PATENTED JAN. 6, 1903.






3g/70;? 551371115 af/bomma' 4 UNITED STATES PATENT OFFICE.



SPECIFICATION forming part of Letters Patent No. 717,531, dated January ,6, 1903. Application led April 9, 1902. Serial No. 1 l,986. (No model.)

To all whom. it may concern.-

Be it known that LGOMER G. BEYNoN,a citizen of the United States, residing at Des Moines,countyof Polk,a`nd State of Iowa, have invented a certain new and useful Improvement in Ohurns, of which the following is a specification.

My invention Vrelates tota new and useful improvement in chnrns, and has for its object to provide a churn which will be very simple in construction and can be manufactured at a comparatively small cost, but will be very efficient andV durable in action, and the churn is so constructedthat the dasher may be given either a vertical up-and-down movement or a rocking movement.

With these ends in view this invention cou sists in the details of construction and coinbination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specication, in which- Figure lis a vertical cross-sectional View of the churn; Fig. 2, a vertical section taken at right angles to Fig. l; Fig. 3, 4a plan View of the churn.

A represents the body of the churn. This body tapers upward, and the mouth or open end of the body is cylindrical in form, and upon the inside of the body near the upper end is formed an :interiorlyextending flange B, upon which is adapted to rest the coverO. This cover has formed through its center an opening D, through which the shank of the dasher is adapted to extend. Through the cover upon each side of the central opening D are formed the slots E, and in the upper face of the cover at right angles to the slots E and upon each side of the central opening D are formed radial grooves F. The dasher of the churn consists of the shank G, which has extending out from each side of the same the flat blades I-I, and extending through the shank and out from each side of the same is a pin I. This pin is placed in such a position upon the shank G that when the pin is caused to rest in the grooves F the bottom blade H of the dasher will be a slight distance above the bottom J of the body, and the grooves F are so arranged in the cover O that when the pin I is caused to rest in the grooves the blades I-I of the dasher extend across the body of the churn at its narrowest part, and then by oscillating the shank G the lfower end of the dasher carrying the blades will be caused to rock within the body A, and the churning may be accomplished in this manner. The bottom J is formed concentric with the pivotal point of the dasher, as shown in Fig. 2. The cover C is provided with notches K, which are adapted to register with projections L, extending inward from the upper rim of the bodyA. This will cause the cover to always assu me a position so that the grooves F will be in the proper position to hold the dasher, so that the bolts H will be at right angles to the greatest width of the body. When it is desired to do the churning by means of the usualvertical reciprocating motion, the shank'ofthedasher can be turned until the pins I register with the slots E, and then the `dasher may be reciprocated up and down in the usual manner, or when it is desi red to raise the cover O without disturbing the dasher or raising the same from the churn-body the shank G is turned until the pin I registers with the slots E, and then the cover maybe raised to inspect the contents of the churn without disturbing the dasher.

M is a cup secured to the cover O of the churn to prevent any of the contents of the churn from escaping, because of the fact that any milk or other substance working upward through the central opening or slots E will be prevented from spreading any further by the cupM and will ow back through the slots E or central opening D into the churn again.

Of course I do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is In a churn, a conical tapered body having an interiorly-extending liange and a concave bottom, a cover having a central aperture and a transverse recess in its upper surface formed at right angle to the aperture said cover be- IOO ing provided with transverse slots and adaptdasher-shaft and adapted to seat in the recess lo ed to seat on the anges of the body, projec- 0f the cover as and for the purpose described. tions extending inward from the upper rim of In testimony whereof I have hereunto afthe body, said projections registering in the fixed my signature in the presence of two subtransverse slots of the cover, a ring having a scribing Witnesses.
