Rocking-Stool Churn: Rock the Churn, the Dashers Ride With It

A churn worked by a dasher or crank needs a strong arm for half an hour. Enoch Thomas of Harrisonburg, Virginia, received US 753, dated 30 May 1838, for a rocking churn: a rectangular or curved churn of tin or wood fastened on a stool with four legs resting on rockers, two dashers "perforated with holes, or ... made in the form of a balustrade" set in grooves so they move with it, and a vent or wire gauze over the opening. "A small child or adult may then rock the churn as an amusement, and the butter will be quickly produced." This rung works out the rocking pace, then prints the perforated dashers and gauze vent, builds the churn on a rocking stool, and makes butter.

The churning it does

The embedded blueprint makes butter by agitating cream. Thomas lets rocking do the agitating.

Read US 753

"Among the many advantages which my churn possesses over others is, that it gathers the butter sooner and more easily than any other churn. This cannot be done, however, so well with dashers immovable. They must be taken out in order to collect the butter and one inserted in the middle."

Make the churn

Take a food-safe storage box about 180 × 90 × 110 mm. Glue pairs of plywood strips inside both sides at one and two thirds of its length as grooves for the dashers. Cut a 26 mm hole in the lid and press the vent into it.

Rock and gather

Let 500 ml of heavy cream stand until it reaches about 15 °C, checked with the thermometer. Pour it in, fit the lid and rock steadily; time until the butter comes. Then take both dashers out, set one in the middle, and rock slowly to gather it, as he did. Pour off the buttermilk, add cold water, churn a few turns and pour off again until it runs clear; work in a pinch of salt and weigh the butter.

History and honest limits

**Enoch Thomas** of Harrisonburg, Rockingham County, Virginia, received US 753, dated 30 May 1838. If the churn is small, one dasher may suffice; the lid may be left off for air, or the top made flat and covered with wire gauze to keep out flies; the churn is easily cleaned by pouring off the buttermilk, throwing in water and rinsing. He claimed the gauze covering. **Honest limits.** A storage box and printed dashers stand in for his tin or wooden churn. FDM prints hold food in their layer lines, so wash well and replace when worn. Your times and weights are the result.
