  • Patent number: 5168798
    Abstract: A portable rotisserie is disclosed which can be readily assembled and disassembled. The rotisserie includes front and back walls and two side walls each of which includes at its extremities complementary connecting means so that the walls can be assembled in the form of a rectangular frame. The front wall includes two plates between which are mounted a plurality of engaging idler gears and a drive gear for rotating the idler gears. Notches are provided in the upper surface of the plates of the front wall for receiving a sprocket gear attached to a skewer, the other end of which is supported in the back wall. A drive gear engages the idler gear so that when it is rotated, either manually or by motor, rotation of the idler gears causes the skewers mounted in the notches to rotate.
