Abstract
A fire-protection sprinkler head having a base from which fire-retardant fluid emerges in a stream, a deflector plate spaced from the base for deflecting the stream into a spray pattern, and a throat in the base with a noncircular cross section selected to vary the shape of the stream and thereby vary the spray pattern.
