CHURN.

SPECIFICATION forming part of Letters Patent No. 308,869, dated December 9, 1884.

I Application filed February 27, 1883. (N0 model.)

To all whom, it may concern.-

Be it known that I, ANDREW J. BORLAND, a citizen of the United States, residing at Donnellson, in the county of Lee and State of Iowa, have invented certain new and useful Improvements in Ghurns; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as 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 letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the churn for which Beissued Letters Patent No. 9,338 were granted to me August 10,1880; and the invention consists of the combination as hereinafter described and claimed.

In the accompanying drawings,which illustrate my invention, Figure 1 is a vertical sectional elevation in line 00 a: in Fig. 2. Fig. 2 is a top plan of the churn-barrel, and section of the dasher-shafts and standards in line xx in Fig. 1. Fig. 3 is a side elevation of the churn-barrel and supportingstool. Fig. 4. is a sectional elevation of the lower ends of the dashershafts and bottom of churn -barrel. Fig. 5 is a perspective of the supporting-stool. Fig. 6 is a section in the lid at one side of one of the fastening-eyes.

Referring to the drawings by letters, the same letter indicating the same partin the different figures, A represents a churn-barrel elliptical in its cross-section and formed of stavcs a, same as shown in my patent hereinbefore referred to, except that the staves at their upper ends are united by dowel-pins a, which serve to hold the staves from the displacement to which they are peculiarly liable in an elliptical bar rel. The top of the churn-barrel is formed in The part B preferably has no removed. The part B is held in place by hooks b on the barrel,which engage with eyes I) on the part B. The eyes I) have elongated ends b,with eyes 7/, through which a screw, 0, passes to hold it in place, and for further security the other end, 12, of the wire which forms the eye b is inserted iii the outer edge of the part B, as shown at Fig. 6, which is a section through part of the lid B at one side of an eye, b. The eyes bpass down into slots 0 in the upper part of the barrel A, and the hooks b are then engaged with them and hold the part B from rising, while the slots 0 secure it from moving otherwise,and thus make of the part B a firm base for the standards F, which carry the driving mechanism, and at the same time a base which can be removed, to remove the dasher-shafts, or for other purposes.

E Eare the dasher-shafts, journaled on pintles e at their lower ends. The pintles e are formed of wood, and are supported in thebottom of the churn-barrel by short pins or studs 6, resting in slots 0r countersinks e, as shown at Fig. 4. Each shaft E is provided with a collar or annular ring, 6, immediately below whereit passes through partsBB,which rings a serve to prevent the 'milk being splashed out at the opening in the lid, around the shafts E.

F F are standards secured to the part B, and their upper ends bentinward and toward each other, and provided with bearings for a shaft, G, which carries miter-wheels H H, at ashort distance from each other, and is provided at its outer end with a crank, g.

I is a bar connecting the standards F below the miter-wheels H.

J J are miter-wheels, the shafts j of which have bearings in the bar I and standards F. A wheel, J, gears with each wheel H on the outer sides of the wheels H, so that the wheels J will retain the shaft G from endwise movement. This is accomplished by curving the arms F over wheels J, so that the wheels H will be in the space between wheels J The lower ends, j, of the shafts j extend downward through thebar I, and are square in their crosssection, and enter square sockets in the upper ends of the shafts E, so that the shafts E will be rotated in opposite directions by the wheels J as they are rotated simultaneously by the wheels H, which are operated by the shaft G and its crank g. The dasher-blades K are perforated in the ordinary manner, and in addition thereto have their central parts removed in a triangular recess, 70, as shown at Fig. 1, whereby their passage through the milk is facilitated and the resistance of the milk to all parts of the blade is equalized by the blade having less surface as it approaches its outer end, where its velocity over an equal distance is greater than at its inner end.

L is a supporting-stool, formed of legs Z, united by rounds Z a short distance from the tops of the legs Z,' and by rounds Z, each of Which connects a pair of the legs Z. The rounds Z are connected at their central parts by a stretcher, Z. By thus connecting the rounds Z a pail may be inserted between two of the legs to receive the buttermilk from a' scupper, m. The upper projecting ends, Z, of the legs Z form guards to retain the churn-barrel on the rounds Z.
