CHURN-DASH ER.

SPECIFICATION forming part of Letters Patent N 025272022, dated October 2, 1894.

Application filed November 10.1393l Serial Nol 490,572. (No model.)

Be it known that I, GEORGE WASHINGTON PARRISH, a citizen of the United States, residing at Salem, in the county of Roanoke and State of Virginia, have invented a new and useful Churn-Dasher, of which the following is a specification.

My invention relates to improvements in churn dashers, and has for its object to provide a simple, inexpensive and efficient device adapted to be used in connection with an ordinary' churn body or tub, and Aconstructed to simultaneously cutand whip the contents of the churn.

Further objects and advantages of this invention will appear in the followingdescription, and the novel features thereof will be particularly pointed out in the appended claim.

In the drawings: Figure l is a perspective viewof the dasher embodying my invention applied in the operativeposition to a churn tub, the latter beingbroken away. Fig. 2 is a vertical central section of the dasher. Fig. 3 lis a detail View of the dasher-head, hollow shaft, and spiral actuating spring. Fig. et is a detail view of the socket.

Similar numerals of reference indicate corresponding partsin all the figures of the drawings. f

l designates a vchurn tub, and 2 the dasher embodying my invention.

3 represents a vertical guiding post, which is arranged centrally in the churn tub and is stepped at its lower end in a socket 4, which is secured to the bottom of the tub; and 5 represents a hollow dasher-staff having a bore which correspondsin size with the guiding post, the dasher 6 being secured to the lower end of said staff. The staffis provided with a series of vertical slots 7, which penetrate to the bore thereof, and thus reduce the frictional contact of the surface of the guiding post with the bore bf the staif and facilitate the removal of any foreign matter which may accumulate in the bore. VArranged between the under side of the dasher-head and the upper side of the socket/1, and coiled upon the intermediate portion of the guiding post, is a spring 8; and secured at its upper andy smaller end to the under side of the dasherhead `and at its lower end or base resting upon the bottom of the churn tub is aspiral spring 9, the latter being of sufficient diameter to receive Aand extend around the socket-plate 55 the dasher to be operated with ease and rapidity, and at the same time the spiral spring serves as a means of cutting the cream-and hastening the separation of the biitter and milk, the dasher-blades, meanwhile, acting as concentrators to collect the butter. -It will be understood, furthermore, that in smally churus, or` when a small quantity of liquid is being treated, the guiding post, socket and coiled spring may be omitted, saidparts being removable from the staff and dasher-head by withdrawing the guiding post from the bore of said staff. l

The construction ofthe improved dasher is simple and it isobvious that the same may be constructed at a small cost.

The socket 4 ycomprises a base l0, and a barrel 11, said barrel being provided with a vertical slot l2, which communicates at its lower end'with a transverse odset 13, andthe guiding post which fits in the vsleeve portion SQ vof the socket isprovided with a lateral fixed' pinle, to engage said communicating slot and secure the post in an" upright position. By this construction the guiding post is detachable from the churn body or tub for purposes of cleaning, dac., and to permit of the independent use of the dasher and spiral spring, as shown in Fig. 3. l .4

' Various changes in the form, proportion,

and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having described the invention, what is claimed isy y The combination with a churn tub, of a socket fixed to the bottom of the tub at its center and having a vertical sleeve or barrel provided with a vertical slot terminating in a lateral offset, a guiding post adapted to fit roo in the sleeve or barrel of the socket and provided with a lateral pin to engage said slot and offset, whereby the guiding post is detachable i from ;the `churn tub, i a tubular slotted staff slida'bly fitted upon the guiding post, a flasher-head fixed to the lower end of the tubular staff, a coiled spring arranged between the dasher'head and the socket and coiled around the guiding post, and a spiral spring fixed at its upper end to the under side of the dasher-head and resting at its 1o base upon the bottom of the churn tub around said socket, whereby the said spring is adapted to fold `compaotiy `when the dasher is depressed, substantially as specified.

, In testimony that I claim the foregoing as my own I have hereto affixed my signature in I 5 the presence of witnesses.
