CHURN.

u Applicationv filed August 4, 1921. Serial No.,489, 800.

To all whom it may concern:

Be it known that, I, J HN P. DONALDSON, a citizen of the United States, residingat in thecounty of Wood and State of Texas, I have invented certain new and useful Improvements in Churns, of which the following is a specification.

This invention relates to churns and more particularly to closures therefor.

The objectofthe invention is to construct a churn having a gravity closing lid, which of its own weight automatically effects a tight fit to prevent the milk from being thrown out in churning.

Another object is to provide a churn equipped with means to facilitate handling and emptying of the churn.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown, described and claimed.

In the accompanying drawings:

Figure 1 represents a side elevation of a chu'rn constructed in accordance with this invention; and

Fig. 2 is a similar view taken in a plane at right angles to Fig. 1. with parts broken out and in section.

In the embodiment illustrated, the churn body or barrel 1, and its closure 10 are preferably constructed of earthenware. The churn body or barrel 1, is substantially cylindrical in contour, and has its outer face, near its lower end, provided with an integral lengthwise extending and laterally projecting boss 2, which gradually increases in thickness from its upper toward its lower end, and near its lower end, is provided with a transverse opening, in which is mounted a hand grip 3, somewhat in the form of an oval shape loop, and which is provided to facilitate the pouring of the contents of the churn body or barrel 1, or for otherwise handling the latter.

The inner face of the churn body or barrel 1, at its upper end, has an integral enlargement throughout, and which extends inwardly with respect to the innerface of the churn body or barrel 1, and provides an inwardly extending annular flange 6, and which is of a thickness greater than the thickness of the wall of the churn body or barrel 1. The flange 6, gradually increases in width from its upper to its lower face, whereby the inner edge oiinner side face of the flangev will incline downwardly and inwardly forming a seat 4, which is beveled throughout, and which is arranged inwardly with respect to the inner face ofthe churn body or barrel 1. The upper face of vthe flange 6 is flat and is flush with the top of the outer face of the churn body or barrel 1, and the lower face of the flange 6 inclines upwardly and inwardly.

Supported by the seat 4, is a closure or lid 10, which has its edge 11, inclining downwardly and inwardly from the outer face of the closure or lid 10, to the inner face thereof, as clearly shown in Figure 2,

whereby the closure or lid 10, will gradually decrease in diameter from its outer to its inner face. The thickness of the lid 10 is materially less than the thickness of the flange 6, and the inclination of the edge 11, of the closure or lid 10, corresponds to the inclination of the seat 4. The diameter of the closu're or lid 10, with respect to the inner diameter of the flange 6, is such as to cause the closure or lid 10, to automatically shift by gravity down the seat, so that when the closure or lid 10, is mounted against the seat 4, the weight of the closure or lid 10, will cause it to automatically move down on the seat 4, and effect a tight fit, so that all possibility of the contents of the churn body or barrel 1, from being thrown out between the closu're or lid 10, and the flange 6, is prevented.

From the foregoing, it is obvious, that a wedge fit is set up between the closure or lid 10 and the seat 4, and that such wedge fit is unlimited, so as to compensate for wear between the edge 11 and the seat 4, as well as overcoming any loose motion and rattling of the closure, during the churning operation.

The closure or lid 10, is provided with a vertically disposed aperture 12, as indicated in dotted lines, Figure 2, for the passage of the churn dasher, not shown, and which can also be employed for the removal of the closure or lid 10, when occasion requires.

From the above description, it will be obvious, that the lid 10 and the upper portion of the churn barrel being constructed as set forth, there will be no possibility of milk leaking past the closure during the churning operation.

The hand grip 3 carried by the lower end of the said barrel also affords convenient means for pouring out the contents of the churn and for otherwise manipulating the churn as may be desired.

The churn is here shown p'rovided near its upper end with a bail-shaped handle 5 to assist in handling it and for conveying it from place to place.

While the fluid tight connection between the container and the lid is herewith shown anddescribed as applied to a churn, obviously it may be used in any other container where a tight fit between the container and its closure is desired.

The preferred embodiment of the inven tion is disclosed in the drawings and set forth in the specification, but it will be unde'rstood that any modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

What I claim is:

A receptacle comprising a hollow cylindrical body portion provided at its top with an opening, a closure for mounting in said opening to close the latter, a lengthwise extending and laterally projecting boss formed integral with the outer face of said body portion in proximity to the bottom thereof and gradually increasing in thickness from its upper toward its lower end, a hand grip mounted in the lower end of said boss, and a bail connected to said body portion near the top thereof.

In testimony whereof, I afiix my signature hereto.

JOHN P. DONALDSON,
