Out of all our picks, the Krups is the only one that can feed a large group efficiently, producing four 1-inch-thick, 4½-inch square waffles at a time. But its shape also works for feeding just one or two people. As Will It Waffle? author Daniel Shumski pointed out, “You can always make four at a time if you want, or you could make fewer, or you could make four, freeze two.” Neither our runner-up nor our budget picks offer that option, since they make waffles that are big enough to serve only one or two people at a time.
The thermostat allows the automatic control of the temperature in the waffle iron. However, the "Twin-O-Matic" also has a thermometer -- a device that indicates the actual temperature of the iron. The principle behing the thermomenter is basically the same - a bimetallic strip is made with the property that its warping is a linear function of temperature. This strip is connected to a lever mechanism that causes the small needle to rotate. Hence, the position of the needle is a direct function of the temperature. The dial is calibrated to reflect this.
This illustration anthropomorphizes the Twin-O-Matic and notes that post-war demand for small appliances will be a "half billion dollars" (about $100 billion in 2005 dollars), and encourages dealers to sign up to sell Manning-Bowman appliances. This is actually a very sad artifact, because the Manning-Bowman company was in deep financial distress because they could not get materials -- particularly chrome -- during World War II. This was an attempt to sign up dealers so that credit and financing could be obtained to last out the materiel shortages imposed by the War. It did not work, and soon thereafter, Manning-Bowman sank into a sea of red ink. The company's assets, including its spectacular Art Deco designs, were sold to the Bersted Corporation of Fostoria, Ohio. Berstead watered down the designs and made low-priced "drug store" versions of many Manning-Bowman appliances. (The Sandwich Grill on our Kitchen Aplliances page is a good example of this "cheapening" process.) Alas, Manning-Bowman met an inglorious end, but it was merely a foretaste of the vast wave of shoddy appliances made in faraway dictatorships that suffocate the American marketplace today.
