Meal calls at West Point in the 19th century were not what you might expect. In 1853, USMA regulations specified the following times and signals for meals:
7 A.M.: “Peas-upon-a-trencher, the signal for breakfast”
1 P.M.: “Roast-beef, the signal for dinner.” This was used on the Titanic and other ships into the 20th century for meal calls.
