Application filed June 3, 1922. Serial No. 565,629.

To all whom it may concern: 7

Be it known that I, MCBRIDE L. KELLY, a citizen of the United States, residingat Thomasville, in the county of Thomas and State of Georgia, have invented new and useful Improvements in Ghurns, of which the following is a specification.

In carrying out the present invention it is my purpose to improve and simplify the general construction of churns and to provide a churn wherein the agitators may be readily and quickly disassembled when it is desired to clean or repair the same and eX- peditiously assembled.

It is also my purpose to provide a. churn wherein the operating mechanism will embrace the desired features of simplicity, efliciency and durability and which will be constructed in such manner that access may be had to all the parts for the purposes of repairing, cleaning, etc.

With the above recited objects in view, and others of a like nature, the invention -resides in theconstruction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings:

Figure 1 is a view in side elevation of a churn constructed in accordance with my invention.

Figure 2 is a vertical sectional view therethrough.

Figure 3 is a top plan view of the same.

Figure 4: is a sectional view on the line i e of Figure 1.

Figure 5 is a horizontal sectional view on the line 5-5 of Figure 1. 7

Referring now to the drawings in detail, 1 designates the container or receptacle which is preferably formed of glass and is provided at its upper end with a neck 2 that is externally threaded. Threaded onto the neck 2 is a cap 3 formed of metal or other suitable material and provided centrally with an opening.

Mounted upon the cap 3 and suitably secured thereto is a frame 4 comprising a bottom member 5 that'is formed with an opening alining with the opening in the cap and with an' upstanding collar 6 concen- 13111321115 01 the opening therein. Upstandmg from the ends of the bottom member 5 are arms 7 and 8, respectively. The arm 7 j is preferably arranged at an acute angle to the bottom 5 and is equipped at itsupper end with a bearing collar 9 that alines axially with the opening in the top 3 and the opening in the bottom member 5.

The upper end of the arm 8 and the confronting portion of the collar 9 on the arm 7 are formed with axially alining bearings and inthese bearings is'journaled a shaft 10, the outer end of which is provided with a crank handle 11 by which the shaft may be revolved. Encirclingthe-shaft' 10 is a spring 12 having its inner end fixed to the shaft. Loosely mounted upon the shaft 10 adjacent to the inner end thereof is a beveled gear 13 equipped with a pin 14: adjacent to its periphery and to the pin leis connected the outer end of the convoluted spring 12. Fixed to theshaft 10 at the other side of the spring 12 is a ratchet wheel or pinion 15 and engaging the ratchet wheel or pinion 15 is a spring pressed dog 16 that is pivoted as at 17 upon the arm 8. The spring 12 and the dog and pinion are encased in a cupsh'aped-housing 18 that is carried by the arm 8 and the open end of the housing is closed, or substantially closed, by the rear side of the beveled gear 13,. so as to protect the spring, and pinion and dog from dust, dirt, grit and other foreign matter.

The collar 9 is also equipped with a spring pressed pin 19engageable in any one of a series of notches 20 formed in the outer face of the beveled gear 13, the pin acting to hold the beveled gear 13 normally against rotation under the actionof the spring 12. j By means of the construction just described, it will be seen that when-the shaft 10 is rotated under the action of the handle 11, while the pin 19 is in engagement with the adjacent notch20, in the gear 13, the spring 12 will be placed under tension and retrograde movement of the shaft will be prevented by the ratchet and dog 15 and 16. When the pin 19 is withdrawn from engage ment with the corresponding notch, then the spring 12 is released and reacts to revolve the beveled gear 13.

Rotatably mounted in the alining openings in the cap 3 and member 5 is a tubular collar 21, and suitably connected to the upper end of the collar 21 is a beveled pinion 22 meshing with the beveled gear 13. Journaled in the bearing collar 9 and extending through the center of the pinion 22 is a vertical shaft 23. 'On the'upper end of the shaft 23 is fixed a beveled pinion 24 meshing with the beveled gear 13 at a point diametrically opposite the-point of contact between the gear 13 and the opening 22. The'lower end ,ofthe shaft 23 extends a short distance below the tubular collar 21 and is externally threaded, and threaded onto the lower end of the shaft 23 is the upper end of an agitator shaft 25 carrying adjacent to its lower end agitating arms 26. Immediately above the agitating arms 26 the shaft 25 is equipped with a collar 27. Arranged concentrically of the shaft 25 above the collar 27 is a tubular shaft 28 that carries agitating arms 29. The upper end of the tubular shaft 28 interlocks with the lower end of the tubularcollar 21, as at 30, while the lower end of the tubular shaft 29 is engaged by the collar 27 on the shaft 25, so that the tubular shaft will be held connected to the collar 21 and to the pinion 22.

In practice, when the pin 19 is with drawn from engagement with the corresponding notch 20 and the spring reacts to rotate the gear 1.3, the latter transmits mo tionv through the pinion24 to the shaft 25 and through the opening 22 to the shaft 28, thereby reversing the shafts and 28 in relatively reverse directions, so as to churn the contents of the receptacle 1.

In the present instance, the upper end of the bearing collar 9 is formed with an upst'anding circular flai'ige 31 arranged concentrically of the shaft and adapted to be engaged by'brake arms 32 pivoted to a collar 8S at diametrically opposite points, the collar 33 being carried by the shaft 23 and fixed to such shaft immediately below the pinion 2%, as clearly shown in Figure 2 of the drawings. The arms 32 are normally held against outward movement under ac tion of centrifugal force by a spring 3%.

Should. the speed of the shafts increase abnormally the brake arms 32 fly upwardly under the action of centrifugal force and so engage the flange 81, thereby checking the too rapid rotation of the shafts.

lVhile I have herein shown and described one preferred form of my invention by way of illustration I wish it to be understood that I do not limit or confine myself to the precise details ofconstruction herein shown and described, as modifications and variations may be made within the scope of the claims and without departing from the spirit of my invention.
