Ice cream cups

In 1903, a U.S. patent was issued for an ice cream cup mold to Italo Marchiony (No. 746,971). He came from Italy in 1895. From a pushcart on New York's Wall Street, he sold ice cream and lemon ice served in his baked waffles which he had folded by hand into the shape of a cup while still warm. Shortly, he had a chain of 45 carts operated by men he hired. Marchiony met the need for mass production with his invention of a multiple recess mold based on a waffle-iron. The bottom half of the mold was divided, to make it easy to separate it from the delicate baked cups. With two rows of five in each mold, it produced 10 cups at a time. In 1904, Marchiony took his confection to the Louisiana Exposition in St. Louis where he had the idea for the cone shape.
