CHURN.

Specification of Letters Patent.

Application filed May 14, 1909.

Patented June '7, 1910. Serial No. 495,946.

To all whom it may concern:

Be it known that I, JAMES D. citizen of the United States, residing at Grubbs, in the county of Jackson and State of Arkansas, have invented new and useful Improvements in Churns, of which the following is a specification.

This invention relates to churns and the object of the invention is to provide a sim ple and effective device which may be attached to any ordinary tub having its mouth provided with a bead, and which has its parts so arranged and constructed as to quickly and easily churn the cream to butter.

With the above and other objects in view which will appear as the description progresses the invention resides in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawing there has been illustrated a simple and preferred embodiment of the invention and in which,

Figure l is a partial side elevation of a churn tub constructed in accordance with the present invention. Fig. 2 is a top plan view of the same. Fig. 3 is a perspective view of the resilient connecting rlng employed with the device.

In the drawing the numeral 1 designates the tub of the churn. This tub 1 need be of no particular construction, as any ordi nary jar having its up er extremity provided with a bead or 0 set 2, may be employed. The tub 1 is however provided upon its base with a central non-cylindrical opening 3, the purpose of which will hereinafter be set forth.

The numeral 4. designates the head or cover of the churn. This head 4 is preferably constructed in two sections designated by the numerals 5 and 6 and these sections are hingedly connected together as indicated by the numerals 7. Mounted upon the member 5 of the head 4 is a suitable arbor 8. This arbor 8 has its upwardly projecting arm provided with an opening adapted for the reception of a shaft 9 which is connected with a crown geared wheel 10. This wheel 10 is provided with a suitable handle 11 and is adapted to mesh with an idler sprocket wheel 12 mounted in suitable bearing within the section 5 of the top. The arbor 8 is provided with flattened extending arms or members each of which having their ex- TUCKER, a

tremities provided with openings and which are adapted to provide bearings for a pair of sprockets 13 and 14. These sprockets 13 and 14 are adapted to mesh with the sprocket 12 so that upon revolving the crown geared wheel 10, the said sprockets 13 and 14:, will, through the medium of the idler sprocket 12 revolve in opposite directions.

The numeral 15 designates the resilient connecting ring employed with the improvement. This member 15 is split and is provided with projecting arms 16, each of which being provided with alining openings one being threaded and adapted for the reception of a threaded securing element 17. The ring 15 is preferably provided with an offset projection 18 upon its lower extremity and this oifset 18 is adapted to engage beneath the under face of the head 2 provided upon the tub 1.

The numeral 19 represents the hinged locking members. These members are preferably constructed of a single strand of wire bent at its extremities in opposite directions to engage with suitable eyes 20 provided upon the top 4:. The engaging members 20 are bent forwardly over the top 4 and from thence bent downwardly in a vertical direction and provided with lips 21. These lips 21 are adapted to engage the underface of the ring 15, which is preferably inclined or beveled as clearly illustrated in Fig. l of the drawings. By arranging the elements 19 as above described, it will be noted that the resilient connecting ring may be at all times retained upon the top 4, and that by merely operating the screw threaded member 17, the ring will spread outwardly a suitable distance to allow the same to be positioned upon the offset 2 of the tub 1, the said members 19 swinging upon their pivots to accommodate this movement, before the ring is brought into engaged position a flexible ring washer 22 is positioned upon the upper wall of the tub 1 so as to provide an air tight joint when the top is connected with the tub.

The numeral 23 designates a rectangular frame having centrally arranged pintles, one secured to the arbor 8 and the lower pintle positioned within the opening 3 provided in the bottom of the churn. Secured to the cog wheels 13 and 14: and passing through suitable openings provided in the top and bottom arms of the frame 23 are shafts 24c and 25. These shafts 25 are adapted for the reception of horizontal arms of the rectangular dasher members 26 and 27. The dasher members 26 and 27 are each arranged at a substantially right angle to each other and as previously stated the cog wheels 13 and 14: revolve in opposite directions, thus causing the shafts 24 and 25 carrying the dashers 26 and 27 to also revolve in opposite directions.

From the above description, taken in connection with the accompanying drawing it will be noted that I have provided an extremely simple and cheap operating mechanism for churn tubs, one which may be quickly and easily applied to any ordinary churn tub having its mouth provided with a bead and one which has its dasher members so constructed and arranged as to rapidly break the globules of the cream causing the same to quickly churn.

Having thus fully described the invention what is claimed as new is:

In combination with a churn tub having an offset mouth, of an L-shaped split ring engaging said mouth, a securing element for the ring, a cover for the tub, said cover comprising a pair of sections hingedly connected together and one of said sections being larger than the second section, both of said sections being adapted for the reception of dasher operating mechanism, and ofiset hooks upon both of the cover sections adapted to be swung into engagement with the L-lsjhaped ring to retain the cover upon the tu In testimony whereof I aflix my signature in presence of two Witnesses.
