Horizontal sidewall sprinkler
First Claim
1. A horizontal sidewall sprinkler comprising a sprinkler body adapted to be connected to a source of fire extinguishing liquid and having a passage with an outlet of selected diameter to convey the liquid along a generally horizontal sprinkler axis, a pair of arms extending from the sprinkler body, and a deflector having a vertical portion extending substantially perpendicularly to the sprinkler axis and supported by the sprinkler arms in spaced relation to the sprinkler passage outlet and having a generally horizontal portion supported from the vertical portion at a location above the sprinkler axis, the generally horizontal portion of the deflector having a substantially planar lower surface facing the sprinkler axis and being inclined upwardly from the sprinkler axis at an angle of at least 0.5°
- , and the vertical deflector portion having a first opening above the sprinkler axis and beneath the horizontal deflector portion, a second opening below the sprinkler axis with a forwardly projecting tab projecting from a lower edge of the opening, and two further openings disposed below and on opposite sides of the sprinkler axis with rearwardly projecting tabs extending therefrom.

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° and 5° 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.
