Window-Blind Dasher Churn: Slats Set Slantwise Through the Staff, Turned Back and Forth by a Cord From a Swinging Disk

Samuel A. Kerr of Arbor Hill, Virginia, received US 28,757, dated 19 June 1860, for a churn. Flat slats pass slantwise through an upright staff, one above another like the slats of a window blind. A cord from a disk swung back and forth by a handle turns the staff to and fro: the slats on one side throw the cream up, those on the other throw it down, and it passes between them from side to side. Turned gently, the overlapping slats gather the butter. A funnel in the lid lets air in. The patent gives no sizes; every size here is ours.

Read US 28,757

"By this oblique arrangement of the blades or slats on a vibrating or turning dasher staff, the cream or milk will, when the staff is rapidly vibrating, be thrown downward, on one side of the staff, and upward, on the other side, at each back or forward movement; and it also will be caused to pass between the slats from one side of the churn to the other."

Dasher C: staff and slats a

Cut a 35 mm square hardwood staff 340 mm long and glue 12 mm stainless spindles into its ends. Cut five hardwood slats 240 x 60 x 8 mm and drill each with four 12 mm holes. Chisel five slots through the staff, each at 45 degrees to it and 45 mm apart from 80 mm above its foot, all sloping the same way, and glue the slats through them, centred, so each slat's lower edge meets the next one's upper edge.

Turn or cut a hardwood pulley 60 mm across with a groove and fix it on the staff's top spindle above the bar. Cut a hardwood disk E 200 mm across with a groove round its edge, pivot it on a 12 mm stainless pin in the bar's end, and screw a hardwood handle F with an upright dowel grip across it. Tie a cord to the disk, take it round the pulley once and back to the disk, and tie it tight.

Churn

Pour about 8 litres of heavy cream at about 15 °C, checked with the thermometer, into the bucket, set the dasher in its step, put on the lid and bar, and swing the handle quickly back and forth, timing it. When the butter comes, swing it slowly and gently to gather it, as the patent says. Lift off the bar and lid, take out the dasher and butter, pour the buttermilk into a bowl, wash the butter in cold water until it runs clear, salt and weigh it.

History and honest limits

**Samuel A. Kerr** of Arbor Hill, Augusta County, Virginia, US 28,757, 19 June 1860 (signed 9 May 1860), "Churn". He claimed only the manner of arranging the slats on a vibrating or turning staff, not the means of vibrating it. He allows solid or perforated slats and a cord or chain; our slat count, angle and sizes are ours.
