Valve-and-Cap Churn Dasher: Cream Driven Through Hinged Valves and Out of a Perforated Top Against a Sliding Cap
Parker Wineman of Loydsville, Ohio, received US 24,898, dated 26 July 1859, for a churn dasher that is itself a closed vessel. Pushed down, it takes cream in under hinged valves on its sides; the cream mingles with the air inside and is driven out through the holes of its perforated top against a cap that slides on the shaft up to a stop. The butter falls to the bottom of the dasher, and a segment of it is taken out to remove the butter.
This rung prints the dasher for a 20-litre bucket.

"As the dasher is forced downward, the cream is forced under the valves (d) into the dasher, where it instantly mingles with the contained air, and is forced through the perforations (i) of the top of the dasher (c) against the cap with such violence as to burst the particles of cream or milk in which the butter is contained."

Slide the body onto the shaft and pin its hub. Hang a flap over each port on a 3 mm pin through the lugs, and check it swings out freely and falls back shut. Press the top c into the body and pin its hub. Slide the cap f on above it and push the stop pin g through, so the cap can lift 20 mm. Set the side panel's foot on its lip and slide the 3 mm locking pin over its top. Put the handle on, and pass the shaft through a 28 mm hole in the bucket's lid.

FreeCAD model of this build, half the bucket and lid cut away: the octagonal dasher with its flaps swung open, the perforated top, the cap lifted to its stop, the shaft and handle. It was checked at three heights of the stroke with the flaps shut and open and the cap down and up.

Pour about 8 litres of heavy cream at about 15 °C into the bucket, checked with the thermometer, and put the lid on. Work the handle up and down about 100 mm, keeping the dasher's floor off the bucket's floor, and time it. When the butter has come, lift the dasher out, pull the panel's pin, take out the panel and scoop out the butter. Pour off the buttermilk, wash the butter in cold water until it runs clear, work in a pinch of salt and weigh it.

**Parker Wineman** of Loydsville, Belmont County, Ohio, US 24,898, 26 July 1859, "Churn-Dasher". He claimed the dasher with its perforated top, movable cap and hinged valves. He gives no sizes and says the valves may be arranged in various ways. Fig. 1 draws the dasher with flat sides, which we copy; our flaps hang over ports near the top as in Fig. 2. Every size is ours, and our printed build has not been churned with.
