Cone-Bowl Roller Butter Worker: Roll a Conical Stick Round a Conical Bowl, the Buttermilk Drains Below

Williams worked the buttermilk out of fresh butter by rolling a stick round a cone. I. M. Williams of Blanchester, Clinton County, Ohio, received US 12,366, dated 6 February 1855, for an "Improved Butter-Dresser": a round bowl of tin or wood "tapering from top to bottom, say top four times the diameter of bottom," with a small hole in its bottom bushed with bone, set in a rim with four legs and a brace; and a round working stick nearly filling the bottom, with a bone pin that nearly fills the hole. Rolled round the bowl, the stick presses the butter while the buttermilk sinks and escapes through the hole, "while the butter is pushed from the hole all the while." This rung works out the bowl's proportions, then prints the bowl, bush, roller, rim and brace, builds the stand, and dresses butter.
