CHURN.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed May 15, 1908. Serial N 0. 433,003.

To all whom it may concern:

Be it known that I, DOLE HAMILTON, a citizen of the United States, residing at Goshen, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Churns, of which the following is a specification, reference being had therein to the accompanying drawing.

My present invention relates to improvements in churns, and has special reference to a new and improved construction of churn receptacle, dasher, operating mechan ism, and means for connecting the dasher and operating mechanism.

To more clearly illustrate my invention, attention is invited to the accompanying drawings, in which Figure l is a perspective view of my churn. Fig. 2 is a vertical central section thereof. Fig. 3 is a cross section through the churn. Fig. 4 is a detail of the dasher, and Figs. 5 and 6 are details of the connection between the dasher and operating mechanism.

Referring to-the drawings :The numeral 1 designates the churn receptacle, which is preferably made to taper outwardly from its top to its bottom, the receptacle in cross section being substantially rectangular in shape, except for the curved corners or sections 2, the bottom 3, being the same shape as the receptacle. Mounted upon the receptacle eXteriorly are the hoops or bands 4, 5 and 6.

The upper hoop or band 6, carries the three eyed lugs 7, which are each provided with the set screw 8, by means of which the tripod or operating mechanism supporting frame 9 is supported. By this means the operating mechanism is carried removably from the receptacle, and yet while in use or attached, allows free access to the receptacle from the side 10, of the same, the tripod supporting the same far enough above the receptacle to allow the proper leverage upon the operating handle 11.

Secured to the upper portion of the tripod, is the base 12, of the casting 13, which has the bearing 14, for the horizontal shaft 15, which carries the large spur gear 16, and its handle 11. In the forward portion near the base of the casing is a recess or slot 16, in which is mounted the small spur gear 17, which meshes with the gear 16, its shaft 18, being journaled in the socket 19 and the bearing 20, of the castin Upon the lower end of the shaft 18, I provide the shoulder 21, while slidingly mounted upon this end, and held in its proper adjustment therein by means of the spring 22, is a looking or retaining ring or sleeve 23, which is adapted to surround the upper shouldered end 24 of the dasher shaft 25, and hold the two shafts coupled. Thus it will be seen that by operating the large gear 16, the shaft 18 and the dasher shaft are revolved.

The lower end 26, of the dasher shaft is enlarged and provided with a series of obliquely arranged openings 27, in which I mount the cylindrical dashers 28, which as shown extend upon opposite sides of the dasher in obliquely stepped order, this positioning being of great importance, as each dasher operates upon the same strata of cream upon opposite sides simultaneously, and has a more even whipping action thereon. In the lower end of the dasher shaft I provide the conical recess 29, for the reception of the cone 30, mounted in the bottom of the receptacle, so as to assist in holding the dasher shaft properly journaled' and centered Within the receptacle.

What I claim, as new is In a churn, the combination with a four sided receptacle, of a dasher having a shouldered upper end, a tripod mounted removably to three sides of the receptacle and above the same, a vertical shaft having a shouldered portion adapted to co-act with the shoulder of the dasher, said shaft passing through the tripod, a sleeve slidingly mounted to sur round the co-acting ends of the dasher and shaft to makea detachable coupling therebetween, means to hold the sleeve in operative or inoperative position, a pinion carried by the shaft above the tripod, an angle casting secured to the center leg of the tripod and said gear Wheel and above the free side of having bearings for the vertical shaft and a the receptacle. 1: recess between the bearings for the passage In testimony whereof I aflix my signature of the pinion, said casting also being proin presence of two Witnesses.

Vided with a horizontal bearing in its upper DGLE HAMILTON.
