Butterfly-Wing Churn: Two Dashers Hinged to an Adjustable Bar Flap Together From One Crank
Josiah Stubbs of Dublin, Indiana, received US 24,673, dated 5 July 1859, for a churn with two dashers hinged to a central bar like a butterfly's wings. The bar slides on notched stays inside the shell and is set so the cream barely covers it. One crank on the side works both dashers through two rods, one crossing the churn on a slant. Going down, the cream rushes round the dashers' edges against the shell; going up, flanges on the dashers carry cream up and throw it together.
This rung builds it in a 20-litre bucket.

Kelly flapped hinged dashers by swinging the tub. Stubbs keeps the shell still and flaps them from a crank.

"As the dashers are drawn upwardly, a portion of the fluid will be retained upon them, by means of the flanges (e) and thrown violently together as the dashers reach their upper extremity of motion".

Screw two hardwood stays a 24 x 15 mm, 337 mm long, upright inside the bucket on opposite sides, and saw notches a' 6 mm wide and 4 mm deep in their inner faces every 20 mm from 60 to 220 mm up. Cut a hardwood bar b 272 x 20 x 16 mm with a slotted block 44 mm wide at each end to slide on the stays, and fit an M5 set screw c with a wing nut through one block to hold it in a notch.

Cut two half-discs 244 mm across from 12 mm plywood and trim each to 220 mm along its straight edge. Glue the printed flanges e round their curved edges, standing 15 mm up. Hinge each dasher's straight edge to one side of the bar with two stainless butt hinges, 4 mm clear of the bar. Screw a small hardwood eye block on each dasher 100 mm out from the bar's middle, the right one 30 mm toward the front, the left one 40 mm toward the back.

Pour in about 8 litres of heavy cream at about 15 °C, checked with the thermometer, and set the bar in the notch the notebook gives so the cream barely covers it. Put the lid on and turn the crank steadily; time it. When the butter comes, lift the bar and dashers out, pour off the buttermilk, wash the butter in cold water until it runs clear, work in a pinch of salt and weigh it.

**Josiah Stubbs** of Dublin, Wayne County, Indiana, US 24,673, 5 July 1859, "Churn". He claimed working the butterfly wings with a single crank on one side, the rod g' crossing the cylinder on a slant. He gave no sizes or materials: every size, the notches' spacing and the crank's throw are ours.
