CHURN.

SPECIFICATION formingpart of Letters Patent No. 657,805, dated September 11, 1900.

Application filed January 17, 1900. Serial No. 1,748. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES EMRY YATES, a citizen of the United States, residing near Mill Grove, in the county of Mercer and State of Missouri, have invented a new and Improved Operating Mechanism for Churn- Dashers, of which the following is afull, clear, and exact description.

My invention relates to mechanism for operating churn-dashers.

The object of my invention is to provide a comparatively simple and efficient mechanism of the above-indicated class which may be readily connected with and disconnected from the dasher of an ordinary churn and which may be operated uniformly with small expenditure of power.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the churn com'plete. Fig. 2 is an end elevation thereof. Fig. 3 is a side elevation with parts in section substantially on the line 3 3 of Fig. 2, and Fig. 4 is a sectional plan view on the line 4 4 of Fig. 3.

A is the churn-body, which may be of any suitable construction and rests upon the base B of the machine.

The cover 0 is preferably provided with a funnel D, surrounding the rod E of the dasher F and intended to prevent splashing of the milk. The dasher-rod E is provided at regular intervals with apertures E, adapted to be engaged by pins G, secured to a U-shaped cross-head G, which has sleeves G arranged to slide on a stationary vertical guide H, secured to the post I. The upper member of the cross-head G is provided with a horizontally-disposed loop G (see Figs. 1 and 4,) through which extends a pitman or connecting-rod J ,connected with the cross-head at J and operated by a crank K upon a shaft L, journaled in the post I. This shaft L carries a fly-wheel M and a pulley N, which is driven by means of a transmission-cord 0 from a large pulley P upon the actuating-shaft Q. This shaft is also journaled in the post I, and preferably the end of the shaft also has a bearing in the guide H, said guide having an upward extension or bracket H, in which is formed an additional bearing for the shaft L. The shaft Q is provided with a crank-handle R, so as to be adapted to be operated by hand. The post I is braced laterally by two inclined or diagonal stays S, extending from the bottom of the guide H to side extensions 1 of the post, and, furthermore, a rear brace T is provided, secured to the base B and to the post 1, preferably as shown in Fig. 2, by means of the same bolt U which also secures the stays S and the lower end of the guide H to the said post.

The machine is operated by turning the crank R, which causes the cross-head G, and with it the dasher F, to reciprocate up and down, churning the milk in the ordinary way. It will be observed that the dasher-rod is held very securely, since it is fastened to the crosshead G at two points of its length, and to absolutely prevent any possible disengagement of the dasher-rod from the cross-head a suitable pin V may be passed through apertures provided in the ends of the pins G. It will be understood that the said pins are passed through two of the. apertures E and that the distance between the dasher F and the cross-head G may be varied by engaging the pins G through appropriate apertures E, so that the machine may be used in connection with churn bodies of different sizes. The motion of the cross-head G also is very steady, owing to its being guided by two sleeves or slides G and owing to its being securely fastened to the dasher-rod. The employment of the fly-Wheel M and the particular bracing of the post I also contribute to render the motion steady and uniform.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In an operating mechanism for churns, the combination of the stationary guide, the cross-head mounted to move on said guide and provided with projections adapted to be connected to a dasher-rod and with a loop extending transversely in relation tothe guide, the pitinan connected with the cross-head and extending through said loop, and crank mechanism connected with the pitman.

2. In an operating mechanism for churns, the combination of the stationary guide, the cross-head having two spaced slides mounted to move on said guide and provided with two In testimony whereof I have signed 1113* projections adapted to be connected to a name to this specification in the presence of IO dasher-rod and with a loop extending trans two subscribing Witnesses.

and crank mechanism connected with the pit- J. M. PIERCE,
