Abstract: A linear water feed apparatus for use in agricultural irrigation includes a linear-move machine with a mobile truss assembly supporting a plurality of individual sprinklers and adapted for movement in a specified direction across a field to be irrigated. The truss assembly is oriented transverse to the specified direction, and a supply pipe is arranged in the specified direction along or within the field to be irrigated. The supply pipe mounts a plurality of water supply hydrants at spaced locations along the pipe, each of the hydrants enclosing a water supply valve. A docking station is supported at one end of the truss assembly closest to the supply pipe, and is adapted to engage and open successive ones of the water supply valves in the plurality of hydrants. The docking station assembly includes a docking station that is suspended from a frame for floating movement about at least three mutually perpendicular axes.

Abstract: A pop-up sprinkler assembly includes a cylindrical housing having a cap on an upper end thereof, the cap having an opening, a lower end of the cylindrical housing having an internal thread for attachment to a source of pressurized water. A stem is mounted in the cylindrical housing with a spring radially between the stem and the cylindrical housing for normally biasing the stem to a retracted position within the cylindrical housing. The stem is extendable through the opening in the first cap to an extended position when water under pressure is supplied to the cylindrical housing. The stem has a threaded upper end to which an alternative sprinkler head is attached. An adapter housing is received over the cap and secured to the cylindrical housing, the sprinkler housing having an open upper end, the adapter housing having a diameter sufficient to receive the alternative sprinkler head when the stem is in the retracted position.
