CHURN.

SPECIFICATION forming part of Iletters Patent No. 436,213, dated September 9, 1890 Application filed April 23, 1890. Serial No. 349,084. (No model.)

To all whom it may concern:

Be it known that I, SIMON CLARK, a citizen of the United States, residing at WVinston, in the county of Daviess and State of Missouri, have invented new and useful Improvements in Ohurns, of which the following is a specification.

This invention relates to that type of churns having a swinging dasher comprising horizontal beaters, which are substantially triangular in cross-section.

The object of my invention is to improve the prior dasher by providing a novel construction, whereby the flow of the cream through the dasher at the ends of the heaters is facilitated.

The invention consists in a churn-dasher comprising horizontal beaters of'substantially triangular form, having openings between them for the passage of the cream, and side bars carrying thebeaters and having beveling, diverging cut edges arranged at and rising above the ends of the heaters to facilitate the flow 0f the cream through the dasher at such beveled parts.

In. the accompanying drawings, Figure 1 is a central vertical section of a churn embodying my invention, the lid being removed. Fig. 2 is a transverse vertical section, the dasher being in elevation. Fig. 3 is a view of the lid.

In the said drawings, the reference-numeral 1 denotes the body of the churn, which is of any desired capacity, from four to eight gallons being that usually employed. Viewed in side elevation the churn-body has substantially the form of a segment of circle, the se ment being truncated at its upper and smaller end. This body is mounted upon legs 2. Its bottom 3 is preferably composed of a sheet of galvanized iron, zinc, or other suitable metal; but it may be also provided with an interior lining of galvanized iron to secure perfect cleanliness. A vertical flange 4 surrounds and rises above the rectangular open mouth.

The reference-numeral 6 designates the churn-dasher, which is composed of a rectangular plate of wood of such width as to substantially span the interior space of the churn. The dasher is provided with a series of transverse beaters 7, of substantially triangular form in cross-section, the base of said rectangle being arranged at right angles with the parallel side pieces 8 of the dasher, while the apex lies in the central line of such side pieces. Between the apex of each beater and the base of the one next above a sufficient space is allowed to admit of the passage of the cream. At the ends of the heaters are formed beveling cuts 9, extending from the base of one beater to that of the next above and entering the side strips 8 at an outwardlydiverging angle, whereby at each stroke in either direction certain portions of the cream are, by means of these beveling faces, forced laterally inward or toward the center of the dasher, and caused to pass through the same between the heaters.

United with the dasher is the lever by which it is operated, consisting of two parallel bars 9, of metal or othermaterial, which pass through longitudinal openings in the side pieces 8, and protrude at the lower ends of said pieces, their ends receiving washers or nuts 10. After emerging from the upper ends of the side pieces 8, the bars 9 slightly diverge, and are then bent sharply outward, forming journals 12, which rest in seats 13, formed centrally and transversely in the edges of the side pieces.

In order to prevent rapid wear, journalblocks 14 will usually be inserted in recesses formed in the opposite side walls of the churn, said blocks being formed of any suitable hard wood.

The journals 12 are of such length as to pass into two triangular recesses 15, formed in the flange l, which surrounds the open mouth of the churn, and at their outer ends the bars are bent vertically upward and extended to a suitable point above the top of the churn, where their ends are united to a connecting cross-bar 16.

The journals 12 are retained in the seats 13 5 by means of latches 17, pivoted upon the flat upper edges of the walls of the churn and adapted to swing over and. hold the journals in place.

The mouth of the churn is closed by a re- I00 movable lid formed in two parts 18 and 19, the former portion being of such size that it will enter and substantially fit the open mouth of the churn, angular recesses 20 being formed in the edges of the part 18 to receive the inner ends of the journals 12 and permit the swing of the lever.

The part 19 is united to the part 18 in such manner as to form a projecting edge or flange 21, which is received within the flange 4: and rests upon the open top of the churn. Recesses 22 are formed in the lower faces of the projecting edge 21 to accommodate the latches 17.

It will readily be seen that by this construction of cover or lid the escape of the cream will be rendered practically impossible, While the parts are very simple in form, readily removed and replaced, and quickly and easily cleaned.

What I claim is In a churn, a dasher consisting of a series of horizontal heaters of substantially triangular form, having openings between said heaters for the passage of the cream, the side bars by which said heaters are carried having beveled diverging cut edges 9, arranged at and SIMON CLARK.
