Roller-and-Float Gathering Churn: Floats That Fold Onto Rollers to Press the Butter
Dutcher wanted the whole process — churning, gathering and working the butter — done "without removing it from the churn."
Davis Dutcher of Springfield, New York, received US 8,143, dated 10 June 1851 (antedated 15 February 1851), for a churn with a curved-bottom box and a dasher whose stationary arms carry eight-sided rollers, braced by angular strips, and whose swinging arms carry floats. Churning, the floats stand out against shoulders; reversed, "the floats will fall back, by the resistance of the cream, upon the rollers, presenting a curved surface for directing the particles of butter toward the rollers," which press and roll it against the churn's sides.
This rung works out the pressing gap, then prints the arms, rollers and floats, assembles the dasher in a box, and makes and works butter.

"This operation is continued until the butter is gathered, when the milk may be drawn off at the bottom of the churn, by a faucet, pin or otherwise, and water may be added, and the butter washed, cleaned of the milk, and pressed, and rolled ready for use, thus performing the whole process of churning, gathering and working the butter without removing it from the churn."

Slide the arms onto a 10 mm square hardwood shaft 150 mm apart, set a roller's journals into each pair of end holes, and screw two pine strips edgewise between the arms as his angular braces. Hang each float on a 3 mm stainless rod through the arms' pin holes so it swings out to its shoulder one way and folds onto the roller the other.

Use a food-safe box about 230 × 190 × 200 mm with a curved liner of 0.5 mm stainless sheet bent to the rollers' circle plus a few millimetres, seated in silicone. Drill the ends on the axis, pass the shaft through with leather washers, glue on the crank arm and handle, and fit a plug low in one end to draw off the milk.

Let the heavy cream stand until it reaches about 15 °C, checked with the thermometer. Pour in 1.5 litres. Crank forward, floats out; time until the butter comes. Reverse the crank so the floats fold onto the rollers and the butter is pressed and rolled against the bottom. Draw off the buttermilk at the plug, add cold water and crank again until it runs clear; work in a pinch of salt the same way and weigh the butter.

History and honest limits
History and honest limits
**Davis Dutcher** of Springfield, Otsego County, New York, received US 8,143, dated 10 June 1851, antedated 15 February 1851. His crank's spindle fitted a square hole in the dasher's arm and was held by a latch in a groove, so it came out for cleaning; iron rods outside the box gave it strength. He claimed the arms with their rollers and the swinging arms with their floats, kept in place in churning and in gathering by the resistance of the cream.
**Honest limits.** A food-safe box with a stainless liner and printed parts stand in for his curved wooden box. FDM prints hold food in their layer lines, so wash well and replace when worn. Your times and weights are the result.
