  • Patent number: 7143957
    Abstract: A sprinkler device includes a sprinkler body having a longitudinal center axis, an inlet at one end and an outlet at an opposite end. A rotatable nozzle is supported within the body and defines a first flow path lying on the longitudinal center axis and a second flow path terminating at a discharge orifice offset from the longitudinal center axis. A rotor plate is supported on the nozzle for orbital motion about the longitudinal center axis and for rotation about a second axis offset from the longitudinal center axis. The rotor plate has a plurality of grooves formed therein, and arranged to cause the rotor plate to rotate about the second axis when a stream emitted from the nozzle impinges on the plate, such that the nozzle assembly is caused to rotate about the first axis.

  • Patent number: 6372311
    Abstract: A multiple piece bodyside molding includes a cover piece connected to a base piece. The cover is formed in a manner and shape so that it may be chrome-plated while reducing the likelihood of bath/tank contamination during the chrome-plating process. Subsequent to being chrome-plated, the cover is connected to the base so as to form the resulting bodyside molding. The cover may be attached to the base via ultrasonic welding, vibration welding, snap-on connectors, or via heat-deforming or extension tabs in different embodiments of the invention.
