CHURN.

SPECIFICATION forming part of Letters Patent No.. 296,202, dated April 1, 1884.

Application filed February 18, 185:2. Renewed February 5, 1834. (No model.)

To all whom it 12ml; concern.-

Be it known that 1, Mac N. MCKINNEY, of Jackson, in the county of Hinds and State of 1 Mississippi, have invented certain new and useful Improvements in Chorus; and I do hereby declare that the following is a full, clear, and exact description of the invention,

which will enable others skilled in the art to which it appcrtains to make and use the same,

reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a side elevation of my improved churn power and dashcr. Fig. 2 is a perspective view of a portion of the top part of the frame, one of its side pieces having been removed to show the double crank and its belts.

Fig. 3 is a sectional view through the double crank and the buckled endof one of the belts attached to it. Fig. 4; is a transverse vertical section through the pulley-box, pulley, and coupling-sleeve; and Fig. 5 is a perspective view of the lower part of the dasher-staff and composed of two parallel side pieces, G 0,

connected at their outer end by parallel crosspieces D D, said frame, it will be seen, forming an arm of suitable length extending from the top of post B parallel to the platform or bed-piece A. In each of the side pieces 0 is a box or hearing, D, for the ends of the double crank E E. These boxes slide in slotted ways 0 c in the sides 0, in which they may be properly adjusted by binding-screws d d to regulate their distance from the outer end of the arm or frame. The sliding bones having been properly adjusted in their ways to take up slack of the belts, they are fixed in their places by screwing up the binding-screws d (1 until their heads press or bind against the sides of the ways 0 c across the slot formed by I said ways; as shown in Fig. l of the drawings-that is to say; the ways 0 being slightly dovetailed in cross-section, and the sliding boxes I) being similarly dovetailed, the tightening of the screws ('6 (1, so as to bring their heads transversely across the ways, will operate to wedge the boxes firmly in their ways. lhe double crank E E has a crank and handle, E, for rotating it.

F and F are belts or hands, of leather or other suitable material, which are buckled at f and f, respectively, around metallic sleeves or collars c e, placed upon the cranks to prevent wearing of the belts. By shifting the position of the buckles f and f the bands may be tightened to take up slack when required, which may also be effected by moving the boxes D in their slotted ways c.

The dasher-staff (shown at G) is inserted into a sleeve or thimble, II, at the lower end of the pulley-shaft I, and held therein removably by the set-screw i. p

K is the pulley or drum, which is j ournaled between the parallel end pieces, D D, as shown in Fig. 4., and has secured to it the ends of the belts F and F, which are wound around it in opposite directions. By turning crank E a rotary reciprocating motion is imparted to the pulley K and dasher-staff G by nieansof the belts F and F, and this without the jerky motion which results from the employment of the usual crank -and -pitman mechanism. The lower part of the dasherhas a cross-head, h, at its lower end, from which two arms, A", project upward on opposite sides of the staff, parallel to each other. These arms increase in width toward the top, where they are out off slantingly, as shown at 7; and (see Fig. 5,) the slants or inclines being in opposite directions. It will also be seen that the cross-head I is beveled on both sides of the central tapering staff, G, as shown at the rounded parts h audit, forming a sharp ridge on each side. By this construction of the dasher and its staff a downward draft will be created in the center of the churn and an upward draft or current along its sides, caused by the beveled side wings or arms, k k and k is, thus causing a thorough agitation of the cream and commingling of the butter globules. This shape of the dasher also admits of the staff G is cut off tapering, as shown at g, and

ready removal of the butter when inade,without the necessity of removing the dasher from the churn.

I am aware that it is not new to operate a churn dasher by means of belts or bands wound around apulley at the head of the staff or around the staff itself, nor do I lay any claim to this construction and arrangement,

broadly; but,

Having thus described my improvement, I claim and desire to secure by Letters Patent of the United States 'Ihe dasher composed of the staff G, cut away or tapered on opposite sides, g, at its Witnesses:
