To all 'whom t may concern:

Be it known thatI, EDWIN B. CLEMENT, of Barnet, in the county of Caledonia and State of Vermont, have invented a new and useful Improvement in Churns; and I do hereby declare that the following isa full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference made thereon.

The nature of my invention co-nsists in so constructing the dasher that when it is in operation, it will surround the cream and force it through spaces between the slats of the dasher by closing or folding together.

To enable others skilled in the art to make and use my invention, I will proceed to de The shape of my vessel, see Figure l, of the accompanying drawings, for holding the cream is described by the extremities of the dasher when being 7moved to the right and left until it is folded together, making the vessel a little larger each way so the dasher will not come in contact with it. The Sides of the vessel are perpendicular, the ends being circular to where the sides of the mouth of the vessel begin to flare out. A cover with two or more airholes, is litted to the mouth of the vessel.

A better understanding of the shape and form of the body of my churn will be gained by the description of the dasher as represented by F ig. 2. I use four pieces ofwood for arms, see letters B, B, B, B, exactly of a length and size. Near each end of each of these arms I bore a hole, see letters C, C, C, C, which holes are sufliciently large to receive the journals of the shafts D, D, and not swell and become tight when wet. There are four of these shafts, the length of each being equal and a. little less than the width of the vessel, with a journal or bearing on each end of each. Two of these shafts are not seen in the drawings. also use four connecting bars of equal length, see letters E, E, E, E,the ends of which bars are made fast at the shoulders of the journals of the shafts D D, see letters F, F. The under side of the two bottom connecting bars, I

make a little rounding corresponding with the bottom of the vessel.

The top of the dasher is a double door or lid, made of slats see letters G, G, G, G, one half inch thick, by one and one half or two inches wide, or any size necessary. These slats are made fast to wooden arms, which operate as hinges, one end of each, see letter H, others not seen, being connected by a screw or pin on which to turn on the insideof the connecting kbars near the shafts D, D. These doors orlids are secured in their place while churning,

slats like those represented by letters G, G,

, G, G, on the under side of the bottom convnectingbars See let-ters I, I, I, and on the outside edges of thearms B, B, B, B, see

letters L L L L L L leaving spaces of suitable width between them for the cream to pass through. In the center of two of the arms B, B, is a square hole, and in the other two a round one see letters J, J, J, one of the round holes not seen. A piece of metal withl a corresponding hole, is embedded in one side of each of these arms .see letters K, K, the opposite sides not seen.

The crank O, see Fig. 1, the shaft of which is square with the exception of the bearings on each end, is made to iit the square holes in the arms of t-he dasher, the

of the vessel, see Fig. l, letters M, M, the others not seen, and kept in its place `by the spring P, one end of which passes through the box M, see letter Q and into a groove cut in the bearing of the crank shaft. A round rod with a looped end see letter R, is put through the other box and through the round holes in the arms of the dasher. I cut a thread in one of these boxes, and a corresponding one on the rod, and this rod is screwed in and keeps its place. By working the crank forward and vback it will open and fold the dasher, and describe the inside of the vessel.

I come now to the operation. Place the 80 bearings resting 1n the boxes ineach side doors o1' lids down by the buttons. Put in That I claim as my invention and desire the rod and crank, with the handle of the to secure by Letters Pat-ent, `is
