CHURN.

- Specification of Letters Patent.

Patented Nov. 25, 1913..

Application filed August 2, 1912, Serial No. 712,903. Renewed June 25, 1913. Serial No. 775,814.

To all whom it may concern:

Be it known that I, THOMAS S. RIGnoN, a citizen of the United States, residing at Ashland, in the parish of Natchitoches and State of Louisiana, have invented certain new and useful Improvements in Churns, of which the following is a specification.

This invention relates to churns and has for its object to provide a simple structure whereby a can of usual cylindrical configuration may be easily and readily used in combination with suitable paddles and appliances for churning purposes.

With the above object in view, the inven tion consists of a frame, which is adapted to be applied about a cylindrical can and which snugly receives the can, whereby the latter is held in position. A detachable block is placed upon the bottom of the can and the lower ends of shafts are journaled in the block. Cap sections are arranged to close the top of the can and the upper ends of the said shafts are journaled in the said sections. The shafts carry at their intermediate portions spaced paddles and the paddles upon one shaft are arranged to move between the paddles of the other shaft as the said paddles are carried around the axes of the shafts. The shafts carry at their upper ends beveled pinions which mesh with a beveled pinion upon the shaft, the shaft in turn being mounted in bearings located at the upper end of the frame. A crank handle or other means is provided for r0- tating the shaft.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing in which:

Figure 1 is a side elevation of the churn. Fig. 2 is a similar view looking at the same at right angles to the view shown in Fig. 1. Fig. 3 is a vertical sectional view of the churn. Fig. 4 is a top plan View of the churn. Fig. 5 is a horizontal sectional view of the churn cut on the line 5-5 of Fig. 3.

Corresponding and like parts are referred to in the'following description and indicated in all of the views of the accompanying drawings by the same reference characters.

The churn includes a cylindrical can 1 of usual pattern. A frame 2 is arranged to snugly receive between its corner posts the said can 1. The corner posts of the frame 2 are provided with rounded surfaces 3 (bestv shown in Figs. 4 and 5) which bear against each side of the pinion. Cap sections 7 fit snugly in the upper end of the can 1 and serve as a cover for the same.

A block 8 rests upon the bottom of the can 1 but is free to be removed therefrom. This block is provided with depressions 9' in which the lower ends of shafts 10 are 1ournaled. The bottoms of the depressions 9 are approximately cone shaped as shown,

while the upper portions of the said depressions are preferably cylindrical. Each shaft 10 is provided at its lower end with a conical head 11, which fits in the conical portion of one of the depressions 9 and each shaft is provided at its lower end with a collar 12? which fits in the cylindrical portion of one of the depressions 9. The collars 12 areloose upon the shafts 10. At their upper 5;.

end portions, the shafts 10 are journaled between the cap sections 7 Paddles 13 are mounted upon the intermediate portions of? the shafts 10 and the said paddles are spaced from each other.

The paddles upon one on} shaft are arranged to move through the spaces between the paddles of the othen shaft as the said shafts rotate. Beveled pmions 14 are mounted at the upper ends of the shafts 10 and mesh with the teeth of the bevel pinion 6. ()nc pinion 14 meshes with the teeth of the pinion 6 at one side, while the other pinion 14 meshes the teeth of the pinion 6 at the opposite side. A handle 15 is mounted upon the shaft 4 or other suitable means may be provided for rotating the said shaft.

In operation the can 1 is placed upon the floor or other flat surface and the block 8 is inserted therein. The shafts 10 are then inserted in the can with their lower ends received within the depressions 9. The cream is then poured into the can and the cap sections 7 are positioned at the top of the can. The frame 2 is then slipped over the can, so that its corner posts snugly receive the can as hereinbefore described. The

7 through the cream.

shaft 4 is then placed in the bearings at the top of the frame and the hinged sections 5 are swung to closed positions and secured. At the time that the shaft 4 is positioned at the top of the frame, the teeth of the beveled pinion 6 are moved into engagement with the teeth of the beveled pinions 14. When the shaft 4 is rotated, the pinion 6 is carried around with the same which in turn rot-ates the pinions 14 in opposite directions. The said pinions 14 turn the shafts 10 in corresponding directions and the paddles 13 are carried around in opposite directions Thus the cream is churned. During the rotation of the shafts 10, the collars 12 bearing against the cylindrical portions of the depressions 9 prevent the shafts from having a tendency to move in lateral directions, while the conical heads 11 serve to reduce the friction between the shafts and the block 8. Furthermore the conical heads 9 serve as means for directing the collars 12 into position in the upper portions of the depresions 9 when the shafts are inserted in the can. fter the churning operation is completed, the parts are disconnected by reversing the steps above described. and after the can has been emptied of its contents, the parts may be thoroughly cleansed: and aired, for the reason that they are disconnected from each other.

By this arrangement it will be seen that a very simple structure is provided for using a can. of usual commercial configuration for churning purposes and that the parts may be easily and quickly separated and disconnected from each other, thereby enhancing the sanitary features of the churn structure as a whole.

Having described my invention, What is claimed as new is:

A churn, including a receptacle having a bearing block in its bot-tom, an upright retaining frame comprising corner posts having inner curved surfaces conforming to the exterior surface of said receptacle, a closure for said receptacle, said frame having its upper end extending some distance beyond the upper end of said receptacle, intergeared dasher-shafts stepped at their lower ends in said bearing block, an actuating member for the intergeared dashershafts, said frame being adapted to he slipped down around said receptacle and embrace it, the lower end of said receptacle resting upon the surface, outside of said receptacle, while the dasher-shaft lower ends rest within said receptacle, the upwardly extended end of said retaining frame having said dasher-shaft actuating member supported thereon, to provide for the removal of said actuating member with the removal of said frame from around said receptacle, and means for the retention of said actuating, member in position upon said frame.

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