Abstract
Abstract An economical energy saving toasting apparatus includes a housing with an interior baffle defining a toasting chamber therein and an inlet for the introduction of the product to be toasted into the chamber. The housing also includes an outlet through which the toasted product is dispensed. A conveying assembly for conveying the product from the inlet through the toasting chamber to the outlet is also included within the housing. Mounted within the toasting chamber is a first set of resistive heating elements that are electrically connected in a circuit and continuously energized during the operation of the heating apparatus. A second set of heating elements is also included in the heating chamber and connected to a timer in order to be energized for only selected periods of time. A micro-switch is also included in the apparatus to actuate the timer and a micro-switch actuator is positioned in the inlet and adjacent to the conveying device so as to be engaged by the product prior to entry into the toasting chamber. The engagement of the product actuates the micro-switch to energize the timer and the second set of heating coils for a predetermined period of time.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
103 words
A toasting apparatus comprising a housing defining a toasting chamber, a first opening defined in said housing for the introduction of a product into said toasting chamber, a second opening defined in said housing for the removal of said product after toasting, means for conveying said product from said first opening to said second opening, first heating means in said chamber, said first heating means being continuously energized, second heating means in said chamber, and first switch means mounted adjacent said conveying means so as to be engaged by said product to energize said second heating means for a predetermined period of time.
Claim 2
Dependent Claim
103 words
A toasting apparatus comprising a housing defining a toasting chamber, a first opening defined in said housing for the introduction of a product into said toasting chamber, a second opening defined in said housing for the removal of said product after toasting, means for conveying said product from said first opening to said second opening, first heating means in said chamber, said first heating means being continuously energized, second heating means in said chamber, and first switch means mounted adjacent said conveying means so as to be engaged by said product to energize said second heating means for a predetermined period of time.
Claim 3
Dependent Claim
26 words
The toasting apparatus set forth in claim 1 wherein said first switch means includes a timer for controlling the time said second heating means is energized.
Claim 4
Dependent Claim
