EMMA G. THOMAS, OF OOMSTOOK, OHIO.-

CHURN-DASHER.

SPECIFICATION forming part of Letters'ratent No. 661,159, dated November 6,1900.

Application tiled March 14, 1900. Serial No. 8,686. KNO model- To all whom it may concern.-

Beit known that I, EMMA G. THOMAS, a citizen ofthe United States,residing at Comstock,

in the county of Sciota and State of Ohio, have invented certain new and useful Improve ments in Ohurn-Dashers; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to improvements in churn-dashers'; and the object is to provide a dasher of simple construction and easily operated with a minimum expenditure of labor.

Vith these ends in view the invention consists in the novel construction and combination of parts, as will -be hereinafter more in detail described, and particularly pointed out in the claim.

In the accompanying drawings, to which reference is had and which fully illustrate my invention,-Figure l is a perspectivev View. Fig. 2 is a vertical section of the same, and Fig. 3 is a plan View of the bottom thereof.

Referring to the drawings, A designates the dasher, composed of two sections-an upper and a lower section-the lower one Vof which consists of two horizontal wings B B, recessed upon its under side, the recesses being formed by iianges a and the wings being disposed relatively to each other in such a manner as to describe a cruciform figure and secured upon the lower end of the dasher-shaft in a manner which will be hereinafter explained. Centrally secured to this dasher-section is a short tube C, by means o f which this section of the dasher is secured to the dasher-shaft. Near the free ends of the wings or arms B B of the dasher-section is disposed a suitable number of perforations of different diameters, as clearly shown in Fig. 1 of the drawings.

D designates the upper section, which is in the form of the frustum of a cone and provided cenirally witha short tube E, similar to that of the lower section of the dasher and in alinement therewith, through which the dasher-rod is passed, and interposed between the dasher-rod and the short tube E is a gasket or packing e. A bolt-fastening f, which is screw-threaded upon one end, has a nut enl gaging the same, the boltbeing passed transtogether.

versely through the short tube E, gasket e, and dasher-rod, securely fastening these parts This section of the dasher is also provided with semi-elliptical tubes F upon its surface in a radial manner from its center, having'their outer and larger ends open for the free ingress of the cream, and beneath these elliptical tubes at their inner or smaller ends and formed through the dasher are a number of U-shaped openings, one forl each tube, these U -shaped openings registering with the larger openings in the lower section, and formed within the dasher, between each of these semi-elliptical tubes., are a suitable number of pcrforations smaller in diameter than the U-shaped openings. l

By my peculiar construction of dasher and the arrangement of the larger perforations or openings and the smaller ones of the same upon both sections of the dasher it will be perceived that I am enabled to produce such circulation and friction of the cream as will quickly and thoroughly produce butter, and among other advantages it is economical in construction, durable, and not likely to get out of order.

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

The combination with the lower cruciform section having the perforations of different diameters near the ends of the wings of the same, and a central tube of the upper section forming the frustum of a cone, and having the semi-elliptical tubes, and U -shaped openings in the dasher directly beneath the inner or smaller end of the elliptical tubes, the el- V-liptical tubes disposed radially upon the sec- EMMA G. THOMAS'.
