CHURN.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed May 18, 1906. Serial No. 317,445.

To all whom, it may concern/.-

Be it known that l, GEORGE VILLIAM HAMILTON, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a new and useful Ohurn, of which the following is a specification.

This invention has relation to churns, and it consists in the novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide a simple and eificient construction and arrangement of parts whereby the separation of the butter is facilitated.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof are hereinafter brought out.

ln the accompanyingdrawings, Figure 1 is a vertical sectional view of the churn proper, showing the frame and gearing in elevation. Fig. 2 is a perspective view of the dasher, and Fig. 3 is a horizontal sectional view cut on the line 3 3 of Fig. 1.

The frame consists of the base 1, from which is erected the upright 2. The churnbody 3 is adapted to rest upon the base 1. The shaft 4 is journaled in the upright 2, and to one end of said shaft is fixed the iiy-wheel 5, provided with a handle 6, and to the other end of said shaft is fixed the gear-wheel 7. The upper portion of the upright 2 is carried forward, as at 8, and is provided with the additional metal 9 in the form of a verticallyextending web. The depending section 10 extends down over the top section 8. The counter-shaft 11 is journaled in the depending section 10 and in the upright 2. Said counter-shaft is provided with a gear-wheel 12, which meshes with the gear-wheel 7, and upon its end is provided with the bevel gearwheel 13. The pin 14 is vertically located in a perforation in the top section S and is adapted to be held in position therein by means of a set-screw 15. The vertical shaft 16 is adapted to enter the churn-body 3. Said shaft is provided at its upper end with a recess 17, adapted to be entered by the lower end of the pin 14. The bevel gear-wheel 13 is provided on its upper side with a collar 19. The bevel gear-wheel 18. is located upon the upper end of the vertical shaft 16 and is held in place thereon by the set-screw 20, which passes through the said collar 19. The bevel gear-wheel 18 meshes with the bevel gearwheel 13. The clips 21 are pivotally supported at the lower end of the depending section 10 of the frame. The shaft 16 passes through recesses formed in said clips, the said clips fitting together in such manner as to form a bearing. The pin 22 passes through lugs 23 and also through the Shanks 24 of the said clips. The outer ends of the clips are held together by a screw 25. The dasher is attached to the lower end of the shaft 16. Said dasher consists of a sleeve` 26, adapted to receive the said shaft, the set-screw 27 passing through the said sleeve and adapted to engage the said shaft. The dasherblades 28 radiate from the lower end of the sleeve 26. Said blades are twisted from a horizontal position at the hub into an inclined position at their outer edges, the lower edges of the blades extending to the rear with respect to the direction of rotation of the dasher. The lower edges 29 of said blades are curved, while the transverse thickness of the upper portions 3() ofthe said blades gradually diminishes toward their upper ends. The ring 31 is attached to the upper ends of the said plates, and the ring 32 is superimposed above the ring 31, it being supported by the pins 33. Both of said rings are of substantially the same dimensions.

The lower end of the dasher-shaft 16 rests in the bearing 34, attached to the bottom of the churn-body 3. Within the churn-body 3 there is provided a plurality of vertical breakers 35. The churn-body 3 is provided with a suitable cover 36. When it is desired to remove the dasher-shaft 16 and dasher from the body of the churn, the screw 25 is removed, which permits the clips 21 to be swung apart, the set-screw 15 is loosened, and the lower end of the pin 14 withdrawn from the recess 17 in the upper end of the dasher-shaft 16. The said shaft may then be tilted forward and removed from the churn-body 3, together with its attachments. To place the said shaft and its attachments within the said churn-body, the operation above described is reversed. When the dasher-shaft 16 and its attachments are properly located within the body 3, it is obvious that by rotating the fly-wheel 5 that the said dasher-shaft 16 and its attach- IOO ments are caused to rotate horizontally. As the said dasher rotates the liquid is forced from the center out toward the churn-body, where it is caused to ascend in the form of a current, being held by the breakers 35, and when it reaches the top it descends through the center of the dasher and continues in this manner so long as the dasher is in motion. In other words, the milk is continually flowing from the dasher-shaft 16 along the bottom of the churn-body 3, up its sides, then toward the dasher-rod and down through the center of the dasher. The course is indicated by the arrows in Fig. l. The rings 31 and 32, located at the upper ends of the dasher-plates 30, serve to maintain the course of the current above described, and by reason of the fact that the upper portion 30 of the dasherblades 28 are gradually diminished in thickness toward their upper ends the said portions do not interfere with the current above described.

By the manner of disposing the rings 31 and 32 with relation to the dasher-blade 28 violent agitation of the cream is eHect-ed. The blades being located entirely below the rings and being formed as specified the cream is drawn down through the rings and is forced downward and outward. It then moves upward, inward, and downward. When it reaches the ring, it is not gently cloven, as would be the case if the said rings were vertically disposed; but it is violently split asunder by reason of the horizontal disposition of the rings, which act as riffles inthe downward course of the cream. By these various agitations separation of the butter from the cream will be rapidly effected without necessitating a great amount of labor.

straight inclined outer edge, a ring connected to the blades at the narrow inclined outer terminal thereof and having all of its sides, edges and surfaces located above the blades, said ring having greater breadth horizontally than thickness vertically, all parts of the said blades being encompassed in a space, the transverse dimension of which is less than the transverse diameter ofthe ring.

2. A rotary churn-dasher consisting of a sleeve, blades attached thereto, each blade having a narrow approximately horizontal inner terminal, a narrow inclined outer terminal and a wide intermediate portion with a straight inclined outer edge, a plurality of rings spaced -apart and connected to the blade at the narrow inclined outer terminal thereof and having all of their sides, edges and surfaces located above said rings and having greater breadth horizontally than thickness vertically, all parts of the blades being encompassed within a space of less transverse dimension than the transverse diameter of the blades.

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

GEORGE WILLIAM HAMILTON.
