-the specification.

This invention relates-to JOHN .MILLEIR. FLEMING, or EDMONTON, ALBERTA s gamma.

DASH- H IR To all whomz'tmay concern:

Be it known that 1, JOHN MILLER JFLEM- mo, of the :city of. Edmonton, in the Province of Alberta, Dominion of Canada, have in vented certain new anduseful Improvements in Dash Ghurns, of 'whichthe following is improvements in i dash churns and the object of the invention is to providemeans for drawingai-r down into the-body of the cream "so thatuit W111-pass up through the cream and thereby drive all impurities from the cream and produce a better grade of butter and'atthe same time provide a .machine which will economize both time and labor and which may be readily adjusted :for the different sizes of vessels and: different depths of cream. It

consists essentially. of the following-arrangement of parts as hereinafter more part cularly explained by the following specification.

Figure 1 is a side elevation ofiny churn showing'th'efcrieam containingj vessel, dasher and major portion-of the supporting structure' for-"the operating mechanism int-section. Fig. 2 is an enlarged sectional viewl'ofithedasher.

Fig. 3 is a plan section on line my Fig. 2.

Fig. 4 is a plan section on line a:y' Fi fn the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates the main base or foot of the machine provided with a central tubular portion 2 split vertically at 3 and provided with lugs 4 and 5 through which a bolt 6 extends to draw the split ends of the sleeve together. 7 is the main standard or column. 8 isa table secured to the upper end of the column 7 and provided with a recessed portion 8 as indicated in the dotted lines in Fig. 1, into which a vessel 9 for containing cream fits at its base. 10 is a supplemental hollow standard extending upwardly from the table 8 and suitably secured thereto. The standard 10 is also provided with a split upper end 11 provided with lugs 12 and bolt 13 extending through the lugs to draw them together. 15 is the main casting for supporting the operating mechanism of the machine. 16 is a side shaft extendin from the casting 15 and on which is mounte a gear wheel 17 provided with a crank handle 18 in proximity Specification of ietters Patent.

screw .32.. is a cylindrical member surrounding the rod 315-thenrod being secured centrali y within the cylindrical member by

spiders

34 and 35 so as to form an annular space between the inner face of the cylinder 33land. the 31; x36 vis-ithe head of the vdashe'r comprising radially extending arms 37 and an annular rim 38 formed integral with the arms; the lower end of the tubular member 33 is provided with. an annular flange 39 and 40 are screws extending through the flange 39 into the head 36 whereby the head 36 is secured to the cylindrical member 33. 41 is a spider the upper periphery portion of which fits in an annular recess 42 formed in the head of the dasher 36. 43 is a rod slidable within the spider 41. 44 is a split pin extendingdiametrically from the upper end of the rod 43. 45 is a spiral compression spring extending between the split pin 44 and the spider 41. 46 is a metal disk forming the valve head fitting against the lower face of the dasher head 36 so as to normally close the orifice 36 formed in the center of the dasher. The disk 46 is provided with a central orifice 36 from which the lower threaded end of the rod 43 extends.

47 and 48 are nuts whereby the disk 46 is the pinion 22, shaft 21, crank, heel 23 an into the cylindrical member 33.

imparting thereby a reciprocating vertical movement with the rod 26 by means of the connecting link 27 extending between the rod 26 and the crank wheel 23. By this operation the dasher of the churn isrecip-e rocated vertically in the body of cream con tained within the receptacle 9. During the upward movement of the dasher the displacement of the cream creates a vacuum which draws open the valve formed by the disk 46 allowing air to rush through the tube 33 into such space formed by the displacement of the cream. During the downward movement of the dasher upward pressure of the cream forces the disk 46 upward against the head 36 closing the orifice 36 and thereby preventing the cream rising up The air which has thereby been drawn into the body of cream rises up throughsuch body and any impurities in the cream are united therewith and carried up thereby into the atmosphere, thereby clearing the cream of all such impurities." If it is desired to ad ust the apparatus in accordance with the size of the receptacle used or the depth of the cream within the receptacle, all that is necessary to do is to loosen the bolt 6 and raise the column 7 to the required height, the main casting'15 supporting the driving gear may also be adjusted by loosening the bolt13 and raising the casting15 upward to the required height and retightening the bolt 13. 1

Copies of this patent may be. obtained for my hand.

From this description it will be seen that I have devised a very simple form of dasher churn which may be operated manually with a minimum amount of power which may be operated more rapidly and thereby and into the center of which the lower portion of the dasher rod extends, spider members for comiecting the dasher rod to the cylindrical member, a disk valve bearing against the lower face of the head, a spider member supported within the cylindrical member in proximity to the head, a stem extendingfreely from the spider member to the lower end of which the valve disk is secured, a bearing piece carried by the upper end of'the stem, and a compression spring extending between such bearing piece andthe spider.

In witness whereof I have hereunto set JOHN :MILLER FLEMING.
