IMPACT DRIVE SPRINKLER ABSTRACT OF THE DISCLOSURE An impact drive sprinkler is provided for projecting a water stream in a generally upward and outward direction from a water supply riser. The sprinkler includes a sprinkler body formed from a length of tubing (12) mounted for rotation on the riser (16) wherein the tubing is bent at a selected angle to define a smooth, substantially uninterrupted flow path (14) from the riser (16) to a discharge nozzle (18). An impact drive assembly (20) is mounted on the tubing (12) and includes a spring-biased drive arm (22) formed preferably from inexpensive stamped metal parts for interrupting the projected water stream at regular intervals and for impacting the tubing (12) to rotate the tubing in increments about the riser (16). The drive assembly is mounted on the tubing (12) at a position downstream from the tubing bend (28) such that the construction and operation of the drive assembly (20) is unaffected by the magnitude of the angular bend in the tubing.
