Patented Feb. 6, 1912.

To all lwhom it may concern Be it known that I, GUsfrAr M. ANDER- soN, a citizen of the, United States of America, anda resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Adjustcentrifugal cream separators, and the object g clogging creamy-exit device.
of my improvement is to provide for'the bowl of such a separator a regulable nonclogging cream-exit, formed of-communicating channels of different radial Widths'withV the inner wall of the entrance channel approaching more nearly the axis ofthe bowl than the nearest part of the inner wall of the other or exit channel, a movable dam beingv furnished -to intercept adjustably the communication of said channels and lying partly within the interior-hollow' of each channel. rThis object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the following drawings.
This application is a division of application Serial Number 502,505, filedby me on June 16th, 1909.
In the drawings: Figure 1 is a central vertical axial section of the bowl of a centrifugal cream separator, showing in central vertical'section my improved regulable non- Fig. 2 isan upper plan view of the cream-exit head `and a broken portion of the diaphragm on which it is mounted. Fig. 3 is a vertical central section of the structures shown in Fig. 2, taken through the axis of the communicating channels leading to the cream-exit. Fig. 4 is a side elevation of ythe structure shown in Fig. 2. Fig. 5 is an enlarged detail diagrammatic view of the communicating cream-exit channels and their intercepting adjustable dam, parts being Vshown broken away and the radially-varying density of the separated cream lindicated therein by dotted shading.
The bowl of the separator shown is in two portions, the body 11 anda removable base 15, the spindle 14 being axially united to the latter. The contacting parts of the body 11 and the base 15are provided at their .line of junction with a rubber gasket 16 set in an annular groove in the base to revent leakage. The upper end of the spin le ro- ]ects above the base 15 in the form of a oss which -is iitted within the hollow lower end of a milk inlet-tube 1, but is grooved to afford channels which communicate with the radially-directed milk delivery oriiices 13. The tube 1 is integralwith said baseand concentric with the axis of the bowl. 'When said base and tube have been fitted within said bowl, a lock-nut 2 serves to secure the upper end of the tube in its seat in the contracted top of the bowl. A frustum-supporter 8, in the form of a hollow cylinder, is removablyv fitted over the inlet-tube 1, and is provided on its exterior surface with a plurality of spaced apart low vertical ridges.
The lwer end vof the cylinder 8 is secured y to and communicates with a concentric hollow frustum 24, whose upper edges are bent inwardly to approach the cylinder horizontally, while the horizontal portion is pro? vided with a plurality of slots 12. The lower part of the frustum 24. is supported on the base of the bowl`and is fitted closely but removably about a raised portion thereof.
The liner of the bowl is vcomposed of a pile of separating plates each in the form of a hollow frustum 9, with their inner portions bent to extend horizontally inwardly toward the axis of the bowl. The inner edges of said frusta are formed with projections separated by spaces 12, the latter coincident with and lying vertically above the like slots in the frustum 24 so as to register therewith and thus afford uninterrupted channels for the passage therethrough of milk and cream.
The ridges on the cylinder 8 keep the frusta 9 in the same registering vertical alinement.
The numeral 23 desi hates a hollow inner cone within and spac away from the conical head of the bowl 11, and having a hollow upwardly directed cylindrical extension having a thimble 26 fitted therein. The skimmed milk passes between the cone 23 and the bowl-head linto the milk-exit 27. The cream passes upward inside of the cone 23 and into a tubular channel which is formed of two arts, the entrance part 7 in the tube 17 being of larger area with its inner wall extending nearer to the axis -of the bowl than the inner wall of the communicating part 6 in the tube 18. The upper lpart of the channel 6' is bent or curved out- Y cream-exit or outlet, it will be seen that it depicts the cream-screw or adjustable dam 5 as partly moved inward toward the axis of the bowl within the outlet at the line of junction of the channels 6 and 7. In this position it so restricts the outer portion of the outletas to prevent the issue of the most diluted or outer stratum of the cream. For
purposes of convenience, I have re resented the cream in the channel 7 as divlded into three strata, a, band c, of specific gravities increasing from a to c. It is, of course, obvious that there are no such exact divisions between strata for-the cream varies imperceptibly inits density radially outward from the bowls axis under the. influence of centrifugal force, but as an illustration the definition of strata is convenient. The function, therefore, of the screw 5 is to more or less dam the issuing cream to correspondingly vary its amount of dilution with milk, since if the' screw be not intruded into the current of the stratum, c, the skimmed cream will .have a maximum of dilutionwith the milk yet unseparated therefrom in the outer zone of the cream wall corresponding with this stratum. If moved radially inward to intercept the stratum c, the skimmed cream will be of less specific gravi-ty including the strata b and c, but if the dam be brought inwardly still more, `only the cream of llghtest specific gravity in the stratum a will be skimmed. Now, the object of my improvement in making the cream outlet communicating channels 6 and 7 of different areas with the inner wall of the channel 7 nearer the axis of the bowl, is this; to afford a greater clearance for the issuing cream to prevent clotting of the cream therein when cold or when exceptionally rich. Even in the event that when cold some of the richest cream may clot upon the inner walls of the munication of the channels 6 and 7 affords a 65 erfect control of the communication, the
vinner end of the screw being movable partly inthe upper end of the channel 7 as well as partly 1n the lower end of the channel 6 of -lesser area.v The wider channel 7 also permits of the recession of the cream zone 1nward toward the bowls axis farther than in some liners, thereby permitting a surer control of the issuing cream, by giving better clearance to the thickest partof the cream. While the outer limit of the inner walls of both the channels 6 and 7 is the same, the
widening of the channel 7 ermits of a radially wider cream zone eing skimmed which ives the operator a wider choice o regulation of the dilution of the' cream in sklmming.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:
. 1. In a cream outlet for a separator bowl, the combination of two channels for the issuing cream, of which one channel is wider radially than the other from the axis of the bowl, and a movable dam located partly in the large and partly in the small channel adapted to variably cut off the ilow of cream at the communicating parts of said channels.
2. In a cream outlet for a`separator bowl, the combination of two channels for the issuin cream, of which the entrance channel is wlder than the other channel in a lane extending radially from the axis o the bowl, and said entrance channel emptying into the other channel, and a movable dam located partly inthe wider and partly in the narrower channel adapted to variably control the dilution of the cream passing thereby.
3. In a cream outlet for a separator bowl, the combination of two communicating channels for the issuing cream of which the inner or entrance channel is the wider radially from the axis of the bowl, the outer limits of the inner walls of both being the same but the inner limit of the entrance or larger channel approaching more closely the axis of the bowl than the inner limit of the other channel, and a movable dam located partly within the larger and within the smaller channel at their place of communication.
