Liftable-Breaker Dasher Churn: Breakers Stand Still to Churn, Then Lift and Turn to Gather

Dickinson made the breakers do two jobs: stand still while the cream is churned, then turn with the dashers to gather the butter. Isaac L. Dickinson of Richmond, Wayne County, Indiana, received US 10,487, dated 31 January 1854, for "Dickinson's Improved Churn": perforated dashers on a shaft turned by a crank through bevel wheels, between perforated breakers joined by arms through which the shaft passes, "held stationary by pins entering holes in the bottom of the tub." When the butter is separated the breakers are lifted; the dashers' lower ends enter slots in them, held by small springs, and both "revolve together" to collect the butter. An oblique hole through the shaft admits air. This rung works out the speeds, then prints the base plate, breaker frame, dasher, crown wheel, pinion and standard, builds the churn, and makes butter.
