CHURN.
SPECIFICATION forming part of Letters Patent No. 374,753, dated December 13, 1887.
Serial No. 247,435. (No model.)
To aZZ whom it may concern:
Be it known that I, WILLIAM WALLAoE PERKINS, of Palouse, in the county of Whitman and Territory of \Vashington, have in vented a new and Improved Churn, of which the following is a full, clear, and exact description,
My invention relates to churns, and has for its object to provide a simple, inexpensive, durable, and efficient device of this character, which may be conveniently operated to bring the butter quickly and with economy of time and labor of attendants.
The invention consists in certain novel features of construction and combinations of parts of the churn, all as hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure I is a central vertical sectional ele-. ration of a churn made in accordance with my invention. Fig. 2 is a plan view of the rotatory dasher with its top removed, and Fig. 3 is an under side view of the dasher-top.
The cream-vessel A of the churn is preferablysnpported on the bottom of a box or frame, B, which has a recess, b, in which the vessel rests. The bottom of the vessel A is provided with a step-bearing, 0, in which is journaled the lower end of a shaft, 0, to which thecupshaped rotatory dasher D is attached. The side wall, d, of the dasher is nailed or other-. wise fastened at its upper edge to the dasher top or cover E, which rests on a collar, 0,
through a boss on the top against the shaft, holds. the dasher securely thereto. The creamvessel Ahas an inturned or overhanging brim or margin, a, which prevents overflow'of the cream, and the top opening of the vessel is large enough'toallow the dasher to be lowered into and raised from the cream-vessel, and the top of the dasher stands a little below the top of the cream-vessel, while the dashersides cl and its bottom (1 stand 0d from the side walls and bottom of the cream-vessel to provide a space, F, between the dasher and the vessel for circulation of cream during the churning process. 7
In the bottom of the dasher an opening, G, is made, and the dasher-body is provided with a radial wing, H, which preferably fits against the side of the dasher and extends inward to a point a short distance from the shaft 0, or about to the margin of the dasher-opening G. The wing H also fits the dasher-top E at the rear side or edge of a port, I, which is formed at or in the lower face and margin of the top, which is preferably, provided with a groove, h, to receive that part of the top of the wing H which projects radially inside of the port, aswill be understood from Figs. 1 and 3 of the drawings. The Wing H is practicallya piston or bucket, which, as the dasher rotates, backs up the cream and forces it outward through the port I into the cream-vessel A, as hereinafter more fully explained.
The dasher-shaft 0 extends up through and has a bearing in the top 12 of the box or frame B, and may be fitted with a crank to be turned in horizontal plane for rotating the dasher; but it may be preferable to provide the shaft with a bevel-pinion, J, to mesh with a bevel gear-wheel, K, fast to a short shaft, k, journaled in a bearing, L, fixed to the box B. Attached to the shaft is is a crank, M, for rapidly rotating the dasher by turning said crank. The box B may be substituted by a skeleton frame'of any kind, providing an upper bearing for the dasher-shaft.
The operation of the churn is as follows: After the cream is placed in the vessel A and the dasher is adjusted in the vessel, as shown in Fig. 1 of the drawings, the dasher will be rotated in a direction indicated by the arrow w in Fig. 3, and the wing or piston H of the dasherwill cause the cream, which enters the dasher through or at its lower opening, G, to be thrown around and carried upward and discharged through the port I against the whirling current of cream in the space, F, between the dasher and the side of the creamvessel, and a constant upward current of cream will pass from the vessel Ainto the dasher through its opening G, and will be forced by the wing H out again through the port I, to.
meet the whirling current of cream in the vessel which is induced by the rotation of the dasher in the cream.
It is obvious that the currents and meeting counter-currents of cream caused by the rapid rotation of the dasher will so thoroughly agitate the cream as to cause the butter to come quickly, thus assuring a complete and satisfactory churning with economy of time and labor.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination, in a churn, of a creamvcssel and a cup-shaped dasher journaled for rotation therein, and made' with a closed top, a bottom opening, a side port or outlet at or near the top, and a radial wing or piston operating, when the dasher is rotated, to force the cream admitted at the bottom of the dasher out through its upper port, substantially as herein set forth.

2. The combination, in a churn, of a creamvessel, A, a shaft, 0, stepped therein and jour' naled in an upper bearing, and a dasher, D, made with a top, E, provided with an upper port, I, a bottom opening, G, and a wing, H, set at the rear edge of the port I, substantially as described, for the purposes set forth.
3. The rotatable dasher, made open at the bottom and closed at the top, and provided with a fluid exit or port at or near the top, and a wing-piston set at the rear edge of the port, substantially as described, for the pur- 3c poses set forth.
