To e53 whom it may concern Be it known that I, PERLEY L. KIMBALL, of Bellows Falls, in thecounty of lfinc'llmm and State of Vermont, have inventecl a certain 5 new and useful Improvement in Centrifugal Machines for Separating Liquids of Different Densities, Specially Applicable to the Separation of Cream from Milk, of which the following is a description, reference being had to the accompanying drawings, wherein- Figure 1 is a. view in central vertical sec-.- tion of amechanism embodying said improvement. Fig. 2 is a View of the same mechanism in horizontal section upon plane so a, :5 looking upward.

This mechanism will 'be described herein as applied to the separation of cream from Whole or new milk. The whole milk may enter the rotary soparatingbowl a by vessel over the bowl. The feetl-tube c conductsthe milk downwardly and delivers it near the bottom of the bowl. 'lhc letter 0', denotes a sheet of metal formed into a roll, with the sides of the sheet out of contact with each other, with the result of producing a continuous eccentric liquidchannel having a plurality of convolutions. This continuous eccentric liquid-channel r0- tates with the bowl a, and the part 61 bears o its exterior the wings e, Whose function is to cause the milk to rotate. The milk escaning from the feed-tube enters the mouth .:f the continuous eccentric liquid-channel and. gradually works its way entirely through 3 5 the some into the chamber (3, Where are the wings e. The eiiect of the centrifugal force upon the liquid as it traverses the continuous eccentric liquiri-cluirinel is to tend to force the watery and heavier o liquid age-inst the outer Wall, will. i .In turn forces the cream-globules against the inner wall, where theyare free to rise, and (lo rise, into the chamber B.

in tile operetion'of the machine the larger gravportions of the Patent No. 565,273, dated. August 4, 1896.

1894i. 8erialNo.504,-i95. (NomodaL) posed to an increased degree of centrifugal force, which operates to separate the smaller creamglobules, those which cling the more tenaciously to the Watery portions of the liquid. As the cream-globules are thus separatcd from the heavier and watery portions of the liquid, they rise along the inner Walls of the channel and all mass together in the upper chamber B and escape through the cream-outlet f into an annular cream-pun. When the liquid finally arrives in the chamher 0, it is nearly or quite devoid of cream particles, and this skimmed milk rises along the wall of the separator and flows out from the separator through the milk-tubes h into an annular milk-pan.

The wall of the continuous eccentric liquidchannel is made separable as a whole from the separator bowl a in order that it may be taken out for cleansing purposes. Likewise the feed-tube c is separable both from the separator-bowl and the walls of the liquidchannel. for a like purpose.

The coils dmay be secured together by the floor I), or in any other convenient manner.

I claim as my improvement-- In a centrifugal separator, the rotary bowl, having central feed-conduit with branch conduits near the bottom,'blue-milk conduits hi1, cream-conduits f, and a single spiral or convolute partition at, slightly contracted from the bottom upward, forming within its convolutio'as a continuous spiral channel, substantially as and for the purpose specified.
