ABSTRACT:
An oscillating sprayer for spraying water on surrounding areas including a cylindrical main body and a support for rotatably supporting a lower part of the main body. An inclined nozzle extends radially outwardly and upwardly from the main body and an adjustable water stream deflector is disposed on the main body for adjusting the height of a water stream ejected from the nozzle by intercepting the water stream at a plurality of points spaced from the main body. An oscillating arm is rotatably supported on an upper part of the main body, the oscillating arm including water impact deflectors at one end thereof for causing rotation of the oscillating arm in a first direction away from the water stream by intercepting the water stream, the oscillating arm being engageable with the water stream deflector when the oscillating arm is rotated in a second direction towards the water stream to thereby cause step-by-step rotation of the main body in the second direction due to impact of the oscillating arm with the water stream deflector. A removable pivot is disposed on an upper end of the main body for pivoting the oscillating arm about a vertical axis and a spring is disposed between the pivot and the oscillating arm for biasing the oscillating arm in the second direction towards the water stream. A reversing mechanism is provided for reversing the step-by-step rotation of the main body from the first direction to the second direction.
