IMPROVEMENT IN CHURNS.

Specification formingpart of Letters Patent No. 160,] 39, dated February 23, 1875; application led May 16, 1874.

To all Iwhom it may concern:

Be it known that I, DAVID O. BAILEY, of South Salem, in the county of Rossand State of Ohio, -have invented a new and valuable Improvement in Churns; and Ido hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specication, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a sectional view of my churn.

This invention has relation to churns having dashers which revolve in opposite directions to each other; and it consists in two shafts having metal tips, and one revolving within the other, and carrying dash-blades, in combination with bevel-wheels on said shafts, which engage with a master-wheel having its bearing on a shaft which is secured to a frame on the churn-box cover, as will be hereinafter explained.

In the annexed drawings, A designates a churn-box of rectangular form, and B B are the covers thereof, one of which is secured by a button, e, and the other is firmly held down in its place by means of screw-clamps b b. On the cover B is secured a frame, (l, which affords bearings for the upper section D1 of a dasher-shaft, D, and for a beveled masterwheel, H, on the hub of which is a hand-crank, J. The upper section D1 turns in bearings c c, and carries on its upper end a bevel spurwheel, G, which engages with the teeth ofthe master-wheel H. The lower end of the section D1 is square, and is removably fitted into a socket, a, on the upper end of the shaft-section D. This socket a is an enlargement of the inner shaft D, and its shoulder a rests upon a metal bearing, z, which is let into a recess in the upper end of the outer shaft D2. By this means the squared end of the shaft D1 may be made sufficiently large to secure the requisite strength. The shaftsection D is supported in a step, d, on the bottom of the churn-box, and has secured to it a hub, E', carrying dash-blades F. D2 designates a hollow shaft, the lower end of which is tipped with metal, as indicated at z', which tip bears on a similar tip, j, on the upper end of the hub E. This hollow shaft is provided with a hub, E, to which dasher-blades F are secured, having the same shape as the blades on the hub E. Shaft D2 receives through it the rod D, and on its upper end a bevel spur-wheel, G', is keyed, which engages with the masterwheel H, below the center of this wheel.

From the above description it will be seen that when the wheel H is rotated it will communicate rotary motion in opposite directions to the two shafts D D2, thereby causing the blades F to produce counter currents of the milk in the box A.

What I claim as new, and desire to secure by Letters Patent, is

The shafts D D1, in combination with the enlarged socket a, having a shoulder, a', and the metallic bearing z, let into the upper end of the shaft D2, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

DAVID GORE BAILEY. Witnesses:

WILLIAM F. BAILEY, WM. T. NEIL.
