means being provided whereby when the re-. ceptacle is manually rotated andthen re-,

leased, said receptacle will be rotated in an opposite direction, thereby causing the receptacle and the dashers to oscillate in opposite directions.

A preferred and practical embodiment of the invention is shown in the accompanying drawings, wherein Figure 1 is a central vertical sectional view of the improved churn. Fig. 2 is a horizontal sectional View. Fig. 3 is a detail perspective view of the support for the dash:

ers. Fig. 4 is a detail perspective view of the sleeve that carries the dasher support. Fig. 5 is a detail perspective view of one of the dashers. Fig. 6 is a detail perspective view of the bearing for the operating shaft.

The improved churn comprises a stand including a central vertically arranged bearing 7 from the base of which downwardly inclined arms 8 radiate and terminate in pendent end flanges 9 that overlap and are fastened to the upper ends of the supporting legs 10 that rest on the floor.

A shaft 11 is journaled in bearing 7 and projects through a central opening 12 in the bottom of a churning receptacle 13. A sleeve 14 is centrally disposed in receptacle 13 over opening 12 and has a base flange 15 that is fastened to the bottom of said receptacle. Shaft 11 projects above the upper end of sleeve 14 and a short sleeve 16 is rotatabl fitted over the upper end of sleeve 14 an has a reduced upper end 17 that is keyed or otherwise rigidly fastened to the upper end of said shaft. The lower external portion of sleeve 16 is provided with regularly spaced longitudinally extending ribs 18 having laterally projecting flanges 19 at their lower ends. A dasher supporting sleeve 20 is fitted over sleeve 16 and is provided with regularly spaced internal longitudinal slots 21 with which ribs 18 interlock. Sleeve 20 seats on flanges 19 and has fiat arms 22 radiating therefrom upon which the horizontal dasher bars 23 are fastened. Bars 23 have the spaced blades 24 depending therefrom, said blades being connected by the bars 25. The outer end portions of bars 23 are connected by the brace rods 23*.

A beveled gear 26 is fast on the bottom of receptacle 13 and loosely surrounds shaft 11, said gear being in mesh with a beveled gear 27 that is journaled in a boss 28 that projects laterally from a sleeve129 that is held on shaft 11, by a bracket 29 projecting from bearing 7. Shaft 11 has a beveled gear 30 fast thereon that is in mesh with gear 27. The described gearing obviously causes shaft 11 and receptacle 13 to rotate in opposite directions. Arms 8 of the supporting stand have upstanding eyes 31 at their outer end and said eyes have spring connections 32 with eyes 33 depending from the bottom of receptacle 13. A flanged cover 34 is provided for receptacle l3 and carries hooks 35 that engageeyes 36 to lock said cover to said receptacle. A hand grip 37 is provided for the cover 34. Receptacle 13 has a base drain opening that is normally sealed by a plug 38. Receptacle 13 is also provided with one or more handgrips 39.

In operation, the receptacle 13 is manuually oscillated by grasping the handgrip 39, such movement placing the springs 32 under tension so that when the manual pressure is removed, or reduced, the spring will cause the receptacle to assume its original position. The oscillating movements of receptacle 13, through the gears 26, 27 and 30 oscillate the dashers in directions opposite to the movements of the said receptacle. As will be clear, the spring connections 32 facilitate the oscillations of the receptacle 13.

From the foregoing description it will be clear that the dashers can be readily removed' from sleeve 16;.the spring 32 disconnected from the eyes 31 and 33 and the sleeve 16 disconnected from the shaft 11 so that the receptacle 13 can be readily lifted from the shaft 11. This construct-ion obviously facilitates cleaning, as well as making repairs and substitution of parts.

' vWhat I claim as my invention is 1. A churn comprising a support, a shaft journaled therein, a receptacle provided with a central bottom opening through which said shaft projects, a sleeve carried by and located within said receptacle and surrounding said shaft, a sleeve carried by said shaft and surrounding the upper portion of said first mentioned sleeve, said shaft sleeve being provided with external longitudinal ribs carrying laterally projecting flanges, a dasher supporting sleeve seated on said flanges and provided with internal grooves with which said ribs interlock, arms radiating from said supporting sleeve, dashers carried by said arms, means operated by a rotary movement of the receptacle for rotating the shaft in an opposite direction, and yieldable means opposing rotary movement of said receptacle.

2. A churn comprising a support, a shaft rotatably mounted in said support, a tub provided with a central opening through which said shaft passes, a sleeve leading from said opening and surrounding the inner portion of said shaft, the inner end of said shaft extending above said sleeve, a second sleeve secured to the inner end of said shaft and surrounding said first-mentioned sleeve, dashers connected with said last-mentioned sleeve, means for rotating said tub, and shaft, and springs connecting said tub with said support.

3. A churn comprising a standard, a tub, a shaft mounted in said standard. and passing into said tub, a sleeve surrounding said shaft, a second sleeve connected with said shaft and surrounding said first mentioned sleeve, a collar removably mounted upon said second-mentioned sleeve, and dashers connected with said collar.

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