Abstract
A sprinkler discharges a column of water downwardly onto a deflector that has a plurality of peripheral tines with a respective non-radial tapered notch separating each adjacent pair of tines. Opposed cutouts with tabs in the central portion of the deflector combine with the notches and with depressed peripheral tabs to produce a predetermined spray pattern.
