ELI A. RUDASILL, OF SHELBY, NORTH CAROLINA, ASSIGN OR OF ONE-HALF TO JOHN O. BEAM, OF SAME PLACE.

CHURN'.

SPECIFICATION forming part of Letters Patent No. 402,976, dated May 7, 1889.

Application filed November 2, 1 8 8 8.

To all whom it may concern:

Be it known that I, ELI A. RUDASILL, a citizen of the United States, residing at Shelby, in the county of Cleveland and State of North Carolina, have invented certain new and useful Improvements in Churns; and I do hereby declare the following' tobe a full, 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, which form part of this speciiication.

My invention relates to that class of devices known as reciprocating churns, and has for its object to provide means for a more easy and regular stroke of the dasher without friction than has heretofore been furnished, and also to provide means for forcing air to the bottom of the cream at each ascending movement of the dasher, which, together with peculiarly-constructed beaters, produce violent agitation of the cream, reducing the usual time required for churning; and it consists in the construction and combination of parts hereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective view of my invention. Fig. 2 is a side View of the upperpart thereof with the dasher broken away. Fig. 3 is avertical central section through the standard or support and driving mechanism. Fig. iis across-section through the clip connecting the dasher to the guide-bar on the line :t of Fig. l. Fig. 5 is a vertical section of the two-part tubular dasher, showing a valve therein. Fig. 6 is a perspective view of a slightly modiiied form of the upper portion of my device. Fig. 7 is a vertical section of the same. Fig. 8 is a detail view of the slotted guide-bar or gib, having a recessed cross-barthereon; and Fig. 9 is a side view of a balance-wheel adapted to be applied to my modiiied construction.

Like letters of reference refer to corresponding parts in each figure of the drawings.

A represents the cover of a churn, having its body shown in dotted lines below. To the top of the cover is secured a foot, B, having a sleeve or nut on its upper sideintegral therewith, into which is screwed a vertical rod, a.

Serial No. 289,804. (No model.)

A standard or support, C, having an eye, b, integral with its side is adj ustably secured upon the rod a by a set-screw, c, through the side of the eye-piece. The standard C extends at some distance above the rodv a, and has its upper end, d, turned downward vor parallel to its body, to form a bearing in its end and body for a journal, D, which carries apinion, E, thereon between the turned end and body of the standard. To the side of the central portion of the standard O there is secured a journal, e, which carries a gear wheel, F, that meshes with the pinion above, and is operated by a crank attached to one side of the wheel. On the opposite side of the standard from the driving-gear the journal-bearing is extended outward to form a collar, f, between which and the hub g of the iiy-wheel there is a space for a guide-rod or gib, hereinafter described. Y

The fly-wheel G on or near the end of the journal D is constructed with one side heavier than the other to provide a balance to regulate and steady the motion of the pitman. In the light side .of the fly-wheel there is a slot extending from near the periphery toward the center, in which the pitman H is adjustably secured by a bolt and thumb-nut, h, for the purpose of regulating the length of its throw.

On the lower portion of the opposite side of the standard C from the driving-gear there is formed integral with the standard a dovetailed projection, I, having its inclined sides z' extending toward each other and the body of the standard. Upon the outer face of this dovetailed projection there is attached a guide-bar, J, which may be cast or plate metal, by means of holding-clips j, which extend from the bar and are bent around upon the inclined sides t' of the projection, where they slide up and down upon these faces as the bar is moved.

The upper portion of the guide-ban J is slotted or forked from its top downward about two-thirds its length, and the forked sides K of the slotted portion extend upward upon each side of the journal D of the pin` ion, and are supported and held in place while in operation, as against any lateral movement, by the end of the collar f of the standard and the hub g of the fly-wheel.

Ipo

Tothe lower end of the slotted guide-bar J there is a pin, 7s, rigidly secured, which extends outward and receives the lower end of the pitman H upon its reduced portion,which is held thereon by means of a screw-nut on the end of the pin.

A coupling-arm, L, is riveted or otherwise rigidly secured to the side of the guide-bar J, at a short distance above its lower end,which extends outward beyond the edge of the bar at right angles thereto, forming a semicircular socket, l, that receives the dasher, which is held therein by means of a thumb-screw, M. Lugs m are formed integral with the guide-bar above and below the coupling-arm L, which are bent outward at right angles to the face of the bar to provide a bearing-surface at the edge of the bar for the dasher-rod to rest against and steady its attachment in the coupling-arm.

The dasher-rod is composed of an upper tubular stem, N, which is adjustably telescoped within a lower tubular stem, O,which has secured to its lower portion, one above the other, two conical beaters, P, the lower edge of the bottom beater being on the same plane with the lower end of the stem O,while the lower edge of the upper beater is at the uppermost portion of the lower beater. The beaters are each provided with a series of vertical slots, p, extending from near their bottoms to the top, with perforations between the slots at their lower ends.

The lower inelosed end of the upper tube, N, of the dasher-rod is provided with avalve, n, of the same diameter as the tube, which loosely rests against its end and is held in position by a cord, o, attached within the tube for the purpose of permitting air to enter the dasher when it makes its upward throw.

In operation as the driving-gear is worked the fly-wheel G is revolved, carrying the pitman, which is pivoted to the bottom of the slotted guide bar or gib J, which slides on the standard and is thrown up and down with its forked upper end passing on each side of the journal of the iiy-wheel, and between its hub and the proj eeting collar of the standard C, giving it a steady vertical motion, carrying the dasher, which is rigidly secured to its lower portion.

By the construction of the dasher it will be observed that it can be adjusted to any desired length by moving the tubes in or drawing them out from each other, and the valve lowered or raised, as may be desired, the lower tube, O, being extended downward through the lower beater, P. The air is forced out of the tube at a point below the beater, so that when the dasher ascends the valve is opened, creating a vacuum in the body of the cream which is quickly iilled by a rush of air 4 down through the tubular dasher, and as the downward stroke is quickly made the valve is closed, confining the air within the cream, which produces an upward pressure and forcibly ejects the cream into the descending conical beaters and through their openings, producing violent agit-ations of` the whole body.

As illustrated in Figs. 6, 7, and 8 of the drawings, I may slightly modify a part of the driving mechanism of my device without departing from the spirit of my invention.

ln place of the pitman l-I, heretofore described as connected with the ily-wheel G and lower part of the guide-bar or gib J, the guide bar may be provided with lateral arms R, secured to the face of the sides K of its slotted or forked portion about midway its length, or be cast in the same piece therewith. These arms are made to extend at right angles to the forked sides K, and have their faces provided with a deep broad groove, r, to receive the enlarged end of a wrist-pin, S, which is fixed in the adjusting-slot of the ily-wheel. By this construction of guide bar or gib, as the fly-wheel is turned the pin S works in the grooved arms R from one side of the vertical slot to the other, sliding the gibup and down on the dovetailed projection of the standard C, with its upper slotted end working over the journal D, carrying the dasher attached thereto, as hereinbefore described. This form of driving-gear is more especially adapted for heavy churns, as greater leverage is produced by dispensing with the pitman and taking the leverage directly from the fly-wheel. Additional power may be added, if desired, by applying a balancewheel, T, to the outer side of the flywheel G, which may be secured in place by a screw-nut, t, on the end of the journal D, as shown in dotted lines in Fig. 7.

Having fully described my invention, what l claim as new, and desire to secure by Letters Patent of the United States, is

l. The combination, with the adjustable standard having its upper end turned to one side to form bearings for each end of the upper journal, and provided with a dovetailed projection on its opposite side, of a verticallysliding guide-bar slotted in its upper end and secured to the standard by holding-clips on the inclined surfaces, the upper or forked ends of the guide-bar being held in position by the upper journal and the driving-gear, as set forth.

2. The combination, with an adjustable standard having a dovetailed projection on one side, of a vertically-sliding guide-bar slotted in its upper part and confined to the inclined surfaces of the standard by clips,.

the arms of the slotted part of the bar being held upon each side of the upper journal and between the collar of the standard and hub of the iiy-wheel on said journal, as set forth.

3. The combination, with a standard having a dovetailed projection thereon, and a vertically-sliding guide-bar secured thereto, said bar being slotted in its upper part and its arms passing on each side of the upper journal, of a two-part tubular dasher secured to the guide-bar and having conical beaters IOO IIO

on its lower end, one above the other, as set forth.

4. The combination, with an adjustable standard havinga dovetailed projection on one side, a vertically-sliding slotted guidebar having its forked ends extending on each side of a journal above, and between the collar of the standard and hub of the fly-wheel on said journal, said fly-wheel having a pitman connected thereto and to the lower end of the guide-bar, of a coupling-arm secured to the guide-bar, having a socket therein holding a two-part tubular flasher-rod having conical slotted beaters one above the other on its lower portion, said upper dasher-rod being adjustable Within the lower and having an air-valve on its inclosed end, as and for the purpose set forth.

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