IMPROVEMENT IN CHURNS.

Specication forming part of Letters Patent No. 118,320, dated August 22, 1871.

To all whom it may concern:

Be it known that I, ELI WmLcoX, of Haniburg, in the county of Fremont and State of Iowa, have invented a new and useful Improvement in Churning Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this speciiication.

Figure l is a detail vertical section of my improved churning apparatus. Fig. 2 is a detail sectional view of the same, the inner case being removed. Fig. 3 is a detail top view of the churnbody, the cover and operating mechanism being removed. f l

Similar letters of reference indicate corresponding parts. l

My invention has for its object to furnish an improved churning apparatus which sh all be simple in construction, easily operated, conveniently cleaned, and effective in operati on, doing its work quickly and well 3 and it consists in the construction and combination of various parts of the apparatus, as hereinafter more fully described.

A represents the outer case or body of the churn, which may be supported upon legsBif desired. C is an inner tin case, made of. a somewhat-less diameter than the outer case A, and provided with short feet c1 upon its bottoni to support the case C at a little distance above the l bottom of the outer case A, thus forming a space all around between the cases A C to receive hot or cold water, as the case may be, for tempering the milk or cream in the inner case C. In the center of the bottom of the case C is formed a step, c2, to receive the pivot of the dasher-shaft. The step e2 enters a recess or step, a', in the center of the bottom of the outer case A, and thus prevents the lower end of the inner case C from moving about upon the bottom of the case A. D is the cover, which is rabbeted around its lower edge, so that its middle part may project into the mouth of the inner case C, and thus serve as a cover to the said inner case at the same time that its rabbeted edge rests upon the upper edge of the outer case A, and thus covers the said outer case securely. To the sides of the upper end of the inner case C are pivoted rin gs E, which drop into slots in the upper edge of the outer case A to prevent the upper end of the inner case 'C from moving about when the churning is being done. The rings E also serve as handles for convenience in handling the caseO. F is the dasher-shaft, to the lower end of which is attached or upon it is formed a pivot, which works in the step or recess c2 in the bottom of the case C or in the step or recess a iu the bottom ofthe case A when the inner case is not used. To the shaft F are attached cross-bars or arms G, to the ends of which are attached vertical bars or beaters H, which, as the dasher-shaftF is revolved, throws the milk against the sides of the churn. To the sides of the case C are attached vertical ribs I, against which the milk strikes as it is thrown outward by the dasher, and which break up the currents and throw the milk into violent agitation, bringing the butter in a very short time. J are vertical ribs attached to the sides ofthe outer oase A, and which operate in the same manner as the ribs I when the inner case Gis not used. The upper end ofthe dasher-shaft F passes up through a hole in the center of the cover D, and upon its upper end is formed or to it is attached a pivot or journal, which enters and works in a socket in the cross-bar K, which is rigidly attached-to the upper ends of the arms L, the lower ends of which are inserted in keepers or sockets M attached to the sides of the case A, where the said arms may be detachahly secured in place by pins or other convenient means. To the upper and lower sides of the bar K are attached or upon them are formed flanges c,which enter grooves in the bars N placed above and below the bar K, and which are connected and held in place upon the bar K by cross-bars attached to them, as'shown in dotted lines in Fig. 1. To the lower sliding bar N is attached a toothed rack, 0,' the teeth of which mesh into the teeth of the small gear-wheel I), attached to the upper end of the dasher-shaft F or to the journal of said shaft. rlhe sliding bars N may be operated to operate the dasher by means of p handles Q attached to the upper bar F; or, if desired, the said sliding bars N may be operated by a lever, R, connected with the lower bar N by a connecting bar, S, one end of which is pivoted to the said bar N and the other end of which is pivoted to the said lever R. The lower end of the lever R is pivoted to the lower part of the body A, as shown in Fig. l.

The apparatus may be operated by hand or power, as may be desired or convenient.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- Vl. An improved churning apparatus, consisting of the arms L, bar K, sliding bars N, toothed ing bars N, toothed rack O, gear-Wheel P, dashraek O, gear-wheel P, dasher-shaft F, dasher G er-shaft F, dasher G H, inner ribbed ease C I, H, and ribbed oase or body A J, Whether the inand outer ribbed ease A J with each other, ner ease C I be used or not, said parts being eonsubstantially as herein shown and described, and

strueted, arranged, and operating substantially for the purpose set forth. as herein shown and described, and for the pur Witnesses: ELI WILLCOX.
