(Xo model.)

Application filed January 12, lli. Serial No. 188.340.

, .T r/,ZZ whom it may concern,.-

Be it known that I, Isaac WHTTTEN WAL- TER, of Newberry, in the county of Newberry and State of South Carolina, have invented certain new and useful Improvements in Cburns; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, marked thereon, which form part of this specification, in which- Figure l is a side view of my invention applied to a churn. Fig. 2 is a central vertical section of the same on line :r cv, Fig. l. Fig. 3 is a horizontal section on line y y, Fig. l. Figs. et and 5 are details.

This invention relates to improvements in churn attachments, and has especial reference to that class by which the agitating of cream in alternate opposite directions is effected; and it consists in the novel construct-ion and arrangement of the parts hereinafter described, and pointed out in the claim.

In the drawings, A represents the east-iron upright frame, which supports the churndasher and its actuating mechanism. This frame is of sufficient height to admit of a vessel in which the milk is to be churned to rest beneath its top bar upon a door or board, A', to which the lower ends oi' the frame A are suitably bolted.

To the side pieces, a a, of frame A, near the center thereof, are bolted the ends of a strip or band of metal, b, which is bent in proper shape to hold therein onehalf of a churn-can. At one side of the can, on band b, is suitably hinged a strap, b', the free end of which is adapted to be connected to the band b by a suitable adjustable retaining device at the opposite side of the can, as shown in the drawings.

By means of bands b and b it is obvious that cans or vesseis of different diameters may be securely held in position within the frame 'A during the operation of churning, and may be easily and readily removed therefrom when desired. The preferable manner of forming the said retaining device is by so connecting the hinge end of strap b to strap b that it will open easily outward. Then, by introducing the headed bolt orscrew b through openings in and to the letters of referencethe straight extensions b5 b* of the straps b l1', and putting on the threaded end of the said bolt a thumbnut, b5, the straps can oe opened or closed to receive cans of varying diameters. From the upper horizontal bar, a', of frame A, over the center thereof, rises an inverted Y-shaped bracket, C, which is cast integral with the frame, the bifurcations of this brach et forming, with bar a', an opening, G2, in which plays a pinion, D, hereinafter referred to. The upper end of bracket C is formed into a proper bearing for the journal of a segmental rack, F, hereinafter described.

Atthe top of opening C2 is formed, in bracket G,a vertical journal-bearing for the upper end of a short shaft, C', which has its lower journal in a bearing formed in the bar a. On this shaft C', above baro', is secured a pinion, D, which serves both to support the shaft vertically and rotate the same. The lower end of shaft C passes through bar a', and is formed into a socket, c, angular in cross-section, and provided with a thumb-screw or similar device for securing the upper end of the churndasher E within the saine, asshown.

F designates a segmental rack, which has its bearing j ournaled in the upper end of bracket C, as described, and suitably secured therein by a washer and nuts. The rack is preferably but a quarter of a circle in size, and its cogs engage the pinion D when in position, and thereby actuate the same when the rack is vibrated by means of its handle d. This handle d may be cast integral with rack F; but is preferably made separate and bolted thereto, as shown. This admits of a new handle being substituted should the old one be broken without necessitating the purchase of both handle and rack. The outer arms, ff, of rack Fare provided with lugs f', which impinge on a flange of bracket C, as shown, and serve to prevent the rack from being forced out of engagement with pinion D when the rack is vibrated.

G designates a short bracket, adapted to be secured to the side of the bar a within the bifurcations of brackets C. This bracket Gis formed with an upward extension or arm, g, which is preferably cast integral with the saine, but may be made separate and secured thereto. This arm g acts against the lower outer side I CC of the rack -F, and serves to prevent the rack from becoming disengaged from pinion D, as shown.

rIhe churn dasher E ispreferably of the form shown in Fig. l," with two or more depending arms or beaters, c', which gradually lessen in thickness from top to bottom. The upper end, e, of the dasher is formed to correspond with the interior of the socket c, in which it is secured by the described means. It will be observed that the lower ends of the dasherblades are unsupported in the churn-can, and that therefore various kinds and sizes of cans may be used. On the part e, below the socket 0, may be placed a washer, e`, which prevents splashing of milk upon the operator.

The operation of the invention is as follows: The can or vessel containing the milk to be churned is placed in position within the frame and secured by the bands, as described. The

dasher, having the cover ofthe churn slipped I contemplate making the frame, as de- 3o scribed, with its accompanying parts, and selling the same as an article of manufacture independent of the milk vessel or churn.

I am aware that churn attachments have been made combining some features of the invention. Therefore I make no broad claims; but,

Having described my invention, I claim- The combination of the cast-iron frame A, having a base, A', and securing-bands b b', and Y-shaped bracket C, cast integral with the frame, segmental rack F, provided with stoplugs f', journaled in the upper end of said bracket shaft C', journaled in the lower portion of bracket C and in the top bar of the frame, pinion D, engaging rack F, a suitable retaining device formed on the end of shaft C', for securing the churndasher thereto, and bracket G, having an arm, g, to prevent 1ateral disengagement of the rack and pinion, all substantially as and for the purpose specified.

In testimony that I claim the foregoing as myown I affix my signature in presence of two witnesses.

ISAAC WHITTEN VALTER. W'itnesses: SAMUEL D. CHERRY, SAML. VARD YOUNG.
