Two-Compartment Gate Churn: Paddles Drive the Cream Through a Slotted Gate Into an Open Side and Round Again

Silas F. Lefler of Racine, Wisconsin, received US 19,034, dated 5 January 1858, for a churn divided into a closed compartment, where spiral paddles turn under a housing, and an open one, joined by gateways at the partition's foot. A slotted gate in one gateway breaks the current, and the cream, driven into the open side, "is exposed to the action of the fresh air" before it returns. This rung prints the partition, gate and paddle hubs, builds the churn and makes and gathers butter.
