UNITED STATES PATENT OFFIC ALFRED MORRISON DUNN, OF PLEASANT HILL, MISSOURI.

CHURN.

SPECIFICATION form'ing part of Letters Patent No. 367,797, dated August 9, 1887.

Application filed May 4, 1887. Serial No; 237,124. (No model.)

, following is a specification.

My invention relates to improvements in churns; and it consists in a certain novel con- 1 .struction of parts for service, fully set'fo'rth hereinafter, and specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a front view of a churn embodying my improvements,with the tub or churn-body shown in section. Fig. 2 is a side view of the same.

Fi 5 is adetail section on the line a x of Fig. 1. Fig. 6 is a partial Iearwiew of the churn-operating mechanism to show the ear formed on the rear supporting-bar.

, Referring to the drawings by letter, A designates a collar or band adapted to fit around the upper edge of the churn-body B, and C G D are standards bolted at their lower ends to the said collar and. bent inwardly at the upper ends and secured together, a vertical bearing being formed at the intersection of the said standards to align with. a bearing int-he lid of the churn.

E designates a journal, bolt, or spindle, formed integral with the standard D at its upper end and projecting forwardly therefrom, and on the said spindle is journaled the driv ing-wheel G, having the gear-teeth g 011 the rim and the teeth 9'' on the rear side thereof, near the periphery, a suitable handle, H, be ing attached to the said wheel to operate the same.

1 represents a vertical dasher-shaft journaled in an opening in the churn-lid and the upper part of the frame.

1 is a pinion secured on the upper end of the shaft to mesh with the side gear-teeth, g,

\ of the'power-wheel G, and 1 is a revolving dasher secured to the lower end of the said shaft. At an intermediate point of the said flasher-shaft is arranged a coupling, 2', in which an angular stud, i, .on the end of one portion of the shaft enters an angular recess or socket, i, in the end of the other portion of the shaft,

and is secured therein by the pin i, which is passed therethrough, whereby, when the said pin is drawn out, the dasher will drop into the churn.

K represents'a cross-brace extended between the side standards, 0 C, and in aligned bearings in the said brace; and in the lateral ear K,

on the side of the standard D,is jourualed the horizontal crankshaft L, to the outer. end of which is attached the pinion L, which meshes with therim-tee'th g of the wheel G.

M is a circular vertically-reciprocating dasher having a central opening therein, forming a bearing whereby it may slide on the shaft I, and to the said dasher'is secured the vertical bar N, which passes up through w an opening in thecover of the churn, and is pivotally connected to the lower end of the connecting-link O, the upper end of which is jonrnaled on the crank of the shaft L, so that when the said shaft is rotated by means of the pinion on the end thereof the bar N will be vertically reciprocated.

The pivot-pin n, which passes through the upper bifurcated end of the bar N and the lower end of the connecting-link O to pivotally secure the said members together, is adapted to be withdrawn to allow the dasher attached to the said bar N to drop into the churn.

The operation of my improved churn will be readily understood from the foregoing description. v

W Vhen the power-wheel is rotated the vertical dasher-shaft I is rotated, thereby rotating the dasher I, attached thereto, and at the same time the vertical]y;reciprocating dasher M is operated by means of thecrank-shaft bar and connectinga'od, hereinbefore described, thus violently agitating the contents of the churntub. Vhen the churning has been completed, the pins 12 and i are withdrawn, the dashers thus being dropped into the tub, and the upper part of the churn, or all of the operating mechanism, is lifted off, thus allowing the churn-tub to be easily reached to clean the said dashers.

The improved churn will. be found very strong, durable and effective, and easy to operate.

Having thus described the construction and operation ofmy improved eh urn, what I claim, and desire to secure by Letters Patent of the United States, is

In a churn, the collar A, standards 0 G D, 5 secured at their lower ends thereto and secured together at their upper ends, spindle E, formed integral with the standard D at the upper end, cross-brace K,between the standards 0 C and the ear K on the side of the standard D, com- [0 hi'ned with the vertical shaft I, having the pinion I on the upper end and the dasher l on the lower end, power-wheel G, journaled on the said spindle E, and having the teeth and g thereon,crank-shaft L, jonrnaled in hearings in the said cross-brace K and the ear K, and I 5 having the pinion L thereon, bar N, and the connecting-link 0, attached to the said shaft L and the bar N, and the dasher M on the lower end of the bar N, all constructed and arranged substantially as specified. 20

In testimony that I claim the foregoing as my own I have hereto allixed my signature in presence of two witnesses.

ALFRED MORRISON DUNN.
