Spiral-Vane Spring-Agitator Churn: Vanes That Snap Springs on the Bottom
Watson wanted "the lower stratum of the cream" kept "in brisk motion" while a dasher lifted the rest.
Peter H. Watson of Rockford, Illinois, assignor to Nathaniel S. Wheeler of Painesville, Ohio, received US 5,573, dated 16 May 1848, for a churn with a rotary spiral dasher — flat vanes fixed between arms ninety degrees apart, so they twist into spirals — over "elastic vibrating agitators": a removable cross on the bottom carrying curved springs that the vanes press down and release. A tube in the lid lets air in and a tube in the side lets it out, kept circulating by the dasher. He set the churn obliquely on a frame to turn the winch.
This rung counts the springs' snaps, then prints the vane spiders and the spring cross, twists flat vanes between them, and makes butter.

A spiral that lifts the cream before it
The embedded blueprint lifts cream with an Archimedean screw in a tube. Watson's twisted vanes lift it in the open churn and let it fall through the air.

"On the upper side of these arms a series of curved elastic pieces of wood or metal are secured by one end, the end projecting from the arm at right angles or nearly so and inclining upward; as the vanes of the dasher revolve in the direction indicated by the arrows Figs. 2 and 3 they depress the springs f f f in its passing over them, but the moment the vane has turned far enough to release the spring the latter flies up again to its former position."

Print two vane spiders (/uploads/blueprints/spiral-vane-spring-agitator-churn-spider.stl), the agitator cross with its twelve tongues (/uploads/blueprints/spiral-vane-spring-agitator-churn-agitator.stl) and the crank arm (/uploads/blueprints/spiral-vane-spring-agitator-churn-crank-arm.stl). Print the cross in PETG if you have it: its thin tongues must flex and spring back. Print in PETG at 0.2 mm layers, 30 % infill, 4 walls; wash before first use.

Glue the spiders on a 10 mm square hardwood shaft 110 mm apart, the upper turned 90° to the lower. Cut four strips of thin stainless sheet about 60 × 130 mm, deburr them, and seat each in a lower spider's slot and the next upper slot round, so it twists a quarter turn into a spiral, as his did. Glue them in.

Set the agitator cross on the floor of a food-grade bucket, the shaft's foot through its centre hole into a drilled seat. Drill the lid at the centre for the shaft, and fit a short tube in the lid and another near the top of the side for the air. Glue the crank arm and a dowel handle on the shaft. Prop the bucket at an angle on a pine frame for cranking.

Crank and make butter
Let the heavy cream stand until it reaches about 15 °C, checked with the thermometer. Pour in 1.5 litres. Crank the way the springs incline, so the vanes press them down and let them fly up; time until the butter comes. Lift out the cross to gather the butter with the dasher alone, as he allowed. Pour off the buttermilk, add cold water, churn a little and pour off again until it runs clear; work in a pinch of salt and weigh the butter.

History and honest limits
History and honest limits
**Peter H. Watson** of Rockford, Winnebago County, Illinois, received US 5,573, dated 16 May 1848, assigned to Nathaniel S. Wheeler of Painesville, Ohio. The dasher had eight horizontal arms; each vane could be "one broad piece or of several narrow pieces"; the agitators could be removed once the butter was separated. He claimed "the combination of the elastic vibrating agitator with the rotary spiral dasher."
**Honest limits.** A bucket, printed spiders and a printed spring cross stand in for his tub and wooden or metal springs; our dasher has four vanes on two spiders. FDM prints hold food in their layer lines, so wash well and replace when worn. Your times and weights are the result.
