HARRY ABBOTT, OF NORTH HURON, NEWV YORK.

CHURN.

Specification of Letters Patent No. 28,723, dated June 19, 1860.

To all whom it may concern:

Be it known that I, HARRY ABBo'rr, of North Huron, in the county of Wayne and State of New York, have invented a new and Improved Churn; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, Figure 1 being a plan of the churn, with the cover removed; Fig. 2, a central longitudinal vertical section thereof.

Like letters designate corresponding parts in both figures.

The churn body A, is usually of rectangular form, and is supported by legs a, a, or in any convenient manner. Centrally, in the bottom of the churn body, is situated a cross-head B, the ends of which slide in vertical grooves b, b, or their equivalents, in the sides of the churn body. This crosshead is actuated through a connecting-rod C, by a lever D; said lever being jointed at one end to a vibrating fulcrum a, so as to allow the lower end of the connecting-rod to rise and fall vertically. Any equivalent means of actuating the cross-head may be employed.

To each side of the cross-head B, is hinged, as at (Z, (Z, a dasher E, the sides and ends f, 7', thereof, forming a frame, and having cross rods g, g, in the space thereby inclosed. The outer end of each dasher is inclined inward and upward, substantially as represented in Fig. 2; and has projecting bearings h, h, (shown in dotted lines,) which slide respectively in inclined grooves 2', i, or their equivalents, in the sides of the churn body. These grooves incline upward, as they extend inward, sufiiciently for the-bearings h, h, to work easily therein, as the inner ends of the dashers E, E, are raised and lowered, and to give a compound movement to the said dashers. The inclined grooves 2', 2', connect with the vertical grooves b, b, so that the dashers may be readily inserted or removed.

At a suitable position above each dasher E, is an auxiliary dasher G, hinged at its outer end to the end of the churn in any suitable manner so as to be easily removed; that represented in the drawings being by a staple in, passing over a hook Z, and retained thereon by a button m, fitting over it. The outer ends of the auxiliary dashers G, G, may most conveniently be hinged at a height corresponding with the center of the arcs their front ends describe as the dashers are raised and lowered, substantially as represented, so that there shall be as little friction at their inner ends, on the lower dashers, as possible. The auxiliary dashers have rods 0, 0, arranged longitudinally of the churn, and at right-angles to the rods 9, g, of the dashers E, E, below. The inner ends of the auxiliary dashers are connected with the inner ends of the dashers E, E, in any convenient manner, so that they will adapt themselves to the different positions required in churning. In the drawings, this connection is represented by the central rods 0, 0, of the auxiliary dashers, extending in ward beyond the ends a, n, and passing through staples p, p, in the dashers E, E.

Arranged thus, when the cross-head B, is lowered, the parts assume the position shown in black lines, in Fig. 2; and when said cross-head is raised, they assume the position shown in red lines, the inner ends of the dashers being raised, while the outer ends of the lower dashers E, E, are guided by the bearings h, h, thereof sliding in the inclined grooves i, Z. Arranged thus, the lower dashers E, E, have a compound motion; the inner ends being raised and lowered nearly vertically, while the outer ends are guided in and out nearly horizontally. The milk, or cream, passing through the rods g, g, of the dashers E, E, is violently and effectively agitated; while the rods 0, 0, of the auxiliary dashers, which have opposite and antagonistic motions, being arranged at right angles to the rods 9, g, eflectively break the currents, and allay the agitation on the surface, and thereby pre vent the milk or cream being dashed upward in the churn body.

\Vhat I claim as my invention and desire to secure by Letters Patent, is-

The combination and arrangement of the dashers E, E, guided in their motions by the vertical grooves 19, b, and inclined grooves 2', 2', or their equivalents, With the auxiliary,

counter-acting dashers G, G, constructed 5 and operating substantially as, and for the purposes herein specified.

In witness that the above is a true speci fication of my improved churn, I. hereunto set my hand this seventh day of April, 1860.

HARRY ABBOTT.
