BUTTER- CHURNS ON A NEW PRINCIPLE. By C: HAREAND. (WITH A DESCRIPTIVE PLATE.)

VW preſent to our readers, a ſketch of an improvement in

the manner of working the Butter Churn. The tire- ſome vertical motion of the common churn, and the aukward rotatory motion of the barrel churn, are here aboliſhed, and ſupplied by a very eaſy muſcular exertion, reſembling in ſpecies that of a common pump handle.—By affxing a fly wheel, the agitation of the cream is neceſſarily berformed in a more equable manner, and hence the butter is more perfely ſeparated from the whey. Perſons unuſed to the efe of the fly wheel, in re- gulating any motion, may eahßily be cónvinced of its tendency, by ceaſing to work the handle, in which caſe, the churn(with a regular diminution of motion) will continue to a& for ſome time of itſelf.

The barrel churn(in the plate) is moved by the intervention of a multiplying wheel, to moderate. its over violent motion. The head of the crank moving in the mortiſe(in the handle) cauſes the’rotatory motion, of the barrel with great facility. From experiments, it appears, that if the barrel be#xed, and the axis(in the inſide) to which the dafhers are attached, be made to ura, that the butter will be much ſooner completed. The ingenious mechanic, whoſe inventions are before us, has a churn(with this alteration) in hand,

An improvement in communicating the vertical motion to the common churn, is alſo delineated in the plate.—The fly wheel and crank is applied, as in the other inftance, and wich the ſame egquable effe&. When we conſider, that moſt butter is made in ſmall quantities, and that the vertical motion of the common churn is ſo intolerably fatiguing, we cannot but con- ſider this application of the invention as far the moſt valuable. Nor can we deny, that we feel a confiderable partiality for the good old houſewife’s uſual churn: if the barrel churn had been found equally ſucceſsful, we think the old faſhioned churn,’ere now, muſt have been quite ſuperſeded.—T'he limits of the vere tical motion, are(of courſe) double the length of the crank, whoſe énd is inſerted in the mortiſe of the handle. he ſame apparatus may be applied for making different quantities of butter, by placing a, larger or ſmaller churn on the platform.
