To all whom it may concern

Be it known that I Rufus Maxwell of the county of Lewis and State of Virginia have invented a new and useful improvement in churns and I do hereby declare the following is a full clear and exact description of the construction and operation of the same reference being had to the annexed drawings making a part of this specification in which fig. 1 is a side elevation and fig. 2. is a side elevation of the rack

AAAA is a supporting frame inside of which the frame ccc is suspended by a hook and staple e. B is a churn fastened in the frame ccc at pleasure.

f is the handle being an extension of the top piece of the frame ccc and works vertically through a post of the supporting frame[.] d is a crank connecting the frame ccc with the supporting frame so that the centre of the bottom of the churn may revolve about a circle (five or six inches in diameter)

And this motion causes the milk to flow rapidly around the churn[.] Then I provide a rack for the purpose of breaking this current thus causing commotion and friction.

This rack consists of a piece of tough elastic wood bent as represented at fig 2 so that it will press against the sides of the churn thus holding the rack in a stationary position (with respect to the churn) There four pins are incerted in this bow at nnnn Parallel rods ii &c about one half an inch apart are fastened to these pins by boring holes through them and incerting the rods therein

I claim 1st The forcing of the milk through a rack by revolving the churn in an orbit without turning it on axis

2ly. The bow and rods connected togather as above described.
