SEECIFICATION forming part of Letters Patent No. 524,122, dated August '7; 1894.

Application filed April 19, 1894;. Serial No. 508,149. (No model.) y

To a/ZZ whom it mayconoern:

Be it known that I, ROBERT E. VAN COURT, a citizen of the United States, residing at Elkton, in the county of Rockingham and State of Virginia, have invented certain new and useful Improvements'in Ohurns, of which thev following is a specification, reference being had therein to the accompanying drawings, in Whichet..

Figure lis a transverse sectional View of my improved churn; Fig. 2 a plan View thereof, the cover being removed; Fig. 3 a longitudinal sectional View; Fig. 4 a detail of the adjustable breaker; and Fig. 5 a diagram showing the action of the beaters and the cu rrents of cream caused by them.

The invention relates to a new and im-v proved churn, and it has Vfor its object to provide a device of simple construction which will greatly agitate the cream and produce butter therefrom very quickly.

The invention consists in the novel construction of the beaters, and their arrangement on the revoluble shaft; the construction and arrangement of the breaker or .de flector which is located on the side of the churn; and certain other novel features of construction and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the claims appended. v y

Referring tothe various parts by numerals,

1 designates the box or body of the churn; 2'

the cover therefor, said cover being hinged to the churn body and rabbeted to iit down over the upper'edge of the box, an air hole and a peep-hole being also formed in the cover; 3 a bracket secured to the side of the churn-body in a position to support` the cover in a horizontal position when the churn isl open; 4 the horizontal dasher-shaft journaled transversely of the churn body, one of its i ends being journaled upon an adjustable trunnion'5,its other end being provided with a rigid journal which projects Vthrough the churn-body and is provided on its outer end.

with a gear Wheel 6; 7 the beater arms which are secured to the shaft 4c, and are located equal distances apart on the same, said arms being staggered or set out of line around the shaft, as shown; 8 the beaters or agitators have a peculiar formation, and are designed to produce certain currents in the cream.

These beaters are each formed with one inner straight side 9 and one'outer curved side 10, which sides converge and meet in a sharp point 1l at the frontend of the beater. The straight side lO extends rearward slightly beyond the point of attachment'of theI beater to the beater arm 7 and from the rear end of this straight side a curved side 12extends rearwardly and outward ly,and from the rear end of this side 12 a short straight side 13 eX- tends outwardly and slightly for\vard,its forward end meeting the rear end of the curved outer side 10 as shown clearly in the drawings. p

The beaters or agitators carried by the central arms 7 are of a different form from those carried by the outer arms, and are each formed with a blunt .or curved forward end verted and divided by meeting the outer beaters 8 which beaters by reason of their straight inner sides cause part of the current to iiow inwardly toward the centerof the churn and in the path of the next central beater, and by reason' oftheir'curved outer sides cause part fand two diverging, rearwardly-extending of the current to be dashed against the sides j of the churn. The next central beateragain divides the current and the above described movement of the cream is repeated as the dasherfshaft is revolved, thereby producing ,a1 great agitation of the cream, as is manifest. As the beaters are revolved the'cream is lifted toward the rear side of the machineand in order to prevent it rising to the cover I provide a breaker or deflector which Vis secured to the rear side of the churn and deflects or returns the cream into the churn. This deiiector consists of the flexible strip 17 bent into U-shape and secured between two rigid blocks -18 by means of a removable block 19. A removable pin 2O is inserted in the churn side directly above the block 19 to prevent the withdrawal of the block. The adjacent edges of the blocks 18 and the removable block 19 are beveled inwardly and downwardly to A receive the diverging upper ends of the strip 17. As will be readily understood theblock 19 may be readily removed by removing the pin 20, and the strip 17 may then be adjusted up or down according to the amount of cream in the churn. As will be readily understood the rising of the cream will be arrested andthe cream returned to the churn by the st1ip`17 and theblocks 18, the curved lower end of the strip 17 dividing the current and breaking its upward tendency and aiding materially in agitating the cream. The blocks 18 also act as a stop and will break the upward movement of the cream if the curved piece 17 does not. The strip 17 and block 19 may be readily removed for cleaning when desired.

When the butter lhas formed and it is desired to gather it it is simply necessary to reverse the direction of the movement of the dasher shaft, and the curved rear sides 12 of the beaters will gather the butter to the center of the machine.

Any suitable means for revolving the dashershaft may be employed, but l have shown a Crear 22 rovided with an o eratinof s P P s v hand-le and journaled on the side of the churn body and meshing with the gear 6 of the dasher-shaft.

The under side of the cover is concaved to form a butter bowl or tray, as shown in Fig. 1 of the drawings, and when the cover is open and resting upon bracket 3 the butter may be worked and printed in said concaved portion, as is manifest.

Having thus fully described my invention, what I claim is 1. A churn consisting of a churn body, a dasher shaft journaled therein, beater arms carried by said shaft and staggered thereon, beaters being arranged in an inner and two outer series, the inner series being formed with the outwardly curved forward end and the diverging sides, andthe two outer series being formed with the straight inner sides, the curved outer sides and the curved rear sides, substantially as described .and for vthe purpose set forth. v

2. A churn consisting of a churn body, a horizontal dasher shaft journaled therein, beaters carried by said shaft, and a breaker or deflector, said delector consisting of the iiexible U-shaped strip and means for adjustably supporting it in position, substantially as described.

3. A churn consisting of a casing, a horizontal dasher-shaf t j ournaled therein', beaters carried by said shaft, said beaters being arranged to form. an inner series and two outer sets or series, one on each side of the inner series, the inner series dividing the cream and throwing it outwardly from its sides, and the two outer series th rowing it inwardly into the path of the inner series and outwardly against the sides of the churn, and an adjustable breaker .or deflector secured to the end of the churn in the path of the ascending currents of cream, substantially as described.

4. A churn consistingof a churn-body a horizontal dasher-shaft journaled therein, beaters carried by said shaft and an adjustable breaker or defiector secured to the end of the churn in the path of the ascending currents of cream, said breaker consisting of the flexible U-shaped strip, stationary blocks 18, removable block 19, and the removable pin 20, substantially as described and for the purpose set forth.

In testimony whereof I afliX my signature in presence of two witnesses.
