Zenith egg scale
the Zenith egg grader
 

This egg grader originates from the U.S.A.. The brand name is Zenith. Orlando W. Bedell from Earlville, New York is the maker of the first models. A lot of information about the Zenith egg graders is given in North American Egg Scales - from ABC to Zenith by Charley Amsbaugh. There are different versions and models. This typical American egg scale has a scale on which the weight per dozen eggs is given. This scale ranges from 18 to 30 ounces per dozen. The scale has a set screw and two adjustable screws with a black rubber cap. These can function as a stop to do a division into three weight classes. Lighter than = counterweight against the lower stop, heavier than = lower lever against the other stop. Moving in between = the intermediate weight class. According to an original leaflet, the Zenith would normally be supplied with a test weight to check the value of 22 ounces per dozen (22/12 oz = 52grams). The molded parts have a number. The name is cast in the base of the egg grader. The colors red and blue are characteristic of the Zenith egg scale.
