Patent number: 8985483Abstract: Disclosed is a method and device to control a spray pattern produced from a spraying device consisting of a plurality of individual jets that form the resulting spray pattern. The trajectory of each individual jet is controlled by orienting the nozzle-like feature that produces each individual jet, thereby producing a variety of spray patterns. This is accomplished utilizing the flexible properties of elastomeric or rubber-like materials. In addition to allowing for deformation or movement to remove possible obstructions to the fluid flow, this flexibility property also permits for specific, controlled movements, whereby it is possible to control the trajectory of the fluid issuing from the device. These rubber-like materials can include specific features that allow the material to be deformed in a controlled fashion so as to predictably control the trajectory of the streams issuing from the individual nozzles.Type: GrantFiled: July 3, 2012Date of Patent: March 24, 2015Inventor: John E. Petrovic

Patent number: 8479772Abstract: A diverter valve receives fluid from an inlet port. A camshaft is rotated within a housing to slide a cam follower along an axis to regulate fluid flow to an outlet port when the camshaft is rotated. The housing provides an inlet port and first and second outlet ports. The camshaft includes a cam lobe that is offset relative to a rotational axis of the camshaft. The cam follower is supported on the cam lobe and is movable along a longitudinal axis to selectively block at least one of the first and second ports. In one embodiment, first and second cam followers are used to selectively block outlet ports that are arranged approximately 90 degrees from one another. The first and second cam followers move in first and second directions transverse to one another. In another embodiment, a single cam follower is used to regulate flow through two outlet ports that are arranged approximately 180 degrees from one another.Type: GrantFiled: December 19, 2005Date of Patent: July 9, 2013Assignee: Masco Corporation of IndianaInventors: John E.

Patent number: 6311734Abstract: The showerhead security cover prevents unauthorized access to a connector of a shower assembly. The connector secures the showerhead to the shower arm, the connector, showerhead, and shower arm being standard without any modification required. The showerhead security cover comprises a housing and a lock. The lock is integral with the housing. Once the lock is engaged, the housing encases the connector and prevents access to the connector. Once the lock is engaged, there is no substantial rotational movement of the connector relative to the shower arm. One end wall of the housing seats against an end of the connector during engagement preventing any substantial axial movement of the connector relative to the connector. The housing is strong enough to prevent engagement with the connector even when the housing is grasped with pliers. Disengagement is enabled by the use of a special tool to allow authorized access to the connector.Type: GrantFiled: November 12, 1999Date of Patent: November 6, 2001Assignee: Alsons CorporationInventor: John E.

Patent number: 5114570Abstract: A water filter cartridge has a cylindrical shell. A conduit runs between closing end walls and is disposed within a filtration material. There are additional openings in the respective end walls for communicating the flow of water through the material. A water filtration element of a porous medium is shaped to nest within a portion of the shell encircling a corresponding portion of the filtration material and defining space between the medium and the inner side wall of the shell with that space being in the water flow path from one of the end walls and the material through the medium. A reference color is exhibited over a portion of the exterior side wall of the shell adjacent to the location of the medium inside the shell, and the medium exhibits a given color upon beginning of usage but changes color with continued usage in response to its entrapment of matter in the water. The shell is transparent over the medium to enable the user to compare the medium color to the reference color.Type: GrantFiled: August 14, 1989Date of Patent: May 19, 1992Assignee: Teledyne Industries Inc.Inventors: Sharon L.

Patent number: 4958629Abstract: The housing of an oral hygiene device is attachable to a water faucet. A regulator within the housing responds to the water which is subject to pressure variation. The regulator accommodates that variation in developing automatically a stream of water at a constant pressure. A turbine within the housing is caused to rotate in response to energy in the stream. A piston pump draws water deflected by impellers on the turbine and forms that water into a series of pulses. A flexible hose coupled to the housing includes a handle for directing the pulses against the teeth and gums of a user at a desired pressure.Type: GrantFiled: June 21, 1988Date of Patent: September 25, 1990Assignee: Teledyne Industries, Inc.Inventors: Steven L.
