'ro ALL wnon 1T MAY coNonRN;

Be it known that I, MARQUIS D. WALLACE, of White Creek, county of Washington, Stute of New York, have invented new and useful improvements in Chur-ns; and I do hereby declare the following to be a full, clear, and exact description of the same, sufficient to enable one skilled in the art to which it appertains to construct and use the same, reference beinghadto the accompanying drawings, which are made part of this specification, and in which thc same letters indicate similar parts.

Figure 1 is a vertical central section.

Figure 2 is an elevation of the upper portion.

The vertical motion of the dasher is effected by the engagement of the driving-wheel with the pinion on lthe flywheel shaft, a wrist on the ily-wheel being connected by a rod with the dasher-shaft, which is telescopic, so as to admit of extension to enable the dasher to act within diferentkportions of the vertical height of the churn, and it is also adjustable hy the shifting of the wrist in the face or a. spoke of thely-wheel, so as to graduate its length of stroke. V

In the drawings, A is the sill, and B the upright' of the frame, upon which the churn C and moving-parts of the machine are supported. The upright B has a branch, Z1, so thatthe main shaft D has two supports. On the outer end is the pinion N, whose teeth are engaged with those of the driving-wheel E, whiclrhas a crank or handle, c, and on the inner end of the shaft is the tly-wiiel'el F, to whose wrist G is attached the connecting-rod II, whose lower end is pivoted by a screw to the dashershaft I. The dasher-shaft I may have a guide, J, which is supported from the stem B and a post, K, inthe case of large churns, but in the case of small churns the guide .Inlay be dispensed with, as the lid E ofthe churn C will be suiiicient for 'the purpose. 'lhe churn-dasher is made telescopic, the outer and upper portion z' being tubular, while the dasher M is attached to the central stem which is vertically adjustable in the tube, being maintained in the required position by the set-screw lm. In the face of the ily-wheel F, or in one of its spokes, a-'re several holes at different distances from its centre or axis of revolution. The wrist G, which connects with the plunger-shaft, is I'tted to such one of these holes as may be desired, according to the length of stroke desired. This will vary with the quantity of cream or milk, and with other circumstances. To prevent the danger of catching the fingers or the clothes in the gearing the driving-wheel E has cogs on its interior perimeter, which engage with the teeth of the pinion N. The gearing may be driven by a band upon the wheel E proceeding from a dog-power or other motor. It will be perceived that by the adjustment of the wrist, which determines the length of the stroke of the dasher and the adjustment of the stem of the dasher, that the latter may be made to operate in such portion of the vertical height of the churn as may be considered desirable, either a short, quick stroke near the bottom or near the top, or a long stroke extending from the bottom to the top, or between such points as may be desired, according to the amount andl character of the contents. When running by belt the crank-handle e of the wheel E will be removed, and the dasher can be removed from the churn byvremoving the screw which fastens the connecting-rod to the dasher-shaft and allowing the latter to subside below the guide, when the churn is slipped out and the lid and dasher removed. p

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the frame B 6, andadjustable telescopic shaft I, constructed and operating as described.

MARQUIS D. WALLACE.
