T0 @ZZ whom, :it may concern:

Be it known that I, CHARLES RAW, of Graytown, county of Ottowa', State of Ohio, have invented new and useful Improvements in Butter-Churns; and I do hereby declare that the following is a full, clear, and'eXact description of the invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form part of this specification.

My invention relates to a butter-chu rn, and has for its object to provide a stoneware crock having formed upon its edge a concentric ring projecting outward beyond the edges thereof and form upon the under side of the ring a concentric upwardlyprojecting groove, whereby the closure-plate having the driving mechanism mounted thereonimay be readily and tightly secured to the crock, and which closure-plate, together with the mechanism for fastening the same to the churnbody and the driving mechanism mounted thereon, may be veasily and quickly removed from the churn-body, leaving a regular stoneware crock without mechanism or metal fastened thereto.

A further object is to provide adrivingcrank adapted to be removably mounted upon the driving-arbor.

The invention further consists of the elements hereinafter described and referred to.

In the drawings, Figure l is a perspectivel View of my invention with the churn-wall partially broken through to show interior. Fig. 2 is a longitudinalsection through a churn constructed in accordance with my inven tion. Fig. 3 is a cross-section on the line a: w, Fig. 2. Fig. 4 is a top plan view of the churn-body, and Fig. 5 is a fron televation of a locking-bolt. p

The object of my invention is accomplished by providing a stoneware crockmolded, preferably, to the form of churn-tubs now in use, and by constructing the tub out of stoneware I have found that a butter may be produced of a sweet odor and the tub can be more easily and thoroughly cleaned.

I have found that in a churn-tub constructed of wood the butyraceous fluids more or less permeate the wood through its pores, causing an odor to eminatetherefrom even after repeated scourings, whichaect and contaminate fresh butyric globules formed in the tub by churning and which objection is wholly obviated by my invention. I have also found' that a stoneware crock having ears formed upon its sides is difficult to handle, as it cannot be rolled without the danger of nicking or breaking 0E the ears, and, further, that the ears weaken the crock at the point of adhesion, which objections are obviated by my invention, a concentric ring being less easily broken than ears. A concentric ring has the further functions of a hoop or strengthening-ridge and of being used as a grip or handle for lifting purposes. I have also foundthat a crock constructed in accordance with my invention may be more thoroughly and easily cleaned than one having ears and means for fastening the cover permanently secured to such ears.

l designates a churn-crock molded in aecordance with my invention and provided with a concentric enlarged rim 2, which has formed upon its under side an upwardly-pro jecting groove 3. The closure 4t has secured thereon in a central position a journal-plate 5, in which are revolubly mountedthe horizontal driving-arbor 6 and a vertical driven arbor 7. Motion is transmitted from the driving to the driven arbor by means of intera meshing mitergearsS 9. TheV driven verti cal arbor projects downwardly beyond the closure-plate and has secured thereon. in a pendent position by a set-screw a couplingsleeve 10, having its upper end adapted to receive the arbor and prevent lubricating-oil escaping therefrom into the churn, andat its lower end is provided with an angular socket adapted to receive the angular paddle-arbor l1, to which the paddles 15 are secured in helicoidal relation. `The foot of the paddle arborll is stepped in a socket 12, formed by a depression integral with the bottom of the crock, and is in vertical alinement with the receiving-socket secured to the arbor '7. By this construction the closure t, with the op erating mechanism secured thereto, together with coupling-sleeve 10, may be removed from the churn Vessel separate from the paddle-arbor 11, and after removing closure 4 sleevelO may be removed from arbor 7 and loo separately cleaned of anyoil or the like vac-V cumulated therein. By the use of sleeve as.

Projecting inwardlyfrom the wall of vessel 1 Y and integral therewith are breakers 13, which operate to break up the centrifugal currents `produced -by the revolving paddles. These breakers are tapered at their lower endsto their connection With the wall to allow the bottom paddle 15, whichY is provided with a lip 14, adapted'for the purpose, to reach into the angle formed by the Wall and the bottom,

whereby the cream that ordinarily remains vundisturbed therein, as Well as the main body of it, is evenly agitated when the paddle-arbor is revolved.- By the spiral arrangement of the paddles a constant upward current is produced, which assists in gathering. the butas they are formed at the top of the iluid. v 4 i The top closure is secured to the churncrock by means of bolts 16, having integral `therewith elongated heads 17, projecting in opposite direction from the body p0rtion18 and are adapted to enter the groove formed upon the vunder side of the enlarged rim.

19 designates notches formed upon the periphery of the rim, adapted to receive the vertical stem of the bolts,which project upwardly above the rim through plates 20, provided 2 f A`cargoes@ With orifices toreceive the bolts.. The plates 2O are suitably secured to the top closure and the bolts tightened by means of thumb-nuts y21, and by means thereof the closure is drawn against the ledge 22, concentric with the rim and formed thereby..

VWhat I claim is- The butter-churn herein described, comprising an earthenware vessel having its top edge provided with an interior annular ledge 22, for receiving and supportinga cover for the vessel, and thebottom with socket 12, and having formed integral therewith vertical breakers 13, and a concentric exterior rim'2, provided with a concentric groove 3 on its under side, and vertical notches 19 in its periphery; a top closure 4, having projecting plates 20, provided with bolts 16, having heads 17, and thumb-nuts 2l; a shaft 7 mounted on the cover 4, and extending centrally through it, Aprovided with gear mechanism adapted to rotate it; a coupling-sleeve lO, and a paddlearbor 11,p`rovided with paddles; all constructed, combined and operating as shown and described. j

In testimony that I claim the foregoing as my own l hereby aiIix my signature in the presence of two witnesses. V
