  • Patent number: 5277105
    Abstract: A conveyor oven module has a very low profile so that more oven modules may be stacked to give a greater baking capacity in the same "foot print" without the top conveyor being higher than the five and a half feet from the floor, which is the generally accepted maximum height for people to reach. Almost all serviceable parts are in the front of the oven. The oven modules are self-contained so that an oven module may be serviced while the remainder of the oven modules in the stack continue to operate.

  • Patent number: 4964392
    Abstract: An oven for baking objects, especially pizzas, has an indirect drive for enabling it to accommodate differences in commercial power on a worldwide basis, by simply changing the ratio of gears, sprockets or pulleys. Various access panels and doors on the oven may be opened to facilitate installation, removal, and maintenance of the oven without requiring a significant partial disassembly thereof. An access window is held under gravity in either an open or a closed position in order to eliminate clips, springs, and the like, which may tend to become fatigued and break as a result of the repeated heating and cooling.
