EDWARD F. SNEAD AND HENRY O. STINNETT, OF BUCHANAN, VIRGINIA.

IMPROVEMENT IN ROTARY CHURNS.

Specification forming part of Letters Patent No. 186,174, dated January 9, 1877; application filed September 9, 1876.

To all whom it may concern:

Be it known that we, EDWARD F-SNEAD and HENRY C. STINNETT, of Buchanan, in the county of Botetourt and State of Virginia, have invented a new and valuable Improve- .ment in Ghurns; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference beinghad to the annexed drawings, making a part of this specification, and to the letters and figures of ref- .erence marked thereon.

Figure 1 of the drawings is a representation of a central vertical section of our churn, and Fig. 2 is a side elevation thereof. Fig. 3 is a horizontal vertical sectional view, and Fig. 4 is a plan view of our churn without gearing dasher-supporting frame.

This invention relates to improvements in churns bar ing rotary dashers; and it consists in the combination of the devices hereinafter described and claimed.

In the annexed drawings, A designates an upright cylindrical churn -box, which is provided with vertical grooves or channels A A, adapted to receive the stilesor standards B B of a daslier-supporting frame. Said stand- I ardsrare connected at the bottom by crosspiece B and near the top of said churn-box by upper cross-piece B. Said standards also extend vertically above the top of said churnbox, and, with said cross-pieces, complete the said supporting-frame. G designates a vertical rotating dasher-shaft,journaled in the middle parts of cross-pieces B and B, and provided with radial dasher'arms c c. The upper journal of said rotating dasher-shaft is pro longed, so as to form a vertical and rotating rod, (3, which carries a bevel-geared pinion or v small wheel, D. Said pinion meshes with a 7 vertical bevel-geared wheel, E, which is journaled, by horizontal rotating shaft F, in boxes G G, that are secured to standards B B near the upper ends thereof. Said horizontal rotating shaft is connected to and rotated by crank-arm H. To the inside of standards B B, within the said churn-box A, are secured two opposite series of inwardly-extending rods or bars, b b. Said bars alternate with the said dasher arms or bars 0 0, so that when the said crank is operated the said revolving dasherarms b I) turn through the spaces between the said fixed bars a c. This stirs and churns the milk or cream very effectually. I I designate the two segmental sections of a cover to said churn-box. Said sections are recessed rectangularly at 'i t', to receive standards B B, and perforated centrally at i, to allow the passage of vertical rod 0, already described. They are also provided with handles I I upon their tops to facilitate their removal. For the same purpose standards B B may be detachabl y secured in grooves or channels A A.

Rod 0, bevel-geared pinion D, bevel-geared wheel E, and shaft F are all constructed of metal, and preferably of iron. The remaining devices are preferably constructed of wood.

What we claim as new, and desire to secure by Letters Patent, is-

l. A churn-box having opposite interior longitudinal grooves adapted to receive a dasher-supporting frame, which extends entirely across the interior of the churn-body, substantially as and for the purpose set forth.

2. The churn-box A, having opposite interior vertical grooves A A, in combination with the removable frame B B B, provided with arms b b, and shaft F, having bevel-gear E, and the dasher-shaft 0, provided with arms 0 and bevel-gear D, substantially as and for the purpose set forth.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
