13e it known that I, WILLIAM CHARLES MOORE, a citizen oi' the United States, residing at New Iberia, in `the parish of Iberia and State of Louisiana, have invented certain newv and useful Improvements in Centrifugal Machines; and I do declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention rela-tes to improvements in centrifugal machines for separating molasses f rom sugar, and more particularly to the rotary baskets thereof; and it has for its general object to 'provide a rotary basket for a centrifugal machine embodying such a oonstruction that the separation and escape of the molasses from the sugar will be materially accelerated, and in consequence the time necessary to separate each charge will be shortened and the capacity of the machine Will be increased, and this without materially increasing the cost of the rotary basket.

Other objects and advantages of the invention will be fully understood from the following description and claims when taken in conjunction with the accom pan ying drawings, in Which- Figure l is a detail diametrical section of so much of a centrifugal liquid-separator as is necessary to illustrate my invention. Fig. is an enlarged detail section showing my improvements. Fig. 3 is avieiv of the fora minated and sectional annulus of my improvements removed. Fig. 4. is an inverted plan view of the sectional block in which the guide- Ways are formed. Figs. 5 and 6 are similar views of modified forms of bloeksections- 7 is a detail perspective view of a blocksection and one of the segments of the foralninated annulus connected together. Fig. 8 is an enlarged detail section illustrating a modific-ation.

Referring by numerals to said d rawings,and more particularly to Figs. l to '7 thereof, l indicates the casing of a centrifugal machine, which is designed to receive the molasses separated from the sugar and is provided with an outlet 2 for the same, and 3 indicates a eentral upright shaft, both of which may be and preferably are of the ordinary construction,

and 4. indicates the rotary basket, which is iiXed to and is designed to turn with the shaft This basket 4, like the ordinary basket, has'tlie imperforate bottom 5, the inner and outer'foraminated shells G and 7, and the interposed gauze S, to permit the outward passage of molasses and retain the sugar, and

' the inwardly-directed annular portion 9, de-

sign ed to prevent the sugar and molasses from being thrown out of the basket by centrifugal action.

Asis Well known to those experienced in operatin g centrifugal separators, the rapid rotation of the basket causes the Wet sugar or massquete to distribute or spread itself evenly over the side Wall of the basket, and when the sugar is of low grade the molasses will not pass through the sugar freely, but on the other hand often forms in a layer of varying thickness on the inner side of the sugar until gradually forced through the sugar into the casing l. This prolonge the process of separation and materially reduces the capacity of the machine and is objectionable for that reason. The rapid rotation of the basket 4. also causes the sugar and the molasses to ascend the side of the same, and I propose to take advantage of such ascension of the sugar and molasses to accelerate the separation of the same and thereby reduce the time necessary to separate a charge and increase the capacity of the machine. To this end I provide the block 10 and the foraminated annulns or plate ll, and preferably connect gauze 13 tothe under side of the plate l1. The block .lO may be in one piece or a plurality of segments, as shown in Fig. 4, and it is beveled on its upper side to conform to the in Wardly-directed portion 9 of the basket 4, beneath which it is arranged and suitably secured, as illustrated. This block l0 is provided in its under side with grooves l2, which may be radially disposed, as shown in Figs. l to 4, tangentially disposed, as shown in Fic. 5, or curved, as shown in Fig. 6, and are preferably closed at their inner ends by a strip let, increased in Width toward their outer ends, 'as shown, so as to permit the molasses to flow more freely through such ends and thence out of the basket through the upper perforations in the outer shell 7. The foraininated annulus or plate 1l. and the gauze 13, connected ICO molasses to pass to the grooves 12 of said block 10 and check the passage of the sugar, asrwill be hereinafter more fully explained.

The baskets of centrifugal machines: ats

present in use have inwardly-directed portions 9 for the purpose before described, and the block 10- and annulus 11 are: formed im segments, as described, in order that they may be readily placed and secured in the' baskets. When, however, my im rovements are.

embodied in anew machine, t ebl'ock l0 and4 annulus 1ly may be respectivelyformed` in; one,` piece. The block 10, when formed; in@ one piece or of a plurality of segments, servesr in conjunction with thel inwardlydirected' por-1y tion 9 of the: basket', to form an:` inwardly-directed flange 9a, the grooves. 12in the block' l0 being at the underside of said flange, as shown. When desirable, the; inwardly:div4 rected flange of the basketmay be fernred one piece, as shown in Fig. 8. This flange 9? is provided inits. under sidewith groovesrla, which communicate at their outer ends,y the upper perforations in the*y outer shellll; Theforaminated annulus er plate l1 andthe ganze 13', connected thereto, are.also,employedl in conjunction with the flange 9h, they being arranged and suitably secured immediately below the grooved under side of the lian-gez, as shown.

In the practical operation: of thekmaeli-inef ket, and the latter will takev through the apertures of the plate. 11,. the grooves: of the inwardly-directed liange, and; the apertures of the shell 7, and into the casinglf, while, the sugar willberetained Within thebasketl by the plate lil.. In virtue of this and the fact) that; a. portion ofi the:v molasses' will also be forced through the side of the basket it will` be seen that a charge will be quickly separated, and that consequently the capacity of the machine will bematerially increased. f Itzwilll alsebeiappreciated that my improve ments are, very simple and do not add matefinally tothey cost of a centrifugal machine, and that the improvements may be added to dmachines at present in use, as well as ernbodied in new machines.r
