Specification of Letters Patent. Patented June 14,1910. 7

Application filed February 19, 1909. Serial No. 78,767.

To all whom it may concern:

Be it known that I, FRANK H. Fnnncn, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Centrifugal Separatora of which the following is'a full, clear and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to centrifugal separators, and particularly to the type shown in my rior United States Patent No. 792,577, ate d June 13, 1905.

One object of my present invention is to provide a separator 0f the type referred to having a separating cone arranged at the upper end of the bowl and constructed in such a manner that it can be removed quickly and thoroughly cleaned.

1 Another object is to provide a separator of .the character described in which the cone solution that is to be separated, and one or more chambers surrounding said bowl and communicating with the interior thereof for receivin and collecting the constituents of said so ution that are of comparatively greater specific gravity. And still another object is to provide a separator in which the arms that-are located inside of the bowl are arranged in a novel manner.

Figure 1 of the drawings is an elevational view, partly in vertical section, of a separator embodying the various features of my invention; Fig. 2 is a horizontal sectional view of the bowl. taken on approximately the line 2-42 of Fig. 1; Fig. 3 is an elevational View, partly in vertical sect-ion. of a modified form of my inventiomFig. elis a horizontal sectional view of the bowl shown in Fig. 3, taken on approxin'iately the line at-Ac .of said figure; Figs. '5, 6 and 7 are vertical sectional views of slightly modified forms of bowls; and Figs. 8, 9 and 1d are horizontal sectional views of the. bowls shown in Figs. 5, 6 and 7 respectively.

Referring, to the 'drawin s which illustrate the preferred form 0 my invention, 1 designates a stationary base on which a support or standard 2. is adjustably mount ed, as hereinafter described, said standard being provided with an arm or extension 3 that carries a vertically disposed shaft 4 which is adapted to be rotated by some suitable means;

The bowl A of the separator is connected to the shaft 4 so that it will rotate with same, and said bowl is provided with a removable top or cover B that has a screwthreaded flange 5 which is screwed onto the upper end of said bowl. This cover B has a conical-shaped portion that merges into a on its interior with a beveled seat that is' adaptedfto be engaged by a beveled collar 7 on thetubula r-shaped portion 8 of aseparating cone C that is arranged inside of the bowl A, as shown in Fig. 1. The liner that is arranged inside of the bowl consists of a hollow shaft D provided adjacent its upper end with a beveled. collar 9 that fits in a beveled seat on the interior of the tolerlar-shaped portion 8 of the cone C. th:.- up perend of said shaft projecting into a receptacle 10 that receives the solution which is to be separated. Said shaft D is provided with anumber of laterally projecting arms 11 that terminate adjacent the side of the bowl, and inthe construction shown in Figs. 1. and 2; said arms 11 are screwed directly into the shaft 1).

"The beveled collars on the liner shaft-l) and on the cone G are held in engagement with the tapered seats which they cooperate with by yicldingiprcssi'ire so as to form tight joints between said parts.

gagement; with its cooperating seat on the interior "of the tubulan-shaped portion 8 of the cone C. The upward pressure which the In the construclion-herein shown the liner shaft 1) is pro li ncr shaft'is thus subjected to will, of coursb, 3

tend to move the cone upwardly and thus hold the tapered. collar 7 on sald-cone in intimate engagement with its cooperating seat on the interior of the tubular-shaped portion 6 of the'top or cover B of the bowl.

The bottom of the bowl is provided-with suitable grooves. 01' shoulders, for receiving the lower ends of the vielding devices or extensions 12 on the ldwer end of the liner shaftso as tov cause said shaftto rotate with the bowl.

The light constituents of the solution I being'separated pass upwardly inside of the imposed one upon the other, and the stand- I solutiorr'from the supply pipe 19.

2 is provided with a bracket 17 on which the receptacle 16 rests, as shown in Fig. 1, the receiving receptacle l0 bein provided with a float 18 that controls the ow of the When itj'is 'desired to clean the'pa rts of the separator, the receptacles 10, let and '16- are removed'and thetop or'cover B ofthe, bowl is then unscrewed so as to enable the liner-and cone to. be removed. In view. of the fact that the cooperating surfaces or contacting faces between the cover B and thecone, and between thecone and the liner shaft, are perfectly smooth, the parts can be removed quicker and can be cleaned more thoroughly than if said parts were connected together by screw threads as in the separators now in general use.

As it-is necessary to have the bowl perfectly level I have constructed the standard 2 in such a manner that it can be adjusted relatively to the stationary base 1. In the form of my invention shown, in Fig. 1, the base 1 is provided with an iapp'roximately ball-shaped projection 20 "that fits in a socket on the standard 2, said standardconsisting of two or more sectioths that are held together by bolts 21 which cause the standard to firmly clamp the ball-shaped projection 20 on the base and thus lock the standard in position. In the form' of my invention illustrated in Fig. 3 the base 1 is provided with a concaved' seat and the standard 2 is I provided with a convexed lower end that fits in said seat, the standard being clamped to the base by means .of-a bolt 21". By constructing the standardlin this-manner it a very simple matter toadjust itsso as to make thebowl perfectly-level- Qne feature of my-pre sent-inventiqnlwhich I believe is broadly newin centrifugal sepa- .ra

more chambers for receiving and collecting the constituents: of com aratively greate specific gravit In the orm of mylinven tion illustrate in Fig. 1 the bowl A ispro-i' vided with an annular chamber that su rrounds the lower portion ofthe bowl, thewall of the bowl being providedwith aplupermit the heavier constituents of the. tolution to enter said chamber when the bowl 1s rotated. When the separator is being used for separating cream from milk, the bacterium in the milk, which is of greater specific gravit than the 'milk, willbe thrownbyl centri 'ugal force through the slots '22 intlfe rality of'vertically disposed slots 22 that bowl and lodge in the chamber E, and the milk and cream will be forced upwardl into the rece tacles 16- .and 14, respective y,, as previously described. I prefergto form, the slots 22 tapered or approximately, wedge shaped in cross section, as shown in "Fig. 2,

so that each slot will have a comparatively v wide entrance and 'a narrow outlet which overcomes any tendency of theparticles to escape from the slots back into the. bowl after they have once entered the slots. I If desired, the bowl can have a plurality ofreceiving chambers E and E, as shown in Figs/7 and 10, so as to more finely grade the solution or eflect a more thorough 'separation thereof,the heaviest constituents, of

stituents ofv any suspended solution onefrom another. I have herein shown the chamber E formed by ana )p'roximately cup-shaped member-23 that orms the bottom of the bowl A, the sides of the bowl being formed by. an open-ended cylinder that PIOJGCCS into the member 23 and rests on the bottom thereof. Said cylinder :is of less diameter than the member 23 so that a chamber E will be formed between said parts. The upper end .ofthe' member 23 is screwed into aiflangew '24 on the exterior of said cylinder, as shown clearly in Fig. 1;:ss as to enable said parts to be separatedwhenit is desired to remove the substance that has collected in the cham ber of providing the liner shaft D with laterall projecting arms 11,"as shown inPEigsnLa, 11 2, the bowl A. can be provided on its interior with arms llrthat project inv wardly' -i toward: the shaft D. as shown i'n 4 providing the bowl with onegorf other form of bowl in which vertically dis-' posed arms; 11 project upwardly from the bottom of the bowl, said .arms being arranged in rows that extend radially from the longitudinal center of the bowl, as shown in Fig. 8. In the bowl. shown in Fig. 5 the solution is introduced into the lower end of the bowl through an opening 25 in the bottom thereof instead of being introduced through a pipe or hollow shaft that projects through the cover of the bowl. The bowl shown in Figs. 6 and 9 is also provided in its bottom with an o ening 25 through which the solution is intro uced and instead of having the arms 11 connected directly to the bowl said arms are connected to a sleeve 26 which is slipped inside of the bowl, the arms projecting inwardly from said sleeve toward the longitudinal axis of the bowl.
