Funnel-Tube Cap-Plate Dasher: Streams Up the Funnels, Split by Wings, Thrown From a Cap

Sherman shaped his dasher so the cream is forced through it in streams on the way down and thrown off it in a sheet on the way up. Robert S. Sherman of Naponock, New York, received US 7,550, dated 6 August 1850, for a churn-dasher of a concave bottom plate with four or more inverted funnel-shaped tubes "projecting upward and outward" from openings in it, radial wings "whose outer edges are inclined upward and outward directly over the upper or smaller ends of the funnel shaped tubes," and a circular cap plate over the wings. On the descent the cream is forced up through the tubes "against the inclined edges of the radial wings" and thrown out "nearly horizontally against the sides of the churn tub." This rung works out the streams, then prints the dasher in one piece, fits it to a staff, and makes butter.
