Rack-and-Pinion Rolling Beater Churn: Beaters That Turn One Way Up, the Other Way Down
Livingston wanted a deep, narrow churn in which every part of the cream is worked.
Norman B. Livingston of Portland, Indiana, received US 9,097, dated 6 July 1852, for a churn in which "a vertical rack (b) and groove (c) on each of two opposite sides of the box, receive pinions (d) on the two ends of a shaft (e) from which project wings or beaters (f)." A rod from a handle raises and lowers the shaft, and the beaters revolve "in one direction when going up and in the opposite direction when going down." He held a deep box made firmer, yellower butter than shallow vessels; that is his observation.
This rung works out the turn per stroke, then prints the wing hub, pinions and racks, fits them in a deep box, and makes butter.

"The motion of the handle up and down, causes the shaft (e) and beaters (f), to ascend and descend in the groove (c), and the pinions (d) working at the same time in the racks (b), the beaters are thereby caused to revolve in one direction when going up and in the opposite direction when going down, so that both the vertical and the rotary movements, are reversed at every stroke."

Pass a 10 mm square hardwood shaft through the hub and fix a pinion on each end so each meshes its rack, the shaft's ends riding in the grooves. Pivot a steel rod on the shaft's middle, and its top on a pine hand lever pivoted on a post at the box's end.

Work the lever and make butter
Let the heavy cream stand until it reaches about 15 °C, checked with the thermometer. Pour in 2 litres. Work the lever up and down; the beaters roll one way and back. Time until the butter comes. 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
**Norman B. Livingston** of Portland, Fountain County, Indiana, received US 9,097, dated 6 July 1852. He claimed the racks, grooves and pinions by which the shaft and beaters traverse the cream with a compound vertical revolving and reciprocating motion.
**Honest limits.** A food-safe box and printed gears stand in for his. FDM prints hold food in their layer lines, so wash well and replace when worn. Your times and weights are the result.
