Abstract: An animal-patterned sprinkling device includes a left and right animal-shaped housing halves, a water tube, several fitting washers, a fixing washer, upper and lower semispheric water discharging members and several sprinkling heads. At a top end and a bottom end of each of the animal-shaped housing halves are respectively formed two semicircular holes. Several posts and hollow cylindric columns are formed on inner faces of the left and right housing halves. The fitting washer and fixing washer are formed with rectangular teeth peripheries. The upper semispheric water discharging member has a central engaging tube which downwardly extends from a top end thereof. A lower end of the water discharging member is formed with four downward extending insertion plates. Four communicating tubes are disposed on a middle section of the engaging tube. Two eccentric stepped water discharging openings are formed at an upper end of the engaging tube.

Abstract: A novel speed adjustment device for control of the operation frequency of the splatter arm in a sprinkler adapted for watering a garden or a lawn. The speed adjustment device is provided with an adjustment knob which is disposed on top of a bias spring in connection to the splatter arm at one end and to the underside of the adjustment knob at the other end, and an urging spring is disposed on top of the adjustment knob so as to always urge the same downward. The underside of the adjustment knob is provided with a plurality of spaced stop protrusions which are in selective engagement with a pair of stop members disposed on the rotatable main body of the sprinkler so that the turning of the adjustment knob can vary the tension of the bias spring in connection to the splatter arm thereby the operation frequency thereof can be changed accordingly.
