Letters Patent No. 86,094, dated Janna/ry 19, 1869.

IMPROVEMENT IN CHURNS.-

The Schedule referred to in these Letters Patent ai making of the eamo.

-of reference marked thereon, of which drawings- Figure l is an end elevation of our improved churn. Figure 2 is a plan of the same. Figure 3 is a plan of a dasher and shaft.

Figure 4 are side and front elevations of the same.

Figure 5 are elevations of the two sides of thefoper ating-wheel.

Figure is a sectional view, showing mode of secur ing the churn-cover and dasher-shaft.`

The nature of our invention consists in a novel mode of operating two upright dashers, in a common upright churn, whereby we obtain arrapid reciprocating and alternative movement of the dashers, and produce a violent agitation of the cream, and thus effect a rapid churning of the butter, the whole machine being` so arranged as to be of simple and cheap construction,

not liable to get out of repair, and easy to take apart and clean, all of which are essential features to a perfeet churn.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

The frame of the machine is composed of four principal uprights, A A- and B B, which are united by sideframe pieces F F and E E, and cross-pieces G Y.

The rear uprights B B extend below the-lower sidepieces` E E, and form two of .the feet of the machine, the feet X X, under the-other ends of these side-pieces, forming the other feet.

The upper ends of the front uprights A A are formed as shown, and pass through holes in the sliding crosspiece H.

A board, D, is attached to the lower side of the lower side-pieces E E, directly i'lnder the uprights A A, and on this board is placed the churn R, which is secured in positionv by boards C G, which are cut out,

, to fit up to the churn, and are secured to the side-pieces E E, as shown, or the churn can be secured in any other suitable manner.

The churn It is of an ordinary form, and may be constructed of any suitable material.

Around the inside of the churn, and-a little below the top edge of the same, is secured the riin g, which is of considerable width, and serves as a support tothe covers h h, as well as to prevent the cream from slopping up and overv the sides of the churn.

The covers h h` are of a semicircular form, and iit together on the rim g of the churn, as shown, where they are secured by a bar, S, which is held down by a screw, Q, with nut b, bearing under the cross-piece Y, said screw passing up through the piece Y, and being operated by the head a at its top.

The dashershafts I I have the dashers W W, of lan .ordinary form, secured to their lower ends, and pass up through holes in the covers h Zz, and through slots in the cross-piece Y, where they are secured by a strappiece, O, which is pivoted to the cross-piece Y at one end, by a staple, c, the other end being secured, by the staple d, in the cross-piece Y, and the hasp' P, on the strap o, in a manner readily seen. c

4The upper endsA of the dasher-shafts I I are of a circular cross-section, and have the springs I I placed on them, as shown.

They project Vthrough holes in the cross-piece H, and the springs I I bear against the same piece, so that, by changrn g the height of said crosspiece, by means of the pins V Y, which may be inserted in any of the holes in the. uprights A A, the tension on the springs I I may be varied at pleasure.

The operating-wheel L is hung on a shaft, J, which is arranged in boxes on or in 'the upper side-pieces F F, said shaft J being provided with a crank, K, or any other suitable device for applying the power.

Thepins M M and N N are inserted in the two sides of the wheel L, on lines at right angles to each other, as seen in g. 5, and as the shaft J is`revolved, they strike against the arms ff in the dasher-shaft I I, (see g. 4,) and raise said dashers, until the pin M or N is drawn from under the arm f by the revolution of the wheel L, when the dasher I is forced down by the spring T.. c

A piece of rubber, e, is passed through a mortise in the dasher-shaft I, and strikes on the cross-piece Y, thereby stopping the downward movement of said dasher in an easy and effectual manner.

From the foregoing description, it is readily seen that,

by tin-ning the crank K, a'u alternate up-and-down movement ofthe dasher-shafts I I is effected, and through the action of the dashe'rs W W, the'cream in the churn R is thrown into violent agitation, and quickly churned. The manner of removing the dashers `I W, churncovers h 1t, and churn It, for the purpose of cleaning the same, is too obvious to any person skilled in the art, to require particular description.

Having thus fully described our invention,

What we claim as new, and desire to secure by Let ters Patent, is

1. The peculiar arrangement and combination of the churn R, with broad inner rim g, covers .lt 71cross-bar S, .press-screw Q, crosspiece Y,l dashers I W, I W, and strap O, with haspl P and connecting-,staples c d, the several parts being arranged as and for the purpose specified.

2. The peculiarl arrangement and combination of the churn-dashers I YV, I W, with arms ff, rubber stops c e, and springs T T; the adj ustable crosspiece EI and uprights A A with pins Y Y; and operating-wheel L with pins M M and N N; the several parts being arranged as and for the purpose specied.`

As evidence'that We claim the bregoing, we have hereunto set our hands, in presence of two witnesses, this 29th day of J une, A. D. 1868. p
