CENTRIFUGAL CREAM ER.

SPECIFICTION forming part of Letters Patent No. 697,170, dated April 8, 1902.

Application filed August 6, 1901. Serial No. 71,102. (No model.)

To fZZZ uf/Loin it may concern:

Be itknown that we, HERMANN RECK,asub ject of the King of Great Britain, residing at l Ilolborn Circus, in the city of London, England, and ANATOLE BORSU, a subject of the King of Belgium, residing at Falkstrasse 4, Bielefeld, in the Empire of Germany, have invented certain Improvements in Centrifugal Creamers,ofwhich the following is a speciiieation. A

The invention relates to that class of centrifugal machines adapted for separating two liquids of different densities from their mixture; and it is primarily designed to facilitate the separation of cream from the whole milk, so called. In the claims hereto appended the precise improvement will be set out in connection with the accompanying drawings, in which- Figure l is a vert-ical section of the separator. cylinder which incloses a divided liner. Fig. 3 is an elevation of the divided liner, and Fig. at is a plan View thereof.

Referring irst to Fig. l, the drum Z, provided with a cover, is rotated in a suitable casing. g is a sleeve to which are attached the ribs CZ. This sleeve is formed of a hollow cylinder which when placed over the central section of the bowl forms a passage for the whole milk, which passes thence through'the delivery-tubes 7L h into the bowl. Outlets are provided for the skim-milk through the tubes m n, and for the cream at 7o through the screws shown, these latter being adjustable to'allow of the thickness of the cream-layer being varied. a a are the plates, which are shown in this case fourin numberand tapered vertically, so as to be nearer the central sleeve g at the top than at the bottom. They are attached to this sleeve g by means of the ribs d, and are further connected with each other by pieces b l) l), so that the one plate is held apart from the other and so that one edge fis held nearer to the center of the bowl than the other edge e. As to which edge is the nearer to the center depends upon the direction in which the bowl is rotated, being, as shown at e and f, when the direction is that indicated by the arrow in Fig. 4. On

Fig. 2 is an elevation of a corrugatedr the outside ot' the plates a wings c are provided, which may either adjoin the edge e, as shown, or may be attached in any other suitable position on the outer surface of each plate. The bottom edges of the plates are bent so as to forni a iiange q, on which rests the perforated cylindrical covering t, and this in conjunction with the wings c divide the interior o f the bowl into a series of cells, thus preventing the readmixture of the milk and cream particles after once being separated. These plates may be of a larger number than four in larger-sized machines.

The whole milk enters the bowl through the tubes h, as shown by the arrows, when it immediately flies against the plates a if the bowl is empty and gradually proceeds to iill the bowl. The free surface of the liquid approaching the center is a vertical and approximatelya straight line if the drum is revolving at full speed. When the vertical line of liquid approaches as near to the center as the outlets le and n, cream and skim-milk, respectively, will immediately issue therefrom. When the bowl is revolving under normal conditions, it will be filled to the vertical level of the outlets, when the Whole milk enters at h and separation will begin almost immediately, the lighterglobules of cream going at once to the center and the skim-milk passing outward until it meet-s the plates a, when it is directed either down under the iiange q or out through the slots between the edges ef. In the former case itis the most easilyseparated milk which passes to the outside of the cylindrical cover i and rising in the space between the cover and the side of the bowl reaches the mouth of the outlet-tubes m. The milk passing through the upright slots is not wholly separated and undergoes a further separative action in the space between the plates a and the cover, which is divided into cells by the wings c. The cream particles here separated pass up the slanting surface of the plates a to the top of the creamcolumn, and the whole milk passes out of these spaces through the perforations in the cover t.

The cover is prevented from turning relatively to the plates by a suitable holding device, such as the slot o, in which one of the vwings c can slide.

their upper ends with said sleeve, said plates also being inclined upwardly toward said sleeve and forming 'a diyided l/iner having slots extending froufhase to top of the liner, and suitably connected together, substantially as set forth.

2. .In acentrifugal separating-machine, the combination of a rotating bowl and a central feed-sleeve having a series of arcual plates provided with radial ribs connecting them to said sleeve and inclined upwardly and toward said sleeve, and forming a divided liner having slots extending from th`e base to the top of the liner, said plates being connected upon opposite sides of said slots by shortpieces, substantially as set forth.

3. In a centrifugal separating-machine, the combination of a rotating bowl and a central feed-sleeve having a series of arenal plates inclined upwardly and toward said sleeve and having slots therebetween, also having radial ribs connectingthe edges of said plates nearest the center of the bowl with the said central sleeve, forminga series of partially-closed cells, around said central sleeve, connected with the space outside ot' the liner-plates by said slots.

4. In acentrifugal separating-machine, the combination of a rotating bowl and a central feed-sleeve having a series of arenal plates provided With radial ribs connecting them to said sleeve and inclined upwardly and toward said sleeve, said plates forming a divided liner with longitudinal slots between the edges of the plates, and radial wings attached to the exterior edges of said linerplates, farthest from the center of the bowl.

5. Ina centrifugal separating-machine, the combination of a rotating bowl and a central feed-sleeve having a series of horizontallycurved plates connected by radial ribs to said sleeve and inclined upwardly and horizontally toward said sleeve, said plates forming a divided liner with longitudinal slots between the edges of the plates, and radial wings attached to the exterior surface of said plates.

6. In a centrifugal separating-machine, the combination of a rotating bowl,a central feedsleeve having a series of horizontally-curved plates connected by radial ribs to said sleeve and inclined upwardly and toward said sleeve, said plates forming a divided liner with 1ongtudinal slots between theedges of the plates, and a perforated cylindrical cover inclosing said liner-plates, open at its upper end and mounted on the lower edges of the plates, and separate outlets for the cream and milk.

7. In a centrifugal separating-machine, the combination of a rotating bowl and a central feed-sleeve having a series of horizontallycurved plates connected by radial ribs to said sleeve and inclined upwardly and toward said sleeve, said plates forming a divided liner, radial wings attached'thereto, a perforated cylindrical `cover inclosing said liner and forming, with said wings, partiallyclosed cells, said plates having between them longitudinal slots connecting the cells on the interior with those on the exterior of said liner.

8. In a centrifugal separating-machine, the combination ofa rotating bowl, a central feedsleeve having a series of horizontally-curved plates connected by radial ribs to said sleeve and inclined upwardly and toward saidsleeve, said plates forming a divided liner, with longitudinal slots between the edges of the plates, radial wings attached to said plates, a corrugated cylindrical cover inclosing said plates and having perforations in the depressions and ridges of the corrugations, outlets at the top of the bowl for the cream, and pipes having their inlet at the top of the bowl and their outlet at the bottom of the bowl for the outflow of the skimmed milk.
