Abstract
The horizontal sidewall sprinkler has a sprinkler body with a passage having an outlet and a deflector with a vertical portion supported forwardly of the outlet by a diverging boss at the culmination of frame arms extending from the sprinkler body and a generally horizontal portion with a planar lower surface supported above the vertical portion by integral strips having a reverse curvature. The generally horizontal deflector portion is inclined upwardly from the sprinkler axis at an angle between 0.5.degree. and 5.degree. and the vertical deflector portion has an opening extending across the width of that portion beneath the planar surface of the horizontal portion. The vertical portion also has a central opening beneath the sprinkler axis with a forwardly directed upwardly inclined tab and two further openings on opposite sides with rearwardly directed tabs to distribute liquid in the region beneath the sprinkler.
