SPECIFICATION formingpart of Letters Patent N o. 727,032, dated May 5, 19'03.

Application filed August 16, 1902.

To ctZZ whom, it may concern,.-

Be it known that I, NELSON J. TUBBS, a citizen of the United States, and a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Churns, of which the following is a specification.

The primary object of this invention is to provide a churn which shall be simple in construction and effective in operation and in which the operating mechanism for the churndasher and the supporting-legs for the churnbody can be readily and conveniently taken apart and stowedV within the churn-body for convenience in shipping the churn and to reduce the .apparatus-to a compact form for storage.

With the above objects in view the invention consists in the particular construction and arrangement of parts and their combination, all as will be hereinafter fully described in the following speciication and more specifically set forth in the appended claims.

In the drawings which form a part of this specification, Figure l is a vertical sectional view of a churn constructed in accordance with my invention. Fig. 2 is a sectional view showing the connection between the dasherrod and the supporting-frame for the operating mechanism. Fig. 3 is a detail view of the lower dasher. Fig. 4 is a detail view of the supporting-bracket for the standard.

Referring to said drawings, A designates the churn'- body, which is preferably cylindrical in shape and is constructed of wood in order that the fixtures hereinafter described may be secured thereto by ordinary woodscrews; but, if desired, the said churn-body may be made ofmetal and the fixtures riveted thereto. This churn-body is supported directly upon short'legs B, the upper ends of said legs tting into sockets b, secured to the lower end of the churn-body, and the socketopenings are disposed at an angle, so that the supporting-legs will spread, as shown. By providing the sockets and connecting the supporting-legs directly thereto the said legs may be readily removed and stored within the churn-body.

Secured upon one side of the churn-body serial No. 119,943. (No noaa.)

A, near the upper end thereof, is a casting C, provided with a vertical opening which is adapted to' receive the lower end of the standard D of the frame which supports the operating mechanism of the churn. The said casting is provided with a set-screw c, so that the supporting-frame can be readily adjusted to any desiredl height and securely held. The supporting-'frame consists of the standard D, a horizontal arm d, and vertical members d d2, extending upwardly from said arm at the ported bythe frame in the manner hereinafter described.

Mounted upon the shaft E and bearing against the outer side of the shaft-bearing d' is a large bevel gear-wheel F, inl mesh with a pinion I on the hollow dasher-rod L, which is adapted to revolve within the churn-body and carries the dashers hereinafter particularly described. The upper end of the dasherrod is supported in a socket M, having a bifurcated upper end, which receives a fiat projection n 011 a sleeve N, loosely mountedon the inner end of the driving-shaft E, the said sleeve bearing at one end againstrv the gear- Wheel F and at the other end againstawasher o, held on the shaft by a Cotter-pin o'.' It'will be here noted that the flat portion n does not project from the center of the collar N, but is located nearer onez end `thereof than the other, this being provided for to locate the socket M at different distances from the gearwheel F, so that different-size piuions may be mounted on the dasher-rod to mesh with said gear-wheel. To this end the said pinion I is removably mounted on the dasher-rod, being secured thereon by a set-screw fi. It

will also be noted that the socket M is pivotally connected to the projection n of the A l 4 I.'

sleeve N by the Cotter-pin m, which passes' ,through them, and that this provides a Vyielding joint that will obviate any strain yon the parts. V

The hollow dasher-rod is threaded at its lower end to receive the dasher P, which is screwed thereon, the said dasher being provided centrally with a conical bearing'p, which is stepped in a hard-wood socket Q, located in the center of the bottom of the churn. This socket Q is driven in a hole formed in the center of the bottom of the churn and when Worn can be readily replaced byanother. ThedasherPconsistsofasquare plate having centrally a threaded hub 1f, by which it is screwed upon the lower end of the dasher-rod, the lower end of said hub forming the conical bearing hereinbefore referred to. Extending across the under side of the plate or dasher P from the lower end of the hub p' are hollow ribs p2, the dasherrod terminating above said ribs, so that air may pass from said dasher-rod into said ribs, the latter opening out at the outer end of the plate or dasher, so that when the dasher is revolved rapidly the air will be drawn down4 the dasher-rod and discharged from the hollow ribs by centrifugal force. The dasherP is provided on its upper side with a number of vertically-projecting paddles p3 of difterent lengths and disposed irregularly, as shown, the short paddles at the inner part of the dasher being formed integral with the hub p'. The particular arrangement of the paddles on the upper side of the plate and the arrangement of the hollow ribs of the under side thereof provides a suction which will draw the air down the hollow dasher-rod and discharge it into the body of milk or. cream, so as to thoroughly aerate the same, the air entering the upper end of the dasherrod through the opening at the upper end of the socket M.

Above the dasher P is located a dasher R, having inclined blades projecting from a hub, and in order that a dasher of this character may be made more effective in operation I provide the blades with openings fr. These openings serve to form additional currents,

and consequently agitato the cream to a greater extent than a solid blade.'

At opposite sides of the body of the churn are arranged vertical plates or breakers S, the lower ends of which are provided with points or pins s, which enter the bottom of the churn, while the upper ends are provided with holes which register with holes in the sides of the churn and receive cotter-pins s', by which the said breakers are held in place. The inner edge of these breakers are cut away, as shown, to form a vertical opening adjoining the sides of the churn.

The operation of the churn will be readily understood, and in practical use I have found that a revolving dasher-rod provided with dashers constructed as herein shown and described produces a churn in which the churning of the milk and cream is greatly facilitated. The changeable gear is provided so that a more rapid motion maybe imparted to the dasher-rod in churning sweet cream and milk, while a slower speed may be provided for in churning sour cream 'and milk, it being understood that one required afaster motion than the other.

By constructing the different parts of the churn as herein shown and described the legs can be removed and placed in the churnbody and the parts of the operating mechanism all separated and placed in the churnbody also. It will also be observed that the churn-body or barrel is firmly supported at the required height and that the frame which supports the driving mechanism is connected to the upper part ot' the barrel, whereby the construction of the churn is considerably cheapened. Y

Having thus described my invention, I claiml. In a churn, the combination with the barrel and vertical dasher-rod,of a socket secured to the upper end of the barrel, a frame having a standard secured in said socket and providing bearings for a horizontal shaft, a gear- Wheel on the inner end of said shaft in mesh with a pinion on the dasher-rod, a sleeve on the shaft having a depending fiat portion, and a socket having a bifurcated upper end pivotally connected to the projecting portion of the sleeve, substantially as shown and described.

2. In a churn, the combination with the barrel and dasher-rod, of a horizontal drivingshaft supported in a suitable frame and carrying a gear-wheel in mesh with a pinion on the dasherrod, a sleeve on the end of the drive-shaft having a projecting portion, and a socket pivotally connected to said depending portion of the sleeve, the said socket receiving the upper end ofthe dasher-rod, substantially as shown and described.

3. In a churn,the combination with the barrel and flasher-rod, of a supporting-frame providing vertical bearings, a drive-shaft mounted in said bearings, a crank-handle adjustably secured to the shaft on one side of a bearing, and a collar adjustably secured to the shaft on the other side of said bearing; together with a sleeve having a projecting portion nearer one end thanv the other, a socket pivotally connected to said projecting portion, a removable pinion on the dasherrod, and a gear-wheel on the drive-shaft adapted to mesh with the pinion, substantially as shown and for the purpose set forth.

4. In a churn, the combination with the barrel and dasher-rod, of sockets secured to the lower end of the barrel and to one side of the upper end thereof, supporting-legs adapted to engage the lower sockets, and a supporting-frame for the driving mechanism removably connected'to the upper socket; together with the drive-shaft supported in the frame, a sleeve on the inner end of the shaft, and a ICC IIC

socket pivotally connected to said sleeve, the said socket receiving the upper end of the dasher-rod, substantially as shown and described.

5. Ina churn, the combination with the barrel and hollow dasher-rod, of a dasher mounted on the lower end of the dasher-rod and consisting of a plate having a hollow hub in which the dasher-rod is stepped, a series of vertical plates or paddles arranged around the hub, a series of vertical plates or paddles at the outer ends of the plate, and an intermediate series of vertical plates or paddles, the latter being disposed out of line with the others to leave spaces between the said plates or paddles; together with hollow ribs or tubes extending across the under side of the plate from the hollow hub.

6. In a churn, the combination with the hollow dasher-rod of a dasherconsisting of a across the under side of the plate, said ribs communicating with the hollow dasher-rod, substantially as shown and described.

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