2 Swivel-headed Churn Staff, 



I have tried it in a variety of forms and sizes ; with 

 six wings the labour was less relieved ; also when I 

 gave less bevel to the ends of the wings. 



When I gave more bevel it passed through without 

 producing the intended effects. Experience therefore 

 has convinced me, that it is best to have four wings 

 from six to seven inches in length, from the centre, 

 according to the size of the churn for which it is in- 

 tended, from two and a half to three inches in breadth, 

 made plane in the centre or middle, about the fourth 

 part of their length, and then bevelled regularly off, so 

 that the extreme point shall form an angle of about 45 

 degrees with the plane of the middle. The plane part 

 acts with its usual force upon the middle of the body 

 of the milk ; and the points turning rapidly round give 

 a kind of compound motion to the whole, and that also 

 alternate, and yet it does not in the least splash or throw 

 out the cream as in the common mode. 

 I am, Sir, 



Your obedient servant, 



TIMOTHY FISHER, 

 Gun-maker. 



Thomas Ecclestone, Esq., of Scarisbrick Hall, near 

 Ormskirk, certified, that he had seen Mr. Fisher's new 

 method of churning butter, and that he thinks it supe- 

 rior to any he had heretofore known for that purpose, 

 and that such was also the opinion of sevet-al other per- 

 sons in the farming line who had witnessed its effects.
