ABSTRACT:
Applicant's sprinkler head is molded with a large number (such as twelve or sixteen) of potential orifices and directing channels with the orifices all plugged or occluded with comparatively light barriers or plugs of the molded plastic material which are readily punctured and removed by the user. In this way the user may select among many possible watering patterns including not only the above described full, one-half, and one-fourth circles, but may also choose to punch one orifice, giving a thirty or twenty-two and one-half degree arc, then skip one or two plugs, then punch another plug or two. In this manner one or a number of orifices may remain blocked making it possible to, for example, water a thirty degree arc, skip sixty degrees, water another thirty of sixty degree arc, etc. Many such patterns become possible. In one of the embodiments disclosed, the design allows access to the puncturable barriers or plugs from the bottom which means that the user must puncture the desired pattern or orifices before installing the head on the riser pipe. A second embodiment allows access to the puncturable barriers from the head as installed.
