Braked-Disk Slat-and-Wing Churn: Up Between the Slats, Down Through the Disk

Wade sent the cream round a loop: up the sides and down through the middle. Isaac M. Wade of Clinton, Lenawee County, Michigan, received US 13,133, dated 26 June 1855, for a churn with radial wings on the foot of a vertical shaft, turned through bevel wheels by a crank; vertical slats round the inside of the tub that the wings just clear; and on the slats' shoulders a disk with a central aperture and four brakes, "flat wooden strips secured edgewise on the disk," placed tangent to the aperture and held still by a pin. The wings force the cream "upward between the slats (f) and thrown against the brakes A¹, which direct it to the aperture (g)," and the slats and brakes "prevent the cream from rotating." This rung compares the openings, then prints the slats, the disk with its brakes, the wings, step and gears, builds the churn, and makes butter.
