Trapped-Air Cylinder Dash Churn: A Hollow Dash That Squeezes Air Into the Cream
Murdock wanted the air carried down through the cream by the common up-and-down dash itself.
Charles Murdock of Baltimore, Maryland, received US 6,133, dated 20 February 1849, for "Murdock's Atmospheric Churn": a hollow cylindrical dash, perforated round its lower open end, on the common dash staff, which is bored to slide over a fixed central spindle. The spindle stands in a stationary cylindrical block, smaller than the dash, held to the churn's bottom by a nut. At each stroke the dash fills with air above the cream, carries it down, and when it meets the block the air "is compressed in the cylinder forced radially through the apertures."
This rung works out the air squeezed out each stroke, then prints the dash and block, fits them to a churn, and makes butter.

"The air, however, may be let into the cylinder through a valve in its top or side instead of open end which will do away with the necessity of raising the cylinder above the surface of the cream to receive air. The aperture in the staff must be a little larger than the spindle but must not extend through it nor be intersected by any lateral opening."

Print the dash open end up (/uploads/blueprints/trapped-air-cylinder-dash-churn-dash.stl): a 90 mm cylinder with sixteen small holes near its open edge and a socket for the staff. Print the block (/uploads/blueprints/trapped-air-cylinder-dash-churn-block.stl). Print in PETG at 0.2 mm layers, 30 % infill, 4 walls; wash before first use.

Drill an 8 mm hole in the centre of a tall food-grade bucket's floor. Pass an M8 threaded rod up through it and the block, with a washer and nut under the floor and silicone round the hole, so the rod stands upright as the spindle.

Bore a 25 mm hardwood dowel lengthwise, 10 mm, deep enough to slide over the spindle's full height but not through its top, and glue the dash on its foot. Drill the lid for the staff and fit a knob on top.

Dash and make butter
Let the heavy cream stand until it reaches about 15 °C, checked with the thermometer. Pour in 1.5 litres. Work the staff up and down, lifting the dash above the cream each time to fill it with air; bubbles burst from the holes at the foot of each stroke. 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
**Charles Murdock** of Baltimore, Maryland, received US 6,133, dated 20 February 1849, signed 21 November 1848. The dash could be formed in the underside of the dash block, or as a cylinder fixed to the dash's periphery; in a stone churn the spindle's hole could be drilled and bushed. He claimed the combination of the hollow perforated cylinder dash and the central guide spindle and stationary block with the ordinary upright tub churn.
**Honest limits.** A bucket, threaded rod and printed parts stand in for his churn, spindle and dash. FDM prints hold food in their layer lines, so wash well and replace when worn. Your times and weights are the result.
