Oscillating sprinkler

A sprinkler comprising:

• a support base member;
• an upper housing rotationally mounted to a top surface of the base member rotating about a vertical axis of rotation in a first direction;
• a liquid chamber in the upper housing for containing liquid;
• the upper housing comprising at least one outlet orifice extending through an outer wall and communicating with a liquid passageway and expelling liquid therefrom through the orifice;
• and
• a cap member rotationally mounted to the upper housing and rotating in a second direction relative thereto contrary to the first direction about a cap member axis of rotation, the cap member further having an internal liquid reservoir communicating with the upper housing liquid chamber and at least one outlet port for discharging liquid from the reservoir and the cap member rotates unitarily with the upper housing about the vertical axis of rotation and rotates simultaneously thereto about the cap member axis of rotation.

A sprinkler comprising:

• a support base member;
• an upper housing rotationally mounted to a top surface of the base member and tilting into varying angular attitudes relative to an axis of rotation extending through the base member as the upper housing rotates;
• a liquid chamber in the upper housing;
• the upper housing comprising at least one outlet orifice extending through an outer wall and communicating with the liquid chamber and discharging liquid therefrom at an expulsion angle of trajectory which varies as the angular attitude of the upper housing varies;
• and
• an arm member rigidly connected at one end to the upper housing and projecting therefrom, and the arm member tilting with the upper housing into the varying angular attitudes;
• and
• tilt actuation means contacting an arm member portion at a location remote from the upper housing and acting through the arm member to tilt the upper housing into the varying angular attitudes.
