JOHN PORTER KYTE, OF SALEM, INDIANA.

CHUBN.

SPECIFICATION forming part Of Letters Patent No. 506,404, dated October 10, 1893.

Application filed August 31, 1893- Serial No. 484,464. (No model.)

To aZZ whom it may concern:

l 3e it known that I, J OHN PORTER KYTE, a citizen of the United States, residing at Salem, in the county of Washington and State of Indiana, have invented certain new and useful Improvements in Ohurns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My Invention relates to an improvement in churns.

The invention willfirst be described in connection with the accompanying drawings, and then particularly pointed out in the claims.

In the drawings-Figure l is a longitudinal sectlon taken through the center of a churn embodying my improvement. Fig. 2 is a view 1n elevation showing the dasher. Fig. 3 1s an enlarged detail view illustrating the construction of the deflectors. Fig. 4 is a horlzontal section through the dasher paddles.

Referring to the drawings, 1 is a churntank, supported upon suitable legs, 2, as shown, and provided with a rounded bottom 3. Around the upper edge of the tank is socured a top frame 4, a pair of open bearings 5,be1ng formed in the upper edges of the top frame and churn-tank, one on each side, in which bearings is normally mounted a dashershaft 6 adapted to oscillate in the said bearings. To each end of the dasher-shaft is attached an arm 7, the outer ends of these arms belng connected by a handle-bar 8. A series of dasher paddles 9 are fixed to the under side of the dasher-shaft 6, these paddles being set at a slight angle to the axis of the shaft, and provided with a series of holes, as shown at 10. The lower parts of the paddles are connected by lateral extensions 11 while the upper parts are separated from each other.

To each end of the top frame is secured an end strip 12, each provided on its inner face with a deflecting surface 13, which is curved in a particular manner as will be more fully explained hereinafter. These deflector surfaces may be of metal, and bent to any desired shape and fastened to the under side of the end strips, or they may be formed by making the end strips of wood and curving the under surface to the shape required.

Moreover, the said strips are preferably removable, and for this purpose they are hinged at 14 and held into the churn tank by buttons 15, as will be fully understood from the drawings. To one of the end strips is hinged a lid 16 which shuts down between the arms of the dasher and rests on the top edge of the churn-tank which is recessed at 17 to receive it, in order that the top of the lid when closed may be flush with the top of the top frame.

The operation of my churn is as follows: The milk being placed within the tank, the dasher is lowered into the tank, with its dasher-shaft resting in the half bearings. The lid is then closed and the dasher oscillated by means of the handle bar. The action of the lower parts of the dasher paddles is to throw the milk against the deflecting surfaces at each end of the tank. These surfaces are curved in such a manner as to deflect the stream of milk toward the center of the tank, thereby throwing it against the upper parts of the paddles with considerable force and tending to break the milk globules whereby the butter is formed more rapidly than by the mere vibration of the paddles in the milk. The lower parts of the paddles being connected enables them to force a greater volume of milk against the deflectors with more force than if they were not so connected. As the end strips are hinged to the frame, they may be turned back to remove any butter which has formed beneath them, and for the purpose of cleaning the tank and deflector surfaces thoroughly.

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

1. In a churn, the combination, with a churn-tank, and an oscillating dasher mounted in the tank, of a hinged, concave-deflecting surface at each end of the tank,substantially as described and for the purpose set forth.

2. In a churn, the combination, with a churn-tank, and an oscillating dasher mounted in the tank, of a hinged, concave-deflecting surface at each end of the tank, said surfaces being arranged to deflect the milk toward the center of the tank and adapted to be turned outwardly in a reversed position,

substantially as described and for the purpose set forth.

3. In a churn, the combination, with a churn-tank, and an oscillating dasher shaft 5 mounted in the tank, of a series of dasher paddles fixed to the under side of the shaft,

said paddles being connected at their lower portions and separated at their upper portions, and a curved deflector surface hinged to to each end of the tank, each surface being arranged to deflect the milk against the upper separated portions of the paddles, substantially as described and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
