Ventilating Paddle Rocking Churn: Hinged Paddles That Strike One Way and Slip the Other
Cook set out to let "a current of fresh air" into the churn "to hasten the production of the butter and to improve its quality."
George W. Cook of Schenectady, New York, received US 3,460, dated 28 February 1844, for "Cook's Ventilating Churn": a semi-cylinder balanced on pivots so it rocks easily, its top closed by thin boards except a narrow opening in the middle. Inside, two frames at about 45° from the vertical, inclined opposite ways, carry perforated paddles hung on gudgeons. As the vessel is canted, one set swings square to its frame and strikes the cream while the other turns flat against its stops.
This rung works out how the paddles hang, then prints the ends, frames and paddles, bends a stainless semi-cylinder, and makes butter.

"When the vessel is canted, as represented in Fig. 2 the paddles N drop down or turn on their gudgeons assuming a position nearly at right angles to the sides of the frame of the paddles. At the same time the paddles N2 of the other frame turn until they are in a line parallel with the sides of the frame when they strike against pins or stops O2 inserted into the sides of the frame on the inside thereof."

Cut a 0.5 mm stainless sheet 160 mm wide and about 252 mm long, deburr it, and bend it round a 160 mm form into a half circle. Seat it in both ends' grooves in silicone. Cut two thin plywood boards to close the top, sloping 10–15° down toward the middle and leaving a narrow opening there, as his.

Hang the paddles and the vessel
Hang the paddles and the vessel
Hang four paddles in each frame on M3 screws through the frame's sides, so they swing freely and lie against the stops one way. Set the two frames on the ledges inside the vessel, inclined opposite ways. Build a pine stand with two posts and hang the vessel on an M8 bolt through each end's boss, so it is nicely balanced.

Rock and make butter
Rock and make butter
Let the heavy cream stand until it reaches about 15 °C, checked with the thermometer. Pour 500 ml through the middle opening. Rock the vessel steadily from side to side; time until the butter comes. Lift out the frames, then 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
**George W. Cook** of Schenectady, New York, received US 3,460, dated 28 February 1844. Blocks on the vessel's convex side met a cross bar of the frame to stop it canting too far; handles in its side rocked it; iron straps strengthened it; a plugged aperture drew off the milk; a button held the two frames in place. He claimed combining with a rocking churn "floats or paddles arranged in and hinged to a frame."
**Honest limits.** Stainless sheet, plywood and printed parts stand in for his wooden vessel and frames. FDM prints hold food in their layer lines, so wash well and replace when worn. Your times and weights are the result.
