Description

UNITED STATES PATENT OFFICE.

V. STIREWVATT, OF ALBANY, GEORGIA.

CHURN.

Specification of Letters Patent No. 31,413, dated February 12, 1861.

To all whom it may concern:

Be it known that I, V. STIREWATT, of Albany, in the county of Dougherty and State of Georgia, have invented an Improved Churn; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

Figure l is a side elevation of the churn, the lower portion of the churn body being in section, to show the dasher, and inner arrangement, of the churn; Fig. 2, a plan of the churn body, the driving gear and cover being removed; Fig. 3, a central vertical section of the churn body, in the plane indicated by the line 00 m, Fig. 2, the dasher being removed.

Like letters designate corresponding parts in all the figures.

A vessel A, nearly or exactly cylindrical, is employed for the churn body. Upon the inner side of this vessel, cleats, or ribs, L, L, are secured vertically, at suitable intervals, as shown in the drawings. These cleats serve to arrest the motion of the cream caused by the revolutions of the dasher H, to break the butter globules and cause eddies of the cream in the spaces between, thus increasing its agitation and causing more or less air to be mingled therewith. To give a greater effect to the action of these ribs, or cleats, they are interrupted by notches or spaces m, m, as seen most clearly in Fig. 3, the positions of those in the adjacent ribs alternating as represented. That is, the spaces in one rib, are horizontally opposite to the projecting portions of the adjacent ribs. These notches, or spaces, may reach the entire depth of the ribs, as shown at the right-hand side in Fig. 3, or only a part of their depth, as seen at the left hand side in the same figure. The ribs, or cleats, are secured to the churn body A, by screws Z, Z, or their equivalents. The action of these alternately placed spaces and rib projections is such that the cream is forced, in intermingling and crossing currents, around filling the churn body between the ribs, and

substantially of the shape shown in Fig. 2; that is, with curved wings, which being driven in the usual direction, forces the cream more strongly outward, but being driven in the other direction, diminishes the centrifugal action and renders easier the gathering of the butter. The shaft f, of the dasher rests in a bearing 2', in the bottom of the churn body; while its upper end h, is angular, and fits in a corresponding socket g, on the end of the pinion shaft d. The pinion E, on the shaft d, is turned by the driving wheel D, to which a crank or winch G, imparts the power. The whole driving gear is mounted in a standard C, and cross piece B, which is fastened upon the churn body by fitting over two upwardly project ing ears, or studs a, a, secured to opposite sides of the churn body, as represented; and passing pins Z), 5, through all, or by some equivalent device, so that the whole driving gear may be readily removed, and placed on, again, as occasion requires. A suitable cover I, is also placed over the churn body.

What I claim as my invention and desire to secure by Letters Patent, is

The ribs, or cleats, L, L, on the inner surface of the churn body A, arranged and operating in combination with the dasher H, substantially as and for the purpose herein specified.

In witness that the above is a true specification of my improved churn, I hereunto set 0 my hand this 4th day of September, 1860.

V. STIREVVATT.

GEORGE MAGAULEY, A. I. MAOARTHY.
