MACHINE FOR OPERATING CHURNS1 rSPECIIFICATIN forming part of Letters Patent No. 223,258, dated January 6, 1880.

Application led December 1, 1879.

To all whom it may concern Be it known that I, LEONARD G. SWEET, of Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Machines for Operating Chnrns; 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 appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure l is a perspective view. Fig. 2 is a vertical sectional view taken longitudinally through the crankshaft, and Fig. 3 is a vertical sectional view of Fig. 2.

Corresponding; parts in the several figures are denoted by like letters of reference.

This invention relates to an improved machine for operating that class of churns which are provided with vertically reciprocatimgr dashers; an d it consists in the construction and arrangement of the parts constituting the same, which will be hereinafter fully described, and particularly pointed out in the claim.

In the annexed drawings, A :represents a base provided with three uprigl1ts,B B O, the two former of which are provided with brackets D D, extending in a direct-ion opposite to the upright O. The brackets D D are connected by a cross-piece, E, supporting a fourth upright, F, the top of which is connected with the upper ends of the remaining uprights by a cross-brace, G.

The uprights B B are provided with boxes or bearings for acrank-shaft,-H, provided with balancewheels l l, disposed one on each side of the crank. Upon the crank J of shaft H is adjusted a box, K, sliding in a horizontal slot, L, in a cross-head, M, adapted to slide vertically between the uprights C F, which are provided with suitable slots N, to receive the ends of said cross-head. The lower side of the cross-head M is provided with a stud, O, having an opening, P, to receive the upper end of the dasher-staii.

Q is a bail, pivoted in the sides of the stud O so as to swing downward and enter a notch, R, out in the side of the dasher-staff near its upper end, and thus attaching it securely to the cross-head.

The churn S is secured upon the base between the uprigh ts B B C by means of cleats T.

The crankshaft H may be operated by a hand-crank, U, or in any other suitable manner.

The operation of my invention will be readily understood from the foregoing` description, taken in connection with the annexed drawings. It is simple,inexpensive, durable, and may be advantageously used to operate any churns of the wellknown old-fashioned construction.

Having thus described myinvention, I claim and desire to secure by Letters Patent of the United States- As an improvement inchnrn-opera ting mechanisms, the frame A B B O D D E F Gr, Crankshaft H, having slide-box K, and the crosshead M, having slot L, and recessed stud O, having pivoted bail Q, all constructed, arranged, and operating as described,in combination with a dasherstai' having notch R, substan tially as and for the purpose set forth.

ln testimony that I claim the foregoing as my own l have hereto affixed my signature in presence of two witnesses.'

LEONARD G. SWEET.
