CHURN.

SPECIFICATION forming part of Letters Patent No. 771,937, dated October 11, 1904. Application filed November 12, 1903. Serial No. 180,962. (No model.)

T0 61/ whom it may concern:

Be it known that I, SALLY RooK, a citizen of the United States,residing at Morrisonville, town of Schuyler Falls, in the county of Clinton and State of New York,have invented new and useful Improvements in Churns, of which the following is a specification;

This invention relates to churns of that class having a rotary dasher and foot operating means therefor, and it will be understood that an ordinary crank-handle may be substituted for said operating means.

This improved churn is of simple and effective construction and embodies means whereby the butter as formed is thrown over from one part of the churn into another and retained in a butter-receiving compartment in mass when the buttermilk is drained off from the churn-body at the conclusion of the churning operation.

The improved churn also includes in its structure a chamber partially surrounding the churn-body to receive either a refrigerating material or heating liquid or substances to regulate the temperature of the cream for churning.

In the drawings, Figure 1 is a perspective View of the churn embodying therfeatures of the invention. Fig. 2 is atop plan view of the same with the lid or cover removed. Fig. 3 isia central longitudinal vertical section; and Fig. is a transverse vertical section on the line 4 4:, Fig. 3.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates the churn-body, having supporting-legs 2 of suitable length and a removable lid or cover 3, provided with a handle or grip 4L. Arranged within the body of the churn at one side of the center is arotary dasher 5, having arms arranged at an angle to each other and provided with terminal beaters 6. The shaft 7 is reduced at the opposite ends, which project through the sides of the body 1 and have secured thereon cranks 8, to which are movably attached the upper extremities of pitmen 9, also movably connected at their lower ends to the inner extremity of a treadle 10, having a fulcrum-bar 11 at its outer end, with reduced terminals rotatably held in bearings 12, secured to the inner edges of one pair of legs. The footboard 13 of the treadle is readily accessible from one end of the churn, and it will be understood that the dasher 5 may be readily rotated by oscillating the treadles 10, as in the usual manner of operating such devices. Instead of the treadle and its connections as set forth the dasher may be operated by a crankhandle.

The interior of the churn-body 1 is divided into two compartments 14 and 15 by a removable partition 16, vertically slidable in opposite guides 17, the said partition being materially of less vertical extent than the depth of the body 1. The lower part of the partition is formed with an opening 18, having a reticulated or wire-gauze cover 19 of suitable mesh, and the upper edge of said partition is provided with a projecting grip-rail 20 for convenience in removing and applying the partition. The ends of said grip-rail have close contact'with adjacent surface portions of the guides 17 when the partition 16 is in place, and thus are the sides of the body structure braced from within, as is apparent. The bottom of the body 1 is transversely constricted by inclining the lower portions of the side walls inwardly, as at 21, to facilitate a more reliable drain or outlet of the buttermilk after the churning operation is completed through an opening 22 normally closed by a plug 23. The guides 17 and the partition 16 have their lower portions shaped to conform to the lower part of the body 1, as clearly shown by Fig. 4:, and when the partition is in its lowest position the lower edge thereof is in contact with the bottom of the body 1.

The churn as thus far described can be used without any additional features of construction, and in the operation of the same the cream to be drained is poured intothe compartment 14 and runs through the opening 18 into the compartment 15. The dasher is set in motion as in the ordinary churning operation, and as the butter is formed and comes to the top of the cream it will be thrown by the dasher over the upper edge of the partition 16 into the compartment 15, the beaters 6 acting as gatherers and facilitating this butter-fornning operation. When the churning operation is completed and all the butter has been properly gathered and thrown into the compartment 15, the plug 23 is removed and the buttermilk flows out of the churn-body, leaving the butter in a mass within the compartment 15, from where it may be readily taken and treated as in the ordinary methods of butter-making.

An advantageous addition is shown in connection with the churn and consists of a chamber 24 surrounding a portion of one end and extending below and fully covering the bottom of the body 1, the vertical portion of said chamber having unobstructed communication with the horizontal part thereof. The vertical part of the chamber is covered at its upper end by a hinged lid 25 and facilitates draining such chamber of-its contents, and an opening is formed near the bottom of the chamber and firmly closed by a plug 26. The chamber 24 is adapted to receive warm water for properly tempering the cream when the latter is cold or chopped ice to also regulate the temperature of the cream when it is too warm, and thereby facilitate the formation of the butter and expedite the churning operation, as will be readily understood.

The churn can be readily cleaned and the interior of the body 1 thereof made readily accessible at all points by withdrawing the partition 16, and in similar instances the dasher may also be removed, as will bereadily understood in the art of churning.

Changes in the proportions and dimensions may be made without departing from the spirit of the invention.

I claim- A churn having a body with guides arranged on the inner opposing sides thereof, avertically-disposed transversely-arranged slidable partition engaging the guides and dividing the body into two compartments, the said partition being freely removable and lessinheight than the height of the said body and provided with a lower screen-covered opening and an upper grip-rail, and a rotary dasher in one of the compartments provided with radial arms having heaters at their outer ends.

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