CENTRIFUGAL CREAM-SEPARATOR,

SPECIFICATION forming part of Letters Patent No. 593,032, dated November 2, 1897.

Application filed June 16, 1897. Serial No. 640,975. (No model.)

To a/ZZ whom, it may concern,.-

Beit known that I, ERIK Gus'rnr NICOLAUs SALENIUS, a subject of the King of Sweden and Norway, and a resident of Kraftrilret, Albano, in the Kingdom of Sweden, have invented certain new and useful Improvements in Centrifugal Separatore, of which the following is a specification.

This invention relates to that class of centrifugal separators which have within the drum for the purpose of increasing the skiinming power of the apparatus various forms of partitions with their surfaces more or less inclined to the vertical axis of the drum; and the object of the present invention is to provide the drum with partitions having advantages over those heretofore employed and which are of annular form bent along one diameter and superposed in the drum.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure l is a vertical axial section of' the apparatus in the plane indicated by line 00' in Fig. 2. Fig. 2 is a horizontal section on the plane indicated by line 0:2 in Fig. l. Fig. 3 is a side elevation of the cover G of the drum as seen from the right in Fig. l, the drum and upper casing being in section and the cover G broken away at the left side. Fig. It is a side elevation, and Fig. 5 a plan, of one of the annular partitions detached.

A represents the drum of the separator, in the center of which is mounted the usual upright cylinder B, forming the milk inlet and receiving chamber. This chamber has four equally-spaced radial outlets b b and b' b at its bottom. About the base of the central cylinder B is an annular support C for the annular partitions D. This support C, which is seen in plan in Fig. 2 and which may be separate from or integral with the drum, as preferred, is inclined on its upper face oppositely from a diametrical ridge in order to properly receive and support the partitions D. These latter are made of thin material and are circular, as seen in plan, Fig. 5, but angular as seen in side elevation, Figs. lv and 4;. If the partition D be cut in its annular form from anat sheet, the inner and outer contours will have to be slightly elliptical, so

that when bent along the shorter diameter to the angle seen in Fig. 4 it will then be circular in plan. This is the construction seen in the drawings, but it is not necessary that great care shali be exercised in this respect.

lOn the partitions D are distancing cleats or devices d of some kind, so that when superposed, as in Fig. l, there will be spaces between adjacent partitions. Each partition has notches d in its inner margin to receive ribs b2 on the cylinder B when the partitions are in place.

The cover G rests on the pile of superposed partitions D to keep them down in place and prevent them from becoming distorted in the operation of the apparatus. There may be, if desired, a plate F interposed between the cover G and the upper partition. The cover G has a fiange g, which rests on the upper margin of the drum A, and on it is supported a shell GX, the whole being held in place on the drum by suitable clamps H.

. Thel liquid to be separated (as milk, for eX- ample) is admitted through the cylinder B to the bottom of the drum and flows out at the radial outlets Z7 t1 and b Zi into the hollow of the annular support C and thence back into the space inclosed by the partitions D. The outlets b deliver it at the sloping or inclined sides of the partitions and the outlets b at the higher ridged sides thereof. The centrifu gal force drives the liquid outwardly between the partitions to the space between the latter and the inner wall of the drum, and the heavier liquid thus separated iiows upward through outlet tubes or channels I. (Seen in Figs. 1 and 3.)

The support C and partition D are herein shown as placed with their upper faces inclining downward and outward from a diametrical ridge; but it will be obvious to any one skilled in the art that they may as well be inverted so as to incline upward and out- Ward.

Having thus described my invention, I claim* l. A centrifugal apparatus having superposed in its drum a series of annular partitions D, bent angularly along one diameter only, said partitions being situated substan- IOO tially concentric With the axis of the drum and separated to permit the heavier liquid to pass outwardly between them.

2. A centrifugal apparatus having a drum, an upright cylinder at the center of said drum to form an inlet and receiving chamber for J[he liquid to be Separated, said chamber having oppositely-arranged radial outlets at its bottom, and said apparatus having in its drum concentrically arranged and superposed partitions, D, of annular form bent along one diameter only, as set forth, said partitions being separated to form spaces or passages for the outward ow of the heavier, separated liquid.
