' For a full description ofthe-inventionand:

themerits thereof and also to acquire a knowledge of the details of. construction of the means for effecting the result reference 18 to be had to the following description and accompanyingdrawin s,'in whichi 3 Figure 1 1s a "vertlca sectional view show lied t ereto. Fig. 2- is. a view similar to i 3 embodying a modification. Fig.3 is

a etail perspective view of a set of coilssuch asare'usedin the construction in Fig. 1. Fig. 4 1s a perspective view similar to Fig. '3, the set of colls illustrated being of the form used in the construction in Fi 2. Fig. 5 is a brokensectional view embodying a further modlfication.

Corresponding and like parts are referred.

to in the followin description and indicated in all the views 0 the drawings bythe same a reference characters.

Referring to the drawings, the numeral l indicates the bowl of a centrifugal'separator,

:said bowl being of any'convent onal and approved construction at present in use. The feed-tube 2 enters the bowl 1 and is provided at its lower portion with the lateral outlets 3,

as is pustomary. The separating-bowl 1 is provided at its upper portion with the "skimmed-milk outlet-passages Y 4 and the cream-outlet 5 above the passages 4.

Arranged within the body of the bowl 1 are, a plurality of coils 6 6 6* 6, &c., arran ed in sets, said sets of coils being arrange one arator-bowl havingthe invention ap- Specification of Letters Patent. 1 Patented March 13, 1906; Application filed April 14, 1905. strain. 255,585.

' within the other and concentrically of the tube 2, through which the liquid is fed into i the bowl. The term coils as used herein is designed'as a broad or generic term applying to rings, coils, or similar parts arranged and combined in a manner herein specified for accomplishing the functionsof the inven,

tion. In the preferred form of the invention the sets of'coils'6 6', &c., are arranged in spacedrelation and the various coils of each set are in'vertical alinement, so that vertical passages coils. Further, the coils of, each set of coils which are in superposed relation are spaced from each other to a certain extent, the-ad- 7 are formed between'the sets of 6s .jacent 0011s of the sets of coils 6 6 6 ,,&c.,b'e- 4 the various sets-of coils aforesaid. The coils of each set of coils 6 6 6 &c., are preferably attached together by means of vertical bars 9, curved to form hooks at opposite ends to engage over the uppermost and lowermost coil of each set The bars 9 are preferably attached exterior-of the sets of coils,- and when the various sets are arranged one within the other said bars 9 form spacin tween the setsof coils toffacilitate the pro visionof the passages 7 and at the same time assist in promoting the separation of the cream-globules from the wateryor skimmed liquid. made of independent or separate coils, if de sired, within'the contemplation of the invention, though the constructiom above menfrom the central to the o'utermost'portion of members be- The sets of coils 6 .6, & c., may be v tioned is'preferably utilized.

The number of sets. of

coils employed is immaterial, since such num-,.

The operation and advantages of the invention will now be noted. .As the bowl 1 revolves in the customary manner the liquid tions of the liquid. However, it will be seen that thephir'ality of passages 2 will permit the cream-globules to separate at various points, and the coils of. the various sets of coils in the arrangement described greatly facilitate the separation. of the cream-globules', so that the latter are free to rise in a manner which will .be apparent to those 'versed in'this art.

'Figs.l2 and 4 illustrate a modification of the invention in which the laterally-alined coils are arran ed in sets, (indicated at 10 1O 10 10, &c.',) t e sets being placed one above the other with the coils thereof in vertical and lateral alinement. The sets of coils 10 10*, &c., howeverfare preferably made of conical form, the materialfrom which they are constructed being wound helically instead of spirally, as indicated in connection with the construction of Figs. 1- and 2.

p The coils of the sets 10 10*, &c., are secured to ether in any suitable way, and the s aced re ation of the coilsof each set and of t e sets of coils clined downwar is substantially the same as indicated with reference to the-preferred construction before described. Theform of the sets of coils 10 10, &c., is such that the passages 1*, Whichextend with the (passages 8 inFig. 1, are inly instead of horizontally. The above is advantageous .under certam conditions in separating the cream-globules I from the milk, t

e liquid being forced downwardly instead of horizontally as it passes through the passages *8. The assagesv "F in Fig. 2 are the same as those in icated at 7 in Fig. 1.

sages 8* will incline upwardly instea of certain conditions alsoi The sets of coils 10 10?, &c., may be reversed, as shown in Fig. 5, so that the as 7 l-Ia\ ing thus described the invention, what is claimed as new is 1. In a centrifugal cream-separator, the combination of a separating-bowl, and spaced inner and outer coils in said bowl.

2. In a centrifugal cream-se arator, the combination of a a separating-bow and spaced sets of inner and outer superposed coils-in said bowl, the coils of each set being spaced from each other.

3.- In a centrifugal cream-separator, the combination of a separating-bowl, and sets of inner and outer spaced coils in said bowl, the coils of each set being of approximately circular formation in cross-section.

4. In a centrifugalcreamseparator, the combination of a separating-bowl, and sets of inner and outer coils in said bowl, the sets of coils being so arranged as to form outflowpassages therebetween.

5. In a centrifugal cream-separator, the

combination of a separating-bowl, and sets of inner and outer coils in said bowl, the sets of coils being so arran ed as to form vertical outflow spaces there etween, the relative ositions of the coils of each set being such'as 0 form lateral outflow spaces or passages.

6. In a centrifugal cream-separator, the combination of a separating-bowl,- and sets of inner and outer coils in said bowl, the sets of coils being so arran ed as to form vertical outflow spaces there etween, the relative positions of the. coils of each set with regard to the coils of the next adjacentset, being such as to form straight lateral outflow-passages. q

7. In a centrifugal cream-separator, the combination of a separating-bowl, .and sets 7 of inner and outer concentric spaced coils in sald bowl.

8. In a centrifugal cream-separator. the combination of ,a 4 separating bowl, sets of inner and outer concentric spaced coils in said bowl, and a-feed-tube entering the bowl centrally of the innermost set of coils.

:9. In a centrifugal cream-separator, the

combination of a separating-bowl, sets of coils in said bowl, and spacing means between the sets of coils.

10} In a centrifugal cream-separator, the combination of a separatingbowl,-and sets of coils in said bowl, each set being made of a single length of material.

11. In a centrifugal cream-separator, the combination of a separating-bowl, sets' of coils disposed in the bowl, and bars connecting the coils of each set.
