Abstract: An impact drive sprinkler for connection to a water supply riser, comprising: a sprinkler body formed from a length of tubing having a bend generally intermediate its length separating first and second tubing portions disposed angularly with respect to each other, said tubing defining an open flow path for passage of water therethrough; a journal bearing assembly carried about said first tubing portion for connecting said first tubing portion to the riser with said flow path disposed for flow thereinto of water from the riser, whereby the water flows through said tubing for discharge as a projected water stream from said second tubing portion, said journal bearing assembly including means for permitting rotation of said tubing generally about the axis of the riser, said first tubing portion extending through said journal bearing assembly and terminating with a radially outwardly flared flange, said flange defining a relatively smooth contoured water inlet for guiding water flow from the flow from the riser into said flow path with minimum flow turbulence; and an impact drive assembly mounted on said second tubing portion for impacting one side - of said second tubing portion at a regular frequency to cause rotation of said tubing in a succession of angular increrents generally about the axis of the riser; said flow path extending through said first tubing portion, said bend and said second tubing portion without substantial surface interruption.
