-vide an apparatus of this sort in which there willbegno tendency of the disks tovarytheir distance with respect to each other, whereby form' and the proper and smooth running of New York, in the State ofNew York, have invented certainznew and .useful Improvements in Apparatus for TreatingMilk and other Liquids, of which, the following is-a specification, reference'ibeing had to the 1 3.0--

companying d i wformingmappart hereof. r w a cut No. 917,008, dated April 6,-. 1909, in whichtype of {machines the liquid to be relative movement'in respect to each other;

The main object of the invention is topros the treatment of the liquid may remain u'nithe machine continue tunafiected. .For I have discovered that in some machines having the rotating disks, 'ap'artial vacuum is produced between the disks by the centrifugal action, which tends to draw the disks'together; and that this not only interferes with the smooth running of the machines,

but the variation ofthe dlstance between thefacesof the disks produces considerable dif;

chines. a

One embodiment "of the inventionl by means' of which the foregoing objections may be overcomeis shown the accompanying drawingsinwhich,

Figure 1 is a view 'thereofin elevation. Fig. 2 is a view in central vertical section, with the funnel and motor omitted, and, Figs. 3 and 4 are plan views of the rotating member as seen respectively from the irregular planes indicated by the lines 33 and ls-4 in Fig. 2. a In the case of the present embodiment,

there are two sets of disks with opposed roughened faces, as the rotating member a resents a roughened face to each side-memher I) of its inclosing casing (Fig. 2). This rotating member has a shaft 0 fastened therein by a set screw (1 and is driven by a e seawe ds 61 Letters latent. J n i c tibn niea iraie jio, 1910. Seria1 N FMSA IB,

her, whence it finds its way into the interior of the rotating member. The latter is formed withradial ductsjg through which a the liquid is caused. to. flow by centrifugal action until it reaohes the periphery of the. a M p i =s rotating. membenwhenceit isdriven, by the The-invention relatesmore particularly to improvements in machines ofthe type shown and described in United States Letters Patliquid behind it, aroundthe edges of said member and back across both faces and between the faces and the flanges b of the casing. These flangesor side-members] are ring-shaped, being secured together, face to face, by bolts h and, as a-single piece, are fastened to asupport i by abracket is. A packing ring m, moreover, is preferably pro-. vided betweenthe abutting surfaces of these members. 'I he inner opposing faces thereof are provided with a large number of small recesses-m. with sharp edges similar to those indicated at 0 on the faces of .the rotating member aeto provide the desired roughening. The milkor other liquid will,t here-- fore, be pushed across the space between these rougheningsupon either side of the rotating member and will be discharged from near the center of the rotating member. A shell 10, surrounds this portion of the mechanism and the treated liquid will bedelivered from an opening or spout at the lower end of said shell. V a

It will be seen that-with the'present ini: provements, there. can be no tendency of the centrifugal action to produce 'a' vacuum bea tween the opposed roughened surfaces and that, hence, there will be no tendency for" these faces to draw together. Moreover, as the pressures on-both .sides'of the-rotating member a; are the: same, the-latter will be perfectly balanced and will always maintain its true position so that a uniform distance between the roughened surfaces, and therefore a uniform action, is always assured.

Besides using the present improvements for emulsifying milk to extract the butter fat therefrom, it may also be used to effect the sterilization of milk and other liquids without destroying any of the nutritive qualities of the milk or'without otherwise detrimentally affecting the same, which, obviously, cannot be done by heating or the usual process of pasteurization.

Various changes may be made inthe present embodiment of the improvements without departing from the spirit of the invention. V

I claim as my invention: I

1. In an apparatus for treating milk and other liquids, the combination of a rotating member, and a casing therefor arranged to form a narrow space with the rotating member on each side thereof, said casing having an opening'through its central portion ad jacent to the rotating member to provide an exit for the treated substance. 7 2; In an apparatus for treating milk an other liquids, the combination of a rotating member formed to" permit liquid to pass through it from center to -periphery, a casing therefor arranged to form a narrow space with the rotating member on each each side thereof, the adjacent faces of the rotating member and casing being roughened and means to permit the treated substance to pass from the central portion of the space between the'members.

4:. In'an apparatus for treatin milk and other liquids, the combination 0 a member formed to'permit liquid to pass'through it from center to periphery, and a casing therefor arranged to form a narrow space with the rotating member on each side thereof, said casing inclosing the periphery of the member, the adjacent faces of the "member and easing being roughened and the member and casing having relative rotary movement therebetween.

5. In an apparatus for treating milk and other liquids the combination of a rotating -member, a casing therefor containing two rings forming a narrow space with the rotating member on each .side thereof and leaving the center of said member exposed.

6. In an apparatus for treating milk and other liquids, the combination of a rotating member formed to'permit liquid toj'pass through it from the center to the'periphery,

a casing therefor containing two rlngs forming a narrow space with the rotating member on each side thereof and leaving thev center of said member exposed.
