rate the same into its constituents and de-- liver the component parts to separate discharge-receptacles In certain industries, as the manufacture of beet-sugar, it is customary to transport solid articles, such as beets, in a body of liquid, such as water, the mixture being allowed to flow through various conduits to the different places in the plant. In lifting the beets from one elevation to anotheras in preparing to send them to the washing-machine, for instanceit has heretofore been customary to employ lifting wheels; but these wheels have either lifted the beets only, requiring the use of other means for removing the water of flotation from the pit, or they have lifted both beets and water and delivered the same to the washing-machine.

My invention enables me to not only lift both the beets and the water from the pit by the use of one wheel, but also to separate the two and deliver the beets to the washing-machine, while the dirty water passes off through a separate conduit.

The preferred form of'apparatus embodying my invention and one modification thereof are illustrated in the accompanying two sheets of drawings, in which Figure 1 is a vertical axial section through the lifting and separating wheel. Fig. 2 is a side elevation of the wheel with parts broken away and showing section through the pit.

Fig. 3 is a horizontal axial section of the wheel and connected apparatus, and Fig. {i isIa side elevation of a modified form of wheel.

Throughout the drawings like referencefigures indicate like parts.

1 represents a pit of proper shape .into which flows a current of water through the conduit 2, the said water carrying a mass of beets or other articles which will float or nearly float therein.

3 is a wheel of necessary diameter having radial spokes and also inclined spokes or braces 3 usually employed to give it stiffness. This wheel has a rim 4 of imperforate material and two annular strips 5 and 6 of the same material, which together form an annular space 7, inclosed on three sides and open on the inner side.

The annular space 7 is divided into a se ries of buckets by a series of partitions 8, and in connection with each partition 8, above or in front of same, is also located a second partition 9, which is perforate to a greater or less I degree.

The wheel 3 is mounted on a shaft 10, journaled in bearings 11 11, and has rigidly attached to it the spur-gear 12, with which meshes the pinion 13 on the driving-shaft 14. On this driving-shaft is mounted the fast pulley 15 and loose pulley 16 in the wellnown manner. a

At the proper elevation. to receive the materials dropped or tipped out of the pockets 8 is the receptacle 17, which in the construction shown in Figs. 1 and 2 would be a conduit prepared to carry away the water discharged into it.

At a proper elevation to receive the articles, such as beets, which rest upon the parti tions 9, but do not pass through them, is 10- cated a receptacle or chute 18, upon which said beets or other articles are discharged and down which they roll to their destination.

It is evident that the partitions or gratings 9 might be continued out to the inner circumference of the annular rings 5 and 6; but in order to leave a larger opening for the admission of the beets or other articles I preferably bend the outer edge of said partitions 9 downwardly, as clearly shown in Fig. 2.

In the modification shown in Fig. 4 the imperforate partitions 8 are given an inclination such as to form pockets which will retain the fluid therein contained until any particular pocket has reached the higher point in the rotation of the wheel, while the perforate partitions 9 are given a less inclination, so that in this case the action would be the reverse and the beets or other articles would be first discharged, while the major portion of. the fluid would be carried on up and discharged into the conduit 17.

. It will be noted that the essential feature of my invention comprises the two series of pockets formed by the partitions 8 and 9, the partitions forming one series of pockets being penetrable to one constituent of the mixture to be operated on by the wheel, but

impenetrable to another constituent, while the partitions forming the other series of pockets are impenetrable to both constituents of said mixture, and also the giving to the partitions forming these pockets different angles of inclination to the radii of the wheel which passes through them--that is to say, the partitions which are to carry and from which are to be delivered the solid particles, or the particles ofcoarser nature, are rendered penetrable to the smaller particles (such as the water globules) of the other material; also, the partitions which are to carry the articles to be discharged at the lower point are approximately parallel to the radii of the Wheel passing through them, while those partitions which are to carry articles which are to be delivered at a higher point are given an inclination to the wheel radii inwardly of the pocket. Thus, looking at Fig. 2, it will be seen that the perforate partitions 9 areinclined considerably to the adjacent spokes 3 of the wheel, while the imperforate partitions 8 are nearly parallel to theeenter line of said spokes.

The operation of my invention is as follows: The fluid in which the beets are immersed passes down through the conduit 2 by gravity into the pit 1. The water and the beets enter the pockets formed in the wheel, and as the same are carried upward by the rotation of the wheel in the direction of the arrow the water is poured out into the conduit 17 with the arrangement shown in Fig. 2, while the beets are retained on the perforate partitions 9 until they have reached the point above the chute 18, when they also roll out onto said chute and are discharged. In this way both the beets and the water are removed from the pit 1 and at the same time separated y In the construction shown in Fig. 4, as before described, the beets held on the perforate partitions 9 are first tipped off the same, while the major part of the water which has run through into the pockets formed by the partitions 8 is retained until it reaches an altitude at which it is discharged into the higher conduit 17. It should be understood,

Jfcourse, that the discharging force acting on both the sets of particles is that produced by the resultant effect of gravity and centrifugal force, so that the point of separation between the two sets of particles is to a certain extent controlled by the speed of rotation of the wheel.

The advantages of my invention comprise the economy in first cost, space, and power resulting from the fact that the same wheel lifts both materials and separates one from the other, thereby avoiding the necessity of using two wheels or of employing additional separating mechanism.

it is evident, of course, that various changes could be made in the details of the construction shown in the drawings without departing from the spirit and scope of my invention so long as the characteristic features and the principle of operation hereinbefore described are retained. It is also evident that my invention might be employed to separate the component elements of other mixtures than that mentioned and that it might be employed to separate solids existing in the forms of particles of different sizes. For instance, a fine sand might be separated from broken stone by giving the screen-like partitions 9 a mesh which would allow the sand to pass through, but would not permit the particles of broken stone to pass through.

Having, therefore, described my invention, what I claim as new, and desire to protect by Letters Patent, is"

1. An elevating and separating wheel hav ing two series of pockets adapted to discharge at different elevations and formed by partitions, the partitions forming one series of pockets being penetrable to one constituent of a given mixture, while the partitions forming the other series of pockets are impenetrable to both constituents of said mixture, combined with separate discharge-receptacles arranged at different elevations to receive the materials dropped from the respective series of pockets.

2. An elevating and separating wheel have ing two series of pockets formed in its interior by partitions arranged at different angles to the radii passing through them, combined with separate discharge-receptacles arranged at proper points to receive the materials dropped from the respective series of pockets.

3. An elevating and separating Wheel having two series of pockets formed adjacent to its circumference by partitions, the partitions forming one series of pockets being penetrable to one constituent of a given mixture, while the partitions forming the other series of pockets are impenetrable to both constituents of said mixture, the partitions forming one series of pockets having a different angle of inclination to the Wheel radii which pass through them from that which the partitions forming the other series of pockets have, combined with separate discharge-receptacles arranged at different elevations to receive the materials dropped from the respective series of pockets.

4. An elevating and separating wheel having two series of pockets formed within its rim by artitions, the partitions forming one series 0 pockets being imperforate, and those forming the second series being perforate, and placed one in advance of each one of the other series along the line of circumferential travel of the wheel, the partitions forming either one of said series of pockets being considerably inclined to the wheel radii passing through them, and those forming the other of said series of pockets being approximately ICO IIO

parallel to the wheel radii passing through them.

5. An elevating and separating wheel having a series of water-tight pockets formed inside of its rim, and a series of perforate partitions placed in each pocket upon the bottom thereof and inclined toward the interior of said pocket.

6. An elevating and separating wheel having an annular space in its periphery divided into a series of buckets circumferentially disposed by a series of imperforate partitions, and a second series of perforated partitions overlying and separated from the first series of partitions.

7. An elevating and separating wheel having an annular space in its periphery, divided ALFRED MAGUIN.
