Buoyant Cone Dasher Churn: A Flanged Cone in a Cone, Pressed Down and Floating Back Up

Webber made the dasher the same shape as the churn, and let it float. Elbridge Webber of Gardiner, Kennebec County, Maine, received US 12,043, dated 5 December 1854, for a churn body "in the shape of an inverted cone" whose sides incline inward again above the base to a mouth closed by a perforated cover, and "a dasher of the same form having a projecting flange around the base of the cone," worked by a lever on a standard. Each downward stroke forces the cream up between the conical sides, "while the flange by intercepting its upward flow causes the current to be broken"; the dasher's buoyancy lifts it again. A pin frees the lever so the dasher can be drawn out. This rung works out the dasher's lift, then prints the two halves of the body, the cover and the sealed dasher, builds the frame and lever, and makes butter.
