Interlapping Spiral-Dasher Churn: Two Upright Shafts With Arms Set in Screw Form Interlap, One Turning the Other

D. M. Woodin of Brandon, Wisconsin, received US 28,528, dated 29 May 1860, for a churn. Two shafts stand side by side in a box, each with arms set round it in a screw form; the arms of one pass between the arms of the other, so turning one shaft with the crank turns the second "like spiral gearing". The two screws force the cream down between them and it rises again outside, while the arms meet and close on each other, breaking the globules. The patent gives no sizes; every size here is ours.

Vaughan joins his two dashers with pinions. Woodin lets the dashers' own arms drive one another.

Read US 28,528

"These two spiral wheels revolving in this way force the cream downward all the while, but it rising again on the outside of the wheels, is kept moving in a constant current from top to bottom, and from bottom to top. In addition to the friction thus caused and the moving of the cream in a constant current, the arms overlapping and interlapping mash the globules of the cream as they meet and press against each other."

Box A and steps

From 20 mm hardwood board make a box 350 x 220 mm inside and 350 deep; glue and screw it and seal the inside joints with silicone sealant. Screw two hardwood blocks 50 x 50 x 10 mm to the floor on the long centre line, 128 mm apart, the first 110 mm from one end, each bored 16.6 mm, 6 deep, as steps. Cut a lid to sit on top, bored 17 mm over each step.

Wheels B, B with spiral arms a

For each wheel cut fourteen hardwood bars 190 x 30 x 20 mm and halve them together in pairs into seven crosses, each bored 16.2 mm at the crossing. Thread the crosses onto a 16 mm stainless shaft, 40 mm apart centre to centre from 40 mm above the floor, each turned 22.5 degrees from the one below, checked with the protractor, and pin each through. Turn the second wheel's crosses the opposite way, so its spiral is of the other hand. The driven shaft is 425 mm long, the other 375.

Set the wheels and the gearing

Stand both shafts in their steps and turn the second so its arms sit 45 degrees between the first's at every level; they must pass each other about 5 mm apart all the way round. Put on the lid. On the driven shaft's top fit the pinion; on the lid screw two hardwood chairs carrying a 12 mm stainless crank shaft with the crown wheel meshing it, and a hardwood crank with a dowel handle. Hold the shafts with collars.

Churn

Pour about 10 litres of heavy cream at about 15 °C, checked with the thermometer, into the box, put the lid and gearing on, and turn the crank steadily, timing it, the way that drives the cream down between the wheels. When the butter comes, lift off the lid and the wheels, take out the butter, tip the buttermilk into a bowl, wash the butter in cold water until it runs clear, salt and weigh it.

History and honest limits

**D. M. Woodin** of Brandon, Fond du Lac County, Wisconsin, US 28,528, 29 May 1860, "Churn". He claimed the two dasher shafts with wings in screw form, one turned by the other. He does not give the number of arms or how far each turns on; our seven stations of four arms, 22.5 degrees apart, and the spacing are ours, as are the printed crown wheel and pinion that stand in for his bevel wheels.
