To all whom it may concern Be it known that I, CHRISTOPHER Aunrr,k a citizen of the United States of America, residing at Rock Valley, in the county of Sioux and State of Iowa, have invented certain new and useful Improvements in Churns, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a churn and has for its object the production of a simple and efficient means for supporting the churn body within the casing.

Another object of this invention is the production of an operating mechanism which is carried by the top of the casing so as to be easily swung into engagement with the dasher and churn body, when so desired.

lith these and other objects in view this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing: Figure 1 is a perspective view of the churn, a portion of the same being broken away. Fig. 2 is a central vertical section of the churn. Fig. 3 is a transverse section taken through the device. Fig. 4 is a central vertical section taken through the upper portion of the device at right angles to Fig. 2. Fig. 5 is a perspective view of the operating shaft. Fig. 6 is a. perspective view of a portion of the operating shaft and dasher.

Referring to the accompanying drawing by numerals 1 designates a casing having the supporting cleats 2 which are adapted to support the floor 3. The upper portion of the casing 1 is provided with the reinforced cleats 4 and with the hingedly secured top 5, this top 5 being held in position by the hinges 6. The floor 3 is provided with the pivotally secured lugs 7 which are provided with the concave inner faces 8 for fitting upon a churn body 9 for securing this churn body in a central position within the casing 1. By having a lug 7 pivotally mounted it will be seen that the churn body 9 will be easily placed within the casing 1 as the lugs 7 will easily swing for accommodating the churn body. This churn body 9 is provided upon its upper end with the sectional cover 10 having a sight opening 11 which may be covered with glass to allow a person to view Specicaton of Letters Patent.

serial No. 767,882.

the interior of the body without necessitating the removal of the sectional cover 10. This cover is provided with the opening 12 which is adapted to allow the upper portion of the dasher 13 to extend therethrough, the lower portion of this dasher being supported by the lower portion of the pocket 14 carried by the interior of the churn body 9. This dasher 13 is provided with a plurality of transverse arms 15 for agitating the milk within the churn body. This body is also provided with an opening 16 and a stopper 17 whereby the milk may be allowed to iow from the interior of the body when desired. In this manner it will be seen that the dasher 13 may be held in a central position within the churn body 9 for allowing the same to be rotated when desired.

The top 5 is provided with an opening 18 formed in the central portion thereof. A supporting bridge 19 is also carried by the top 5 so as to be positioned over the opening 18. This supporting bridge 19 is provided with a pocket 2O which is positioned directly above the opening 18, this pocket 2O being provided with a flat upper face 21.

An aperture 22 is formed in the supporting bridge 19 above the opening 18 so as to allow the operating shaft 23 to extend through the aperture 22 and opening 18 for communicating with the interior of the casing 1. This operating shaft 23 is provided upon its upper end with a pulley 24 having an enlarged flange 25. A belt 26 may be placed on the pulley 24 for rotating the same, while the flange 25 will prevent the belt 26 from sliding o the pulley. A washer 27 is mounted upon the upper portion of the supporting bridge 19 for reducing the friction between the pulley and the bridge. In order to hold this pulley 24 upon the operating shaft there is provided a pair of locking nuts 28 which are carried by the threaded end 30 of the operating shaft 23. In order to limit the upward movement of the operating shaft 23 there is provided a transverse pin 31 which passes through the transverse aperture 32 formed in the operating shaft 23. In this manner it will be seen that the operating shaft 23 will be held firmly in position upon the supporting bridge 19 whereby the same may be easily rotated while the transverse pin 31 will prevent the shaft from being removed therefrom. It will also be seen that by havsov ing the flattened portion 2l formed in the supporting bridge 197 the transverse pin 31 will be allowed to rotate freely without striking any roughened portions. The lower portion of the operating shaft 23 is provided with a transverse pin 33 passing through the transverse opening 34. The upper end of the dasher 13 is provided with a sleeve 35 having a central transverse partition or web 36 that seats upon the upper end of the dasher 13 and also serves to prevent the lower end of shaft 30 contacting with the upper end of said dasher. This sleeve 35 is held in fixed engagement with the dasher 13 by means of the rivet 37 or any other suitable attaching means. The upper portion of this sleeve'35 is provided with the alined notches 38 for receiving the transverse pin 33 whereby when the shaft 23 is rotated, the dasher 13 will also be turned. When this device is being used, the hasp 39 which is carried by the bridge 19 may be secured to the keeper 40 carried by one of the bracing cleats 4 for holding the top 5 securely upon the upper portion of the casing l. Vhen this device is used, the churn body 9 is positioned within the casing l so as to be held in position by means of the lugs 7. The top 5 may be swung to a closed position so as to allow the transverse pin 33 to rest Within the alined notches 38 formed in the sleeve 35. Then by rotating the pulley 24 the shaft 23 will impart rotary motion to the dasher 13 for churning the milk within the body 9. When it is desired to remove the churn body 9, by swinging the top 5 upwardly it will be seen that the pin 33 will become disengaged from the sleeve 35 whereby access may be easily had to the churn body.

F rom the foregoing description, it will be seen that an efficient churn has been produced which is provided with a simple means for operating the same. This operating means detachably engages the dasher whereby the dasher may be rotated or the operating means may be removed when it is desired.

Having thus described the invention, what is claimed as new, is

A churn comprising a casing having a hinged top provided with a central opening, an arch-like bridge carried by said top, said bridge provided with a centrally arranged oeket having a flat inner face said bridge f also provided with a vertical aperture positioned above the opening formed in said top, a shaft passing through the aperture formed in said bridge and extending downwardly into said casing, a driving pulley fixedly secured to the upper end of said shaft and bearing upon said bridge thereby limiting the downward movement of said shaft, a transverse pin carried by said shaft and positioned within said pocket, said pin bearing upon the flat face of said pocket thereby allowing said shaft to freely rotate and also eliminating any upward movement of said shaft, said shaft adapted to rotate a churn dasher.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
