IMPROVEMENT IN RECIPROCATING CHURNS.

Specification forming part of Letters Patent No. 135,168, dated April 22, 1873; application filed December 7, 1 872.

To all whom it may concern:

Be it known that I, MAGNUS LITTY, of Williamsville, in the county of Richardson and State of Nebraska, have invented a new and valuable Improvement in Ghurns; and I do 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 drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a sectional view of my churn. Fig. 2 is a plan view of the same.

This invention has relation to churns and it consists in the construction and novel arran gement of the churn-frame, and the devices for imparting rotary motion to the dasher, as hereinafter described.

A in the drawing designates a table, supporting a cylindrical movable churn, B, having a vertical rotary dasher, G, with its upper bearing in a horizontal beam, D, and its lower bearing in the center of two connected intersecting bars, 0, which exactly fit within and upon the bottom of the cliurn,thereby centering the dasher-staff. The latter is designed to be removable, and for this purpose the beam D is provided with a mortise at one end, and a tenon at the other. The tenon passes through an aperture in an upright, E, while the mortise embraces a neck, 6, formed in'a corresponding upright, E. The mortise and tenon are long enough to allow the beam to be moved lengthwise suficiently to remove the tenon from its socket, so that the beam may be lifted for the removal of the dasherstaff. The lower shoulders at the sides of the neck 6 are beveled to allow the end of the beam the necessary tilt. The dasher has imparted to it a rotary reciprocating motion by means of a cord, H, wound around it, and connected at the ends to two posts, I, which are pivoted to the table and vibrated. in opposite directions alternately by hand. When the beam D is in its proper position it is there maintained by means of a wedge, H, driven into the mortise, as shown. The cords are attached to the posts or arms I by being passed into notches in the ends and knotted, as shown. A block, is, fixed uponthe table A, and constructed with a concave recess corresponding to the form of the churn, serves to steady the latter upon the table.

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

1. The notched vibratory alternating arms I with their lower ends pivoted to the table A, the rotary churn-dasher G, cord H connecting said arms and dasher, and the churn B, combined and arranged as specified and shown.

2. The Inortised and tenoned beam D,the upright E, the upright E having beveled notches, the wedge H, and the removable dasher 0, substantially as and for the purpose specified.

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

MAGNUS LITTY.
