C l-i U R N SPECIFICATTON formngpart of Letters Patent No. 701,304, dated June 3, 1902.

Application led January 20,1902. Serial No. 90,384. (No model.)

To all whom it may con/cern:

Be it known that l, OLAUS A. DAI-IL, a citizen of the United States, residing at Nash, in the county of Valsh and State of North Dakota, have invented certain new and nsef ul Improvements in Ohurns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention has fr its object to provide an improved churn of simple construction and a high efficiency, and is especially directed to churning mechanism which is adapted for ready application to ordinary earthen jars for quickly churning comparatively small amounts of butter.

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described, and dened in the claim.

My invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a vertical section taken centrally through a jar and one of my improved churning attachments applied thereto in working position. Fig. 2 is a horizontal section on the line m2 c2 of Fig. 1. Fig. 3 is a horizontal section on the line :t3 :r3 of Fig. 1. Fig. 1.1. is a detail in vertical section taken on the line 064004 of Fig. 2. Fig. 5 is a detail view in side elevation, showing a portion of the beater-shaft and one of the beater-blades; and Fig. 6 is a vertical section on the line m5 50G of Fig. 5.

The numeral 1 indicates an ordinary earthen jar having at its upper edge an outwardly-projecting marginal bead 2.

The numeral 3 indicates a vertical standard or hollow bearing, to the lower end of which is rigidly secured a supporting-base afforded by a plurality of supporting-arms 4, the outer ends of which are turned downward, as best shown at 5 in Fig. 4, so that they underlap the marginal bead 2 of the jar 1. These depending clamp-sections 5 are embraced by a split clamping-ring 6, theends of which are drawn together bya short nntted bolt 8, as best shown in Fig. 2. By said clamp the sections 5 are tightly drawn against the jar, and the arms 4e and standard 3 are thereby securely anchored to the jar, with the said standard projecting verticallyin line with the axis of said jar. A flat disk-like jar-cover 9 is secured to the base end of the standard 3i, just below the arms 4. Both said arms and. said cover are thus rigidly secured to the standard 3 by a pair of opposing clamping-nuts 10. To enable the operator to inspect the contents of the jar from time to time in the process of churning, said cover 9 is provided with a hinged sight-hole cover 11.

The beater-shaft 12 is mounted in and supported by the standard 3, and its downward movement is limited by a collar 13 on the upper end thereof, which engages the upper end of said standard. The lower end of said shaft 12 depends into the jar 1, nearly to the bottom thereof. This depending portion of the shaft 12 is preferably square and provided with tapered dovetailed seats la. The beater blades or'arms 15, which extend horizontally and radially of the said beater-shaft, are provided at their central portions with tapered dovetailed sections 15, which fit in the seats la of the depending end of the shaft 12. This construction permits the beater blades or arms to be readily detached for the purpose of cleaning and then to be quickly applied again in working position simply by driving them endwise in the proper direction.

To the eXtreme upper end of the shaft 12 is applied a pinion 16. A gear 17, having a handpiece 18, meshes with the pinion 16 and imparts a relatively high motion thereto. This gear 17 is loosely mounted on the stud 19 of a hub 20, which hub is adjustably se cured on the upper end of the standard 3 by a set-screw` 21 or in any other suitable way.

As is evident, when the attachment is apd `plied to the jar, as indicated in Fig. 1., the

jar is tightly closed and the cover 9 and .arms 4c cooperate to rigidly support the standard 3. As is obvious, a high motion may be imparted to the beater by means of the driving-gear described. It is also evident that the standard, the jar-cover, the beater, and its driving gear are all removable together from the jar. This is important, as no adjustments are required for applying the attachment to the jar and no loose parts are necessary to afford a suitable support for the beater and its shaft.

IOC)

It Will of course be understood that the device may be applied to a jar or tank of any desired size, although the construction is espeoially adapted for light Work and for applioation to jars of such size as Will afford a small churn. It Will be further understood that the device described is capable of some modification within the scope of my invention as herein claimed.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

The combination with a jar l having the marginal head 2, of the standard 3, the supporting-armsi and jar-cover 9 secured to the base end of said standard, by the clampingnuts l0, which arms 4 have the depending clamping ends 5, the beater-shaft l2 mounted in said standard and provided at its dependinf,r end with radial beater-arms, the pinion on the upper end of said shaft l2, and the crankequipped gear meshing With said pinion and mounted on a bearing carried by said sleeve 3, substantially as described.

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

OLAUS A. DAHL.
