A wobbling sprinkler head apparatus is provided for use in irrigation systems such as self-propelled mechanically moving irrigation systems, in which the wobbling sprinkler head faces downward from the water supply conduit. The sprinkler head has a body having a water inlet and a connection to the water supply conduit and a nozzle for directing a stream of water from the sprinkler body. The sprinkler head has one or more arms extending from the body around a water deflecting head to support a support collar. The water deflecting head is movably attached to the sprinkler head body and has a water deflecting surface positioned to deflect water directed thereagainst from the nozzle and to rotate the water deflective head. A mass having a weight of greater than 0.5 pounds is removably attached to the support collar to dampen vibrations caused by the wobbling sprinkler head and may be interchanged between different masses to meet different operating conditions.

Wobbling sprinkler head

A wobbling sprinkler head is provided, especially for use in irrigation systems such as self-propelled mechanically moving irrigation systems, in which the wobbling sprinkler head faces downward from the water supply conduit. The sprinkler head has a body having a water inlet as well as an attachment for connection to the water supply and a nozzle for directing a stream of water from the sprinkler body. The sprinkler head has one or more arms extending from the body around a water deflecting head. The water deflecting head is movably attached to the sprinkler head body and has a water deflecting surface positioned to deflect water from the nozzle and move the water defecting head. The bottom of the water deflecting surface has a protruding member extending therefrom, for interacting with a second protruding member extending from the arms of the sprinkler head body. The protruding members can have magnets of opposing polarity mounted therein. Thus, the water deflecting head has a wobbling motion while distributing water from the rotating sprinkler head to thereby vary the sprinkling action.

An improved rotary head sprinkler having a self-contained tool attached thereto for facilitating the assembly or the disassembly of a similar rotary head sprinkler. In a first embodiment of the invention a wrench or tool is attached to a sprinkler for coupling with a portion of a spindle cavity for enabling a rotary force to be exerted on the spindle coaxial with the longitudinal axis thereof, whereby the first end of the spindle may be coupled or decoupled from the sprinkler body. The wrench may also be used for coupling with other removable portions of another rotary sprinkler head. The wrench is attached adjacent a distended end of an impulse arm of the sprinkler head for increasing the oscillating period thereof.
