I Toall whom it may concern.-

Be it known that I, WILLIAMALEXANDER WOD,a citizen of the United States, reside ing at Ansonia, inthe Stateof Connecticut, have invented a Continuous Centrifugal Ma chine, of wh ich the followingis a specification. My continuous centrifugal machine .con-. sists, essentially, of aninclosing casing, a revolving; basket having dischargeaopeni ngs, a IO series of revolving wingswithin the basket, and mechanism by reason ofwhich the speed of .the basket relatively to that of y the. wings may beadjusted, whereby the solid material in the basket will'atintervals bebroughtinto' positions tobe discharged through the lateral openings in thesides of the basket. I-will describe my improved machine in connection with the accompanying drawings, and then point out in the claims whatjI consider to be my invention.

Figure 1 is a front elevation; Fig.2 is. a 7 vertical section. Fig. 3 is a plan view showing a portion of the cover'broken away and a portion of the feed-ch ute in a horizontal section,-the view beingl taken on the line W W of Fig. 2. Fig. 4 is a" horizontal section on i the lineX X of Fig. 2. Fig. 5 is a horizontalsection on the line Y Y of Fig. 2. Fig. 6 is a horizontal section on the line V V of Fig. 30. 2. Fig. 7 is a vertical elevation showinga modification of the mechanism for regulating the speed of rotation of the basket. Fig. 8 is a detached-view from the large view of the I arm which carries the spring-pressed pawl under the revolving basket. Fig. 9 is a face view of one of the lateral openings of the revolving basket. t I v V In the drawings, 10 is a vertical spindle mounted in the bearings 11 12. The bearing 12 is' made adjust ble by means of thescrew .13. 14 is a pulley keyedto the spindle 10 and adapted to transmit rotary motion to the spindle. Instead of using a long spindle with a pulley mounted on the upper part, as shown A in the drawings, I may, as is common in centrifugal machines, use a short spindle and mount the pulley below. the basket.

The inclosing casing 15 iscomposed of the rim 15, base 15",,and body 15. The casing 15' as a whole is carried by means of the rods 16, which depend from the casting 17,carried bythe u niversaljoint18, which latter? ispsuitably secured to any horizontal support. (Not shown.) The base 15 of the easing 15 has formed in ittwo channels 15*15. The channel15 is open at'the bottom, so that any solid naterial for instance, sugar after spinning, which is dischargedinto the chanuel-may pass freely out of the machine. The channel 15 has a closed bottom and is separated from the channel 15 by the wall or flange 15". The channel l 5 hasits bottom inclined downward towardlthe discharge-spoutlc'fl,so that any liquid discharged into the channel-as, for instance, the liquor extracted from sugar' in spinning-will flow freely. from the machine through the-spout 15 Depending from the base 15? re the rods 19, whichsupport the lower b aring-12, the spindle l0, and parts carried by the spindle. t f

Located within the casing is the rotatable basket 20. The basket is. composed of the cover 20,.-b0ttom portion 20", exterior body 20, and interior perforated body 20, Formed in the cover 20 is the central hopper 21, p which extends downward into the basket and h is provided with the delivery-chutes 22. The body of the hopper is so formed as to have situated at its center the central hub 23,which is bored to receive the spindle 10, but which is not attached to the spindle. The interior diameter of the hub 23 is such that it may rotate freely around the spindle. The bottom portion 20 consistsof the disk 24, having the central hub 25 bored to receive the spindle 10.

The hub is not connected to the spindle and is sufliciently large on its interior diameter to move freely around the spindle.

Depending from the outer periphery of the disk 24 and adapted'to more over the wall 15* is a flange 26. Immediately within this flange is a second flange 27, which projects downward and is adapted to niove within the chan nel 15 Projecting upward from the disk 24 is another flange 28, and between the flange 5 27 and the flange 28 are arranged openings 29. These openings, itwill beobserved, are

situated over the channel 15 A second hub 25 projects downward from the disk 24 and is somewhat larger in diameter than the hub25. too

The cover 20 and the bottom portion 20 are connected through the outer bodyportion.

. The trunnions 41 have their bearings in the and the perforated inner body portion 20.

Q The outer body portion 20- is made of sheet metal and is connected at the top to the outer periphery of the cover 20 and at the bottom to the outer periphery'of the disk 24 and between the flanges 26 and 27. The inner body portion 20 is made of perforated sheet metal or wire-gauze and is connected at the'top to the cover 20 and at the bottom to the inner side of the upwardly-projecting flange 28. Surrounding the perforated inner body portion 2O are parallel strengthening-rings 30.

Mounted on the collar 10" and keyed fast to the spindle 10 is a worm-gear 31. (Best shown in Fig. 5.) Carried in bearings 32, which depend from the disk 24 of the bottom portion of the basket, are the worm-shafts 33,

(two are shown, but only one may be employed,) in gear with the worm-gear 31. On the opposite endsof the worm-shafts are the ratchets 34. Depending from the worm-shafts 31 are the arms 35. These arms are not keyed upon the shafts 33, but are merely supported thereby.

Mounted on the outer side of the depending portions of the arms 35 are the spring-pressed pawls 36, which engage with the ratchetwheels 34. The arms 35 are connected through the1inks'37 with the vertically-movable block .38. The block 38 is bored to receive the spindle is fastened a collar 38*, having pivotal bearings for the links 37. 'lhehub 38 is also provided with a horizontal flange 38 and a removable ring 38 Surrounding the hub 38 and between the flange 38 and ring 38 is an independent ring 39. Between this ring 39 and the flange 38 and the ring 38 are interposed balls 40, which form antifrict-ion-bearings. The independent ring 39 is provided with the lateral trunnions 41.

42 is a bifurcated lever pivoted in the bear; ing 43, which is secured to one of the rods 19.

' sides of the bifurcated lever 42.

It will be understoodthat the independent ring 39, while vertically movable, does not rotate with thespindle 10 and the block 38, but

.is stationary, so far as rotation is concerned,

' located a bolt 46, by means of which a connecting member 47 is adjusted in the slot.

In the construction shown in Fig. 7 the end 44 is provided with a slot along its surface and a screw-threadat each nd. The conends of the slot.

necting member 47 has its base-located in the slot, and this base is threaded. An adjusting-screw 48 engages the threaded portion of the connecting member 47 and the threaded Adjustment is effected by means of a hand-wheel 49.

50 represents a rod connected at one end to an eccentric 5l'on the shaft 52 and at the other end adjustably connected to the connecting member 47 by means of the nuts 53.

It will be understood that \vhenthe shaft 52 is rotated, which rotation may be derived shafts 33 with the result. of imparting a motion to the basket in a direction opposite to that'impa rted by the rotation of the spindle 10. In other words, assuming therotation of the basket imparted by the spindle to be from left to right, as indicated by the arrow in Figs, 3 and 4, the rotation imparted by the worm-shafts will be from right to left, as indicated by the arrow in Fig. 5. The result of these two rotations, therefore, will be a speed of rotation of the basket less than that of the spindle. By adjusting the connecting member 47 relative to the lever-arm 44 the degree of vertical motion imparted to the block 38 can be altered, and consequently the speed of rotation of the basket relative to that of-the spindle likewise changed.

The object of the arrangement above described for regulating the speed of the basket will hereinafter be explained and described in the operation of the device.

Located within the basket 20 and keyed to the spindle 10 is a spider 54, (best shown in Fig. 4,) provided with radial wings 55, twelve being shown. The wings are bifurcated at their outer ends to carrytthe vertically-arranged scrapers 56. Located behind the scrapers andin the bifurcations of the wings are the springs 57, which form a resilient base fast to the spindle 10, and therefore has the.

same speed of rotation as the spindle. Consequently if the speed of rotation of the hasket' by reason of reciprocation of the block 38 be made less than that of the spindle then the scrapers 56 will scrape over the inner surface of the perforated body 2O and gradually move any-material located between any pair of wings toward lateral openingsfiO, arranged through opposite sides of the basket 20. In Fig. 9 I have shown a vertical elevation of the framework of one of these openings. In practice the vertical diameter of the framework is less than that of the scrapers, so that the scrapers will not lie-thrown out ofthe open-' material acted on in the machine. It-will also be observed that the position of the feed. chutes 22 is such that they do not register with the openings 60, but feed into the second spaces between the wings from the openings in the directionof rotation of. the arms.

- I do not wish to limit myself in any wise to.

the position shown for the feed-chutes, as

they may be moved nearer to or farther away from the openings. The position shown in the drawings, however, isthe one which I consider best.

i The operationof myimproved device is as follows: Theimaterial to be acted on, which is in a wet state, is fed continuously in any suitable mannerinto the revolving hopper 21 of the basket 20and is delivered through the chutes 22 into the spaces between the wings 55. The material is thrown out by centrifugal action againstthe perforated body 20 and at the same time is advanced in its position in the rotating basket toward one of the dis. charge-openings. The rapidity of the ad- Vance will depend, as described, by the difference in speed between that of the rotating Wings and that of the basket. The degree of the advance in the basket maybe determined in advance, thus: Given a material to be acted upon containing a definite amount of moisture, the degree of advance of the material in the basket may be made such that the material will reach the discharge-opening when I the requisite spinning has been reached-i. e.,

the degree of moisture has been extracted.

In the operation of the machine the liquids, &c., are discharged through the perforations in the body20 and gathered in the channel 15 and conveyed therefrom through the spout 15 whereas the dried material will be discharged through the openings 60 into the channel 15 and thence into suitable receptacles. It will be furtherobserved that the construction of this machine is such that there will be no mingling or possibility of mingling of the extracted liquids and solids. I have shown no means in the drawings forv operating the shaft- 52. Manifestly it may be driven in any suitable manner to produce the required reciprocating motion of the block 38;

I wish it understood that I do not limit myself to the specific construction described and shown in the accompanying specification and drawings, as I believe I am the first to describe a continuously-acting centrifugal machine which involves the principle of a difierence in speed between a horizontally-rotating basket having'suitable vertical dischargeopenings for the solid materials and a series of independent vertical wings located and rotated within the basket.
