CENTRIFUGAL AND CENTRIPETAL CHURN, 



This engraving represents an improvement in the 

 churn dasher, recently patented by Mr. Z. C. Rob- 

 bins, St. Louis, for which a medal was awarded by 

 the American Institute at their fair last auttimn. 

 This dasher has a rotary motion, by a crank on a hor- 

 izontal shaft. The cut represents a transverse sec- 

 tion, or end view of the daslier. From the inven- 

 tor's specification, we gather the following account 

 of this machine. 



The dasher has several beating blades, a, a, h, h, 

 &c., confined at each end to arms c, c, &c., which 

 form the ends of the dasher. When the dasher is in 

 motion, tlic cream is gathered between the diverging 

 .surfaces of each pair of blades, giving it an outward 

 or centrifugal direction, and by the joint action of 

 pressure and suction, it is forced through the narrow 

 space between their after edges, producing a most 

 cflicicnt action on the cream for the production of 

 butter. 



When the butter logins to separate from the cream, 

 the motion is reversed, and the roar surfaces of the 

 blades, h, b, &c., will give the butter a centripetal 

 direction, and gather the butter, as fast as it is 

 formed, into a roll in the centre of the dasher; 

 thereby preventing the clogging and obstruction to 

 the free movement of the dasher by the accumula- 

 tion of butter upon it; so that the churning operation 

 may be easily pursued, until all the butter is sepa- 

 rated from the cream, and gathered into a roll. This 

 dasher raay be used to advantage in cither a round 

 or square churn. 



•' The peculiar position of the dasher blades, caus- 

 ing them to pass edgewise through the cream, pre- 

 vents their putting tlie whole mass of it into a rt)tary 

 motion ; in conseciucnce of which absence of rotary 

 motion in the body of the cream, the efficiency of 

 the churning action of the dasher blades is greatly 

 increased, and the dasher can be operated witl> oqual 



advantage in either a round or a square vessel. This 

 form of churn dasher, it is believed, has the largest 

 amount of rfTcctivo agitating surface that can pos- 

 sibly be given to it, consistently with the preservation 

 of such a degree of simplicity of form and arrange- 

 ment of parts as will allow of free access to all the 

 surfaces thereof that are brought in contact with 

 cream, for the purpose of cleansing them ; without 

 wliich last qualification, no churn will receive favor 

 with dairy-women. 



"The centrifugal and centripetal churn dasher is 

 equally well adapted to the churning of milk as it is 

 to the churning of cream. After repeated experi- 

 ments, it is believed I)y the inventor, that it will pro- 

 duce butter from crcnm or milk in less time, and w ith 

 a less expenditure of power than it can be accom- 

 pUshed by the use of any other churn that has ever 

 Ijccn patented or brought into use. 



" And also, that a larger quantity of butter will l>e 

 produced from a given (Hiantity of cream or milk." 



yVc copy the following fi-om that very valuable 

 work, the Farmer and Mechanic, New York : — 



"This invention, to which we alluded in the Farm- 

 er and Mechaiuc of November 1, api)ears to us to bo 

 based on purely scientific principles, and from the 

 extensive sale, and numerous testimonials in their 

 favor, their practical utility has not been ovor-esti- 

 nratcd. Hundreds are in use in our own state, in 

 some of the best dairies, and all who have used them 

 speak of them in terms of enthusiastic approbation. 

 We are informed that many are also in ajjeration in 

 Maryland, Virginia, and the District of f^olumbia, 

 where thoy are equally admired, saving, it is said, 

 by their application, nearly fifty per cent., in time and 

 labor, over the common upright reciprocating dasher. 

 Any contribution to the great dairy interest of the 

 country is worthy of high commendation, and this 

 we deem a valuable improvement, and worthy of 

 general adoption by the farming community."
