Patent number: 5276307Abstract: An outdoor grill of the type having a base, a cover, a food-supporting grill and a heating element includes an electrical housing having a support member removably disposed within the outdoor grill, and a housing member secured to the support member. The housing member is shaped to define a cavity wherein at least one electrical connection is located. The top and the sides of the housing member define a nonperforated surface which substantially prevents substances damaging to the at least one electrical connection from entering the cavity. In case damaging substances do enter the cavity, the bottom of the housing member defines a surface having at least one vent for venting the substances from the housing.Type: GrantFiled: June 11, 1992Date of Patent: January 4, 1994Assignee: Rival Manufacturing CompanyInventor: David T. Higgins

Patent number: 5255595Abstract: A cookie maker includes a housing having a lid and a base, a heat conducting element supported within the lid of the housing, a cookie pan disposed within the base of the housing, and a heating element supported within the housing and operative to heat the cookie pan. The cookie pan and the heat conducting element cooperate to define a baking cavity having a height in the range of 0.5 inches to 2 inches.Type: GrantFiled: March 18, 1992Date of Patent: October 26, 1993Assignee: The Rival CompanyInventor: David T. Higgins

Patent number: 5176067Abstract: An apparatus for grilling food includes a base, a reflector positioned within the base, a heating element mounted upon the base and spaced above the reflector, and a food-supporting grill. The reflector includes a downwardly sloped bottom surface having a central region shaped to define a flavor well and a plurality of perforations disposed outside of the flavor well to direct drippings away from the flavor well.Type: GrantFiled: March 18, 1992Date of Patent: January 5, 1993Assignee: Rival Manufacturing CompanyInventor: David T.

Patent number: 4622889Abstract: A percolator/dispenser is disclosed which includes an insulated container having a hinged lid. A percolator heater tube and basket are mounted inside the container, and a manually operated pressure pump is included in the lid of the container. This pressure pump operates to pump air from outside the container to the inside of the container when operated. A discharge spout is movable between a vented position, a pump position, and a sealed position. A pressure lock system prevents the spout from being moved from the sealed position to the pump position when excessive pressure is present within the container. A lid stop system prevents the lid from being closed when the spout is in the pump position. A lid lock system prevents the lid from being opened when the container is pressurized.Type: GrantFiled: December 10, 1985Date of Patent: November 18, 1986Assignee: Rival Manufacturing CompanyInventors: William A. Chappell, David T. Higgins, Michael D. Reynolds, William J. Tweed

Patent number: 4512246Abstract: A percolator/dispenser is disclosed which includes an insulated container having a hinged lid. A percolator heater, tube, and basket are mounted inside the container, and a manually operated pressure pump is included in the lid of the container. This pressure pump operates to pump air from the outside of the container to the inside of the container when operated. A discharge spout is movable between (1) a vented position, in which a vent path is provided between the spout and an upper portion of the interior of the container, (2) a dispensing position, in which the spout is connected to a tube which extends down to a lower portion of the interior of the container, and (3) a sealed position, in which the spout is sealed. An interlock is provided which insures that the percolator can not be activated unless the spout is in the vented position, thereby automatically preventing overpressurization of the insulated container due to inadequate venting during operation of the percolator.Type: GrantFiled: July 10, 1984Date of Patent: April 23, 1985Assignee: Rival Manufacturing CompanyInventors: William A. Chappell, William J. Tweed, David T. Higgins

Patent number: 4464983Abstract: A percolator/dispenser is disclosed which includes an insulated container having a hinged lid. A percolator heater, tube, and basket are mounted inside the container, and a manually operated pressure pump is included in the lid of the container. This pressure pump operates to pump air from the outside of the container to the inside of the container when operated. A normally open vent path is provided between a spout of the container and the upper portion of the interior of the container. When the manually operated pump is operated, a vent valve is controlled to close this vent path in order to seal the container such that air introduced into the container by means of the pump operates to force liquid out of the spout of the container.Type: GrantFiled: December 27, 1982Date of Patent: August 14, 1984Assignee: Rival Manufacturing CompanyInventors: William A. Chappell, William J. Tweed, David T. Higgins

Patent number: 3995103Abstract: An electrical bussing and jumper assembly for use with electrical switching devices such as circuit breakers in a three-phase distribution system. The bussing and jumper assembly comprises a plurality (three) of relatively thin, wide, bus plates stacked together in a compact sandwich-like array. Each of the plates has a plurality of jumper portions extending transversely through openings or cutouts provided in the bus plates superimposed thereover. The bus plates are insulated from each other by means of insulative coatings (e.g., of polyvinyl chloride) formed on the plates and also by means of sheets of insulative material (e.g., of polyethylene terephthalate) disposed between the coated bus plates and having openings therein aligned with the openings in the bus plates. Switching devices for use in a current distribution system are attached to the jumper portions of the bus plates, using threaded openings provided in the jumper portions.Type: GrantFiled: December 11, 1975Date of Patent: November 30, 1976Assignee: Zinsco Electrical ProductsInventors: Donald F. Gehrs, David T. Higgins

Patent number: 3961129Abstract: An electrical bussing and jumper assembly for use with electrical switching devices such as circuit breakers in a three-phase distribution system. The bussing and jumper assembly comprises three relatively-thin, wide bus plates stacked together in a compact sandwich-like array. Each of the plates has a plurality of openings therein defining a pair of parallel side portions and a plurality of jumper portions transverse to and bridging the side portions. The jumper portions of bus plates are variously concave (top bus plate), flat (center bus plate) and convex (bottom bus plate) and spaced from each other such that when the bus plates are stacked together, the jumper portions are arranged in a ladder-like array and central portions of the jumper portions are all in a common plane. The bus plates are insulated from each other by means of insulative coatings (e.g., of polyvinyl chloride) formed on the plates and also by means of sheets of insulative material (e.g.Type: GrantFiled: December 11, 1975Date of Patent: June 1, 1976Assignee: Zinsco Electrical ProductsInventors: Donald F.
