CHURN DASHER.

THOMAS G. WADE, 0F BEARD, NORTH CAROLINA.
CHURN-DASHER.
Specification of Letters Patent.
Patented July 24h, 191%.
Application filed December 29, 1916. Serial No. 139,491.
To all whom it may concern:
Be it known that I, THOMAS G. WADE, a citizen of the United States of America, and a resident of Beard, county of Cumberland, State of North Carolina, have invented certain new and useful Improvements in Churn-Dashers, of which the following is a full and clear specification.
This invention has relation to that type of churn dasher which is reciprocated, usually manually, in the body of milk, to thereby thoroughly agitate the same, and the object of this invention is to so construct the dasher that the churning operation is greatly expedited without appreciably increasing the labor and also without appreciably increasing the expense of manufacturing the dasher, as more fully hereinafter set forth.
In the drawing Figure l is a bottom view of my improved dasher, the head of the ournal pin or screw being shown in section;
Fig. 2 is a side elevation of the same; and
Figs. 3 and 4t are transverse sectional views on the lines, respectively, 3-3 and H of Fig. 1.
Into the lower end of the usual staff a is inserted a headed journal pin 6 which is preferably in the form of a screw. Between the head of this pin and the end of the staff, I journal a pair of dasher members which are exactly alike and each of which is substantially in the form of a propeller, the two propeller members being separated from each other by a loose anti-friction washer 0.
Each propeller is constructed of a hub, through which the pin 5 extends, and four radial blades, two of the opposite blades (Z being true propeller blades, the cross-section of which is shown in Fig. 4:, and the other two 6 of which are beveled only on their under sides, one edge f being vertical or approximately vertical and the top surface being practically flat.
In mounting these propellers on the staif they are arranged so that their flat faces 9 face away from each other, one upwardly and the other downwardly. In operation, the quick upward movement of the dasher through the milk serves to rotate quite rapidly the lower propeller, since all the inclined sides of the blades of the lower propeller are faced upwardly. In performing this upward movement, the upper propeller stands practically stationary, it being held in this position not only by reason of the fact that the upper fiat sides 7 tend to resist the rotative tendency naturally given to the propeller by the upper surfaces of the inclined blades (Z, but also because of the fact that the fiat vertical edges f of the lower propeller serve to throw the milk violently against the under beveled surfaces of the blades of the upper propeller and thus further assist in preventing rotation of said upper propeller. The reverse action takes place when the propeller is pushed rapidly downwardly, the upper propeller being the one to rotate in this downward movement of the dasher. This alternating rotation of the propeller members will, as is obvious, impart to the milk a violent agitation with suflicient impact to break up the fat globules and produce butter.
The nature and scope of the invention having been thus indicated and its preferred embodiment having been specifically described, what is claimed as new is:
In combination with a staff having a journal pin at its lower end, a pair of propellers journaled on said pin and arranged close together, each of said propellers being provided with a plurality of blades having inclined upper and lower faces and also with a plurality of blades each of which is provided on one side with an inclined surface and on its opposite side with a fiat surface and on one edge with a vertical flat surface, for the purpose set forth.
In testimony whereof I hereunto aflix my signature.
THOMAS G. WADE.
