IMPROVEMENT IN cHURNs.

The Schedulerefen-ed to Vin'theeia Letters Patent and making part of the sama To all persons to whom these presents mtl/y come:

Be it known that I, EBENEZER COLEMAN, of Woburn, in the county of Middlesex, and State of Massachusetts, have invented a new and useful Improvement in Churns; and dohereby declare the same to be fully described inthe following specication, and represented in the accompanying drawings, of which-.- l

,Figure l is a side elevation,

Figure 2 a front elevation,

Figure 3, a transverse section, and

Figure 4, a longitudinal section of a churn provided with my improvement.

The reservoir of this churn is so supported or pivoted to a frame, as to be capable of being vibrated therein, While the dasheris held stationary by such frame.

In carrying out myirnprovemen-t, I have `combinedl with the dasher, the vibratoryreservoir, and their mail supporting-frame, a separate movable arch, yoke, o1 bail, provided withy tenons, to'enter mortises in the posts of the main frame. This arched frame, yoke, or bail, while serving to support the dasher and the vibratory reservoir, enables them to be veasily detached from the main frame, for convenience of package or transportation of the two. It'also admits of the dasher being easily separated or removed from the reservoir. Furthermore, the arch serves as a bail', or handle 'for the reservoir, to enable a' person to easily move it from place to place. Besides this, Iv have combined together and with the reservoir and its supporting-frame two distinct means of operating or vibrating the reservoir, it being capable of being operated by either or both of them, as occasion may require.

In the drawingsy Ay denotes the vibratory cream-reservoir, which is arranged Within the arch B, and pivoted thereto, or in other words, is supported by journals la b, extending from opposite sides of it, and `going through bearings c el in the arch.

This arch, at its extremities, is provided with tenons, e e, which enter corresponding holes, or mortises ff, made in the tops of the vertical posts g g of a main frame, Ofconstructed as represented in the draw- The dasher, Vshown at D, has a tenon, h, on the upper part of .its rod fc3. This tenon goes through and extends above the central part of the arch, and is` notched, to receive a lever-catch, E, which is pivoted to the top of the arch, such catch and notch serving, with the shoulder and down, A person at the crankand another at the lever. By such k of the tenon, to hold4 the dasher-rod in connection with the arch, and thereby support the dasher in a stationary position within the reservoir.,

' The mouthl ofthe reservoir is provided with a cover, m, which has4 a long slot, n', made throughit, to receive the dasher-rod, and allow of the reservoir being vibrated.

There is xed to one side of the reservoir a lever, F. One ofthe journals of the reservoir passes through the said lever. The same may .be saidwith respect to a joint-pin, or stud o, which extends .from the side of the reservoir. Y Thisjont-pin goes through a connecting-rod, p, near its upper end, such rod, at its lowerend, turning on or being applied to the wrist of a bell-crank, q, extending from a shaft, r.

This shaft goes 'throughthe main anie, has bearings in the posts thereof, and is provided, at one end, with a crank, s, the whole being as shown in the drawings. 1

By laying hold of the crank s, and revolving it and the shaft r, a reciprocating or vibrato'ry motion will be imparted tothe churn-reservoir. This m'otion Imay also .be given to the reservoir by means of the lever F, or by a person laying hold there'of, and moving it up Thus the churn may be worked by one means, two children may work the reservoir, when one could not'well do it by rneans of the crank or the lever alone.

I make no claim to a stationary dasher and a vibratory 'reservoir applied thereto; but

I claim the combination and arrangement lof the movable arch, or bail B, separate from the supportingframe C, with such frame C, thedasher D and the vibratoryreservoir A, provided lwith mechanism for osci1` lating it, as set forth. y

'I alsd claim the combination and arrangement of the working-lever F, with thevbratory reservoir A, and the cranked shaft lr', and connecting-rod p, applied tto such reservoir and the supporting-frame 0, as set orth.

I also claim the combination and arrangement of the catch-lever E and the mortised movable arch, or bail, with the notchedl dasher and the vibratory reservoir, to operate together as set forth.
