IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 217,065, dated July 1, 1879; application filed April 1, 1879.

\ To all whom it may concern Be it known that I, JOHN OocHRAN, J r., of Lebeck, in the county of Cedar and State of Missouri, have invented certain new and useful Improvements in Ohurns; 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, and to theletters of reference marked thereon,which form a part of this specification.

My invention relates to that class of churns in which two dashers are so arranged on separate shafts as to be rotated in opposite direc tions by suitable connection with bevel-gears; and it consists in the construction and combi nation of certain parts, as will be hereinafter described, and set forth in the claims.

In the annexed drawings, which fully illustrate my invention, Figure 1 is a central ver tical section of a churn embodying my invention. Fig. 2 is a similar view, taken on the line a; as, Fig. 1; and Fig. 3 is a plan view of the slide L.

A represents the'ohurn-lid, on top of which is a housing, B, for containing the operating mechanism. This housing is made in two parts, which are fastened to the lid an d to each other by screws, bolts, or otherconvenient means. 0 is the horizontal shaft, provided at its outer end with a crank, E, and at itsinner end with a bevel-gear wheel, D, for operating the two sets of dashers.

G and G are the two sets of dashers. The dashers G are attached to the lower end of a sleeve, F, which passes through the lid A and into the housing B, and within the housing said shaft is provided with a bevel-gear wheel, H, which meshes with the gear-wheel D at the bottom. The dashers G are attached to the lower end of a shaft, I, which passes through the The bevel-gear J has bearings at b b in the housin g, which prevent any up-and'down movement of said gear; but the shaft I has a limited up-and-down movement or adjustment by means of a wed ge-slide, L, passing through one side of the housing, and having a slot for the passage of the shaft. The shaft has two cir cumferential collars, cl d, between which the slide L passes, and on the bottom of the lower collar is a clutch, c, to engage with a corresponding clutch on the upper end of the sleeve F.

WVhen the slide L is pushed in, the shaft 1 is raised far enough, to cause it to engage with the bevel-gear J by means of the clutch a, while the clutch c is disengaged, and when in this position the dashers are rotated in opposite directions. When, however, the slide L is drawn outward, its wedge or inclined portion is retracted from under the collar cl on shaft or rod I, and hence the said shaft drops down until its upper clutch, a, is entirely disconnected from the gear-wheel J and its lower clutch, a, connected with a clutch, f, upon the sleeve or hollow shaft F of the lower gearwheel, H. In this position the upper gearwheel, while free to revolve, has no connection whatever with the shaft or rod I. This shaft being, however, now connected with sleeve F by the clutch, as above stated, both dashers will be adapted to rotate together and in the same direction. pushed in, its inclined surface acts against collar d, and thereby raises shaft I until its lower clutch is freed from the clutch on shaft F and its upper clutch brought into engagement with a suitable groove or notches formed in the under side of the small upper gearwheel. In this position the two shafts F and I will be rotated in reverse directions when the crank-handle, horizontal shaft, and gearwheels transmit motion thereto. 1

The dashers are constructed of vertical bars G and G, fastened to the ends of crossbars at their upper ends, and these cross-bars are fastened, respectively, to the lower ends of the sleeve and shaft.

The vertical bars or paddles of the dashers are made T-shaped in their cross-section,which gives a flange on each side along the outer edge of the paddle to hold the milk to its When the wedge or slide is proper place and to prevent the cream from leaving the center of the churn.

In the lidA is a hinged door, M, and a slide, N, the former to see how the churning is progressing, and the latter to uncover a vent for the escape of air. The lid is fastened by two hooked projections, O, and a cam, P, to any suitable churn-body.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Ina churn having two sets of dashers operated in opposite directions by means of the bevel-gears D H J, as described, the movwedge-slide L, sleeve F, and bevel-gear J, substantially as and for the purposes herein set forth.

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