IMPROVEMENT IN CHURNS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern:

Be it known that I, JOHN A. GOZAD, of Mercer, in the countyof Mercer, and State of Pennsylvania, have invented a new and useful Improvement in Churns; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to accompanying drawings, in which- Figure 1 is a plan view, without the lid;

Figure 2, a side elevation; and

Figures 3 and 4, details.

Like letters designate like parts in all the figures.

The nature of my invention consists in the peculiar construction and arrangement of mechanism by means of which the dashers are held in their place, or by its operation rendering their removal an easy matter.

To enable those skilled in the art to lmake and use my invention, I will proceed to describe its construction and operation.

In the drawing- A represents the churn. I

v B B, the shafts, in which are blades C, thus forming the dashers.

Thse blades are placed at right angles to each other on each shaft, but are arranged obliquely to the sides of the churn, as seen in fig. 1, and any desired number may be used.

In these blades are holes, as in ordinary dashers.

To one side of the churn is secured a fraaie, D D',

and between it and the churn, splaced the driving' mechanism, which consists of a large gear-wheel, E, and two pinions, F F.

Outside of the frame, on the shaft of the gear-wheel E, is a crank, G.

In the ends of the shafts B are recesses, the inner ends of the shafts a a of the pinions F F tting into those in the ends of the shafts B next to them and in the other side of the churn are pivots b b, which t into the recesses in the other end ofthe shaft B.

On the shafts a a are shoulders c c, the portion of the shafts outside of these shoulders being smaller than the diameter of the said shoulders.

The outer ends of these shafts rest in the horizontal portion-D of the ame, leaving a space between the the shafts a a, between the shoulders c cand the horil zontal part D of the frame; the pin beingr in the extreme upper portion of the slot h, and that 'portion being at or about' right angles to the sides of the.

forked ends of the bars e c, the said bars are here held rmly on the shafts aa.

When it is desired to remove the dashers, move the bars e e horizontally on the pins d, until the ,verti-v cal part of the slot is under the pins d, then raise the bars e e, which leave the space open between the shoulders c c and the frame D.

The shaft a and its Vpinions can then be drawn out towards the frame D, thereby removing the inner end of the shafta fromv the socket or recess inA the end of the shaft of the dasher, thus releasing it so that it can be renovedfor cleansing or other purposes.

I am aware that both straight and curved slotted bars have been used to hold the dasher-shafts in place while in use, but they are not self-locking de# vices.

lWhat I claim as new, and desire to secure by Letters Patent, is-

`The angular self-locking slotted bars e e, in combination with the frame D D' and shafts Ao a, when constructed and operated substantially as shown and described.
