CENTRIFUGAL Ll-QU lD-SEPARATOR.
SPECIFICATION forming part of Letters Patent No. 732,520, dated June 30, 1903. Applicationfiled January 14, 1902. Serial No. 89,654. (No model.)
have invented certain new and useful Im-.
provements in Centrifugal Separating-Machines, of which the following is a specification. 1
This invention relates to centrifugal separators, and more particularly to such as are adapted fand especially designed for use'as cream-separators.
The invention seeks to provide a. machine of the character described of high efficiency, compactness,simplicity,and of comparatively low cost.
The invention consists of the structure hereinafter set forth, and pointed out injthe claims.
In the accompanying drawings, forming part of this specification, and in which like reference characters designate corresponding parts, we have shown one for1nz'. e. the preferred form-of our invention.
In said drawings, Figure l is a vertical section of a separator embodying the invention and taken on the line 1 1 of Fig. 2. Fig. 2is
a central horizontal section of the same, and
Fig. 3 is an elevation of the interior devices or partitions which constitute the main feature of the invention.
The bowl 1 is provided with a bottom 2 and top 3 and is supplied with inflowing liquid through a central supply-tube 4, having a head 5, by which the tube clamps the top 3 securely in place, said tube having threads 6, by which it is screwed in place into the block 7 in the bottom of the bowl. The block 7 has channels 8, through which the'infiowing liquid passes from the tube 4 into the bowl. Within the bowl are arranged a plurality of partitions A B, which it is best should be consuch radial section 10 connecting the inner edge of one oblique section with the outer edge of an adjacent oblique section. These oblique sections areprovided with inner and outer openings 11 and 12, respectively.
Within the outer partition A is another and concentric partition B, consisting of a plurality of sections 13, which are arranged obliquely across the radial lines of the bowl, and of a plurality of substantially radial sections 14, each of which connects the inner edge of one oblique section with the outer edge of the adjacent oblique section. The sections 13 are provided with outer and inner openings 15 and 16. The inner and outer partitions are preferably substantially similar, as shown, and it is best to so arrange them that the outer edges of the oblique sections of an inner partition are in proximity to the inner portions of the oblique sections of an outer partition, as is shown in the drawings. The outer partition is preferably supported by the inner wall of the bowl by contact therewith in the manner shown. Suitable means are provided for holding the partitions in fixed relation to the bowl, so as to prevent circumferential movement. As shown in the drawings, these means consist for the outer partition of a rib 18, carried on the bottom ofthe bowl, and a notch 17 at the bottom of the outer partition to receive the rib 18, and also consists for the inner partition of a rib 19, carried at the top of the inner partition and which fits in a recess 20 at the top of the outer partition. Both partitions are readily removable and replaceable carried by the inner partition, and they are so shown in the drawings, being secured to radial sections 14.
A conical ring 23 is located above the partitions A and B and extends to near the periphery of the bowl and so as to leave an opening 24 around its outer edge for the upward passage of the skimmilk or other liquid.
The ring 23 preferably rests upon and is held in place against circumferential displacement by the wings 21, as is shown in the drawings. The ring 23 also rests upon the partitions A and B, which slope upward and inward at their upper ends, but so as to leave a flow-space directly beneath the ring 23, as is shown in the drawings. The ring 23 is open at its top around the tube 4 for the free upflow of cream.
The top 3 carries several skim-milk ducts 25, which hold the ring 23 and the partitions A and B down in the bowl.
26 is the adjustable cream-screw.
The operation of the machine is as follows: The full-milk passes down through the tube 4 and out into the bowl through the ducts 8 and thence upward, the wings 21 and also the sections 10 and 14 of the partitions A and B imparting a rotary movement to the milk. The oblique sections 9 and 13 serve to guide the cream or lighteringredient inward toward the center and also serve to guide the skimmilk or heavier ingredient outward toward the periphery of the bowl. In this flow of the cream-currents cream passes inward along the outer sides of the sections 9 of the partition A and through the openings 11 and 16 toward the center. It also passes inward along the outer sides of the sections 13 and through the openings 16 toward the center, and finally upward through the opening in the ring 23 and out through the outlet 26. The skim-milk passes outward along the inner sides of the sections 13 through the openings 15, thence along the inner sides of the sections 9 out through the openings 12, thence upward through the opening 24, and out through the ducts 25. The ring 23 serves to guide upward and inward the cream or lighter ingredient which may gather beneath its under side.
It will be seen that the openings 11 and 16 are disposed in substantially radial lines, and thus aiford an easy and unobstructed flow for the cream inward, and that the radial sections 10 and 14 do not substantially interfere with the cream or skim-milk currents.
While we have shown in the drawings the preferred form of an invention, it is to be un derstood that various modifications may be made without departing from our invention. For example, the oblique sections 9 and 13 need not always be exactly flat or the radial sections 10 and let exactly radial. The oblique sections might be slightly curved from side to side, and the sections 10 and 14 might be somewhat out of radial arrangement, si1nilar to the curved plate shown in Fig. 4 of United States Patent No. 679,9 l8, granted to us August 6, 1901. Again, the benefits of the invention will be still obtained, though perhaps not to the same extent. Again, additional skimming devices may be arranged within the partitions A and B, and such devices may or may not be similar to the partitions A and B. Various other changes may also be made.
Of course it will be understood that the separator may be used for other purposes than that of separating cream from milk.
hat we claim, and desire to secure by Letters Patent, is-- 1. In a centrifugal separating-machine the combination with a separator-bowl, of a plurality of concentric partitions, each partition having a plurality of sections arranged in the liquid-space of the bowl and obliquely across its radial lines, and having also a plurality of substantially radial sections each connecting the outer edge of one oblique section with the inner edge of the next adjacent oblique section, the said partitions being so arranged that the outer edges of the oblique sections of an inner partition are in proximity to the inner portions of the oblique sections of an outer partition.
2. In a centrifugal separating-machine the combination with a separator-bowl, of a plurality of concentric partitions, each partition having a plurality of sections provided with openings along their inner and outer edges arranged in the liquid-space of the bowl and obliquely across its radial lines, and having also a plurality of substantially radial sections each connecting the outer edge of one oblique section with the inner edge of the next adjacent oblique section, said partition being so arranged that the outer edges of the oblique sections of an inner partition are in proximity to the inner portions of the oblique sections of an outer partition, and a conical ring located above said partitions and extending near the periphery of the bowl.

6. In a centrifugal separating-machine the combination with a separator-bowl; of a central supply-tube; a plurality of separableconcentric partitions, each partition having a plurality of sections provided with openings along their inner and outer edges arranged in the liquid-space of the bowl and obliquely across its radial lines, and having also a plurality of substantially radial sections each connecting the outer edge of one oblique section with the inner edge of the next adjacent oblique section,- said partitions with their openings being so arranged that" the outer edges of the oblique sections of an inner partition being in proximity to the inner portions of the oblique sections of an outer partition, and whereby the inflowing currents are separated from the outfiowing currents by said radial sections of the partitions; means for securing said partitions removably in place in the bowl; a separable conical ring located above said partitions; and radial wings extending inward from the inner partition.
In testimony whereof we have signed our names to this specification in the presence of 40 two subscribing witnesses.
