Ice cream cone

In 1924, the first U.S. patent for an ice cream cone rolling machine was issued to its inventor, Carl R. Taylor of Cleveland, Ohio, in which it was described as a “machine for forming thin, freshly baked wafers while still hot into cone shaped containers” for ice-cream. Multiple dies were designed on a turntable, such that when formed, the cone had time to cool and harden before rotating into position for release. The whole machine was to be set up beside a batter baking machine which provides the supply of the hot, flat wafers (No. 1,481,813).Image: detail of one die from the series set around the machines's turntable.
