S. MINER TILSON, OF ROOKLANE, INDIANA.
CHURN-DASHER.
SPECIFICATION forming part of Letters Patent No. 298,042, dated May 6, 1884.
Application filed September 12, 1883. (No model.)
To all whom it may concern:
Be it known that I, S. MINER TILSON, a citizen of the United States, residing at Rocklane, in the county of Johnson and State of Indiana, have invented a new and useful Churn- Dasher, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to dashers for churns, washing-machines, and the like; and its ob ject is to provide a dasher possessing superior advantages in point of simplicity, inexpensiveness, durability, ease of operation, and general efficiency.
In the drawings, Figure 1 is a side elevation of my improved dasher. Fig. 2 is a 1ongitudinal sectional view of the same. Fig. 3 is a bottom view thereof.
Referring to the drawings, A designates an air cell or chamber forming the bottom or dasher of the device, and comprising the top piece, B, and sides 0, preferably flaring, as
shown, the bottom of thechamber being open.
D is the dasher-staff, which consists of a tube, E, having its bottom end, F, open, and extending down through the top piece, B, to the plane of the bottom edge of the sides 0, while its top end, G, is open. This top end is closed by a cap-piece, H, as herein shown, and in said top is provided a valve, I. This valve preferably is formed by a plate, J, having a leather packing-disk, K, and secured in position by a flat spring, L, on the inside of the said top, the packing of the valve serving to normally close the opening M in top G.
The operation and advantages of my invention will be readily understood. On the downward stroke the air contained in the chamber A and in the tubular staff I) will be carried down to the bottom of the churn or vessel, as the valve willclose against its escape. On the succeeding upward stroke a vacuum is created at the bottom of the churn, and the valve opens by the atmospheric pressure outside and admits air to supply the vacuum. Thus air is forced through the fluid on both the downward and upward movement of the dasher, which in churning causes the oil and water to separate without friction to injure the grain of the butter, so that a better product is secured. The staff is secured to the bottom cell or chamber by transverse braces N N, arranged above and below the top piece, 13, the series above being at right angles to the series below for purposes of greater strength.
I am aware that churn-dashers have been heretofore constructed with a bottom cell, and
'with a tubular staff having its bottom end plane of the cell, transverse braces being provided above and below the top of the cell, and an auxiliary cap being fitted to the staff and provided with an improved spring-plate carrying a valve-piece, whereby superior strength of construction and convenience and efficiency in operation are secured.
I claim as my invention-- An improved churn-dasher, consisting of a bottom cell or chamber comprising the imperforate top and side walls, a tubular cylindrical stafi having the open top and bottom ends, the latter end extending down through the top of said chamber to the plane of the bottom edge of the side walls thereof, the transverse braces disposed above and below the top wall at the point of juncture of the said. top wall and staff, and the top cap-piece fitted to the top end of the tubular staff, and having the fiat spring carrying a valve at its free end, substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my own, I have hereto affixed my signature in presence of two witnesses.
S. MINER TILSON.
