OPERATING MECHANISIVI FOR CHUR/NS.

'Specification of Letters Patent.

Patented Jan., 9, 1931*?.

Application filed January 21, 1914. Serial No. 813,470.

To all whom t may concern:

Beit known that 1, RUrUs H. Woon, a citizen of the United States, residing at Overton, in the county of Dawson, State of Nebraska, have invented certain new and useful Improvements in Operating Mechanism for Ghurns; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same.

r1`his invention relates to new and useful improvements in churns and particularly that type wherein the dasher is given a vibratory motion.

The object of the present invention resides in the provision of a churn wherein the dasher actuating means may be readily disassociated with the dasher and so positioned that access may easily be had to the interior of the churn. l

A. further object of the invention resides in the provision of a churn of the class described which comprises a minimum number of parts so that it is durable and eicient in use and may be manufactured at a comparatively low cost.

`With these and other objects in view, the invention resides in the novel combination, formation and arrangement of parts to be more fully hereinafter described and particularly pointed out in the claim hereto appended and illustrated in the accompanying drawings. j

Reference is had to the accompanying drawings wherein similar characters of reference designate corresponding parts through the several views, and in which:

Figure 1 is a side elevational View of the improved churn, Fig. 2 is a top plan view thereof, Fig. 3 is an end view of the churn, Fig. et is a sectional view on the line l-- of Fig. 1, Fig. 5 is a sectional view on the line 5 5 of Fig. 2, and Fig. 6 is a perspective view of the dasher arm.

Referring now more particularly to the accompanying drawings, 5 designates the base of the churn on which the drive shafts are positioned. This base portion 5 is separated from a base portion 6 by a partition wall 7. Seated on the base portion 6 and held against displacement longitudinally by the cleats 8 is a churn receptacle 9 having a detachable cover 10 through which extends the shaft 11 of the churn dasher.

Journaled in suitable bearings on the base 5 is a shaft 12 extended at one end past the base and carrying a crank handle 13. The other end of the shaft has xed thereon a beveled gear 14 which meshes with a relatively smaller gear 15 at the lower end of the vertical shaft 16 which is journaled in suitable brackets 17 carried by an upright 13 on the base. Fixed on the shaft 16 above the upright is a fly wheel 19 whereby a steady operation of the churn is insured. The top of the shaft 16 carries a plate 20 on which is positioned a bar 21 extending at one end past the plate. A sleeve 21 having annular end ribs 22 is positioned on the extended end of the bar and held in place by a bolt 23 passed therethrough and through the bar.

The means whereby rotary motion of the vertical shaft 16 will impart oscillatory motion of the dasher shaft 11 includes an arm 2e, fixed to the upper end of the dasher shaft and having its free portion upwardly offset and bifurcated as at 25. rIhe base portion 6 carries an end wall 26 and positioned on this wall is a block 27 provided with a socket 23 in which seats a pintle 29 carried by the bight portion of a U-shaped member 30. Pivoted between the arms of this AU- shaped member is one end of a link 31 which has its other end disposed adjacent the olfset portion of the arm 24. A. roller 32 depends from the end of the link 31 and is disposed between the furcations of the arm 24. Connecting the link 31 and the sleeve 21 is a link 33 having one end pivotally receiving the sleeve and having its other end provided with the furcations 34 which embrace the link 31 adjacent a series of openings 35 formed therein, a bolt 36 being pivotally passed through the furcations and through one of the openings whereby an adjustable pivotal connection of the link is procured, to render adjustable the movements of the link 31 with relation to the movement of the link 33.

From the foregoing it is observed that a simple and efficient churn has been provided wherein the churn dasher may be readily and quickly removed when desired.

What is claimed is:

A churning mechanism from which a churn body and dasher may be quickly released for removal, consisting of a body supporting base provided with an upright,

a lever connected with the upright for pivand from which connection it is disengageotal movement both parallel with the base able when moved away from the base.
