CHURN.

SPECFICATION forming part of Letters Patent No. 414,632, dated November 5, 1889.

Application iiled August 5, 1889. Serial No. 319,740. (No model.)

To all whom it may concern:

Beit known that I, HENRY W. ORAIL', a citizen of the United States, residing at Mattoon, in the county of Coles and State of Illinois, have invented certain new and useful Improvements in Ohurns, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure l represents aside elevation, partly in section, of my improved churn; Fig. 2, a vertical sectional view of the same, and Fig. 3 a perspective view of the stationary dasher.

The invention has relation to certain new and useful improvements upon that class of churns wherein the dasher is held stationary within a rotatable churn-vessel; and it has for its objects to improve the general construction of this class of apparatus and render it more efficient and simple, as will be more fully hereinafter set forth.

A In the drawings annexed, a. designates a cast metallic frame provided with a disk b at its lower end. To the disk b is secured,by a central screw c, a similar disk d, which is provided with a suitable number of depending radial wings e, to which are bolted the supportingdegs f, the upper ends of the legs being slotted for the reception of the said wings.

By removing the central screw c the lower disk and legs may be removed for convenience in transportation or for any other purpose.

A vertical shaft g is journaled in the frame, and is given motion by means of apair of gear-wheels and a horizontal shaft h, also journaled upon the frame. The shaft h is rotated by means of an adjustable crank or handle 7a', or by any other suitable means. The upper end of the shaft g is provided with a horizontal disk g for the support of the churn-vessel 2'-, this vessel being provided with a central pin j and a series of radial projections l.; upon its bottom, these projections and central pin fitting in similar sockets in the said disk g. This construction causes the vessel to rotate with the disk, and permits of the use of4 larger or smaller vessels.

Within the vessel, transversely of its bottom, is removably secured a bar Z, which assists in the churning process.` This bar is provided with rubber cushions in its ends, which bear against the interior of the vessel and serve to hold vthe bar in any desired position without bulging or breaking the vessel.

Mounted and suitably secured on the main frame, to one side of the churn-vessel, is a vertical stationary rod m, which supports and forms a pivotal point for a tubular arm n, the 6o rod 'm extending up in the vertical portion of the said arm n, and being held adjustably therein by means of a setserew n. The horizontal portion of the bowed arm 'n extends over the top of the churn-vessel, and is 6 5 provided with a slotted cuff p at its end, this cud being directly over the central opening in the churn-cover. This cuff is provided with coincident slots p' upon its opposite sides for the reception of pins Aq upon the vertical dasher s, whereby the dasher-shaft is removably secured in said cuff without being permitted to revolve. The dasher-shaft and cuff4 are preferably formed rectangular in cross-section. The dasher-shaft extends down through the central opening in the churncover, and is provided at its lower end with a horizontal slotted arm t, to which are adjustably secured two or more vertically-corru gated blades w, these blades being secured to the arm t by nuts and bolts vw. By these nuts and bolts the plates may be adjusted along the arm, and their Obliquity with respect to each other may also be varied as the exigencies of the case may demand.

By providing for the vertical adjustment of the dasher-supporting arm different-sized churns may be readily accommodated, and by providing for swinging it around to either side the churn-vessel may be readily removed from 9c its support.

The operation of the churn will be evident from the foregoing.

Having thus fully described my invention, what I claim isl. The combination, with the main frame provided with a disk b at its lower end, of a similar disk d, provided with radial depending wings, a central screw c, for removably securing the disk cl to the disk Z), and legs f, bolted to the said radial wings e, substantially as described.

IOO

5 sponding' projections, substantially as described.

3. The combination of a frame, a rotary churn-vessel mounted upon this frame, means for rotating this Vessel, a bent arm n, mounted 1o upon the frame, this arm being rotatively and vertically adjustable, whereby its horizontal portion may be swung,` around centrally of the said churn-vessel, and a depending,` churndasher removably secured to the bentpor- 15 tion of said arm n, this dasher extendinginto the churn-vessel, as and for the purposes set forth.

4. The combination, with a churn-vessel, of

a transverse bar Z, provided with elastic buffers in its ends, substantially as ,and for the purpose described.

5. A dasher-rod s, provided at its lower end withY a horizontal arm t, having` a longitudinal slot, in -combination with a pair of vertically corrugated blades w, provided. with bolts and nuts whereby they are adjustably secured in the slot in arm t, these blades bein g thereby adapted to be adj usted rotatively and to or from each other, as and for the purposes set forth.

In testimony whereof I afxmy sign ature in presence of two witnesses.
