T 0 all whomz't may concern: Be it known that I, EZEKIEL N. PARIS, a

citizen of the United States, residing at for an object to provide a churn having im-' proved means for controlling the cream within the receptacle both as to its agitation and the controlling of the temperature of such cream.

A further object of the invention is to provide a churn having reversely rotating dashers of the propeller type with an interme-' diate member for cutting the cream, performing a function not performed by the dashers as shown, or as ordinarily employed.

A further object of the invention is to provide beneath the receptacle a compartment employed for controlling the temperature of the cream by the installation therein of a heating element if the temperature should be raised, or acooling material if the temperature should be lowered.

With these and other objects in view the invention comprises certain novel features, elements, units, parts, combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a diametrical sectional view of the improved churn;

Fig. 2 is a transverse sectional View taken on line 2--2 of Fig. 1;

Fig. 3 is a detail sectional View taken on the mounting of one of the dashers, and

Fig. 4 is a detail perspective viewof the cutting element.

Like characters of reference indicate cor. responding parts throughout the several views.

The improved churn which forms the subject matter of this invention comprises a receptacle, or container, 10, of any usual or ordinary shape, configuration, or size, here shown as cylindrical and with a verticalaxis.

The container is provided with a bottom 11 and is supported in any approved manner, as by the feet 12. A cover member 13 is provided, and while preferably this cover Specification of Letters Patent.

member will be in sections, such sectional formation is not essential to the present invention. The cover member is provided with a screw cap 14, carrying a thermometer 15, by which the temperature of the contents may be read from the exterior.

Within the receptacle 10 a hollow shaft 16 is mounted, extending upwardly through the cover member 13 and provided with a beveled pinion 17 intergeared by the beveled gear 18, actuated in any approved manner, as by the crank 19. At the lower end, the tubular shaft 16 is provided with a hub 20, secured thereto in any approved manner, as by the set screw 21, and such hub member is provided with the dasher arms 22, which are reversely inclined, similar to the inclinations of a conventional propeller. At the lower end the tubular shaft 10 is provided with a bushing 23, through which extends the shaft 24. The shaft 24 is provided at its upper end with a beveled pinion 25, intergeared wlth a gear 18, and a bracket 26 is located upon the cover member 13, forming a bearmg for the upper end of the shaft 24. The bottom 11 is provided with a bearing 27 supporting the lower end of the shaft 24. It will be noted from Fig. 1 that the shafts 16 and 24 will be rotated in the opposite direction bythe rotation of the gear 18. The shaft 24 is provided with a hub 28 secured thereto in any approved manner, as by the set screw 29, and carrying dasher blades 30, which, like the dasher blades 22, are reversely inclined and their inclination such as to move the contents in opposition to the movement provided by the blades 22. The action of the blades 30 is to move the contained cream upwardly, while the action of the blades 22 is to, move it downwardly. This forms an agitation between the blades, forming a zone of quiet. This zone of quiet is transected by a cutter 31, which is made substantially in the form of wire with coils 32, shown as three in number, but the invention is in no way limited to the number of coils so employed.

The cutter 31 is carried upon the hub 33, which is secured to the shaft 24 in any approved manner, as by the set screw 34. A drain cock 35 communicates with the receptacle 10, from and through which the buttermilk may be discharged after the churning has been completed.

Beneath the bottom 11 is a receptacle 36,

which is adapted to support a medium for varying the temperature of the contained cream. As shown at Fig. 1, a lamp-like structure 37 is employed, but it is to be understood that this is not limited in any man ner to such particular element, and any a cooling element is fully Within the scope of the present invention.-

It is believed that the operation and function of the severalparts and their combinations will berfully understood from the foregoing.

What I claim to be new is: In a churn having a vertical spindle, a

blade structure comprising a socket adapt- 20 the spindle, means for retainlngthe rod immovably in thesocket, the rod bent into a plurality of loops and aflixed With the loops having their axes on chords of a circle having the axis of the spindleas their center. In testimony whereof I hereuntoafiix my signature in presence of tWo Witnesses.
