Application filed July 31,1907. Serial No. 386,445.

To all whom it may concern:

Be it known that LWILLIAu L. DrLLnA'v,

-a citizen of the United States,residing at Ko homo, in the county of Howard and State of Indiana, haveinvented certain new and useful Improvements in Cream-Separators, of which the followilu is a Specification.

This invention rc ates' to centrifugal cream separators, and consists essentially of an improved liner for the bowl, whereby separation of the constituents of the whole milk is effected, and a lpeculiar compensating bearing to take up t c great vibration incidental to the operation of the bowl when rotated, and which is adjustable by a special connection between the stand of the machine and the casing of the bowl. I g

The invention also involves novel details of construction and for a full understanding of the various novel features, reference is to be had to the following description and the accompanying drawings, in which:

Figure 1 is a vertical sectional view of a separator embodying the essential features of the resent invention. Fig. 2 is a sectional view on thelinc 22 of Fig. 1. Fig. 3

'is a side view of the liner forming a part of the invention, partly in section. Fig. l-is a vertical sectional view of the bearing for the bowl spindle. Y

Corresponding and like parts are referred to in all the views of the drawings, and indicated by the same reference characters.

In carrying out the invention a machineconstructed .in accordance therewith is comprised of the usual general arrangement of is peculiarly mounted on the standard 1.-

Said head comprises an approximately circular body having a cover 2 removably mounted at one side thereof, said cover being form ed lwith an integral arm 3 pr0\dded with .a'verti'ealbearing 4 at its inner end. A crank shaft 5 1s IHOUIltCClJlI a horizontal.

bearing 6 provided in the upper ortion of the head 2, a suitable crank hand e 7 being applied to the outer end of the shaft 5 md a Jorge bevel gee-r8 being secured to the inner end of'snid shaft. The bevel ear 8 meshes witha bevel pinion 9, the latter eingapart of a clutch element 10 wlnch cooperates with a second clutch element 11 to provide a ball ratchet mechanism, the balls being indicated at 12. The pinion 9 is adapted to be actuated on operation of the shaft 5 in an obvious manner and the gearing mounted in the head 2 is designed to effect rotation of a vertical shaft 13 which is arranged within the standard 1 and thenpper end of which is journaled' in the bearing 4 of the arm 3 before described.

The pinion 9 is loosely mounted upon theshaft 13 and the ratchet mechanism cooperatlng with saidpinion permits of continued rotation of the shaft even though the crank' handle 7-is stationary.

The head 2 is mounted on the standard 1 but is adjustable relative thereto in order that the osition of the crank handle 7 may be arjusted or.

varied according to the convenience of the operator. For the above purpose the upper portionof the standard 1 is I-Cul '6d in the ower'portion of the head 2 and the latter is attached to the standard by means of a set screw 14 or analogous fastening. It will be apparent that the mounting of the head 2 is suchthat it may be rotated and-fixed in'an adjusted position with readiness. Upon the lower end of the shaft 13 which extends into the base of the su ort 01: st and A is'mounted a gear 15, a suite is adjustable bearing 16 being provided to receive the lower ex tremity of said shaft. The gear 15 meshes with a pinion 17 carried by a second gear 18 which-1s journaled in suitable bearings 19 clearlyshown. The gear 18 engages a pinion 20 formed upon the lower end of the spindle 21 which carries the se arator bowl 22, the spindle 21 being integra with the bottom of said bowl.

The bowl 22 is mounted for rotary move ment in the customary manner in a peculiar bearin which will be more clearly described hereinafter. A casing 22, removably mounted upon its bottom 24, surroundsthe bowl 22. The bottom 24 of the cosin 23 is formed with an opening through which the spindle 21 passes, and projecting downwardly from said bott'ou is an annular internally threaded llange or collar 2-5 which is screwed upon-the upper end of a neck or not only detachably tubule projection 26 cictc'ndiir upwardly from t e base A of the stand w iich carries the se arator mechanism. The projection ZS-is ormed with an internal shoulder 27 having an opening through which the spindle .21 passes and formed with a'recess 28 in its upper side. Y

Arranged between the shoulder 27 of the projection 26 and the bottom of the bowl 19 casing 23 is a compensating bearing for the spindle 21, said bearin being adjustable by relative adjustment or the bottom of the bowl casing and the projection 26, such adjustment being allort ed ,by the threaded connection between these parts. The coinpensating bearing above mentioned comprises a sleeve 29, snu ly receiving the spindle 21 therein, and springs, 30 and 31. Intermediate of its ends the sleeve 29 is formed with an integral flange 32 in tlie inper and lower sides of which are provide circular grooves 33 in which theadjacent ends of the springs and 31 arereceived. The low-er end of the 2,5 spring 3i is received in the recess 28 of the s oulder 27, andthe upper end of the spring 30 is received in a recess 34 formed in'the bottom .24 of the casing 23 and at the )eriphery of the o enin of said bottom. 39 he sleeve. 29 is opsmafier diameter than the opening in the bottom 24 of casing 23 and passes through said openingl It will be apparent that the'arrangement of the parts oi the bearing just described is 35 such that the great vibration incidental'to the rotation of the bowl in the actual operation of the machine is fully absorbed, and strain and jar upon the supporting means for the bowl are reduced to a minimum. Furthermore the construction of the supporting parts of the compensating bearing, whereby such parts also form supporting means'for the bowl is .extrcmely advantageous in that adjustment of said parts may be readily effected to correspondingly adjust the springs 30 and 31 whereby the tension of sa d springs may be increased or decreased as may be necessary under actual conditions of service. The casing23 sursc rounding the bowl 22 is made of light metal and rests upon an annular shoulder formed in the outer portion of. the. bottom 24, being readily removable from such position.

Within the bowl 22 is arranged a peculiar form of liner, the special construction of which is designed to increase the efiiciency of the machine with regard to the separation of the elements of the liquid operated upon thereby. The liner is composed of a central stem 35 of tubular form, the lower end of which is' internally threaded to receive a threaded boss 36 which is integrally formed with the bottom of the bowl 22. The tubu-. lar stem35 is'tormcd with integral radially curved plates or wings 36, the outer edge cooperating coileda spout 47. 7

pan 47 is provided, the latter being su 120 portions of which substantially tit'thc inner sideof th'e bowl 22. The dates or wings 36 arqintegrally formed at the lower portions thereof with the stem or tubular member 35, the inner edge portions of said plates being 'spaccd nearly throughout the length thereof from the members 35. In other words the plates 36 are so formed as to provide an annular space'between their inner edges and the tubular stem or member 35, said space comprising an upward passage for the cream as the latter is separated from the skim? milk. Between the several plates 36 of the liner are arranged at intervals, and vertically spaced from each other, a number of down- 3 wardly inclining webs 37, sets of the webs being in parallei and substantially horizontal planes and having the inner edges thereof spaced from the tubular member 35,

or llusl. with the inner edges of the platesSG. 35 The several webs 37 com rise transverse partitions between the bhu es or wings 36- and said partitions are straight in cross section or from. the outer to the inner edges thereof. Arranged at the up er portion of 9c the bowl 22 is the cover there or, said cover comprising inner and outer sections 38 and 39 respectively. The outer section consists of a body receiving the upper end of the bowl and having a gasket 40 interposed bc tween it and the upper edge of said bowl.- The inner section 38 of the cover alsoconsists of a body portion the same being spaced at its up )er side from thecorresponding portion 0 the outer section of the cover to provide a passage 41 for the skim-milk which asses through a plurality of openings 42 coated near the ed e portion of said inner cover section. Each of the cover sections has a tubular extension at its upper portion, the extension 33 of the inner section b ing spaced a-portion of its length from the extension 39 of the section 39, as shown at 41*, said space forming a continuation of the s ace or passage 41, and permitting the shim-milk to pass from t 1e passage 41 through outlet openin 43 in the outer cover section. A cream tn 0 44 is applied to the inner cover section 38 and conveys the cream passing upwardly from the space just surroundin the stem 35, to the cream outlet 45. Mounts upon the top of the casing .23 for the bowl 22 is s rill; pan 46 from which leads In a similar manner acream ported upon the pan -16 ahd receiving t c. cream from the cream outiit 4-3, A suit:- able spout 48 leads oi? irom'thc pan 47. A cover 49 is provided for thc'pan47, cnd'h, float cup 50 is su in a conventional manner.

Itwill be undemtood that the stand for the separating mechanisni'beforc described will have a suitable braeke tltntio carry the milk receptacle-and may also ve a. cream reooorted upon said cover, 12 5,

latter having lateral openings 35 at its lower portion. The milk passes through the openings 35 and through vertical openings 37 in the lowermost webs 37 as well aspassing into the space between the member 35 and the bowl by passage around the lower edges of the lowermost webs. The spindle 21 of the bowl 212 is provided with an adjustable bearing at its lower end as shown in the drawings and adjustment of said spindle may be readily effected in the same manner as such adjustment may be performed in outer section 39.

regard to the shaft 13 and the gear 18.

'The advantages of 'the several features of construction hereinbefore set forth will be obvious from the foregoing description. A ring nut 51 is screwed upon the upper extremity of the tubular member 35 of the liner and is arranged above the sections of the cover of the bowl 22. Said nut-engages the tubular extensions 39*" of section 39 and revents displacement thereof from the owl and leakage of liquid therefrom at the outer flange 52 of the cover 39.

It will be observed that the upper portion 38 of the inner cover section has a snug slid ing fit within the upper portion 39 of the outer section. Themilk holes 42 are located in the section 33 and the outlet holes 43 in the Likewise the cream tube 44 is carried by he inner section and the upper end thereof must register'with the single outlet hole -15. In order, therefore, to insure pro er registration of these parts I provide a s ide groove u )on the inner surface of the extension 39 an into which the tube 44 is received, the tube projecting sufficiently beyond the outer surface of the upper portion 38 to effect this result, the hole 45 being at the upper end of the said roove.

It will be understood that the liner which -com )rises the wings 36 rotates within the Patent ofthe United States, is:
