CHARLES A. JAPHET, OF VINOIIESTER, KANSAS.

CHURN.

SPECIFICATION forming part of Letters Patent No. 426,186, dated April 22, 1890.

Application filed September 16, 1889. Serial No. 324,019. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES A. J APHET, a citizen of the United States, residing at Vim chester, in the county of Jefferson and State of Kansas, have invented a new and useful Churn, of which the following is a specification.

This invention has relation to that class of churns known as swinging dasher, and among the objects in view are to provide a churn of exceedingly simple construction and adapted to thoroughly and quickly bring the butter, and also serve to clean the same and press the buttermilk therefrom. By means of the construction of my churn-that is, the body portion and the dasher and their relative arrangement with each other-I am enabled to agitate the cream sufficiently to bringthe butter quickly and yet preserve the grain thereof, and at the same time gather the butter efficiently and with rapidity.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claim.

Referring to the drawings, Figure l is a perspective of a churn constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section. Fig. 3 is a transverse vertical section. Fig. at is a detail in perspec tive of the dasher.

Like numerals of reference indicate like parts in all the figures of the drawings.

The churn-body comprises two side walls and two end walls. The side walls 1 are in the form of an isosceles triangle, having opposite converging edges, and at their upper ends said walls terminate in one side of asquare neck. At the intersection of the imaginary lines, which are a continuation of the edges of the side walls, (see dotted lines, Fig. 2,) I provide U-shaped bearings 3 in the upper edges of said wall. The end walls at are secured to the opposite edges of the side walls, and consequently are upon the same inclination as are the edges of said side walls, and, like the side walls, are provided at their upper ends with a vertical portion 5, which co1nbines with the upper ends of the side walls to complete the rectangular neck 6, which in this instance is inclosedby a similarly sh aped collar 7, the inner upper edges of which are provided with recesses 8, forminga continuation of the bearings in the upper edges of the side walls. The bottom 9 of the churn is curved, the radius of which is the bearingin the upper edges of the side walls, or, in other words, at the intersection of the dotted lines forming a continuation of the opposite inclined edges. A cover 10 is mounted within the collar and rests upon the upper edges of the side and end walls forming the neck.

The dasher-shaft consistsof two opposite rods 11, connected at their upper ends by a cross-bar or handle 12, and are at a suitable point inwardly bent to form bearing-shoulders 13, to rest in the hearings in the neck and collar. The distance between the opposite rods equals that between the walls of the bearing, so that as the cover is adapted to fold within the collar it will also be inside of or between the opposite rods. After forming the shoulders 13 the rods are continued in parallelism and passed through longitudinal openings 1%, formed in the opposite side bars of thedasher-frame, and through to the opposite ends of said bars, where they are secured by nuts 15.

The dasher-frame is constructed of one piece of hard wood and comprises opposite side bars 16 and upper and lower connectingbars 17. The bars 16 are connected at intervals by transverse blades 18. These blades 18 are preferably formed integral with the side bars and in cross-section are in the shape of an equilateral triangle, comprising opposite inclined planes converging toward each other, lower acute angles, and an intermediate horizontal plane. \Vhen the dasher is mounted in position, itwill be noticed that the same may be tilted so that it will be brought squarely against either of the end walls, or, in other words, exactly parallel therewith.

In moving the dasher back and forth it will be observed that as the dasher leaves one wall it forms a partial vacuum for the moment, and that the cream is crowded toward the other wall and is then drawn through the space between the series of slats forming the dasherframe. In the rush to pass through the cream comes in contact with one of the lower acute angles and is directed. up the inclined plane into contact with the horizontal plane of the blade above, and thence down the opposite inclined plane. In this manner a most thorough agitation and separation of the globules of cream is accomplished and air introduced to the very bottom of the churn. As the cream is converted into butter it rises to the top and is caught by the blades of the dasher and pressed against the inclined end walls, and is crowded thereagainst until thoroughly eradicated of the liquid, and afterward strained, so to speak, or pushed through between the blades to the opposite side of the dasher, Where the operation is again repeated. After the butter has been made and the buttermilk withdrawn a thorough washing of the butter may be accomplished by the introduction into the churn of clear water. Now by agitating the dasher the butter is pressed against one side of the inclined end, and when the dasher is moved to the opposite side the current of the water is such as to roll the but: ter from its sheet-like form into roll form and carry the same over to the opposite side. In this manner the most thorough washing is given the butter and the same is then ready for salting.

The churn may be thoroughly cleansed now by an introduction of warm water and an agitation of the dasher. In this agitation of the dasher for cleaning purposes the same advantageous movements of the water take place as previously described, the currents being directed in such a manner as to most thoroughly eradicate all traces of the milk or butter.

The construction of the churn is such that the interior is wholly devoid of any crevices, small orifices, or other forms adapted to afford places of concealment for butter or milk, the walls all being perfectly plain, and therefore subject to a thorough and efficient cleaning, as caused by the agitation of the Water therein. Furthermore, it will be noticed that the bearing-points of the dasher are located considerably above the cream-line, and hence no black foreign matter generated by the bearings will come in contact with the body of cream and streak the butter, by which the same would be depreciated in value.

Having thus described my invention, what I claim is- In a churn the herein-described dasher, consisting of opposite rods connected at their upper ends and bent to form bearing-shoulders, and having a flat dasher-frame consisting of opposite side bars longitudinally bored to receive the rods, upper and lower connectin g-bars, and a series of intermediate connecting-blades triangular in cross-section and arranged with their bases at a right angle to the faces of the side bars, so that the apex of one blade will be just below the longitudinal center of the base of the blade above, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
