SPCFICATION forming part of Letters Patent No. 433,503, dated August 5, 1890.

Application filed Jannary29, 1890. i Serial No. 338,502. (No model.)

.To all whom it may conccrn:

Beit known that I, J AY F. XVILSEY, a citizen of the United States, residing at Jerry City, in the county of WVood land State of Ohio, have invented certain new and nseful Improvements in 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 it appertains 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 churns of that character in which a series of revoluble dashers are caused to agitate the material to be churned.

The object of my invention is to provide a series of paddles or dashers set obliquely to radial planes passing through the shaft, with the inclination of each dasher directed from the outer end of the churn toward the center, whereby to not only agitate the cream circumferentially of the axis of the dashers, but longitudinally of the churn.

A further object is to introduce a current of atmospheric air into the churn in such relation to the axis of the dashers that they (the dashers) by their obliquty to the axis and point of ingress of the air will draw the same into the churn and force the air into the cream.

A further object is to cause the airto enter at the desired points of ingress and escape by a separate and distinct point of egress.

A further object is to journal the shaft upon which the dashers are secured in a manner to allow of easy removal of the same.

A further object is to so construct the airingress ports that they may be provided with a removable foraminous covering, thereby preventing the ingress of dust or dirt particles incident to the draft of air through the ports caused by the Vacuum created by the obliquely-moving dashers.

The invention consists in the parts and combination of parts hereinafter described, and pointed out in the claim In the drawings, Figure 1 is a side elevaM tion of a churn, showing the gearing for actuating the dashers in edge view. FigB 2 is a longitudinal vertical sectional view through secured the metal U-shaped body portion B,

preferably by forming a correspondinglyshaped groove O in the end pieces and letting the ends of the body B therein, and drawng the end sections closely against the ends of the body by means of rods D, extending longitudinally of the churn, the edges of the sides being bent around the upper rods, as shown in Fig. 8. The receptacle is mountecl upon legs F, secured to the end pieces and closed by a removable cover G, formed with an airescape pipe H.

In each end piece A of the churn-body there is formed a vertical air-duot I, leading from the top down to near the middle portion of the end piece. Communicating with this vertical air-duot near the top is an outer lateral Opening J for admitting air from the outside, which ope'ning is guarded against the ingress of dust, &c., by a removable foraminous covering K, held in place by being se cured to a frame which slides in ways K' attached to the end piece A, and at the bottom of the air-duot I there is an inner lateral Opening J' on a line with the upper surface of the dasher-shaft.

L designates the dasher-shaft, the body of which is formed of wood, upon each end of which is secured metal thi mbles, one of which L' is formed with a rectangular perforation in the end to receive the Square end of a journal M, having a bearing in end piece A, upon which there is secured a pinion M' which meshes with a gear-wheel N, journaled in the upper portion of the churn, and provided with a cran-k N'. The opposite end has a thimble L secured theren, which has a semicircular'recess into which is centered a bearing O, screw-threaded to run into a nut O' set into head A' the end of the bearing O being provided with a thumb-hold by which to set the same to any desired adjustment-flas a pivotal bearing-fl-and being held to the ad- IOG jnstment by means' of a nut P, run upon the i same, and which bears upon the nut O' frictionally to prevent the bearing from unscrewing.

P' designates pins passed through shaft L at diametrically-opposite points, upon which are Secured the dashers Q, one upon each end, the dashers being inclined oppositely and at oblique angles to a radial plane passing through the shaft, Whereby in the revolution of the shaft the outer ends of the dashers-- e. those ends`nearest the ends of the churn-have an inclination toward the center of the churn, thus causing the cream to be moved circnmferentially of the axial plane of the shaft, and-also longitndinally of -the,same, .thereby by: pressure divesting the butterglobu1es of the membrane that .iincases them as the cream is nrged to :the center by theobliquity of .the dashers-an-effeot far Superior tothat caused by directimpact of thedashers.

An important: result attained by locating the. air-inlets .v J on :a line-With the dashershaft and having one of .these inlets at beach sideis that,-owing to the vacunm in .the vicin ity of these inletsv caused by the revolution of thevdashers; a constant-cnrrent of air is drawn into thev churn froin each side, meeting in the middle. along the line-of the shaft','fron1 which position,-.as the fiuid is urged toward the center, it -isthoroughly.distributed an d incorporated into the cream-,,thereby, on awelLknoWn principle, causing the butter-globules to readily separate from the cream, and also serving to carryoif` the impurities of the latter.

In order to provide means for cleansing the air-ducts, the openings extend through the Upper. ends of the end sections, as shown, Whereby When :the cover G and the forami-` nous coverings K are removed Water may be poured into the vertical passages Lwhich, findi ing its. egress into the churn, removesany butyric particles that may have been forced therein.

In order to remove the dasher-shaft, the nut P is run back, thereby allowing the journalbear-ing O to beunscrewed from contact With the bearing' in thimble L' when by inclining the shaft it can be withdrawn from the churn.

It will be understood from the for-egoing de4 scription that by the agitation of the cream longitndinally in opposite directions, and also spirally, due to the obliquity of the dashers, thewhole mass of cream is agitated evenly, thereby convertin g the maximum amount into butter of a finer -texture thaniwhen theope-r- -ation is eifected by direct impact, and that by reasonof the obliquity-of the dashers and the relativepoint of ingress of air'thereis-in- So sureda const-ant currentofv air in =incorporation `With the cream.

-WVhat I claim is-- Ina ehurn having a ho'rizontal-da'sher-.shaft journaled therein, endse'ction of' thechurnvbody having vertical :air-ductsr; leading from the top-downward toward theshaft, lateral air-pass'ages. leading' from the outer side of the churn to said'dncts and lateral. air-passages leading from the bottom-of- `the ducts yo to the inner side of. the:chnrn,.and.a churncover closing .the upper ends of the'airkducts and having an air-vent, for the purposesset forth.

' In testimony that I claim the rforegoing as myown I .herebyafx my Signature in. pres4 enceof two Witnesses.
