Specification of Letters Patent.

Patented June 9, 1908.

Applicatition filed June 1, 1907. Serial No. 376,758.

To all whom it may concern:

Be it known that I, OSCAR J. NEAL, a citizen of the United States, residing at Colfax, in the county of WVhitman and State of Washington, have invented a new and useful Churn, of which the following is a specification.

This invention relates to a churn of that type in which a rotatable shaft operates a vertically movable dasher and at the same time rocks the churn body.

The object of the invention therefore is to simplify the construction, make positive the several movements of the parts, and produce butter in a rapid manner.

In the accompanying drawingsz-Figure 1 is a plan view of the improved churn. Fig. 2 is an elevation of the same. Fig. 3 is a ver tical sectional view on the line 33 of Fig. 2.

Similar numerals indicate the same parts in all the figures.

Upon a suitable base 1 formed of longitudinal bars 2 and cross bars 3 rise two up rights or standards 4, 4, joined together at the top by a cross brace rod 5. The standards 4 are seated or otherwise connected to the longitudinal bars 2 at the bottom, and braced on each side by struts 6.

A churn body indicated by the numeral 7 and represented as of cylindrical form, is pivoted near its bottom and at opposite sides on pins 8, projecting inwardly, from the standards 4 and seated in depressions in the body in a manner well understood. On the outer side of each standard is fastened a socket, through which sockets the pins 8 pass and are held fixed by small pins extending through the sockets to the pins 8. The latter pins 8, it will be noted, must have a longitudinal movement to permit the mounting of the receptacle on the pins and its removal therefrom. A cover 9 is provided for the churn, the body of which enters the mouth of the churn and is supported by a horizontal flange 1O resting on the top of the churn as shown. Lugs 11 project from the flange 10 through which bolts 12 pass to receive thumb nuts 13 for fastening the cover to the churn. The churn dasher 14 within the churn is secured to one end of a dasher rod 15 passing out through a hole in the cover 9 and has on its outer end a cap bearing'16.

Mounted in bearings in the standards 4 above the churn 7 is a horizontal shaft 17 one end of which carries a balance Wheel 18, the other end an operating handle 19 while intermediate the standards is a crank 20.

Projecting from one side of the churn at a right angle to the shaft' 17 is a bracket 21 rising above the churn to a point substantially in line with the horizontal shaft 17 where it is forked as at 22. To the crank 20 is connected the dasher rod 15, and one end of a connecting rod 23, its other end having pivotal connection with the fork on the bracket 21 attached to the churn.

In the operation of the invention, after a suflicient quantity of cream has been poured into the churn, the dasher is placed therein and the cover fastened on by the thumb nuts. Now, on rotating the shaft 17, the crank 20 revolves, raising and depressing the churn dasher in the usual manner. At the same time the crank tends to move the connecting rod crosswise of the direction of movement of the churn dasher, and as the connecting rod is pivoted to the bracket 21 of the churn, which is itself mounted on journals, the churn will reciprocate back and forth with every rotation of the crank shaft. These two movements combined, that is to say, the movement of the dasher in one direction and the churn in a crosswise .direction, rapidly separate the butter particles from the buttermilk.

Having thus described the invention what is claimed is A churn comprising a supporting frame having two spaced uprights, a socket fastened to each upright near its lower end, a slidable pivot pin extending through each socket and upright and having means on said sockets for fastening the pins in fixed position, a receptacle pivoted directly on said pins at diametrically opposite points and close to its bottom, an upright arm fixed to one side of the churn in a plane at a right angle to the plane passing through said pivot pins, a horizontal shaft journaled in said uprights parallel to the axes of the pivot pins and above said receptacle, said shaft having In testimony that I claim the foregoing as a crank intermediate'said uprights, a churn my own, I have hereto afiixed my signature 10 dasher pivotalgly connegted to said11 crank, a in the presence'oftwo Witnesses.

connecting ro pivote at its en s respectively to the crank and to said upright arm, OSCAR NEAL and means for rotating said crank shaft to Witnesses:

simultaneously operate the churn dasher and M. PICKRELL,

rock the receptacle on its pivot pins. WILL R. HEGLAR.
