Application filed lanuatyt, 1909. Serial No. 470,818; v
separable superposed 1i uid subdividers \vithin the bowl are definite y assembled, adjusted and retained in concentricity, and all held together in a stable unitary. structure independently of the bowl or other parts of the separator, so that it may be removed from the bowl and inserted therein as such structure, and when removed the component arts may readily be released and separated tor cleaning or repairing.
The detailed construction" is set forth in the description following, in connection. with the accompanying drawings, wherein--- liigurel 1s a vertical, diametrieal section "of the bowl with the series of superposed sub:
dividers and their adjusting and retaining devices assembled therein; Fig. 2, a plan of the top late of the series; Fig. 3% isn )lan of, one 0 the intermediate sululividers oi the series; Fig. 4 is an elevation of the lowest subdivider with two retaining; rods; Fi 5 is a detail of a portion ol' the. upper plate showing, in vertical, section one of the rodsecuring nuts with a tubular extension thereon; Fig. 6 is cross-sections on line 6- 6 oi the two retaining rods illustratedin Fig. 4.
Designating the several parts of the appuratus illustrated in the drawings by reference letters, Bis the bowl; 3, the sulnlividers; s the top plate and s the lower plate of the series.
ilbarethc adjusting and retaining rods for the sululividers, one of which, it, may be made dill'erent in cross-section from anyof the others for the purpose ol'.'.le(initely determining the relative cirrumierential position of the several subdividers by means of a notch in. each having a shape corres uuuling to that ol' the cross-section of the rod. This dill'orenee in cross-section of the rods also constitutes an unsymmetrical arrangement of their peripheries, and the same result may be obtained by locatiln rods of similar crosssection unsymmetricall y, either cireumfcrentiall or radially, in respect to the axis of the bow Only two such rods are shown, but any other convenient number may be employed, and all may be permanently secured to the lower plate s at p, and t0 the upper plate 8 by nuts N, which may be readily attached to and released from the screwthreaded ortions t at the upper ends of the rods. XV ien the series of subdividers are properly assembled about the rods R and securely held by the nuts N, they become a stable unitary structure independent of any support from the bowl, and can beinserted therein and removed therefrom 'Without any liability of disarrangement or separation; and at the same time when thfieomposite structure is removed, the parts may be readily separated by unscrewing the nuts from the rods.
C is the cover which fits into an annular rabbet in the top of the bowl where a packingring is inserted, and this cover is held firmly in place by ared I) provided with a collar 0 to rest upon the top of the cover, which rod extends (lo'wnthrough the annular openings in the subdlvidersand s screwed into a socket f in the bottoinof thebowl. A
cream outlet G is provided in the cover, and in'order that it may always be located in the same position in relation to the top plate 8, an upwardly projecting stud H is secured upon that )late and a socket for't'he stud is formed intlie under side of the cover. Skimmilk outlets I are made in thebottom of the bowl, and to provide a passage for the skimmilk to those outlets between the bottom of the bowl and the lower plate 3",. short projections M are provided on the underside of that plate.
The several subdividers herein illustrated are constructed substantially like those shown in my prior patent No. 806,346 of December 5 1905, having a Hat annular perforotcd plate is, upon both sides of which a series of curved blades ore secured, and when the subdividers are superposed the op posed blades ill interlock.
In the internal periphery of the annular plate ol each sululivuler, notches .lJ are formed, eorrespoiuling in location to that of the several rods it, it, in -1'elnliou to the axis of the bowl, and in shape to that ol the crosssection of the respective rods; thus when the sulnlividcrs are being assembled the position of each in relation to the others can readily same order in which they were originallyfitted, and toinsure this, each annular plate is provided with a small projection 1/) beyond the circle of its internal periphery, and upon the upper side of this n'ojection a number, or other designating or( inal, is placed, which will indicate the vertical )osition of each subdivider in relation to the others of the series. For ractical results two of these adjusting ant retaining rods R for the subdividers are found sullicient, but as pre viously stated more may be used if desired.
The two rods will, when the corresponding notches of the subdivider plates are placed over them, insure the concentricity-ot' the vwhole series, and retain them in such posi tion. The nuts N are of novel construction and very convenient in this connection. Each nut is rovided with a tubular extension 0 which oosely fits in a hole in the upper plate 8. The lower ends of these tubular extensions are' flared outward at q and serve a double purpose, first, the flaring lip prevents the nut from beingl accidentally removed from its socket in, e plate and being mislaid or lost, and second, theflaring 0 on end ofthe tube makes it very easy to nd the upper and of the rods B when the upperplate s is laced u on the top of the series of sub divi ers; in act, the operation is substantially automatic, for when the u perplate is placed in pro er position upon t 1e top of the io-series, the to ular extensions of the nuts of necessity 'slide over the ends of the'retaining rods.
As illustrated, the screw-threaded portion 2' of the upper end of the rod R is smaller than that of the other rod, to serve as a means to indicate the proper circumferential,
is secured upon the interior of the bowl, and
a corresponding groove c is formed in the outer periphery of each subdivider to slide over and'engage' the rib a when the series of subdivid'ers are inserted within the bowl. 615 I I claun:-
