ALEXANDER HART, OF STOOKBRIDGE, WISCONSIN.

IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 39,650, dated August 25, 1863.

.To all whom it may concern:

Beit known that I, ALEXANDER H. HART, of Stockbridge, Calumet county, and State of Wisconsin, have invented a new andImproved Mode of Operating Dashers in Ohurns; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in providing an upright conical-formed box as a churn with two paddles connected by a suitable apparatus to a lever, so that each upward or downward motion of the lever will give the paddles or dashers an oppos n g vibratory motion, whereby they will be on a right line with and pass each other ata point when each has traveled onehalt' its allotted distance, thereby as the lever is worxed up and down producing a violent agitation of the cream.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct a box, A, Fig. 1, with a bottom, 13, that is nearly or quite equilateral with two of its opposite sides at right angles with the bottom and extending above the top of the box in a conical form, and the remaining two sides inclininginward about twelve degrees. I construct a bar, 0, provided with pins (1 01, set in an opening in the cover, to which are hung the paddles cc, and with mortisesff to receive the arms of the slide g. The bar is placed in the groove running in an opposite diagonal direction on the respective sides. The paddles e e are each provided with a pin, j, with a head properly formed to work in the grooves i t, which is attached thereto at such a point that when the lever h gives the slide g its up-anddown motion, they (the pin j, there being one attached to each arm of the respective padtiles) will work in the diagonally-placed grooves i i, thereby giving the paddles their vibratory motion, each in areciprocally opposite direction and causing the agitation of the cream, and the consequent results therefrom of producing butter with expedition and case.

What I claim as my invention, and desire to secure by Letters Patent, is-- The slide g, provided with the oblique grooves z i, and operated by the lever It, in combination with the dashers E E, the whole constructed, arranged, and operatingin the manner and for the purposes herein set forth.

A. H. HART.
