discharging and irrigation sprinkler including an elongated housing having a riser tube slidably mounted therein, a water motor being mounted adjacent the lowermost end of the riser tube and a discharge nozzle being provided adjacent the other end thereof, and water inlet means connected with the housing for selectively raising the riser tube within the housing to elevate the nozzle thereof above the ground and lowering the riser tube within the housing to retract the nozzle belowground.

Claims

1. In a water discharging and irrigation sprinkler the combination of a chamber providing housing adapted to be fixed underground far beneath the ground surface, a long riser tube slidably and rotatably carried by the upper part of the housing of a length sufficient to be raised a plurality of feet above a ground surface at its upper end, a water motor fixedly secured to the lower end of the riser tube for travel therewith in slidable upward and downward movement acting as a piston on the walls of the housing chamber, means in the water motor for passage of pressurized water from the housing chamber into the riser tube said water motor having means to rotate the riser tube by water passing therethrough, water inlet means connected with the housing chamber below the water motor to move the water motor bodily upwardly through the chamber of the housing under impetus of the pressurized flow of water upwardly within the housing chamber, nozzle means slidably and rotatably carried by the riser tube at the upper portion thereof located in the top of the riser tube and extensible above the riser tube by upward force of water on the riser tube for jet discharging water from the riser tube, and water inlet means at the upper end of the housing for pressurized flow of water into the housing chamber above the water motor to lower the water motor within the housing chamber upon stoppage of water pressure by the first mentioned water inlet means below the water motor.

2. In a water discharging irrigation sprinkler, the combination of a housing adopted to be fixed underground below the ground surface having a chamber therein, a riser tube slidably and rotatably mounted in the housing of a length adapted to be placed underground and raised far above the housing and above the ground surface at its upper end, a water motor secured to the lower end of the riser tube located within the housing for slidable upward and downward movement in the chamber acting as a piston in the chamber, means in the water motor for passage of water from the housing chamber and the motor into the riser tube, said water motor having means to rotate the riser tube as water passes through the motor, water inlet means connected with the housing chamber below the water motor to move the water motor bodily upwardly through the housing chamber, means in the water motor to move water into and through the riser tube, nozzle means carried by the upper portion of the riser tube for extension and retraction at its upper portion for discharging water from the riser tube at a location above the riser tube far above the ground surface, and a water inlet at the upper end of the housing chamber for passage of water into the chamber above the water motor to retract the water motor and riser tube within the housing chamber upon stoppage of water pressure flow by the first mentioned water inlet means.

3. The device of claim 2 in which the nozzle means consists of a casing having a slidable piston for movement along and within the riser tube under pressure of water moving upwardly in the riser tube to a point where the nozzles will laterally discharge water above the ground at a location far above the riser tube, and means to retract the nozzle means and its casing into the riser tube upon stoppage of water flow upwardly through the riser tube.

4. The device of claim 2 in which the means to retract the nozzle tube consists of spring means which is biased to retract the nozzle means in the riser tube upon stoppage of upward water flow through the riser tube.

5. The device described in claim 2 in which the means to rotate the riser tube of the water motor includes a rotary member having a fixed non-slidable connection with the lower end of the riser tube.

6. In a water discharging and irrigation sprinkler the combination of a chamber providing housing adapted to be fixed underground far beneath the ground surface, a long riser tube slidably and rotatably carried by the upper part of the housing of a length sufficient to be raised a plurality of feet above a ground surface at its upper end, a water motor fixedly secured to the lower end of the riser tube for travel therewith in slidable upward and downward movement acting as a piston on the walls of the housing chamber, means in the water motor for passage of pressurized water from the housing chamber into the riser tube said water motor having means to rotate the riser tube by water passing therethrough, water inlet means connected with the housing chamber below the water motor to move the water motor bodily upwardly through the chamber of the housing under impetus of the pressurized flow of water upwardly within the housing chamber, nozzle means carried by the riser tube at the upper portion thereof for discharging water from the riser tube, and water inlet means at the upper end of the housing for pressurized flow of water into the housing chamber above the water motor to lower the water motor within the housing chamber upon stoppage of water pressure by the first mentioned inlet means below the water motor.
