CHURN.

SPECIFICATION forming part of Letters Patent No. 244,226, dated July 12, 1881.

' Application filed May 2, 1881. (No model.)

To all whom 'it may concern Be it known that I, JACOB GELHART, of Atwater, in the county of Portage and State of Ohio, have invented a new and useful Improvement in Rotary Ohurns and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,

forming .part of this specification, in which- Figure 1 is aside elevation. Fig. 2 is a vertical section on line 00 m, Fig. 1, and Fig. 3 is a horizontal section on line yy, Fig. 1. Fig. 4 is a top view of the churn -cover, showing the sections into which it is divided.

My invention relates to improvements in rotary churns; and it consists in certain details of construction, hereinafter more fully set forth.

In the accompanying drawings, a represents a stonejar, which constitutes the body of my improved rotary churn. The upper face of the bottom of the stonejar a is provided near its circumference with two opposite lugs or projections b 1), formed with the stone jar or churn-body, and adapted to fit into the recesses or notches c c in the opposite ends of a cross-bar, d, adapted to rest on the bottom of the stone jar, and provided near its ends with vertical arms a e, secured at their lower ends to the cross-bar d and at their upper ends to one of the sections of the cover of the churn, hereinafter described.

The dasher-shaft g is journaled at its lower end in the middle of the cross-bar d, and extends upward through a central orifice in the churn-cover, and is provided at its upper end with ajournal, h, having its bearing in a hole in a swinging plate or journal-bearing, i, having a hooked end,j, passing through a loop, k, in the upright l, secured at its lower end to the top face of the cover.

m represents a crank,provided withan axle, n, having its bearing in the upright, and provided at its outer end with a large wheel, 0, having cogs onits face, near its circumference, adapted to engage the horizontal pinion 19, secured to the dasher-shaft near its upper end.

The dasher consists of two horizontal arms, 9 g, passing through the dasher-shaft near its lower end, and secured thereto. The arms q q extend on each side of the dasher shaft the same distance, and are joined near their outer ends by the vertical pieces or beaters r r.

The churn-cover is separable and divided into two sections or parts, 8 1?, adapted to fit closely together to prevent the escape of milk in churning, and the line of separation passes through the central orifice of the cover through which the dasher-shaft passes. The section 8 of the churn-cover (see Fig. 4) is made larger than the other section, 15, and has its inner edge, o, concave, with projecting angular end a u. The object of this construction of the section 8, of the churn-cover is to provide enlargements u thereon, in which are mortised the upper ends, 0, of the recessed frame d c. The section 8 of the churn cover, though detachable from the churn body, is not ordinarily. removed therefrom, as it carries the operative mechanism of the dasher. It will be seen that by this construction the recessed frame d c is securely held in place at its lower end by the lugs in the bottom of the churn, and at its upper end by its arms 6, mortised in the enlargements a of the section 8, and that the dasher-shaft can readily be removed for cleaning or repairing it when broken, without displacing the recessed frame held securely in place, by simply removing the section tof the cover, throwing back the journalbearing, and removing the dasher-shaft from its bearing in the cross bar of the recessed frame.

I am aware thata swingingjournal-bearing has heretofore been employed in a churn and 1 am also aware that a dasher-frame has been held in position in a churn-body by means of lugs in the bottom of said churn-body; and I am further aware that a churn-cover has been made in sections, the line of junction of the sections passing through the central orifice of the cover, and I therefore lay no claim broadly to such constructions, my invention being confined to the peculiar arrangement and construction of the parts whereby the dashershaft c'an readily be detached from the churnbody without disturbing the other parts, as set forth.

What I claim as my invention is- The combination, with the churn body (I, provided with the lugs b, and churn cover composed of the section 8, having enlargements to u, and removable section if, of the recessed frame (I c, secured to the section .9 and churn-body, swinging journal-bearing i, and detachable dasher shaft g, substantially as described, and for the purpose set forth.
