IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 126,052, dated Apri-l 23, 1872,' antedated April 2, 1872.

SPECIFICATION.

To all whom it may concern:

Be it known that I, JOHN D. HARRISON, of Middletown, in the county of Butler and in the State of Ohio, have invented an Improvement in Churns and do hereby declare that the following description, taken in connection with the accompanying plate of drawing hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvement, by which my invention may be distinguished from others of a similar class, together with such parts as I claim and desire to secure by Letters Patent.

My invention relates to that class of churns in which the upright dash is used; and the nature thereof consists in providing the balance-wheel by which the dash is operated with an adjustable box containing a ball and socket, by means of which the length of stroke of the dash may be accurately adjusted, and in the provision of means for clamping the churn in position, as hereinafter shown and described.

1n the accompanying plate of drawing, which illustrates my invention and forms a part of the specification thereof, in which correspond- -ing parts a-re illustrated by similar letters,

Figure 1 is a view in perspective. Fig. 2 illustrates in detail the adjustable ball-andsocket joint. 'Fig'. 3 represents the device by means of which the churn is locked in position.

Letter A designates `the balance-wheel, provided with a radial aperture, B, in which is sedirection. The dash of the churn and the said ball are connected together by means of the rod D, which is clamped to the said dash by means of athumb-scre w, and passes through a slot cut in the said-ball.

It is obvious from the foregoing description that with each revolution of the balance-wheel a lateral as Well as a vertical motion will be imparted to the dash, and that the length of the stroke of the same may be accurately adj usted.

The balance-Wheel A has its bearings in the upright metallic standard E, which. is provided with an arm, E', through which passes the upper end of the dash-rod. To the said metallic standard E is attached, in such a manner as to be vertically adjustable, the clamping apparatus F, consisting oftheprouged arm f, hinged to the traveler f1 and the cam fl, by means of which the said arm' is held "firmly in contact with the top of the churn.

I am aware that churns have heretofore been invented and even patented (see the patents of William C. Douthell, May 12, 1868,

and October 13, 1868) in which a rotary movement ofthe reciprocating kdasher isproduced by means of double oscillating swing joints. I therefore do not claim the same generally 5 but- I claim, and desire to secure by Letters Patent- 1 The specic arrangement herein described of the wheel A provided with a lradial aperture, B, the adjustable box C, formed by the combination of the plates c c1 and thumbscrew c2, the:bal1 c3, rod D, when operating together as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this 6th day of February, 1871.

JOHN D. HARRISON. Witnesses:

CHARLES B. BARNETT, DANI.. BOWMAN.
