Rack-and-Pinion Opposed-Dasher Churn: Two Rows of Hanging Dashers Move Opposite Ways Through Slots in the Lid
Nelson Gabel of Gratis, Ohio, received US 33,080, dated 20 August 1861, for a box churn worked by racks and a pinion. Two slides lie on the lid over two slots, each carrying three dashers that hang down into the cream. A rack on each slide meshes a pinion between them, so when a lever on a standard pushes one slide to and fro, the other moves the opposite way. The currents meet and break against each other and the box's ends.
The patent gives no sizes; every size here is ours.

Morgan's sliding frame spins beaters by a cord. Gabel's two slides carry the dashers themselves, and a pinion makes them move against each other.

"Thus it will be observed that when milk is put into the box and the lever (a) worked to and fro the agitation of the milk will be very great. As the currents each way will be broken and dashed in opposite directions the globules will thus be crushed both by sudden concussion against the side of the box and the violent reverse action of the currents."

Cut two hardwood slides h 560 x 50 x 25 mm and screw a rack b along the inner edge of each, teeth inward. Cut six 12 mm HDPE dashers 115 mm wide and 210 long; drill four 25 mm holes in four of them, the end ones. Screw each to a hardwood stem 20 x 20 mm, 90 long, and fix three stems under each slide, at its middle and 180 mm either side, to hang through the slot with the dashers 40 mm off the floor. Lay the slides on the top over the slots, racks facing.

Lift the top off with the slides and dashers, pour about 20 litres of heavy cream at about 15 °C, checked with the thermometer, into the box, and set the top back. Work the lever f to and fro through its full swing, timing it. When the butter comes, lift the top and dashers 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
**Nelson Gabel** of Gratis, Preble County, Ohio, US 33,080, 20 August 1861, "Churn". He claimed "the employment and arrangement of fixed pinion (a), double reciprocating racks (b b) and slides (h h)". His text calls the hand lever both (a) and (f). He gives the dashers only as drawn, three to a slide with holes in the end ones; ours are plain boards. The patent gives no sizes; every size here is ours.
