. METALLIC CHURN.

SPECIFICATION forming part of Letters Patent No. 542,026, dated July 2, 1895.

Application filed November 30, 1894- Serial No. 530,416- (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL D. PALMER, a citizen of the United States, residingat Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Metallic Chorus, of which the following is a specification.

' The object of this invention is to construct a metallic churn in two sections, a pair of bails supported by one of the sections and a fastening device consisting of a lever having a pivotal connection'with the other section,

provided witha projection supporting the center portion of the bail while being carried past the dead-center of the lever.

In the accompanying drawings, Figure 1 is an elevation of a churn, showing my improve- Fig. 2 is an elevation of the churn as seen when looking against the end of one of the trunnions. Fig. 3 is an enlarged section of a portion of the two sections and angleiron ring at their junction. Fig. at is an isometrical representation of the fastening device secured to the upper section. Fig. 5 is a vertical section of the fastening device.

The churn-body shown in the drawings is substantially the same as that shown in an application filed by me September 8, 1894., Serial No. 522,429, and a brief descriptionof its construction will suffice, as the invention covered by this application relates to the fastening device for holding the sections of the churn-body together.

The sections 1 and 2 of the ch urn-body are substantially the same so far as size and shape are concerned, the lower section 1 having the metal of its open end bent to form two sides of a receptacle for a packing-ring 3, the outer surface ofithe receptacle being formed by the vertical side of an angle-iron ring 4, the horizontal portion of the ring being con-' nected to the horizontal portion formed from the lower section. From opposite sides of the angle-iron ring extend trunnions 5, one being fitted to receive a crank. From the upper surface of the angle-iron ring rise perforated ears 6, four in number and located equidistant apart, and each pair of ears support a bail 7 in a pivotal manner.

The upper section 2 of the churn-body has an annular ring 8, held in place by the material of its open end, and rests upon the packprojections 16.

ing-ring 3 when the sections are placed together.

The fastening means for holding the sections together is secured to the upper section of the churn-body, and consists of a base-plate 9, secured to the outer surface of the upper section of the churn-body. A strip of metal is bent around the base-plate, having its ends turned outward and perforated, forming lugs 10. A support 11 has a pivotal connection with the lugs by a bolt 12, passing through the parts. This support has a lengthwise screw-threaded opening 13. A lever 14 has its lower end screw-threaded and its upper end provided with a cross-bar 15, and from the lever near its screw-threaded end extend A jam-nut 17 is placed upon the screw-threaded end of the lever. The screw-threaded end of the lever is turned into the screw-threaded opening of the pivoted support 11 and the lever set so that the projections will extend at right angles to the pivot-bolt 12 when the jam-nut is turned down, holding the lever .in'such position as shown in the drawings. The bails are turned down into the position shown at the righthand side of Fig.2, and the levers are also placed in the position therein represented in solid lines. The upper section is placed in position in contact with the lower section. The bails are then raised until they pass over the end of the levers, when the levers are raised, which will cause the bails to come in contact with the levers at the junction of the projections with the levers, as shown in dotted lines, Fig. 2. The further upward movement of the levers will carry the center portion of the bails over the center of the pivot of the levers, when the projection on the inside of lever will come in contact with thehase-plate 9, holding the balls in the position shown in solid lines at Fig. 1 and as shown at left-hand side of Fig. 2. While the bails are over the deadcenter of the lever the two sections of churnbody will be drawn together with the greatest force, and after the dead-center has been passed the force will be slightly lessened, but not to such an extentas to form a leak at the junction of the sections, and upon separating thesections the levers will be moved downward, carrying the center portion of the bails over and outside of the dead-center of the levers. By means of the cross-bars 15 at the free end of the levers handles are formed, by which the upper section of the churn-body may be carried when separated from the lower section, and the projections 16, coming in contact with the base-plate 9, will hold the free ends of the levers clear of the sides of the upper section.

By the lever having a screw-threaded connection with the pivoted support it may be adjusted lengthwise, and the jam-nut will hold it when adjusted, and by the employment of two projections extending from opposite sides of the lever either may be used to support the bail. As the leveris adjusted lengthwise the projections will be moved toward or from the pivot of the lever, which will diminish or increase the pressure brought to hear at the junction of the sections.

I claim as my invention 1. A churn composed of two sectionsjoined at their open ends, bails pivotally connected to one of the sections and a fastening device consisting of a lever having a pivotal connection with the other section provided with a'projection supporting the center portion of the corresponding bail while being carried over the dead center of the lever.

2. A churn composed of' two sections joined at their open ends, bails pivotally connected to one of the sections, and a fastening device consisting of a lever having a pivotal connection with the other section, provided with a projection supporting the center portion of the corresponding bail while being carried over the dead centers of the lever, the free end of the lever being in handle form.

3. A churn composed of two sections joined at their open ends,a bail pivotally connected to one of the sections, a base plate secured to the other section, lugs extending therefrom, a support having apivotal connection with the lugs, a lever having a screw thread connection with the support and provided with a projection supporting the bail while being carried over the-dead center of the lever, and a jam nut located upon the'levcr engaging the outer end of the support.

4. A churn composed of two sections an SAMUEL D. PALMER.
