SPECIFICATION forming part of Letters Patent No. 505,026, dated September 12, 1893.

Application led February 2| 1893. p Serial No. Ll=60,727. (No model.)

T0 all whom it may cor/werft:

Be it known that I, JOHN CoRwiN BUDD, a citizen ofthe United States, residing at Deiance, in the county of Defiance and State of Ohio, have invented anew and useful Improvement in Ohurns, of which the following is a specification.

The invention relates to improvements in churns.

The object of the present invention is to simplify and improve the construction of churns, and to enable them to be operated by a light power, and to produce butter rapidly.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure 1 is a perspective View of a churn constructed in accordance with this invention. Fig. 2 is a transverse sectional view. Fig. 3 is a longitudinal sectional view.

Like numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates a rectangular supporting frame consisting of corner posts 2 and 3, and top and bottom horizontal bars connecting the posts at their upper and lower ends. The frame supports at its front an oscillating churn body Il which is operated by ainotor 5 located at the back of the frame at the top thereof.

The churn body is substantially cylindrical, but may be of any other desirable coniiguration. It has a flat open top at which is arranged a bar or top piece 6, which has a slot 7 to receive an oscillating dasher 8. The stern of the dasher is arranged in the slot of the top piece 6 and is pivoted there to 5 and the churn body is provided at opposite sides of the top piece 6 with transparent cover plates 9, which permit the contents of the churn to be readily inspected.

Extending upward from opposite sides of the churn body are suspension bars 10, which are provided with series of perforations 11 adapted for the reception of a pivot rod 12, whereby the oscillating churn body is adjustably suspended in the frame. The pivot rod is provided at each end with spacing sleeves 13, interposed between the corner posts 3 and the suspension bars of the churn body to prevent the suspension bars slipping laterally on the pivot rod. Each of the corner posts 3 is provided with perforations 14 to facilitate the adjustment of the churn body.

The motor, which is operated by a spring, 15, has a pitrnan 16 which is connected with the suspension bars by a cross-rod 17, journaled in the top perforations ot the suspension bars and provided with a central opening to receive the front end of the pitman. The front end of the pitman is threaded to receive nuts 18, and spiral springs 19 are disposed on the pitrnan and interposed between the cross-rod and the nuts. The rear end of the pitlnan rod is connected to the wrist pin or a crank disk '2O of the motor, which instead ot being operated by a spring may be readily actuated by a weight. As the churn Ais oscillated the dasher is also oscillated within the churn body by means of a substantially stationary rod 21, which has its rear end secured to the frame of the motor, and its front end pivoted in a bifurcation of the upper end of the stem of the dasher. By this construction the contents of the churn body are thoroughly agitated and enables butter to be quickly produced.

It will be apparent that the churn is simple and comparatively inexpensive in construction, and it willbe noticed that the churn bodyitself serves as a regulator or governor as it is capable of vertical adjustment by means of the suspension or pendulum bars.

Changes in the form, proportion and the minordetails of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

1. In a churn, the combination of a supporting frame, an oscillating churn body provided with upward-extending suspension bars pivotally connected to the frame and extending above the pivotal point, a dasher arranged within the churn body and having a stem pivoted to the top thereof and projecting above the same, a motor having a pitman connected with the suspension bars above their TOO pivotal point and adapted to oseillate the churn body, and a stationary rod connected Wlth the stem of the dasher above the pivotal point of the same, substantially as described.

2. In a churn, the combination of a supporting frame, an oscillating churn body providedwith upward extending suspension bars, a cross-rod journaled in their upper ends and havlng an opening, a motor having a pitman arranged in the opening of the cross-rod and threaded thereat, nuts arranged on opposite sides of the cross-rod and screwed on the threaded portion of the pitman, and spiral springs disposed on the pitman and arranged between the nuts and tne cross-rod, substantialiy as described.

8..In a churn, the combination of a supporting frame, an oscillating churn body, the

suspension bars extending upward from opposite sides of the churn body and each provided With a series of perforations, a pivot rod arranged in perforations ot' the suspension bars, a cross-rod journaied in the upper ends of the suspension bars, a motor having a pitman connected with the cross-rod, an oseillating dasher mounted in the churn body and having a stem extending above the body,` and a stationary rod connected with the stem of the dasher, substantially as described.

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

JOHN CORWIN BUDD.
