JOHN R. IIALLEY, OF NASHVILLE, IOWA.

CHURN.

SJPECIFICATION forming part of Letters IEatent No. 599,332, dated February 22, 1898.

Application filed January 4, 1897.

To all whom it may concern:

Be it known that I, JOHN R. HALLEY, of Nashville, Jackson county, Iowa, have invented certain Improvements in Churn-Paddles, of which the following is a specification.

My invention relates to improvements in that class of churns in which the churn-body and the paddle or agitator revolve in opposite directions; and it consists more particularly in an improved form of fastening for the paddle-shaft.

My invention further consists in the specific features of construction hereinafter particularly described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view of a churn embodying my invention, partially broken away to show the interior construction. Fig. 2 is a partial vertical cross-section of the barrel and the contained paddle. Fig. 3 is a detail view of the bearing-block for one end of the paddle-shaft, and Figs. 4 and 5 are details of my improved fastening for the opposite end of the paddleshaft.

In the drawings, A represents the churnframe, of any suitable construction, and, as shown, comprising the base 2 and parallel upright standards 3.

B is the churn body or barrel, having journal support in the frame A by means of the gudgeons 4, turning in the tops of the standards 3, one of the gudgeons being provided with ahandle 5, by means of which the churn may be rotated.

O is the agitator or paddle, arranged within the churn, as shown in .Fig. 1. The paddle is formed with radiating wings 6, centrally cutaway, as shown. The paddles are secured in the churn by means of the fastenings illustrated in Figs. 3 to 5. A block 7 is secured to the inner side of the churn-body by means of screws 8 and is formed with a central opening 9, serving as a bearing for one end of the paddle-shaft. To the opposite side wall of the churn is secured a similar block 10, provided with my improved form of fastening. This consists of a spring D, arranged in a groove 11 in the top of the block and secured thereto by means of screws 12,passing through the eyes 13. The spring is shaped so as to form a bearing portion 14; and a stirrup por- Serlal No. 617,883. (No model.)

tion 15 at the top, with an intermediate contracted neck 16. Thus in placing the paddles in the churn one end of the paddle-shaft is placed in the opening 9 in the block 7, with the opposite end resting in the stirrup 15 of the spring D. By then pressing the paddle down the spring will be forced open, allowing the end of the shaft to pass below the neck 16, as shown in Fig. I. The top of the block is formed with a circular socket 17, in which the rod will rest when in place. The paddle may be. easily removed by lifting upon the end next the spring-fastening with sufficient force to open the spring.

As will be seen, in my improved form of fastening there are no parts to get out of order and the paddle is much more easily inserted and removed than with the form of fastening where there are any parts to be moved.

WVhile I have shown my invention applied to a barrel churn, it will be evident that the same idea may be embodied in a revolvingboX churn. In both constructions of churn the paddles are centrally cut away, as shown. With a solid paddle the milk striking against the center would be likely to throw the paddle out of its fastenings.

I claim- 1. In a churn, the combination with its rotary paddle, of the bearing-block adapted to receive one journal of the paddle-shaft, the open-top bearing-block for the other journal, and the two-part spring-clasp for holding said journal upon said block, the members of said clasp being brought toward each other above said journal, and then spread apart in V shaped position, whereby the journal may be inserted by merely pressing the same down between said members, or removed from said block by lifting it upward.

2. In a churn, the combination with the rotary paddle and its shaft, of the bearing-block adapted to receive one journal of the paddleshaft, the open-top bearing-block for the other journal, and the spring secured in said block, and serving as a bearing for the end of the paddle shaft, and constructed above said shaft to hold the same in place, but adapted to be opened to release the shaft by means of pressure exerted against the paddle.

3. In a churn of the class described, the

combination with the rotary paddle and its pressure exerted against the tension of the shaft, of a suitable bearing for one end of the spring. 10 shaft, the bearing-block for the other end, In testimony whereof I affix my signature and the spring-clasp for receiving the shaft, in presence of two Witnesses.
