Patents by Inventor William Wade Marder

William Wade Marder has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5819405
    Abstract: Plug-in connectors primarily intended for connecting lighting fixtures into system circuitry, the connectors include selector mechanisms which allow selection of a hot conductor or conductors necessary for energization of the fixtures. The connectors of the invention allow selection of a specific circuit at the job site rather than pre-wiring of a fixture to a specific circuit during factory assembly, a given fixture then being rapidly installed by plugging of the connector into a tapping port in electrical cable extending between fixtures in an installation. The selection mechanism of the invention acts primarily to change the wiring configuration of the associated fixture with the hot leg or legs of the fixture being movable to adapt to a desired specific circuit. The invention further encompasses use of the apparatus of the invention in a method for rapidly wiring fixtures into system circuitry, thereby resulting in labor and job cost savings.
    Type: Grant

  • Patent number: 5679023
    Abstract: A dual-port electrical cable female connector head primarily useful for branch circuit extension of and for fixture tapping into a relocatable wiring system, the female connector head of the invention is located at one end of a length of electrical cable which carries one or more circuits and into which lighting fixtures or other electrical loads are to be tapped at predetermined locations of the wiring system by connection to tapping ports formed in respective female connector heads. A male connector head joined to the length of cable at the other end thereof connects to a branch circuit port formed in a female connector head of an adjacent length of cable in the wiring system.
