CENTRlFUGAL CREAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 628,725, dated July 11, 1899.

Application filed February 25,1899- Serial No. 706,813. (No modelf:

To a/ZZ whom t may concern:

Beit known that I, ERIK GUSTAF N IcoLAUs SALENIUS, a subject of the King of Sweden and Norway, and a resident of Stora Kraftriket, Albano, Sweden, have invented certain Improvements in Centrifugal Separators, of which the following is a specification.

This invention relates to the class of separators used for separating cream from milk; and it has for its object to provide suchva separator with means for spreading and distributing the iniiowing liquid outwardly over the internal inclined partitions therein, the latter being of a known construction. These internal partitions are in the nature of superposed inclined plates, and the main central tube of the drum is, for the purposes of this invention, flared or enlarged at its lower end and provided with distributing tubes or devices, which latter extendupward to the cover of the drum, above the inclined internal partitions therein. The upper portions of these distributing devices are slotted or perforated, so that the milk rising therein can now out therefrom onto said internal partitions, all as will be more particularly hereinafter described.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure l is a vertical axial section of the drum of the apparatus and its internal mechanism or devices. Fig. 2 is a plan of the bottom piece g in the drum on which the superposed internal partitions are placed, the drum itself being seen in horizontal-section. Fig. 3 is a side elevation of the main central and distributing tubes detached from the drum, the bottom piece g being seen in this View in vertical axial section, taken at right angles to the section in Fig. 1. Fig. 4 is a plan view of the main central and distributing tubes detached. Fig. 5 is a fragmentary vertical section, and Fig. 6 a horizontal section,illnstrating a modified construction of the distributing device.

Referring primarily to Figs. 1 to 4, inclusive, lc is the drum proper, h is the cover thereof, g is the bottom piece in the drum, and f are the inclined and superposed internal partitions in the drum between the cover h` and the bottom piece g. The cover h is de- 5o pressed or hollowed and shaped to fit onto the inclined partitions f, and it has radial ribs to strengthen it. The cover is secured in place on the drum by means of a ring s and screws t. In general these features are already well known.

The main central tube a, through which the liquid, as milk, is admitted to the drum, is flared or enlarged at its lower end b and provided at this flared portion with suitable np- 6o right sockets c, in which are iitted upright distributing-tubes CZ, of which four are shown herein, Fig. 4. The sockets c are or may be integral with the flared Wall of the portion l), and they and the tubes cl open into the conical chamber Within the portion h. The foot or lower end of the main central tube may iit into a central opening in the base portion g of the bottom piece g or it may rest directly thereon, and at the top said tube is steadied 7o and held in position by the cover 7L, which has a short neckpiece it', embracing the reduced upper end of the central tube, above a shoulder h2 on the latter.

It will be noted that the internal partitions f are roof-like or Wedge-like and not conical, and that the cover 7L is of a corresponding shapeand fits down upon and over said partitions, as already stated'. The main central tube ct is provided exteriorly with radial 8o iianges b', situated between the tubes d. These iianges project out about as far as the ilared base b of the central tube and extend up to and iit under the cover h. The internal partitions f have central apertures of su- 8 5 cient size to enable them to embrace the iianges b and tubes cl.

The tubes d have each a slot d in its outer face, extending from its upper end down to about the level of the lowermost partition j' 9o of the series, or, in other Words,to about the level of the top of the bottom piece g.

The discharge-passages Z for the skimmed milk and the discharge-passages m for the cream open out through the neck on the drum- 9 5 cover h, and these outlets are controlled by a sleeve p, which is ported and rotatable about said neck, being held in place by a screw-cap 2 i Geef/'c5 .betaken out together.

q on the upper end of said neck. The fixed pipe r for the admission of the milk extends down through an aperture in said cover and down throughthe main central tube to near the bottom of the drum.

The milk descending through the tube i' into the chamber within the flared `portion or base .by Way of the discharge passage or passages m.

Apertnres e, Fig. 1, allow slime and other impurities fromrthe milk to escape from the chamber within the enlarged portion b of the central tube out into the chamber g2 within the bottom piece g.

Vhen the internal devices of the drum are to be removed, thevcover h is rst taken off. The partitions flare'then taken out, and the vparts including thel main central tube and the distributing-tubes (seen in Fig. 4) can then This ability to remove allthe distributinginstrum en talities together possesses an important advantage over constructions where the distributing features are fixed separately in the drum. On the other hand, if a simple central tube only is employed, the partitions f do not perform the ffull function required of them.

VThe modified construction illustrated in Figs. 5 and 6 differs from that already de'- scribed in the substitution for the slotted distributing-tubes d of integral, hollow,.lateral, and radial enlargements a2 on the lower portion of the central tube d, as clearly shown in Fig. 6. At their outer upright edges the enlargements a2 have each a series of apertures or perforations for the escape of the milk. These enlargements a2 may project far enough .to enter recesses formed in the inner edges of the partitionsf, as indicated in Fig.

6, where the inner circular margin of tlie parl titions is indicated by a dotted line. y Having thus described my invention, I claiml. In a centrifugal separator, the combination with the drum k, the bottom piece g, the

depressed cover h, and the superposed partitions f, in the drum and embraced between the said bottom piece and cover, the latter parts being inclined to it the partitions, of the main central tube a, having an enlarged lower end b`provided with a plurality of concentrically-arranged distributing devices, said devices being substantially within the central apertures of the partitions f and upright, apertured faces adjacent to said partitions, substantially as set forth.

2. In a centrifugal separator, the combination with the drum, the bottom piece,and the superposed partit-ions in thedrum, of means for distributing the milk over said partitions, said distributing means comprising a main, central tube enlarged rat its lower end and provided with sockets c,and the upright tubes d in said sockets, said tubes being concentrically arrangedabout the central tube and having apertures in their outerfaces for the escape of the milk7 substantially as set forth.

In a centrifugal separator,the combination with the drum 7a, the bottomvpiece g, the inclined ,superposed,and apertu red partitions f,and the depressed cover h, saidbottom piece and cover being inclined to fit themselves to the inclined surfaces of said partitions, of the main central tube a,having an enlargedflower portion b, and the upright distributing-tubes .as set forth.

In witness whereof I haverhereunto,signed my name in the presence of two subscribing witnesses.
