EZEKIEL GORE, OF BENNINGTON, VERMONT.

CHURN'.

Specification of Letters Patent No. 12,127, dated January 2, 1855.

To all whom it may concern:

Be'it known that I, EZEKIEL GORE, of Bennington, county of Bennington, State of Vermont, have invented a new and useful Improvement in Churns; and I do hereby declare that the following is a full, clear, and exact description of the same.

The nature of my improvement consists in perforating the sides of the churn and introducing therein a series of adjustable pins, flattened at their inner extremities, which may be turned by the hand from the exterior of the churn, so as to present a greater or less surface of resistance to the cream, when put in motion by the dasher.

To enable others skilled in the art to make and use my improvement, I will proceed to describe its construction and operation, reference being had to the annexed drawings, making a part of this specification, in which,

Figure 1, is a vertical sectional elevation of my improvement; Fig. 2, a horizontal sectional plan view.

Similar letters of reference indicate cor responding parts in the two figures.

A is the case of the churn, B the dasher spindle, C the floats, D the adjustable pins, E cover, E bearing of spindle, F ribs.

In the process of churning it is desirable to have some means of producing a ceaseless agitation among the oily globules of butter contained therein, and also of regulating at pleasure the resisting surface presented to the cream.

Then the cream to be churned is thin, the resisting surface within the churn should be greater than when it is of a thick consistency, for greater agitation is requisite in the former than in the latter case. In agglomerating or collecting the butter after it has come little agitation is desired. By the arrangement of my improved churns, these very important results are efi'ectually obtained.

The pins D, flattened on their inner extremities, pass from the outside of the case (A) of the churn, in toward the center of the churn, as shown in the drawing. They terminate, upon the outside of the churn, in convenient thumb balls, by which they may at all times be adjusted.

It is manifest that the resisting surface exposed to the moving mass of cream Within the churn, will be greater or less according as the flattened ends of the pins D are turned edge wise'or side wise. When the cream is thick the pins are turned so'that only their edges will oppose the cream. \Vhen the latter is thin, then their sides are presented. It is but the work of a moment to adjust the resisting surface to any desired degree. The sides of the churn, within, are also furnished with short ribs, placed at small distances apart. These serve to give additional stability to the be'arin s of the pins, while their sharp corners 0 er resistance to the cream and promote agitation. The floats C are so arranged as to move in close proximity to the tops and bottoms of theribs F, and thus prevent any particles of butter from collecting at the sides of the ribs, above the sweep of the floats. No particularnovelty is claimed for the floats in themselves. They are attached to the spindle C in the usual manner.

By means of the invention herein described I am enabled to make achurn at a very trifling cost, which eifects the separation of the butter from cream or milk, in a remarkably short period of time, and in the most thorough manner. some individuals, butter, when very quickly, produced, is not of so good a quality, as when longer time is spent in the churning. By means of my adjustable pins, the time of churning may be regulated to suit the flat, and so arranging them that they may be turned to the right or left, as desired,

In the opinion of and thus made to present a large or small i resisting surface to the agitated cream and facilitate or retard the production ofbutter substantially as setforth.
