Rubber-Pipe Pump Churn: A Pulley Rolls Milk Through a Tube in a Ring and Jets It Through Gauze

Loren J. Wicks of Racine, Wisconsin, received US 24,686, dated 5 July 1859, for a churn that is a rolling-tube pump. An india-rubber pipe runs from the bottom of the milk box once round the groove inside a ring and up into a smaller box on top. A pulley on a fast crank rolls round the ring on the pipe and drives the milk up in a stream against two gauze partitions hung under the top box's cap. The broken milk runs back through a screen of fine wooden strips into the box below, the butter staying behind; the stream keeps going until all the butter is out. This rung builds it with silicone tubing, a printed ring and pulley, and pine boxes.

"Thus it will plainly be seen that in the manner which pipe (B) passes round circular frame (F) the pulley when rolling on it will force the milk up into box (C)."

Stand and boxes

From pine make box A 360 x 240 mm inside and 230 mm deep, and stand it on four 44 mm legs 400 mm tall. Drill a 13 mm hole near the front of its floor. Make box C 360 x 122 mm inside and 180 mm deep, with a floor, and stand it on two cleats across A's back, leaving A open for 100 mm in front of it. Cut C's front out between 18 and 122 mm up and glue hardwood strips 6 mm wide upright in the opening, 4 mm apart, as screen D. Drill C's front 13 mm above the screen for a 8 mm stainless spout.

Cap I and partitions E

Cut a plywood cap 340 x 100 mm to slide on C's top. Make two frames 240 x 138 mm from 3 mm plywood with a window in each, staple stainless mesh over the windows (for his tin and gauze), and screw them upright under the cap 40 mm apart, across the jet's path.

Frame F, pulley and pipe B

Screw a pine board across the front legs below box A and screw the printed frame F on its front, 220 mm up. Bore the board for a 12 mm stainless shaft G with a hardwood support K behind it, fit the rotor and pulley H on its pin inside the frame and a hardwood crank P outside. Push 12 x 8 mm silicone tubing into A's floor hole, sealed, down through a hole in the board and the hole in F's foot, once round the groove, out through the same hole, round the outside of F and up to C's spout.

The build in 3D

FreeCAD model of this build, half the boxes cut away: box A on its stand, box C with screen D, the cap and the two mesh partitions, the board with frame F, the rotor and pulley on the shaft, the crank, and the tube's run from A's floor round the ring and up to C. The rotor was checked at six angles.

Churn

Pour about 10 litres of cream at about 15 °C into box A, checked with the thermometer. Turn the crank fast and time it: a stream jets into C against the mesh and runs back through the screen. Slide the cap back and forth now and then. When the butter is held in C, stop, lift C off, take the butter out, pour the buttermilk from A, wash the butter in cold water until it runs clear, work in a pinch of salt and weigh it.

History and honest limits

**Loren J. Wicks** of Racine, Wisconsin, US 24,686, 5 July 1859, "Churn". He did not claim forcing milk in a stream against a substance as such, only boxes A and C with pipe B, and box C with screen D and the hanging partitions E. His pipe was india rubber and his partitions tin and gauze; our silicone tubing, mesh frames, printed ring and pulley and every size are ours.
