Patent 7578453 was granted and assigned to Kohler Co. on August, 2009 by the United States Patent and Trademark Office.
A handshower is disclosed providing two different radial spray patterns that can be selectively operated. There is a handle adapted for connection to a water supply, a nozzle head having an outer sleeve and an inner chamber connected to the handle, and an axially extending waterway positioned in an inner chamber of the nozzle head. On the sleeve there is an array of outlets running from the inner chamber to an outer radial face. The waterway has an axially extending channel and multiple sets of radially extending orifices. The sleeve is rotatable relative to the waterway from a first position where the channel is in communication with a first group of outlets to a second position where the channel is in communication with at least some of the outlets that are not in the first group.
