Rubber-Pipe Pump Churn: A Pulley Rolls Milk Through a Tube in a Ring and Jets It Through Gauze

Loren J. Wicks of Racine, Wisconsin, received US 24,686, dated 5 July 1859, for a churn that is a rolling-tube pump. An india-rubber pipe runs from the bottom of the milk box once round the groove inside a ring and up into a smaller box on top. A pulley on a fast crank rolls round the ring on the pipe and drives the milk up in a stream against two gauze partitions hung under the top box's cap. The broken milk runs back through a screen of fine wooden strips into the box below, the butter staying behind; the stream keeps going until all the butter is out. This rung builds it with silicone tubing, a printed ring and pulley, and pine boxes.
