UNITED STATES PATENT OF ICE.

ROBERT H. KEERAN, OF CHILLIGOTHE, MISSOURI.

CHURbl.

SPECIFICATION forming part of Letters Patent No. 256,329, dated April 11, 1882.

Application filed September 30, 1881, (No model.)

T 0 all whom it may concern Be it known that I, ROBERT H. G. KEERAN, a citizen of the United States of America, residing at Ghillicothe, in the county of Livingston and State of Missouri, haveinvented certain new and useful Improvements in Ohurns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it-appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference'rnarked thereon, which form a part of This invention relates to improvement in churns; and the novelty consists in the construction of the attachments as will be hereinafter described and specifically claimed.

In the accompanying drawings, Figure l is a perspective view of my improved churn, showing the box in section to illustrate the dasher. Fig. 2 is a view of the same, showing the operating-gearing. Fig. 3 is a perspective view of the dasher, and Fig. etis a view of the dasher.

The letter A represents the frame, composed of a base-board with a depression to receive the base of the churn-box, the converging sides with transverse blocks near and at the upper ends, afi'ordi'ng bcarin gs and guides for the journals of the gearings and the dasher-rod, respectively.

The churn-box B is secured in position to the frame, and from upward (in fact from lateral) displacement also, by means of the transverse rod 0, passed over the churn and through the sides, substantially as shown, thereby keying down the churn-box firmly in place; At the upper end of the converging sides isarranged a transverse bar, D, extending forward over the churn-box, through which the upper end of the dasher-rod moves and is guided vertically. Between the converging sides, near the upper end,is arranged the blockE, affording a journal-bearing for the axle F, to which the crank-wheel H for operating the dasherrod is attached. To the other or rear end of the axle F is keyed or otherwise secured a pinion, I, engaging with a larger gear-wheel, K, suitably journaled to an axle secured to the rear side of the block E, substantially as seen in Fig. 2 ofthe drawings. This gear-wheel K, which serves also as a driving-wheel, is formed with two lugs or studs, b, between which is arranged the crank-handle L, made fast at its :55.

end by means of the screw 0. This wheel is provided with two or more holes in the arms for the adjustments. The inner end of the handle-(see Fig. 2) is made concave both longitudinally and transversely, so as to fit the convexity of the arms of the driving-wheel, and

by having the concave running in both directions a short or long leverage can be secured ened the dasher N, composed of two perfo-- rated bars, halved and crossed, and at a short distance above this dasherNis arranged a similar dasher, limited in its upward movements or vertical movements by a shoulder'or its equivalent. This dasher N has its perforations or' holes bored at an angle, so as to impart a rotary motion to the dasher as it is moved through the body of the cream.

The advantages of a churn constructed on this principle are obvious to those skilled in the art.

What I claim as my invention, and desire to secure by'Letters Patent, is-- In a churn, the combination of a driving gear-wheel provided with a plurality of adjusting-holes and steady-lugs b b, and an adjustable crank-lever arranged between the steadylugs and made fast to the said wheel by means of set-screws, substantially as described, and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

ROBERT H. G. KEERAN. Witnesses:

JAMES L. DAVIS, JAMEs E. CABLE.
