To all whom 'it may concern.'

Be it known that I, ELMER A. SPERRY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga ad State of Ohio, have invented new and useful Improvements in Centrifugal Machines, of whlch the following is a specicatlon.

My invention relates to. centrifugal or hydr -extractora and it specially -relates to continuously acting apparatus ofl this -character and consists in means for causing 'a discharge movement of the materials, especially granular and Inobile 1naterials, toward a discharge point and from a point at which the material is delivered Within the centrifugal device, and it consists essentially in apparatus designed to bring about this end, the nature and construction of which is fully described herein, and the essential features o-f novelty po-inted out in the claims hereto annexed and forming a part hereof.

The means employed in the present invention are extremely simple, and may be con structed in various forms, and will readily be understood from the drawings herewith, which show acontinuous centrifugal appa ratus embodying one form of construction which serves to illustrate the action of the device; but the invention should in no wise be limited in its scope to the construction shown in accompanying drawings, in which;

Figure 1 is a vertical section of one form of the apparatus; Fig. 2 is a diagrammatic view of the rot-ating basket showing a plurality of rotating strippers or ejectors and other details. Fig. 3 is an iso-lated View of a pair of ejectcrs o-f different lengths and angles, showing a power connection; Fig. 4 is a form of ejector withla screwlike blade or blades; Fig. 5 is an alternate form 0f ejector disk or blade; Fig. G illustrates a roller bearing for mounting or journaling the rotating ejector, also other details,v.together with a hollow form of ejector disk or blade.

A rotating basket offany' of the usual forms or constructions is illustrated 10, supported by the central shaft 11 through the medium of the base plate 12 Ihaving radial webs 13 radiating from a central hub let and keyed andsecured to the conical part of the shaft 1l. Thisshaft'may protrude from below, or it may depend from the usual bearings and suppo-rt above, which form 1s de signed to bte-illustrated in the drawing. The

basket may be straight sided, or the sides may be o-f any contour. For some purposes, however, it is found preferable to make it of the conical shape illustrated, where it narrowsto the discharge end, which .may or may not be furnished with the ring 15. In the present instance this ring is shown to have an outward and downward inclined projection or lip. The basket 10 is furnished with the usual perfor-ations, not be reinforced by other rings 16 as occasion demands. Surrounding the basket is the usual stationary casing 17 supported upon' standards or One or more of these risers are furnished with means such, for instance, as the rod or rods 20, the nature and use of.which will be described below. The casing 17 terminates below in a channel 21, which for` of which is considerably inclined, as shown by thedott-edY lines, and at its lower point communicates with the discharge pipe 25 .leadingin any direction therefrom, preferably downwardly as illust-rated. The inner and lower cavity terminates near the top of the basket, but preferably by an int-urning projection just under the overhanging ring 15. To afford easy access, covers may be used upon these cavities which may inclose the entire'apparatus or its outejgjy portion only, which latter arrangement illustrated in the drawing by the section`lcovers 26 which may be furnished with N handle 27 and derive their support in any suitable means,v as, for instance, the hoolls 30 engaging the L-shaped ring o r projection 31, or they may be still more securely locked in position by any form of jointor tongue and may or may risers 18 of any suitable and groove, one form of the latter being shown. The apparatus lbeing designed'for continuous operation, it is providedfwith both the induction and eduction apparatus which is adapted to this end.` Any form of induction apparatus instance; the feed tube 33 having a receiving bell4 and a discharging rbell .or ori-tice 35, and maysurrcund in part the cent-ral shaft l1 and be provided with. the sleeve 36 whichldoesnot necessarily engagethe shaft.

The bracket 44 may be supported inany Amanner so as to be adjustable in any of thevarious manners above described.

For certain purposes it becomes necessary to wash, steam, cook, agitate or otherwise treat the contents of the basket, preferably during the process of spinning or treatment under the centrifugal action. To facilitate this-process and to cause it to be very much more effective, it is thought wise to apply the special treatment mentioned through the rotating disksior blades, but in this instance they are made hollow and suitably apertured for this purpose, inasmuch as these disks' continually enter into and are constantly deeply cutting the mass of the substance under treatment, 'andinasmuchas this requires only slight alteration in the structure of therotating element. Details have been illustrated in Fig.' 6 of one form of the device lwhich may fulfil the double purpose ofacting as an ejecting means and at the same time perform the functions of steaming, heating, washing, or the'like. Fig.,6 also serves to illust-rate not only resilient support, piped connection, but also one form of ball or roller bearing. Upon the exterior of the sleeve 41 'are slipped thimbles 70, which may have apertures 71 communicating with the interior of the sleeve 41, vwhich is in turn communicated with the hollow stem 43 by lateral vents 72. .Between tlie'lower tliimbles and the part 73 is iinpinged the lower half of the in'closed disk 42 -42. rlhese disks are preferably given an inverted spherical dish 7 bringing the peripheral edges together at point 74, which edges may be notched as shown at 7 5 or ncaa` the edges a pertures may be provided as shown at 76. This de eiiptioii covers each member of the series of pairs of disks 42-'42,.the interiors of which will be seen to communicate with the pipe 19. Thus it will be seen that a pressure, either negative or positive, of a liquid or `gas communicatedto pipe 19.v

It will vent communication with the exterior *ta-ins the packing 78 impinged by "follower 79, the lower' edge of the body serving to impinge the edges of all of the disks 4 2 and tliimbles 70. The ball bearing at the base of the rotating part is inclosed in the cap 46,

the rollers ,being impinged between the lower race 45 and' the upper race 80, the former `being supported upon the pin depending from the lower end of the stein 43, and the latter finding its support in the spindle 41 below. the projection 73.

Having now described my invention. and one method of carrying its essential details into effect, its use and operation will be apparent. It will be assumed that the basket 10 is rotating'at a constant speed suited to the special material to be treated or dried. This Amaterial in its wet sta-te flows into the tube 33, being urged downwardly by projections 37 of essary, arriving vupon the bottom plate of It quickly-takes centrifugal force carries it outwardly and upwardly on the surface l2 until the peripheral upward bend directs` it on to the perforated port-ion `1O of the basket proper. rThis basketmay receive the usual coverings, differing with different materials, upon which the substance accumulates as the liquids are forcibly ejected, this going on clear around on the interior surface in the As the vm'aterialJvit-hin the basket is spun at one -or more points in its revolution, it encounters the blade or blades or the series of disks 40 upon the ste-m 41 which is power driven through lthe roller bearings, such as have been illustrated' at 45. The periphery of the blade or disks cut. into t-he substance to a greater 'or less depth and the blades or disks are caused to rotate through the impingement thus secured. This rotation` is found to take place with more `virfor than would be expected, owing to the fact that the crystals or substance through the intense centrifugal action becomes exceedingly dense and` forms a compact mass against the inner. wall of the basket, that is, the blade or disk takes, on a motion that is in the same direction and a peripheral s peed that approximates that .of the material within and on the inner wa/ll of the basket; this is especially true with the spiral form. The speed ofthe blade or blades 40 will at once be seento be adifferential speed, and for 'some purposes .is obviously more suited to ,the performance of its functionsrby being thus differential, either if driven through be obfreedom of rotation served that the simple cutting of the rotation of the blade or blades or disks into the moist mass as it sweeps past'. the region of the rotatable member would accomplish nothing in point of movement or transport of the masses from one point to another. lt, however, avails as a means of treatment of the substance constituting the mass, as has been exj'ilained in connection with the form of apjpiaratus deseribet'l in Fig. (l, but as this is a secondary object, the primal objecta'namely, that of mnving and finally ejecting the dry material is not accomplished if the axis of the rotatable men'iber remains vin the plane of the shaft 1l. or the plane of parallel radii of the basket. lf, however, this axis'is tilted out of this plane, even to a 'very slight degree, in such a manner that its lower end trails with the. motion of 'the basket, so that the portion of the blade or disk' which comes next to or is tangential to the inner will of the revolving basket, or that part of such blade as impinges the material upon the inner wall of the basket, is out of the transverse plane of basket the desired result brought about.

lllhen the-blades are disk-like, as in Fig. 1, it is not necessary to the function that the speed be ditl'erential, though usually this is the case, through the imperfect driving scoured by in'ipingelnent as stated. 1When the relation of angle and speed are as stated, a marked change comes over the drying masses within the basket, and they are found to gradually more upi'ardly, being dried more and more as they are spread, mobilized and agitated through lthe action of the. series of rotating disks. This gradual yet continuous upward movement of the mass persists until the .top of the basket is reached, when it is found to be forced outwardly over the edge and in this manner ejected and rcv moved rlear of the basket, being suitably caught as by [lying into the outer circular cavity 2.2i, and finally passing out through the tube or tubes 2T vprovided for this purpose. lhe reason for the upward movement of the masses will be apparent from Fig. 1. The tilting of the blades or their angle in theregion of inipingemeat is such that they enter the masses al a lower point than that at which they leave the masses, this causing a slight lifting or upward movement equal in extent to this elevation of one end of the chord over the other, this chord representing the in'nnersion depth of each sweep of the blade. or each disk into the masses. For some conditions or characters of materialit may be found preferable to 'use a plurality of blades or groups of disks rotating upon their axes as illustrated in Fig. 2. When so used, they are adjusted to height in a certain relation to each other, which, for the best effect, should be a half or a third of the pitch distance between adjacent blac es,

lawrence as the case may be, dependent upon a num.- ber of groups present. The action of such a plurality of groups consists of a slight elevation of the material by each group, such that the blade ordisk 40 of the next group will catch and continue the upward move-v ment. The greater the angle of the blade at the point of impingement the more rapidly is the material removed, and the less the angle the longer the material is retainedhence, slower its ejection and the drierA the.

material. The incidental function of this device as an agitator to the mass, thereby greatly facilitates the drying or other treatment, is a very lvaluable one as it is found to still further facilitate and hasten the action. The action of the hydro-extractor, provided with this device, becomes a continuous one, and the basket requires no stop ping or even change in speed while treating a large quantity, even many tons of material. It has been estimated that the increase of capacity of a. given centrifugal with granular material is many times the amount of work performed by the old method.

Where the masses tend to become hard as they are compacted by the centrifugal action, the notched blade or disk shown in Fig. 3 may be employed. there itis desirable that the material be thinned downat any point in the basket, as, for instance, in the center of the height of the basket to save undue strains in this portion or at the top of the basket to facilitate the removal of the material at a given point, the arrangement shown in Fig. 3 may'be employed, where the material is elevated to a point by the slowerl processand then removed more rapidly by the rotar y ejector which is placed at a greater angle as shown. The liquids are drained in the usual manner by gutter 21, discharge pipe or its equivalent 22. The roup of disks may be supported and adjusted by any well known means, one foi-1n of which is shown in Figs. 1, 2 and 3, withl an alternate form in Fig. (i. The remow; of the rotating member as a whole is facile tated by wheel 50 driving a pinion which eooperates with rack 4S upon the stem 20. 'libe tilting action is secured between the stem ll2 and the lsocket 17 as is also the depthito which the disks are forced into the masses of substances contained in the basket, this latter by adjusting the stem 52 inwardly and outwardly from the socket. The screws 51 and 53 serve to clamp the parts into position after adjustment. The angle of the blades isillustrated in Figj and Fig. 4,.

and also in Fig. 1, the arrow about the shaft 11 indicating its direction of movement. When it is desired to simultaneously treat the substance as Well as eject, the device takes the form illustrated in Fig. 6, where the heating, moistening, or other treatment is in part delivered into the interior masses of the material through the disks themselves as they enter the substance. It is designed to use the parts substantially 'as and in the relation shown. It is apparent, however, that some may be omitted and others may or may not be substituted, and the invention extends to such use. y
