No. 215,850.. Patentedl May 27, 187,9.




Specication forming part of Letters Patent No. 215,850. dated May 27, 1879; application iiled January 24, 1879.

To all lwhom 'it may concern:

Be it known that I, MosEs R. WHELCHEL, of Hartville, in the countyof Vrightand State of Missouri, have invented certain new and useful Improvements in Ohurns; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying' drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a front elevation of my improved churn. Fig. 2 is a vertical section of the saule. Fig. 3 is a plan view ot' the bottom of the churn.

In the drawings, A represents the main body of the churn, which, in its general conformation, may be constructed in the ordinary or in any desired form.

Upon th ebottoxn of the churn there is a step, a, which receives the lower end of the dashershaft. This step has a central cylindrical recess, al, in which the dasher-shaft rests when at work.

In order to readily guide the shaft into said recess al, I form in the step a several radial slots or grooves, a2 a?, leading' into the central recess, a'.

B represents the dasher-shaft, and b b are the radial arms or blades. Bl is a mortise or recess formed in the upper end of shaft B.

The churn is supported in a frame consisting of the bottom O, sides O OZ, and a top, O3. c c c c are cleats secured to the opposite side walls, (Ll O2, respectively.

D is the lid or cover of the churn, adapted in size and shape to be guided and held in place by the cleats c c c c. After the lid has been placed in proper position it is held from slipping laterally by pins d d. The lid is provided with an aperture directly over the recess al, through which the flasher-shaft B passes.

The dasher is operated as follows: E E are uprights or standards, eXtendingfrom the walls Ol O2, and they are joined at the top by a crossgirt, El, the whole forming a supplemental frame to support the drivin g parts ofthe churn. F is a shaft, mounted in this frame atits upper or outer end, at a point directly in line with the recess a* and with the above-de scribed aperture in the churn-lid. This shaft F passes through an aperture in the top O3 of the churn-casing, adapted to the purpose, and it is square or tiattened atits lower end, to fit into the mortise or slot Bl inthe upper end of the dasher-shaft B. GGare pinions attached to shaft F, to impart rotary motion thereto. H is a wheel, mounted in the frame E E1 E2 on a shaft at rightangles to the shaft F. This wheel His provided with a mutilated or broken gear, (shown at h,) meshing' with the pinions G G and rotating them alternately. Power is applied to the wheel I-I atX by a crank or by other suitable means. A continuous rotation of wheel H in one direction will, through pinions G G', give an intermittent rotary inotion in opposite directions to shaft F and dasher B b.

Vhen the operation of churning is completed the churn can be removed after withdrawing the pins (l d and uncoupling the shafts B and F, as the lid D will then slide freely between the cleats c c.

/Vhat I claim is- The combination, with the shafts F and B and the cover I), of the frame O' OZ and theretaining' parts c c d, substantially as set forth.

In testimony that l claim the foregoing as my own I affix my signature in presence of two witnesses.
