CHURN.

SPECIFICATION forming;l part of Letters Patent No. 378,753, dated February 28, 1888.

Application led September 24, 1887. Selial No. 250,590. (No model.)

.To @ZZ whom it may concern:

Be it known that I, JOHN AHRENDs, a citizen of theUnited States, residing at Monmouth, in the county of Crawford and State of Kansas, have invented new and useful Improvements in Churns, of which the following is a specification. y

My invention relates to improvements in churns; and it consists in a certain novel construction and arrangement of parts, fully set forth hereinafter, and specifically pointed out in the claim.

In the accompanying drawings, Figure l is a perspective view of the device. Fig. 2 is a vertical sectional view. Fig. 3 is adetailview of the dasher.

Referring by letter to the drawings, A designates the base of the frame, on which rests the churn-tub B, and to the extremities of the said base are attached the lower ends of the uprights or standards C C.

D designates a cross-bar secured at the ends to the upper ends'of the said uprights and provided at the center with a vertical bearing d, and E represents a vertical shaft journaled in the said bearing and provided on the upper end with the gear-wheel F. The lower end of the vertical shaft E is provided with a fork or yoke, G, the lower extremities of which are secured to the ends of the slotted bar H, provided at the center with thelongitudinal slot h.

I designates a semicircnlar gear-segment pivot-ed to the upper side of the cross-bar D and provided en the inner side of its circumference with gear-teeth to mesh with the teeth of the gear-wheel F. The horizontal plate K extends over the gear-segment and holds the same in place. rIlhe upper end of the vertical shaft E is also journaled in the said horizontal plate. One side of the gear'segment is provided with an ontwardlyextending arm, L. To a block, m, secured to one of the uprights near the upper end is pivoted the lower end of the handle or lever lll, and au intermediate point of the same is connected by the rod N to the extremity of the arm L on the side of the gear-segment. It will now be readily seen that if the upper end of the lever is operated the segment will be rotated, and as the same is geared to the gear-wheel F the vertical shaft will be rotated. Therefore, as the upper end of the lever is moved backward and forward the shaft E will be rotated alternately in opposite directions.

The churn body or tub I3 is provided with a lid, B', which latter has a small opening or bearing, b, in the center.

O designates the dashenshaft, operating in the bearing b and having the upper end fiattened to enter the slot hin the bar H. The upper end of the said dasher is further provided with a perforation, through which is passed the pin or key P to lock the upper end of the dasher to the vertical shaft, whereby when the latter is operated the former will be similarly actuated. To the lower end of the dasher-shaft are secured the radial arms Q, which are arrranged in pairs extending, respectively, in opposite directions. To the extremities of one pair of the said arms are attached the upper ends of the blades It R, angular in cross-section, and to the extremities ofthe other arms are attached the upper ends of the blades S S, which are provided with longitudinalslotsss. Ihe plain and slotted blades are thus arranged alternately, and the effect is to very violently agitate the contents of the tub.

In addition to the four blades just described, there is a fifth blade, T, attached to one of the arms a short distance from the center thereof,

its object being to more eeetually agitate the mill; at the center of the tub.

This churn is exceedingly simple in construction, and it will be found very effective in operation, the gearing being so arranged that the movement of the handle causesa very rapid rotation of the dashershaft, and consequently a violent agitation of the contents of the tub.

Having thus described my invention, I claim@ In a churn, the combination of the uprights C C, cross-bar D at the upper ends thereof, having a bearing, d, in the center, segmental gear I, pivoted to the upper side of the crossbar and having interior gear-teeth, plate K, to hold the segmental gear in place, lever M, pivn oted to one of the uprights and connected to the said segmental gear, vertical shaft E, journaled in the bearing d and having the gearwheel on the upper end tomesh with the segmental gear and the fork or yoke G on the lower end, the slotted bar H, secured to the extremities of the said yoke and having the IOO slot 7L in the center, and the dasher-shaft O, In testimony thatolaimthe foregoing aslmy provided at the lower end with a dasher and own I have hereto affixed my signature in prespassing at the upper end through the slot h, ence of two Witnesses.

the said shaft O being held in place in the slot JOHN AHRENDS. 5 by the key or pin P, passed through a perfo- Vitnesses:

ration therein, substantially as and for the pur- G. M. SLOUGH,
