HOW THE TOASTER OPERATES
Put two slices of bread in the Toaster. The slice in the slot marked "One Slice" will
depress the Trip Lever, causing the Trigger Lever Assembly to close the contact points.
The elements will then heat up, and the expansion of the Center Element wire will allow
the Bread Lifter Assembly to go down slowly under its own weight.
When the bread is
toasted,
the heat radiated from the outer surface of the bread, in the
slot marked "One Slice", will cause the Thermostatic Blade to snap to "off" position,
causing the contact points
open. Then,
to
the elements cool, the wire in the Center

rising sufficiently in bread slot when bread is removed. This in turn would keep
the other end (E) (Diagram I) from moving out far enough to allow Trigger (C) to
drop into position shown. The friction might be due to Trip Lever (E) rubbing
guide wires, as there is not sufficient end play at the bearing points for free
action; or the ends of the Trip Lever entering the bearings might not be
straight, thus causing binding. If Trip Lever appears to be free of excessive
friction, then it is likely that clearance indicated by dimension (D) (Diagram
I) is insufficient. To check this clearance it will be necessary to remove End

5 . Bread Rises Too Slowly
(a) This complaint may be due to the impatience of the user. Actually the toasting
cycle from a cold start takes less time than any toaster previously
manufactured. The toasting cycle will vary with voltage changes, dryness of
bread, or if toaster is cold or warm. Under normal conditions (Which means
testing with moderately fresh bread on 115 Volts A.C. with Toaster set at
Medium) the total toasting cycle will vary from
