Underground water discharging and sprinkling device

Claim 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.
