JOHN W. FERRENBURG, OF HEGE, INDIANA.

CHURN.

SPECIFICATION forming part of Letters Patent No. 403,337, dated May 14, 1889.

Application led January 17, 1889. Serial No. 296,581. (No mgdel.)

To @ZZ whom it may concern,.-

Be it known that I, JOHN W. FERRENB'URG, a citizen of the United States, residing at Hege, in the county of Jennings and State of In'- diana, have invented certain new and useful Improvements in Churns, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain improvements in churns of that class in which the dasher is mounted on a vertical shaftand is oscillated or partially rotated back and forth to agitate the cream; and it has for its objects to provide for shifting the gearing by means of which movement is imparted to the dasher, so that the levers by which the gearing is driven may be operated either in a vertical or horizontal plane, as may prove more convenient, and to provide for elevating the drivinggear from the churn when necessary, as more fully hereinafter set forth. These objects I attain by the means illustrated in the accompanying drawings, in which- Figure 1 represents a front elevation of my improved churn, showing the operating-gear in a vertical position. Fig. 2 represents a side elevation of the churn, showing the operating-gearing partly thrown back in dotted lines. Fig. 3 represents a top view of the churn, showing the operating-gear in vertical position. Fig. 4 represents a similar view showing the operating-gear in a horizontal position. Fig. 5 represents a transverse vertical sectional view of the upper portion of the churn and the gearing. Fig. 6 represents a detached sectional view of a portion of the frame which supports the standard carrying the driving-gear segment and a portion of said standard; and Fig. 7 represents a sectional view of said frame and standard, taken at right angles to the view shown in Fig. 6.

Referring to the drawings, the letter A indicates the churn-vessel, which sets upon a suitable base, B, when in use.

B indicates a vertical dasher-rod, which is suitably stepped at the bottom of the churn, and which passes at its upper end through the top C 0f the churn at its center. Within the churn are located the dasher-blades D, which are secured to the said vertical rod B', and near the top thereof is secured a cogframe are pivoted, in suitable bearings, the

journals G of a swinging frame, H, which eX- tends over the churn, the part immediately over the churn being arched and provided with a bearing for the upper end of the vertical dasher-shaft, as shown. When the churn is in use and the swinging frame is down, as shown in Fig. 5, the bearing sets over said end of the shaft, but when elevated, as shown in dotted lines in Fig. 2, it releases it, so that the churn may be removed or its top taken oif when necessary. When the frame is elevated, it is supported by means of a rod, I, hinged to the vertical frame, the upper end of the rod being bent, as shown, so as to form a shoulder thereon, which will support the hinged frame when the extremity of the rod is inserted through a suitable aperture, a, therein, as shown in Fig. 3. At each side the hinged frame H is provided with slots K, through which pass adjustable eyebolts`L, confined below by means of suitable screw-nuts, and to the upper ends of said eyebolts are hinged the lower ends of a shifting standard or frame, M, which carries the segment N, which is pivoted to a bolt, P, passing through apertures in the swinging standard or frame M.

The segment is provided with a series of cogs or teeth, R, which extend beyond its edge and down the periphery of the same in such manner that the segment will intermesh with the pinion E on the dasher-rod when the said standard M is either in a vertical or horizontal position. At each side the segment is provided with laterally-extending arms S, having suitable handles, whereby it may be operated. The said standard M is held in a vertical position by means of detachable brace N, which is released at one end and thrown back when the said standard or frame M is placed in a horizontal position.

To facilitate the action of the segment, a

spring, T, may be connected to one side thereof and to the side of the standard or frame M, as shown in Figs. 1 and 2.

The letter U indicates an aperture in the swinging frame H, in which bolt P is secured when the standard or frame M is in a horizontal position, so as to hold it down.

The letter V indicates two brace-rods, by means of which the vertical supporting-frame is held steadily.

In arranging the churn for use the vessel A is placed upon the base and the swinging frame His brought over it so as to engage the upper end of the dasher-rod. If the segment is to be Worked vertically, the standard M is moved up so as to bring the face of the segment and cogs thereon into gear with the pinion on the flasher-rod, the said frame being adjusted in position by means of the eyebolts and nuts before mentioned, and braced vertically by the brace. VVh'en the segment is to be Worked horizontally, the brace N is disconnected and turned back, the standard M is turned down to a horizontal position, and the segment bolted to frame H, as shown in Figs. 4 and 5 of the drawings.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s- The combination, with a suitable base and support and a churn and flasher-rod, the latter provided with a pinion, of a frame, Il, pivoted to the said support, and a standard, M, pivotally attached to the said swinging frame, this standard carrying a pivoted toothed segment adapted to engage the said pinion upon the dasher-rod, the said segment being provided with cogs bothnpon its face and periphery, as and for the purposes herein set forth.

In testimony whereof I aiiix my signature in presence of two Witnesses.

JOHN W. FERRENl-SURG.
