  • Toaster and overhead support
    Patent number: 4645909
    Abstract: A toaster is mountable on a heat reflective overhead support which is adapted to be secured to a supporting surface such as the underside of a cabinet. The support is recessed from the front of the toaster so as to accomodate the lip of the cabinet. The toaster is provided with a shelf or grill which is movable between a first, heating position and a second, delivery position below and forward of the heating position. The grill is lockable in the heating position by a locking mechanism which comprises a releasable latch bar. An infrared (IR) sensor senses IR radiation produced by a food article supported on the grill. The IR sensor is part of an electrical circuit which controls the heater elements as well as an electromechanical element which releases the latch bar. When the latch bar is released, a spring assisted parallelogram linkage transfers the grill by gravity from the heating position to the delivery position.

  • Method of making cookware
    Patent number: 4613070
    Abstract: The outer surface of a stainless steel utensil and one surface of an aluminum disk are cleaned and then separately heated at different temperatures. Thereafter, the disk is superimposed over the utensil and metallurgically bonded directly thereto by the application of pressure. Accumulated stress is relieved by cooling the bonded metal members to a temperature below 250.degree. F., followed by reheating to 700.degree.-950.degree. F.
