CENTRIFUGAL CREAM-SEPARTORL SPECIFICATION forming part of Letters Patent No. 656,423, dated August 21, 1900.

To a/ZZ whom it may concern: 5

Be it known that I, ERIK GUs'rAE NIooLAUs SALENIUS, a subjectof the King of Sweden and Norway, and a resident of Albano, in the Kingdom of Sweden, have invented certain new and useful Improvements in Centrifugal Vessels or Drums, of which the following is a specication.

This invention relates to the drums or vessels used in centrifugal machines; and the object of the invention is to improve the construction of vessels of this class which have interiorly-arranged rings carrying conical deilecting-plates.

An embodiment of the invention is illustratedin the accompanying drawings, where- 1n- Figure l is a vertical axial section of a centrifugal vessel embodying my improvements; and Fig. 2 is a horizontal section of the same, taken just above the bottom thereof. Fig. 3 is an enlarged sectional detail View of one of the rings, illustrating the manner of supplying one ring with more than one conical plate.

In carrying out'my invention in its preferred form I employ a cylinder or drum 01 which is relatively thin and of substantiallyuniform thickness from bottom to top, said drum having at its top an inturned ange or lug to receive screws f and a bayonet-fastening at the bottom, Fig. 2, for securing in it the removable bottom e. cover d, the ring-ange of which takes under The drum a may be inverted, the cover d put in place, then a series of rings b .put in place, which extend the entire depth of the drum from cover to bottom, then the bottom e pnt in place and secured, and finally the screws f may be driven down or in upon the ringiiange of the cover d, so as to press the rings h tightly together. The superposed rings ZJ fit snugly within the drumoJ and have between them, as also between the terminal rings and the bottom e and cover d, packingrings c, of suitable material to form tight joints. On each ring b is a deflecting-plate g of a known conical form, and in the plate g, adjacent to the point where it springs from the ring b, are apertures h for the upward flow of the skim-milk to the outlet-pipe 't'. Obviously each ring b may carry more than one plate g, as seen in Fig. 3, which shows This drum has a two concavo-convex plates on one ring. This construction provides an inner wall to the drum a made up of the rings b and reinforcing the outer wall of the drum, which may be relatively quite thin. The advantage of the construction resides in the fact that the inner wall of rings resists the internal pres- 6o sure and is economical to construct, While the wall of the drum proper, a, may be made much thinner than usual, and consequently at much less cost.

Having thus described my invention, I claiml. In a centrifugal vessel, the combination with a relatively-thin outer drum a, of uniform thickness from top to bottom, of aseries of rings b which fit into said drum and are 7o superposed, extending from the bottom to the cover of the drum and forming an inner reinforcing-wall therefor, the plates g on said rings, packing between said rings, and means for pressing the rings b firmly together, substantially as set forth.

2. In a centrifugal vessel, the combination with the relatively-thin drum a., having a wall of substantially-uniform thickness from top to bottom, of the rings l), tting into said 8o drum and superposed, the plates g on said rings, the packing c between said rings, the cover d, having a ring-ilange which rests on the top ring l), and the clamping-screws f, which are driven down through inturned iianges on the drum onto said ring-hangs of the cover, substantially as set forth.

3. In a centrifugal vessel, the combination with a relatively-thin drum ct, of substantiallyuniform thickness from top t0 bottom, and 9o having inturned flanges at its top to receive the screws f, the said screws, the cover d, and the removable bottom e, of the series of rings b, superposed within the drum and extending therein from the bottom to the cover so as to form a reinforcing-wall for the drum, and the plates g, carried by said rings, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing 10o witness es.
