PATENT I LID-.CLAMP FOR CHURNS.

SPECIFICATION forming part of Letters Patent No. 372,853, dated November 8, 1887.

Application led May 26, 1887. Serial No. 239,464. (No model.)

To all whom it mayA concern:

Be it known that I, Louis K. KooNrz, a citizen of the United States, residing at Gross Lanes, in the county of Nicholas and State of West Virginia, have invented a new and useful Improvement in Clamps for Churn-Lids, of which the following is a specication.

My invention relates to an improvement in churns,and especially to lid-clamps; and it consists in the construction and arrangement of the parts thereof, which will be more fully hereinafter described, and pointed out in the claim.

In the drawings hereto annexed, Figure lis a side view of the churn. Fig. 2 is a vertical section thereof. Fig. 3 is adetail view of the dasher. Fig. 4 is a similar view of the clamp.

Referring by letter to the drawings, A designates astone churn-tub, which ordinarily is provided around the upper edge with a flared rim, a.,an,d Bis a wooden top therefor, to which is attached the operating mechanism of the churn.

-C designates the standard, having a horizontal arm, o, which is firmly secured to the top B, and having a vertical bearing, c', therein.

D is the upright, havinga bracket, d, on the outer side near the center, and aligned horizontal bearings D d are 'formed in the said upright and bracket, for a purpose hereinafter explained. The upper end of the upright is reduced to form a stud, e, threaded at the upper end, and the horizontal arm E is provided with a depending ear, E', adapted to bear on the outer side of the said upright. The said arm E also has a vertical aperture, e', to receive the said stud e. A nut is screwed on the upper end of the said stud, thus rigidly securing the horizontal arm E in place, and

4o f represents a vertical bearing formed in the outer end of the said arm.

G designatesa vertical tubular shaft adapted to operate in the vertical bearing c', and having a collar, g, to rest on the upper side of the horizontal arm c, and the miter gear-wheel G.

H designates a shaft of the same size as the tubular shaft G, having a lower reduced portion, h, to pass down through and extend a considerable distance below the lower end of the said tubular shaft. A pintle, h', is formed on the upper end of the shaft H to operate in the bearing f, and a miter gear-wheel, H', similar to the wheel G, is secured on the said shaft.

I designates a shaft journaled in the bearings d D' on the standard, having the large gear-wheel I on the inner end to mesh at opposite sides with the gear-wheels G and H', and the crank-arm K on the outer end to enable the said gear-wheel to berotated. It will be readily seen that when the gear-wheel I is turned the gears G and H will be rotated in opposite directions.

L designates the dasher of the churn,which is double, and consists of the two paddles M and N. The inner and smaller paddle, M, comprises-the radial arms M at the upper and lower ends of the same, secured rigidly to squared portions of the reduced shaft h,which extends below the tubular shaft G, and m m are blades of the paddles reduced at the ends and set in inclined slots in the ends of the said radial arms. j

The outer and larger paddle, N, has the radial arms N at the upper and lower ends thereof, the upper arms being rigidly secured to the lower end of the tubular shaft G, and the lower arms being provided with a bearing to operate on the lower end of the shaft h. The blades a n are secured in the said radial arms in the same manner as in the other paddle, and thus hold the parts of the paddle together. The said blades m and n are so arranged in the paddles that the outer blades draw the milk or other contents of the tub inwardly toward the center, and the blades on the inner paddle throw the said contents outwardly. This action causes great agitation of the said contents, especially as the said paddles move in opposite directions.

To secure the top of the churn firmly on the tub I provide the following means: O designates'a clamp having the straight arm O', bifurcated to form the prongs O2 O2.- The outer end of the straightarm is bent downwardly to form the depending arm P, having a transverse threaded opening, p, in the lower end to receive the thumb-screw Q, and the extremities of the prongs O'l are bent downwardly and formed into hooks R. Thestraight arm O and the prongs O2 are placed across the upper side of the top, and the hooks R pass around the ICC edge of the said top and vbear against the side of the tub. When the thumb screw Q is screwed in, the inner end thereofwill impinge against the opposite side of the said tub from the ends of the hooks R and hold the clamp firmly in position. As it is usual for the upper edge of the tub to be flared, as seen in the drawings, it will be readily understood that the tendency of the clamp will he to draw down upon the lid, as the ends of the hooks and screw will slip down on the said dared portion. It is not necessary, however, that the edge of the tub should be flared in order to make the clamp operative, as it will hold the lid rrnly in plaeeon any ordinary tub, Whether of wood, Stone, or other material.

The standard for the operating mechanism herein described is designed to be light and strong, to enable it to be easily moved, and at the same time to be rigid While the churn is being operated.

The dasher is designed to be easily and cheaply made, and to have strength and great eiectiveness. The action of the parts thereof in opposite directions,with the blades arranged to violently agitate the contents of the tub, as hereinbei'ore described, will cause the butter to be very quickly separated.

The clamp herein described is very effective and applicable to any churn. The said clamp is also very easily applied to a churn.

Having thus described the construction, op eration, and advantages of my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

In combinationwith aehnrn having a flared upper edge, a lid, B, and a vertical shaft, of the clamp O, adapted tohearon the upper side of the lid and comprising the main body or straight arm O', the integral diverging arms O2 O2, passing on opposite sides of the said vertical shaft, the downwardly-turned bearinghooks R on the extremities of the arms O, adapted to engage the flared edge of one side of the churn, and the depending arm P, formed with the extremity of the straight arm O,and having a thumb-screw, Q, passing through a tapped opening therein and engaging with opposite sides of the churn, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aiiflxedmy signatures in presence of two Witnesses.
