Abstract: An oil jet assembly includes a body, a tube, a cap insert, a ball, and a spring. The body includes a bore passing longitudinally through the body; a tube aperture passing through the body near a first end of the body; and an opening at a second and opposite end of the body. The tube is attached to the body and in fluid communication with the tube aperture. The cap insert is positioned within the bore of the body. The cap insert includes a bore that passes longitudinally through the cap insert to form a wall. The cap insert also includes an oil exit aperture passing though the wall and is in fluid communication with the bore of the body. The ball and spring are positioned within the bore of the insert cap. The spring is positioned between the ball and the first end of the body.

Abstract: A sprinkler head guard includes a body with a passage. The body has a depth permitting the guard to be removably embedded adjacent to a sprinkler head commonly used with an in-ground sprinkler irrigation system. The passage of the body is adapted to permit a sprinkler head commonly used with an in-ground sprinkler irrigation system to pass through the body skyward from the in-ground sprinkler irrigation hoses.
