Abstract

An oscillating lawn sprinkler which gives more uniform distribution of water and includes a base, a water driven motor mounted in the base, a crown gear attached to the base, a pinion on the gear meshing therewith, a link having one end connected to the center of the pinion and the other to the drive shaft of the motor concentric with the gear and a connecting rod pivoted to the perimeter of the pinion gear and to one end of rocking arm of the sprinkler outlet.

Claims

1. An oscillating lawn sprinkler comprising a base, a motor mounted on the base and having a rotor actuated thereby, a crown gear fixed to said base concentrically about said rotor;

a pinion gear engaged by said crown gear;

a link fixed to the rotor and to an end of which the pinion gear is rotatably mounted;

a sprinkling outlet on said base including a rocker arm pivoted on said base and having a lever end integral therewith at a lower end thereof, said arm and said lever end forming an obtuse angle therebetween and a connecting rod pivoted to the lower end of said lever arm and to the perimeter of said pinion gear whereby said rod continually travels in both an axial direction and in an orbital direction as said pinion gear rotates.

2. The invention as recited in claim 1, wherein said angle is between one-hundred and one-hundred-ten-degrees.

3. The invention as recited in claim 2, wherein said angle is about one-hundred-six degrees.
