`CHURN.

SPECIFICATION forming part of Letters Patent No. 334,586, dated `anuary 19, 1886.

Application tiled September 17, 1885. Serial No. 177,332. (No model.)

.To all whom it may concern: l

Be it known that I, THOMAS H. BESTER, a citizen of the United States, residing at Troy, in the county of Pontotoc and State of Mississippi, havefinvented certain new and useful Improvements in Churns, of which the following is aspeciiication, reference being had therein to the accompanying drawings.

The invention relates to improvements in chui-ns; and it consists in the construction and novel arrangement of parts hereinafter described, and pointed out in the appended claims.

In the accompanying drawings, Figurel represents a central vertical section of the inven tion;. Fig. 2, a central vertical section of the upper part of the saine at right angles to the section shown in Fig. I; and Fig. 3, a perspective view of the ring surmounting the cover, and showing the standards and lugs formed on said ring.

Referring to the accompanying drawings by letter, A designates the body of the churn, preferably of cylindrical form, and having the central circular opening, a, in itscover or lid 4A', which rests on the body, as shown.

Bis a ring surrounding, concentrically, the opening a, and having rising from it, at dianietrically-opposite points, the similar standards, b b; and b b are lugs standing outward from the ring B, midway between said standards.

C is a bar or strip, preferably of plate-metal, crossing the upper surface of the ring B diametrically, with its ends resting upon the lugs b b; and O is a rectangular bracket or frame, of similar mate-rial to the strip C. The middle bar of the bracket is horizontal, and the ends of its vertical legs o bend outward at right angles and rest upon the ends of the strip C.

D D are curved holding-bars, which have their lower ends squared, while their upper ends are rounded and threaded. The upper ends ofthe said bars pass through proper openings in the ends of the strip C and the bracket C', and engage above the same with nuts d d, as shown. The lower ends of the bars pass through rectangular slots in the lugs b', and enter outwardly-curved recesses d in the cover 5o A of the churn-body..

E is a retaining-screw, which passes through an opening in the edge of the cover A', and has its end impinging against one of the bars D, near its lower end.

The ring B, strip C, and bracket C together form a supporting frame, which, with the mechanism secured thereto and hereinafter described, can be quickly and readily attached to and removed from the cover A by means of the bars D, recesses d, and retaining-screw E. This capability constitutes one of the advantages ofthe invention.

F is a `crank-shaft turning in bearings in the upper ends of the standards b, and rotated by the crank-handlef, outside one of its bea-rings. F is a vertical bevelgear turning with said shafts, but having longitudinal movement thereon by tting on a squared portion of the same.

f is a coiled spring between a standard, b, and the bevel-gear on the opposite side of the machine from the crank-handle f.

The vhub G carries a bevel gear-wheel, g', with the teeth projecting downward, and above said wheel g the hub is toothed, as at g. These teeth g are on a bevel, so as to mesh with the gear F. This hub G has bearings on the strip O and in the bar c. The opening through the hub G is squared to receive the squared portion l of the dasher-shaft, as hereinafter described. A

His a vertical pinion meshing with the gearwheel g', and turning on a short shaft, h, which has a single bearing in the lower part of the standard b, adjacent to the crank-handle f.

I is the main shaft of the dasher, which has a portion, z', squared to pass through and turn with the hub G when thelatteris rotated. The upper end of the said shaft is rounded and threaded, and has upon ita nut, t", which rests upon the upper end of the hub G and retains theV dasher-shaft I and attached mechanism connected therewith. This is a second advantage of the invention.

I I are dasher-blades, which stand transversely across the dasher-shaft at equal intervals apart. The said blades incline equally from edge to edge, and are provided with the holes z2, on each side of the shaft I, which iS secured centrally t0 each blade.

ICO

I3 is a circumferential shoulder on theshaft Lashort distance below the cover A.

j is the transverse bar ofthe dasherframe J.

K K are side bars of the frame J, which bars depend from the ends of the bar j, and have standing inward from them at regular intervals the dasher-blades k k, provided with the holes It. The said blades registerbetween the blades I', so as not to strike the latter when passing.

L is a bevel crown-wheel, which turnsloosely upon the shaft I, and has its lower boss secured to the barj, as shown. IThis boss or hub rests on the shoulder Ii. The said crown-wheel u has its teeth upon its uppersurface and meshesv with the pinion H, so that when the shaftlis rotated in one direction, by means ofthe wheel F', pinion g, and hub G, the coaction of the wheel g', pinion H, and wheel L will rotate the dasher-frame J in the opposite direction, and cause the blades I and K to pass mutually between each other, thus effectively stirring up and beating the milk. The holes z2 and it aid this action by causing counter-currents in the milk as it flows through them.

To quickly take apart the machine, the nut i is removed, detaching the dasher-shaft I, dasher-fraine J, and wheel L from the parts of the mechanism connected to the frame coinposed ofthe ring B, strip C, and bracket C. The retaining-screw E is then unscrewed, and the said frame and attached mechanism removed from the cover A. rlhen, by removing the cover, the dasher mechanism can beliftcd out ofthe churn for examination or repair.

Having described my invention, I claima l. The combination of the churn-body havA ing the cover provided with the recesses d', curving downwardly and outwardly,the frame composed of the ring, the standards, the diametrical strip, and the bracket having the dasher-actuating mechanism attached to it and provided with the curved bars D, which bind its parts together and enter the recesses d', and the retaining-screw E, which passes through a proper opening in the cover of the churn and enables the frame and attached mechanism to be quickly and readilyattached to or removed from the churn-cover, substantially as specified.

2. The combination ofthe churnfbody provided with a cover, A, having a frame and attached dasher-actuating mechanism, substantially as described, detachably secured to it, and a dasher mechanism, substantially as described, provided with a central vertical shaft, I, having its upper end threaded and passing through one of the horizontal gearwheels of the dasher-aetuating mechanism and retained in connection therewith by means of a nut, i, on its threaded end bearing uponthe top of the said horizontal gear, so that by removing said nut the dasher mechanism and dasher-actuatiug mechanism can be quickly and readily separated, substantially as specified.

3. The combination of the churn-body provided with the cover A, the frame composed of the ring B, strip C, and bracket C', the bars D, retaining-screw E, crank-shaft F, hub G, and gear-wheels F, g, g, and H, with the dasher-shaft I, provided with the blades I, squared portion i, and shoulder l", nut i', and dasher-frame J, composed of the transverse bar j, and vertical bars k, provided with the blades k', all constructed and arranged substantially as shown and describechfor the purpose specified.

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

THOMAS H. HESTER.
