I MPROVED CHURN A ND BUTTER-WORKER.

Specification forming part of Letters Patent No. 34,144, dated January 14, 1862.

To all whom it may concern.-

Be it known that we, ADAM HAWVER and W. H. HANYEN, both of Galva, in the county of Henry and State of Illinois, have invented a new and Improved Churn and Butter- VVorker; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,making a part of this specification, in which Figure 1 is a plan of our improved churn with the cover removed to show the internal arrangement. Fig. 2 is a vertical longitudinal section taken in the line so a: of Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates .to that class of churns in which a reciprocating dasher is employed to effect the liberation of the butter, the object being to obtain a simple and efficient device for churning which will answer equally well to work the butter after it has been churned; and it consists in an arrangement of a dasher to work over an inclined bottom and in connection with a concave at its lower end, whereby the cream is kept constantly agitated and subjected to a great amount of friction, thus effecting the desired result in an easy and expeditious manner.

To enable others skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents a box or cream and milk receptacle, which has an inclined bottom B and concave C, and is supported on four legs a 1), two on each side. The sides of the box near the top of the inclined bottom have a vertical groove cut in them, in which a partition formed in two parts 0 dis inserted to prevent the cream from being thrown out over the upper end of the incline.

The dasher D corresponds in length with the width of the box, and is attached near its bottom edge in the middle and at an angle of about sixty degrees to one end of the staff E, which is fitted to play through an opening in the partition, one-half of which is made in each of the parts 0 d, and has handles j, attached at its upper end. The back, side, and

top edge of the dasher is chamfered its entire length and has a series of perforations t' passing transversely through it, through which a portion'of the cream in the box is compelled to pass at every stroke of the dasher, thus increasing the mechanical action of the fluid and facilitating its formation into butter. The bottom edge of the dasher is beveled to fit into the angle formed by the union of the concave O with the inclined bottom B, thus insuring contact of the dasher with every particle of cream and churning a large or small quantity with equal efficiency. At the upper end of the inclined bottom is a circular flange e, which has a section 9 fitted in the middle of it with a dovetail, so that it can be removed to pour off the buttermilk after a churning.

The cover F is fitted in half rabbets in the sides of the box flush with the top, and is fastened by buttons f-one on each side. The back end of the cover is beveled to fit into an undercut groove in the concave to make a tight joint. A space is left between the the lower half of the partition d and inclined bottom to allow the atmosphere to mix with the cream, and also to furnish a passage for the cream drawn through the opening in the partition by the staff to return into the box.

The operation of our improved churn is as follows: The cream being placed in the box and the cover fastened in place by the buttons, a reciprocating motion is imparted to the dasher through the medium of the handles. As the dasher is drawn toward the upper end of' the incline, it gradually rises therefrom to allow the cream and milk to pass under it. After the operation of churning is performed the cover is taken off to admit of the section of the flange to be removed, when the cover is is replaced and the box tilted to pour off the buttermilk, it passing through the opening under the partition and flange. After the buttermilk has been poured off the churn is set in an upright position, the cover removed, and the butter worked against the concave with the dasher, the buttermilk being poured off over the upper end of the incline, as before mentioned.

The within-described churn is simple in its construction, portable, easily operated, and readily cleansed.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

The dasher D, staff E, concave C, inclined bottom B, partition 0 d, circular flange e, and

section g, when combined, arranged, and operating in the manner and for the purpose set forth.
