Abstract
Abstract In order to accommodate odd shaped areas to be sprinkled, an impulse sprinkler is supported by apparatus which permits tilting the impulse sprinkler from the vertical in any radial direction. As a result, the sprinkler pattern is altered from a circle (or portion of a circle) to an ellipse-like (or portion thereof) shape.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
132 words
In a sprinkler system including a sprinkler head for automatically distributing a discontinuous stream of water through a predetermined arc in response to the flow of water, the sprinkler head being provided with means for adjusting the angular distribution of water issuing therefrom, said sprinkler head further including support means for the sprinkler head, the improvement comprising in combination: swivel coupling means disposed between the support means and the sprinkler head for altering the axis of the sprinkler head, said coupling means being the sole element necessary to support and to maintain the sprinkler head in alignment with a predetermined axis; whereby, an odd shaped distribution pattern may be achieved by tilting said swivel coupling, and hence the sprinkler head, from the vertical and adjusting the angular distribution of the sprinkler head.
Claim 2
Dependent Claim
