    Abstract: An appliance for holding food items, such as marshmallows and hot dogs, for roasting against the face of an open fire includes food carrying skewers that are rotatably mounted on an axis generally perpendicular to the elongated frame of the device. A drive linkage, manually operated from the opposite end of the frame, rotates the skewers such that the food products are uniformly exposed to the same heating, resulting in uniformly cooked food items without burning.

  • Patent number: 6913433
    Abstract: A denesting apparatus for a stack of cup-shaped articles having peripheral outwardly extending rims includes a pair of uniquely machined rotary shafts which operate together to support the stack of nested articles and to denest and separate one article at a time as the stack passes vertically downwardly between the shafts. Each of the shafts includes at least one profiled surface portion which makes line contact with the lowermost cup rim and supports the stack, followed rotationally by a groove that engages the rim of the lowermost cup to denest and separate it from the stack.
