Patent number: 5607224Abstract: A housing for an underwater lighting fixture includes a wet niche formed from plastic and provided with three alternative grounding pathways. A conductor strap is attached to the niche by a threaded lug which extends through the strap and an adjacent wall of the niche to permit an internal ground wire and an external ground wire to be connected to the strap. As a further grounding assurance, the lighting fixture is grounded through a bracket which attaches to the conductor strap. The bracket also serves as a current collector to receive electrical charge from the surrounding water.Type: GrantFiled: March 31, 1995Date of Patent: March 4, 1997Assignee: H-Tech, Inc.Inventors: Samuel Tobias, Donald R. Davidson, Robert H. Hanes

Patent number: 5493811Abstract: An apparatus and method are disclosed which operate to automatically deliver liquid to a plant growing medium in a pot from a receptacle positioned above the plant growing medium. The liquid flows from the receptacle under the influence of gravity and is supplied to the plant growing medium at predetermined drip rate, which may be manually adjusted.Type: GrantFiled: February 22, 1994Date of Patent: February 27, 1996Inventors: Michael E. Tobias, Samuel Tobias

Patent number: 5432688Abstract: A housing for an underwater lighting fixture includes a wet niche formed from plastic and provided with a grounding strap. The grounding strap is attached to the niche by a threaded lug which extends through the strap and an adjacent wall of the niche to permit an internal ground wire and an external ground wire to be connected to the strap. As a further grounding assurance, the lighting fixture may be grounded through the grounding strap, which mechanically and electrically attaches the lighting fixture to the niche.Type: GrantFiled: March 12, 1993Date of Patent: July 11, 1995Assignee: H-Tech, Inc.Inventors: Samuel Tobias, Donald R. Davidson, Robert H. Hanes

Patent number: 5271561Abstract: An outlet assembly for a water receptacle, such as a swimming pool, spa or the like, includes a pair of interchangeable discharge nozzles, one being a rotary discharge nozzle and the other being a linear discharge nozzle. A user may selectively interchange the rotary discharge nozzle and the linear discharge nozzle by withdrawing and inserting them through an outlet port sized and shaped so as to permit the user's hand to fit therein.Type: GrantFiled: July 2, 1992Date of Patent: December 21, 1993Assignee: Hayward Industries, Inc.Inventors: Samuel Tobias, Robert M. Messinger, Donald R. Davidson

Patent number: 5115974Abstract: A device for creating a waterfall effect and a fountain effect in an adjacent swimming pool spa or the like, has a tubular manifold with spray orifices which produce streams of water. The manifold is positionable so that the streams of water can be aimed away from the housing at an inclined angle, thereby producing a fountain effect, or so that the streams of water can be directed to fill a reservoir located within the housing and adapted to discharge water in the form of a waterfall.Type: GrantFiled: August 21, 1991Date of Patent: May 26, 1992Assignee: Hayward Industries, Inc.Inventors: Samuel Tobias, Fred Hollinger

Patent number: 5068033Abstract: An underdrain assembly contained within a swimming pool filter has a plurality of laterals, each of which is pivotable between a non-operating position and an operating position. Each of the laterals is threadedly attached to the underdrain assembly so that they can be replaced individually by unscrewing them from the underdrain assembly without removing the underdrain assembly from the filter. The laterals can be locked in their operating positions by either a reversible locking mechanism or an irreversible locking mechanism. With the laterals in their non-operating positions, the underdrain assembly and the laterals can be inserted into the filter as a unit.Type: GrantFiled: May 10, 1990Date of Patent: November 26, 1991Assignee: Hayward Industries, Inc.Inventors: Samuel Tobias, Fred T. Hazlehurst

Patent number: 4985943Abstract: A hydrotherapeutic jet for a hydrotherapeutic receptacle employs three nozzels and two separate mixing chambers. A primary stream of water flows through the first nozzel to create a low pressure condition which sucks air into the first mixing chamber, causing the primary stream to be mixed with the air. The primary stream is discharged through the second nozzle into the second mixing chamber, thereby creating another low pressure condition which sucks a secondary stream of water from the hydrotherapeutic receptacle into the second mixing chamber and hence causes the aerated primary stream to be entrained with the secondary stream. The air/water mixture is then discharged from the second mixing chamber into the hydrotherapeutic receptacle by te third nozzle.Type: GrantFiled: September 8, 1989Date of Patent: January 22, 1991Assignee: Hayward Industries, Inc.Inventors: Samuel Tobias, Robert M. Messinger

Patent number: 4982460Abstract: A jet fitting for a hydrotherapeutic receptacle includes an internal chamber which functions as a mixing chamber as well as a suction chamber. A primary stream of water is supplied to the mixing chamber in such a manner that a low pressure condition is created within the mixing chamber for entraining a secondary stream of water which flows from the hydrotherapeutic receptacle to the mixing chamber and for entraining air from an outside source.Type: GrantFiled: March 28, 1989Date of Patent: January 8, 1991Assignee: Hayward Industries, Inc.Inventors: Samuel Tobias, William E. Treene, George E. Williams

Patent number: 4967696Abstract: A dog collar has a receiver unit which is selectively and remotely actuated by a conventional transmitter. When actuated, the receiver unit emits a sound audible to the dog, thereby allowing an individual to communicate with his dot. The emitted sound can be either a simple tone or a human voice.Type: GrantFiled: January 25, 1989Date of Patent: November 6, 1990Inventor: Samuel Tobias

Patent number: 4941217Abstract: A jet fitting for a hydrotherapeutic receptacle includes an internal chamber which functions as a mixing chamber as well as a suction chamber. More particularly, a primary stream of water is supplied to the mixing chamber in such a manner that a low pressure condition is created within the mixing chamber for the purpose of entraining a secondary stream of water which flows from the hydrotherapeutic receptacle to the mixing chamber. The combined streams exit the fitting together so as to increase its discharge flow rate.Type: GrantFiled: March 13, 1989Date of Patent: July 17, 1990Assignee: Hayward Industries, Inc.Inventors: Samuel Tobias, William E. Treene, George E. Williams

Patent number: 4818389Abstract: A skimmer for skimming water from a swimming pool or spa is provided with entraining means for entraining additional water from the pool or spa to thereby increase the flow of water into and out of the skimmer. The entraining means includes two nozzle members which cooperate with each other to jet an entraining stream of water through the skimmer. The skimmer is also provided with isolating means for isolating the entraining stream of water from the rest of the water flowing through the skimmer. The isolating means includes actuating means for selectively actuating and deactuating the isolating means such that the skimmer can be operated at a normal flow rate when the isolating means is actuated and at an increased flow rate when the isolating means is deactuated.Type: GrantFiled: December 31, 1987Date of Patent: April 4, 1989Assignee: Hayward Industries, Inc.Inventors: Samuel Tobias, Thomas Pinelli, Robert M. Messinger, Fred T. Hazlehurst

Patent number: 4629557Abstract: A test ring for a pump strainer is threadedly attached to both a housing and a cover of the strainer in such a manner that the cover can withstand relatively high internal pressure. When the test ring is detached from the cover, the cover is adapted for quick and easy removal from the strainer housing.Type: GrantFiled: July 16, 1985Date of Patent: December 16, 1986Assignee: Hayward Industries, Inc.Inventor: Samuel Tobias

Patent number: 4593420Abstract: A hydromassage fitting employs a directional nozzle to inject an aerated jet of water into the interior of a water receptacle, such as a bathtub, spa, therapy tank or swimming pool. The directional nozzle is mounted in the fitting so as permit water to drain around the nozzle and into the water receptacle when the fitting is not in use, thereby inhibiting the collection of water in the fitting. Pockets and voids within the fitting are eliminated or sealed in order to further inhibit the collection of water in the fitting.Type: GrantFiled: October 11, 1985Date of Patent: June 10, 1986Assignee: Hayward Industries, Inc.Inventors: Samuel Tobias, Robert M. Messinger
