Bellows-and-Float Atmospheric Churn: Blasts of Air Through a Water-Jointed Pipe, a Float Gathers the Butter
Patrick S. Devlan of Reading, Pennsylvania, received US 24,382, dated 14 June 1859, for a churn worked by blasts of air only. A bellows under the body, worked by a lever, blows up a pipe that opens inside a wider tube; the air goes down between them and out through a perforated disk across the bottom, so it is spread through the whole cream. The cream standing in the tube makes a water joint, so no valves are needed. A perforated float with projections rides up and down on the bubbling cream and gathers the butter as it forms.
This rung builds it with a 20-litre bucket on legs and a bellows below.

Wicks drew air in with turning funnels and a dasher. Devlan blows it in with a bellows and has no dasher at all.

"... this pipe or tube, C, is open at its upper end, but is entirely surrounded to within a short distance of its base by another tube D, of greater diameter which tube D, is connected at its base to the center of the convex perforated disk d."

Pipe C, tube D and disk d
Drill the middle of the bucket's floor 16.5 mm and seal a 16 mm stainless pipe C through it with silicone so it stands 400 mm up. Drill 24 holes of 4 mm in two rings in a stainless bowl about 260 mm across and a 32.5 mm hole in its middle, and stand it upside down on the floor round the pipe as disk d. Push a 32 mm stainless tube D 360 mm long through the printed collar into the bowl's middle hole, sealed with silicone, so it surrounds pipe C down to 56 mm above the floor. Run silicone tubing from the bellows' nozzle to pipe C's foot under the floor.

Cut a 45 mm hole in the middle of the bucket's lid and glue the teat e over it, with its cap f. Cut float G from 15 mm plywood, 250 mm across with a 48 mm hole for tube D and eight 22 mm holes, and glue 10 mm dowel pegs 25 mm long into both faces as the projections g. Bolt a hardwood lever b to the outside of one leg 360 mm up, running up beside the bucket to a handle c above the lid, and join it to the bellows' top board with a hardwood link.

FreeCAD model of this build, the near half of the body cut away: the stand with its seat, band and shelf, the bellows and hose, pipe C inside tube D, the drilled bowl as disk d, the float with its pegs, the lid with its teat and cover, and the lever with its link.

Fill the bucket about one third full: about 6.5 litres of heavy cream at about 15 °C, checked with the thermometer. Drop the float in over tube D and put the lid on. Work the lever steadily and time it: each stroke blows a burst of air up the pipe, down the tube and out through the bowl's holes. When the butter has gathered on the float, lift it out, pour off the buttermilk, wash the butter in cold water until it runs clear, work in a pinch of salt and weigh it.

History and honest limits
**Patrick S. Devlan** of Reading, Berks County, Pennsylvania (the drawing spells it Devlen), US 24,382, 14 June 1859. Earlier blast churns, he wrote, blew the air in one place, needed valves and did not collect the butter; he claimed the float in a churn worked by blast only. His only quantity is "say one third full". His pipe C rises straight from the bellows and his disk d spans the floor; our hose, drilled bowl, pegs and every size are ours.
