Spiral-Wing Spheroid Churn: A Ball Dasher on Balls Turns Freely on Its Rod, Its Spiral Wings Spinning It Each Stroke

Otis W. Stanford of Cincinnati received US 28,696, dated 12 June 1860, for a churn. On the foot of an ordinary up-and-down dash rod he hangs a round or egg-shaped wooden dasher that turns freely on balls, with spiral wings nearly touching the tub's sides. As the rod is worked, the cream spins the dasher one way then the other; the cream is squeezed between the wings and the wall, and air trapped under the round body is carried into it. The patent gives no sizes; every size here is ours.

A dash that turns as it is driven, one week before

Ross's pitched blades turn the dash and handle on a swivel. Stanford's spiral wings turn the dasher alone, on balls.

Read US 28,696

"The rod C being reciprocated, as in the common churn, the inertia of the fluid acts to swiftly rotate the dasher in successively opposite directions and this reacting upon the liquid imparts to the latter a quick succession of opposite vertical movements resulting in violent agitation."

Rod C, dasher D, balls G, screw E and washer F

Cut a 25 mm hardwood rod 500 mm long and glue a 12 mm stainless spindle 170 mm long into its foot. Glue the two printed halves together with the wings lined up. Slide on a ring of 6 mm stainless balls in the upper recess, the dasher, and a second ring in the lower recess, and hold them with a stainless washer and a machine screw into the spindle's end. The dasher must spin freely.

Churn

Pour about 6 litres of heavy cream at about 15 °C, checked with the thermometer, into the bucket, set the dasher in and put on the lid over the rod. Work the rod up and down about 150 mm, steadily, timing it; the dasher turns one way and back. When the butter comes, lift the lid and dasher out, take out the 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

**Otis W. Stanford** of Cincinnati, Hamilton County, Ohio, US 28,696, 12 June 1860, "Churn". He claimed the upright tub with the reciprocating rod, the spheroidal dasher and spiral wings fitting the tub. His dasher is wooden; ours is printed in two halves, and the wings' number, twist and every size are ours.
