IMPROVEMENT IN GHURNS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, \VILLIAM DAVIS, of Arrow Rock, in the county of Saline, and State of Missouri, have invented a new and useful Improvement in Automatic Churns; and I do hereby declare that the.following isa full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. p i

Figure 1 of the accompanyingdrawings is a transverse sectional elevation of one of the improved churns.

Figure 2 is a sectional side elevation of it. I

This invention relates, firstly, to the construction of the churn, with reference to the vessel for containing the milk, and also of the dashers for agitating it; and secondly, to the manner of applying a spring or weight attachment to clock-gearing, for the purpose of operating the dashers.

To'enable those skilled in the art to make anduse my invention, I will proceed to describe its construction and operatiom.

A A is the vessel .for containing the milk to be operated upon. It should be formed somewhat in the form of a barrel with two heads, connected with staving, the contour of which may be circular, or octagonal, as in the drawings. Thereis a frame, B, attached to one end of the part A, for'the purpose of sustaining the shafts a and b. The part of the vessel A is a lid, hinged; to the part A by means'of the hinges c, and secured with the hook c. The shaft a is located between the parts A and A, so that when the lid is open the shaft may easily beraised up out of the churn, for the purpose of cleansing the parts. The dashers consist of two end pieces D, connected together by means of the diamond-shaped rods D. The latter are made in that shape, as experiment has proven it to be the best. The shaft a should be arranged to slip easily through the dash'erheads D, so that the whole may be taken apart for washing. There is a small cog-wheel, a, on the outer end of the shaft a, which gears into a cog wheel, 6, on the shaft 6. There is also a spring and ratchet on the shaft b, so it may be wound'up like a clock, by means of a crank on the outside, and then, like a clock, it will run down, thereby turning the wheels and the dasher, and thus produce butter.

It is very evident that a weight might be substituted for a spring to produce the required power.

Having described my invention, what I claim as my improvement, and desire to secure by Letters latent, is-

The disks D, shaft a, diamondshaped heaters D, gears a b, and spring B, in combination with the case A A, all the parts being constructed, combined, and arranged as and for the purpose specified.

WM. DAVIS.
