Four-Crank Gyrating Churn: Four Cranks Carry the Tub Round a Small Circle With No Dasher

Alfred Guthrie of Chicago received US 24,907, dated 26 July 1859, for a churn with no dasher at all. Four upright shafts in a frame have cranks on their tops, and a bed plate lies over the four crank pins, so each crank turns on its own centre but all move together. The tub stands on the plate, held by stirrups, and is carried round a small circle, throwing the cream against its sides. A handle turns one crank shaft through cogged gearing. This rung builds it at the patent's own sizes: a frame about two feet square and one foot high, shafts of 3/4 inch iron and 3 inch cranks.

A churn with a dasher, before it

Wineman's dasher drove the cream through holes. Guthrie did away with the dasher and moved the whole tub.

Read US 24,907

"I connect the whole together by the bed plate D over the wrists of each crank E, E, E, E. Each crank will revolve upon its own center but will each correspond to the motion of the other."

Frame and bearing bars

Build a pine frame 610 mm square and 305 mm high: four 50 mm corner posts, and 50 mm rails round the top and the bottom. Fit two hardwood bars across it, top and bottom, 150 mm in front of and behind the middle, and bore them 19.6 mm square to the frame at 200 mm either side of the middle, for the four shafts. Screw two hardwood brackets to the right side, top and bottom, bored 20.6 mm 132 mm out from the front right shaft, for the handle shaft.

Shafts, cranks and plate D

Cut four 19 mm steel shafts 323 mm long and stand them in the bars. Make four hardwood crank arms, 76 mm from the shaft to the crank pin, and pin them on the shafts' tops all pointing the same way. Fit a 19 mm steel crank pin 50 mm long in each. Cut plate D 532 mm across from plywood, bore it for the four pins exactly where they stand, and drop it on them. Turn one crank by hand: the plate must run round freely without turning.

Tub F on its grooved bottom

Glue a plywood ring to the plate's middle, 282 mm inside and 340 mm outside, so the bucket's foot sits in it. Bend two flat-bar stirrups to go up the bucket's sides and over its lid, notch the ring for them and bolt them to the plate.

Churn

Pour about 8 litres of heavy cream at about 15 °C into the bucket, checked with the thermometer, put the lid on and tighten the stirrups. Turn the handle steadily and time it. When the butter comes, lift the bucket off, pour off 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

**Alfred Guthrie** of Chicago, Illinois, assignor to Wardell Guthrie, US 24,907, 26 July 1859, "Churn". He claimed the cranks C connected by the plate D. His sizes are kept: a frame about two feet square and one foot high, shafts of 3/4 inch iron about a foot long, and cranks of 3 inches, which we read from "about a six inch throw or three inches" and Fig. 3's "3 in" marks. He gives no gear sizes; ours are printed spur gears placed as his Figs. 2-3 draw them. Every other size is ours.
