IRA A. SABIN, OF KALVESTA, KANSAS.

CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 406,308, dated July 2, 18 89.

I Application filed January 19, 1889. Serial No. 296,833. (No model.)

T 0 all whom, it may concern:

Be it known that I, IRA A. SABIN, a citizen of the United States, and a resident of Kalvesta, in the county of Garfield and State of Kansas, have invented certain new and useful Improvements in Ohurn-Dashers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view, partly in section, of a churn-body provided with my improved churn-dasher. Fig. 2 is a longitudinal section through the dasher-staff. Fig. 8 is a horizontal section of the lower end of the dasher, and Fig. at is a cross-section through one of the dasher-blades on an enlarged scale.

Like letters of reference denote corresponding parts in all the figures.

My invention has relation to vertical reciprocating churn-dashers; and it has for its object to provide a device of this character, in which the operation of churning is accomplished in a simple, easy, and expeditious manner; and with these ends in view it consists in the improved construction and combination of parts of the same, as will behereinafter more fully set forth and described.

In the accompanying drawings, the letter A designates the churn-body, and B the removable cover thereof, provided with a central perforation C. Passing through this central perforation is the dasher-staif D, having its lower end formed or provided with an en largement E, square or rectangular in shape, the angles or corners of said enlargement being provided with recesses F. The dasherst-aif is also provided above and below this lower enlargement with a series of dasherblades G and H, respectively, said blades being wedge-shaped upon their upper surfaces with a gradual taper from each end inwardly, so as to form a contracted or narrower inner portion, in this manner tending to draw the cream toward the center, and thereby lessening the weight exerted upon the dasherblades, wedge-shaped and tapering toward their inner ends, forming approximately Maltese crosses, while their outer ends are conical, as shown clearly in Fig. 4c.

The upper dasher-blades G are provided on their under sides with longitudinal slots or recesses I, adapted to receive intermediate dasher-blades J, the inner ends of said blades passing into the recesses F in the angles of the enlargement E, two of said blades being provided with shoulders j, adapted to bear against the under section of the upper blades G.

As will be seen, both the upper and lower dasher-blades are composed of two pieces crossing each other at right angles and formed or constructed in the manner hereinbefore pointed out. Each one of these pieces or sections is provided at its central decreased portion with registering-recesses, the dasher-statf passing through central registering-perforation in said recesses in both the upper and lower series of blades.

In operation, on the downward motion the cream escaping from beneath the lower dashers is brought in direct contact with the intermediate and upper blades, thereby insuring a thorough agitation of the cream. On the return or up stroke there is but very little weight to be overcome or encountered,owing to the wedge shape or incline of the upper and lower dasher-blades. The inclines upon the upper blades will have a tendency to deflect the cream and throw it against the opposite intermediate blade, from whence it is again deflected to the incline of the lower blade.

It will thus beseen that not only is the cream subjected to the action of all the series of blades on the downstroke, but also on the upward stroke, thus necessarily subjecting the cream to a most thorough agitation.

The device is furthermore exceedingly strong and durable and little liable to get out of order, the parts all being firmly and SL, curely connected.

From the foregoing description, taken in connection with the accompanying drawings, the operation, construction, and advantages of my improved churn-dasher will be readily understood without requiring further explanation.

Having thus described my invention, what I and the lower blades provided with wedgeshaped upper surfaces with a gradual taper from each end inwardly and extending radially between the spaces and alternating with the upper set of blades, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereunto aflixed my signature in presence of two witnesses.
