SPECIFICATION forming part of Letters Patent No. 739,648, dated September 22, 1903.

Application filed September 23, 1902. Serial No. 124,529. (No model.)

To all whom, it may concern.-

Be it known that I, ALGOT LEVIN CHRIS- TENSON, asnbject of the King of Sweden and Norway, and a resident of Sturegatan 13, Stockholm, Sweden, have invented a new and useful Improvement in Centrifugal Separators, of which the following is a specification, reference being had to the drawings accompanying and forming a part hereof.

This invention relates to improvements in centrifugal separators.

The object of the invention is to provide a liner which will be of the simplest possible construction and at the same time of great efficiency. v

The invention consists, chiefly, in combining with a preferably conical mantle arranged placed radially or not and vertically orinclined, as desired.

In the accompanying drawings I have shown a suitable constructional form of my invention.

Figure 1 shows a vertical section of a cen-' trifugal separator-din m provided with a liner according to my present invention. Fig. 2 shows a top view of the drum and the liner, the cover of the drum and the plate securing the liner in position being partly broken away; and Fig. 3 shows the liner itself, seen from below. 7

The liner illustrated in the drawings consists of 2. preferably conical mantle 1, arranged centrally in a usual centrifugal drum 2 and provided in well-known manner with longitudinally-running folds, which at their outer parts are provided with holes or openings 3. V wings 4, extending from the outer parts of said folds to the wall of the drum 2.

be corrugated, as shown at 4, or folded in any convenient manner. Though I prefer to arrange the wings 4 in plane with one of the two sides of each fold, they may also be ar- To the said. mantle are attached.

The. said wings 4 may either be plane or they may .ranged in other manner, as shown at 4: and

4 in Fig. 2. The simplest manner in which the linerrnay be carried out is shown in Fig.

3. According to said figure the mantle and the wings are made of a number of metal plates 43, each of which is bent at an angle forming an inward fold of the mantle.

The said metal plates may he soldered together or fixed to eachother in any other convenient manner, so that they form a combination of a mantle and wings of the same kind as described above.

The drum 2 is in well-known manner provided with a central inlet-pipe 5, which, howevelymay be dispensed with, if desired. The said inlet-pipe is at its lower end provided with openings 8 for the full milk, let into axis of the drum that the wall of cream during the separation will place itself in line with the inner parts of the folds of the mantle at the top of the latter.

The liner may be held in position by means of a ring-shaped plate 9, the central opening of which may be of such size that the plate rests only on the wings, as shown at 9 in Fig.

2, or the inner edge of the plate may be cut' out in accordance with the upper edge of the folded mantle, as shown at 9 in Fig. 2. In

this case the points of the plate thus obtained blue milk gradually separating itself from the cream will flow out through the openings of themantle. The cream particles following the blue mill; through the said openings will immediately move inward into the folds of the mantle and flow upward toward the cream-outlet 7 of the drum. Since the said cream'outlet is arranged at such radial distance from the geometric axis of the drum that the wall of cream reaches somewhat into the folds of the mantle, the said folds may be made so deep as to leave sulficient space outside the wall of cream for all the full milk gradually let in through the inlet-pipe 5 in order that the said full milk may not disturb the wall of cream nor mix itself with the latter. Obviously, also, the inward folds of the mantle may be provided with openings,

partition, substantially as and for the purpose set forth.

2. The combination of, a centrifugal separ rator-bowl having cream and blue-milk ontlets and an inlet-pipe for the full milk, and a liner inside said bowl consisting of a longitudinally-folded partition, and wings attached to and extending from the outer parts of the folds of said partition, the latter being provided with outlet-openings at the outer parts of the folds, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
