Inraovnillnnr 1N cHUnN-DASHERS.

TO ALL WHOM IT MAY CONCERN :l Y 4 Be it known that I, JOHN W. BARTON, of Clifton Springs, in the county of Ontario, and State of New York, have'invented a certain new and useful Improvement in Churn-Dashers; and I do hereby declare that thev fol'- lowing is a full and exact description thereof, reference being had to the accompanying drawings, makingpart of this specification. l v

Figure 1 is a vertical section of a churn and an elevation of my improveddas'her-arrangement applied thereto.

Figure 2 a perspective view of the 'flasher-arrangement detached; from thej churn.

Like letters of .reference indicate corresponding parts in both figures.

My invention consists of an arrangement of double-'acting dashers, connected withva lever -at the top, and a jointed cross-piece at thebottom, for holding the dasher centred, the whole forming a separate and detached apparatus capable of being applied to any ordinary cylinder-churn.

v In the drawings, A isa central standard, having jointed at its lower end a cross-piece, B, which is intended to rest inthe bottom of the churn', and keep the dasher centred properly. Atthe top of the standard is pvoted a double-acting lever, C. To this lever are jointed dasher-rods'D D, each rod having at its lower en d two 'dasher wings E G, ofA segmental form, and situated at some distance apart. The upper Vwings E are made solid or closed, `but the lower wings G-lrave holes a a made through them vertically, as shown. Eyes, b Z, attached tothe inner edges of the lower wings, slide up and down" upon wire ways c c, secured to the sides of the standards.

v Thus arranged, it will be perceived that the operating parts are combined as a wholefready to berapplied to any churn. The cross-piece B resting in the bottom, and the standard resting in the cover, thedasher is properly centred, and not only this, but the wings-running upon the ways c c, insre a steady and uniform action. In washing, the whole arrangement is removed from the churn at one motion. The ways a 'c not only hold the dashers `in position, but also lessen the friction by keeping said wings from contact with the churn atany time. The wings, therefore, act only upon the cream, producing the greatest `effect with the lsmallest expenditure of power. The cross-piece being jointed at d, adapts itself always to thelbottom of the churn at whatever-position the dasheriis placed inside, ,and therefore it is steady in its hold, and obviatesirregularity that inight otherwise "occun lThe holes a a; of the lower wings allow apassage of the cream up through in streams, and these streams, striking the closed upper wings, are deflected andllroken, and 'tumbling inward' toward the centre ofthe churn,

.. they come vin contact with the opposing wings`of the other side of the c hhrn, which completes the agitation.

This arrangement of the wings is very effective 4in breaking the globules. l L I am aware that various arrangements of double-acting dashers have; beforefbeen known ;"I' do not claim broadly the principle. The novelty my invention lies only in the arrangement ofthe several parte combined as a whole,- and the improved arrangement'of the open and 'closed double dasher-wings, wherebythe'agitation'is increased. It will be noticed that the slots pp, in the lever, in which the upper ends of the dasher-rods rest, are made of considerable length, to allow the said lrods to be changed fromoneto the other of the holes? r, by which means both.the leverage and the extent of strokemay be changed at pleasure, to adapt to'therquantity of cream being churned, or to dili'erent-saedclrurns, asmay b e desired. I'prefer also to make elbows s e,.to the dasher-rods, to adapt them to the right positionl inthe churn.

What I claim as my invention, and desire to secure by Letters Patent, is The arrangement, as a whole, of the jointed crosspiece B, standard A, ways c c, open and lclosed dashere wings E Gr, rods D D, and lever C, the several parts being so combined as to form one connected working apparatus, as and for the purpose herein set forth. v 'l In witness whereof, I have hereunto signed my name in the presence of two subscribing' witnesses.
