Twin-Crank Slide-Top Churn: Two Dashers on a Bent Crank Shaft, Sliding Plates Keep the Milk In
Cable L. Gilpatrick of Saco, Maine, received US 25,405, dated 13 September 1859, for a churn. A crank shaft bent into two opposite cranks rides on two posts above a box and works two dashers, so one goes down as the other comes up. Each dasher is two boards crossed and bored with holes. The staffs pass through holes in two slides that move in casings on the top, following the staffs so the milk cannot splash out.
The patent gives no sizes; every size here is ours.

"Motion is then communicated to the dashers by means of the crank-shaft. As one dasher descends, the other ascends. Thus the milk is kept in contant agitation, which is necessary in order to churn expeditiously. The slides being operated upon by the dasher-staffs prevents the milk from splashing out, as it otherwise would do."

Box A and its posts
Box A and its posts
From 20 mm hardwood make a box 400 x 360 mm and 450 mm deep inside, with a bottom. Make the two 400 mm sides 170 mm taller, narrowed to posts 120 mm wide above the box, and bore each post 13 mm, 600 mm above the bottom's underside, for the shaft. Glue and screw a cleat 20 mm square along the inside of each post side, 30 mm below the rim, for the top. Fill the box with water overnight so it swells tight, then empty it.

Crank shaft D and crank E
Crank shaft D and crank E
Cut 12 mm stainless rod about 750 mm long. Heat each bend red with the torch and bend it in the vise into two cranks of 50 mm throw, pointing opposite ways, each crank pin 50 mm long, their middles 180 mm apart. Check the journals line up by rolling the shaft on the bench. Thread one end through a post, the collars' lower halves onto the pins, and the other end through the other post. Fix a hardwood crank E, 160 mm long with a handle, on the end that sticks out.

Top A', casings F and slides H
Top A', casings F and slides H
Cut the top to drop onto the cleats, with two slots 140 x 50 mm across it, under the cranks, and a finger hole. Over each slot build a casing F: two rails 20 x 26 mm, 370 mm long, 80 mm apart, with a strip on each that overhangs the inside by 8 mm, and an end block at each end, leaving 346 mm inside. Cut each slide H 240 x 79 mm from 18 mm hardwood, so it slides under the strips, with a hole 34 mm square in its middle, 4 mm bigger than the staff.

Staffs B and dashers C
Cut two staffs 30 mm square, 480 mm long. For each dasher, half-lap two boards 180 x 50 x 15 mm into a cross, bore eight 12 mm holes, cut a 30 mm square hole in the middle, and glue the staff's end into it. Set the top on its cleats, pass each staff up through its slide's hole, and bolt the collar's cap over its pin and onto the staff's top, turning the cross so its arms point to the box's corners.

FreeCAD model of this build, one side and the lower part of one post cut away: the box, the bent crank shaft on its posts with crank E, the two staffs in their collars, the dashers, and the slides in their casings on the top. The crank was turned through 24 positions.

Lift the collars' caps off, take out the top, pour in about 15 litres of heavy cream at about 15 °C, checked with the thermometer, and put the top and caps back. Turn the crank steadily, timing it. When the butter comes, take the top out, lift out the butter, drain 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
History and honest limits
**Cable L. Gilpatrick** of Saco, Maine, US 25,405, 13 September 1859, "Churn". He claimed the crank shaft D and staffs B with the top A', "when said top is provided with boxes (F,) in which play slides, through which the staffs pass". The patent gives no sizes; every size here is ours. His collars are not described beyond "passing around said cranks"; ours are printed and split so the top can come out.
