CHURN.

SPECIFICATION forming part of Letters Patent No. 427,188, dated May 6, 1890.

Application filed A t 23, 1889. $erial No. 321,743. (No model.)

To all whom it may concern.-

Be it known that we, JOHN H. REBOK, THOMAS T. lVlAGUIRE, and PHILIP K. REBOK, citizens of the United States, residing at T0- ledo, in the county of Tama and State of Iowa, have invented a new and useful Churn, of which the following is a specification.

This invention has relation to that class of churns known as reciprocating dashers, and although herein shown and described for the churning of butter the same may be employed with equally good results for beating large quantities of eggs.

Among the objects of the invention are to effectually cut and separate the globules of cream and regulate the temperature of the contents of the churn by means of the introduction of cold or warm air for the purpose of quickly reducing or raising the temperature, as may be desired, during the operation of churning, and for the purpose of securing the well-known advantageous results; to provide for the ready introduction of cold or warm air at each upstroke of the piston, and to diffuse such air equally throughout the 0011- tents of the churn; to provide a convenient motor and means for securing the same in a removable position over the churn, and to con struct the dasher-disks so that a thorough separation of the globules shall take place.

lVith these general objects in view the invention consists -in certain features of construction, hereinafter specified, and particularly pointed out in the claim.

Referring to the drawings, Figure 1 is a .perspective of a churn constructed in accordance with our invention; Fig. 2, a central vertical section of the same, the motor removed; Fig. 3, a detail in perspective of the dashershaft and its disks. Fig. 4: is a bottom perspective of the churn-body detached.

Like numerals of-reference indicate like parts in all the figures of the drawings.

1 represents a floor or base, from which rise at triangular points standards 2, the lower ends of which are bolted to the floor or base, and the upper ends of which support a churnsupporting ring 3. Mounted in the ring is the churn-casting 4, preferably cylindrical or barrel shaped, and provided upon the upper surface of its bottom with upwardly-projecting studs 5.

6 represents the churn proper of cylindrical shape, and of a diameter considerably less than the casing, the bottom of the churn being upwardly convexed or conical, as at 7, and provided at its base with depending legs 8, terminals of which are concaved, as at 9, to form sockets for the reception of the studs in the bottom of the casing.

10 represents a removable cap for the churnbody, provided at its center with a flared opening ll,the cap being preferably threaded and screwed into position upon the churn-body.

12 represents the dasher-rod, which projects through the flared opening in the cap,

and is provided at its lower end with a conical disk 14:, having a dome or apex 15, and perforated and radial slots 16, formed in its conical wall. Above the dome and upon the rod 13 is mounted a second disk 17, slightly smaller than the first-mentioned disk, also of a cone shape and provided with a series of perforations 18. v

The apex of the bottom of the churn-body is provided with an upwardly-projecting valve-chamber 19, having a valve 20, and an opening 21 in the upperend of the chamber,

over which is a strainer 22. A pipe 23, suit ably packed, leads from the lower end of the valve-chamber and up to within a short distance of the top of the churn-body, where by a coupling 24 the same. is connected with a flexible pipe-section 25, the opposite end of the section being adapted for connection with any suitable cold or hot air reservoir.

Any means may be provided for operating the churn-dasher,but we will herein describe a form of construction which we consider best adapted for the purpose. 26 represents a rectangular frame, one end of which is hinged to the casing at its upper edge, as at 27, the frame extending across and resting upon the opposite edge of the casing and having its side bars 28 upwardly offset, as at 29, so that the corners 30, formed by the offset, form the four points of contact with the cap or cover of the churn-body and serve to aid in retaining the churn in position. From the front end of the frame there depends a hasp 31,

which takes over a staple 32, projecting from the exterior of the casing, through which a locking-pin may be inserted and the frame bound tightly upon the churn-body. 33 represents an inverted-U-shaped gear-supporting standard, the lower ends of which are bolted, as at 34, to the opposite offsets of the side bars of the frame and are connected by a transverse bar 35, having a central opening 36 directly over the central opening in the cap of the churn-body. Above the transverse bar and within the U-shaped standard is journaled a crank-shaft 39, from the crank portion of which depends a pitman 40, connected by a pin 41 with the dasher of the churn. A small gear 42 is fixedly mounted at one end of the crank-shaft and meshes with a master-gear 43, mounted upon a stub-shaft 45, journaled in one of the branches of the U-standard and provided with an operating-crank 44. The churn-body is surrounded by a suitable packing of temperature raising or lowering agents, as desired, and the master-gear revolves, which reciprocates vertically the dasher-rod or shaft and its pair of conical-shaped dasher-disks. The contents of the churn is caught by the downwardly-moving disk and forced by the same upon the conical bottom, and around the sides of the disk and through the radial openings therein, and then in contact with the second and more finely-perforated disk, where the separation of the cream globules is completed. At each upstroke of the dasher the valve in the conical bottom is open, and cold or warm air, in accordance with the necessities of the operation,is drawn in by suction and forced through the body of cream at the down- 1 stroke, at the beginning of which the valve is closed, and in this manner high and low temperatures for accelerating the converting of the cream to butter are quickly secured. The constant forcing of air through the cream also has a tendency to agitate the same.

Having described our invention, what we claim is The combination, with the churn-casing, of the churn-body mounted in the casing and supporting-feet for elevating the body above the bottom of the casing, said body being provided with a conical bottom terminating at its apex in a superimposed valve-chamber provided with upper and lower openings, the lower one forming a valve-seat and provided with aball-valve, an air-pipe leading from the lower opening and up between the casing and churn, and provided with a flexible pipe adapted for connection with a warm or cold air supply, a reciprocating dasher mounted in the churn-body, and having a perforated disk at its lower end adapted to fit the bottom of the body, and having a hollow dome to receive and close over the valve-chamber, and a second perforated disk mounted upon the dasher above the lower disk, substantially as specified.

In testimony that We claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
