SPECIFICATION forming part of neissued Letters. Patent No. 12,055, dated November 1s, 1902.

Original No. 565,279, (lated August 4,1396. Application for reissue filed October 24,1902. Serial No. 128,674. i r` To al?, whom'l t rnavy concern:

Be it known that I, PERLEY L. KIMBALL, a citizen of the United States of America, residing at Bellows Falls, in the 'county of W'ind-v ham and State of Vermont, ,have invented a 'certain new and useful lniprovementin Centrifugal' Machines for Separating Liquids o f Different Densities v and Specially Adaptable to the Separation of Cream from New Milk, of which the following is a description, reference being had to theiaccom panying;'draw-V ings,"v`vherein' i Figure l is a View in central vertical section of a separator embodyingr said improvement. 2 is a side viewof one of the circular partitions made use of-'the one next the outermost. Fig. 3 is a top or plan view of the nest or set of ci rcuiar partitions con tained within the separator-drum on a somewhat-enlarged scale. 'lhe arrows indicate the course of the milk through the openings in the cir- 4 ,cular partitions from one canal to another'.

' The mechanism is described herein applied to the separation of cream from new milk. i l

The letter a denotes theswiftly-rotating separator-drum, a cover screwing upon the same, and c a packing-ring between the two.

` The new or Whole milk enters through' the feed-pipe (l and escapes therefrom through tubes d'. Undercentrifugalaction theheavier portions of the whole milk--the Wateryconystituents-tend to seek the inn'er wall of the drinn a and in so (loing tend to force the cream into a central mass. In this machine the liquid in order to reach the inner Wall of the drum must travel a zigzag course through canals formed between the circulaipartitions, t-he liquid passing from one such canal to another through openings made for.

that purpose in such circular partitions.

The letter c Adenotes such 'circular partitions one within the other'. -'l`o the inner Wall of each of these circular partitions', except the innermost oue,.there is attached at opposite parts' ofthe circle a grooref, reaching from top -to bottoni of the partition. At correspending positions on the outer wall of the next inner circular partition there are at-l tached bladesjgvfrom top to bottom, which lit and run inthe grooves j. arrangement of ways the circular partitions-fit to and within one another and are separable and detachable from each othe,1 a construction .which facilitates.,- manufacture, assembly, and cleaning. At points intermediate of these ways there are projections or stays h fast on the outer walls of the circular partitions t'or the purpose of steadyiug them in place-With reference to each other. The

. ways just described also act as stop-walls in thecanals, which exist between the circular partitions, so that such canals donot permit the liquid to travel the 'entire circle.4 Next each of these stop-walls there is a vertical line of holes p through the circular' partitions, which form openings for the passage of the liquid first into the innermost of the canals and then successively into andthrough the others until the liquid reaches the inner wall of the drum a. The arrows in Fig'. 3 show the location of these openings and indicate the course ofthe liquid. Such openings in one partition are out of alinement with the similar openings in the two partitions next adjacent-on either side.

By means of this In the plan View, Fig. 3, the vertical line of openings in the outermost partition appears on the inclined wall of the partition, as shown at 7) p. The arrows at those points indicate the course of the milk through the Whole line of vertical.A apertures as it emerges through the outermost partition into the space separating the latter from the wall of the drum.

While thel milk is yet in .the central space, o

separation of the cream from the more watery constituents of the mil-k takesv place to a very considerable degree and the cream collects into a central mass. \Vhile the milk is travcling through the canals the heavier constituents coistantly seek the outer wall olf the canal in which the liquid then is, rforcing,r the cream against the inner wall of that canal, along which it riscs,cscapcs at the open upper end, and then joins thc central cream mass. It passes ont of the sci arator through the cream-outlet i. The watery part, generally called the blue milk, reaching the inner wall lof the separator-drum passes out of the separator through the blue-milk outlets j, more or less in number. Y 4

'The assembled set or nest of circnlarfparti- Vtions either rest directly on the door of the separator or the lower end of the same 'may be providedA with a removable cap l. The wings m on the outermost wall of the outermost circular partition assist in making the liquid rotate with th'e separator-drum. The
