Abstract
A temperature sensitive timing assembly for a toaster appliance includes a single bimetallic element having a first portion connected to a support bracket, which in turn is mounted on a mounting bracket for pivotal movement relative to the mounting bracket. A spring is positioned between the mounting bracket and the support bracket to bias the support bracket toward the mounting bracket. A stop is mounted to the mounting bracket which locks the support bracket in a fixed position when actuated by the toaster carriage assembly at the beginning of a toasting cycle. The bimetallic element has a second portion which operatively activates the toaster lock release assembly at the end of a toasting cycle. The bimetallic element also has a third portion which operatively allows the support bracket to reposition at the end of a toasting cycle so as to provide virtually immediate initiation of the next toasting cycle providing substantially the same toast color as the previous toasting cycle.
