This design "consists in a perforated open-ended flangeless shell, adapted for application to the common vertical dash-churn, and having at its sides vertical tubes or pipes extending through the cover or lid for the reception of hot or cold water, which thus modifies the temperature of the cream as required without mixing therewith" (lines 8-15).
