CHURN.

SPECIFICATION forming part of Letters Patent No. 582,095, dated May 4, 1897. Application filed January 26, 1895. Serial No. 536,369. (No model.)

To all whom, t may concern/f Be it known that I, JAMES P. ROGERS, a citizen of the United States, residing at Kyle, in the county of Hays and State of Texas, have invented a new and useful Churn, of which the following is a specification.

My invention relates to churns, and particularly to dashers adapted forimpartinga combined rotary and linear movement to the contents of a churn, the object in View being to provide a simple, inexpensive, and efficient construction of dasher designed particularly for use in connectionv with an ordinary tub or receptacle, the same being an improvement upon the construction shown in my Patent No. 225,644, granted March 16, 1880.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.

In the drawings, Figure 1 is a perspective view of a churn constructed in accordance with my invention, partly broken awayto show the dasher. Fig. 2 is a vertical section of the same. Fig. 3 is a horizontal sect-ion taken on a plane below the upper cross-bar of the dasher. Fig. 4 is a detail plan view of the dasher.

Similarnumerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates a base having side beams 2, from which rise the standards 7, said side beams being connected by a transverse bar 3, and strips 4 being secured to the base contiguous to the inner surfaces of the side beams to prevent lateral vibration of the churn-tub 5. The upper extremities of the standards are connected bya cross-piece 8 and opposite plates 9 and 10, in the upper edges of which are formed bearings for the driving-shaft 21. Fixed to the drivingshaft is a master-gear20, having a crank 22.

The dasher is provided with a staff 13, having a reduced upper extremity 15, fitted in a bearing at the center of a bearing-bar 16, said bearing-bar being hinged, as at 27, to one of the standards and being adapted to rest at its free end upon a stop-block 18, secured tothe ,other standard.

A securing-pin 27 is employed to maintain said bearing-bar in its normal position. The tub or receptacle 5 is provided at its bottom with a transverse cleat 11, having a central socket 12, in which is mounted the reduced lower extremity 14 of the flasher-staff. Motion is communicated to the dasher-staff by means of the master-gear 20, which meshes with the pinion 19.

The dasher embodying my invention consists of upper and lower cross-bars 23, carried by the staff 13 and having their extremities connected by blades 24. c1oss-bai's,wl1ich are connected by each blade, are arranged at an obtuse angle to cach other, as indicated by the right-angularly-disposed dotted construction-lines of Fig. 4, the object of this arrangement being to increase the length of the blades without adding to the height of the dasher.

The blades are fitted at their upper and lower extremities in kerfs 25, formed in the extremities of said arms of the cross-bars, and these kerfs are arranged at an inclination oorresponding with the inclination of the contiguous portions of the blades and also diagonally with relation to the length of the arms, whereby the outer edges of the blades are disposed in advance of radii extending through the inner edges of the blades. The advantage derived froln this arrangement of the blades is that instead of forcing the fluid contents The arms of the of the churn outward centrifu gally during the rotation of the dasher, as when radially-disposed blades are employed, the effect is to impart a directly rotary motion to the contents. ln other words, the blades advance with their faces perpendicular to the direction of the motion imparted to the fluid. (See w Fig. Ll.) Under these circumstances the spiral disposition of the blades or their rearward inclination toward their lower ends causes the contents of the churn to be forced vertically downward and thereby produces a violent agitation of the same without dashing or scattering the liquid or causing the same to splash over the top of the tub or receptacle in case the cover is removed.

Various changes in the form, proportion, and the minor details of construction may be IOO planes at an obtuse angle to each other, Whereby each blade traverses an are greater than ninety degrees, the disposition of said kerfs providing for the disposition of the outer edges of the blades in advance of radii extending through the inner edges thereof to insure the blades advanein g with their faces perpendicular to the direction of the motion imparted to the fluid, substantially as set forth.

In testimony that I claim the foregoing as my own I have heretoafiixed my signature in the presence of two Witnesses.
