Three-Series Beater Churn: Outer and Inner Loops Turn One Way, the Middle Loops and Centre Blades the Other

Simon G. Cheever of Boston received US 28,560, dated 5 June 1860, for a machine for mixing paints, oils and powders that "may also be used as a butter mill or churn". Three nested series of loop beaters hang on one shaft: the outer and inner series turn one way and the middle series the other, while curved blades at the centre throw the cream outward into them. One crank drives it all through a wheel with a pinion on each side. This builds it as a churn. The patent gives no sizes; every size here is ours.

Nested dashers driven by one wheel and two pinions, seven weeks before

Dunham and Hipple nest two frames. Cheever nests three, the middle one turning against the other two.

Read US 28,560

"... the arrangement of the pinions on opposite sides of the driving wheel, and their connections through the collars with the outer and inner series of beaters or mixers, and the action of the central curved blades, is to throw the material constantly from the center to the circumference and there to submit it to the opposing forces of the beaters revolving in opposite directions."

Outer and inner series I, I on collars G and H2

Bend 6 mm stainless rod into two outer loops 220 mm across and 300 tall and two inner loops 120 across and 220 tall, open at the middle of top and bottom. Cut 130 mm of 18 mm stainless tube as the sleeve of collar G and fix two printed or hardwood hubs 32 mm across on it, 40 mm apart; screw the outer loops' top ends to the upper hub and the inner loops' to the lower, crossed at right angles. Screw their bottom ends to two hubs H2 bored 12.6 mm, which turn free on the shaft.

Middle series h, collars H and G2, blades L and M

Bend two middle loops 170 mm across and 260 tall. Screw their top ends to a ring H 44 mm across, bored 18.6 mm, that rides on the sleeve between G's two hubs, and their bottom ends to a hub G2 pinned to the shaft F between the two H2 hubs, set 45 degrees from the outer loops. Pin two curved printed blades, 180 tall and reaching 50 mm, on the shaft inside the inner loops.

Shaft F, bridge, arm A, wheel C and crank K

Pass a 12 mm stainless shaft F, 500 mm long, up through G2, H2 and the sleeve. Cut a hardwood bridge 350 x 330 x 15 mm to lie on the bucket's rim, bored 24 mm in the middle for the sleeve. Fix the pinion E on the sleeve's top, and the pinion D on the shaft above it. Screw two hardwood arms to the bridge carrying a 12 mm stainless axle with the wheel C meshing E below and D above, and a crank K on its end; a hardwood bracket over D holds the shaft's top.

Churn

Pour about 8 litres of heavy cream at about 15 °C, checked with the thermometer, into the bucket, lower the beaters in and set the bridge on the rim. Turn the crank steadily, timing it. When the butter comes, lift the bridge and beaters 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

**Simon G. Cheever** of Boston, US 28,560, 5 June 1860, "Machine for Mixing Paints". He did not claim opposed pinions on one wheel, nor mixers or churn dashers turning oppositely, but the arrangement of the collars so the middle series turns against the outer and inner, with the central curved blades. His arm is metal and clamps into a dovetail socket on any bench; ours is hardwood on a bridge across the bucket. He leaves the number and shape of the beaters open; our loops, counts and every size are ours.
