  • Patent number: 6433312
    Abstract: An electric roaster has a base housing which includes a first roaster tray mounted thereon, and a first heating element attached to a bottom side of the first roaster tray. The first roaster tray includes a surface slanting downward in a first direction from one side to the other side of the first roaster tray, and an oil collecting hole formed in the first roaster tray adjacent the other side of the first roaster tray. A collecting receptacle is disposed in the base housing below the oil collecting hole. A cover housing includes a second roaster tray mounted therein. One of the cover housing and the second roaster tray is connected pivotally to one of the base housing and the first roaster tray so that the first roaster tray is covered by the second roaster tray when the cover housing is turned to cover the base housing.

  • Patent number: 6429407
    Abstract: A toaster having an electronic circuit including a chip-on-board ASIC that controls the operation of toaster heating elements and an electromagnet to which relatively high voltage is applied to hold an armature carried by a bread carriage and toaster-operating assembly. The armature is freely suspended from a bread carriage and toaster-operating assembly and accurately guided onto the electromagnet when the bread carriage is lowered. The toaster has a one-piece main frame that includes both a base frame plate and a rear frame plate. Several economies are obtained by virtue the construction of the toaster. A one-piece control support member is mounted on the base frame plate that supports both mechanical and electronic assemblies for controlling the operation of the toaster in predetermined relative positions.

  • Patent number: 6364277
    Abstract: An armature assembly support pallet has armature assembly support surfaces which exhibit a magnetic field that magnetizes the portions of the armature shaft adjacent the support surfaces so that armature assembly is magnetically attracted to the support surfaces and thereby maintained in a precise axial position on the pallet as the pallet is conveyed between work stations. The magnetic field is preferably created by thin layers of magnetic material secured to upwardly-facing surfaces of V-shaped portions of support members or blocks affixed to the body of the pallet. The pallets may be used without changes or adjustments for supporting armature assemblies having a substantial range of various different configurations. Pallets of known construction, including those with adjustable support members, may be modified or retrofitted by providing them with magnetic support surfaces.

  • Patent number: 6364651
    Abstract: A substantial barrier to flow of liquid in a circumferentially-extending liquid conduit groove of a mold insert is provided by forming recesses or undercuts by undercutting the sidewalls of the liquid conduit groove, inserting a plate-like liquid dam within the liquid conduit groove, and clamping the dam in the liquid conduit groove by the use of a pair of locking screws or pins that extend through bores in the dam into engagement with inwardly-facing surfaces of the undercuts. The relationship between the inwardly-facing undercut surfaces and the locking members is preferably such that there is a progressively increasing interfering engagement of the locking members with the undercut surfaces resulting in increasing clamping pressures applied to the dam assemblies.

  • Patent number: 6351602
    Abstract: An upright radiant electrical heater has a reflector assembly supporting a vertically-extending heating element assembly that radiates energy through substantially 360 degree. The reflector assembly includes heat reflective panels that disperse heat horizontally over substantially 90 degrees through an open grill at the front of the heater and vertically in a substantially uniform manner so that hot spots are avoided. A fan forces room air into the heater from below the reflector assembly, upwardly through an air passage behind the assembly into an open control chamber at the top of the heater, and outwardly into the room through ducts along the top front edge of the assembly. A thermostatic control for the heating element assembly and the fan motor is located in the air passage at the top of the heater. The flowing air maintains the exterior of the heater relatively cool to the touch, allowing parts of the housing to be molded from a thermoplastic material into aesthetically-pleasing shapes.

  • Patent number: 6343543
    Abstract: A low cost toaster having a metal body and plastic end panels. The end panels have cooling inlet vents near their lower ends and the top wall of the metal body has air outlet vents. Ambient air admitted through the inlet vents flows upwardly through the toaster and outwardly through the outlet vents to provide a cooling effect sufficient to allow the use of inexpensive plastic material for molding the end panels. The toaster has a bread lifter made entirely from a wire rod, a bread lifter extension made entirely from a wire rod, and a toast color cam made entirely from a single piece of sheet metal.

  • Patent number: 6298770
    Abstract: A coffee maker has a housing having an upstanding tower, a carafe support platform extending horizontally forward from the lower end of the tower, and a fixed, tubular filter basket support extending horizontally forward from the upper end of the housing above the platform. A horizontal filter basket cover, including a water spreader, is disposed above the filter basket support and carried by the housing for pivotal movement about a vertical axis. A cover pivotal about a horizontal axis is provided over a water reservoir defined by the housing. A valve mechanism is provided that operates upon pivoting of the filter basket cover to selectively permit heated water to be supplied to the water spreader, thereby preventing burns or the like from heated water when the water spreader is not located above the filter basket support. The coffee maker also includes an electronic controller having a control pad on the front surface of the housing platform.

  • Patent number: 6283013
    Abstract: This invention relates to a tea steeper that enables an automatic drip coffeemaker to brew tea as well as coffee. The tea steeper comprises a cylindrical body having perforated side walls, a perforated bottom wall, and an open top surrounded by a support rim. A pair of upwardly extending finger grips are provided to enable one to easily grasp the tea steeper. In use, the support rim rests atop the spout of a carafe for suspending the tea steeper within the carafe. The carafe may also contain a pivotal lid which closes over the spout but does not engage the support rim or finger grip portions of the tea steeper resting atop the spout.
