Lette/rs Patent No. 101,936, dated April 12, 1870.

IMPROVEMENT IN CHURNS.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:

Be it known that I, THOMAS B. STEPHENS, of Washington, in the State of Iowa, have invented a certain new and useful Improvement in Churns; and I do hereby'declare the following to be a clear, full, and exact description of the same, reference being had to the accompanying drawing and to the letters and marks thereon, which said drawing forms part of this specification and represents a churn constructed under my invention Figure l thereof being a view by longitudinal section, and

Figure 2, a top view of the churn.

In both of these figures where like parts are shown, like marks and letters are used to indicate the parts.

My invention is of the character of an additional improvement to the churn of Alexander' Stephens, on which a patent was granted bearing date November 29, 1864, and which is set forth thus: This invention consists in a churn having two upright dashers placed side by side in the body of the same. In connection therewith there are two pulleys, placed in a similar manner upon a horizontal shaft connected by bands, for producing a rotary motion to the dashers, and operated by a crank.

This churn of Alexander Stephens has certain defects which myinvention corrects, and whichare mainlyv due to the position of the dashers in the shafts, to the dashers being unperforated, and to the means for giving rotation to the shafts and dashers.

The dashers, a, of my churn are perforated, allowing amore complete circulation of the fluid contents of the churn, and, as one piece, extend nearly from the bottom to the top or lid of the churn, thus being adapted' to the full and perfect agitation of the fluid,

whether the churn be full or partly occupied only, answering as well, therefore, for a small as for a large churning.

The dashcrs are properly secured to arms, b, which pass through slots in the shafts c, the shafts having bearing, d, attached to the bottom c of the churn.

At the upper end of the shafts there are beveled pinions, f, which gear into the beveled wheels g on the horizontal shaft h, to which the crank i is affixed.

The lid or cover of the churn is of two pieces, j and k, the one, j, being hinged to the side piece of the churn, and the other, k, being fitted into a recess in the end pieces and front piece of the churn.

At the point of union of the two'parts of the lid, recesses, l, are made to receive the contracted portion, my, of the shaft.

Under this arrangement of the different parts and pieces here named, the shafts and dashers may readily be detached from the interior of the churn and the beveled wheels and crank-shaft be turned oil", so that free and easy access may be had for the removal of the contents of the churn.

I am aware that as individual pieces or parts of a churn, there is no one of the devices or means here named that is new, and I do not, therefore, claim any one of the parts individually; nor do I claim the gen- A eral arrangement of vertical or perpendicular shafts with flashers operated by belt and pulley on a horizontal' shaft; but

' What I do claim, and desire to sccureby Letters Iatent, is-

The arrangement of the horizontal shaft with beveled wheels and vertical or perpendicular shafts with pinions and long perforated dashers, when such shafts and their parts are arranged with the divided lid or cover, as herein recited.

This specication signed this 17th day of August, 1869.

THOMAS B. STEPHENS.
