Abstract
Abstract A toaster having a vertically orientated toasting compartment with a hinged cover a hinged bottom which during a toasting operation is held in a horizontal position by means of a pawl. The pawl is withdrawn to discharge the toasted bread by means of a tripping device controlled by an adjustable timing device which thus determines the toasting period. Means are provided for operatively connecting the bottom, the cover and the timer so that lifting of the cover causes the bottom to be lifted to horizontal position and locked by the pawl and the timing device to start when the cover is subsequently closed. After the period of the timing device has run out, it actuates the tripping device to release the compartment bottom.
